Treatment of a leaking ACE conduit with Deflux injections.

Faecal leakage from the catheter conduit can be troublesome and reduces the convenience of use of antegrade continence enema (ACE). We report the results of Deflux injection treatment for leaking ACE conduits in nine patients. From 1994 to the end of 2005, 81 patients underwent a procedure for ACE [appendicostomy with wrap (AW) n = 29, appendicostomy straight (AS) n = 44, Monti-Yang ileal tube (MY) n = 5, lateral caecal flap (LCF) n = 1, caecal tube (CT) n = 1, sigmoid tube (ST) n = 1]. Nine (11%) patients (AW n = 3, AS n = 1, MY n = 3, LCF n = 1, ST n = 1) had persistent stomal leak and underwent Deflux injections of the ACE conduit. With the patients in general anaesthesia, the conduit was visualised with CH10.5 cystoscope. At the junction of the conduit and colon, 0.5-1.0 ml of Deflux was injected submucosally at three sites to create intermingling mounds in order to narrow the conduit. After the injections, a balloon catheter was left in the conduit for 3-7 days. When necessary, the injections were repeated. The result was graded as no improvement, moderate improvement, significant improvement. Nine patients underwent a median of 2 (range 1-4) injections. No major complications occurred. The results after a median follow-up of 22 (range 3-53) months from the first injection were as follows: no improvement (n = 1), moderate improvement (n = 5), significant improvement (n = 3). Repeated injection of the ACE conduit with Deflux is a low invasive method and provides moderate to good results in the majority of the patients who suffer from faecal leakage from conduit.

Revision of prolapsed feeding gastrostomy with a modified Janeway 'gastric tube'.

After creation of open or percutaneous endoscopic gastrostomy, gastric prolapse and leak of gastric contents may cause serious skin rash and infection which are often difficult to treat. We present four patients in whom these problems were solved with gastrostomy revision by a modified Janeway 'gastric tube' technique. The patients were aged 7 months and 7, 10 and 16 years at the time of the revision. The underlying conditions were hypoxic encephalopathy with epilepsy, infantile spasm and epilepsy with arthrogryposis, dystonic tetraplegy, and total colon aganglionosis. All patients had gastrostomy prolapse with peristomal skin rash and cellulitis. Prior to modified Janeway revision, the four patients had undergone a total of 16 failed attempts to cure the prolapse. At the operation, the previous gastrostomy was detached and closed. A longitudinal gastric tube of 6 cm was created along the greater curvature with a GIA stapler and brought through the abdominal wall leaving 3-5 cm of free intra-abdominal gastric tube. A balloon catheter was left for 6 weeks, and replaced with a long Mickey tube according to patient's or caretaker's preference. There were no surgical complications. Hospitalisation after revision was median 6 (range 4-11) days. Six weeks after the revision, prolapse, leak and peristomal infections were cured in all patients, and feeding through the gastrostomy presented no problems. One patient underwent minor excision of excess stomal mucosa. Two patients opted for Mickey tube, two for a feeding catheter. A median of 9 (6-16) months after the revision, all patients have a functioning gastrostomy without prolapse or leak. Modified Janeway 'gastric tube' revision is feasible and, within short to medium term follow-up, controls efficiently gastrostomy prolapse and leak.

Long-term outcome after internal sphincter myectomy for internal sphincter achalasia.

Anal internal sphincter achalasia is a rare cause of refractory constipation. It is usually treated by internal sphincter myectomy (ISM). The aim of this study was to evaluate the long-term outcome of patients who had undergone ISM for internal sphincter achalasia. Bowel habits, fecal continence, and quality of life were evaluated using a questionnaire. Fecal continence was quantitatively assessed by a score described by Holschneider. A questionnaire was sent to 13 patients (11 male, two female) operated on by ISM for intractable constipation caused by internal sphincter achalasia between 1983 and 1993. Ten patients responded and were included in the study. At the time of the study, three of the 10 patients required oral medication for constipation and had one to three bowel movements per week. One of the 10 patients had three to five bowel movements per day, and the others had one to two bowel movements per day. Four patients had normal and six patients had good continence scores. Four of the patients reported mild social problems, and one had problems associated with sports. Refractory constipation in the majority of patients with internal sphincter achalasia can be treated by ISM. However, in the long term, a significant number of patients suffer from soiling-related social problems.

Does postoperative pH monitoring predict complicated gastroesophageal reflux in patients with esophageal atresia?

Gastroesophageal reflux (GER) is common after repair of esophageal atresia with a distal tracheoesophageal fistula (EATOF). In a retrospective study we assessed whether early 18-h pH monitoring can predict the development of EATOF-associated gastroesophageal reflux. During 1980-1997, 90 consecutive patients had primary repair for EATOF. Development of GER was classified as favorable if the patient developed no esophagitis or mild esophagitis and needed no antireflux medication, and as unfavorable if the patient developed moderate or secondary esophagitis or required an antireflux procedure. Patients who developed unfavorable GER outcome before pH monitoring or needed secondary reconstruction or those whose endoscopic follow-up data were insufficient were excluded. Eighteen-hour pH monitoring was considered pathologic if esophageal pH was <4 more than 10% of the recorded time or 5% of the recorded time minus 2 h after each meal, or if there were more than three preprandial reflux periods lasting longer than 5 min. A total of fifty patients were included into the study. pH monitoring was performed at the median age of 9.2 (range 2.5-95.0) months and classified as pathologic in 10 and normal in 40 patients. After a median follow-up of 59 (0.3-217.6) months, nine of 10 (90%) patients with pathologic pH monitoring and five of 40 (12.5%) patients with normal pH monitoring developed unfavorable outcomes ( p<.05). We conclude that early pH monitoring predicts the development of significant GER, but because 12.5% of patients with normal early pH monitoring also developed significant GER, early pH monitoring alone does not rule out the development of significant GER.

Comparison of functional outcomes of Duhamel and transanal endorectal coloanal anastomosis for Hirschsprung's disease.

PURPOSE: The aim of this study was to determine the morbidity and medium-term functional outcome of the Duhamel operation and laparotomy and transanal endorectal coloanal anastomosis (TECA) for Hirschsprung's disease (HSCR). METHODS: The study populations were 34 consecutive children who underwent the Duhamel operation (or Lester Martin modification) and 37 who had the TECA. Demographic details were obtained by case note review, and functional outcome was determined by a combination of outpatient interview, questionnaire, and telephone enquiry. RESULTS: There was no difference between the groups with respect to age, gender, and length of aganglionic segment. Seventy percent presented as neonates (Duhamel, 24 of 34; TECA, 26 of 37). A single-stage primary pull-through was performed in 17 of 37 children in the TECA group, and in 1 of 34 from the Duhamel group. There was a single perioperative death in the Duhamel group and an unrelated, late death in the TECA group. Postoperative enterocolitis was seen in 13 of 37 TECA children and in a single child from the Duhamel group. A stricture of the pull-through segment was seen in 7 of 37 children after TECA and required temporary diversion in 2 of 9. Late division of a rectal spur was required in 6 of 33 Duhamel children. Requirement for late myectomy was the same in both groups (Duhamel 3 of 33, TECA 4 of 37). Complications requiring stoma formation occurred in 5 of 37 after TECA and 2 of 33 after the Duhamel operation. Two children from the TECA group and 1 from the Duhamel group remain diverted. One child from each group required a re-pull-through procedure. Two patients were lost to follow-up in the TECA group, leaving 34 children in this group and 33 in the Duhamel group in whom functional outcome could be assessed. Functional outcome was similar in the 2 groups. CONCLUSIONS: TECA and Duhamel procedures have similar medium-term functional outcomes. TECA has a high incidence of postoperative enterocolitis and transient stricture formation but is suitable for single-stage neonatal treatment of HSCR.

Early outcome of transanal endorectal pull-through with a short muscle cuff during the neonatal period.

BACKGROUND/PURPOSE: Transanal pull-through has been advocated recently for classic Hirschsprung's disease. The procedure leaves no scars, is associated with less postoperative pain and discomfort, and shortens hospital stay. Long-term functional outcome of patients having transanal pull-through is unclear, but short-term function is reported to be very similar to that after open or laparoscopic procedures. One-stage neonatal repair of Hirschsprung's disease has been suggested to be associated with less cost and demand of resources without jeopardizing functional outcome. The aim of this study was to ascertain the feasibility and safety of transanal pull-through in the neonatal period. METHODS: Case notes of 40 consecutive patients who had undergone transanal endorectal pull-through for Hirschsprung's disease between January 2000 and February 2003 were reviewed. The patients were divided in to 3 groups: patients with neonatal primary pull-through (group I, 15 patients), patients operated on beyond the neonatal period (group II, 11 patients), and patients with a previous colostomy (group III, 14 patients). All colostomies except one were taken down and pulled through concomitantly with the transanal procedure. The case notes were evaluated for hospital stay, time to full oral feedings, operative and postoperative complications, need for postoperative dilatations, and occurrence of postoperative enterocolitis. RESULTS: There was no difference in median hospital stay (group I, 5 days; group II, 4; group III, 5) and median time to full oral feedings (group I, 4 days; group II, 2; group III, 3) between groups. Two patients (group III) had immediate postoperative prolapse of the pulled-through colon that was reduced without further sequels; 1 (group III) had infection of the stoma closure wound. Perianal skin rash that usually resolved within 6 weeks occurred more often in neonatal patients (group I, 10 of 15; group II: 4 of 11; group III: 8 of 14). Anastomotic dilatation regimen was required more often in neonatal cases (group I, 6 of 15; group II, 1 of 11; group III, 2 of 14). Enterocolitis requiring hospital care occurred in 2 patients (group I), 5 further patients (group II, 1; group III, 4) were treated as outpatients for symptoms suggesting mild enterocolitis or bacterial overgrowth. The median follow-up was 6 months. CONCLUSIONS: Transanal endorectal pull-through in neonatal patients is as feasible and safe as in older children or in those with a levelling colostomy. However, temporary postoperative skin rash occurs more frequently in neonatal patients, and postoperative dilatations are required more often than in older children.

Is routine dilatation after repair of esophageal atresia with distal fistula better than dilatation when symptoms arise? Comparison of results of two European pediatric surgical centers.

BACKGROUND/PURPOSE: The aim of this study was to determine whether routine dilatation of the anastomosis after repair of an esophageal atresia with distal fistula (EADF) is superior to a wait-and-see policy with dilatation only when symptoms arise. METHODS: The records of 100 consecutive patients operated on for EADF in 2 European pediatric surgical centers (A [n = 63], B [n = 37]) were reviewed. In center A, dilatation of the anastomosis was carried out in symptomatic cases only, whereas in center B dilatation was begun 3 weeks postoperatively and repeated every 1-3 weeks until a stable diameter of 10 mm was reached. Particular attention was paid to the number of dilatations per patient, dilatation-related complications, and differences in results after 2 years. RESULTS: The patient materials of both centers did not differ with respect to the incidence of prematurity, tracheomalacia, gastroesophageal reflux (GER), and major postoperative complications. The incidence of associated anomalies was higher in center B (P < .05). In center A, 26 of 63 patients underwent dilatation; in center B, all 37 patients were dilated (P < .05). Median number of dilatations per patient was 4 in center A and 7 in center B (P < .05). In center A, 23 of 26 and in center B, 20 of 37 of the patients received medical treatment for GER at the time of the dilatations. Dilatation-related complications developed in 7 of 26 patients of center A and in 3 of 37 patients in the center B (P value, not significant). The median primary hospital stay was 24 days in center A and 33 days in center B (P < .05), median secondary hospital stay for dilatation was 6 days in center A and 13 days in center B (P < .05). After 2 years of follow-up, the incidence of dysphagia, respiratory problems, or bolus obstruction did not differ significantly between the 2 centers. CONCLUSIONS: A wait-and-see policy and dilatations based on clinical indications for patients with repaired EADF is superior to routine dilatations. It appears that more than half of the patients do not require dilatations at all.

Transanal coloanal pull-through with a short muscular cuff for classic Hirschsprung's disease.

INTRODUCTION: A totally transanal operation for classic Hirschsprung's disease has become increasingly popular during the last few years. The procedure leaves no scars, is associated with less postoperative pain and discomfort and shortens hospital stay. The most commonly used technique for transanal pull-through is long endorectal dissection leaving a long muscular cuff, which is usually split posteriorly. We present our preliminary results following transanal endorectal operations with a short unsplit muscular cuff. MATERIALS AND METHODS: Twenty-six patients underwent short-cuff transanal endorectal operation for Hirschsprung's disease between years 2000 and 2002. Patients' hospital records were analysed retrospectively. The collected data included age at operation, associated conditions, hospital stay and time to full enteral feeding, occurrence of pre- and postoperative enterocolitis and preoperative stoma, operative complications, need for postoperative anal dilatations, postoperative perianal skin problems and preliminary data on bowel function. RESULTS: The median age at operation was 1 month (range 0 - 60 months), 13 patients were operated on in the neonatal period. Four patients had Down's syndrome, 1 had cartilage-hair hypoplasia and one Ondine's syndrome. Five patients had preoperative enterocolitis. Four patients had undergone levelling stoma formation for unremitting constipation or enterocolitis. The proximal ganglionic stoma was concomitantly pulled-through and anastomosed to the anus in all 4 patients with a stoma. One patient with aganglionosis extending to the proximal sigmoid required additional laparoscopic colonic mobilisation. Complications related to surgery did not occur in the present series. Median postoperative hospital stay was 3 days (range 2 - 21 days) and median time to full enteral feeding was 3 days (range 1 - 14). Six patients required anal dilatations, two of those for a period of 3 weeks. The median follow-up time was 6 months (range 1 - 22 months). Fourteen patients had perianal skin rash, which usually resolved within 6 weeks. Postoperative enterocolitis requiring hospitalisation occurred in 1 patient, another patient had mild symptoms suggesting enterocolitis; these responded to oral antibiotic treatment. Early postoperative bowel function was characterised by frequent bowel movements in most patients. This usually resolved within a few months; of the 15 patients with a follow-up of longer than 6 months only 2 have more than 3 bowel movements per day. At the last follow-up frank soiling occurred in 1 patient with Down's syndrome, one patient requires oral laxatives for constipation. CONCLUSIONS: Transanal endorectal pull-through with a short cuff is a safe operation with a low incidence of operative and postoperative complications. Hospital stay and time to full enteral feeds is significantly shorter than after conventional procedures; this is associated with lower hospital costs. Long-term functional outcome is unclear but short-term function is very similar to that after procedures where transanal mucosectomy is combined with open rectosigmoid dissection.

[Transanal endorectal pull-through with short muscular cuff in the treatment of Hirschsprung disease. Preliminary study with 37 patients].

INTRODUCTION: Totally transanal operation for classic Hirschsprung's disease has gained increasing popularity during the last few years. The procedure leaves no scars, is associated with less postoperative pain and discomfort and shortens hospital stay. The most commonly used technique for transanal pull-through is long endorectal dissection leaving a long muscular cuff, which is usually split posteriorly. We present our preliminary results following transanal endorectal operation with a short unsplit muscular cuff. MATERIALS AND METHODS: Thirty-seven patients underwent short-cuff transanal endorectal operation for Hirchsprung's disease between years 2000 and 2002. Patients' hospital records were analysed retrospectively. The collected data included age at the operation, associated conditions, hospital stay and time to full enteral feeds, occurrence of pre- and postoperative enterocolitis and preoperative stoma, operative complications, need for postoperative anal dilatations, postoperative perianal skin problems and preliminary data on bowel function. RESULTS: The median age at operation was 5 months (range 0-60 months), 13 patients were operated in the neonatal period. Six patients had Down's syndrome, 1 had cartilage-hair hypoplasia and one Ondine's syndrome. Six patients had preoperative enterocolitis. Thirteen patients had undergone levelling stoma formation for unremitting obstruction or enterocolitis, two of these had a long segment aganglionosis. The proximal ganglionic stoma was concomitantly pulled-through and anastomosed to the anus in all 13 patients with a stoma. Complications related to surgery occurred in 3 patients, 2 had prolapse of the pulled-through bowel (reduced immediately without later sequels) and 1 infection in the stoma closure wound. Median postoperative hospital stay was 4 days (range 2-21 days) and median time to full enteral feeds 3 (range 1-14) days. The median follow-up time was 6 months (range 1-22 months). Postoperative enterocolitis occurred in 1 patient, further 3 patients had symptoms suggesting mild enterocolitis. Nine patients required anal dilatations, two of those for a period of 3 weeks. Twenty-two patients had perianal skin rash, which resolved usually within 6 weeks. Early postoperative bowel function was characterised by frequent bowel movements in most patients. These usually resolved within few months; of the 17 patients with a follow-up for longer than 6 months only 2 have more than 3 bowel movements per day. At last follow-up frank soiling occurred in 2 patients, one patient needs oral laxatives for constipation. CONCLUSIONS: Transanal endorectal pull-through with a short cuff is a safe operation with low incidence of operative and postoperative complications. Hospital stay and time to full enteral feeds is significantly shorter than following conventional procedures; this associates with lower hospital costs. Long-term functional outcome of patients having totally transanal pull-through is unclear but short tern function is very similar than after procedures where transanal mucosectomy is combined with rectosigmoid dissection through laparotomy.

Proctocolectomy and J-pouch ileo-anal anastomosis in children.

BACKGROUND/PURPOSE: The choice of ileo-anal reconstruction method in children undergoing proctocolectomy remains controversial. Although in adults ileo-anal pouch reconstruction has gained overall acceptance, many paediatric surgeons still advocate straight ileo-anal pull-through. The aim of this study was to assess the outcome and long-term functional results in children who have undergone proctocolectomy and ileo-anal anastomosis (IAA) with a J-pouch. METHODS: Medical records of 40 consecutive children who had proctocolectomy and J-pouch IAA between 1991 and 1999 were reviewed for early and late complications, fecal frequency, day- and night-time continence, and pouchitis. The indication for surgery was ulcerative colitis (UC) in 29 (median age at operation, 13 years; range, 9 to 16), Hirschsprung's disease (HD) in 10 (median age at operation, 1.5 years; range, 1 month to 5 years), and familial adenomatous polyposis (FAP) in 1 (age at operation, 6 years). Six of the HD patients had primary pull-through for total colonic aganglionosis and 4 a redo operation for failed primary reconstruction of long segment aganglionosis. RESULTS: There were no fatalities. Early complications (wound infection, early bowel obstruction, prolonged fever) occurred in 12 of 29 (41%) and late complications (bowel obstruction 9, pouch fistula 2) in 11 of 29 (38%) of the UC patients. Overall, 16 of 29 (53%) of the UC patients had complications. All patients with early complications were on systemic steroids at the time of the operation. Pouchitis occurred in 30% of the patients. None of the pouches had to be removed. At last follow-up all patients were continent during the day, 2 patients used protective pads during the night because of occasional staining. The median bowel frequency per 24 hours was 4 (range, 2 to 7); only 2 patients (7%) had to empty their bowel during the night. One (10%) of the HD patients had wound infection, and 3 had episodes of postoperative enterocolitis. Pouchitis-type symptoms have not occurred in HD patients. The median bowel frequency for 24 hours was 3 (range, 2 to 5). None of the HD patients needs to evacuate during the night. The 4 HD patients who are older than 3 years of age are continent. CONCLUSIONS: J-pouch IAA is a feasible method of reconstruction in children requiring proctocolectomy. Major complication are common but occur mainly in immunosuppressed patients suffering from UC. Despite high incidence of complications, long-term functional results in terms of continence and bowel frequency are excellent and ensure good quality of life in the great majority of patients.

Morbidity and quality of life in adult patients with a congenital abdominal wall defect: a questionnaire survey.

BACKGROUND: In children with congenital abdominal wall defects (CAWD), surgical treatment of the abdominal defect and the associated anomalies cause considerable morbidity in the first years of life. Afterward, most of the CAWD patients with correctable anomalies develop as other children. The morbidity and quality of life (QoL) of CAWD patients who have reached their adulthood is less well known and the subject of this study. METHODS: A 3-part questionnaire was sent to 75 former patients with CAWD, aged 17 years or more. The first part included questions about health, symptoms, and education; the second part consisted of 3 tests of psychosocial functioning; and the third part was a SF-36 questionnaire measuring the QoL. RESULTS: Of the 75 patients, 57 (76%) answered: (25 males, 32 females); omphalocele (n = 16) gastroschisis (n = 11); median age, 27 (range, 17 to 48) years. With the exception of rheumatoid arthritis (in 7% of patients), the prevalence of acquired diseases in CAWD patients was comparable with that of the general population; 50 of 57 (88%) considered their health good. The most frequent causes of morbidity were disorders in the abdominal scar in 21 (37%) patients, and functional gastrointestinal disorders in 29 (51%) of patients. Low self-esteem was found in 12% of patients, but the QoL and educational level of CAWD patients were not different from that of the general population. CONCLUSIONS: In CAWD patients the morbidity from acquired disorders is similar to morbidity in the general population. Disorders with the abdominal scar and various functional gastrointestinal disorders are common, but they rarely cause serious problems. The majority of CAWD patients have a quality of life not different from the general population.

Fecal incontinence in anorectal malformations, neuropathy, and miscellaneous conditions.

In the majority cases, fecal soiling in children is functional and usually associated with severe constipation. Fortunately, functional soiling is a self-limiting problem and usually disappears at puberty. Organic fecal incontinence is a consequence of congenital malformations affecting the anorectum, anal sphincters, or the spinal cord. Inability to control bowel function may be permanent, as in patients with myelodysplasia; self-limiting, as in patients who have fecal soiling after a pull-through operation for Hirschsprung's disease; or partial, as in many patients who have undergone repair of an anorectal malformation. The purpose of this report is to review the etiology, long-term outcome, and evolution of the management of different types of organic fecal incontinence in children. Knowledge of the pathophysiology of fecal incontinence has accumulated during recent decades, and this provides the basis of modern treatment modalities that have revolutionized treatment so that today most patients can be provided total or at least social continence from early childhood.

Sodium cromoglycate in the management of chronic or recurrent enterocolitis in patients with Hirschsprung's disease.

BACKGROUND/PURPOSE: Chronic or recurring enterocolitis is a rare but perplexing complication of Hirschsprung's disease affecting especially patients with altered immune defense such as those with Down's syndrome. Sodium cromoglycate (SCG) is a nonabsorbable mast cell stabilizing agent that has been documented to be effective in the treatment of inflammatory bowel disease. The authors studied the effect of SCG in Hirschsprung patients with refractory chronic or recurrent enterocolitis. METHODS: Eight patients (4 with Down's syndrome, 2 with other chromosomal aberrations, 2 otherwise healthy; age range from 4 to 22 years) with chronic (5 patients) or recurrent (>6 episodes/year, 3 patients) enterocolitis received 100 to 200 mg of SCG 4 times a day depending on the age of the patient. The chronic diarrhea or recurrent bouts of enterocolitis in the patients were refractory to dietary management and enteral antibiotics. Before the treatment all patients had ileocolonoscopy, the results of which showed macroscopic and histological chronic inflammation in all cases. No neuronal abnormalities were detected in biopsy results. None of the patients had colonic dilatation or increased anorectal resting pressures suggesting outlet obstruction. RESULTS: The follow-up of the patients ranges from 8 months to 26 months. Three of the 5 patients with chronic enterocolitis responded favorably. In these 3 patients the median number of daily bowel movements decreased from 6 to 3, and none experienced bouts of abdominal distension. Diarrhea-related soiling decreased also significantly. Two of the 3 patients with recurrent enterocolitis have remained asymptomatic, and none has required antibiotics after the onset of SCG treatment; one patient had an episode of enterocolitis after 12 months treatment. Two patients with chronic enterocolitis did not respond to SCG. No side effects of SCG were encountered. CONCLUSIONS: This preliminary and nonrandomized study suggests that SCG is an effective treatment modality for chronic or recurrent enterocolitis in patients with Hirschsprung's disease. Because SCG is not absorbed From the intestinal tract there are no systemic side effects.

Fecal continence in patients having undergone posterior sagittal anorectoplasty procedure for a high anorectal malformation improves at adolescence, as constipation disappears.

BACKGROUND/PURPOSE: Constipation is a major complication in patients who have undergone posterior sagittal anorectoplasty (PSARP) operation for a high anorectal malformation. Overflow incontinence is the main cause of fecal soiling in these patients. The aim of this study was to outline the natural history of constipation in patients with high anorectal malformations and relate this to the functional outcome at the end of the patient's growth period. METHODS: The study group consisted of 22 pubertal or postpubertal patients (median age 15; range, 13 to 25) with high or intermediate anorectal malformations repaired by PSARP procedure. The patients have been followed-up since birth. Constipation was defined as a need to use medical treatment or diet to ensure bowel emptying. Continence was classified as follows: grade 1, no soiling in any circumstances; grade 2, staining less than once a week, no fecal accidents; grade 3, staining more than once a week, no fecal accidents; grade 4, daily soiling or accidents, need for regular enemas, or the antegrade colonic enema procedure. All patients underwent anorectal manometry and magnetic resonance imaging of the spine and spinal cord. RESULTS: At the time of the study 2 (9%) of the 22 study group patients had constipation, but 15 (68%) had been constipated before puberty. Eleven patients (50%) were fully continent (grade 1) without constipation. Six of those had a history of constipation associated soiling. Three patients (14%) had occasional staining (grade 2) and no constipation. Two of them had been constipated with significant soiling before the onset of puberty. In the 5 (22%) patients with frequent staining (grade 3) the degree of soiling had decreased after the disappearance of constipation. Two of the 3 patients with poor outcome (grade 4) require regular enemas for recalcitrant constipation. Spinal cord anomalies were detected in 4 and abnormal sacrum in 15 patients. Of the anorectal manometric parameters, only the force of voluntary sphincter squeeze correlated with the functional result. CONCLUSION: In the majority of patients who underwent PSARP procedure for high anorectal malformation, constipation disappears at adolescence, and this is associated with improved fecal continence outcome.

Transanal endorectal coloanal surgery for Hirschsprung's disease: experience in two centers.

BACKGROUND/PURPOSE: Transanal mucosal proctectomy with low coloanal anastomosis has been used widely in the treatment of rectal malignancies, ulcerative colitis, and familial polyposis. The use of this technique for Hirschsprung's disease is a relatively new concept. The aim of this study was to evaluate and compare the results of transanal endorectal coloanal anastomosis (TECA) for Hirschsprung's disease from 2 centers. METHODS: All children who underwent TECA for Hirschsprung's disease at Alder Hey Children's Hospital, Liverpool, England from January 1995 to December 1998 (n = 41) and the Children's Hospital, Helsinki, Finland from June 1988 to December 1998 (n = 95) were evaluated. Patient demographics, age at diagnosis, initial management, length of aganglionic segment, and age at operation were documented. Postoperative complications and functional outcome were analyzed. RESULTS: Patient demographics were similar in the 2 centers. Age at diagnosis was less than 1 month in 71% of children at Liverpool, compared with 53% at Helsinki. Sixteen (39%) patients in Liverpool and 75 (79%) patients in Helsinki underwent primary TECA without colostomy. Postoperative enterocolitis occurred in 14 of 136 patients (10%). An ischemic stricture of the colon was documented in 4 children in the Liverpool series, 2 of whom had TECA as a salvage procedure after a previously failed Duhamel pull-through operation. Frequency of bowel movements, seen in the immediate postoperative period in most patients gradually improved with time from a median of 5 (range, 2 to 12) bowel movements a day at 3 months after TECA to 2 (range, 1 to 6) bowel movements a day at 2 years' follow-up. Assessment of continence was possible in 51 of 136 patients (37%) over the age of 4 years. Thirty-nine children had normal bowel function giving an overall success rate of 76%. CONCLUSIONS: Transanal endorectal coloanal anastomosis is a good technique for treatment of Hirschsprung's disease with few operation-related complications. Based on the data emerging from these 2 centers the functional outcome is highly satisfactory and comparable with other established procedures.

Long-term outcome and colonic motility after the Duhamel procedure for Hirschsprung's disease.

BACKGROUND/PURPOSE: The aim of this study was to investigate long-term functional outcome and colonic motility in children who had undergone the Duhamel-type operation for Hirschsprung's disease (HSCR). METHODS: All patients (n = 91) who underwent the Duhamel or Lester Martin Modified Duhamel operation for HSCR from 1980 to 1991 were included in the study. Twenty-two healthy age-matched children were used as controls. Functional outcome was assessed by questionnaire (response rate 100%). Total and segmental colonic transit time (CTT) was determined using the saturation method (80% participation rate). RESULTS: Outcome scores were significantly worse in the study group for patients with rectosigmoid (RS, P < .001), long segment (LS, P < .001), and total colonic (TC) aganglionosis (P < .05), when compared with controls. The CTT was significantly prolonged in the RS group (P = .01) compared with LS, TC, and control groups; this was caused by prolonged "rectosigmoid" transit in the RS group compared with controls (P = .012). There was a positive linear correlation (P = .0002) between age and outcome score in patients with RS disease unrelated to CTT. Nine patients required a late long-term enterostomy. A satisfactory outcome (defined as outcome score > or = 10th percentile of the control group, and absence of stoma or requirement for major revisional surgery) was seen in only 42% of patients overall and in 79% of patients over 14 years of age. CONCLUSIONS: The Duhamel procedure, in common with other pull-through procedures, is associated with significant long-term morbidity, the aetiology of which is poorly understood.

Posterior sagittal anorectoplasty is superior to sacroperineal-sacroabdominoperineal pull-through: a long-term follow-up study in boys with high anorectal anomalies.

BACKGROUND/PURPOSE: It is unclear which surgical method offers best long-term functional results in patients with high anorectal anomalies. The purpose of this study was to compare the long-term outcome of sacroperineal-sacroabdominoperineal pull-through (SP-SAP) to that of posterior sagittal anorectoplasty (PSARP). METHODS: Only boys with high anorectal anomalies (rectourethral fistula) were included in the study to get fully comparable patient groups. From 1975 to 1987, 36 consecutive patients underwent anorectal reconstruction: 19 had SP-SAP (1975 to 1983) and 17 PSARP (12 with internal sphincter-sparing technique, 1983 to 1987). The late bowel function (age at follow up, SP-SAP, 19 years; range, 15 to 22; PSARP, 13 years; range, 10 to 19) was evaluated by clinical interview and examination, and anorectal manometry. RESULTS: Six (35%) of the PSARP patients and one (5%) of the SP-SAP patients (P < .04) were always clean without any adjunctive measures. Three PSARP patients and two SP-SAP patients stayed clean with daily enemas. In the PSARP patients with soiling, the median frequency of soiling episodes in a month was four (range, 1 to 16), in the SP-SAP patients, 20 (range, 2 to 28, P < .001). None of the SP-SAP patients but 8 of 17 of the PSARP patients had constipation requiring diet or oral medication. Two PSARP patients and four SP-SAP patients had occasional faecal accidents. The median daily bowel movements in the PSARP group was one (range, one to four) and in the SP-SAP group, three (range, one to five, P < .001). The PSARP patients had significantly higher anorectal resting and squeeze pressures and voluntary sphincter force (cm/H2O, PSARP: mean resting, 47+/-9; mean squeeze, 106+/-29; mean voluntary sphincter force, 60+/-22; SP/SAP: mean resting, 27+/-10; mean squeeze, 68+/-22; mean voluntary sphincter force, 41+/-17; P < .01). Thirteen (76%) of the 17 PSARP patients and none of SP-SAP patients had positive rectoanal reflex indicating functional internal sphincter. CONCLUSIONS: In boys with high anorectal anomalies, PSARP clearly is superior to sacroperineal and sacroabdominoperineal pull-through in terms of long-term bowel function and faecal continence.

The value of early postoperative oesophagography following repair of oesophageal atresia.

The aim of the study was to examine the relationship between anastomotic leaks and the development of symptomatic anastomotic strictures after primary repair of oesophageal atresia (OA) with or without tracheo-oesophageal fistula (TOF) and the prognostic value of the anastomotic appearance on postoperative oesophagography. The records and X-ray films of 49 patients with OA with or without TOF admitted between January 1990 and June 1995 were reviewed retrospectively. Of these, 37 had a primary repair (34 immediate and 3 delayed) and a postoperative contrast swallow was done between day 5 and day 30 (median day 7). Radiological leaks were documented. In addition, the maximum transverse diameters of the upper pouch and anastomotic region and the length of the anastomotic narrow segment were measured; the ratio of upper-pouch diameter to that of the anastomosis was calculated (anastomotic index, AI). The need for dilatation of symptomatic anastomotic strictures and for repeat dilatation as a separate episode were documented. Of the 37 patients, 4 developed an anastomotic leak (11%), 3 radiological and 1 clinical. A symptomatic stricture occurred in 55% of patients. There was no correlation between a leak and later development of a symptomatic stricture, although the small number of patients with leaks precluded definite conclusions. No radiological leak progressed to a clinical leak. There was no correlation between the AI or the length of the anastomotic narrow segment and the need for dilatation, the need for repeat dilatation, or the number of dilatations. In this study, the presence of a leak, the AI, and the length of the narrow segment on early postoperative contrast swallow did not correlate with the later development of a symptomatic stricture. A radiological leak was of no clinical significance. Since major leaks are apparent clinically, an early routine contrast study did not influence management and is not necessary.
