Longitudinal multiple rubber band ligation: an alternative method to treat mucosal prolapse of the anterior rectal wall.

PURPOSE: The aim of this study is to present a new approach for the treatment of mucosal prolapse of the anterior rectal wall using a multiple longitudinal rubber band ligation procedure. METHODS: The therapeutic approach using multiple longitudinal rubber band ligations on anterior rectal wall was undertaken in 17 patients after failure of conventional medical treatment. RESULTS: Double rubber band ligation was undertaken in seven patients and triple ligation in nine patients. In a median follow up of 12 months fourteen patients (87.5 percent) showed complete and persistent remission of symptoms. Two patients remained symptomatic and were treated by a second session of rubber band ligation which was successful in one of them. No complications occurred in this present series except in one patient with internal rectal prolapse patient who complained of persistent pain for seven days. CONCLUSIONS: These encouraging results have suggested this method as an effective alternative in the relief of this usually very symptomatic disorder.

Treatment of incontinence in children with bladder exstrophy after rectal urinary diversion: the anal sling procedure.

PURPOSE: An original technique for reinforcement of the anal sphincter using a sling prosthesis with a flexible fixing point that prevents incontinence and rectal prolapse is presented. MATERIALS AND METHODS: Of 43 patients with exstrophy who have undergone urinary rectal diversion between 1988 and 1997 incontinence was observed in 9 boys and 5 girls. From January 1993 to December 1998 these children were treated with an original method, the anal sling procedure. RESULTS: There were no postoperative complications. Investigations revealed no urinary or fecal incontinence after a mean followup of 3.2 years (range 6 months to 61/2 years). CONCLUSIONS: A short and simple operation eliminates incontinence after rectal urinary diversion in patients with bladder exstrophy. It can be used as an alternative to the formation of an isolated urinary reservoir.

Results of neurophysiologic evaluation in fecal incontinence.

PURPOSE: Several methods of neurophysiologic assessment exist in the investigation of patients with fecal incontinence. However, the clinical significance of the information gained is uncertain. The aim of this prospective study was to evaluate the results of pudendal nerve terminal motor latency and fiber density in relation to clinical variables and manometric measurements. METHODS: Seventy-two patients with fecal incontinence (63 women; mean age, 62; range, 24-81 years) responded to a bowel questionnaire and underwent anorectal manovolumetry, anal ultrasonography, defecography, and electromyography, including pudendal nerve terminal motor latency and fiber density. RESULTS: Pudendal neuropathy (pudendal nerve terminal motor latency > 2.5 ms) was found in 46 percent and increased fiber density (> 1.7) in 82 percent. Pudendal neuropathy and increased fiber density were most common in patients with rectal prolapse or intra-anal intussusception. No difference was seen concerning anal resting and incremental pressures, rectal compliance, rectal sensibility or severity of incontinence in patients with unilateral, bilateral, or marked (> 4 ms) pudendal neuropathy vs. patients with normal pudendal nerve terminal motor latency. In contrast, patients with increased fiber density had lower incremental pressures (P < 0.05) and stated decreased rectal sensibility (P < 0.05) compared with those with normal fiber density. These differences were most pronounced in patients with neurogenic or idiopathic incontinence. CONCLUSIONS: Pudendal neuropathy and increased fiber density are common in patients with fecal incontinence. Fiber density but not pudendal nerve terminal motor latency was correlated with clinical and manometric variables. The severity of nerve injury correlated with anal motor and sensory function in patients with neurogenic or idiopathic incontinence. The routine use of pudendal nerve terminal motor latency in the assessment of patients with fecal incontinence can be questioned.

A laparoscopic pull-through operation for Hirschsprung's disease: report of two infant cases.

We describe herein a primary laparoscopic pull-through procedure that was successfully employed to treat two infants with Hirschsprung's disease. Mobilization of the rectum and sigmoid colon was performed laparoscopically, and the rectal mucosa was removed via a transanal submucosal resection. After inducing the rectal prolapse intussusceptically, the rectum was circumferentially transected, and the mobilized colon was pulled down through the rectal muscle cuff. Resection of the aganglionic bowel and the coloanal anastomosis, using the Soave-Denda method, was performed outside the anus. Both infants had an uneventful postoperative course with early recovery of bowel movement. Our experience demonstrates that this minimally invasive surgical procedure is feasible for young infants, and we believe that Hirschsprung's disease may be a definite indication for laparoscopic surgery.

Rectal intussusception: a study of rectal biomechanics and visceroperception.

OBJECTIVES: Rectal intussusception (RI) is a significant cause of morbidity amongst those with a rectal evacuatory disorder. The pathophysiology is unknown, but may involve abnormal biomechanics of the rectal wall similar to that previously demonstrated in patients with overt rectal prolapse (RP). Using an electromechanical barostat, this study aimed to investigate the biomechanics and visceroperception of the rectal wall in patients with RI. METHODS: Twenty consecutive patients (12 females, median age 46 yr (range 24-66)) with symptomatic, full-thickness RI were studied. Patients underwent assessment of rectal compliance, visceroperception, adaptive response to isobaric distension at urge threshold, and assessment of the postprandial response. Results were compared with those obtained in 28 asymptomatic volunteers, 10 with RI (6 females, median age 29 yr (range 21-36)) and 18 (9 females, median age 33 yr (range 21-62)) without. RESULTS: In the absence of the clinical finding of solitary rectal ulcer syndrome (SRUS), patients with symptomatic RI have normal rectal wall biomechanics, as do asymptomatic volunteers with RI (p < 0.05). Patients with the clinical finding of SRUS had reduced compliance and adaptation. In all three groups, there was a linear relationship between rectal pressure and visceroperception. The postprandial contractile response was similar between groups. CONCLUSIONS: Patients with RI have normal rectal wall biomechanics. This is in contrast to patients with RP, and suggests that while they may represent different stages of the same disease process, they are physiologically distinct. In patients with RI and SRUS, rectal wall inflammation and fibrosis, perhaps arising secondary to the intussusception, may explain the physiological changes observed.

Feasibility of colectomy with mini-incision.

BACKGROUND: Laparoscopic resection has been advocated as a method of colectomy for various colon and rectal disease. One advantage claimed by laparoscopy is its smaller incision size. The aim of the present study is to evaluate whether mini-incision is feasible along with the advantage of adequate exploration of the peritoneal cavity. METHODS: From December 2000 to November 2003, 316 patients with various colorectal diseases receiving colectomies through a skin incision less than 7 cm were analyzed. All of the colectomies were performed by a single surgeon. Exploration of the entire peritoneal cavity was possible for all the cases. There were 153 men and 163 women. Ages ranged from 19 to 90 years, averaging 62.4 years. Two hundred ninety-five patients were operated on for carcinoma of the colon or rectum; 4 had operations for villous tumors with severe dysplasia; 3 each for radiation enterocolitis and diverticulitis; 2 each for malignant stromal tumor and rectal prolapse; and 1 each for lymphoma, actinomycosis, volvulus, angiodysplasia, Crohn's disease, ulcerative colitis, and ovarian cancer with rectal invasion. There were 15 abdominoperineal resections, 97 low anterior resection, 49 anterior resections, 64 sigmoidectomies, 7 left hemicolectomies, 81 right hemicolectomies, 2 subtotal colectomies, and 1 restorative proctocolectomy. No Harmonic scalpel or laser was used during surgery. No hand-port or laparoscope was used in the series. RESULTS: Five patients died of acute respiratory failure, 2 patients died of terminal cancer, and 1 patient died of hypoglycemia due to poor control of diabetes mellitus. Complications included 11 urinary tract infections, 8 intestinal obstructions, 6 anastomotic leakages, 6 wound infections, 5 respiratory failures, 5 pelvic bleedings, 2 pneumonias, 2 gastrointestinal bleedings, and 1 pancreatitis. Small incisions did not prolong operation time. CONCLUSION: This experience suggests that the majority of colectomies can be accomplished by an incision of less than 7 cm, which is no larger than the incision size used in a laparoscope colectomy if multiple incisions made for trocars are added to the main incision length. The advantages of mini-incision include lower cost, faster completion of procedure, reduced bulkiness of equipment, and the possibility of exploring the entire peritoneal cavity by hand without loss of tactile sensation.

Solitary rectal ulcer: the place of biofeedback and surgery in the treatment of the syndrome.

Thirty-one patients with the solitary rectal ulcer syndrome were studied, the majority of whom presented with fresh blood per rectum and a rectal ulcer, mucorrhoea, or a varying degree of rectal prolapse. Fourteen patients were treated conservatively or with surgery and had a high rate of recurrence of the solitary rectal ulcer syndrome. Seventeen patients were treated with biofeedback for the associated obstructed defecation (anismus) either before or immediately after surgery with a lower recurrence rate. The final symptomatic cure rate was similar in both groups but 15 episodes of recurrence requiring further surgery were encountered in the non-biofeedback group compared to 4 recurrences in the biofeedback group.

Rectal hypersensitivity worsens stool frequency, urgency, and lifestyle in patients with urge fecal incontinence.

PURPOSE: Rectal sensory mechanisms are important in the maintenance of fecal continence. Approximately 50 percent of patients with urge incontinence have lowered rectal sensory threshold volumes (rectal hypersensitivity) on balloon distention. Rectal hypersensitivity may underlie the heightened perception of rectal filling; however, its impact on fecal urgency and incontinence is unknown. This study was designed to investigate the impact of rectal hypersensitivity in patients with urge fecal incontinence. METHODS: Prospective and retrospective audit review of all patients (n = 258) with an intact native rectum referred to a tertiary colorectal surgical center for physiologic investigation of urge fecal incontinence during a 7.5-year period. Patients with urge fecal incontinence who had undergone pelvic radiotherapy (n = 9) or rectal prolapse (n = 6) were excluded. RESULTS: A total of 108 of 243 patients (44 percent) were found to have rectal hypersensitivity. The incidence of anal sphincter dysfunction was equal (90 percent) among those with or without rectal hypersensitivity. Patients with urge fecal incontinence and rectal hypersensitivity had increased stool frequency (P < 0.0001), reported greater use of pads (P = 0.003), and lifestyle restrictions (P = 0.0007) compared with those with normal rectal sensation, but had similar frequencies of incontinent episodes. CONCLUSIONS: Urge fecal incontinence relates primarily to external anal sphincter dysfunction, but in patients with urge fecal incontinence, rectal hypersensitivity exacerbates fecal urgency, and this should be considered in the management and surgical decision in patients who present with fecal incontinence.

A rare and often unrecognized cause of hematochezia and tenesmus in childhood: solitary rectal ulcer syndrome.

Solitary rectal ulcer syndrome (SRUS) is an unusual disorder of childhood, which usually presents with rectal bleeding, mucous discharge, prolonged straining, tenesmus, and localized pain in the perineal area. After the first description by Cruveilhier, Madigan and Morson further detailed the clinical and pathologic features of SRUS in 1969. The pathogenesis of the syndrome is not well-understood. The postulated mechanism responsible for rectal prolapse in most cases seems to be excessive straining efforts during which high intra-abdominal pressure forces the anterior rectal mucosa firmly into the contracting puborectalis muscle. The anterior rectal mucosa is frequently forced into the anal canal and as a consequence becomes strangulated, causing congestion, edema, and ulceration. Histologically, the presence of fibromuscular obliteration of the lamina propria with disorientation of muscle fibers is characteristic, which could be secondary to chronic mechanical and ischemic trauma and inflammation by hard stools, and intussusception of the rectal mucosa. Although the syndrome is well-recognized in adults, the pediatric experience with this condition is limited and often remains unrecognized or misdiagnosed. A misdiagnosis has been reported in one fourth of adult cases, and the correct diagnosis usually delayed approximately 5 to 7 years. There are few pediatric case reports in English literature. Here, we describe 2 children with SRUS, aged 11 and 14 years, whose SRUS was diagnosed 2 and 6 years, respectively, after the onset of the first signs and symptoms.

Traumatic solitary rectal ulcer in Saudi Arabia. A distinct entity?

Solitary rectal ulcer syndrome is a perplexing condition with a complex multifactorial pathophysiology. Inappropriate contraction of the puborectalis muscle and rectal mucosal prolapse have been commonly implicated, although self-induced trauma has been suspected in some cases. Eight patients who presented with rectal bleeding with excessive mucus were found to have an isolated rectal ulcer on proctosigmoidoscopy. Constipation, straining at stools, and pain in the anal region were present in seven of eight cases. All of them confessed to rectal digitation. Most of them had consulted more than two physicians and half of them had had barium enema and colonoscopy in the past. An ulcer was present on the anterior wall at 6-8 cm from the anal verge in seven of eight patients and none of them had either external or internal rectal prolapse. Rectal biopsy performed in six of eight showed histological findings consistent with the diagnosis of solitary rectal ulcer. Patients were convinced to stop finger evacuation and were given psyllium supplements. There was endoscopic healing with symptomatic improvement in the six patients who followed up for an average period of 38 weeks. We conclude that traumatic solitary rectal ulcer due to rectal digitation is a distinct entity and response to avoidance of this habit is good.

Juvenile polyposis.

Juvenile polyposis is an uncommon condition characterized by the development of multiple juvenile polyps, predominantly in the colon but also in the rest of the gastrointestinal tract. The condition usually presents in childhood; only 15 per cent of patients present as adults. The rarer and often fatal form, namely, juvenile polyposis of infancy, is typified by diarrhoea, protein-losing enteropathy, bleeding and rectal prolapse. The more common form of juvenile polyposis (affecting the colon, stomach and small bowel) occurs in the first or second decade with rectal bleeding and anaemia. A family history of the condition is found in 20-50 per cent of patients with apparently an autosomal dominant trait. The gene for juvenile polyposis has not yet been identified. Epithelial dysplasia is common and the cumulative risk of colorectal cancer is > 50 per cent. Various extracolonic abnormalities may also occur. Most patients are treated surgically for colonic polyps, although endoscopic polypectomy is also an option. The rest of the gastrointestinal tract should be screened as should asymptomatic first-degree relatives.

Revision anorectoplasty in the management of anorectal anomalies.

Twelve patients who had a revision posterior sagittal anorectoplasty (PSARP) were evaluated by questionnaire. They were 11 months to 15 years old (median 5 years) at the time of revision surgery. All were born with an intermediate to high anorectal anomaly (ARM) and had ongoing problems of rectal prolapse (3), stenosis (1), faecal incontinence (9), or severe constipation (4). All but 1 had a huge megarectum with a poor anorectal angle and stool impaction, causing overflow incontinence. After revision surgery, marked improvement occurred in 7 and at least some improvement was achieved in the remaining 5. Previous severe constipation resolved in 2 and improved in another 2 children. The number of soiling episodes significantly decreased in 8 patients: while before surgery 8 had been wearing nappies all the time, only 2 use them postoperatively. The anorectal prolapse has resolved in 3 and sensation improved in 5, and as a group, there has been a reduced need for laxatives and rectal washouts. The favourable outcome of our patients confirms that PSARP is an excellent technique for revision surgery, and tapering of a secondary megarectum plus the formation of an anorectal angle can produce clinical improvement, even in more severe forms of ARM.

Juvenile polyposis of the colon: sonographic diagnosis.

Juvenile polyposis is an uncommon condition characterized by development of multiple juvenile polyps, predominantly in the colon but also in the rest of the gastrointestinal tract. The condition usually appears in childhood. The rarer and often fatal form, occurring in infancy, is typified by diarrhea, protein-losing enteropathy, bleeding, and rectal prolapse. The more common form of juvenile polyposis (affecting the colon, stomach, and small bowel) occurs in the first or second decade with rectal bleeding and anemia. We report a case of juvenile polyposis detected on sonography, which had been treated as severe anemia for 1 year.

Reoperation for Hirschsprung's disease.

BACKGROUND/PURPOSE: Reoperation for Hirschsprung's disease traditionally has been used for patients with anastomotic leaks or stricture or with severe constipation from retained aganglionic segment or neuronal dysplasia, but there is little information regarding its use for other complications and the long-term outcome in these patients. METHODS: In a 23-year period, 107 infants and children underwent Soave (68 patients) or Duhamel (39 patients) pull-through procedures. The age at operation was newborn to 6 years (mean, 10 months). Eighty percent had aganglionosis limited to the rectosigmoid colon. Follow-up was by office visit or telephone (mean, 8.5 years). RESULTS: Twenty-three of the 68 patients with Soave pull-through (34%) underwent reoperation for intractable enterocolitis (10 patients, all 10 cured); anastomotic stenosis (four patients, three cured, one continued diversion); anastomotic leak (four patients, four cured); retained aganglionic segment (three patients, three cured); one necrosis of pull-through converted to Duhamel and cured; and one rectal prolapse that was diverted. Fifteen of the 39 patients with Duhamel procedure (38%) underwent reoperation for severe constipation (seven patients, six cured, one diverted); persistent rectal septum (four patients, 4 cured); and intractable enterocolitis (four patients, three cured, one diverted). Overall, 21 of 23 patients (91%) with reoperation after Soave procedures were cured, whereas 13 of 15 patients (87%) who underwent reoperation after Duhamel procedure were cured, and four patients remain diverted. CONCLUSIONS: These data show that aggressive reoperation can result in a high cure rate in Hirschsprung's disease. Although there is no significant difference in the rate of reoperation after Duhamel and Soave procedures, the patients with Soave pull-through required more complex reoperations, with several requiring more than one procedure. An aggressive approach to reoperation in patients with Hirschsprung's disease clearly is justified.

[Diagnostic and therapeutic procedures in fecal incontinence in general practice of the surgically educated proctologist].

Age related, about 10% of the general population suffer from faecal incontinence. In a surgical, proctological office diagnosis is possible with carefully taken history, physical examination, digital examination of the anorectum, rigid rectosigmoidoscopy, and anoscopy. Together with special examinations (endoanal ultrasound, electromyography, pudendal nerve terminal motor latency [PNTML], anorectal manometry, defaecography, transit time of the colon) the plan for medical and surgical treatment can be made. The basic medical conservative therapy consists of regulating the form of stool (high fibre diet and/or loperamid), training of the sphincter and pelvic muscles electrical stimulation or biofeedback training. Outpatient surgery is possible for small prolapsing tumors of the lower rectum or anal canal, hemorrhoids grade 2 or segmental anal prolapse. Inpatient surgery is needed for any form of reconstruction of the sphincter or the sensitive area of the anal canal, post- and preanal repair, anal and rectal prolapse, (dynamic) gracilis sphincteroplasty, or for a terminal stoma in those patients, whose uncontrolled incontinence cannot be managed otherwise. After surgery it is needed to continue the medical therapy (regulating the bowel movements, biofeedback training, electrical stimulation of the sphincter).

Special anoscope for easy purse-string suture application in stapled hemorrhoidopexy.

BACKGROUND: Internal hemorrhoids and loose rectal mucosa may block exposure during the purse-string suturing in stapled hemorrhoidopexy, and this may lead to complications. MATERIALS AND METHODS: To retract the prolapsing rectal mucosa, we modified the purse-string anoscope of the PPH01 kit (Ethicon-Endosurgery, Cincinnati, OH, USA) and produced a special anoscope. The open part of the purse-string suture anoscope is covered by transparent acrylic (Orthoacryl, Dentaurum, Pforzheim, Germany). The covering had completely cylindrical outer and inner surfaces and was thin enough to let the anoscope easily rotate in the anal dilator and to let the 26 mm curved, round-bodied needle of the 2/0 polypropylene suture move in the anoscope. A window, 3 cm long and 3-4 mm wide, was opened at the angled part of the anoscope 2 cm to the tip. This special anoscope was used for the purse-string suture during the stapled hemorrhoidopexy procedure in five patients. RESULTS AND CONCLUSIONS: No postoperative complications, early or late, were encountered, and we propose that stapled hemorrhoidopexy procedure can be applied more easily by using this special anoscope.

[Biofeedback and surgery in the treatment of fecal incontinence and lesion of the external anal sphincter: long-term follow-up].

INTRODUCTION: In children, damage in the anal area which affects both the external anal sphincter and the internal anal sphincter is serious problem. Biofeedback is not effective if the external anal sphincter is severely damaged, and surgery by itself cannot effect a cure for incontinence in these cases. CLINICAL CASE: a girl aged 6 yrs 8 months who from the age of two suffered from massive recurrent tricolephalosis, causing rectal prolapse, anal abscesses and fistulas, fistulectomy, and finally severe damage in the anal area with total incontinence. The treatment began with recto-anal manometry, and rectal sensitivity studies. Biofeedback was used before and after gracilis muscle transfer and colostomy. After 12 months, total continence was achieved, and has continued through 7 years of follow-up examinations. CONCLUSIONS: To treat fecal incontinence combined with severe damage in the external anal sphincter, the following procedure should be followed: manometry and sensitivity studies, reconstruction of the external anal sphincter with gracilis muscle transfer, and biofeedback.
