Robotic assisted rectopexy.

BACKGROUND: During the last 3 years, robotic surgery has had a considerable impact on minimally invasive surgery in a wide range of specialties. This study describes the surgical technique and preliminary results of our first 6 cases of robotic assisted suture rectopexy. METHODS: During a period of 13 months 6 patients with full thickness rectal prolapse were operated on with the da Vinci surgical system. All patients were considered suitable for a suture rectopexy. Setting-up time, procedure time, patient recovery, and hospital stay were recorded and compared with the current literature. RESULTS: All operations were completed successfully using the robotic system. There were no major complications and no deaths. Mean setting-up time was 28 minutes, mean operation time was 127 minutes, and mean hospital stay was 6 days. At 3 to 6 months of follow-up all patients are in good health, with no signs of recurrence and no reports of constipation. CONCLUSIONS: Robotic assisted suture rectopexy is feasible and safe and apparently meets accepted standards of laparoscopic surgery.

Management of disorders of the posterior pelvic floor.

INTRODUCTION: Constipation is a relatively common problem affecting 15 percent of adults in the Western world, and over half of these cases are related to pelvic floor disorders. This article reviews the clinical presentation and diagnostic approach to posterior pelvic floor disorders, including how to image and treat them. METHODS: A Pubmed search using keywords "rectal prolapse," "rectocele," "perineal hernia," and "anismus" was performed, and bibliographies of the revealed articles were cross-referenced to obtain a representative cross-section of the literature, both investigational studies and reviews, that are currently available on posterior pelvic floor disorders. DISCUSSION: Pelvic floor disorders can occur with or without concomitant physical anatomical defects, and there are a number of imaging modalities available to detect such abnormalities in order to decide on the appropriate course of treatment. Depending on the nature of the disorder, operative or non-operative therapy may be indicated. CONCLUSION: Correctly diagnosing pelvic floor disorders can be complex and challenging, and the various imaging modalities as well as clinical history and exam must be considered together in order to arrive at a diagnosis.

Abnormalities of function and faecal water following the modified Soave operation for Hirschsprung's disease.

Fourteen out of 18 patients (78%) had abnormal function 32 months after the modified Soave pull-through procedure for Hirschsprung's disease. The abnormalities were loose stools [9], perianal excoriation [7], soiling [11] and rectal prolapse [7]. Excoriation was caused by stools containing an excess of water, particularly in the "extractable" phase, with raised Na+ and Cl- concentrations, osmolality and hydrogen ion (pH) but normal concentration of K+. A deficiency of dry stool solid was also demonstrated. Abnormalities were most marked in patients who had high inferior mesenteric artery ligation and residual proximal left colon. Faecal water abnormalities are due to failure of complete water and electrolyte re-absorption by the pulled-through bowel. Manometric studies indicate that post-Soave patients have a small, "spastic" rectum with poor reservoir capacity which leads to soiling. Perianal excoriation occurs when faecal composition is abnormal. Four patients were improved on small doses of oral Ispaghula husk fibre. Clinical improvements were associated with alterations in stool composition.

Peutz-Jeghers syndrome in children: report of two cases and review of the literature.

In this article, we report two new cases of Peutz-Jeghers syndrome in children and review the literature over the past twenty years. This series of 70 cases demonstrates that the clinical pictures observed in children are similar to those of adults. Rectal prolapse or extrusion of polyps can be the clue to the diagnosis at an early age, even in the absence of pigmentation, which can appear later. Gastroduodenal polyps were strikingly frequent in the less than or equal to 16-yr-old group (62%) a circumstance that can create operative difficulties. Five out of the 70 patients (7.14%) had tumors during childhood (two gastrointestinal adenocarcinomas, two ovarian and one testicular neoplasms). A higher risk of tumor development in these patients does exist either as a result of degeneration of the polyps or of a genetic predisposition. Whenever operation becomes necessary, a very cautious approach must be advised in order to preserve as much intestinal length as possible in these patients, who have a lifelong disease which may require repeated operations.

Postanal repair for faecal incontinence persisting after rectopexy.

Eleven patients (nine women) with persistent faecal incontinence after rectopexy for rectal prolapse were treated by postanal repair. Follow-up data, including clinical and anorectal physiology, at 5-8 years (median 76 (range 64-95) months) were available for nine patients. At long-term follow-up, seven of the nine patients had improved continence (two were continent to solid and liquid stools, and five to solid stool). One patient required a colostomy. Median (range) physiological findings before and after postanal repair in the nine patients were: anal canal length 2.3 (1.5-3.0) versus 3.5 (2.0-5.5) cm (P < 0.05); resting anal pressure 20 (0-49) versus 35 (10-55) cmH2O (P < 0.05); perineal descent 2 (1-3) versus 0 (3 to -0.2) cm; and mean pudendal nerve terminal motor latency 2.35 (2.0-3.1) versus 2.85 (2.3-3.4) ms.

[Clinical and functional results of abdominal rectopexy using different fixation principles].

We report our results with abdominal rectopexy (modified Ripstein procedure, Ripstein/Corman) without resection of the colon in 63 patients using lyophylized dura-strips, Vicryl gauze or Dexon gauze, as the underlying fixation material for the mobilized rectum, presacral fascia and fixation suture material. Forty-five of 64 patients (71.4%) were reevaluated by proctoscopic examination and questioning; the mean follow-up time was 52.5 months (range 3-136 months). Postoperative mortality due to the method was 0%; the mortality was 1.6% (n = 1/63) in general for the first postoperative 30-day period as a result of cardiac complications. There were three complications (4.7%) the durating operation. Postoperative morbidity was 25.4% (16/63); infectious complications occurred in 12.7% (8/63) of cases, with one case of spontaneous closure of a pelvicutaneous fistula after intraoperative injury to the rectal wall. Full-thickness rectal prolapse appeared after rectopexy in 4.4% (2/45) (dura material alone) and mucosal prolapse was seen in 15.5% (7/45) of the follow-up group. Constipation was reduced by 28.6% (18/63) to 22.2% during the follow-up. Seventeen of 28 patients (60.7%) with incontinence showed an improvement; total continence was registered in 35.7% (10/28). The increase in continence as a result of abdominal rectopexy was significant (Wilcoxon, P = 0.05). The special aspects of being in an older age group, having a long history of procidentia, the number of deliveries, the length of the preoperative incontinence period all showed no influence on the postoperative degree of continence (Spearman's rank correlation). In 7/15 cases with persisting incontinence after rectopexy, postanal repair (Parks) was efficient in 7/7 cases leading to total or partial continence.(ABSTRACT TRUNCATED AT 250 WORDS)

[Laparoscopic rectopexis].

INTRODUCTION: Rektopexis is an effective treatment method of rectal prolapses. Our retrospective study assessed the laparoscopic rectopexis results. METHODOLOGY: From 01-01-2003 to 31-11-2005, 10 patients were indicated for the procedure of laparoscopic retropexis. A "Vypro" mesh (Johnson&Johnson) was used to suspend the rectum. We fix it to the sacrum and to the rectum with an anchor (Eanchr, Johnson&Johnson). The follow-up examinations were conducted 2-30 months after the procedure. We assessed mortality rates, morbidity rates, the prolaps relapses incidence rates, obstipation incidence rates. RESULTS: The laparoscopic procedure was completed in 9 patients. In one case, we converted. The mortality and serious postoperative morbidity rate was 0%. The mean duration of hospitalization was 7 days. During the follow-up, no patient relapsed. One female patient complained of mild postoperative obstipation, which, however, did not require surgical revision. CONCLUSION: Laparoscopic rectopexis is a modern, safe and effective method of the prolaps of the rectum treatment.

Severe pseudomembranous enterocolitis in a child: case report and literature review.

Antibiotic-associated pseudomembranous enterocolitis (PMC), an inflammatory gastrointestinal disease mediated by toxins produced by Clostridium difficile, is increasingly recognized in the pediatric population. We report a case of fulminant PMC in an otherwise normal 2 1/2-year-old child after antibiotic therapy given for a routine childhood illness. The patient had debilitating colitis marked by severe diarrhea, a generalized electrolyte derangement, an extreme protein-losing enteropathy state, rectal prolapse, ascites, pleural effusion, varicella and multiple relapses. The child required specific antimicrobial therapy as well as aggressive supportive care to achieve recovery. A review of the literature for pediatric cases of PMC revealed reported cases in all age groups; the youngest was 5 days old. There were 9 deaths in 43 cases for a mortality rate of about 20%. All but 2 of the cases were associated with antibiotic therapy. The antibiotics most frequently implicated were ampicillin (15), penicillin (11), cephalosporins (7), amoxicillin (6) and clindamycin (5). The onset of symptoms of PMC can begin at any time while the child is taking an antibiotic or up to 21 days after it is discontinued. Children with underlying gastrointestinal motility disorders such as Hirschsprung's disease are predisposed to PMC. Fulminant PMC is a serious but uncommon infectious disease of infancy and childhood, occurring as a complication of routine antibiotic therapy for common childhood illnesses.

Early recovery after abdominal rectopexy with multimodal rehabilitation.

PURPOSE: Abdominal rectopexy without sigmoid resection is usually associated with a hospital stay of four to ten days. Recent developments have shown that a multimodal rehabilitation program with epidural analgesia and early oral feeding and mobilization will reduce hospital stay after colonic resection. The aim of this study was to describe the results after abdominal rectopexy with a multimodal rehabilitation program. METHODS: Thirty-one consecutive patients with rectal prolapse, median age 69 (range, 24-85) years and including 14 patients of American Society of Anesthesiologists physical status III to IV, were scheduled for abdominal rectopexy with a multimodal rehabilitation program including 48 hours thoracic epidural analgesia or patient-controlled anesthesia (3 patients), early oral nutrition and mobilization, and a planned two-day postoperative hospital stay. Follow-up was done at two months postoperatively. RESULTS: All patients except one tolerated normal diet and were mobilized to the same level as before surgery on the first postoperative day. Bowel movement was reestablished at a median of Day 2, and median postoperative hospital stay was three (mean, 4.4) days. At two months follow-up 16 percent were incontinent vs. 74 percent before surgery. Constipation was noted in 43 percent before surgery vs. 28 percent at two months follow-up. CONCLUSION: Median hospital stay after abdominal rectopexy may be reduced to three days with postoperative multimodal rehabilitation.

Colorectal surgery in the elderly: an audit of surgery in octogenarians.

BACKGROUND: Morbidity and mortality rates are higher in elderly compared to younger patients undergoing colorectal cancer surgery. This study was undertaken to see whether this finding applied to all colorectal surgery in the elderly and if so to try to identify the determining factors. METHODS: All patients undergoing colorectal surgery between 1975 and 1990 were entered into a computerized database. Patients were divided into two groups, those less than 80 years (< 80) and those 80 years and more (80+), and compared with regard to the type of surgery performed, the patient's race, the seniority of the surgeon, the patient's disease, the operation performed and the postoperative morbidity and mortality. In addition, patients undergoing major resectional surgery and patients undergoing colorectal cancer surgery were compared separately. RESULTS: Of 2011 admissions, 88 were for patients of 80+. The male to female admission rate was 1:0.79 in the < 80 group and 1:1.25 in the 80+ group. More surgical procedures were performed by consultants in older patients. More emergency admissions were for 80+ patients. Rectal, sigmoid and right colonic pathology was more common in the elderly. Very few elderly patients were admitted with minor anorectal problems. Rectal prolapse and colorectal cancer were the commonest causes for admission in octogenarians. There were more pulmonary and cardiovascular postoperative complications in 80+ patients. Urinary tract infections were also more common. The postoperative mortality rate was higher in older patients (7.9 vs 1.4%). Four hundred and sixty-two patients underwent major resectional surgery and 45 were 80+. Surgery for diverticular disease was more frequent in younger patients (13.4 vs 2.2%) and cancer surgery in older patients (93.3 vs 70.5%). The postoperative mortality rate was higher in the elderly (11.1 vs 3.6%). Three hundred and thirty-six major resections were for cancer and 42 were 80+. Emergency surgery was performed more commonly in the older group (38.1 vs 14.9%). The rate of advanced disease seemed to be similar in both groups. The postoperative death rate was higher in the elderly (11.9 vs 3.4%). CONCLUSIONS: Elderly patients were more likely to die from cardiopulmonary problems after surgical interventions than either from their primary disease or from the surgery undertaken for it. Good postoperative cardiopulmonary support should thus be provided for all such patients.

How does an historic control study of a surgical procedure compare with the "gold standard"?

PURPOSE: It has been suggested that nonrandomized studies of interventions can neither discriminate between the effect of an intervention and that of bias nor accurately estimate the magnitude of measured effects. This study was designed to compare the results of an historic control study of a surgical procedure with those of a subsequent randomized control trial conducted under similar circumstances. METHODS: The results of an historic control study and a randomized, controlled trial of the safety and efficacy of laparoscopic rectopexy for rectal prolapse that were conducted 17 months apart by the same group of surgeons at the same institution were compared in terms of direction and magnitude of measured effects. RESULTS: The historic control study was reliable in determining the direction of measured effects in six of six (100 percent) outcomes common between the two studies, and there was agreement on the statistical significance (or lack of it) in five (83 percent); however, the magnitude of measured effects for all but one outcome assessed was 33 to 107 percent larger than in the randomized, controlled trial. There was no agreement in the medical literature on the effect of the historic control design on the direction and magnitude of measured effects. CONCLUSIONS: The results of a surgical historic control trial compared favorably with those of a randomized, controlled trial conducted under similar circumstances in determining the direction of measured effects but tended to yield larger estimates of effect magnitudes. The medical literature is divided on the effect of the historic control study design on study outcomes and more research is required to further define its role in evidence-based surgery.

Laparoscopic rectopexy using mesh fixation with a spiked chromium staple.

UNLABELLED: Abdominal rectopexy for patients with rectal prolapse is well suited for performance laparoscopically because no resection or anastomosis is necessary, with potential benefits being a decrease in postoperative pain, better cosmesis, and an earlier return to normal activity. PURPOSE: Objectives of this study were to determine the feasibility of laparoscopic abdominal rectopexy using a solitary spiked chromium staple to fix the mesh to the sacrum and to compare initial results with consecutive previous abdominal rectopexies (historical control study). METHODS: Duration of operation (anesthetic plus surgery), the day a solid diet was first tolerated, day of discharge, and patient morphine requirements in the first 48 hours were documented prospectively for the laparoscopic group and retrospectively from medical records for an open abdominal rectopexy group. RESULTS: Laparoscopic rectopexy group had lower morphine requirements when using patient-controlled analgesia (mean, 38.2 vs. 100.6 mg; P < 0.02), an earlier tolerance of solid diet (mean, 2.7 vs. 5.8 days; P < 0.001), and an earlier discharge from the hospital (mean, 6.3 vs. 11.0 days; P < 0.01). Operating time was longer for the laparoscopic group (mean, 198 vs. 130 minutes; P < 0.001). CONCLUSIONS: Laparoscopic rectopexy is feasible, may have benefits in reducing postoperative pain, and may aid earlier return to normal diet and activity. Given the inherent bias of a historical control study, a randomized controlled study has commenced to confirm these results.

Dynamic magnetic resonance imaging defecography: a diagnostic alternative in the assessment of pelvic floor disorders in proctology.

PURPOSE: Standard diagnostic proctologic procedures in the assessment of pelvic floor disorders include clinical evaluation and endoscopy. Particular aspects of combined pelvic floor disorders, especially those involving more than one pelvic compartment, may remain undetected without additional technical diagnostic procedures such as videoproctoscopy, cinedefecography, or colpocystodefecography. The aim of the study was to review the potentials of dynamic magnetic resonance imaging defecography to elucidate the underlying anatomic and pathophysiologic background of pelvic floor disorders in proctologic patients. PATIENTS AND METHODS: Dynamic magnetic resonance imaging defecography was performed in 20 Patients (13 females) with main diagnoses such as rectal prolapse or intussusception, rectocele, descending perineum, fecal incontinence, outlet obstruction, and dyskinetic puborectalis muscle after clinical evaluation. The investigation was performed on a 1.5 T-magnetic resonance imaging machine in supine position. The rectum was filled with Gd-DTPA enriched ultrasound gel. First a T1/T2 weighted investigation of the pelvis was performed, followed by defecography with evacuation of the rectum. Images were obtained in a sagittal plane in a frequency of 1 image/second (true FISP) at rest and during straining. The obtained magnetic resonance imaging video tapes were analyzed off-line with cinematographic evaluation of bladder base, uterus, and anal canal position in relation to the pubococcygeal line by a blinded radiologist. Investigation time was 20 minutes. RESULTS: In dynamic magnetic resonance imaging defecography of the pelvic floor, 12 patients with descending perineum, 10 rectoceles (10 females), 6 cystoceles (6 females), 4 enteroceles (4 females), 8 intussusceptions (5 females), and a dyskinetic puborectalis muscle in 3 males were detected. In 11 females and 3 males multifocal disorders were found, involving more than one compartment in females, whereas in males complex defects were restricted to the posterior compartment. Magnetic resonance imaging defecography revealed diagnoses consistent with clinical results in 77.3 percent and defects in addition to clinical diagnoses in combined pelvic floor disorders in 34 percent. CONCLUSIONS: In complex pelvic floor disorders, involving more than a single defect, dynamic magnetic resonance imaging represents a convenient diagnostic procedure in females and to a lesser extent in males, in particular in terms of dynamic imaging of pelvic floor organs during defecation. In addition to the clinical assessment, dynamic magnetic resonance imaging had clinical impact in proctologic and interdisciplinary treatment.

Laparoscopic colectomy compares favorably with colectomy by laparotomy for reduction of postoperative ileus.

PURPOSE: The aim of this study was to compare the length of postoperative ileus in patients undergoing colectomy by either laparotomy or laparoscopy. METHODS: A total of 166 patients were studied. These patients were divided into two groups: Group 1, in which colectomy was done laparoscopically, and Group 2, consisting of patients undergoing laparotomy. Both groups contained 83 patients who were matched for disease severity, indications for surgery, and procedure. Indications for surgery included sigmoid diverticulitis in 12 (14 percent) patients, polyps in 22 (27 percent), Crohn's disease in 21 (25 percent), colorectal cancer in 11 (13 percent), stoma reversal in 8 (10 percent), rectal prolapse in 3 (4 percent), and other indications in 6 (7 percent) in each group. Operations were colectomy with anastomosis (42 ileocolic, 26 colorectal, 6 colocolic, 4 ileorectal, and 2 ileal J pouch) or without anastomosis (3 abdominoperineal resections) performed by the same surgeons during the same time period January 1993 to October 1996). The nasogastric tube was removed from all patients immediately after surgery in both groups. All patients received a clear liquid diet on the first postoperative day, followed by a regular diet as tolerated. The nasogastric tube was reinserted if two or more episodes of emesis of more than 200 ml occurred in the absence of bowel movement. Patients were discharged from the hospital when tolerating a regular diet without evidence of ileus. Statistical analysis was performed using unpaired t-test and Fisher's exact probability test. RESULTS: The male-to-female ratio was 38 to 45 in both groups. A total of 10 (12 percent) and 23 (28 percent) patients in Group 1 and Group 2 had emesis (P = 0.02), and the rate of nasogastric tube reinsertion was 5 (6 percent) and 13 (16 percent), respectively (P > 0.05). There were significant differences between Groups 1 and 2 relative to the lengths of ileus (3.5 +/- 1.3 vs. 5.4 +/- 1.7 days, respectively; P < 0.001), hospitalization (6.6 +/- 3.3 vs. 8.1 +/- 2.5 days, respectively; P < 0.002), and operative time (170 +/- 60 vs. 114 +/- 46 minutes, respectively; P < 0.001). The morbidity rate was 16 (19.2 percent) and 18 (21.6 percent) in the laparoscopy and laparotomy groups, respectively. CONCLUSIONS: Although early oral intake is safe and can be tolerated by 84 percent of patients after colectomy by laparotomy, laparoscopic colectomy reduced the lengths of both postoperative ileus and hospitalization.

Rectal compliance as a routine measurement: extreme volumes have direct clinical impact and normal volumes exclude rectum as a problem.

PURPOSE: The clinical impact of rectal compliance and sensitivity measurement is not clear. The aim of this study was to measure the rectal compliance in different patient groups compared with controls and to establish the clinical effect of rectal compliance. METHODS: Anorectal function tests were performed in 974 consecutive patients (284 men). Normal values were obtained from 24 controls. Rectal compliance measurement was performed by filling a latex rectal balloon with water at a rate of 60 ml per minute. Volume and intraballoon pressure were measured. Volume and pressure at three sensitivity thresholds were recorded for analysis: first sensation, urge, and maximal toleration. At maximal toleration, the rectal compliance (volume/pressure) was calculated. Proctoscopy, anal manometry, anal mucosal sensitivity, and anal endosonography were also performed as part of our anorectal function tests. RESULTS: No effect of age or gender was observed in either controls or patients. Patients with fecal incontinence had a higher volume at first sensation and a higher pressure at maximal toleration (P = 0.03), the presence of a sphincter defect or low or normal anal pressures made no difference. Patients with constipation had a larger volume at first sensation and urge (P < 0.0001 and P < 0.01). Patients with a rectocele had a larger volume at first sensation (P = 0.004). Patients with rectal prolapse did not differ from controls; after rectopexy, rectal compliance decreased (P < 0.0003). Patients with inflammatory bowel disease had a lower rectal compliance, most pronounced in active proctitis (P = 0.003). Patients with ileoanal pouches also had a lower compliance (P < 0.0001). In the 17 patients where a maximal toleration volume < 60 ml was found, 11 had complaints of fecal incontinence, and 6 had a stoma. In 31 patients a maximal toleration volume between 60 and 100 ml was found; 12 patients had complaints of fecal incontinence, and 6 had a stoma. Proctitis or pouchitis was the main cause for a small compliance. All 29 patients who had a maximal toleration volume > 500 ml had complaints of constipation. No correlation between rectal and anal mucosal sensitivity was found. CONCLUSION: Rectal compliance measurement with a latex balloon is easily feasible. In this series of 974 patients, some patient groups showed an abnormal rectal visceral sensitivity and compliance, but there was an overlap with controls. Rectal compliance measurement gave a good clinical impression about the contribution of the rectum to the anorectal problem. Patients with proctitis and pouchitis had the smallest rectal compliance. A maximal toleration volume < 60 ml always led to fecal incontinence, and stomas should be considered for such patients. A maximal toleration volume > 500 ml was only seen in constipated patients, and therapy should be given to prevent further damage to the pelvic floor. Values close to or within the normal range rule out the rectum as an important factor in the anorectal problem of the patient.

Eroded polypoid hyperplasia of the rectosigmoid.

We studied histologic sections and clinical data from six patients with multiple rectosigmoid polyps that could not be readily classified. Features common to all were: 1) numerous polyps restricted to the rectosigmoid colon without evidence of polyposis or gastrointestinal disease elsewhere, 2) severe clinical symptoms mimicking inflammatory bowel disease, 3) no family history of polyposis or evidence of infection and 4) histology showing minimally inflamed polypoid hyperplastic mucosa with surface erosions or pseudomembranes. Three patients underwent colectomies; three showed a response to oral steroids. One had rectal prolapse. Although reminiscent of inflammatory cloacogenic polyps or solitary rectal ulcer syndrome, the polyps extended into the sigmoid colon, were quite numerous, and showed only mild smooth muscle insinuation in the lamina propria. Whether these lesions are due to occult prolapse or are an unusual manifestation of inflammatory bowel disease remains unclear.
