Effect of restorative proctocolectomy on gastric acid secretion and serum gastrin levels: a prospective study.

PURPOSE: The aim of the present study was to analyze gastric acid secretion after restorative proctocolectomy, because it has been shown that ileal resection or exclusion may increase gastric acid secretion. An increased output of gastric acids may decrease the intestinal passage time and contribute to looser stools. METHODS: Eleven patients who had elective colectomy and ileoanal pouch because of ulcerative colitis were investigated. Eight patient were males. Eight S-pouches and three J-pouches were constructed. Gastric acid secretion (retention, basic, and stimulated) was studied, together with serum gastrin, pentagastrin, and pepsinogen, in patients before colectomy and after having had the pelvic pouch functioning for 12 months. RESULTS: A significant increase, compared with preoperative levels, in retention, basic, and stimulated gastric acid secretion was found after 12 months with the pouch functioning. Levels of serum gastrin, pentagastrin, and pepsinogen were unchanged. CONCLUSION: Restorative proctocolectomy leads to a significant increase in gastric acid secretion. These findings may be of importance with regard to intestinal passage time and consistency of the stools.

A new look at the anal transitional zone with reference to restorative proctocolectomy and the columnar cuff.

BACKGROUND: The anal transitional zone (ATZ) is of interest in relation to anorectal function and its fate during the operation of restorative proctocolectomy. There are only a few studies describing the anatomy of this structure. This study applied new techniques to quantify the ATZ in normal and inflammatory bowel disease states. METHODS: The epithelial linings of 28 anal canals were analysed by two techniques: whole-mount Alcian blue staining and a new method of creating a computer map of the histological findings based on longitudinal sections taken every 3 mm. The Alcian blue pictures and the histology maps were measured and compared using image analysis software. RESULTS: The ATZ usually commences just above the dentate line, which is situated a median of 1.05 cm above the lower border of the internal sphincter. The median length of the ATZ measured from computer maps of the histology was 0.45 cm. This was significantly smaller than the 0.73 cm obtained by the Alcian blue technique, which overestimates the length of the ATZ. The amount of columnar epithelium in the ATZ is very small. The median lowest point of columnar epithelium in the anal canal was 1.1 cm above the lower border of the internal sphincter. CONCLUSION: The ATZ is only half the length described previously. After double-stapled restorative proctocolectomy there is a 1.5-2.0-cm cuff of diseased columnar epithelium remaining in the upper anal canal above the ATZ. This is suitably termed the 'columnar cuff' and is an important consideration in long-term follow-up.

Hand-assisted laparoscopic versus open restorative proctocolectomy with ileal pouch anal anastomosis: a randomized trial.

OBJECTIVE: The aim of the study was to evaluate postoperative recovery after hand-assisted laparoscopic or open restorative proctocolectomy with ileal pouch anal anastomosis for ulcerative colitis and familial adenomatous polyposis in a randomized controlled trial. METHODS: Sixty patients were randomized for hand-assisted laparoscopic (n = 30) or open surgery (n = 30). Primary outcome parameter was postoperative recovery in the 3 months after surgery, measured by quality of life questionnaires (SF-36 and GIQLI). Secondary parameters were postoperative morphine requirement and surgical parameters, viz. operating time, morbidity, hospital stay, and costs. RESULTS: There was no difference between the 2 procedures in quality of life assessment in the 3 months after surgery. There was a significant decline in quality of life on all scales of the SF-36 (P < 0.001) and total GIQLI score (P < 0.001) in the first 2 weeks in both groups (no significant difference between the groups). Quality of life returned to baseline levels after 4 weeks. Operating times were longer in the laparoscopic group compared with the open group (210 and 133 minutes, respectively; P < 0.001). No significant differences were found in morphine requirement. Neither morbidity nor postoperative hospital stay differed between the laparoscopic and open group (20% versus 17%, in 10 versus 11 days, respectively). Median overall costs were 16.728 for the hand-assisted laparoscopic procedure and 13.406 for the open procedure (P = 0.095). CONCLUSIONS: Recovery measured using quality of life questionnaires is comparable for hand-assisted laparoscopic or open restorative proctocolectomy with ileal pouch anal anastomosis. The laparoscopic approach is as safe, but more costly than the open procedure.

Laparoscopic restorative proctocolectomy for patients with ulcerative colitis.

BACKGROUND: Significant concern continues about the feasibility of laparoscopic restorative proctocolectomy (RP) with an ileal J pouch anal anastomosis in the surgical treatment of patients with ulcerative colitis (UC). The aim of this study was to clarify the feasibility of laparoscopic RP at a single institution where the surgical routine of laparoscopic colorectal surgery has already been established. PATIENTS AND METHODS: Between July 1994 and December 2001, 18 patients with UC underwent laparoscopic RP. The median age was 30 (range, 18-51) years, and the median follow-up was 20 (range, 5-89) months. Five trocars were placed. After the entire colon and rectum were mobilized and the vessels were divided intracorporeally, the rectum was divided with use of a laparoscopic linear stapler. A pouch anal anastomosis was fashioned with use of a double stapling technique. A diverting loop ileostomy was fashioned. RESULTS: There were no conversions to the open procedure. The median operative time and median blood loss were 360 (range, 290-500) minutes and 105 (range, 10-586) mL, respectively. Six postoperative complications occurred (wound sepsis, 2; bowel obstruction, 1; anastomotic stricture, 2; pouchitis, 1). In one patient, a bowel obstruction developed 3 months after the operation, which was managed conservatively. The median length of the hospital stay was 9 (range, 7-21) days. CONCLUSIONS: The laparoscopic RP is safe and feasible in selected patients with UC. New laparoscopic instrumentation, such as a linear stapler, and a more reliable laparoscopic coagulating and dividing tool should be designed, which would make it possible to perform this procedure more frequently in the surgical treatment of UC.

Results after restorative proctocolectomy and ileal pouch-anal anastomosis in patients with familial adenomatous polyposis and coexisting colorectal cancer.

Although the operation of choice for patients with familial adenomatous polyposis (FAP) is restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA), its place in the management of patients with FAP and cancer has not been defined. The authors have reviewed their experience with these patients to determine the safety of IPAA and its efficacy as a cancer operation. The records of 55 patients with FAP who had undergone IPAA were examined. Follow-up studies included an annual questionnaire and physical examination. Eight patients had FAP with coexisting colorectal cancer. Median age at diagnosis was 25 (range 13-46) years, and at operation 33 (range 22-36) years. Of the eight patients (four men), four had colonic cancer and four had rectal cancer. Synchronous colorectal carcinoma was found in two patients. Staging according to the tumor node metastasis classification showed that five patients had stage 1 tumour, two had stage 2 and one had stage 3. Tumours were well, moderately or poorly differentiated in one, five and two patients respectively. During a median follow-up of 56 (range 14-98) months, metastasis developed in the liver of one patient 66 months after surgery. Two patients suffered complications: one had small bowel obstruction and the other mucosal prolapse. Tubular adenomas were found in the pouch of two patients and in the anal transitional zone of one. Pouch function is good to excellent in all surviving patients. Restorative proctocolectomy for patients with FAP and coexisting colorectal cancer can be undertaken with a favourable prognosis and function. It is compatible with curative intent.

Restorative proctocolectomy with ileal pouch-anal anastomosis in very young patients with refractory ulcerative colitis.

BACKGROUND/PURPOSE: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the standard surgical treatment for ulcerative colitis (UC). The purpose of the current study was to determine the outcome of very young patients (< or =10 years of age) with UC undergoing IPAA. METHODS: Between 1978 and 2002, 13 patients 10 years of age or younger underwent IPAA for management of UC at the authors' institution. Charts were reviewed for patient characteristics, and a standardized telephone interview was performed. RESULTS: Average age at diagnosis was 4.0 years (range, 1.0 to 8.4 years), and patients underwent IPAA at a mean of 6.8 years (range, 3.7 to 10.8 years). Pancolitis was present in 100%. The mean follow-up was 9.1 years (1.0 to 16.1 years), the average number of stools per day was 5 (3 to 8). All patients are continent while awake. Pouchitis was documented in 9 patients (75%). All patients or their parents rated the outcome of their procedures as "excellent." CONCLUSIONS: When compared with older children, very young patients with UC tend to have more frequent total colonic involvement and a greater frequency of pouchitis after IPAA. The functional outcome and patient/family satisfaction with the procedure endorse IPAA as an attractive procedure even in the very young population with UC.

Pre-pouch ileitis: a disease of the ileum in ulcerative colitis after restorative proctocolectomy.

OBJECTIVE: Ileal inflammation in ulcerative colitis can occur as backwash ileitis or prestomal ileitis. After restorative proctocolectomy (RPC), ileal inflammation may be present in the pouch (pouchitis) but inflammation proximal to the pouch in the neo-terminal ileum, so called pre-pouch ileitis (PI), has also been observed. As pouchitis is increasingly common and PI can mimic it, our aim was to characterize this condition. SUBJECTS AND METHODS: A review of prospectively collected data on 571 inflammatory bowel disease patients undergoing follow-up after RPC in a single centre over 22 years was performed. The histology of biopsy material was reviewed and staining for colonic mucosal phenotypic changes was undertaken. It was not routine practice to prospectively assess all patients for pre-pouch ileitis when the database was constructed. RESULTS: Of 19 patients with inflammation of the pre-pouch neo-terminal ileum (NTI) identified three had Crohn's disease and one a NSAID stricture. The remaining 15 had a characteristic diffuse inflammation extending from the NTI-pouch junction proximally: pre-pouch ileitis. The inflammation extended proximally for up to 50 cm. Fistula formation was seen in only one. Seven (47%) of 15 had pouchitis but only two had suffered backwash ileitis pre-operatively. Seven responded to medical therapy and four to surgery. The histological appearances including staining for colonic phenotypic change were similar in PI and pouchitis. CONCLUSION: Pre-pouch ileitis is uncommon. As the patients' previous diagnosis of UC was confirmed and there was no radiological or histological evidence of Crohn's disease, PI appears to have a distinct pathogenesis from Crohn's disease.

Outcome of restorative proctocolectomy when the diagnosis is suggestive of Crohn's disease.

Twenty of 81 patients treated by restorative proctocolectomy for presumed ulcerative colitis had some features of Crohn's disease: 10 were classified as definite Crohn's disease and 10 as indeterminate colitis. These pathological features were first apparent during synchronous colectomy and pouch construction in 10 of 11 cases. In the remainder, histological features of possible Crohn's disease were first identified during rectal excision (n = 6), preliminary subtotal colectomy (n = 2), and after pouch excision (= 2). Complications were marginally more common in patients with features of possible Crohn's disease: pelvic sepsis 30% (Crohn's disease 30%, indeterminate colitis 30%) v 20%, fistulas 45% (Crohn's disease 30%, indeterminate colitis 60%) v 16%; ileal stenosis 40% (Crohn's disease 40%, indeterminate colitis 40%) v 21%, pouchitis 50% (Crohn's disease 50%, indeterminate colitis 50%) v 26%, and small bowel obstruction 25% (Crohn's disease 30%, indeterminate colitis 30%) v 13%. Pouch excision or a persistent proximal stoma has been necessary in six patients with possible Crohn's disease (30%) (Crohn's disease 3 cases 30%, indeterminate colitis 3 cases 30%) compared with nine (15%) of the remainder. Median hospital stay, however, was the same and stool frequency in those with a functioning pouch were comparable. These results show that there is a higher complication rate if there are features of Crohn's disease but that the medium term functional results are acceptable if the pouch can be retained.

Pouch-anal cancer after restorative proctocolectomy for familial adenomatous polyposis.

Familial adenomatous polyposis (FAP) and idiopathic ulcerative colitis are both mucosal diseases that bear a significant risk of developing colorectal cancer. As a consequence, their surgical treatment is currently widely performed by restorative proctocolectomy with pelvic ileal pouch-anal anastomosis (IPAA). Herein we report a new case of cancer after IPAA that developed in a 33-year-old woman with FAP. Pouch-anal cancer was diagnosed 8 years after restorative proctocolectomy, including anorectal mucosectomy, for FAP with manifest cancer in the sigmoid colon. This case observation reemphasizes that the risk of cancer for FAP patients persists as long as any rectal mucosa remains after IPAA surgery.

Three cases of adenocarcinoma following restorative proctocolectomy with hand-sewn anastomosis for ulcerative colitis: a review of reported cases in the literature.

Restorative proctocolectomy (RPC) has been accepted as optimal surgical therapy for most patients with ulcerative colitis. The occurrence of adenocarcinoma adjacent to the ileoanal anastomotic site for ulcerative colitis is a serious but rare outcome. There are 16 reported cases. We report three additional cases and review previous cases in the literature.

Histological assessment of the distal 'doughnut' in patients undergoing stapled restorative proctocolectomy with high or low anal transection.

A non-randomized prospective study of 38 patients, 32 with ulcerative colitis and six with familial adenomatous polyposis (FAP), who underwent high or low anal transection during stapled restorative proctocolectomy was undertaken. The median (range) height of the staple line 6 months after operation was 5.2 (3.2-6.0) cm after high transection compared with 2.9 (1.8-3.6) cm after low transection. Nineteen of 20 patients after high anal transection had columnar epithelium in the distal 'doughnut' versus 16 of 18 after low transection. Active colitis was present in 12 of 19 'doughnuts' in patients with high anal transection and columnar mucosa and in seven of 16 after low transection. Nine patients (high transection two, low transection seven; P < 0.05) had striated muscle in the stapled distal 'doughnut'. Dysplasia was found in the resected colon in one patient with ulcerative colitis and adenocarcinoma in two colectomy specimens (ulcerative colitis, one; FAP, one). No dysplasia or carcinoma was seen in any of the 'doughnuts' from patients with ulcerative colitis. Four patients with FAP (high transection, two; low transection, two) had microadenoma in the distal 'doughnut'. Despite attempts to place a stapled pouch-anal anastomosis below the anal transition zone, it was not possible to remove columnar mucosa completely from the remaining anal canal in most patients (16 of 18). High anal transection and pouch-anal anastomosis should be the preferred option in restorative proctocolectomy, as a dentate-line anastomosis may not fully eliminate columnar epithelium and may involve resection of some of the external sphincter.

Prospective randomized trial to compare the stapled double lumen pouch and the sutured quadruple pouch for restorative proctocolectomy.

Thirty-three consecutive patients having restorative proctocolectomy since April 1986 were randomly allocated to reconstruction using a stapled J pouch (n = 18) or a sutured W pouch (n = 15). There were no deaths, but one patient required pouch excision for ischaemia (J). One patient developed a leak from the pouch necessitating loop ileostomy (J) and one patient had a low pouch vaginal fistula successfully treated by a seton (W). There were no other major complications. Median (range) operative time was 200 min (165-290) for J pouch and 255 min (220-330) for the W pouch (P less than 0.05). In 24 patients followed up for more than 4 months after restoring intestinal continuity, median frequency of defaecation over 24 h was 4 (3-6) for the J pouch and 4 (3-6) for the W pouch. There was no incontinence, urgency or soiling. These results indicate that the quicker J pouch provides identical functional results to the larger W pouch in this series of patients.

One- or two-stage procedure for restorative proctocolectomy: rationale for a surgical strategy in ulcerative colitis.

OBJECTIVE: To analyze the results of different strategies for restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) in ulcerative colitis. SUMMARY BACKGROUND DATA: No commonly accepted criteria exist for choosing between the one-stage or the two-stage procedure (with or without temporary diverting ileostomy) for IPAA. The authors analyzed the outcome of patients principally suitable for either of the two alternative surgical strategies. METHODS: A matched-pair control study was performed, comparing surgical details and the early and late outcome of the one-stage (study group, n = 57) versus the two-stage procedure (control group, n = 114), for IPAA. RESULTS: No differences were found between the study group and the control group regarding the matching criteria gender, median age at IPAA, systemic corticoid medication, or activity of colitis. Comparing the patients who underwent a one-stage procedure with those who underwent a two-stage procedure, the proportion of patients without complications was significantly higher (P =.0042) and the frequency of late complications was significantly lower (P =.0022) in patients who underwent the one-stage procedure. The percentage of patients with anastomotic strictures was significantly higher in the control group than in the study group (P =.0022). No significant difference was found between the two groups regarding early complications, pouch-related septic complications, pouchitis, median duration of surgery for IPAA, median blood loss, need for transfusion, or median hospital stay. CONCLUSIONS: In patients with ulcerative colitis in whom there is a choice between a one-stage procedure or a two-stage procedure with a defunctioning ileostomy, the one-stage procedure is clearly superior. This finding is of great clinical relevance both for the subjective interests of the patient and from an economic point of view.

Totally stapled abdominal restorative proctocolectomy.

A technique of totally stapled abdominal restorative proctocolectomy is reported in 20 consecutive patients using a 20 x 20 cm J pouch and a stapled ileoanal anastomosis. The stapled ileoanal anastomosis had to be abandoned in three patients because of attempted mucosectomy in one and megarectum in two. One patient receiving steroids had a covering ileostomy. The remaining 16 patients had a totally stapled procedure without a covering ileostomy. Three patients developed serious postoperative morbidity but they were the only patients receiving steroids at the time of the operation. Of the remaining 13 patients none developed serious complications, the median hospital stay was 14 days and the median operating time was 150 min. The operation may be a technical advance particularly in allowing pouch construction without ileostomy in fit patients who are not receiving steroids at the time of operation.

Constipation: another indication for restorative proctocolectomy.

We have extended our experience of restorative proctocolectomy and ileoanal anastomosis to include 13 patients with functional bowel disorders. Eight had recurrent constipation after colectomy for slow transit constipation and five had constipation and overflow incontinence associated with megarectum and megacolon. In all cases the only alternative was a permanent stoma. Despite a high complication rate, 11 patients (85 per cent) felt that the operation had been worthwhile with improvement of their symptoms and quality of life. The operation led to a mean frequency of defaecation of 4.8 times (range 2-8) during the day, and 1.2 times (range 0-4) during the night. There was no frank incontinence and, while only one patient experienced soiling during the day, six patients suffered from night-time soiling. Two patients have had the pouch converted to an ileostomy due to persistent complications and a poor functional result.

Closure of loop ileostomy after restorative proctocolectomy.

The outcome of loop ileostomy closure was evaluated in 40 patients who had previously undergone restorative proctocolectomy. A standard operative technique was used which incorporated a circumstomal incision, non-resectional reconstruction and primary skin closure. Thirty-six patients (90%) enjoyed an uncomplicated recovery. One patient (3%) developed a superficial wound infection. Enterocutaneous fistula was not encountered. Small bowel obstruction occurred in three patients (8%) two of whom required a further laparotomy, but subsequently made an uncomplicated recovery. No incisional hernias were identified at follow-up. We conclude that loop ileostomy closure can be achieved with a low morbidity which should not preclude the use of this stoma in restorative proctocolectomy.

Factors affecting anal continence after restorative proctocolectomy.

The aim of this multicentre study was to define the incidence of disordered continence after restorative proctocolectomy and ileoanal reservoir with respect to some factors which may influence the postoperative soiling rate. Two hundred and seven patients underwent the operation, 156 had their ileostomy closed and were all available for a functional assessment. Minor leakage was observed in 26.9% of cases, whereas 1.9% complained of troublesome faecal soiling. None had gross faecal incontinence. Patients over 45 years had significantly more soiling than those younger (45% vs 24%, p less than 0.05). Soiling was more prevalent in those with ulcerative colitis than with other diseases (35% vs 18% p less than 0.05). The soiling rate decreased after the first postoperative year from 34% to 21% (p less than 0.05). A bowel frequency higher than 5 evacuations/24 hours increased soiling from 20% to 48% (p less than 0.01). Pouchitis doubled the soiling rate from 26% to 50% (p less than 0.05) without there being any difference in sphincter function. Soiling was not significantly related to staged procedure, J-pouch, perineal complications or a long rectal cuff. Careful preoperative evaluation of the anal sphincter should be performed in older patients operated on for colitis as they are likely to leak during the first year following restorative proctocolectomy, especially in cases with diarrhoea or pouchitis.

Omission of temporary diversion in restorative proctocolectomy--is it safe?

PURPOSE: The aim of our study was to evaluate the safety and functional outcome of restorative proctocolectomy (RP) without diversion. METHODS: Fifty patients underwent RP without diversion for ulcerative colitis (82 percent), familial adenomatous polyposis (12 percent), and indeterminate colitis (6 percent). The perioperative course and functional outcome of these patients were compared with another group of 50 patients undergoing RP with diverting ileostomy during the same time period (1989-1991) and closely matched for age, gender, surgeon, diagnosis, extent and duration (median, 10 years) of colitis, prior colectomy (approximately 22 percent), steroid use (40 percent), type of pouch, distance of ileal pouch-anal anastomosis from the dentate line (median, 1.5 cm), and the duration of follow-up (median, 12 months). All patients had a stapled ileal pouch-anal anastomosis without mucosectomy and a smooth conduct of the operation. RESULTS: There was no operative mortality. Anastomotic leaks and pelvic abscess were more common in patients without ileostomy (7/50 or 14 percent vs. 2/50 or 4 percent); 8 of these 9 patients were taking > or = 20 mg of prednisone/day. Septic complications requiring relaparotomy (6 percent vs. 0 percent), prolonged ileus, and fever of unknown origin (10 percent vs. 4 percent) were also more common in patients without ileostomy. Despite similar functional results at 6 weeks and at 12 months after initial pouch function, patients without ileostomy had a poorer quality of life index (5 vs. 8; 10 being best) in the early period (0-6 weeks) of pouch function. CONCLUSION: In equally favorable cases, RP without diversion is not as safe as RP with diversion, especially in patients taking > or = 20 mg of prednisone/day.
