Causes and outcomes of pouch excision after restorative proctocolectomy.

BACKGROUND: Pouch failure occurs in up to 10 per cent of patients after ileal pouch-anal anastomosis (IPAA). The aims of this study were to determine the reasons for pouch excision and to evaluate the outcome of the perineal wound after pouch excision. METHODS: Between 1984 and 2002, 91 patients with severe ileal pouch dysfunction were treated. This was a retrospective analysis of data collected prospectively from 24 patients who underwent pouch excision. RESULTS: Patients were grouped according to the final histological diagnosis. Fourteen patients with Crohn's disease developed extensive fistulous disease and/or recurrent abscesses, of whom six had a persistent perineal sinus after pouch excision. Five patients had familial adenomatous polyposis, in three of whom desmoid tumours were the cause of failure. Three patients had chronic ulcerative colitis and developed recurrent pelvic sepsis. Finally, two patients with multiple colorectal adenocarcinoma developed recurrent cancer (one) or sepsis (one). CONCLUSION: Sepsis was the principal reason for pouch excision and was usually associated with recrudescent Crohn's disease in the pouch. Perineal wound healing was problematic after pouch excision for Crohn's disease.

Randomized trial to determine the optimum level of pouch-anal anastomosis in stapled restorative proctocolectomy.

PURPOSE: This study was undertaken to identify the optimum level of stapled ileal pouch-anal anastomosis. METHOD: A prospective, randomized trial was completed to compare double-stapled ileoanal anastomosis placed at the top of anal columns (high, n = 26) with anastomosis at the dentate line (low, n = 21). RESULTS: There was no significant difference in the overall complication rate between operations (high, n = 7, vs. low, n = 8; P < 0.21). Pouch-anal functional score (scale 0-12; 0 = excellent, 12 = poor) was significantly better in the high anastomosis group (median (range): 2 (1-9) vs. 5.5 (1-12); P < 0.05). Incontinence occurred in only two patients randomized to high anastomosis compared with six in the low anastomosis group. Nocturnal soiling was reported in three patients after high anastomosis and in six patients after dentate line anastomosis. Both operations caused a significant but comparable reduction of maximum and resting pressure (31 percent after high anastomosis (P < 0.05); 23 percent after low anastomosis (P < 0.05)). However, a significant fall in functional length of the anal canal was only seen after a low pouch-anal anastomosis (P < 0.05). CONCLUSION: Stapled pouch-anal anastomosis at the top of anal columns gives better functional results compared with a stapled anastomosis at the dentate line.

Follow-up results of hematology data before and after restorative proctocolectomy. Clinical outcome.

PURPOSE: This study was designed to investigate the development of anemia during functional ileoanal pouch. METHODS: Eighty-three patients received an ileoanal pouch between 1980 and 1987. The hematology data deviations among the preoperative period, defunctionalized stage, and after ileal pouch in function were monitored. Aspects studied included serum hemoglobin, iron, folates, vitamin B12, white blood cell, erythrocyte sedimentation rate, pt-B12, and fat absorption. Specimens were collected before colectomy, during ileostomy prior to pouch operation, before loop ileostomy closure, and at 6, 12, 18, 24, and 36 months after loop ileostomy closure. RESULTS: Two patients developed iron deficiency anemia after 2.5 and 5 years of pouch function: one patient, a vegetarian, had low hemoglobin, iron, and vitamin B12 postoperatively, the other patient developed low iron and hemoglobin 5 years after the operation. Significant elevations of serum hemoglobin, iron, and folates were seen preoperatively vs. postoperatively from 123.46 +/- 2.845 g/l, 10.282 +/- 0.992 mumol/l, and 9.983 +/- 1.308 mmol/l to 138.842 +/- 1.563 g/l (P < 0.0001), 17.544 +/- 1.529 mumol/l (P < 0.0003), and 16.784 +/- 1.757 mmol/l (P < 0.01) (mean +/- SE) of the defunctionalized loop ileostomy. Serum B12 decreased insignificantly. After loop ileostomy closure, at 6 and 36 months of functional ileal pouch-anal anastomosis, the elevations were still significant; serum hemoglobin was P < 0.0001 and P < 0.01, and serum iron was P < 0.001 and P < 0.01, respectively. Vitamin B12 levels decreased insignificantly at six months in controls and significantly (P < 0.01) at 36 months. There was a significant increase of serum folates (P < 0.01 and P < 0.001). Patients with low iron were 50 percent at precolectomy, 23 percent with ileostomy, 16 percent with loop ileostomy, 15 percent at six-month follow-up, and 11 percent at 12-month follow-up. Although only 3 percent and 11 percent of the patients with ileal pouch-anal anastomosis had low serum vitamin B12 values at the 12-month and 36-month follow-up, 31 percent and 36 percent had decreased Schilling tests. Thirty-three percent and 41 percent had decreased 14C-triolein breath tests. In five patients vitamin B12 deficiency began during the first six months of pouch function: in two patients after one year and in one patient after two years. Eight of 83 patients have had substitution therapy with vitamin B12. The therapy was discontinued in three patients after two to four years; these patients developed no further symptoms and had normal Schilling tests in the succeeding 30 months to 46 months. Five patients continue with substitution after 40 months to 68 months. During the functional period, serum erythrocyte sedimentation rate and white blood cells were elevated in some controls on different occasions. Folates were normal throughout the functional period. CONCLUSION: For predicting hematologic data outcome in patients with functional ileal reservoir, the results justify the necessity for control during both manipulative and functional periods until evaluations are reliable and satisfying.

Substance P- and vasoactive intestinal polypeptide-immunoreactive innervation in normal and inflamed pouches after restorative proctocolectomy for ulcerative colitis.

Recent studies suggest that the intestinal polypeptides substance P (SP) and vasoactive intestinal polypeptide (VIP) play a role in the bowel inflammatory processes. The aim of this study was to evaluate the distribution of SP and VIP immunoreactivities in the ileal pouch of the patients with ulcerative colitis (UC). Thirty-six patients underwent clinical evaluation, endoscopy, and histological examinations. Samples were taken from normal ileum (N = 9), ileum of UC patients (N = 9), normal ileal pouch (N = 9) and pouchitis (N = 9). SP- and VIP-containing nerve fibers were visualized in sections processed for immunofluorescence microscopy. The number and intensity of SP and VIP immunoreactivities were subjected to quantitative scoring. On samples from all groups lamina propria contained fibers showing bright immunofluorescence for SP and VIP. The number and intensity of SP immunoreactive nerve fibers were markedly increased in pouchitis as compared to normal pouch (P < 0.005), to ileum of UC patients (P < 0.001), and to normal ileum (P < 0.05). The number and intensity of VIP-immunoreactive nerve fibers in the lamina propria were markedly increased in pouchitis patients and in those having a normal pouch as compared to pooled values of ileum of UC patients and normal ileum (P < 0.05). The results suggest that SP, which may play a role in mediating inflammatory processes, is increased in pouchitis and that VIP, which may contribute to the regulation of intestinal motility, is increased in the pouch.

Functional outcome, quality of life, body image, and cosmesis in patients after laparoscopic-assisted and conventional restorative proctocolectomy: a comparative study.

PURPOSE: The aim of this study was to assess the functional outcome and the quality of life of laparoscopic-assisted ileal pouch-anal anastomosis compared with conventional ileal pouch-anal anastomosis. Further, body image and cosmesis were evaluated in both groups. METHODS: Sixteen patients who underwent a laparoscopic-assisted ileal pouch-anal anastomosis between March 1996 and September 1999 were matched with 19 patients who had a conventional ileal pouch-anal anastomosis. Patients were matched for the time period after surgery, distribution of familial adenomatous polyposis/ulcerative colitis, and one/two-stage procedure. Thirty-two patients agreed to fill out a set of questionnaires that assessed functional outcome, quality of life, body image, and cosmesis. Quality of life was measured with the Short Form 36 Health Survey questionnaire and the Gastrointestinal Quality of Life Index. The Body Image Questionnaire was used to measure patients' perceptions of and satisfaction with their own body and their attitude toward their bodily appearance (body image) and the degree of satisfaction of patients with respect to the physical appearance of the scar (cosmesis). RESULTS: Patients in the conventional group were older than patients in the laparoscopic-assisted group (mean 39.2 +/- 8.4 vs. 30.6 +/- 7.1 years; P < 0.01). No differences were found in functional outcome and quality of life. Satisfaction with the cosmetic result of the scar was significantly higher in the laparoscopic-assisted group compared with the conventional group. Body image score was higher in the laparoscopic-assisted group when compared with the conventional group, although not significant. CONCLUSIONS: The functional outcome and quality of life of laparoscopic-assisted ileal pouch-anal anastomosis is not different from conventional ileal pouch-anal anastomosis. In the long-term, better cosmesis is the most important advantage after laparoscopic surgery.

Pouch excision for recurrent serrated adenomas following restorative proctocolectomy for juvenile polyposis: report of a case.

PURPOSE: The study contained herein was undertaken to report the case of a patient with juvenile polyposis in whom multiple and rapid recurrence of mixed polyps, with progressive predominance of the adenomatous component, developed in a diverted ileoanal pouch. METHODS: The case of this patient with juvenile polyposis was reviewed. Despite regular surveillance and polypectomies, extensive and multiple recurrences of serrated polyps developed. RESULTS: Because the pouch was never cleared of polyps, a compromise to remove the pouch was decided on. Such a case has not been reported previously. CONCLUSION: Mixed juvenile polyposis may affect any level of the gastrointestinal tract. The ileal pouch and any rectal remnant may incidentally need surgical excision.

Budd-Chiari syndrome complicating restorative proctocolectomy for ulcerative colitis: report of a case.

PURPOSE: This is a case of hepatic vein thrombosis presenting in a delayed fashion after proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis. Search for a causative thrombotic condition resulted in the diagnosis of polycythemia vera, a myeloproliferative disorder associated with hypercoagulability. The polycythemia was masked by an iron deficiency associated with the ulcerative colitis. METHODS: The history, physical, diagnostic modalities, and treatment for this patient are described, and the literature of Budd-Chiari syndrome associated with ulcerative colitis is reviewed. RESULTS: Six cases of Budd-Chiari syndrome in the setting of ulcerative colitis are reported in the literature from 1945 to 1997. CONCLUSIONS: Hepatic vein thrombosis is a rare complication of ulcerative colitis. The diagnosis of Budd-Chiari syndrome demands a thorough search for a hematologic condition predisposing to thrombosis. Our patient had a myeloproliferative disorder, polycythemia vera, that is associated with a hypercoagulable state. The disorder was masked by an iron deficiency associated with the ulcerative colitis. Recognition of the entity will permit successful treatment.

[Typical complications and their control after restorative proctocolectomy].

The overall rate of complications after ileal pouch-anal anastomosis is 60%. This rate, however, includes complications such as bowel-obstruction and hernias. Pouch-related complications occur after ileal pouch-anal anastomosis with a frequency of 15-25%. In an analysis of the recent literature the main risk factors are: tension of the ileal pouch-anal anastomosis, anastomotic leakage, lack of protective ileostomy, preoperatively undiagnosed Crohn's disease and the experience of the surgeon. We classified pouch related-complications into (1) surgical complications (leakage, bleeding, pelvic sepsis, fistulas); (2) technical problems (long S-pouch spout, rectal cuff stenosis, etc.); (3) functional problems (anal sphincter insufficiency, night incontinence, hypermotility, evacuation disorders); (4) pouchitis; (5) pouch neoplasias. Pathogenesis, diagnostic features, and medical and surgical therapy are discussed in detail. In our own series of 11 pouch-redo operations we had 6 pouch fistulas (3 related to Crohn's disease, 3 postoperative fistulas), 3 wrongly constructed pouches, 1 chronic pouchitis and 1 long S-pouch spout. In 3 cases the pouch had to be excised completely. Two patients remained with a permanent ileostomy. In 6 patients the pouch could be preserved on long term. Due to the technical complexity, the need to understand pathophysiology and the need for a differentiated diagnostic procedure, this operation should be performed only in specialised centers.

The role of scintigraphic defecography in the assessment of bowel function after restorative proctocolectomy for ulcerative colitis.

BACKGROUND: The aim of the study was to evaluate the efficiency of defecation in patients with ileal pouch for ulcerative colitis by using the mean of scintigraphic defecography. METHODS: Sixteen patients were classified into two groups according to the presence of good (group A) or poor (group B) pouch function. Emptying efficiency was calculated by scintigraphic defecography and measured as percentage of evacuation. This involves the use of up to 200 ml of an artificial stool made up of methyl cellulose paste labeled with 180 MBq of technetium-99 m (Tc-99 m) methylene diphosphonate. Potential causes of increased frequency in the absence of additional associated symptoms of dysfunction were excluded in all patients. Maximum tolerated volume (MTV) and balloon expulsion tests were also performed on all patients. RESULTS: No patient in both groups showed evidence of organic pouch dysfunction. Percentage of emptying was higher in patients of group A (n=6) than in group B (n=10) (81+/-9 vs 71+/-9%, respectively, P<0.05; correlation, -0.51, P<0.04). Mean MTV was similar in the two groups (group A: 361+/-118 ml and group B: 338+/-77 ml, P=0.7). Results of the balloon expulsion test were normal in all patients except for one individual in group B. CONCLUSION: In patients with ileal pouch for ulcerative colitis, increased frequency of defecation without any evidence of pouch dysfunction may be correlated with an alteration of emptying efficiency. Scintigraphic defecography is appropriate to use for investigation of this condition with no disadvantages for the patients.

Laparascope-assisted versus conventional restorative proctocolectomy with rectal mucosectomy.

To assess the advantages of a laparoscope-assisted proctocolectomy with ileal J-pouch anal anastomosis compared with conventional procedures, we retrospectively analyzed the results of the two procedures as follows: Eleven patients including five patients with familial adenomatous polyposis (FAP) and six with ulcerative colitis (UC) underwent a laparoscope-assisted proctocolectomy and hand-sewn ileal J-pouch anal anastomosis at our department from June 1997 to November 1999. This laparoscope-assisted colectomy (LAC) group was then compared with a group of 13 patients who had undergone conventional ileal pouch anal anastomosis using a standard laparotomy from 1986 to 1997. The median operative time of the LAC group was 8h 23min, which was 81 min longer than that of the standard colectomy (SC) group. The number of days during which eating was prohibited were similar in the two groups but the median postoperative hospital stay was significantly shorter in the LAC group (24.1 days). In the LAC group, the small incisions showed better cosmetic results and there was also a remarkable reduction in the degree of postoperative pain. In conclusion, a laparoscope-assisted proctocolectomy with ileal J-pouch anal anastomosis can be employed widely in patients with FAP and also in selected patients with UC.

Full-thickness pouch prolapse after restorative proctocolectomy: a potential future problem treated by the new technique of external pelvic neorectal suspension (the Express procedure).

Full thickness pouch prolapse following restroative proctocolectomy is an uncommon complication but likely to become more frequent as this population of patients grows older. Conventional procedures to correct the prolapse may be impossible or significantly risk permanent ileostomy formation. The Express technique which is relatively minimally invasive, is a perineal procedure which elevates and suspends the antero-lateral walls of the prolapsing pouch to the external surface of the pelvis, utilizing strips of long lasting collagen.

The effect of Crohn's disease on outcomes after restorative proctocolectomy.

PURPOSE: This study was designed to compare postoperative adverse events and functional outcomes after ileal pouch-anal anastomosis between patients with Crohn's disease and those with non-Crohn's disease diagnoses. METHODS: A literature search was performed to identify studies published between 1980 and 2005 comparing outcomes of patients undergoing ileal pouch-anal anastomosis for Crohn's disease, ulcerative colitis, and indeterminate colitis. Random-effect, meta-analytical techniques were used and sensitivity analysis was performed. RESULTS: Ten studies comprising 3,103 patients (Crohn's disease=225; ulcerative colitis=2,711; indeterminate colitis=167) were included. Patients with Crohn's disease developed more anastomotic strictures than non-Crohn's disease diagnoses (odds ratio, 2.12; P=0.05) and experienced pouch failure more frequently than patients with ulcerative colitis (Crohn's disease vs. ulcerative colitis: 32 vs. 4.8 percent, P<0.001; Crohn's disease vs. indeterminate colitis: 38 vs. 5 percent, P<0.001). Urgency was more common in Crohn's disease compared with non-Crohn's disease: 19 vs. 11 percent (P=0.02). Incontinence occurred more frequently in Crohn's disease compared with non-Crohn's disease patients: 19 vs. 10 percent (odds ratio, 2.4; P=0.01). Twenty-four-hour stool frequency did not differ significantly between Crohn's disease, ulcerative colitis, or indeterminate colitis. Patients with isolated colonic Crohn's disease were not significantly at increased risk of postoperative complications or pouch failure (P=0.06). CONCLUSIONS: Patients with Crohn's disease undergoing ileal pouch-anal anastomosis should be appropriately counseled toward poorer functional outcomes and higher failure compared with non-Crohn's disease patients. It maybe possible to preoperatively select patients with isolated colonic Crohn's disease who may benefit from ileal pouch-anal anastomosis with acceptable adverse outcomes.
