[Malignant transformation in ulcerative colitis and surgical implications].

Patients with ulcerative colitis (UC) are at higher risk for cancer. Risk factors are duration of disease, extent of colitis, associated primary sclerosing cholangitis and possibly early onset of UC in childhood. Epithelial dysplasias are considered as precursors of colorectal cancer within the concept of an inflammation-dysplasia-carcinoma sequence. Dysplasia originates multifocally and is difficult to identify by colonoscopy. Histomorphological diagnosis can also be problematical. Surveillance programs utilize colonoscopy with random biopsies to diagnose dysplasia in patients with risk factors. The efficiency of these programs can be markedly increased when certain rules are applied. The ultimate aim must be to perform a proctocolectomy in patients at higher risk before invasive cancer develops. With only a few exceptions, colorectal cancer in UC can be treated by restorative proctocolectomy. Partial resection of the colon should be avoided because of the high frequency of occult carcinomas and multifocal carcinogenesis. There are first results that indicate a higher risk for malignant deterioration in the terminal ileum. After an ileoanal pouch procedure patients with chronic pouchitis seem to have a higher risk for dysplasia. At the moment the risk for malignancy cannot be calculated because of the relatively short follow-up time after ileoanal pouch procedures. However, it is recommended that after restorative proctocolectomy patients be followed by endoscopy and random biopsies for the rest of their lives.

Total proctocolectomy and ileoanal pouch: the role of contrast studies for evaluating postoperative leaks.

BACKGROUND: To assess the role of contrast enemas for the evaluation of leaks in symptomatic and asymptomatic patients after the first stage of restorative proctocolectomy. METHODS: We reviewed the findings of 59 contrast enemas in 40 patients who underwent total proctocolectomy with creation of an ileoanal pouch and a proximal diverting ileostomy. Thirty-seven patients initially underwent routine contrast studies of the ileoanal pouch, and three underwent contrast studies because of suspected fistulas or obstruction. Medical records were also reviewed to determine the clinical presentation and course of these patients. RESULTS: Of 37 patients who underwent routine postoperative contrast enemas, 33 (89%) had normal studies, three (8%) had clinically silent leaks (including two blind-ending tracks from the ileoanal anastomosis and one from the pouch), and one (3%) had pouchitis. In all three patients with unsuspected leaks, ileostomy closure was delayed. In two other patients with abdominal pain and fever, contrast enemas revealed leaks from the ileoanal pouch and distal ileum, respectively. The remaining patient had a contrast enema because of abdominal pain and distention; this patient had a distal ileal obstruction due to adhesions. CONCLUSIONS: Routine postoperative contrast studies revealed clinically silent leaks from the ileal J pouch or ileoanal anastomosis in three of 37 patients (8%) after the first stage of restorative proctocolectomy. Our findings suggest that routine contrast enema can detect clinically silent leaks after this surgery.

[Long-term quality of life after continence-preserving proctocolectomy for ulcerative colitis and familial adenomatous polyposis].

After ileal pouch-anal anastomosis in patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP), quality of life is a relevant factor for the assessment of the operation's success, in addition to postoperative morbidity and functional outcome. Between 1982 and 1995 restorative proctocolectomy was performed in 453 patients (UC: n = 332; FAP: n = 121) at the Department of Surgery, University of Heidelberg. We studied postoperative quality of life through a long-term follow-up study (median follow-up time 43.2 months). This study 1 year or more following ileostomy closure of persons who had undergone J-pouch anastomosis (n = 243 total; UC n = 185, FAP n = 58) revealed that at the time of follow-up, the underlying disease (UC versus FAP) and successfully treated complications are without influence on the quality of life. The patient's age (P < 0.01) and the presence of unsuccessfully treated complications (P < 0.0001) showed a significant influence on the quality of life. There was a distinct relation between the functional index and the quality of life index (coefficient of correlation r = -0.714). However, quality of life, comparable to that of healthy controls, can be achieved with UC and FAP patients by restorative proctocolectomy only if postoperative complications can be avoided or are successfully treated.

Combined molecular and clinical approach for decision making for surgery in HNPCC patients: a report on three cases in two families.

Hereditary nonpolyposis colorectal cancer (HNPCC) is associated with highly penetrant germline mutations in mismatch repair genes. Due to a high lifetime risk in gene carriers for synchronous and for metachronous colorectal cancer and endometrial cancer in women, prophylactic and extended surgery are considered as options for gene carriers. A 54-year-old patient with a history of metachronous rectal cancer and a family history fulfilling the Amsterdam criteria presented with carcinoma of the cecum and highly dysplastic adenomas of the splenic flexure and descending colon. As a result of these findings, medical history and molecular diagnosis, the decision was made to perform colectomy and prophylactic hysterectomy with oophorectomy; histological examination of the specimen showed three synchronous colon carcinomas. The 31-year-old son carrying the pathogenic mutation refused to be included in the HNPCC surveillance program. One year later he presented with symptoms of bowel obstruction, and a carcinoma of the descending colon was diagnosed. Intraoperatively, in addition to the colon cancer, a small bowel cancer and peritoneal carcinomatosis were found. In another family fulfilling the Amsterdam criteria without known germline mutation a woman presented with synchronous cancer of the ascending colon and the lower rectum at the age of 49 years. Proctocolectomy and prophylactic hysterectomy were performed, which revealed an additional colon cancer and endometrial cancer. We discuss approaches for individual decision making for surgery in HNPCC patients. Is a subtotal colectomy indicated in the case of first colon cancer in HNPCC patients, or if the first tumor occurs in the lower rectum, should a proctocolectomy or a restorative proctocolectomy be considered? The aim of prospective clinical studies should be to assess acceptability, survival rates, mortality, and the quality of life in HNPCC patients who have undergone surveillance and standard oncological resections versus extended or prophylactic surgery.

Pouch-anal anastomosis without diverting ileostomy.

Ileal diversion is an important adjunct to restorative proctocolectomy but may produce increased morbidity and requires a second-stage closure. This study reports results utilizing a one-stage procedure designed to retain the benefits of proximal decompression without the liabilities of additional surgical procedures. Eight patients, three men (with ulcerative colitis) and five women (one with familial polyposis coli and four with ulcerative colitis), were selected for the single-stage restorative proctocolectomy with intraluminal decompression in lieu of diverting loop ileostomy. The abdominal proctocolectomy was performed to the level of the anorectal junction. In five patients, the rectum was closed using the TA 55 (U.S. Surgical Corporation, Norwalk, CT), 4.8-mm stapler. AJ-pouch was constructed with multiple firings of the GIA90 (U.S. Surgical Corporation) stapler. These patients had continuity restored utilizing a transanal, circular stapler. Three patients had an S-pouch constructed by suture technique. Fecal diversion was accomplished with a 25-mm intraluminal bypass tube (Coloshield; Deknetel, Fall River, MA) in all cases. There was no mortality. There were no anastomotic complications or morbidity related to the bypass tube. The tube dislodged and passed between days 18 and 26 (mean, 22.1 days). All patients had three to six bowel movements per 24 hours, and all are continent day and night. This experience suggests that, in selected patients, the intraluminal bypass tube may be an excellent alternative to diverting ileostomy.

Choice of prophylactic surgery for the large bowel component of familial adenomatous polyposis.

The surgical options for treating the large bowel component of familial adenomatous polyposis are total proctocolectomy, colectomy with ileorectal anastomosis, and restorative proctocolectomy, with or without mucosectomy. Although the first of these eradicates all mucosa at risk, it carries several disadvantages, not least of which is a permanent ileostomy. There is little to choose functionally between the other two operations. The choice should be based on the perceived risk of cancer developing in any residual rectum; the factors influencing this risk are discussed.

[Controversy--surgical vs. medical management of inflammatory bowel disease].

The controversy in the treatment of inflammatory bowel disease is how to decide surgical vs. medical management in each case. Of 309 patients with ulcerative colitis in our department, 63 (20%) patients had received surgical treatment. The mean age was 33.5 +/- 13.7 years old and the mean duration from onset to operation was 6.72 +/- 5.51 years. The indications for surgical treatment were 47 (75%) resistant cases against medical treatment, 9 (14%) severe cases and 7 (11%) cancer or dysplasia cases. In surgical cases compared with medical ones, the ratio of total duration (months)/number of admission showed below 10, and the total amount of used steroid was over 300 mg per month. These ratios were considered to be the useful markers for surgical indication. Operative procedures were 15 total proctocolectomy+ileostomy, 29 total colectomy+ileorectal anastomosis, 13 total proctocolectomy+ileoanal anastomosis and 6 others. Restorative proctocolectomy using double stapling method with two stage operation was chosen in 8 patients because of easier and safer operative procedure and a few complications. We conclude that early surgical treatment for the patients resistant against medical management is considered to improve the patients' quality of life.

Abdominopreanal proctocolectomy and ileal U-pouch in ulcerative colitis or familial adenomatous polyposis.

In some cases of ulcerative colitis and familial adenomatous polyposis, cancerous changes frequently occur on the distal rectum, in which case a restorative proctocolectomy is not recommended because of the limitations of a radical resection. Even if rectal cancer is not confirmed preoperatively, a strong possibility of cancer in the rectum could afford some support for a radical pelvic dissection during the anus-sparing procedure. The author designed a new operative procedure for resolving this problem. It is an abdominopreanal extrasphincteric proctocolectomy with preileal-pouch positioning of the distal ileal segment including the ileocecal sphincter (ileal U-pouch) for the treatment of ulcerative colitis and familial adenomatous polyposis coli (restorative radical proctocolectomy). The author performed this restorative radical proctocolectomy on seven patients over the past 5 years at the Department of Surgery, Pusan National University Hospital, of which four cases were ulcerative colitis and three were familial adenomatous polyposis. The results obtained were as follows: (a) The most common sequela was nocturnal seepage, which lasted for 6 months in 4 patients after the final operation. (b) The mean frequency of defecation was six times per day at 6 months after the final operation. (c) The average amount of stool was about 460g per day at 6 months after the final operation. Therefore, the ileal U-pouch is considered to be effective in reducing the daily amount of stool. A preanal extrasphincteric approach could be especially useful in the case of a difficult dissection of the anterectal space while also providing an effective dependent drainage of the ileoanal anastomotic space.

Restorative compared with conventional proctocolectomy for the treatment of ulcerative colitis.

OBJECTIVE: To evaluate the clinical differences between conventional and restorative proctocolectomy in the treatment of ulcerative colitis. DESIGN: Retrospective analysis. SETTING: University hospital, Finland. SUBJECTS: 240 consecutive patients with ulcerative colitis who underwent elective proctocolectomy between 1976 and 1990. INTERVENTIONS: Proctocolectomy and conventional ileostomy (n = 119) or restorative proctocolectomy (n = 121). MAIN OUTCOME MEASURES: Early and late surgical morbidity and recovery time. RESULTS: There were no postoperative deaths after restorative proctocolectomy and one patient (1%) died after conventional proctocolectomy. Two other patients (2%) with ileostomies died of late complications. Delayed perineal would healing after conventional ileostomy (n = 45, 38%) and either early (n = 31, 26%) or late (n = 19, 16%) defects of the ileoanal anastomosis after restorative proctocolectomy caused most problems. Reoperations (early or late) were needed in 45 (38%) and 44 (36%) patients after Brooke ileostomy and restorative proctocolectomy, respectively. Major complications, however, were more common and the duration of sick leave was a month longer in the pouch group. CONCLUSION: Ulcerative colitis can safely be managed with either conventional or restorative proctocolectomy. In most cases the patient's preference should dictate the choice of procedure.

Improvement of anal sensation with preservation of the anal transition zone after ileoanal anastomosis for ulcerative colitis.

One of the most important considerations in restorative proctocolectomy for ulcerative colitis is postoperative continence. Preservation of the anal transition zone has been associated with improved results after this procedure in the pediatric age group. This study was carried out to determine the effect of preservation of the amal transition zone in adult patients undergoing restorative proctocolectomy, comparing a group of patients with the anal transition zone preserved with a group of patients with the anal transition zone removed. Physiologic testing demonstrated improved sensation in those patients with a preserved anal transition zone. Functional results were not significantly improved, although there was a trend toward improved continence and discrimination in those with the anal transition zone preserved. Although the results are early and are not conclusive from the clinical standpoint, they are certainly encouraging and may justify continued use of this technique.

S-pouches vs. J-pouches. A comparison of functional outcomes.

Subjects undergoing proctocolectomy with ileoanal anastomosis of either a J-shaped or an S-shaped ileal reservoir were studied with respect to functional status. Both subjective and objective measures were used. The S-pouch subjects appeared to have better early functional results, but no differences were found between groups evaluated at least one year from ileostomy closure. While virtually all subjects preferred restorative proctocolectomy to their previous loop ileostomy, there was a relatively high frequency of bowel-related symptoms, worries about bowel activity, and associated behavioral changes. The actual significance of these symptoms is difficult to determine at present. Further assessment of the quality of life in individuals with restorative proctocolectomy in comparison with subjects undergoing alternative surgical treatments is recommended.

Proctocolectomy and ileoanal anastomosis with an S pouch: functional results.

Patients with total colonic ulcerative colitis or familial polyposis traditionally require a proctocolectomy. In an effort to preserve the normal pathway for defecation and avoid the nuisance of an abdominal stoma, a continence-preserving procedure involving a pelvic reservoir has been performed at the University of Minnesota Hospitals on 120 patients. The majority were operated on for colonic ulcerative colitis. There were no deaths. The mean hospital stay after restorative proctocolectomy was 10 days and after ileostomy takedown the mean stay was 7 days. Functional results were assessed in 52 patients. Daytime bowel movements averaged 6.4 and night-time movements 1.4. Major daytime incontinence occurred in 6% of the patients, 21% had moderate soiling at night and 70% wore a perineal pad in the evening. Ninety-two percent of the patients expressed satisfaction with the procedure. The most serious complication was pelvic sepsis. It occurred in nine patients, six of whom required subsequent surgery. The Parks S pouch provides a means of maintaining anal continence. This series and others have shown that young, healthy, well-motivated persons will benefit most from a restorative proctocolectomy.

Familial juvenile polyposis: patterns of recurrence and implications for surgical management.

BACKGROUND: Familial juvenile polyposis predisposes to the development of carcinoma of the colon. Optimum surgical management and recommended surveillance of affected individuals are still being defined. STUDY DESIGN: A retrospective review of experience with a kindred identified in 1988 was carried out. RESULTS: Of 34 living members, 15 have been investigated, and histologically typical juvenile polyps were found in 11. In each instance, polyps were most numerous in the right colon, with few polyps in the descending colon and none in the rectum. Eight patients have had subtotal colectomies with ileorectal anastomoses; the remaining patients were managed by polypectomy (with one recurrence after ten years). In addition to juvenile polyps, polyps with adenomatous or villous elements were identified in three patients. One of these patients had invasive adenocarcinoma in a large mixed polyp of the cecum. Two patients with polyps had coexisting carcinoma of the stomach. All patients have been followed up with periodic upper and lower gastrointestinal endoscopy. Polyps have recurred in the rectal remnants of three patients at a mean of 36 months after subtotal colectomy. Two patients have undergone conversion to total proctocolectomy with ileoanal anastomosis and J pouch; one patient was found to have juvenile polyps in the pouch 40 months after surgery. CONCLUSIONS: Despite the preponderance of right-sided polyps at initial diagnosis, the rapid recurrence of polyps after subtotal colectomy argues in favor of performing proctocolectomy with preservation of anal sphincter function (restorative proctocolectomy) at the time of initial surgery. Patients with a small number of polyps may choose instead to undergo periodic colonoscopy with colonoscopic polypectomy. An algorithm for surveillance and follow-up is proposed.

[Determinants of pouch function after continence-preserving proctocolectomy].

A prospective study was undertaken in 17 patients undergoing restorative proctocolectomy for ulcerative colitis (13 patients) or familial adenomatous polyposis (4 patients) to determine relationship between pre- and postoperative anal sphincter function, pouch characteristics and functional results. Postoperatively all manometric parameters were significantly reduced and remained so permanently. Only squeeze pressure rose to normal values again. The most important factor for a favourable functional outcome was pouch volume. A capacious reservoir was associated with a low stool frequency, low risk of incontinence and general success of the operation, as assessed subjectively. Perianal soreness with considerable skin problems occurred frequently when resting and squeeze pressures were markedly reduced postoperatively.

[Proctocolectomy with ileal W pouch anal anastomosis for ulcerative colitis].

Restorative proctocolectomy with ileal pouch anal anastomosis, which is a relatively new procedure, has become a standard procedure for ulcerative colitis (UC) requiring surgical management. The main impact of this procedure is to cure patients of disease and to avoid permanent ileostomy, preserving better defecatory function and acceptable QOL. Some key aspects of our surgical procedure are as follows: 1) two or three separate staged operation, 2) W-shaped reservoir, 3) distal rectal mucosectomy and handsewn ileo-anal anastomosis, 4) short muscular cuff, and 5) temporary diverting ileostomy. Staged operation and diverting ileostomy are helpful to decrease risk of pelvic infection. Total removal of the rectal mucosa is necessary to cure the disease, and shorter muscular cuff decreases operating time and bleeding and thus the risk of pelvic sepsis. The W-shaped reservoir described by Nicholls brings both spontaneous defecation and improved function. We have adopted ileal W-pouch among several types of reservoir to 58 patients with UC since 1984, and found that a large and wide reservoir might allow better defecatory function. There were no cases of serious complications and no needs to remove the reservoir. Mean daily stool frequency was gradually decreased with time, and 4.9 stools per 24 hours at present day, and clinical score of neorectal function also gradually improved according to reduction of stool frequency. Seventy three percent of patients felt their defecatory function satisfactory and 89% of the patients recovered acceptable QOL no less than that obtained during the medically treated period.

Traumatic perforation of ileal pouch. Report of a case.

A 28-year-old woman with a previous history of restorative proctocolectomy for complicated ulcerative colitis had acute onset of severe abdominal pain that was diagnosed at another hospital as a perforated peptic ulcer. Careful history-taking revealed that she had blunt trauma to the abdomen one day before admission. Laparotomy detected a perforation hole at the afferent loop of the ileal pouch. Debridement and primary closure of the perforation, with temporary decompression of the pouch, resulted in a good outcome. With the increasing popularity of selecting restorative proctocolectomy for the treatment of polyposis coli and ulcerative colitis, more and more pouches will be constructed. Possible perforation of the ileal pouch should be considered when such patients present with a perforated hollow viscus. With appropriate management, the pouch can be saved. Review of the literature revealed no similar reports.

The effects of atropine or benzilonium on pelvic pouch and anal sphincter functions.

Anticholinergic drugs are used on an empirical basis for treatment of functional disturbances after restorative proctocolectomy, but their mode of action on ileal pouch performance is mainly unknown. We studied the acute effects of atropine or benzilonium on pouch characteristics and anal sphincter function in 20 patients with a pelvic pouch. Pouch volume was increased by 27% by atropine at distension with 20 cm H2O (p less than 0.01). Benzilonium tended to have a similar effect, but the changes did not reach statistical significance (p = 0.06). Pouch contractility, as reflected by volume fluctuations and pressure changes during distension, was almost abolished by both drugs. Sensory thresholds for sense of filling and, particularly, urge were raised. Resting anal pressure was slightly lowered, whereas no significant effect was found on maximal squeeze pressure. In conclusion, anticholinergics appear to have specific properties of action on small-intestinal reservoirs, constituting possible explanations for the empirically observed beneficial effects of anticholinergic treatment of functional disturbances after restorative proctocolectomy.

Manovolumetric characteristics and functional results in three different pelvic pouch designs.

Different pouch designs and techniques for the perineal approach have been on trial in an attempt to improve results after restorative proctocolectomy. The 1-year results of two currently advocated procedures, the J-pouch and the S-pouch, were compared with the results obtained in patients with a pelvic pouch fashioned according to the folding technique used for the Kock continent ileostomy, all pouches having been constructed from equal 30 cm lengths of ileum. The maximal volume of the S- and Kock pouches at one year was 420 ml (250-570) (median and (range] and 410 ml (244-490) respectively, while it was significantly less, 305 ml (200-445) in the J-pouch (p less than 0.05). The compliance of the J-pouches was also significantly lower at all distension pressures. The median day-time defaecation frequency was four and was equal in the three groups. Although there was a tendency towards a more favourable overall functional result with less soiling, and less need for night evacuations among patients with a Kock-folded pouch compared to the other pouch types these differences failed to reach statistical significance. The favourable properties of the Kock pouch, well-known also from the conteinent ileostomy and urostomy, suggest that its design should be considered an interesting alternative even for restorative proctocolectomy. These encouraging results have yet to be confirmed in a comparative randomized trial.
