[Experiences with the Kock continent ileostomy].

First experiences with Kock-pouches (KP) in 34 patients operated on between 1987 and 1992 with stapler-stabilization of the nipple-valve are reported. 18 patients (52.9%) suffered from ulcerative colitis (CU), 7 patients (20.6%) from familiar adenomatous polyposis (FAP) and 9 patients (26.5%) from Crohn's colitis (CC). Each patient was inappropriate for ileo-anal pouch-procedure (IAP) and desired fecal control. Special indications for KP were identic with medical contraindications for IAP in 52.9%, refusal of IAP in 17.6% and loss of sphincter in 29.4%. In 25 patients with CU and FAP the rate of specific early complications was 24%. In 5 of 6 cases operative correction was successful. The rate of success was 96%, which could be maintained over time with a rate of 8.3% of late complications, that had to be corrected. In 9 patients with CC the rate of success was 77.8% due to two pouch resections in the early postoperative course. It decreased to 66.6% in the further course due to another resection later on. In CC, 3 out of 7 patients had repeated reoperations due to inflammatory complications of the disease not impairing pouch-function. A severe pouchitis was only observed in 2/18 patients with CU (11.1%). Thus, high rates of success in KP-surgery can be achieved for CU and FAP-patients. But it has to be kept in mind, that KP is not in concurrence with IAP, it is also an alternative to Brooke-ileostomy. Patients with CC are less appropriate, because the necessity for repeated reoperations due to recurrent disease reduces significantly the overall benefit of the patients, even if continence is preserved.

[Technique and results of the ileoanal pouch after proctocolectomy].

Nowadays restorative proctocolectomy and ileal pouch-anal anastomosis represent the standard procedure in the treatment for ulcerative colitis and familial polyposis. Although various pouchdesigns are described, the J-pouch is the one most frequently used. This study reviewed 311 operations of restorative proctocolectomy and ileal pouch-anal anastomosis between January 82 and December 93. The indication was ulcerative colitis in 234 and familial polyposis in 77 cases. In 67% of the cases the standard two-stage procedure involving secondary ileostomy closure was chosen. Due to the complex nature of the operation, postoperative morbidity--which is higher for ulcerative colitis--must not be undermined. Complete exstirpation of the pouch was required in 4.2% of the patients with ulcerative colitis and in one case with familial polyposis. In 12.4% and 1.3% a severe pouchitis was found in ulcerative colitis and familial polyposis respectively. In general postoperative functional results were satisfactory. Continence was established in over 90% of the patients while the mean stool frequency was 6 per day.

Biochemical laboratory data in patients before and after restorative proctocolectomy. A study on 83 patients with a follow-up of 36 months.

From 1980 to 1987 ileoanal pouches were made in 83 patients. Specimen for a set of laboratory analyses were taken preoperatively, during the ileostomy and loop ileostomy periods and repeatedly during 36 months of follow-up. Cobalamine absorption and 14C-triolein breath tests were performed preoperatively in electively operated patients and postoperatively in all patients at 12 and 36 months. Low S-Ca was most pronounced preoperatively in patients who were to undergo acute colectomy (53%). Decreased S-Mg was detected in 16-36% at all stations. None had signs or symptoms of hypomagnesemia. Low S-albumin was rarely seen except for preoperatively in acute patients. Increased IgM was found in 40% of the patients during the loop ileostomy phase compared to 6-10% preoperatively. Substantially increased orosomucoid and/or haptoglobin were seen in patients during the functional periods but these increased values could not be correlated to episodes with acute pouchitis. High values of S-ALAT and ALP were much more frequent during the loop ileostomy periods than it was preoperatively and during pouch function. Low S-haemoglobin and/or iron were noticed during the functional period in 3-8% and 10-16%, respectively. Severe anaemia, due to iron deficiency developed in one patient after 2.5 years of pouch function. Preoperatively, slight decreases of S-B12 were found in 13% and impaired cobalamine absorption was revealed in 38% of the electively operated patients. The corresponding figures were 3% and 31% after 12 months and 5% and 36% after 36 months of follow-up, respectively. B12 substitution was given to in all 8 patients during the follow-ups. Lipid absorption was disturbed in 38% preoperatively and in 35% and 41% at 12 and 36 months, postoperatively.

[Radiological findings in patients with a J-shaped ileal reservoir].

This study comprised 116 patients with either ulcerative colitis or familial adenomatous polyposis, who were treated from 1983 to 1990. The patients were subjected to total colectomy followed by formation of an ileoanal reservoir (J-pouch). In a retrospective study the radiological findings of the J-pouch and the reservoir related complications are presented and a description of the applied technique for pouchography is given. A total of 513 radiological investigations were performed--median two per patient (range: 1-44). All 116 patients were subjected to pouchography while 59 patients additionally underwent conventional X-ray investigations, 42 patients were referred to ultrasound and ten patients to CT. Fourty-five percent of the patients presented no radiological complications at all. Patients with a normal primary pouchogram showed a significantly lower risk of long term complications related to the pouch. Pouchography was a useful method for excluding pouch pathology before restoring intestinal continuity as well as showing fistulas or cavities. In cases of leakage and especially stenosis and pouchitis pouchography was, however, less reliable. Ultrasound examination combined with CT-scan was beneficial in diagnosing abscesses.

[Transformations of ileo-rectal anastomosis into ileo-anal anastomosis in hemorrhagic rectocolitis. Indications and results].

In order to precise the indications and results of this procedure, we assessed 11 cases of transformation of ileorectal anastomosis (IRA) to ileal pouch-anal anastomosis (IPAA) in ulcerative colitis (UC). These 5 men and 6 women had undergone IRA at a mean age of 31 years, 33 months after the diagnosis of UC (range 3-120). Four of these IRA, excluded by an ileostomy, had never been in function: the cause was severe persistent proctitis in 2 cases and anastomotic leakage and peritonitis in 2 cases. The other 7 IRA had been in function during a mean period of 25 months (range 6-45) and were reoperated because of anal sepsis (1 case), low rectal stenosis (1 case), disabling proctitis (4 cases) and rectal dysplasia (1 case). No patient had specific pathologic signs of Crohn's disease. The 11 IPAA were complicated by pelvic sepsis in 3 cases; surgical drainage succeeded in 1 case, but the 2 others needed pouch excision and terminal ileostomy. The diagnosis of Crohn's disease was eventually made in these 2 patients. The 9 patients with functioning IPAA, at a mean follow-up of 40 months (range 12-60), had 5.2 stools per 24 h (range 2-12), 5 patients had no nocturnal stooling, and 6 had a perfect continence. One patient had disabling chronic pouchitis. In conclusion, proctectomy with IPAA is always feasible when a previous IRA for UC had failed or offers poor results, but should be rejected in case of anal involvement, as that may suggest Crohn's disease. This procedure is followed by similar functional results than after primary IPAA.

[The swiss experience of ileo-anal anastomosis with reservoir (AIA). Complications and functional results].

Two hundred and thirteen ileal pouch-anal anastomoses were performed in Switzerland from August 1980 to December 1991, 174 (82%) of them in 7 centres. One hundred and sixty four patients (77%) were operated for ulcerative colitis, 47 (22%) for familial polyposis and 2 others (1%) for another reason. A J pouch was created in 176 cases (83%), an S pouch in 35 cases (16%) and a W pouch in 2 cases (1%). Detailed results were available for 157 (74%) of the 213 operated patients: 81 females (52%) and 76 males (48%) with a mean age of 33.5 years (10-65). One hundred and twenty seven patients (81%) were operated for ulcerative colitis, including 42 as an emergency, and 30 (19%) for familial polyposis. One hundred patients (64%) developed complications which required one or several reoperations (laparotomy and/or perineal operation) in 64 cases (41%). Pouchitis was the most frequent complication (19%). Small bowel obstruction and pelvic abscess secondary to an anastomotic leak were the complications most frequently requiring second laparotomy with an incidence of 13% and 11%, respectively. The mean number of stools per 24 hours was 5.5 (2 to 14). 27% of patients passed one or several nocturnal stools every night, 27% occasionally, and 46% never. Occasional faecal incontinence was reported by 8 patients (6%) and 4 patients (3%) reported uncontrollable urgency. Nine patients retained a permanent ileostomy (failure rate: 6%).

An analysis of 50 cases of restorative proctocolectomy.

Restorative proctocolectomy with ileal pouch-anal anastomosis is clearly the operation of choice for ulcerative colitis and polyposis coli. Not so clear is the best way to perform this operation. The technique used at the University of Pittsburgh is described. Utilising a meticulous mucosectomy with the patient in a prone jack-knife position, the ileal pouch-anal anastomosis was successfully performed in a series of 50 consecutive patients which included six with orthotopic liver graft, nine with a prior Hartmann procedure, ten with fulminant colitis and six with cancer. All patients were fully continent of stools, and except for one, had a good functional result. Complications were minor and included pelvic sepsis (n = 2), ileostomy-related complications (n = 6) and pouchitis (n = 7).

[Fecal platelet-activating factor (PAF). A marker of digestive inflammatory disorders].

PAF (platelet-activating factor) is a phospholipid compound with harmful inflammatory effects on the gastrointestinal tract of animals. Recent studies have reported the presence of PAF in the stools of patients with inflammatory gut diseases such as Crohn's disease, ulcerative colitis, pouchitis and bacterial diarrhoea. PAF might be implicated in the occurrence and perpetuation of the digestive tract inflammatory symptoms observed in these diseases. The beneficial use of PAF antagonists in inflammatory diseases of the gastrointestinal tract deserves to be assessed.

Experience with restorative proctocolectomy in 201 patients.

Two hundred and one patients underwent restorative proctocolectomy between January 1985 and January 1993. The underlying disease was ulcerative colitis in 191 and familial adenomatous polyposis in ten patients. All patients had a J pouch and, except for 22 patients, total mucosectomy was performed. The procedure was technically successful in 200 cases (99.5%). There was no postoperative mortality, but two patients died soon afterwards due to unrelated causes (suicide, upper gastrointestinal bleeding). Early postoperative complications were observed in 33% of patients and 21% required reoperations, most often because of haemorrhage or pelvic sepsis. Late morbidity rate was 29% including reoperations in 31 patients (17%) and conversion to permanent ileostomy in five cases (2.5%). The most common late problems were anal sinus, stricture or fistula (11%) and episodic or chronic pouchitis (20%). The functional result was evaluated in 150 patients followed up for one year. the mean bowel frequency was 5.6 times in 24 hours, 19% of patients had minor anal soiling and 11% required a protective pad. It is concluded that restorative proctocolectomy has become the first choice for most patients with ulcerative colitis and familial adenomatous polyposis.

Factors favoring continence, the avoidance of a diverting ileostomy and small intestinal conservation in the ileoanal pouch operation.

Ileoanal pouch operation was performed upon 38 consecutive patients with ulcerative colitis (36 patients) or familial polyposis (two patients). Mucosectomy was avoided by rectal mobilization to the dentate line and eversion and stapling of the exteriorized anorectal junction with the dentate line in view. An 8 centimeter J pouch was stapled to the anorectal junction. A diverting ileostomy was not used in 34 of the 38 patients. Physicians independent of the operation evaluated patients postoperatively. Eighty-four percent of the patients did not experience any problems with incontinence or nocturnal spotting at one month postoperatively. No incontinence or nocturnal spotting was seen in any patient by one year postoperatively, with the exception of one patient with chronic pouchitis who had occasional nocturnal spotting that continues to improve. The average number of bowel movements per 24 hours was five at 12 months postoperatively, despite the small pouch. The mean distance from the dentate line to the ileoanal anastomosis was 0.9 +/- 0.5 centimeter (range of zero to 2 centimeters).

[Restorative proctocolectomy for ulcerative colitis and familial polyposis].

From 1987-1994 we performed 35 proctocolectomies with ileal pouch anal anastomosis. The indication for operation was ulcerative colitis in 29 and familial polyposis in 6. The mean ages at operation were 35 and 25 years, respectively. The most common postoperative complication was small bowel obstruction in 25% of the patients, requiring re-operation in half of them. The incidence of this complication may be reduced by operating in only 1 stage when possible, without creating a protective ileostomy. The second serious complication was pouchitis, in 17%, which was controlled by antibiotics. There has been no mortality. All patients, except for 2 with an S-shaped pouch, evacuate spontaneously a mean of 5 bowel movements a day. Continence was mildly impaired (usually night-staining of a pad) in 30% of patients in whom the pouch-anal anastomosis was performed after stripping the mucosa of the rectal remnant. In those in whom the pouch-anal anastomosis was performed by means of the double stapling technique, continence was almost completely preserved. We therefore recommend that proctocolectomy with ileal pouch-anal anastomosis be performed in 1 stage when possible, using the double stapling technique. Staged operation should be reserved for severely ill patients, or when stripping of the rectal mucosa is performed for familial polyposis and ulcerative colitis with severe dysplasia.

[Results of ileoanal reservoir surgery].

We report our surgical, late complications and functional outcome of 157 consecutive restorative proctocolectomies with an ileoanal J pouch at the Department of Surgery L, Arhus City Hospital. Nine patients had familial adenomatous polyposis, while 148 patients were operated for ulcerative colitis. All patients had a protecting ileostomy. There was no mortality. Surgical complications after J pouch: Six patients were reoperated, five due to intra-abdominal bleeding, one for ileus. There was only one pelvic abscess, and it was drained percutaneously. There were no fistulae, no anastomotic leakage and no early pouch removal. Surgical complications after ileostomy closure: Eight patients were reoperated; two due to wound infections, five for ileus and one due to a wound rupture. Late Complications: Four pouches were removed, due to incontinence, difficult evacuation, chronic pouchitis or Crohn's disease. There were three late pouchovaginal fistulae more than one year after surgery. Five patients had surgery for ileus, one for an intra-abdominal abscess, one for a perianal fistula and eight for incisional hernia. Functional outcome: One year after pouch surgery more than 90% of patients were satisfied with the operation, 2.2% had regretted and 3.6% were in doubt. The functional result was satisfactory in the majority of the patients, but 21.1% had one or more night evacuations and 13.9% had variable degrees of incontinence.

Image analysis in multisample biopsy after ileal pouch-anal anastomosis.

Pouchitis in ileal anal anastomosis represents an important clinical complication after restorative proctocolectomy. Acute and chronic inflammation of the reservoir is a frequent event sometimes associated with villous atrophy and colonic metaplasia. After ileal pouch anastomosis, twenty-one patients affected by ulcerative colitis were studied. An image analyzer CAS 200 (Becton Dickinson) was utilized to evaluate the DNA intranuclear content in every biopsy. In two cases abnormal DNA distribution was observed, and in one case a poliploid pattern was seen. Abnormal DNA distribution was also present in colonic metaplasia. Therefore, image analysis for the detection of DNA aneuploidy may be of additional value together with histologic parameters in follow up, in order to exclude transformation of the ileal mucosa in neoplastic epithelia.

Update on ileal pouch-anal anastomosis.

BACKGROUND: The surgical management of chronic ulcerative colitis and familial adenomatous polyposis was revolutionized in 1978 by the introduction of the ileal pouch-anal anastomosis, following proctolectomy and avoiding the necessity of a permanent stoma. AIMS: To analyze the current status of ileal pouch-anal anastomosis. METHOD: Factors such as age, concurrent medical conditions, and most importantly anal sphincter function are to be considered. Many technical aspects are reviewed such pouch design, mucosectomy, alternatives to perform the anastomosis, the use of diverting ileostomy, reservoir function and morbidity. RESULTS: Patient selection is of paramount importance to achieve good results. Many modifications to pouch design have been made in an attempt to improve functional results. Shorter mucosectomy is performed with hand-sutured anastomosis and double stapled anastomosis are the surgical alternatives to restore intestinal continuity. The use of diverting ileostomy is recommended in most patients to prevent pelvic sepsis. Mortality following ileal pouch-anal anastomosis is extremely unusual, however, morbidity is moderate. Small bowel obstruction, pelvic sepsis, fistula formation and pouchitis are the most common complications. Sexual dysfunction represents a major concern for younger patients in need of this kind of surgical treatment. However, its occurrence is rare. CONCLUSIONS: The ileal anal-pouch anastomosis has become the surgical treatment of choice for patients suffering from chronic ulcerative colitis and familial adenomatous polyposis. Primary advantages offered by this technique are that the disease is removed completely and adequate reservoir is restored and transanal defecation and fecal continence are reestablished, avoiding the necessity of a permanent stoma.

[Surgical indications and reconstructive techniques in the treatment of chronic forms of ulcerative rectocolitis. Review of the literature].

The authors have reviewed the literature particularly of the last decade, about surgical indications and timing in chronic ulcerative proctocolitis, also regarding the difficulties and the hazards the surgeon has to face depending on which type of chronic disease is considered. The various solutions for intestinal transit restoration have been reviewed, especially after the indications for terminal and continent ileostomy and for ileo-rectal anastomosis have been put aside, and total proctocolectomy with mucosectomy was advocated, with a special concern for assets and drawbacks of every type of ileal pouch. It is herein discussed the difference between the attitudes towards chronic active and recurrent ulcerative proctocolitis. The active form can't be cured with steroids and shows a greater risk of malignant transformation after 10-15 years of illness, insofar most cases (82%) in the long run need operation with this form that just often permits a one-stage surgery with mucosectomy, though. The commoner recurrent form is quite sensitive to steroids until these prove to be ineffective and surgery becomes mandatory (28% of cases). A two or three-stage surgery is advocated in this form with conservation of the rectum (mucosal fistula) as long as the acute phase is present, permitting only after its remission a restorative procedure with mucosectomy, which would be likely to be jeopardizing during the acute phase. The many designs of ileal reservoir do not differ indeed between each other as much in compliance as in maximum tolerable volume. The quadruple loop reservoir affords a volume approaching highly the original rectal volume, with better compliance and lesser frequency of bowel evacuations compared to other pouch designs. Some authors maintain that the functional outcome is independent of the reservoir shape. The anal continence basically depends upon the integrity of the internal sphincter, on the conservation of the anal inhibitory reflex and on the resting pressure. Muscular cuff is also mentioned with reference to anal function. Circular staplers have been employed for pouch-anal anastomosis 1-2 cm above the dentate line without mucosectomy. The stapled pouch-anal anastomosis entails a damage to the internal sphincter by some authors on the contrary a better sphincter function by others, compared to hand-sewn anastomosis with mucosectomy. Trials are needed to compare the risk of rectocolitis recurrence or malignancy after hand-sewn pouch-anal anastomosis with mucosectomy and after stapled anastomosis without mucosectomy. Postoperative complications are also herein discussed, with a special regard to pouchitis and its various aetiologic factors in early and late postoperative course.

[Proctocolectomy with ileoanal anastomosis: morbidity and functional results in patients with and without colorectal cancer].

BACKGROUND: The elective prophylaxis for colorectal cancer in patients with familial adenomatous polyposis (FAP) or with ulcerative colitis (UC) is the RPIPAA. AIMS: To evaluate the functional results and the morbidity rate in patients who underwent restorative proctocolectomy with ileal-pouch anal anastomosis (RPIPAA). METHODS: All patient underwent a proctocolectomy with a J reservoir, ileal pouch-anal anastomosis. RESULTS: There were 8 males and 3 females with a mean age of 31 years; the diagnoses were: FAP (n = 4); FAP + colorectal cancer (n = 3); metachronous colorectal cancer (n = 3) and UC + right colon cancer (n = 1). The average surgical time and the intraoperative bleeding were 5.6 h and 600 ml respectively. There were no operative deaths. The surgical complications were: section of left urether (n = 1); hemoperitoneum of 1,200 ml (n = 1); minor pelvic sepsis (n = 1); ileoanal stenosis (n = 1) and pouchitis (n = 1). Tumor staging was: Dukes A (n = 2), B1 (n = 1), B2 (n = 4). The mean follow-up was 22 months. Average of stools at the 3rd, 6th and 12th month was: 7.4, 5.6 and 3.8 respectively. Sexual function was: normal (n = 8), retrograde ejaculation (n = 2) and impotence (n = 1). The use of antidiarrheal agents in 24 hours at the third, sixth and twelfth month was 3, 2 and .8 respectively. CONCLUSIONS: The RPIPAA is associated with a low rate of morbidity and good functional results, similar to previously published results. However, these results should be taken with caution due to the small, selected and retrospective nature of the study.

Outcome of 200 restorative proctocolectomy operations: the John Radcliffe Hospital experience.

BACKGROUND: Restorative proctocolectomy is now the operation of choice for the definitive management of ulcerative colitis and familial adenomatous polyposis (FAP). METHODS: A total of 200 patients (117 male, 83 female) underwent restorative proctocolectomy over a 12-year period. Information in a dedicated prospective database was supplemented by chart review. Some 177 had ulcerative colitis, 13 had indeterminate colitis and seven had FAP. Pouch designs were two-loop J (n = 142), four-loop W (n = 45) and three-loop S (n = 13). The majority (73.5 per cent) had a stapled ileoanal anastomosis and 139 patients had a defunctioning ileostomy. RESULTS: There were no deaths. Early morbidity (less than 30 days after operation) included 76 complications in 71 patients (35.5 per cent), of which 35 were related to the pouch itself. Long-term follow-up data were available for 196 patients at a median of 27 months. Sixteen pouches (8.0 per cent) have been excised. Mean daytime frequency was 4.5 (range 1-15). Of 175 patients with colitis, 42 (24.0 per cent) had one or more episodes of pouchitis. CONCLUSION: Continuous improvements in operative technique have simplified the procedure, and functional results, although variable, have generally been acceptable.

Quantification of fecal alpha 1-antitrypsin excretion for assessment of inflammatory bowel diseases.

Determination of fecal excretion of the serum proteinase inhibitor alpha(1)-antitrypsin (AAT) is established for quantification of intestinal protein loss. It was demonstrated to be increased both in quiescent and in active inflammatory bowel diseases (IBD, Crohn's disease and ulcerative colitis). The (patho)physiological rationale for measuring fecal AAT excretion and its role in the diagnostic and prognostic assessment of these disorders will be critically reviewed. Experimental and clinical data were selected from computerized MEDLINE literature search, manual review of bibliographies, and personal experiences of the authors. In IBD patients, fecal AAT excretion corresponds to gross assessment of clinical disease activity, endoscopic degree of intestinal inflammation, and any response to treatment. It appears to be an early indicator of subclinical bowel disease and its imminent exacerbation. However, there is neither strict correlation to summarizing clinical disease activity indices, nor to extent or location of intestinal inflammation. Fecal AAT excretion was also found to be elevated in active pouchitis, and to correlate to its severity. In summary, estimation of fecal AAT excretion is a sensitive, but non-specific parameter reflecting enteric inflammation in IBD individuals. It proved to be an independent supplementary variable for monitoring their intestinal disease activity, with some predictive value for their forthcoming clinical course.
