[Esophagus: postoperative aspects].

Although endoscopy has replaced radiology for the diagnosis of diseases of the oesophagus, postoperative imaging still remains essential. The radiological investigation depends on the initial disease, and its technique is adapted to the suspected complication and the type of operation performed. Immediately postoperatively, a barium swallow allows verification of the surgery before reintroducing food. The early diagnosis of possible complications is based on the barium swallow and CT scan. At a longer interval after the operation, medical imaging, particularly barium swallow, allows anatomical and functional postoperative surveillance. Relapses of the initial disease, particularly neoplastic recurrences can be distinguished from an intercurrent disease or a mechanical complication due to the operation.

[Results of ileoanal anastomosis with mucosectomy and "J" pouch in hemorrhagic rectocolitis].

The aim of this study was to assess the results of ileal "J" pouch-anal anastomosis in ulcerative colitis. One hundred and fifty six patients operated on between 1983 and 1991 for ulcerative colitis were followed-up prospectively since the surgical procedure with a mean of 29 +/- 16 months (range: 6 to 92 months). There was no postoperative death. Forty-four patients (28%) presented 48 post-operative complications and 14 (9%) were reoperated. Twenty-five patients (16%) were reoperated because of a late complication. Three pouches had to be removed for untreatable fistulas which appeared to be related to a Crohn's disease in 2 cases; the reestablishment of a diverting loop ileostomy was mandatory in 2 further patients for anoperineal sepsis. The mean stool frequency at 1 year was 4.5 +/- 1.9; 40% of patients did not have nocturnal stooling. Daytime and nighttime continence were normal in 90.7% and 77.5% of cases respectively, 87% of patients considered their social life improved by the surgical cure of the disease. The results observed 5 years after the surgical procedure in 37 patients were similar to those observed at 1 year. Twenty-five patients (16%) presented one or several episodes of pouchitis, including 5 cases of chronic pouchitis. It is concluded that the treatment of ulcrerative colitis, ileal "J" pouch-anal anastomosis, is a safe and effective procedure which provides good functional results.

[Entero-enteral fistulas in Crohn disease: radical or conservative surgical treatment of the "victim" segment?].

OBJECTIVES AND METHODS: Entero-enteral fistulas join a segment affected by Crohn's disease to another which becomes a drainage route and a "victim" of the process. Surgical treatment can be radical (extensive resection of both segments) or conservative (resection of involved bowel and conservation of the "victim"). Fifty-nine patients operated on for Crohn's disease and having 80 entero-enteral fistulas were retrospectively studied. RESULTS: Main surgical indications were symptomatic intestinal stenosis (56%) or abdominal mass (20%) unresponsive to medical treatment. Fistula was discovered during operation in 33 patients (56%). Conservative treatment was performed in 39 fistulas (49%). In 41 fistulas (51%), proximity of fistulous ends, or Crohn's disease's extension, led to radical treatment. In 66 fistulas (82.5%), histologic examination revealed that Crohn's disease affected only one bowel segment, the other demonstrating only non specific features; in the 14 remaining fistulas (17.5%), Crohn's disease affected both segments. CONCLUSIONS: The clinical presentation of entero-enteral fistulas (non-specific symptoms, frequent peroperative diagnosis), their pathological features (victim segment often free of Crohn's disease) plead for a conservative surgical approach, i.e. adapted to real bowel involvement by Crohn's disease.

Function of ileal J pouch-anal anastomosis in patients with familial adenomatous polyposis.

Pouch function after proctocolectomy and ileal J pouch-anal anastomosis was assessed at 1 and 5 years in 41 patients with familial adenomatous polyposis. The mean(s.d.) stool frequency per 24 h decreased from 4.4(1.7) to 3.9(1.8) (P < 0.05), the mean(s.d.) nocturnal stool frequency fell from 0.6(1.0) to 0.3(0.6) (P < 0.05), and the number of patients having nocturnal bowel movements decreased from 16 to seven (P < 0.05). At 5 years, only one patient still followed a strict diet (versus ten at 1 year, P < 0.05) and only two needed antidiarrhoeal medication (versus ten at 1 year, P < 0.05). There were no episodes of pouchitis or late reservoir-related complications. The function of ileal pouch-anal anastomosis improves over time in patients with familial adenomatous polyposis.

Surgical polypectomy of duodenal adenomas in familial adenomatous polyposis: experience of two European centres.

Between 1978 and 1988, 12 patients with familial adenomatous polyposis (FAP) and severe duodenal polyposis underwent duodenotomy and duodenal polypectomy. The patients were from two separate institutions; all were women, with a mean age of 45.6 (range 25-62) years at the time of duodenotomy. Recurrent duodenal polyposis was detected at endoscopy in all 12 patients, at a mean of 13.3 (range 5-36) months after duodenotomy. All patients had moderate to severe duodenal polyposis at the time of the last endoscopic examination. Local excision of duodenal adenomas is an unsatisfactory treatment option in those with FAP. The ideal management of patients with FAP who have severe duodenal polyposis remains uncertain.

Secondary proctectomy and ileal pouch-anal anastomosis after ileorectal anastomosis for familial adenomatous polyposis.

Conversion of ileorectal anastomosis to ileal pouch-anal anastomosis (IPAA) was indicated in 29 patients with familial adenomatous polyposis but technically impossible in three because of unsuspected pelvic desmoid tumours. There was no operative mortality and overall postoperative morbidity and late complication rates were no different from those in a group of 120 patients who underwent IPAA as a first operative procedure. Unsuspected adenocarcinoma (one invasive, three in situ) was found in four patients. The functional results in patients with IPAA did not differ from those of ileorectal anastomosis before conversion or from those obtained after IPAA as a first-choice procedure. Secondary proctectomy and IPAA can be safely offered to patients with ileorectal anastomosis and a high risk of rectal cancer.

Pancreatico-duodenectomy for cancer and precancer in familial adenomatous polyposis.

Duodenal adenomas occur in most patients with familial adenomatous polyposis and their potential for malignant transformation appears to be high. In case of rapid polyp growth or severe dysplasia, the place of surgical resection is controversial. We report 2 patients with familial adenomatous polyposis who underwent radical pancreatico duodenectomy several years after the treatment of colonic polyposis. The first patient had a pancreaticoduodenal resection performed for a duodenal adenocarcinoma. The second patient had a pancreaticoduodenal resection with pylorus preservation and pancreatogastric anastomosis performed for recurrent duodenal adenomas with severe dysplasia. Both remained alive without recurrence and with a good functional outcome 24 and 28 months after operation. We conclude that radical prophylactic surgery may be indicated for patients with familial adenomatous polyposis who have severe duodenal polyposis.

Previous subtotal colectomy with ileostomy and sigmoidostomy improves the morbidity and early functional results after ileal pouch-anal anastomosis in ulcerative colitis.

The aim of this work was to study the effects of previous subtotal colectomy (STC) with ileostomy and sigmoidostomy on the outcome of ileal J-pouch-anal anastomosis (IPAA) in patients with acute ulcerative colitis. Between 1983 and 1991, we conducted a prospective, nonrandomized study of 156 patients who underwent IPAA in our center. Fifty-five patients (34.3 percent) had undergone STC with ileostomy and sigmoidostomy for either severe acute colitis (36.5 percent of cases) or nonresolving acute colitis (63.5 percent) up to six months before IPAA with covering ileostomy. There were no perioperative deaths; six patients (11 percent) developed complications requiring reoperation (three cases of pelvic sepsis, two occlusions, and one stenosis of the ileostomy). IPAA was successfully carried out at a later stage in all cases. The results of IPAA in these patients were compared with those in 78 patients who underwent the classical two-stage IPAA procedure. The rates of pelvic sepsis and postoperative occlusion were lower in the subgroup of patients who underwent the three-step procedure. Three months after closure of the ileostomy, the mean number of daily stools was significantly lower in the patients who had undergone prior STC (5.09 vs. 5.9), but there was no significant difference between the two groups with regard to diurnal and nocturnal continence, the need to wear a pad, discrimination between gas and stools, or the use of antidiarrheal medication. In addition, there was no significant difference at one year in terms of functional parameters. We conclude that STC is a simple and safe procedure for the treatment of a severe attack of colitis and that it does not compromise the results of later IPAA. Because it does not increase the morbidity of subsequent IPAA and is associated with more rapid functional recovery, STC appears to be suitable for the treatment of patients with nonresolving acute colitis before the onset of malnutrition or steroid dependency.

A report of forty-four instances of pancreaticoduodenal resection in patients more than seventy years of age.

Between January 1970 and December 1990, 223 patients underwent pancreaticoduodenal resection for pancreatic or periampullary tumors. Forty-four of these patients were 70 years of age or older and 179 patients were less than 70 years of age. In the older group, 27 patients were operated upon after 1986. The overall operative mortality rate was 9.0 percent and 2.5 percent during the last five years. The overall operative mortality rate was 4.5 percent in patients more than 70 years of age and 10 percent in those less than 70 years of age. The overall operative morbidity rate was 35 percent; 36 percent in patients more than 70 years of age and 35 percent in those less than 70 years of age. Survival was related to tumor histologic factors. For carcinoma of the pancreas, the survival rate at five years was 17 percent in patients more than 70 years of age and 19 percent in patients less than 70 years of age. For the ampullary carcinoma, the survival rate at five years was 38 percent in patients more than 70 years of age and 45 percent in patients less than 70 years of age. It can be concluded that, in a selected group, age is not a limiting factor for pancreaticoduodenal resection.

[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.

[Ileo-anal anastomosis in familial adenomatous polyposis: procedure of choice?].

Surgical treatment of familial adenomatous polyposis (FAP) remains controversial. The arguments in favour of ileal pouch-anal anastomosis (IPAA) are well known. All the premalignant mucosa is removed and the risk of rectal carcinoma is avoided. Recent studies have compared results of IPAA and ileo rectal anastomosis (IRA). Morbidity is higher after IPAA, but it does not seem to influence the functional result, and it has to be compared with discomfort of subsequent rectal fulgurations. Functional result of these two procedures is very similar. The risk of occurrence of desmoid tumor is also similar. But desmoid tumor can interfere with the planned treatment and conversion of IRA to IPAA is not always feasible. Furthermore, it is suggested that desmoid tumour could be promoted by iterative surgical trauma. We conclude that it is preferable to perform directly the best and definitive operation and that IPAA is for us the procedure of choice in FAP, except in case of low rectal cancer or extensive colic cancer.

[Total colectomy and ileorectal anastomosis in Crohn's colitis. Functional results and recurrence factors (83 cases)].

Eighty-three consecutive patients (38 men, 45 women) underwent colectomy and ileorectal anastomosis (IRA) for Crohn's colitis between 1960 and 1988. The mean age at the time of IRA was 28.5 years after a mean interval of four years from diagnosis. At the time of IRA, 31 patients had proctitis, while 25 had perianal disease. Two patients died postoperatively. Postoperative complications appeared in 21 cases (25.3%) including 7 anastomotic leaks (13.2%). Leakage did not imply IRA compromise and the diverting ileostomy did not decrease the risk of preservation of the ileorectal anastomosis. With a mean follow-up of 8 years after IRA, among the 81 surviving patients, it was necessary to retain the stomy in five, 24 required exclusion or excision of their IRA (10 defunctioning ileostomies, 14 proctectomies) and 52 still had a functioning IRA at follow-up (64.2%). Among the 43 recurrences (53%), 21 underwent reoperation. The mean interval between IRA and recurrence was 2.2 years. The cumulative rate of recurrence reached 47% at 5 years and 57% at 10 years. Fifty percent of the patients still had a functioning IRA and were satisfied. Preoperative ileal lesions affected the functional results of the IRA and the recurrence rate. Development of ileal, rectal or anal disease after IRA significantly increased the risk of exclusion of the rectum but did not require suppression of anal function. Patients under 30 years of age or patients suffering for more than 5 years had poorer functional results and more frequent reoperations at 5 years. Rectal preservation after IRA may be proposed with success to patients with a healthy rectum or with minimal or moderate proctitis, even if there is perianal disease that could be safely treated before IRA. In this last setting, the patient has to be informed of the risk of rectal preservation and the possible risk of requiring ulterior proctectomy.

Operation and abdominal desmoid tumors in familial adenomatous polyposis.

Abdominal desmoid tumors (ADT) have become an important problem because of the increased survival of patients with familial adenomatous polyposis (FAP). Of 240 patients operated upon for FAP between 1978 and 1991, 29 (16 men and 13 women) had ADT. Diagnosis was made at laparotomy in 19 patients, while an abdominal mass or intestinal obstruction was the principal cause of discovery in the ten remaining patients. Twenty ADT were discovered after a previous laparotomy performed an average of three years earlier. Nine ADT occurred in 146 patients who had previously undergone a coloproctectomy and ileal pouch-anal anastomosis and eight occurred in 74 patients who had abdominal colectomy and ileorectal anastomosis. Desmoid tumors were responsible for eight instances of intestinal obstruction and one instance of small intestinal perforation. One death was directly related to ADT. In four of nine patients, ADT was responsible for a deterioration of the functional results of ileoanal anastomosis, but pouch removal was not necessary. Conversion of ileorectal anastomosis to ileoanal anastomosis and excision of carcinomas that occur in the residual rectum after ileorectal anastomosis were impossible because of ADT in three and two patients, respectively. Complete surgical removal of the tumor was possible in seven patients only and four patients had a recurrence. None of the medical therapies used (sulindac, tamoxifen and chemotherapy) were effective. The results of this study confirm the high incidence, severity and absence of effective treatment of ADT in FAP. Desmoid tumors occurring after ileorectal anastomosis seem to be more severe than after ileoanal anastomosis because, in the former instance, they may interfere with the further management of the rectal stump.

[Colonic complications of acute necrotizing pancreatitis].

Among 126 patients operated upon for acute necrotizing pancreatitis in our department over a 10-year period starting in November 1979, 17 had a colonic resection. Colectomy was made mandatory by a necrotic or ischaemic appearance (12 cases, including 3 bowel perforations), an isolated perforation (2 cases) or extensive fat necrosis of the pericolonic atmosphere (3 cases). The hospital mortality was 5 out of the 17 cases. In 6 patients, the pathological results suggested that colonic resection was unnecessary. Since May 1988, a diverting loop ileostomy has been performed whenever colonic viability was found to be dubious at laparotomy. After this policy was introduced no case of secondary colonic complication was encountered. Nevertheless, there still are "abusive" colectomies unjustified by the pathology. Their number should be reduced by a more cautious indication of colonic resection in acute necrotizing pancreatitis.

[Value of screening of familial adenomatous polyposis for the prevention of colorectal cancer].

Familial adenomatous polyposis coli is a hereditary autosomal dominant disease which spontaneously and inevitably leads to degeneration of colorectal adenomas and requires preventive surgical treatment. The aim of this study was to evaluate the age of colorectal degeneration and the need for a screening technique in family members. Between 1983 and 1989, 141 patients were treated for familial adenomatous polyposis in our surgical center. Mean age at surgery was 32 years and 64 patients (45.4 percent) had a colorectal carcinoma. Thirty had an in situ tumor (mean age: 30 years) and 34 had an invasive adenocarcinoma (mean age: 45 years), 7 of whom died of their cancer. No colonic cancer was found in patients younger than 20. Thirty-eight percent of the patients under 40 years of age, 73 percent of the patients older than 40 years and 81 percent of those older than 50 had an adenocarcinoma. Fifty percent of the patients with carcinoma were younger than 40 years and 7 percent were less than 25 years old. Seventy-one patients were symptomatic at the time of operation (mean age: 40 years), 32 (45 percent) had a colonic cancer. In 70 patients, familial adenomatous polyposis was detected by screening (mean age: 24) and 2.8 percent had a colonic carcinoma. We conclude that the age-related risk of developing colonic carcinoma requires prophylactic surgery in asymptomatic patients before 20 years of age, and that routine familial screening would be of some benefit.

[Comparison of functional results of ileorectal and ileo-anal anastomoses in familial adenomatous polyposis. Conversions of ileorectal anastomoses into ileo-anal anastomoses].

The aim of this study was to compare the functional results of ileo-rectal anastomosis and ileal pouch-anal anastomosis in a group of patients with familial adenomatous polyposis who had conversion of a ileorectostomy into a ileal pouch-anal anastomosis. In 2 cases (8.3 percent), the conversion was impossible because of abdominal desmoid tumors. For the remaining 21 patients, with more than 1 year follow-up, the number of bowel movements per 24 hours was 3.8 +/- 0.2 before and 4.6 +/- 0.3 after conversion. Daytime and nighttime continence and sensation of the need to defecate were unchanged. The number of patients having nocturnal bowel movements were higher after the pouch procedure (40 vs 10.5 percent). After ileorectostomy and after conversion, 89.5 and 80 percent of the patients had good functional results respectively. Ninety percent of the patients said that results were unchanged or improved after the conversion. In familial adenomatous polyposis the functional results of ileal pouch-anal anastomosis are similar to those of ileorectostomy but the first procedure eradicates the risk of rectal cancer. A conversion to ileal pouch-anal anastomosis should to be proposed to patients with ileorectostomy and at high risk for rectal cancer.

[Diverting loop ileostomy, effective prevention of colonic complications in necrotizing acute pancreatitis].

The operative diagnosis of colonic ischaemia in association with acute necrotizing pancreatitis (ANP) may be difficult in the absence of unequivocal transmural necrosis or perforation. We introduced in May 1988 a new policy whereby, when colonic viability was dubious, resection was avoided and a diverting loop ileostopy (DLI) was performed. If necrosectomy led to extensive mobilization of the splenic flexure with a capillary drainage system placed in close contact, a DLI was again performed. Colectomy was only performed for unequivocal transmural necrosis. Among 30 patients operated on for ANP, 12 underwent DLI. This policy allowed us to spare potentially ischaemic colons. No secondary colonic complication occurred and there was no rise in the mortality rate. Among patients whose colon was kept in circuit there were bouts of bowel distension and unexplained bacteriemia ultimately leading to death from multiorgan failure. When colonic viability is dubious and when drainage is brought up in close contact with the bowel wall DLI might allow colonic resection to be avoided. In our experience DLI also seemed to prevent secondary colonic complications.
