The management of acute distal colonic obstruction remains controversial. The advent of intraoperative colonic irrigation has allowed primary anastomosis to be performed in obstructed bowel. Fifteen patients, with acute distal obstruction due to carcinoma, diverticulitis or sigmoid volvulus were managed by primary resection and anastomosis. There were two leaks (14 percent) and the duration of operation was prolonged. In an experimental study of anastomotic healing after acute obstruction, intraoperative irrigation improved early anastomotic colonic collagen content (P less than 0.02) and perianastomotic proximal and distal collagen content (P less than 0.002, P less than 0.05). Intraoperative lavage is a useful technique to permit safer primary resection and anastomosis in obstructed colon.

The indications for colonoscopy in a recent consecutive series of 232 examinations were analyzed. Of these examinations, 30 (13%) were performed for nontoxic megacolon. Nontoxic megacolon is defined as severe dilatation of a segment or the entire colon unaccompanied by signs or symptoms of colon toxicity. Mechanical factors (volvulus, anastomosis, diverticulosis, carcinoma) were responsible for the nontoxic megacolon in 13 of these patients. Nontoxic megacolon was classified as secondary to acute pseudoobstruction (Ogilvie's syndrome, pancolonic megacolon, acute myxedema ileus) in 17 patients. All patients were being evaluated for possible exploratory celiotomy to prevent perforation of the colon because of the massive colonic distention. Colonoscopic examination was performed at the bedside or in the intensive care unit for 11 of 30 patients. No bowel preparation was used. Evacuation of air and fecal material was more efficiently accomplished by use of an external suction device attached to the biopsy part of the endoscope. For 12 of the 13 patients who had a mechanical basis for their nontoxic megacolon the colon was successfully decompressed. All 17 patients with acute pseudoobstruction were successfully treated. There were no iatrogenic perforations. Possible emergency operation was avoided for all patients except one who had a cecal volvulus. Colonoscopy should be considered as the initial treatment for nontoxic megacolon prior to surgical intervention.

This study reports the use of an intraoperative antegrade colonic irrigation in the management of left-sided large bowel obstruction requiring emergency surgery. 35 consecutive patients had primary bowel resection with immediate anastomosis (without colostomy) after intraoperative antegrade colonic irrigation. The cause of the obstruction was large bowel carcinoma in 26, diverticulitis in seven and volvulus in two cases. There were two post-operative deaths (5.7%). No digestive fistula was observed. The results of this study suggest that intraoperative colonic irrigation is an effective method, enabling the surgeon to perform a primary anastomosis with reasonable safety after emergency resection of selected distal colonic lesions.

The causes of melena or hematochezia in 48 pediatric patients were examined. Malrotation with volvulus was an important cause of hemorrhage during the newborn period, and intussusception was very typical in patients aged from 1 month to 1 year. Polyps of the rectum and colon were the most common causes of melena or hematochezia in patients older than 1 year. No cause of melena or hematochezia could be identified in 11 children. Ten patients have remained in good health with no further episodes of melena or hematochezia. Localized multiple polyps of the rectum with focal carcinoma were detected in only one patient. In general, although no further investigation is required after detection of the cause of bleeding and its successful treatment, it should be kept in mind that gastrointestinal malignancy can occur in children.

Laparoscopic treatment of small intestinal obstruction is associated with immediate advantages and it may be expected that the recurrence rate will be decreased because of the reduction of wound scars. Between september 1989 and september 1991, 25 patients (16 men and 9 women), mean age 53.8 years, underwent initial laparoscopy for acute small intestinal obstruction. These patients had undergone a total of 43 (1.7 per patient) laparotomies an average of 13 years previously. One patient had never been operated on, 13 had one previous laparotomy, five had two, four had three, and two had four previous laparotomies. Laparoscopic treatment of intestinal obstruction was possible in nine cases including three cases of bands and six cases of adhesions. In sixteen cases, laparoscopy had to be completed by laparotomy, 13 immediately and 3 secondarily. The cause of immediate failure was the impossibility of finding and/or treating the cause in seven instances, four cases of intestinal wounds, on case of intestinal necrosis which required resection, and one case of missed right colonic carcinoma. The cause of secondary failure were incomplete release of adhesions, volvulus, and missed left colonic carcinoma in one case each. Mean hospital stay and postoperative ileus were significantly shorter in the "laparoscopy" group than in the laparoscopy + laparotomy group (p < 0.001). Two complications, with one death, were noted in the laparoscopy + laparotomy group. In conclusion, laparoscopic treatment of intestinal obstruction seems possible but in less than half of cases. Failures are related to the difficulty with which the abdomen may be explored. Laparoscopic treatment should not be pursued in case of problems.(ABSTRACT TRUNCATED AT 250 WORDS)

The results of 37 consecutive cases of Hartmann's procedure over a 5-year period (1985-1990) were reviewed. The series consisted of 27 emergency procedures (11 diverticular disease, 13 carcinoma, two trauma and one sigmoid volvulus) and ten elective procedures (nine carcinoma and one peridiverticular abscess). The indications for emergency procedures were obstruction and perforation. All patients presented with faecal peritonitis owing to colonic perforation. The mean (range) age was 79.4 (34-90) years. The postoperative mortality rate was 30 per cent overall (11 of 37), 33 per cent (four of 12) in the diverticulitis group, 23 per cent (five of 22) in the carcinoma group, and 100 per cent in the iatrogenic trauma group. Death was mainly due to sepsis (82 per cent). Postoperative complications were mainly wound infections, which occurred in 43 per cent (16 of 37) cases. In 25 per cent of the surviving patients, re-establishment of continuity was performed in three of 17 (18 per cent) of the carcinoma group and three of seven (43 per cent) of the diverticulitis group. No attempt at restoration of intestinal continuity was made in six cases due to medical risk in two, extensive carcinoma in two and local recurrence with metastatic disease in two. Three patients refused all further intervention. There were no postoperative deaths after the restoration of continuity. This series reflects the severity of the pathology in this high risk group of patients. However, the operation can be life-saving for a selected group of patients and offers good palliation for advanced colorectal tumours.

In a prospective study, we investigated the value of high resolution sonography for the imaging diagnosis of colonic diverticulitis. A total of 161 patients with abdominal complaints on account of which acute diverticulitis entered into differential diagnosis were included in the study. 74 of these finally had proven colonic diverticulitis (prevalence, 46%). The results of intestinal sonography and the working diagnoses on admission were evaluated on the basis of final diagnoses. According to history, symptoms, and clinical findings on admission, the working diagnosis of diverticulitis was graded as being "highly suspect" in 26 (35.1%) of these 74 diverticulitis patients, as being "possible/equivocal" in 36 (48.6%), and as being "very unlikely" in in 12 (16.2%). In 7 (9.5%) patients with diverticulitis, the diagnosis was clinically unsuspected and primarily established by ultrasound. Overall accuracy, sensitivity, and specificity of intestinal sonography with regard to the diagnosis of diverticulitis were 97.5%, 98.6%, and 96.5%, respectively. There were three false positive ultrasonic diagnoses of diverticulitis which were made in two patients with perforated carcinoma of the sigmoid and in one case of sigmoid volvulus (positive predictive value, 96%). Ultrasound failed to visualize sigmoid diverticulitis with perforation in one patient (negative predictive value, 98%). In 19 out of 20 patients with abdominal abscesses (prevalence, 12.4%), the diagnoses were established by means of sonography. Nine of these patients with abscesses initially were treated by ultrasound guided percutaneous drainage enabling elective surgery. In 26 (70%) of 36 patients with morphological disorders other than diverticulitis, ultrasound findings substantially added for the definite diagnoses.(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatodiaphragmatic interposition of the intestine is a rare anomaly (0.025 to 0.28 percent of the general population) described by Chilaiditi in 1911 and often believed to be of irrelevant clinical interest. To the contrary, recent studies stated that this syndrome is a potential source of abdominal problems requiring emergency or elective operation. From a retrospective analysis of records since 1976, four instances of Chilaiditi's syndrome have been found (three males and one female). Interposition of the proximal transverse colon was found in three patients and the small intestine in one patient. The findings of plain roentgenograms of the chest were determinants for diagnosis in three patients. In one patient, a barium meal was given to obtain a better definition. Two patients were admitted for malignant neoplasms (metastatic carcinoma of the breast, carcinoma of the gastrointestinal tract and cirrhosis of the liver) and died within a few months. The other two patients complained of abdominal pain. Patient No. 4 had gastric volvulus. Chilaiditi's syndrome was diagnosed intraoperatively in that patient and a surgical treatment with hepatopexy was performed, by suturing the falciform, the coronaria ligament and the anterior margin of the liver to the diaphragm with interrupted absorbable stitches. After a two year follow-up evaluation, this patient is as well as the patient who underwent medical therapy. Volvulus of the stomach, as was found in Patient No. 4, is an unusual condition and, to our knowledge, the patient is the second reported instance.

Morbidity and mortality have been evaluated in 238 patients with acute large bowel obstruction admitted over a ten year period. In two thirds, the cause of obstruction was a primary colonic carcinoma. Most of these patients (61%) had advanced disease and were over 70 years of age. Volvulus and cancer recurrences each accounted for 10%, and diverticulitis for eight percent. An overall mortality of 24% was found. Of 115 patients who had the obstructing lesion--primary carcinoma or diverticulitis--resected, a mortality of 8.7 was seen, higher for primary (14.9%) than for staged (4.4%) resections, in contrast the latter had a significantly longer hospital stay, 30 days as against 17 days when a primary resection was performed. Six non-lethal anastomotic leaks occurred. It is concluded, that patients with large bowel obstruction, most often caused by a colorectal carcinoma, are a high-risk group. In this retrospective study staged procedure compared with primary resection had lowest morbidity and mortality.

Between June 1, 1990 and December 31, 1996, 58 consecutive patients with unprepared colons were urgently explored for nontraumatic disease with intent to proceed with primary left-sided colonic anastomosis. Unprotected anastomoses were not attempted in 15 patients. The causes of exclusion included preoperative and intraoperative shock in three patients, and three patients were on long-term high-dose steroids, four had gross fecal contamination of the peritoneal cavity, four had large pelvic abscesses, and one had ischemic colitis. All 43 patients undergoing anastomosis without protective colostomy had stapled anastomoses. Indications included complicated diverticular disease in 32 cases. There were nine cases of obstruction from colorectal carcinoma and one obstruction due to sigmoid volvulus. There was one case of perforation from pseudomembranous enterocolitis. The most common complications were: atelectasis in nine cases, wound infection in two cases, and prolonged ileus in two cases. Pelvic abscess occurred in one case. There was one wound dehiscence. There was one anastomotic dehiscence, and there was no mortality. Operative time averaged 85 minutes and hospital length of stay 9.7 days. Primary anastomosis of the unprepared left colon is safe in most urgent and emergent situations, thus avoiding the significant morbidity and cost of colostomy closure.
