Flexible fiberoptic gastrointestinal endoscopy has greatly simplified the diagnosis and treatment of colonic volvulus. The management of 39 patients with colonic volvulus treated over 9 years was reviewed. Five per cent were treated with rectal tube decompression alone, 23% were treated with either sigmoidoscopic or colonoscopic reduction, and 26% were treated exclusively with operation. Endoscopic reduction was attempted in nearly half of the patients in preparation for operation. Recurrent volvulus occurred in 57% of patients initially treated with endoscopic reduction alone. Sigmoidoscopic examination did not confirm the diagnosis in 24% of instances in which it was used, although colonoscopy was always diagnostic. The overall mortality rate was 8%, but increased to 25% in patients with gangrene of the colon. Three patients who later proved to have gangrene of the colon had a normal initial sigmoidoscopic examination. Two of these patients died of intra-abdominal sepsis from a perforated colon. In five patients an accurate endoscopic diagnosis of gangrene prompted immediate exploration. None of these patients died. Endoscopy is a safe and effective diagnostic tool for the initial evaluation of patients with suspected colon volvulus. In addition, endoscopy may result in therapeutic decompression and may provide visual assessment of the viability of the bowel mucosa, thus assisting in the timing of appropriate operative treatment.

Colonic pseudo-obstruction (Ogilvie's syndrome) may occur in surgical patients, particularly those who have had orthopedic or blunt trauma, have uremia or diabetes, have complex metabolic or cardiac failure, have metastatic cancer involving the lymph nodes and neural tissue, or are addicted to narcotics. Although a single true cause has not been identified by fulfilling Koch's postulates, the clinical pattern has been recognized in a variety of surgical patients, and this pattern must be distinguished from true obstruction of the colon. Tumor or internal hernia may constitute an obstruction, but the important differential diagnosis of cecal volvulus must be excluded. Ischemic colitis may be confused with Ogilvie's syndrome or may follow it. Gangrene, infarction, and perforation may ensue as colon diameter increases and particularly if cecal distention reaches above 14 cm. This arbitrary number for cecal dilatation should not be awaited before treatment is instituted if signs of devitalization of the gut or peritoneal signs have developed in the patient. Treatment has changed recently with the widespread application of colonoscopy. Endoscopy is helpful in relieving distention but may also be dangerous in the patient with a massively distended colon, particularly at the level of the thin-walled cecum. Colonoscopy also appears to be associated with a high rate of treatment failure and recurrence. Surgical decompression may take the form of cecostomy or may require exteriorization or resection of the colon if infarction has occurred. A series of 12 patients has been presented. The patients were all referred to a single surgeon in a university medical center over a 4 1/2 year period with clinical patterns not suggestive of a common cause but a similar clinical evolution of Ogilvie's syndrome. The prognosis for such patients in whom the complication is recognized early and in whom decompression is performed endoscopically or surgically is encouraging. If recognition is late and particularly if perforation and gangrene result, mortality is nearly 50 percent.

Three children with malrotation 4.5, 5 and 9 years old at operation are presented. Their preliminary diagnoses were gastrointestinal (GI) allergy, GI allergy with colon irritable and psychosomatic abdominal pain. They were treated on an outpatient basis under these diagnoses for more than two years before their malrotations were discovered. In two children radiology did not demonstrate any signs of intestinal obstruction and in one of these children repeated radiological examinations were necessary for the diagnosis of malrotation. Operative findings were chronic volvulus with compromised blood flow and obstructive duodenal bands. The third child suffered acute strangulation ileus with gangrene of the intestines before diagnosis was made. We conclude that special consideration must be given to the possibility of malrotation when treating and radiologically investigating children with GI disturbances.

A case of idiopathic or Fournier's gangrene of the scrotum is described with unusual extension to the perineum. The clinical features of this disease are summarized. The literature is reviewed for extra genital extension of this gangrene of unknown aetiology. Coincidental association between infections with Onchocerca volvulus and scrotal gangrene was observed.

Fifty-eight patients with acute caecal volvulus are presented. Fifty-five patients had plain abdominal radiographs taken shortly after admission and the diagnosis was suspected in 29 (53%). Forty-five of these radiographs have been reviewed and, in retrospect, the diagnosis could have been made in 40 (89%). The dilated caecum usually assumes a 'comma-shape', retains its haustral markings and may be located anywhere within the abdomen but is most frequently seen centrally or occupying the left upper quadrant. Diagnostic difficulties were found in patients with peritonitis and when there was gross small bowel dilatation. Accurate diagnosis is vital as delay in the surgical treatment of this condition may lead to an increased incidence of gangrene of the caecum and a higher mortality.

Thirty four neonates presented with acute duodenal obstruction due to malrotation during a 9 year period between 1973 and the end of 1981. Of these, 20 patients (58.8%) presented in the first week of life, and 24 (70.5%) had an associated midgut volvulus. This frequent association is stressed as bowel necrosis occurs very rapidly. Massive gangrene of small bowel was present in 5 patients, extensive resection was necessary in 3 patients, of whom 2 died postoperatively (5.8%). Five patients required reoperation and 10 had additional G.I. malformations (29.4%).

Cecal volvulus is a malrotational abnormality of the intestine that causes obstruction. Diagnosis is difficult and, if delayed, the results may be intestinal ischemia, perforation, sepsis, and even death. Cecal ischemia or gangrene cannot always be determined from physical and laboratory findings. Although not always conclusive, contrast radiography may be helpful; however, laparotomy is often required for definitive diagnosis and therapy. If vascular compromise of the cecum is found, right hemicolectomy is the treatment of choice. In the absence of ischemia, decompressive tube cecostomy, simple detorsion, and cecopexy have all been recommended, but the optimal treatment is a matter of controversy.

We retrospectively evaluated ten cases of cecal volvulus. The average age of these patients was 57 years. Five patients were more more than 60 years old and three were over 70. All patients had significant delays in coming to the hospital, and all had concomitant medical problems that made them poor operative risks. Our data and data in the recent literature support a conservative approach in debilitated patients with acute cecal volvulus. We do not recommend resection of the cecum if it is viable at the time of operation. Resection remains the treatment of choice when gangrene is present, but primary ileotransverse colostomy is contraindicated in this population of patients.

For a period of four years, five adult patients with nonrotation of the intestine and midgut volvulus have been treated. Two distinct clinical presentations were encountered. The chronic presentation is that of colicky abdominal pain, often present for many years, which is corrected by surgical intervention. The acute presentation with strangulation of the intestine may occur without pre-existing symptoms. Knowledge of this entity and a high index of suspicion are necessary for the diagnosis because massive gangrene of the intestine may result from a delay in treatment. Prophylactic surgical treatment in the asymptomatic patient is recommended to prevent this catastrophic occurrence.
