Acute abdomen was the presenting manifestation of pseudomembranous colitis in six men who had previously been treated with antibiotics and presented with abdominal distention, pain, fever, and leukocytosis with absent or mild diarrhea. Plain abdominal radiographs revealed megacolon in two, combined small and large bowel dilation in three, with one of them showing volvuluslike pattern, and isolated small bowel ileus in one. Emergency colonoscopy was performed successfully in all patients and revealed pseudomembranes in five and nonspecific colitis in one. All patients had positive latex test results for Clostridium difficile, and two tested positive for cytotoxicity. All patients were treated with IV metronidazole, resulting in resolution of symptoms and abdominal findings. In addition, two patients underwent colonoscopic decompression with improvement. Endoscopically, complete resolution of the pseudomembranes occurred at 4 weeks in all cases. No patient had a recurrence. It is concluded that (a) pseudomembranous colitis may present as abdominal distention mimicking small bowel ileus. Ogilvie's syndrome, volvulus, or ischemia; (b) in such cases, emergency colonoscopy is safe and useful for diagnosis and therapeutic decompression and may obviate the need for surgery; and (c) treatment with IV metronidazole is effective. Colitis due to C. difficile should be considered in the differential diagnosis of acute abdomen in patients previously treated with antibiotics.

There are three main groups of indications of lower digestive tract endoscopy: (1) endoscopy may be performed to detect adenomatous polyps and thus prevent colorectal cancer by systematic excision of these polyps before they become invasive malignancies; (2) it may also be performed in patients whose symptoms (e.g. pain, diarrhoea or anaemia) may be due to a lesion of the colon. It usually provides evidence of such diseases as colorectal adenocarcinoma, ulcerative colitis, Crohn's disease, pseudomembranous colitis, post-irradiation colitis, collagen colitis, ischaemic colitis or colonic angiodysplasia; (3) finally, emergency endoscopy can be used in case of rectal haemorrhage, where it is often completed by haemostasis, or in case of volvulus, where it removes the occlusion.

Indications for colonoscopy in the intensive care unit include acute lower intestinal bleeding, sigmoid volvulus, pseudo-obstruction of the colon, and suspicion of pseudomembranous colitis. Although the incidence of cardiorespiratory complications may be higher in these critically ill patients, the procedure can be done safely with proper attention to detail. Because of colonic dilatation, endoscopy can often be done without bowel preparation.

Sixty-eight cases of transverse colon volvulus have been reported in the literature. The authors report the first case of transverse colon volvulus in association with Clostridium difficile pseudomembranous colitis, with a review of the available literature. It is possible that the acute inflammation of the colonic mucosa, which occurred from the pseudomembranous colitis in this patient, contributed to the development of volvulus. Further studies are needed to explore the role of mucosal inflammation in the occurrence of volvulus.

This article reviews a variety of specific colonic disorders that may have been an acute clinical presentation. Less common causes of colonic obstruction include volvulus, intussusception, and hernias. Nonobstructive colonic dilatation is most often due to pseudo-obstructions and toxic megacolon. Several miscellaneous disorders discussed include colonic perforation, complications of leukemia that may affect the colon, and pseudomembranous colitis. The pathogenesis and clinical aspects of these disorders are reviewed, but the radiologic features are emphasized.

A staging classification is proposed by CT findings in 27 patients with acute abdomen, caused by inflammatory colonic non-parasitic pathology. Of the 17 patients with diverticular disease, 4 were stage A (edema/ischemia on thickness of the abdominal wall), 2 were stage B (partial intramural infarction on the abdominal wall) and 3 were stage C (abscess/peritonitis and obstruction/vascular strangulation). None of the patients in the series were stage D (ischemia/infarction of the colonic wall with dilatation). Of the 4 patients with ulcerative colitis, 3 were stage A and 1 in stage C. Of the 3 patients with Crohn's disease, 2 were stage A and 1 was in stage C. Classified as stage D were 1 pseudomembranous colitis, 1 volvulus and 1 idiopathic megacolon. Clinical severity was in parallel with CT stages that gave better information on the progression of the pathology. Staging by CT in acute abdomen caused by inflammatory colonic non-parasitic pathology could be useful in therapeutics.
