Colonoscopic assessment of radiologic strictures of the colon.

The authors studied 47 patients with radiologic evidence of stricture to determine whether colonoscopy in this situation increased the accuracy of diagnosis and how this procedure might influence patient management. Colonoscopy increased to 81% the diagnostic accuracy, which was established at 38% with the single-contrast enema. Failure of both techniques to establish a precise diagnosis was 19%. From the clinical and radiologic data, surgical exploration for the 47 strictures would have been necessary in 28, not indicated in 9, and indicated solely for diagnostic purposes in 10. The addition of colonoscopy prevented unnecessary laparotomy in 5 (18%) of the first group and in 8 (80%) of the last. The authors conclude that colonoscopy should be complementary to the standard radiologic examination for colonic strictures, especially when carcinoma is suspected or if roentgenography does not provide a definitive diagnosis.

Acute colonic pseudo-obstruction or Ogilvie's syndrome. Report of two cases treated with colonoscopic decompression and review of the literature.

Acute colonic pseudo-obstruction (ACP), or Ogilvie's syndrome, is a disorder characterized by massive dilatation of the colon, and typically occurs in the critically ill or post-operative patient. The clinical presentation may be impossible to distinguish from mechanical causes of colonic obstruction. Its importance is reflected in an overall mortality of up to 30%, perforation of the cecum occurring in 14.8% of patients with a reported mortality of up to 46%. Medical therapy has had variable results. Tube cecostomy or other operative interventions can lead to much morbidity and mortality in the critically ill patient. Colonoscopy recently has proven to be highly effective in achieving colonic decompression as well as excluding a mechanical etiology for obstruction and poses minimal risk to the patient. Colonoscopy should be reserved for patients who show progressive cecal dilatation or who deteriorate clinically despite aggressive medical therapy. We report two patients with ACP treated with colonoscopy and review the literature.

Successful management of post-cesarean-section acute pseudoobstruction of the colon (Ogilvie's syndrome) with colonoscopic decompression. A case report.

Although acute pseudoobstruction of the colon is a rare entity, a large percentage of the reported cases have occurred following obstetric and gynecologic surgical procedures. Early recognition is mandatory to avoid severe and potentially fatal complications and can allow successful decompression by means of colonoscopy, thus avoiding surgical intervention, as in the case reported on here.

[Early colonic carcinoma--colonoscopic study].

Total colonoscopy has been carried out 4708 times in 3940 outpatients for recent four years and one month. 199 colonic carcinomas (72 focal, 46 invasive and 81 advanced carcinomas) have been detected and 120 of them were removed endoscopically. They contained of 8 early carcinomas in spite of the diminutive groups lesser than 5 mm in diameter. Colonic carcinomas were found out more frequently in the rectum and sigmoid colon (148 lesions, 74.4%), but not a few in the right sided colon (26 lesions, 13.1%). Therefore, the importance of total colonoscopy and endoscopic polypectomy should be emphasized to diagnose and treat malignant potentials.

Colonoscopic findings in patients with hemorrhoids, rectal bleeding and normal rectoscopy.

Within a period of 18 months, 387 patients were referred to the Proctologic Service at the Chaim Sheba Medical Center because of recurrent rectal bleeding. Hemorrhoids were found in 194 of these patients and further investigation showed that 45 of the 194 patients (23.2%) had other coexisting colonic pathology (12 cancers, 28 polyps, 4 inflammatory bowel diseases and 1 angiodysplasia). Sixteen of 40 patients with diverticulosis and 13 of 30 patients with hemoglobin less than 11 g/dl had additional colonic pathology. Single-contrast barium enema, which was used in this survey for screening of the colon, proved to be inaccurate. In view of the issue of cost-effectiveness, this study suggests that patients with recurrent rectal bleeding and hemorrhoids (Grades II and III) who had normal rectoscopy should be further investigated by double-contrast barium enema if they are greater than 40 years of age. All patients with anemia, diverticulosis or abnormal findings in barium enema should undergo total colonoscopy.
