Diagnostics of Inflammatory Bowel Disease

Complications of fiberoptic endoscopy

Forty-five polyps were encountered at duodenoscopy between 1973 and 1978. Upper gastrointestinal x-rays were helpful in 25 patients, 13 of whom had duodenal polyps and 12 duodenal deformity or mass lesions. Polyps in 23 patients were larger than 1 cm in size. Biopsies were done in 38 patients; in 19 there was only normal duodenal mucosa or chronic inflammation. Eight adenomatous polyps, six villous adenomas, two Brunner's gland hyperplasia, two lipomas, and one carcinoid tumor were found. Surgery was performed in eight patients and endoscopic polypectomy in four. We conclude that 1) small duodenal polyps are frequently missed on upper gastrointestinal x-rays, but these are submucosal polyps of little significance; 2) in general, polyps cannot be differentiated endoscopically into tissue categories, but villous adenomas show some characteristic features which allow a dependable endoscopic diagnosis; 3) a villous adenoma warrants excision because of the high incidence of malignancy; and 4) pedunculated duodenal polyps can be removed safely with endoscopic snare excision.

Duodenal polyps: diagnosis and management.

The mortality for liver abscesses has been inordinately high. The over-all mortality for pyogenic abscesses has been approximately 75% in the past. 1,2 Granted that liver abscesses frequently are actually only one lifeendangering manifestation of an infection or disease of even greater magnitude elsewhere in the body and granted that liver abscesses are not a common problem, improvement in mortality and morbidity should be achieved. The most important reason for the high mortality appears to have been the late recognition or actual failure of recognition of the presence of a liver abscess requiring surgical drainage. 2 Inadequate surgical drainage procedures and failure to utilize exhaustive bacteriologic techniques to identify the infecting organism, especially fastidious anaerobic bacteria, are other important reasons for the persistent high mortality of this disease. Our recent experience indicates that this high mortality of liver abscesses can be reduced by utilization of certain techniques introduced in the

Pancreatic carcinoma in a patient with cystic fibrosis

We reviewed colorectal biopsies and clinical records from 36 patients with chronic watery diarrhea who had been diagnosed as having microscopic colitis and compared their histologic features with the more detailed and precise criteria for lymphocytic colitis. Published pathologic criteria for lymphocytic colitis were applied to the biopsies and compared. Focal or diffuse nature of the lymphoid infiltrate were noted separately. The focal lymphoid infiltrate was related to lymphoid aggregates in the lamina propria of the mucosa. Eighteen cases had focal lymphoid cell infiltration, and 16 of them had associated diverticula, polyps, or both. Eighteen cases had diffuse lymphoid cell infiltration, and six of them had diverticula or polyps. Results indicate that focal cellular infiltration strongly predicts associated diverticula or polyps. The group with no diverticula or polyps most closely conformed to histologic criteria for lymphocytic colitis (Kruskal-Wallis P < 0.02). We conclude that lymphocytic colitis comprises a well-defined group of cases within the large and less-defined group of microscopic colitis.
