A case of colonic perforation in collagenous colitis without diarrheal symptoms.: A case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionCollagenous colitis is an inflammatory disease characterized by hyperplasia of the collagen band beneath the colonic mucous membrane. Chronic diarrhea is a characteristic clinical symptom. The disease is often diagnosed accidentally on colonoscopy for chronic diarrhea, and patients without chronic diarrhea have few chances to suspect the disease. PRESENTATION OF CASE: The patient was a 75-year-old woman. The chief complaint was sudden upper abdominal pain and vomiting. There were no important findings regarding the consumed food or bowel habits (no diarrhea). Computed tomography revealed wall thickness and a small amount of free air around the descending colon. An emergency laparotomy was performed with the diagnosis of spontaneous colonic perforation. Intra-operative findings revealed a longitudinal ulcer and micro-perforation to the mesenterial side at the descending colon. Pathological findings revealed subepithelial collagenous band in the submucosal background of the ulcer, and which was diagnosed as collagenous colitis. DISCUSSION: Intestinal perforation in collagenous colitis is extremely rare. It was considered that perforation was caused by a transient increase in intestinal pressure in the background of collagenous colitis. Further, to the best of our knowledge, this is the first report of a critical case which presented without the characteristic symptom of chronic diarrhea.
conclusionWe report a rare case of colonic perforation of the collagenous colitis.
