Sigmoid colon perforation presumed to be stercoral in origin in an elderly patient with chronic constipation: 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
Stercoral perforation (SP) is an uncommon but potentially life-threatening complication of chronic constipation that predominantly affects elderly individuals. Early diagnosis is challenging because of nonspecific clinical manifestations and the risk of rapid progression to feculent peritonitis and sepsis. We report the case of an 85-year-old woman who presented with severe acute lower abdominal pain, abdominal distension, nausea, vomiting, and absence of flatus or bowel movements. She had a 6-month history of chronic constipation and long-term antihypertensive therapy with levamlodipine besylate. Computed tomography (CT) demonstrated free intraperitoneal air, abdominal fluid, and fecal impaction within the sigmoid colon. Emergency laparoscopic exploration followed by limited open surgery revealed severe feculent peritonitis and a 2.5 cm × 2.0 cm perforation of the distal sigmoid colon. Necrotic tissue at the perforation margin was debrided, and the perforated sigmoid segment was exteriorized and matured as a colostomy. No bowel resection was performed because diffuse ischemia or necrosis was not identified intraoperatively and the patient was considered high risk because of advanced age and poor baseline condition. The diagnosis of probable stercoral perforation was based on the clinical presentation, radiological findings, and intraoperative observations. Postoperatively, the patient required intensive care monitoring and received broad-spectrum antimicrobial therapy, nutritional support, and electrolyte replacement. She was discharged in stable condition on postoperative day 14. At the 11-week follow-up, she tolerated a regular diet and reported regular bowel movements. At 1-year follow-up, she remained independent in daily activities, with no recurrent perforation, severe constipation, or rehospitalization. This case highlights the importance of early CT evaluation, individualized surgical decision-making, prompt source control, and comprehensive perioperative management in elderly patients with suspected stercoral perforation.
