Management of concomitant cholecystoduodenal and cholecystocolonic fistulas with sigmoid colonic gallstone: a case report.
Article in Journal of surgical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Cholecystoduodenal fistula and cholecystocolonic fistula are rare complications of gallstone pathology. A 62-year-old female presented to our surgical assessment unit with abdominal pain and vomiting. A computed tomographic scan revealed complex biliary-enteric fistulas. The fistulas involved the gallbladder, duodenum, and colon, with evidence of partial gastric outlet obstruction secondary to a gallstone in the proximal duodenum. Furthermore, imaging revealed a large gallstone impacted proximal to the diverticular stricture in the sigmoid colon. A minimally invasive approach to resolve the fistula was unsuccessful; endoscopic retrograde cholangiopancreatography and sigmoidoscopy to dislodge the gallstones failed. This led to a laparotomy with jejunal enterotomy for stone removal and a Hartmann's procedure to address the impacted gallstone and the sigmoid diverticular stricture. Furthermore, the repair of both fistulae was performed during the index operation at the second operation, while dealing with unexpected colostomy necrosis.
