Biliopancreatic limb obstruction secondary to 9 cm gallstone nearly two decades following open Roux-en-Y gastric bypass and cholecystectomy: a rare and challenging case.
Article in Journal of surgical case reports, 2025. 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
Gallstone ileus is a rare complication of chronic cholelithiasis and an exceedingly uncommon cause of bowel obstruction following Roux-en-Y gastric bypass (RYGB), particularly after cholecystectomy. We report the first known case of a large gallstone causing obstruction of the biliopancreatic limb in an 80-year-old woman with prior RYGB, cholecystectomy, and choledochoduodenostomy. She underwent successful open enterolithotomy with stone extraction. This case highlights the diagnostic and technical challenges posed by altered post-RYGB anatomy and emphasizes the importance of maintaining a high index of suspicion in similar presentations. Early recognition and individualized operative management are critical to achieving favorable outcomes in this rare but potentially life-threatening condition.
