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
backgroundEndoscopic retrograde cholangiopancreatography (ERCP) is technically challenging in patients with Roux-en‑Y gastric bypass or omega loop reconstruction due to altered gastrointestinal anatomy. At the same time, this patient population has an increased risk for the development of cholelithiasis and choledocholithiasis after bariatric surgery, frequently requiring interventional biliary treatment.
methodsThis retrospective single-center study analyzed patients who underwent laparoscopy-assisted transgastric ERCP (LA-ERCP) after bariatric surgery between October 2018 and April 2025. In this study six patients with prior Roux-en‑Y gastric bypass or omega loop reconstruction underwent a total of seven LA-ERCP procedures for choledocholithiasis. Clinical characteristics, procedural success, operation time and postoperative complications were evaluated.
resultsSuccessful papillotomy and complete bile duct stone clearance were achieved in all cases. Simultaneous laparoscopic cholecystectomy was performed in three procedures. No conversion to open surgery was required. The mean duration of surgery was 156 ± 29.6 min. Postoperative complications occurred in two cases and were managed conservatively or endoscopically. The median hospital stay was 5 days.
conclusionThe LA-ERCP procedure is a safe and effective treatment option for choledocholithiasis in patients after bariatric surgery. Although the procedure is more invasive than purely endoscopic alternatives, it offers high technical success rates and enables the use of standard ERCP equipment. The LA-ECRP procedure provides a decisive advantage, particularly when simultaneous cholecystectomy is indicated.
