Laparoscopic-Assisted Transgastric Endoscopic Retrograde Cholangiography (LTG-ERCP): An Option for Managing Choledocholithiasis in a Patient With Prior Bariatric Surgery at a Community Hospital.

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
Endoscopic retrograde cholangiography (ERCP) has become a mainstay in managing choledocholithiasis. Conventional endoscopic access to the ampulla of Vater becomes impossible after Roux-en-Y gastric bypass (RYGB) due to modified anatomy. In specialized centers with advanced gastrointestinal capabilities, techniques like double-balloon endoscopy can be utilized for biliary decompression. However, facilitating patient transfer to these centers can be difficult due to a common postoperative issue in a large population. Laparoscopic transgastric (LTG)-ERCP has been gaining popularity because of its high success rates and ability to carry it out in community healthcare settings. Here we present a case of choledocholithiasis in an RYGB patient successfully managed with LTG-ERCP at a community hospital. Our patient was a 51-year-old female with a history of sleeve gastrectomy with conversion to gastric bypass who presented to the emergency department for evaluation of severe epigastric pain and nausea. Laboratory testing was consistent with elevated bilirubin and alkaline phosphatase levels (1.5 mg/dl and 140 U/L, respectively). Abdominal ultrasound showed biliary sludge in the common bile duct (CBD). Subsequent magnetic resonance cholangiopancreatography (MRCP) showed dilatation of the CBD measuring up to 1 cm with multiple stones in the biliary system. After a multidisciplinary discussion between the GI and surgery teams, an LTG-ERCP along with cholecystectomy was performed, and CBD stones were successfully removed, resulting in the resolution of the patient's symptoms, and the patient was discharged home without any complications. LTG-ERCP is considered a safe and effective approach for managing biliary obstruction after RYGB. This procedure has the advantage of endoscopic biliary decompression and cholecystectomy being performed in a single setting.
