Experience of endoscopic use of the combined method «Rendezvous» on the distal section of the common bile duct in residual choledocholithiasis with an external biliary fistula

The article presents a clinical observation of patient N., 74 years old, with a history of surgery in August 2023 for cholelithiasis. During the surgical intervention, a number of complications were noted that required repeated operations and drainage of the common bile duct. In the postoperative period, drainage migrated with a clinical picture of biliary peritonitis. Relaparotomy, choledocholithotomy, lithoextraction, and redrainage of the common bile duct according to Kehr were performed. Due to the dislocation of the Kehr drainage, a drainage was installed in the subhepatic space, through which persistent external bile leakage was maintained. The patient underwent multi-stage endoscopic surgical treatment, as a result of which the passage of bile into the duodenum was restored. The external biliary fistula closed. The patient’s quality of life improved.
