Three patients (aged 47–84 years) with bile duct stones underwent this approach during laparoscopiccholecystectomy at a tertiary center. Biliary cannulation and complete stone removal were successful in all cases, with no intraoperative or postoperative complications. The average hospital stay was 3 days. This technique appears feasible, although larger studies are needed to confirm its efficacy, safety, and potential cost-effectiveness.  \nKEYWORDS: ERCP; rendezvous; choledocholithiasis  \nABBREVIATIONS: ALP, alkaline phosphatase; ALT, alanine transaminase; AST, aspartate transaminase; CBD, common bile duct; CRP, Creactive protein; ERCP, endoscopic retrograde cholangiopancreatography; GGT, gamma glutamyltransferase; LC, laparoscopic cholecystectomy; MRCP, magnetic resonance cholangiopancreatography; PICC, peripherally inserted central catheter; WBC, white blood cells  \nINTRODUCTION  \nThe rendezvous technique has been previously used during cholecystectomy for the treatment ofcholedocholithiasisin the setting of cholecystitis, demonstrating success rates comparable to those of endoscopic retrograde cholangiopancreatography (ERCP) performed before surgery with less complications associated with the ERCP, such as canulation of the pancreatic duct and its complications, edema of the papilla, less use of precut, and less in hospital stay.1,2 This approach is particularly useful in patients with complex anatomy.3,4 Also, it has the potential of reducing costs to the patient with confirmed or high risk of choledocholithiasis because the problem can be solved in only one procedure, and in theory, reducing the risks associated with anesthesia.  \nIn the conventional rendezvous technique, a metallic guidewire is advanced through the cystic duct and out the ampulla. However, in some patients, the guidewire may fail to pass, or it maybe harder to manipulate by the surgical team and pass through the cystic duct during laparoscopy because of the size of the guidewire (usually 0.025 or 0.035 inches and 230-450 cm in length) . To overcome this limitation, we developed a modified approach in which a 5 Fr peripherally inserted central catheter (PICC) is used instead. This catheter was chosen because of its size (0.065 inches in diameter and 50–60 cm in length), flexibility, and ease of manipulation. The catheter is advanced through the cystic duct and ampulla with fluoroscopic guidance, followed by the introduction of a duodenoscope. A sphincterotome loaded with a guidewire is then passed through the working channel, aligned with the PICC, and the guidewire is advanced into the common bile duct (CBD) . Once the guidewire is securely in place, the PICC is withdrawn, and standard ERCP is performed, with sphincterotomy and balloon sweep to remove the stones. After the ERCP is completed, the cystic duct is clipped, and the laparoscopic cholecystectomy (LC) was completed (Figure 1) .  \nACG Case Rep J 2026;13:e01960 . doi:10 . 14309/crj.0000000000001960.
