Laparoendoscopic Rendezvous: An Effective and Safe Approach in the Management of Cholecysto-Choledocholithiasis in Selected Patients

Background: Different techniques have been proposed to manage Cholecysto-choledocholithiasis (CCL) advantageously in one stage. Among these, Laparoendoscopic Rendezvous (LERV) addresses the CCL issue with a laparoscopic cholecystectomy, with insertion of a guide wire into the common bile duct through an incision of the cystic duct, followed by the clearance of the bile duct carried out by the endoscopists. The aim of this study was to evaluate the safety and the efficacy of the one-stage vs. a two-stage approach (pre-operative ERCP followed by cholecystectomy), and to compare our results with data from the current literature. Methods: All patients that underwent LERV in our facilities between January 2018 and December 2023 were evaluated. As a control group, we included patients that underwent a two-stage technique called the “sequential approach”. The primary outcome was to evaluate the efficacy in obtaining complete clearance of the common bile duct (CBD). The secondary outcomes included morbidity, mortality, operative time, conversion rate, hospital stay and CDB stone recurrence. Results: 120 patients in the LERV group were included; meanwhile, 70 patients underwent pre-operative ERCP plus cholecystectomy. A 97% bile duct clearance success rate in the LERV group and 93% in the ERCP group was observed, respectively. The median intraoperative time for the one-stage technique was 122 min (p < 0.001) and the median hospital stay was 4 days (p < 0.001). In the LERV group, an overall morbidity of 15% was reported (18/120): 15 Clavien–Dindo type 1, one type 3a and two type 3b (p < 0.001). At a median follow-up of 14 months, five patients experienced stone recurrence. In the ERCP group, we had a 93% success rate; meanwhile, we had longer hospitalization (p < 0.001), 27% post-ERCP pancreatitis (p < 0.001) and a cumulative morbidity of 30%. Conclusions: LERV offers the advantages of a being single-stage procedure and shorter hospitalization, with a lower risk of clinically relevant post-ERCP pancreatitis and failed CBD cannulation.
