IntroductionNorthwest Ontario has a high prevalence of cholelithiasis, at 1.6 times the provincial norm. There is a concomitant 14% rate of choledocholithiasis. Accessing surgical services in the region often requires extensive travel by air. Choledocholithiasis management is typically with a 2-staged approach, an endoscopic retrograde cholangiopancreatography (ERCP) followed several days or weeks later by laparoscopic cholecystectomy (LC). Regional surgeons were concerned about the patient burden of travel and the loss to follow-up inherent in scheduling two independent procedures at separate hospital admissions. They adopted a 1-stage management, called the rendezvous procedure, which describes the simultaneous performance of an ERCP and LC.MethodsWe accessed Sioux Lookout Meno Ya Win Health Centre hospital data for all patients receiving an ERCP and LC between 1 June 2019 and 1 December 2022. We documented patient demographics, operative outcomes, length of stay and transfer to other facilities.ResultsThere were 29 rendezvous procedures performed, with successful cannulation of the ampulla of Vater in 27 (93%) cases and stone removal in 23 (79%), with a complication rate of 7%. The operating time averaged 136 min, and two patients required transfer to a tertiary care centre and four were stented locally and required a return trip to Sioux Lookout for repeat ERCP and successful stone removal. The average length of stay was 2.1 ± 1.3 days. Patients who could not access a rendezvous procedure averaged 46.1 ± 78.1 days between procedures.ConclusionManaging choledocholithiasis with a 1-stage approach was safe and effective and reduced patient travel, time to definitive care and hospital admissions.
