ThP4.7 - The outcome of a single stage Laparoendoscopic rendezvous ERCP and laparoscopic cholecystectomy for cholecystocholedocholithiasis in a DGH

Abstract Cholecystocholedocholithiasis is managed surgically by laparoscopic cholecystectomy (LC) and simultaneous common bile duct (CBD) exploration or by preoperative Endoscopic Retrograde Cholangiopancreatography (ERCP) followed by LC. Rendezvous ERCP (RERCP) is an innovative laparoendoscopic technique combining LCs and ERCPs. As a single staged procedure, a LC is performed and selective canulisation of the CBD is aided by laparoscopic transcystic placement of a guide-wire into the duodenum. We present a case series of RERCPs within a DGH. This case series collected retrospective data (2014-2023) involving 33 patients, of which 21 underwent RERCP. Preoperative variables included age, indication, gender, ASA grade, Charlson comorbidity index (CCI), frailty score and indication. Postoperative variables analysed were operating time, complications, 30-day re-admission rates and length of stay in hospital (LOSH). Of the 21 patients who underwent a RERCP, 76% (n=16) were female. The average age was 60±17years and 59% (n=13) of all procedures were elective. The ASA range was I to III, average CCI and frailty score were 2.4±1.9 and 0.1±0.4 respectively. 52% (n=11) of patients had a previous failed ERCP. The average operating time was 152±39mins. The average LOSH was 3.5±2.8days and 2.5±2.1days following the RERCP. Biliary (including pancreatitis) and non-biliary complications were 9.5% (n=2) and 9.5% (n=2) respectively. The 30-day readmission rate was 9.5% (n=2). There was no significant difference in the operating time (p=0.16), LOSH (p=0.19) complication (p=0.13) and readmission rates (p=0.50) between emergencies and elective procedures. RERCP remains a valuable option when managing cholecystocholedocholithiasis in emergency and elective settings.
