407 Robotic Assisted Cholecystectomy and Common Bile Duct Exploration for Single Stage Management of Complex Gallstone Disease

Abstract

Abstract Aim Laparoscopic cholecystectomy and common bile duct exploration (LC-CBDE) is an alternative to endoscopic retrograde cholangiopancreatography (ERCP) for treatment of choledocholithiasis. The ‘Achilles heel’ of LC-CBDE is the choledochotomy incision and closure following duct clearance. Robotic assisted surgery (RAS) aspires to overcome these technical challenges by providing improved views (3D enhancement) and articulated instruments potentially improving surgical precision. We aim to scrutinise the outcomes of an early series of robotic assisted cholecystectomy and common bile duct exploration (RC-CBDE) cases performed at our institution. Method Retrospective analysis from a specialist benign pancreatico-biliary unit in the United Kingdom was undertaken from April 2022 – December 2022 inclusive. All patients who underwent RC-CBDE for complicated gallstone disease were included. Collated data included patient demographics, perioperative investigations, intraoperative approach, and postoperative outcomes. Results 10 patients were identified. Median (IQR) age was 51 (33 – 66) years. Median (IQR) BMI was 26 (21 – 32) kg/m2. Median (IQR) Charlson Co-morbidity Index (CCI) was 1 (0 – 4). 4 patients were operated on during the acute presentation, with median (IQR) bilirubin 51 (34 – 252.5). Median (IQR) operative time was 176 (124 – 222) minutes. Median (IQR) post-operative length of stay was 4 (1 – 5) days. One patient required reintervention for port site hernia repair from drain site. Conclusions RC-CBDE is a safe and effective treatment for choledocholithiasis with equivocal outcomes to LC-CBDE. Benefits of RAS include enhanced views and ergonomics aiding precise closure of choledochotomy, which may both reduce complications and promote wider uptake of common bile duct exploration – a previously underutilised, technically-challenging operative procedure.
