OGBN V02 Robotic common bile duct clearance

Abstract Background A 44-yar old male patient presented with painful obstructive jaundice and bilirubin of 127 μmol/L. A Contrast Enhanced Computed Tomography (CECT) revealed dilated biliary tree as a result of obstructing stone in the proximal common bile duct (CBD). The patient underwent an Endoscopic Retrograde CholangioPancreatography (ERCP) and sphincterotomy which demonstrated pus in the bile duct, but also a stone impacted in the common hepatic duct which could not be extracted endoscopically. Therefore, a 7Fr pigtail stent was inserted. Subsequently, he was discharged home and re-admitted for an elective robotic cholecystectomy and bile duct clearance 6 weeks later. Methods Robotic CBD clearance was performed using DaVinciXi system, a 12mm Airseal and four 8mm robotic ports. The patient was supine with split legs(15 degrees), in reverse Trendelenburg position and left tilt. The CBD was dissected out, the anterior duct wall was delineated and longitudinal choledochotomy was carried out. A large stone was extracted through the choledochotomy site followed by removal of stent. Subsequently, a cholangioscopy was performed using a single-use flexible ureteroscope and no further stone disease was identified proximally or distally. Following this, a bile duct closure was performed using 4-0 Polydioxanone interrupted sutures and SutureCut Needle Driver. Results There were no intra- or post-operative complications. The patient made an excellent recovery from robotic common bile duct clearance and was discharged home less than 24 hours post procedure. Conclusions This video presentation highlights the technical aspects of robotic common bile duct clearance and demonstrates that the robotic system allows for accurate dissection and precise suturing which could reduce the risk of bile duct stricture.
