Setting up a surgical complex gallstone service in a non-HPB unit

Abstract

Complex gallstone disease is associated with a higher risk of complication during laparoscopic cholecystectomy than biliary colic and simple cholecystitis. It is traditionally managed in a hepatopancreaticobiliary (HPB) unit where there is expertise for common bile duct exploration and repair. We developed a mentorship scheme for a busy upper gastro-intestinal (UGI) unit, with support from a specialist HPB unit to treat complex gallstone disease, to reduce the burden on the HPB unit and enable local treatment of patients. Through the creation of a service level agreement, the specialist HPB unit were commissioned to provide mentorship for two surgeons at a large UGI unit with an interest in providing a complex gallstone service to their local population. Eight sessions of mentored operating were supported, with the provision for additional support if complications occurred. There were 14 patients included in the mentorship phase of the programme from November 2015 to May 2017. Cholecystectomies were performed on patients with previously complex histories, which included: previous cholecystostomy; CBD stones and multiple ERCPs; suspected choledochoduodenal fistula; suspected cholecystoduodenal fistula; suspected Mirrizzi's syndrome; previous significant intra-abdominal operation; and significant medical co-morbidities. There was one post-operative complication requiring a return to theatre, and one minor wound infection associated with the complex gallstone lists. We demonstrated a method to reduce the burden on specialist HPB unit for the operative management of complex gallstone disease and safely implement such a service at large UGI unit with an interest in providing a complex gallstone service.
