Thinking Your Way Through a Difficult Laparoscopic Cholecystectomy: Technique for High-Quality Subtotal...

Laparoscopic subtotal cholecystectomy (LSC) is a bailout strategy to prevent bile duct injury in difficult gallbladder cases. It is associated with acceptable morbidity that is readily managed with postoperative interventions. Here we share our techniques for LSC. We begin with landmarking, which includes the line of safety, a theoretical line the sulcus of Rouvière and the junction of the cystic and hilar plates. If the fundus can be grasped, then the gallbladder is dissected off the cystic plate using the top-around approach. The gallbladder is then amputated, creating a short cuff of proximal gallbladder. This cuff can be left patent (2A) or cinched close with an ENDOLOOP (Ethicon) if it is small, ideally less than 1 cm (1A). If the fundus cannot be grasped, then an inverted T incision is made on the anterior gallbladder wall. The longitudinal incision is extended toward the fundus, and the transverse incision is extended superiorly along the cystic plate edge. Two "bunny ears" are developed and ultimately resected to excise the anterior gallbladder wall at an oblique angle while leaving the posterior wall intact (2B). If the remaining cuff is small, then it can be sutured closed against the gallbladder back wall (1B). In the setting of extensive bowel adhesion to the anterior gallbladder, we perform a fundectomy, from which we extend two incisions along the cystic plate to open the gallbladder like a clamshell. Our paper describes and illustrates our St Joseph's Health Centre institutional LSC approach and subtype classification (1A, 1B, 2A, and 2B).
