These injuries involve transection of the upper pa of the CBD and excision of a variable poion of the CBD proximal to first transection, including cystic duct-common duct junction. The stewa-way classification of laparoscopic bile duct injury Class Criteria I. CBD mistaken for cystic duct but recognized, cholangiogram incision of cystic duct extended into CBD II. Lateral damage to common hepatic duct from cautery or clips placed on duct, associated bleeding, poor visibility. III. CBD mistaken for cystic duct, not recognized on; CBD, CHD, RHD, LHD transected or resected IV. RHD mistaken for cystic duct, RHA mistaken for cystic aery, RHD and RHA transected; lateral damage to the RHD from cautery or clips placed on ducts.
