The cut end of the short duct that joined the gallbladder to the main bile duct, examined by the pathologist after a gallbladder is removed. If cancer cells reach this edge, part of the main bile duct usually has to be removed at a second operation; if it is clear, the bile duct can be left alone.
Answer a few questions from a report and read the guideline statement that applies, quoted word for word with its source. Educational aids to prepare for an appointment, not advice.
The cystic duct margin is the resection margin closest to the extrahepatic bile duct in every cholecystectomy specimen. The AHPBA consensus asks pathologists in high-incidence areas to examine it in every routine specimen alongside at least three sections of wall, and, at re-resection for gallbladder cancer, to resect the bile duct only when needed to achieve a negative (R0) margin, in practice when the cystic duct margin is positive (Aloia 2015; Soreide 2019). Frozen section of the bile duct margin during surgery is used to decide the extent of resection and generally agrees with the final result (Yamaguchi 2005). A positive margin, or dysplasia running into the duct, is also how a cystic duct carcinoma may first be suspected (Kim 2025). Margin status is listed among the pathological findings on the gallbladder cancer page because it changes the operation.
Most pancreatic cancers arise in the head next to the bile duct, which is why jaundice is the presenting sign; bile duct cancers are named by where along the tree they sit.
