[Surgical treatment for gall bladder cancer with a confluence stone-a case report].

: The patient was a 71-year-old man. In September 2011, he experienced abdominal pain with high fever. Abdominal computed tomography (CT) diagnosed acute cholecystitis with a confluence stone (corlette classification type II). He underwent total cholecystectomy and placement of a T-tube in the main bile duct through the gall bladder duct. However, pathological investigations revealed gall bladder cancer in the neck and body part of the gall bladder, leading to a diagnosis of gall bladder adenocarcinoma(Gbn, Flat type, tub2, INF β,pSS, pHinf0, pBinf1, pPV0, pA0, pT3) with a confluence stone. We suspected that the tumor was present in the common bile duct. Therefore, in October 2011, he underwent choledochectomy, resection of the liver bed, lymph node dissection, and choledocho-jejunostomy. Pathological findings revealed that the tumor was present in the common bile duct. He died 8 months after the last surgery because of recurrence of peritoneal metastasis.
