Treatment

Incidental tumours diagnosed after a laparoscopic cholecystectomy need no further action unless the gall bladder was ruptured, in which case the trocar sites should be excised because abdominal wall metastases may occur. Tumours of more advanced stages should be treated with radical surgery (resection of segments 4 and 5, bile duct, and lymphadenectomy). Post-operative chemotherapy with cisplatin is of no proven benefit. Radiotherapy is used in cases of incomplete resection. For unresectable tumours, surgical or radiological biliary drainage is performed according to the same principles as for the palliative treatment of cholangiocarcinoma.
