[A Case of Hepatic Oligometastasis from Distal Bile Duct Cancer Treated with Laparoscopic Surgery Five Years after Pancreatoduodenectomy].

An 82-year-old male patient underwent pancreatoduodenectomy for pStage Ⅱ distal bile duct cancer. During observation, after 5 years, a solitary metastasis in segment 6 of the liver was detected, and laparoscopic partial hepatectomy was planned. The patient was successfully treated without complications, and the resection margins were negative. The patient survived without recurrence for 6 months after the surgery. Although no consensus has been reached regarding the surgical indications for liver metastases in patients with biliary tract cancer, recent reports have highlighted the merits of surgery. Factors, such as good health status, expected curative resection, number of tumors, tumor diameter, and duration after the first surgery were considered good candidates for surgery. Generally, Pringle's maneuver is difficult after pancreatoduodenectomy because of severe adhesions;however, some cases are considered possible for laparoscopic resection depending on the location, such as segments 2-6.
