[A case of postpancreaticoduodenectomy local recurrence successfully treated with extended resection].

A 68 -year-old man underwent a pancreaticoduodenectomy after being diagnosed with primary duodenal cancer. The postoperative pathological diagnosis was tub2, SE, ly1, v1, panc3, pn+, N0. Although adjuvant chemotherapy was administered, local recurrence in the portal region was detected 18 months later. The recurrent tumor pressed against the region of the bile duct anastomosis, which caused obstructive jaundice. After serum bilirubin levels were reduced, resection of the recurrent tumors was performed. This required resection of the transverse colon, parts of the portal vein, and the inferior vena cava. The bile duct anastomotic region, which had been infiltrated by the tumor, was excised and rebuilt. The postoperative pathological diagnosis was tub2. The patient continued to receive adjuvant chemotherapy and showed no signs of recurrence 9 months after surgery. Extended resection for local recurrences of primary duodenal cancer may be an effective means of disease control.
