[A Case of Successful Surgical Treatment for Paraaortic Lymph Nodes Recurrence of Gallbladder Cancer].

Cholecystectomy with gallbladder bed resection and regional lymphadenectomy was performed in a 75-year-old man with advanced gallbladder cancer. Pathological examination revealed adenocarcinoma in the gallbladder with regional lymph node metastases. Cancer recurrence was found in paraaortic lymph nodes behind the duodenum 9 months after the surgery. Although chemotherapy using S-1 was initiated, the lymph nodes remained the same size after 2 courses without any new recurrent regions. Lymphadenectomy was then performed as a curative surgery. The patient has remained alive without recurrence for 46 months after the second surgery.
