[A case of two re-resections for peritoneal recurrence of pancreatic cancer].

A 63-year-old man underwent subtotal stomach-preserving pancreaticoduodenectomy and intraoperative radiation therapy for pancreatic head cancer (Stage IVa, JPS). Subsequently, he received adjuvant chemotherapy including gemcitabine (GEM). A peritoneal recurrence appeared adjacent to the right colon and the lower pole of the right kidney. He received chemotherapy including S-1 and GEM+S-1. Since the recurrent lesions were localized, he underwent resection for the recurrence lesions 2 years and 9 months after surgery. The resection was R1, and re-recurrence appeared in the lower pole of the right kidney. After chemotherapy and chemoradiotherapy, he underwent re-resection for the recurrence 4 years and 3 months after the first surgery. Three months after re-resection, multiple liver metastases appeared in the bilateral lobes. Reoperation can be one of the multidisciplinary management options for local recurrence of pancreatic cancer under specific conditions.
