such patients who underwent pancreatectomy for carcinoma developing in the pancreatic remnant after pylorus-preserving pancreatoduodenectomy (PpPD) for invasive pancreatic ductal carcinoma. One patient underwent PpPD for invasive pancreatic ductal carcinoma and received adjuvant chemotherapy. Follow-up computed tomography (CT) demonstrated a low-density mass in the remnant pancreas, which was diagnosed as a carcinoma by endoscopic ultrasound-guided fine-needle aspiration cytology 5 years 10 months after PpPD. She underwent curative resection of the remnant pancreas and is alive and well 13 months after the second operation. The other patient underwent PpPD for invasive pancreatic ductal carcinoma. Follow-up CT showed a low-density mass in the remnant pancreas after 2 years 11 months. He received systemic chemotherapy with S-1 for 3 months. The tumor shrank, and the patient underwent curative resection of the remnant pancreas 3 years 1 month after the initial operation. Repeated pancreatectomy may provide a chance of long survival for patients with carcinoma developing in the remnant pancreas after pancreatectomy if the recurrence occurring at long term is limited to the remnant pancreas.
