Аннотация
A 60s man underwent upper gastrointestinal endoscopy at a regular medical check-up without symptoms, which showed an ulcerative region in the duodenal ampulla, measuring 3 cm in diameter. He was diagnosed with poorly differentiated adenocarcinoma on biopsy and referred to our hospital. Abdominal contrast-enhanced CT scan revealed an enhanced-ulcerative tumor, measuring 3 cm, at the duodenal ampulla. After the preoperative diagnosis of adenocarcinoma of the duodenal ampulla, subtotal stomach-preserving pancreatoduodenectomy with regional lymph node dissection was performed. The final diagnosis was neuroendocrine carcinoma(NEC)of the duodenal ampulla. He has been alive for 9 years with no recurrences. NEC of the duodenal ampulla is rare, and its prognosis is poor. We report a case of long-term survival after resection of NEC of the duodenal ampulla.
