title: Laparoscopic transduodenal local resection of periampullary neuroendocrine tumor: a case report.
abstract: Studies on laparoscopic transduodenal local resection have not been readily available. Only three cases have been reported in the English-language literature. We describe herein a case of 25-year-old woman with periampullary neuroendocrine tumor (NET). Endoscopic ultrasonography revealed a duodenal papilla mass originated from the submucosa and close to the ampulla. The periampullary tumor was successfully managed with laparoscopic transduodenal local resection without any procedure-related complications. Pathological examination showed a NET (Grade 2) with negative margin. The patient was followed up for six months without signs of recurrence. This case suggests that laparoscopic transduodenal local resection is a feasible procedure in selected patients with periampullary tumor.
