Ampullary Carcinoma

This prospective, multicenter, randomized controlled trial aims to evaluate the effectiveness of negative-pressure duodenal drainage compared with prophylactic pancreatic duct stenting in preventing post-endoscopic papillectomy (EP) pancreatitis. Eligible patients undergoing EP will be randomized 1:1 to receive either negative-pressure drainage or pancreatic duct stenting. The primary outcome is the incidence of post-EP pancreatitis. Secondary outcomes include other procedure-related complications, procedure time, technical success, length of hospital stay, hospitalization cost, en-bloc and R0 resection rates, and postoperative hyperamylasemia.

This is a monocentric, prospective, randomized controlled trial comparing the safety and efficacy of laparoscopic pancreaticoduodenectomy (LPD) versus open pancreaticoduodenectomy (OPD). The study aims to determine the morbimortality of the laparoscopic approach compared to the gold standard open approach in adult patients with pancreatic or periampullary lesions.

A Phase Ⅱ, single-arm study to assess the safety, tolerability, and efficacy of Surufatinib Combination With Toripalimab in Patients With recurrent or metastatic ampulla tumors.
