Function-Preserving Laparoscopic Local Resection of Duodenal Papillary Adenomas.

Duodenal papillary adenomas, although rare, have significant potential for malignant transformation, necessitating precise intervention. Current surgical options for treating duodenal papillary adenomas include pancreaticoduodenectomy, endoscopic resection, and function-preserving laparoscopic resection. Although traditional pancreaticoduodenectomy has undergone substantial advancements in recent decades, it still carries a high risk of perioperative complications and mortality, making it a less preferred choice. Endoscopic resection is suitable for smaller tumors; however, it presents limitations when applied to larger tumors, potentially resulting in serious complications such as bleeding and perforation. In contrast, function-preserving laparoscopic resection of duodenal papillary tumors reduces the need for extensive organ resection or digestive tract reconstruction, thereby lowering surgical risks and better preserving digestive function. By combining preoperative placement of pancreatic duct and biliary stents with function-preserving laparoscopic resection, duodenal papillary adenomas not amenable to endoscopic removal were successfully resected without significant perioperative complications. The main procedures included preoperative placement of pancreatic duct and biliary stents; intraoperative mobilization of the descending duodenum through Kocherization; longitudinal incision of the anterolateral duodenal wall; incision along tumor margins to expose mucosal and submucosal layers; complete tumor resection along its base; and repair and reconstruction of the duodenal papilla and wall. Postoperative follow-up indicated good recovery and patient satisfaction. These findings suggest that function-preserving laparoscopic resection is a safe and feasible option for selected duodenal papillary adenomas.
