Function-Preserving Laparoscopic Local Resection of Duodenal Papillary Adenomas

Area of Science:

• Gastroenterology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Duodenal papillary adenomas are rare but carry a risk of malignant transformation.
• Traditional treatments like pancreaticoduodenectomy have high complication rates, while endoscopic resection is limited for larger tumors.

Purpose of the Study:

• To evaluate the safety and feasibility of function-preserving laparoscopic resection for duodenal papillary adenomas.
• To assess outcomes in patients with adenomas not suitable for endoscopic removal.

Main Methods:

• Preoperative placement of pancreatic duct and biliary stents.
• Function-preserving laparoscopic resection involving duodenal mobilization, tumor resection, and reconstruction.
• Detailed description of surgical steps including Kocherization and duodenal wall incision.

Main Results:

• Successful resection of duodenal papillary adenomas not amenable to endoscopic removal.
• No significant perioperative complications were observed.
• Patients showed good postoperative recovery and high satisfaction.

Conclusions:

• Function-preserving laparoscopic resection is a safe and feasible surgical option for selected duodenal papillary adenomas.
• This technique reduces surgical risks and preserves digestive function compared to traditional methods.
