Modified Single-Incision Plus One-Port Versus Conventional Five-Port Laparoscopic Pancreaticoduodenectomy for Nonpancreatic Periampullary Adenocarcinomas
2 augusti 2026 uppdaterad av: Nanfang Hospital, Southern Medical University
Modified "Single-Incision Plus One "Versus Conventional "Five-Port" Laparoscopic Pancreaticoduodenectomy for Nonpancreatic Periampullary Adenocarcinomas: Study Protocol for A Multicentre Randomised Controlled Trial
This multicenter, randomized, controlled, non-inferiority trial will compare modified single-incision plus one-port laparoscopic pancreaticoduodenectomy (mSILPD+1) with conventional five-port laparoscopic pancreaticoduodenectomy (CLPD) in adults with histologically confirmed or highly suspected non-pancreatic periampullary carcinoma who are candidates for pancreaticoduodenectomy.
A total of 232 participants will be randomly assigned in a 1:1 ratio.
Outcome assessors who adjudicate complications and interpret imaging will be masked to treatment assignment.
The primary outcomes are all-cause mortality within 90 days after surgery and overall survival at 1 year after surgery.
Secondary outcomes will assess postoperative complications, surgical performance, postoperative recovery, disease-free survival, quality of life, and health-care costs.

Experimentell: Modified Single-Incision Plus One-Port Laparoscopic Pancreaticoduodenectomy
|
A pancreaticoduodenectomy performed through a 60- to 80-mm periumbilical single-incision access platform containing three trocars, with one additional 12-mm laparoscopic port.
Resection and reconstruction are performed according to the standardized multicenter operative protocol.

Aktiv komparator: Conventional Five-Port Laparoscopic Pancreaticoduodenectomy
Patients undergo conventional five-port laparoscopic pancreaticoduodenectomy.
Standard laparoscopic technique with five abdominal trocars is adopted for pancreaticoduodenectomy and digestive tract reconstruction.
|
A conventional laparoscopic pancreaticoduodenectomy performed using five trocar ports, followed by resection and reconstruction according to the standardized multicenter operative protocol.
