Eksperimentel: 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.
