ARTICLE HIGHLIGHTS
Research background
D2 lymph node dissection of station 8p lymph nodes in gastric cancer is technically difficult.
Research motivation
How to safely and effectively dissect the lymph nodes superior to the pancreas during gastrectomy remains a clinical challenge for surgeons.
Research objectives
The current study introduced a new procedure for dissection of the lymph nodes superior to the pancreas.
Research methods
Fifty-one patients who underwent laparoscopic gastrectomy for gastric cancer were retrospectively included with utilization of a new procedure for superior pancreatic lymphadenectomy (LND) with portal vein priority via the posterior common hepatic artery approach (SPLD-PPPH) based on a newly defined portal triangle.
Research results
All the procedures were safely performed. Among the 51 patients, 9.8% had lymph node metastasis at station 8p. Fourteen lymph nodes were harvested at station 8p, with an incidence of nodal metastasis of 14.3%.
Research conclusions
The new procedure of SPLD-PPPH is safe and effective for D2+ LND during laparoscopic radical gastrectomy.
Research perspectives
This new approach should be further evaluated with larger patient numbers.
