Improvements and challenges in intraperitoneal laparoscopic para-aortic lymphadenectomy: The novel "tent-pitching" antegrade approach and vascular anatomical variations in the para-aortic region.

ABSTRACT:

Introduction

This study introduces and compares a new intraperitoneal laparoscopic para-aortic lymphadenectomy method to reach the level of the renal vein, the "tent-pitching" antegrade approach with the retrograde approach in gynecological malignancy surgeries in terms of success rate, complication incidence, and the number of lymph nodes removed. It focuses on the feasibility, safety, and effectiveness. Meanwhile, this article reports on the vascular anatomical variations discovered in the para-aortic region to enhance surgical safety.

Material and methods

This was a retrospective cohort study including patients undergone laparoscopic para-aortic lymphadenectomy at a single center from January 2020 to December 2023 for high-risk endometrial and early-stage ovarian cancer.
