Comparative perioperative outcomes of articulated versus conventional straight devices in laparoscopic low anterior resection: a propensity score-matched analysis.

ABSTRACT:

Purpose

Laparoscopic low anterior resection for rectal cancer is technically challenging due to the precision required for mesorectal excision. Articulated instruments were developed to improve precision and oncological safety over conventional instruments. This study compares their perioperative outcomes.

Methods

A retrospective cohort study of 432 patients with colorectal cancer who underwent low anterior resection between August 2022 and February 2024 applied propensity score matching to minimize selection bias. Primary endpoints were circumferential resection margin (CRM), distal resection margin (DRM), and harvested lymph nodes count. Secondary outcomes included postoperative complications.

Results

Following propensity score matching, 84 matched pairs were analyz
