Overview

Two-center retrospective study reveals unfavorable pelvic anatomy impairs functional outcomes after laparoscopic but not robotic rectal resection, highlighting robotic advantages in narrow pelvises.

Key Points

  • To compare bowel, urinary, and quality-of-life outcomes between laparoscopic and robot-assisted rectal resection and assess the functional impact of pelvic anatomical parameters.
  • Retrospective two-center analysis of N=87 patients undergoing sphincter-sparing rectal resection (48 laparoscopic, 39 robot-assisted).
  • Evaluated functional results using the LARS, IPSS, FACT-C, and SF-36 questionnaires alongside preoperative pelvic MRI pelvimetry.
  • Unfavorable pelviometric dimensions correlated moderately with worse overall functional outcomes across the combined cohort.
  • Stratified analysis revealed significant negative anatomical correlations in laparoscopic resections that were entirely absent in the robot-assisted group.
