Robotic Versus Laparoscopic Partial Mesorectal Excision for Cancer of the High Rectum: A Single-Center Study with Propensity Score Matching Analysis.

Background: The role of robotic surgery for partial mesorectal excision (PME) in patients with high rectal cancer (RC) remains unexplored. This study aimed to compare the operative and postoperative outcomes of robotic (R-PME) versus laparoscopic (L-PME) PME for high RC.

Methods: This was a single-center propensity score cohort study of consecutive patients diagnosed with RC in the high rectum (>10 to 15 cm from the anal verge) who underwent surgery between September 2012 and May 2019.
