Learning Curve on Lymph Nodes Retrieval and Postoperative Length of Hospital Stay in Robotic Rectal Cancer: A Retrospective, Observational Study.

ABSTRACT:

Background and aims

Robotic rectal cancer surgery has been introduced to reduce the difficulty and complications of the procedure. This study aims to assess the learning curve for robotic rectal cancer of individual surgeons with extensive laparoscopic rectal cancer surgery through multidimensional analyses.

Methods

Data were retrospectively collected on 156 patients who underwent robotic rectal cancer surgery by a single surgeon between January 2018 and December 2023.

Results

The operative time required for LAR can be divided into three distinct phases: an early or learning phase (1-24 cases), an intermediate or proficient phase (25-55 cases), and a late or mastery phase (56-72 cases). The study found that the learning curve for LAR and protective operative time can
