Comparative analysis of robotic and laparoscopic surgery for mid and low rectal cancer in patients with varied body mass indexes: evaluating of short-term outcomes.

Abstract

The main aim of this study was to evaluate and contrast the efficacy of robotic and laparoscopic surgical procedures in the treatment of low and mid rectal cancer in different BMI (body mass index) groups. The clinical records of patients who had laparoscopic or robotic proctectomy at a single center between December 2019 and August 2023 were analyzed. Then we utilized a classification framework to categorize individuals based on their BMI into three unique groups: non-obese, overweight, and obese. The short-term efficacy was evaluated. A consecutive sample of 1413 patients was included in this retrospective investigation. 1158 people out of the total sample chose laparoscopic surgery, whereas 255 people chose robotic surgery. In the group of obese people, robotic surgery showed a statistically significant decrease in blood losscompared to laparoscopic surgery (P = 0.026). People who were overweight or obese were in the hospital for a shorter amount of time after robotic surgery than after laparoscopic surgery (P = 0.033 and P = 0.031, respectively). People with different BMIs in the robotic surgery group took less time to have a flatus passage and oral intakethose in the laparoscopic surgery group. Oncological outcomes and the frequency of complicationswere comparable between the two treatments with different BMIs. Surgical resection of patients undergoing low-anterior surgery may benefit from a robotic approach, particularly in overweight and obese patients.
