Evaluating body mass index ’s impact on Da Vinci Robotic rectal cancer surgery, a retrospective study

This study assessed the implications of BMI on short outcomes and postoperative complications, highlighting its unique role in the outcomes. Retrospective analysis of 119 patients who underwent robotic-assisted surgery for rectal cancer (January 2022 to March 2023). Patients grouped by BMI: normal weight (BMI  <  23.9 kg/m2), overweight (BMI  ≥ 23.9 kg/m2 and BMI  <  27.9 kg/m2), and obese (BMI  ≥ 27.9 kg/m2). Investigated BMI ’s impact on surgical outcomes and postoperative complications. Statistically significant differences (P <  0.05) in Clavien–Dindo, ASA scores. The obese group had a longer time to flatus (P = 0.002) and a higher re-operation rate than other groups (P = 0.01). The overweight group had a higher anastomotic fistula rate than the obese group. Overall complications showed no significant differenc es among BMI cohorts (P = 0.0295). There were no significant differences in TNM stages and comorbidities. BMI had no significant impact on overall postoperative complications in robotic surgery for rectal cancer. However, higher BMI correlated with a longer time to flatus and increased re-operat ion rate.
