Purpose: To analyze the feasibility and outcomes of robotic rectal cancer surgery in obese patients. Methods: From 2005 to 2012, 101 consecutive rectal cancers operated robotically were enrolled in a prospective database. Patients were stratified into obese (BMI ≥ 30 kg/m2) and non-obese (BMI < 30 kg/m2) groups. Operative, perioperative parameters, and pathologic outcomes were compared. Data were analyzed using SPSS 22.0, while statistical significance was defined as a p value ≤ .05. Results: There were 33 obese patients (mean BMI 33.8 kg/m2). Patients were comparable regarding gender, T stage, and type of operation. Operative time and blood loss were higher in the obese group; only operative time was statistically significant. The conversion rate, length of stay, and anastomotic leak rates were similar. Circumferential margin positivity and lymph node yield were comparable. Disease free and overall survivals at 3 years were 75.8% versus 80.9% and 84.8% versus 92.6%, respectively for obese and non-obese subgroups. Conclusions: Robotic surgery for curative treatment of rectal cancer in the obese is safe and feasible. BMI does not influence conversion rates, length of stay, postoperative complications, and quality of the specimen or survival when the robotic platform is used.
