The impact of body mass index on outcomes in robotic colorectal surgery: a single-centre experience

AbstractObesity is an independent risk factor for postoperative morbidity and mortality in laparoscopic colorectal surgery (LCRS). The technological advantages of robotic colorectal surgery (RCRS) may allow surgeons to overcome the limitations of LCRS in obese patients, but it is largely unknown if this translates to superior outcomes. The aim of this study was to compare perioperative, postoperative and short-term oncological outcomes in obese (BMI  ≥ 30.0 kg/m2) and non-obese (BMI  <  30 kg/m2) patients undergoing RCRS in a university teaching hospital. Demographic, perioperative and postoperative data along with short-term oncological outcomes of obese and non-obese patients that underwent RCRS for both benign and malignant colorectal disease were identified from a prospectively maintained database. A total of 107 patients (34 obese, 73 non-obese) underwent RCRS over a 4-year period. No statistically significant differences in the incidence of complications, 30-day reoperation, 30-day mortality, conversion to open surgery, anastomotic leak or length of inpatient stay were demonstrated. Obese patients had a significantly higher rate of surgical site infection (SSI) (p  <  0.0001). Short-term oncological outcomes in both groups were favourable. There was no statistically significant difference in median duration of surgery between the two cohorts. The results demonstrate that obese patients undergoing RCRS in this institution experience similar outcomes...
