Obesity and mid-term outcomes following robotic cholecystectomy


      • A retrospective review of robotic cholecystectomy (RC) in obese patients.
      • Clinical outcomes of 617 RC were collected and analyzed.
      • Outcomes were comparable to laparoscopic literature on obese patients.
      • Higher BMI classes and complicated gallbladders were associated with complications.



      As obese adults often suffer from gallbladder disease, more data on postoperative outcomes following robotic cholecystectomy(RC) is needed.


      RC candidates with a body mass index(BMI) > 30 kg/m2 were included. Postoperative course was documented and analyzed. A logistic regression analysis was performed to determine possible risk factors associated with complications.


      617 patients with a BMI of 35.9 ± 6.4 kg/m2 were included of which 65 had complicated gallbladders (gangrenous, fistulated, or abscessed). Eight cases were converted to open. Sixty-five(10.5%) patients revisited the emergency department within 30 days, and 35(5.7%) were readmitted to the hospital. Average follow-up time was 35 months. Fifty(9.1%) patients experienced complications, eight(1.5%) underwent reoperation. Postoperative complications were associated with chronic obstructive pulmonary disease[p < 0.001, Odds-Ratio(OR):8.418, 95%-Confidence-interval(CI):4.029–17.585], BMI(p < 0.024, OR:1.045, 95%-CI:[1.006–1.086]), class-III obesity (p < 0.021, OR:2.221, 95%-CI:[1.126–4.379], and complicated gallbladders (p < 0.001, OR:3.659, 95%CI:[1.665–8.041]).


      This is the first study to establish a link between higher obesity classes and postoperative complications following RC.
