. Robotic surgery has gained increasing popularity over the past 2 decades. However, factors including patient comorbidities and tumor characteristics are still crucial factors for outcomes of surgery. In this study, we evaluated the impact of body mass index (BMI) on perioperative outcomes in patients who underwent robotic adrenal surgery. Between May 2012 and November 2017, 66 consecutive patients who underwent robotic adrenalectomy were included in this study. Patients were divided into 2 groups based on their BMI: nonobese (<30 kg/m) and obese (≥30 kg/m). Additionally, patient demographics, tumor size, total operative time, docking time, console time, estimated blood loss, conversion to open, complications, additional analgesia requirement, length of hospital stay, and rough costs were evaluated. Of the 66 patients, a total of 26 patients were obese (30%). Between study groups, the median BMI was calculated as 26 (18-29) and 33 (30-57). The groups were similar in terms of age, gender, American Society of Anesthesiologists scores, and previous history of abdominal surgery. Likewise, there were no significant differences between groups regarding total operative time ( = .085), docking time ( = .196), console time ( = .211), estimated blood loss ( = .180), complications ( = .991), length of hospital stay ( = .598), and rough costs ( = .468). Five cases were converted to open surgery. Nonobese cases required additional analgesia ( = .007). We had no unexpected hospitalizations in either group. . Guidelines express the advantages of robotic surgery in obese patients. No statistically significant differences were detected between the 2 groups except for the additional analgesia required in nonobese patients.
