title: Obesity and perioperative pulmonary complications in robotic gynecologic surgery.
abstract: OBJECTIVE
  Robotic gynecological surgery is feasible in obese patients, but there remain concerns about the safety of this approach because the positioning required for pelvic surgery can exacerbate obesity-related changes in respiratory physiology. The objective of our study was to evaluate pulmonary and all-cause complication rates in obese women undergoing robotic gynecological surgery and to assess variables that may be associated with complications.
  
  
  METHODS
  A retrospective chart review was performed on obese patients (body mass index of ≥30 kg/m(2)) who underwent robotic gynecological surgery at 2 academic institutions between 2006 and 2012. The primary outcome was pulmonary complications and the secondary outcome was all-cause complications. Univariate and multivariate logistic regression analyses were used to determine the associations between patient baseline variables, operative variables, ventilator parameters, and complications.
  
  
  RESULTS
  Of 1032 patients, 146 patients (14%) had any complication, whereas only 33 patients (3%) had a pulmonary complication. Median body mass index was 37 kg/m(2). Only age was significantly associated with a higher risk of pulmonary complications (P = .01). Older age, higher estimated blood loss, and longer case length were associated with a higher rate of all-cause complications (P = .0001, P < .0001, and P = .004, respectively). No other covariates were strongly associated with complications.
  
  
  CONCLUSIONS
  The vast majority of obese patients can successfully tolerate robotic gynecological surgery and have overall low complications rates and even lower rates of pulmonary complications. The degree of obesity was not predictive of successful robotic surgery and subsequent complications.
