OBJECTIVES: To determine risk factors associated with conversion to laparotomy
for women undergoing robotic gynecologic surgery. METHODS: The medical records of
459 consecutive robotic surgery cases performed between December 2006 and October
2011 by 8 different surgeons at a single institution were retrospectively
reviewed. Cases converted to laparotomy were compared to those completed
robotically. Descriptive statistics were used to summarize the demographic and
clinical characteristics. RESULTS: Forty of 459 (8.7%, 95% CI 6.3%-11.7%)
patients had conversion to open surgery. Reason for conversion included poor
visualization due to adhesions (13), inability to tolerate Trendelenburg (7),
enlarged uterus (7), extensive peritoneal disease (5), bowel injury (2), ureteral
injury (1), vascular injury (1), bladder injury (1), technical difficulty with
the robot (2), and inability to access abdominal cavity (1). 5% of cases were
converted prior to docking the robot. On univariate analysis, preoperative
diagnosis (p=0.012), non-White race (p=0.004), history of asthma (p=0.027), ASA
score (p=0.032), bowel injury (p=0.012), greater BMI (p<0.001), need for blood
transfusion (p<0.001), and expected blood loss (p<0.001) were associated with
conversion. On multivariate analysis, non-White race (OR 2.88, 95% CI 1.39-5.96,
p=0.004), bowel injury (OR 35.40, 95% CI 3.00-417.28, p=0.005), and increasing
BMI (OR 1.06, 95% CI 1.03-1.09, p<0.001) were significantly associated with
increased risk for conversion. Prior surgery was not associated with conversion
to open surgery (p=0.347). CONCLUSION: Conversion to laparotomy was required for
8.7% of patients undergoing robotic surgery for a gynecologic indication.
Increasing BMI and non-white race were identified as the two preoperative risk
factors associated with conversion.
