Laparoscopic and Robotic-Assisted Hysterectomy for Uterine Leiomyomas: A Comparison of Complications and Costs.

OBJECTIVE

Robotic surgery is increasingly being used for treatment of malignant and benign gynaecologic diseases. The purpose of our study is to compare patient perioperative complications and costs of laparoscopic versus robotic-assisted hysterectomy for uterine leiomyomas.

METHODS

A retrospective cohort study using the Nationwide Inpatient Sample database from the United States was conducted, comparing patients who underwent robotic-assisted hysterectomy and laparoscopic hysterectomy (total laparoscopic hysterectomy and laparoscopic-assisted vaginal hysterectomy) for uterine fibroids between 2008 and 2012. Baseline characteristics were compared between the two groups, and logistic regression was used to compare postoperative outcomes between laparoscopic and robotic approaches. Direct costs were compared between the two groups using linear regression models.

RESULTS

Over a five-year period, the total number of hysterectomies performed increased. Patients undergoing robotic hysterectomy were older and had more comorbidities. In adjusted analyses, women who underwent robotic surgery were more likely to have respiratory failure (0.71% vs. 0.39%; P < 0.0108), postoperative fever (1.05% vs. 0.67%, P < 0.0002), and ileus (1.76% vs. 1.3%; P < 0.0060), and less likely to require transfusions (3.4% vs. 3.96%; P < 0.0037). Robotic surgery was consistently more expensive, with a median cost of $33 928.00 compared with $23 753.00 for laparoscopic hysterectomy.

CONCLUSION

While there are only slight differences in postoperative complications between laparoscopic-assisted hysterectomy and robotic-assisted hysterectomy, robotic-assisted hysterectomy is associated with considerably greater direct costs. Unless specific indications for robotic-assisted hysterectomy exist, laparoscopic-assisted hysterectomy should be the preferred approach for minimally invasive surgical treatment of leiomyomas.
