Robotic, Laparoscopic, or Open Hysterectomy: Surgical Outcomes by Approach in Endometrial Cancer.

STUDY OBJECTIVES

To compare patient outcomes by surgical approach in the management of endometrial cancer (EC) in Washington State from 2008 to 2013.

DESIGN

Population-based retrospective cohort study (Canadian Task Force classification II-2).

SETTING

Washington State.

PATIENTS

EC patients treated with robotic-assisted surgery (RAS), laparoscopy (LS), or laparotomy (XLAP).

INTERVENTIONS

Comprehensive Hospital Abstract Reporting System to identify patients and assess the association of surgical approach with length of stay, readmissions, and perioperative complications.

MEASUREMENTS AND RESULTS

We identified 3712 cases of EC managed with either RAS, LS, or XLAP. Mean length of stay was not clinically different for RAS (1.5 days) and LS (1.6 days) but was 2.31 days longer for XLAP compared with LS (p < .001). Odds of any readmission did not differ for either RAS or XLAP compared with LS; however, early readmissions were half as likely for RAS compared with LS (p = .014). Complications were more than 2.5 times as likely for XLAP versus LS (p < .001), whereas complications did not differ for RAS versus LS (p = .931).

CONCLUSIONS

RAS is as an alternative to LS in the treatment of EC and is preferable to XLAP. The use of RAS resulted in fewer early readmissions compared with LS and resulted in an increased proportion of cases via minimally invasive surgery.
