Abstract

STUDY OBJECTIVE:

To compare intraoperative and postoperative surgical complications and outcomes between robotic-assisted and laparoscopic surgical management of endometrial cancer using a standardized classification system.

DESIGN:

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

SETTING:

An integrated health care system in Northern California.

PATIENTS:

One thousand four hundred thirty-three women with a diagnosis of complex atypical hyperplasia and endometrial cancer managed by minimally invasive hysterectomy and surgical staging from January 2009 to January 2014.

INTERVENTIONS:

Seven hundred forty-five robotic-assisted and 688 laparoscopic hysterectomies were evaluated.

MEASUREMENTS AND MAIN RESULTS:

The primary outcome was intraoperative and postoperative complications within 30 days. All complications were categorized using the Clavien-Dindo classification system. Secondary outcomes included total operative time, estimated blood loss, transfusion rates, length of stay, conversion to laparotomy, and number of pelvic and para-aortic lymph nodes retrieved. The modality of hysterectomy was not associated with either overall intraoperative complications or major postoperative complications (p > .1). However, there were significantly fewer minor postoperative complications with robotic surgery (16.6% vs 25.6%, p < .01). Statistically significant differences were also noted in the following outcomes: decreased median operative time, length of stay, estimated blood loss, conversion to laparotomy, and median number of lymph nodes retrieved in the robotic group when compared with the laparoscopic group.

CONCLUSION:

There was no difference in the rate of major complication between robotic and laparoscopic surgery using the Clavien-Dindo system of categorizing surgical complications; however, there were clinically significant differences favoring the robotic approach, including a lower rate of minor complications and conversion rate to laparotomy.
