Laparoscopic Hysterectomy Outcomes: Hospital vs Ambulatory Surgery Center

Background and Objective: Compare operative outcomes of laparoscopic hysterectomy in an outpatient hospital setting versus freestanding ambulatory surgery center. Methods: Retrospective cohort study of two groups in an outpatient hospital surgery department and freestanding ambulatory surgical center, both serving the Washington, DC area. Women, 18 years or older, who underwent laparoscopic hysterectomy for benign conditions in an outpatient hospital setting between 2011 and 2014 (n = 821), and at an ambulatory surgery center between 2013 and 2017 (n = 1210). Laparoscopic hysterectomy with retroperitoneal dissection and early ligation of the uterine arteries at the origin, performed by gynecologic surgical specialists from a single practice. Patient characteristics, medical history, uterine weight, pathology, operating times, estimated blood loss, and complications were analyzed. Results: The mean uterine size between settings was not significantly different (Ambulatory Surgery Center, 349.4 g; Hospital, 329.7 g). The largest uteri removed at the surgery center was 3500 g; at the hospital it was 2489 g. The surgery center had a shorter average operating time than the hospital (53.7 and 61.3 minutes, respectively; P < .001). Intraoperative and postoperative complication rates were not significantly different between settings (2.7% and 3.7%, surgery center; 2.1% and 4.8%, hospital). There were two hospital transfers from the surgery center: 1 for blood transfusion, and 1 for low oxygen saturation. Same-day discharge occurred in 99.8% of surgery center patients versus 88% hospital patients. Conclusions: Laparoscopic hysterectomy can be performed safely and effectively by skilled surgeons at a freestanding ambulatory surgery center, even in complex cases with large uteri.
