Abstract:

Objective

To evaluate the perioperative outcomes of premenopausal women undergoing cystectomy or oophorectomy for ovarian endometriomas (OMAs) and other benign neoplasms.


Design

Retrospective cohort study.


Setting

Clinical database containing information from 580 US hospitals.


Patient(s)

Women 18 to 50 years old who underwent ovarian cystectomy or oophorectomy for benign indications between 2010 and 2020.


Intervention(s)

We compared procedure route, length of hospital stay, and complication rates by surgical indication (OMA vs. other benign neoplasms) and surgical procedure (cystectomy vs. oophorectomy).


Main Outcome Measure(s)

Thirty-day perioperative adverse events following adnexal surgery, including conversion to laparotomy, blood transfusion, ileus, urinary tract injury, bowel injury, readmission, and death.


Result(s)

We identified 120,208 ovarian cystectomies (28,182 OMAs and 92,026 other indications) and 53,476 oophorectomies (8,622 OMAs and 44,854 other indications). During cystectomy, patients with OMAs more commonly experienced conversion to laparotomy (5.1% vs. 3.1%) and readmission (8.5% vs. 7.1%). For oophorectomies, patients with OMAs less frequently had minimally invasive surgery (55.8% vs. 64.8%) or outpatient procedures (33.8% vs. 41.8%). Urinary tract and bowel injuries were rare. Multivariable logistic regression demonstrated that the presence of OMA predicted composite complications during cystectomy (adjusted odds ratio [aOR] 1.23, 95% confidence interval [CI] 1.18–1.28) but not during oophorectomy (aOR 1.05, 95% CI 0.99–1.12). Patients with OMAs had 1.37 times the odds of a composite complication during oophorectomy than during cystectomy (95% CI 1.28–1.47).


Conclusion(s)

Patients undergoing ovarian cystectomy for OMAs had higher rates of perioperative adverse events than patients undergoing ovarian cystectomy for other benign neoplasms. Laparotomies were performed more often during oophorectomies for OMAs than for other benign indications.
