Laparoscopic treatment of endometriosis and predictors of major complications: A retrospective cohort study.

Complications following laparoscopic treatment of suspected endometriosis could not be predicted by preoperative patient characteristics or surgical findings of advanced endometriosis. Adhesiolysis, ureterolysis, and an increased number of total procedures may be predictive of perioperative complications, suggesting that surgical complexity as measured by the procedures performed, rather than the disease severity, may increase the risk of a complication compared with women who do not undergo these procedures.
