Mature teratomas were significantly more common in elective cases (89% vs. 52%) but corpus luteum cysts were more common in emergency cases (0% vs. 32%). The rates of laparoscopic surgery (98.2% vs. 52.0%) and ovarian conservation (99.1% vs. 80.0%) were significantly higher, and post\u2010surgical hospitalization (4.6\u2009\u00b1\u20091.3 vs. 9.8\u2009\u00b1\u200910.5\u2009days) was significantly shorter in elective than in emergency cases.
