Ovarian damage after laparoscopic endometrioma excision might be related to the size of cyst

Ovarian damage after laparoscopic endometrioma excision is more severe in ovaries from which an endometrioma 4 cm in diameter has been excised.

Abstract

Objective:

To investigate the relationship between the size of an excised endometrioma and the magnitude of damage to the ovary after the surgery.

Design:

A retrospective, controlled study.

Setting:

A university hospital.

Patient(s):

Eighty-five women with a history of laparoscopic excision of unilateral endometrioma who underwent in vitro fertilization (IVF).

Intervention(s):

IVF-embryo transfer procedures.

Main Outcome Measure(s):

Antral follicle counts (AFC), number of dominant follicles (follicles ≥15 mm), and number of oocytes retrieved.

Result(s):

In the group with cyst diameters of ≥4 cm and group with cyst diameters of <4 cm, the AFC, number of dominant follicles, and number of oocytes retrieved were decreased in the operated ovaries when compared with those in intact ovaries; in the former group, a statistically significant reduction was observed. The differences of AFC, number of dominant follicles, and number of oocytes retrieved from both ovaries were further compared among the two groups: the decrease in the group with cyst diameters of ≥4 cm was higher than in the group with cyst diameters of <4 cm. After adjusting for age and AFC in intact ovaries, similar results were obtained, although AFC only showed a tendency. In addition, the receiver operating characteristic curve analysis revealed a statistically significant, positive correlation between the size of excised cysts and the incidence of fewer than four oocytes retrieved from an operated ovary. Conclusion(s):

The magnitude of the ovarian damage after laparoscopic endometrioma excision might be related to the size of cyst; the damage to ovaries is more severe when an endometrioma ≥4 cm is excised.
