This pilot study compared menstrual characteristics in Korean women with ovarian endometrioma to those with other benign ovarian tumors and found no significant differences, though low BMI was associated with endometriosis.

This pilot study compared menstrual characteristics in 95 premenopausal Korean women undergoing laparoscopy for ovarian endometrioma (n=46) versus other benign ovarian tumors (n=49), collecting cycle length, regularity, menstrual duration, menstrual bleeding amount using PBAC, and dysmenorrhea severity by visual analogue scale from medical records at admission. Women with endometrioma had similar cycle regularity, cycle length, menstrual duration, and PBAC-assessed menstrual bleeding amount compared with those without endometriosis, but reported significantly higher pain scores; BMI was lower and preoperative hemoglobin was lower in the endometrioma group. The authors note important limitations including lack of menarche data for many participants and uncertainty about whether their Korean PBAC values reflect a normal baseline, potentially complicating interpretation and comparisons to prior studies using different PBAC cut-offs. This paper is centrally about endometriosis — it evaluates whether menstrual characteristics differ between Korean women with and without ovarian endometrioma, including PBAC-measured bleeding and dysmenorrhea.

Abstract

OBJECTIVE: This study aimed to determine whether the menstrual characteristics are different in Korean women with or without ovarian endometrioma. METHODS: We selected 95 premenopausal women aged below 39 years who underwent laparoscopic surgery for ovarian endometrioma (n=46) or other benign ovarian tumors (n=49) between April 2016 and February 2017. We excluded those with uterine diseases that could potentially affect the menstrual characteristics and those on anticoagulants or hormonal medication. At admission, menstrual characteristics such as cycle length, cycle regularity, and menstrual duration, were collected. In addition, amount of menstrual bleeding and severity of dysmenorrhea were recorded using a pictorial blood loss assessment chart (PBAC) and visual analogue scale, respectively. RESULTS: =0.005) in women with ovarian endometrioma. CONCLUSION: We found that the menstrual characteristics between women with ovarian endometrioma and women with other benign ovarian tumors were similar. We also observed that low BMI may be one of the risk factor for endometriosis.
