Objective The purpose of this study was to examine the recurrence rates of ovarian endometrioma, dysmenorrhea, dyspareunia,
and related complications between sclerotherapy and laparoscopic ovarian cystectomy in individuals aged 25 to 38.
Methods Eighty-eight women participated in this retrospective, single-center study between January 2020 and February
2022. Patients received either laparoscopy or sclerotherapy, depending on the opinion of the pertinent physician. In this
study, the following parameters were retrospectively analyzed in follow-up visits 2, 6 and 12 months after sclerotherapy and
laparoscopy: dysmenorrhea and dyspareunia by visual analog scale, complications following the intervention, and serial
pelvic sonograms for endometrioma cyst recurrence. Moreover, serum Anti-Müllerian hormone (AMH) level before and
6 months after sclerotherapy/surgery were analyzed. The collected data were then analyzed using R software.
Results The results demonstrate the efficiency of both sclerotherapy and laparoscopic techniques in reducing endometrioma-
related dysmenorrhea and dyspareunia over a 12-month period. There was no statistically significant difference in the
occurrence of complications and recurrence rate between these two therapies, and both are equally beneficial. Also, the rate
of AMH decline after laparoscopy was higher than sclerotherapy; however there was not a statistically significant change in
serum level of AMH in laparoscopy compared to the sclerotherapy after 6 months.
Conclusion Considering all the data, it appears that sclerotherapy, with its lower cost, shorter hospital stay, and quicker return
to activities, can be a laparoscopic alternative to endometrioma cyst removal. More studies are required.

Endometriosis is a prevalent disorder that affects around 10
percent of women in the reproductive age group all over the
world. During this condition, endometrial tissue is present
outside the uterus in places such as the ovaries, peritoneum,
and intestines [1]. Chronic pelvic pain and infertility are connected
with this condition. The most frequently mentioned
symptoms are dysmenorrhea and dyspareunia [2]. Endometriosis
patients who also have ovarian endometrioma (OMA)
make up 17 to 44% of all patients with endometriosis [3].
According to the updated American Society for Reproductive
Medicine (ASRM) classification, OMAs are found in
patients with advanced disease stages [4]; nonetheless, their
cause and management remain controversial. Regardless of
its size, endometrioma can cause ovarian injury by mechanical
straining. As it contains inflammatory factors, proteolytic
enzymes, and degrading agents, its substance induces metaplasia
and fibrosis and lowers the number of cortical-specific
stromal cells [4, 5]. Despite the considerable frequency of
endometriosis, gynecologists have always debated a treatment
that could increase fertility, relieve pain, and prevent
the disease's recurrence. Laparoscopic cystectomy is the
treatment of choice for endometriomas, with documented
recurrence rates ranging from 5 to 66.7% [6]. However, the
loss of neighboring healthy ovarian tissue by ovarian cystectomy
may result in a diminished ovarian reserve[7]. It's
also been found that 2.6% of women experience premature
ovarian failure and menopause after undergoing bilateral
ovarian cystectomy (to remove an endometrioma)[8]. Other
less invasive methods must be developed in order to avoid
postoperative complications and minimize the impact on
fertility. Ethanol sclerotherapy [9] is an alternate method
for preserving ovarian reserve. Sclerotherapy with ethanol
has been used in various organs for a long (such as thyroid,
liver, kidney, and spleen). In 1988, Akamatsu et al. used
ethanol to treat endometriomas for the first time [10]. This
minimally invasive method removed the cyst by disrupting
the epithelial lining of the cyst, resulting in inflammation
and fibrosis [11]. Sclerotherapy following aspiration was
found to be more effective than aspiration alone in terms of
recurrence (8 to 14.9 percent and 83.3 percent, respectively)
[12, 13]. The reported recurrence rates following sclerotherapy,
after 12 to 24 months of follow-up, vary from 0
to 62.5%, depending on the procedure employed [10, 14,
15]. This conservative approach may be effective in alleviating
symptoms while also saving money. Endometriosis
is accompanied by dysmenorrhea, dyspareunia, pelvic
pain, and infertility. Endometriosis is the most prevalent
cause of secondary dysmenorrhea, which has a detrimental
influence on an individual's quality of life and productivity.
Endometriosis-related dysmenorrhea is treated with antiinflammatory
drugs, GnRH agonists, danazol, and surgery.
Each strategy offers benefits and drawbacks that can be
utilized based on the patient's situation [16]. The purpose
of this retrospective study was to investigate the degree of
pain (dysmenorrheal and dyspareunia), the rate of recurrence
of OMA, serum AMH level and related complications following
sclerotherapy vs. laparoscopic ovarian cystectomy in
patients aged 25–38 years.
