This short-term single-center observational study evaluated dienogest 2 mg once daily over 3 months in 56 young women (ages 15–35) with imaging- and/or laparoscopically diagnosed endometriosis and pelvic pain, assessing changes in pain scores and endometrioma size, with follow-up at 1 and 3 months. Most participants reported rapid pain relief, including 67.8% within 2–5 days and 73.2% achieving significant pain relief (>30%) by 3 months; major side effects were not noted. Endometrioma regression was less consistent, with >50% cyst size reduction occurring in 5.3% at 1 month and 12.5% at 3 months, despite the report that cysts did not grow during treatment, and the study’s single-center design and lack of a control group were not addressed as a stated limitation in the provided text. This paper is centrally about endometriosis — it reports how dienogest affects pain and endometrioma size in young women with endometriosis.

Abstract

IntroductionEndometriosis associated pelvic pain (EAPP) is the most common complaint of patients with endometriosis.

The effect of dienogest was also seen on size of endometrioma. Patients were followed up at 1 and 3 months.Results and discussionOut of 56 patients, 38 (67.8%) patients reported their pain relief within 2-5 days after starting dienogest. Out of 41 patients (73%) who had severe pain at enrollment, only 1 patient (1.79%) complained of severe pain at the end of 1 month with dienogest. Successful reduction in endometriotic cyst size (>50%) was seen in 3 patients (5.3%) at the end of 1 month with dienogest.

Abstract

Introduction Endometriosis associated pelvic pain (EAPP) is the most common complaint of patients with endometriosis. Nearly, 70% of females with endometriosis present with EAPP while endometriomas are found in 17–44% of patients.

Material and methods

A short-term single centre study was carried out in 56 patients in the age group of 15–35 years with complaints of pain and diagnosed as endometriosis either by imaging studies and/or by laparoscopy was given dienogest 2 mg OD, and effect of treatment was seen as improvement of pain score over a period of 3 months. The effect of dienogest was also seen on size of endometrioma. Patients were followed up at 1 and 3 months.

Results

and Discussion Out of 56 patients, 38 (67.8%) patients reported their pain relief within 2–5 days after starting dienogest. Out of 41 patients (73%) who had severe pain at enrollment, only 1 patient (1.79%) complained of severe pain at the end of 1 month with dienogest. Successful reduction in endometriotic cyst size (>50%) was seen in 3 patients (5.3%) at the end of 1 month with dienogest. Out of 56 patients, 41 patients (73.2%) had significant pain relief (>30%) at three months of treatment. At the end of 3 months, seven patients (12.5%) had significant cyst size reduction (>50%) with dienogest. No major side effects were noted.

Conclusion

Dienogest is well tolerated drug for endometriosis showing significant relief of pain. However, it was seen that though endometriomas did not grow during treatment, significant regression was uncommon. Similar content being viewed by others
