Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to identify the recurrent rate and pregnancy rate of advanced endometriosis after laparoscopic surgery plus GnRHa goserelin acetate treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In order to decrease endometriosis recurrence and enhance pregnancy rate after surgical therapy, it has been proposed to use a post-surgical gonadotropin-releasing-hormone agonist (GnRHa) treatment. Data on the short-term recurrence of advanced endometriosis is rare. Although operative treatment has resulted in increasing pregnancy rate comparing non surgery management for moderate to severe endometriosis, very few data of spontaneous pregnancy rate are available comparing GnRHa treatment or expectant management after surgery treatment. In this situation, the investigators conduct a prospective, randomized, controlled study to determine whether postoperative GnRHa (goserelin acetate) therapy for advanced endometriosis is effective in reducing endometriosis recurrence rate and improving reproductive outcome.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

1

Patients in this arm will be treated with goserelin depot-3.6mg plus add-back therapy.

Group Type EXPERIMENTAL

gonadotropin-releasing-hormone agonist (GnRHa) - Goserelin

Intervention Type DRUG

The patient will be managed with GnRH-a injection (Goserelin 3.6mg) every 4 weeks for 6 months plus add-back therapy (Caltrate With Vitamin D 600mg p.o. q.d.\& Livial 1.25-2.5mg p.o. q.d.) if needed.

2

The patient with advanced endometriosis(stage III-IV)confirmed histologically after conservative laparoscopic surgery will be suggested to prepare for spontaneous pregnancy rather than any medical administration.

Group Type NO_INTERVENTION
