Study to Compare Peritoneal Ablation by Excision Only and Excision With the Use of an Adhesion Barrier

Endometriosis is a common disease of women in the reproductive age and is an important cause for female infertility. Endometriosis is often associated with the development of adhesions which further compromises the fertility of the affected women. The main purpose of this study is to investigate the pregnancy rate one year after excision of endometriosis and application of GnRH-analogues (Gonadotropin-releasing hormone) for 3 month. Half of the patients will receive traditional endometriosis treatment with the excision of the endometriotic lesions only. The other half will additionally receive a gel which can reduce adhesion formation (Hyalobarrier®). Further study objective is the investigation in the development of different types of endometriosis-associated pain over a period of one year. Potential study participants are women with endometriosis-associated pain and with a desire to have children. It will be investigated in the study if the use of Hyalobarrier® will result in a higher pregnancy rate due to reduced adhesion development.
