简要总结

The goal of this clinical trial is to evaluate the depth of tissue penetration of Argon Beam Coagulation (ABC) during laparoscopic surgery for ovarian endometriomas. Researchers want to determine how deeply ABC affects ovarian tissue and to generate data on the safety of this surgical technique.

Participants will undergo standard laparoscopic surgery for ovarian endometriomas. During the planned surgical procedure, Argon Beam Coagulation will be applied to the ovarian surface according to the study protocol. The treated tissue will subsequently be excised as part of the planned surgery and analyzed histologically to measure the depth of tissue penetration.

详细描述

Endometriosis is a chronic inflammatory disease affecting approximately 10% of women of reproductive age. Ovarian endometriomas are a common manifestation of the disease and frequently require surgical treatment. Conventional cystectomy may unintentionally remove healthy ovarian tissue, potentially reducing ovarian reserve and affecting future fertility. Tissue-preserving surgical techniques are therefore of increasing clinical interest.

Argon Beam Coagulation (ABC) is an energy-based surgical technology that allows non-contact coagulation using ionized argon gas. Although ABC is increasingly used in endometriosis surgery, limited histological evidence is available regarding the depth of tissue penetration produced by this technique.

This prospective, single-center interventional study will enroll women undergoing laparoscopic surgery for ovarian endometriomas at the University Hospital Bern. During the planned surgical procedure, Argon Beam Coagulation will be applied to the ovarian surface according to a standardized protocol. The treated tissue will subsequently be excised during the same operation and processed for histological examination.

The primary objective of the study is to quantify the histological depth of tissue penetration of Argon Beam Coagulation in ovarian tissue. Secondary objectives include evaluating the consistency of tissue penetration and generating data that may support the safe use of ABC as a tissue-preserving surgical technique in the management of ovarian endometriomas.
