Histological Assessment of Tissue Penetration Depth of Argon Beam Coagulation in Ovarian Endometriomas
Histological Assessment of Tissue Penetration Depth of Argon Beam Coagulation in Ovarian Endometriomas: A Prospective Pilot Study
Source: ClinicalTrials.gov · Last updated 17 Jul 2026
Brief summary (registry, in English)
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.
