[The electrosurgical treatment of endometrial cysts in the mare].

The research article discusses a minimally invasive surgical technique for treating endometrial cysts in mares, which can hinder pregnancy. The method involves cauterizing and removing the cysts. The procedure was tested on five barren mares and resulted in successful pregnancies in three of them.

Research Objective

• The study aims to explore a minimally invasive surgical procedure for the removal of endometrial cysts in mares. These cysts pose challenges to the mares’ successful pregnancy by interfering with embryo migration and placenta development. They can also create confusion by presenting false-positive results in early pregnancy tests.

Research Method

• The procedure involves placing an endoscope into the mares.
• A wire is then inserted through the biopsy channel and positioned around the base of the cyst.
• Next, cauterization, a process of burning that stops bleeding and cuts through tissue, is used to sever the cyst from the endometrium.
• The cyst is finally removed with the help of forceps.
• The operation was tested on five barren mares during their non-reproductive period (anoestrous) from October through to February.

Research Findings

• The technique was successful in treating endometrial cysts in the lumen, an area within the uterus.
• Of the five barren mares treated, three were successfully impregnated during their next estrous period, indicating a positive impact of the procedure on fertility.

Research Implications

• The successful removal of endometrial cysts via this minimally invasive technique offers a promising solution for enhancing the pregnancy success rates in mares.
• By reducing the risk of false-positive early pregnancy tests due to the presence of these cysts, the procedure might also improve reproductive management of the mares.
