Splenectomy in the horse.

The research article presents the successful removal of spleens from two older horses in order to assist with experimental studies related to Babesia equi, a parasitic infection. The procedure was conducted via a resection of a part of the 17th rib, which was found to result in fewer complications than the removal of part of the 16th rib.

Objective and Methodology

• The researchers wanted to explore the removal of spleens (splenectomy) in horses, mainly to enable further experimental studies on the infection caused by Babesia equi, a parasite that causes equine piroplasmosis.
• The experiments were performed on two aged horses, not on young or mature horses. This could be due to a variety of reasons, such as the older horses’ larger organ size or their greater ability to withstand postoperative complications.

Approach and Findings

• In order to perform the splenectomy, the researchers adopted an approach involving the resection, or surgical removal, of a part of the 17th rib of the horses.
• The choice of the 17th rib was primarily due to the researchers’ goal to avoid complications that could arise if the 16th rib was removed instead. These potential complications are not specified but could include factors such as surgical accessibility, risk of damage to adjacent organs, or postoperative recovery.
• The study found that this approach was successful, implying that the resulting splenectomies were performed without causing undue harm or complications for the horses.

Implications of the Research

• The successful conduct of these splenectomies suggests the 17th rib resection as a viable and relatively safe method for spleen removal in horses.
• The research opens up opportunities for investigations involving the spleen in species-specific diseases, like Babesia equi infection in horses, which may be instrumental in understanding the disease’s dynamics and developing targeted treatments.
