Segmental Posthetomy in a Four Stallions Case Series.

Abstract: Segmental posthetomy, also referred to as circumcision, reefing or posthioplasty, consists of removing a circumferential segment of the internal preputial lamina (internal preputial fold) followed by end-to-end anastomosis of skin edges. The purpose of this case series is to describe the successful outcome of segmental posthetomy for treating different diseases involving the internal or/and external preputial fold, while restoring the normal telescopic function. In this paper, we report the first case of complete degloving injury of the equine penis in the literature (case 1) and describe three different common lesions of the equine prepuce/penis (preputial scar tissue in case 2, preputial sarcoid in case 3 and penile/preputial wound in case 4). The amount of prepuce (safe minimums) that can be removed from a stallion without disrupting the proper telescopic function of the internal/external preputial fold and normal copulatory ability, has not been established. In this case series, all Equidae stallions maintained the telescopic function after preputial surgical resection. However, the surgeon must carefully evaluate every single case, especially when performing the Adam's procedure.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This study presents a case series involving four stallions (male horses) treated with a surgical procedure called segmental posthetomy, often known for treating various conditions affecting the prepuce or penis of the equine species. The surgical technique, along with its effectiveness in maintaining normal function, is discussed.

What is Segmental Posthetomy?

  • Segmental posthetomy is a surgical procedure often used in horses. Also known as circumcision, reefing, or posthioplasty, it involves the removal of a circumferential segment (a round-shaped part) of the internal preputial lamina. This is a fold of skin, also known as the preputial fold, on the penis.
  • After the removal of the problematic segment, the skin edges are joined back together through a process called end-to-end anastomosis.

Purpose and Findings of the Case Series

  • The main goal of this case series is to demonstrate the effective outcome of segmental posthetomy in treating different diseases that affect the preputial fold, while also restoring its normal function.
  • The series includes four different case studies. Case 1 is the first recorded instance in literature of a complete degloving injury to the horse’s penis. The other three cases involve common lesions of the penis or prepuce including scar tissue, a type of skin growth called a sarcoid, and a wound.
  • One of the important factors considered in the study is the safe minimum amount of prepuce that can be removed from a stallion without disrupting the normal function of the internal and external preputial fold and the horse’s copulatory ability, which until this research has not been established.

Results of the Study

  • All the studied horses maintained the normal telescopic function of their prepuce after the surgical removal. Telescopic function refers to the ability of the penis to extend from and retract into the prepuce.
  • Despite the promising results, the paper remarks on the necessity of the surgeon evaluating every case with care. This is particularly true when performing the Adam’s procedure, perhaps because of potential complications or variances in anatomy in different cases.
