Complications and risk factors of castration with primary wound closure: Retrospective study in 159 horses

摘要

Castration with primary wound closure reportedly has lower complication rates and shorter recovery periods compared to castration with second intention healing. However, little is known about risk factors associated with complications using primary wound closure. Medical records of 159 horses castrated and having primary wound closure were reviewed. Main short-term complications were: scrotal hematoma in 12 horses (7.6%), signs of colic in 6 horses (3.8%), fever in 4 horses (2.5%), and peri-incisional edema in 3 horses (1.9%). As for long-term complications, 24 out of 105 (23%) horses sustained some form of edema. One horse was euthanized because of a suspected inguinal abscess. Among tested parameters, horses aged 3 to 6 years old and French trotters appeared to be more at risk of developing complications. Intraoperative ligation of the cremaster muscle and use of electrocautery prevented complications. Overall, client satisfaction was excellent (98%).
