Multicenter retrospective study of complications and risk factors associated with castration in 106 pet pigs

摘要

Castration of pet pigs is becoming a commonly performed procedure. However, little information is available regarding surgical techniques and complications. Medical records of 106 pet pigs admitted to 3 teaching hospitals for castration were reviewed. All descended testicles were approached via pre-scrotal skin incisions, which were either closed (59.4%) or left open (22.6%). The inguinal rings were closed in 42% of cases. Of the 106 pet pigs, 4.7% developed a complication after surgery, which consisted of peri-incisional swelling. Pigs which underwent inguinal ring closure were 6.6 times more likely to develop a post-operative complication (confidence interval: 1.16 to infinity, P = 0.035). Age and weight at time of castration were not significantly associated with complications (P = 0.698 and P = 0.685, respectively). The results from this retrospective study suggest that castration in pet pigs is a safe procedure with a minimal rate of complications.
