Rectal tear repair using barbed suture in the horse.

Abstract

To describe the repair utilizing integral-anchor barbed suture in equine rectal tears. 3 horses aged 3 to 10 years old with grade 3 to 4 rectal tears. Grade 3 and 4 rectal tears were referred for surgical repair immediately after iatrogenic tearing or tearing during parturition. Integral-anchor barbed suture (Stratafix Symmetric PDS Plus, size 1, 18" CT-1) was placed using long-handled instruments or hand closure depending on the accessibility and visibility of the tear. Closure of grade 3 tears was performed using a continuous appositional pattern. A horizontal mattress pattern was performed in the grade 4 tear. No other surgical procedures were performed. Two grade 3 tears were successfully repaired with no complications and discharged from the hospital. One grade 4 tear was successfully repaired; however, 4 days post-surgery partial dehiscence of the suture site occurred, and the horse was euthanized. Grade 3 rectal tears were repaired successfully by using an integral-anchor barbed suture. No post-operative complications were reported. Blind hand suturing could be performed in cranial locations when the laceration could not be made visible. For grade 4 rectal tears, additional surgical procedures beyond barbed suture closure are needed.
