Ring Amputation
ОглавлениеOften a client will choose to cull rather than allow treatment. Because these bulls are the victims of severe price discrimination, I will offer a salvage‐type procedure. A large swine rectal (prolapse) ring or short length of PVC pipe is placed within the preputial lumen dorsal to the lesion and a band is placed around the prepuce over the pipe. This will amputate the damaged prepuce, but fibrosis and stenosis will likely occur. Alternatively, holes can be drilled in the PVC pipe prior to placement and, rather than a band, heavy (6‐mm) Braunamid™ is utilized in an overlapping pattern. The overlapping suture serves to both fix the tube and provide for hemostasis when the end of the prepuce is amputated [3]. This is the “ring amputation” procedure and can be performed with the bull standing, utilizing local analgesia and chute restraint [1]. This procedure usually results in some degree of stricture. It should be noted that correction with the circumcision technique remains an option for bulls in which the ring amputation results in a stricture and thus it might be considered for the client that desires a more economical option than lengthy medical treatment prior to surgical correction by circumcision (Figures 19.27 and 19.28).
