Management of ruminal fistula in a cross-bred cow

摘要

A six year old crossbred cow was referred to polyclinic with a small ruminal fistula at mid of the left 10th intercostal space and multiple fractures of 10-13 ribs. It was reported that the injury was inflicted by a bull during fighting about two months ago. The history showed that the cow was treated by local veterinarian and few pieces of fractured ribs were removed. After 15 days of treatment, animal developed ruminal fistula discharging undigested contents. Clinical examination revealed a 9" long broken piece of 13th rib placed horizontally was persistently piercing the fistulated site. It was decided to perform laparotomy to remove floating piece of 13th rib before repair of the fistula. The animal was fasted overnight prior to surgery and prepared for aseptic surgery. Sedation with triflupromazine hydrochloride @ 10mg/100 kg body weight I/M and local infiltration of 2 percent lignocain hydrochloride was carried out. A 4" long vertical incision was made at left paralumber fossa just behind 13th rib. Broken piece of rib was removed after separation of adhesions by blunt dissection. Laparotomy incision was closed in routine manner.
