Response to early repeat celiotomy in horses after a surgical treatment of jejunal strangulation.

Objective: To determine the outcome after early repeat celiotomy in horses operated for jejunal strangulation.

Study Design: Retrospective case series.

Animals: Horses (n = 22) that underwent repeat celiotomy for postoperative reflux (POR) and/or postoperative colic (POC) that did not improve within 48 hours from onset after initial surgical treatment of strangulating jejunal lesions by jejunojejunostomy (n = 14) or no resection (n = 8).

Effect of exercise and osteochondral injury on synovial fluid and serum concentrations of carboxy-terminal telopeptide fragments of type II collagen in racehorses.

Objective: To investigate the effects of exercise and osteochondral injury on concentrations of carboxy-terminal telopeptide fragments of type II collagen (CTX-II) in synovial fluid (SF) and serum of Thoroughbred racehorses and to compare findings with radiographic and arthroscopic scores of joint injury severity.

Animals: 78 Thoroughbreds with (n = 38) and without (40) osteochondral injury.

Procedures: Serum and metacarpophalangeal or carpal joint SF samples were collected from noninjured horses before and at the end of 5 to 6 months of race training (pre- and postexercise samples, respectively) and from horses with osteochondral injury (1 joint assessed/horse).
