Objective:
To report a modified colostomy technique for permanent fecal diversion in calves with colonic atresia.
Study Design:
Prospective study.
Animals:
Calves (n=19) with colonic atresia.
Methods:
Clinical findings, white blood cell counts, radiologic, ultrasonographic, and intraoperative findings were recorded. Calves were randomly divided into 2 groups: group 1 (n=9) had conventional colostomy and group 2 (n=10) had a modified colostomy. Technique efficacy was evaluated by postoperative observation, owner satisfaction, and calf survival.
Results:
Fifteen (79%) calves were discharged from the hospital; 4 (21%) group 1 calves died within 24 hours after surgery. Two (40%) group 1 calves died 18 and 30 days after surgery and 5 (50%) group 2 calves died 2-60 days after surgery. Eight calves reached slaughter weight (120+/-10 kg); 5 group 2 calves grew normally but the 3 group 1 calves had lower weight gain. Owners of the calves with conventional colostomy reported that the evacuation of feces was continuous whereas owners of calves with the modified colostomy reported that feces were released through the stoma in intervals.
Conclusion:
Modification of conventional colostomy by forming an hourglass shaped stoma lessens fecal incontinence but there was no difference in survival rate.
Clinical Relevance:
Modified colostomy was considered advantageous because of intermittent fecal discharge from the stoma compared with continuous fecal release in conventional colostomy. The modified technique seemingly has a beneficial effect on growth of the calf.
