Abstract
Chronic constipation, nonresponsive to medical management and associated with idiopathic megacolon, was diagnosed in 38 cats from 1979 to 1985. All cats were treated by subtotal colectomy and enterocolostomy, in which the ileum or distal portion of the jejunum was joined to a 2- to 4-cm segment of distal portion of the colon preserved to accommodate an end-to-end anastomosis. After surgery, cats usually were depressed and anorectic, had tenesmus, and passed liquid tarry feces. In 37 cats 1 week to 3 months after surgery, character of the feces changed from diarrhea to soft semiformed or formed feces. One cat had severe diarrhea that was nonresponsive to diet change and pharmacologic treatment; the diarrhea resolved after 4.5 months. One cat developed a stricture of the enterocolostomy, which was relieved by 3 balloon catheter dilatations. All cats regained normal appetite, did not lose weight, and were not incontinent. Three cats had sporadic episodes of constipation and were easily treated. Results of histologic examination of the resected portion of colon in 23 cats were inconclusive.
