Use of a Foley catheter to facilitate anal sac removal in the dog

Abstract

Chronic anal sac infection or impaction can be a frustrating problem for both the dog owner and veterinarian. Anal sacculectomy may be used to resolve clinical signs when medical management fails. Four dogs, ranging in size from 6 kg to 34 kg, were treated with closed anal sacculectomies, in which the balloon of a Foley catheter was used to facilitate surgical dissection of the sac. In all four cases, the Foley catheter successfully distended the anal sac during its removal. Clinical signs associated with the diseased anal sac were abated in the four dogs for a follow-up period of one-to-three years.
