To describe an anal approach for excision of primary rectal tumors in dogs and to report outcome.Retrospective study.Dogs (n=23) with primary rectal tumors.Review of medical records (1990-2000) of dogs with primary rectal neoplasia excised surgically using an anal approach with rectal prolapse. With dogs anesthetized, the rectum was prolapsed, stabilized with stay sutures during tumor excision with 1 cm margins to the level of the muscularis, then the rectal mucosa was sutured.Each dog had only 1 tumor type (adenocarcinoma 8, solitary polyp 5, carcinoma 4, plasmacytoma 2, adenoma 1, leiomyoma 1, mucinous carcinoma 1, and papilloma 1). Mean tumor volume was 3.1 cm(3) (range 0.1-37.7 cm(3)). Postoperative complications (rectal bleeding 5, tenesmus 4) were mild and resolved within 7 days after surgery; another dog had partial mucosal dehiscence identified at 6 days. The primary tumor was incompletely excised in 1 dog (4.3%), and local recurrence occurred 16 and 24 months after surgery in 2 dogs. Outcome beyond the immediate postoperative period was known for 18 dogs, including 2 dogs still alive. Mean postoperative disease-free interval for these 18 dogs was 36.8 months (range 5-84 months).Surgical excision of tumors of the caudal rectum can be accomplished through the anus after rectal prolapse.An anal approach facilitated by rectal prolapse should be considered as a viable option for the surgical treatment of selected cases of tumors of the caudal aspect of the rectum in dogs.
