2 Cases of Rectal Diverticulum in Dog

Abstract

Rectal diverticulum is a condition in which the rectal mucosa and submucosal layer protrude in a sac shape into the muscular dehiscence of the rectum due to the fragility and tearing of the muscular layer of the rectum wall. Solitary rectal diverticulum is a rare condition in dogs and most case were reported concurrent with perineal hernia. In this study, we reported two cases of rectal diverticulum alone without concomitant perineal hernia. In these 2 cases, rectal diverticulum occurred below the second coccygeal vertebra and no abnormalities were observed in peritoneal and pelvic diaphragm.
