Dogs weighed 2.4-26 kg and cats 4.6-5.1 kg. Endoscopy was performed in dogs presented for vomiting in four cases, as well as diarrhea in 10 cases. All cats had large bowel diarrhea.

Six ileal, 5 cecal, and 4 colonic perforations were identified . Dogs were presented post endoscopy with inappetence in four cases, lethargy in four cases, abdominal pain in three cases, retching in two cases, and syncope in one case. All animals underwent surgical correction.

Histopathology did not identify lesions at the perforation site in any of the cases. Two dogs required a second surgery and one died 12 hours after surgery. Survival to discharge was 93%, with 78% surviving ≥8 months.
