Gastric perforation secondary to incarcerated para- esophageal hiatal hernia in a French bulldog

A 6-month-old, intact female, French bulldog was presented to the Emergency Department for evaluation of vomiting and diarrhea over the preceding week which had not responded to supportive medical therapy. Imaging studies identified an incarcerated para-esophageal hernia with peritoneal effusion and gas consistent with gastrointestinal perforation. Following stabilization, the dog underwent an exploratory laparotomy which confirmed an incarcerated hiatal hernia and gastric perforation. A gastrectomy was performed to repair the defect, and to prevent recurrence both a herniorrhaphy and esophagopexy were performed. Post-operative care required treatment for septic shock including vasopressor and hydrocortisone infusions and plasma transfusions for colloidal support. The patient was successfully discharged 4 days after surgery. The histopathology results identified spiral bacteria consistent with Helicobacter spp. which was subsequently treated with oral antibiotics and a proton pump inhibitor. The dog has had no further gastrointestinal signs in the 90 days since surgery. Gastric perforation and peritonitis can occur secondary to an incarcerated esophageal hiatal hernia, and if treated promptly can result in a successful outcome. This case demonstrates a novel etiology of gastric perforation which may be associated with brachycephalic breeds.
