Severe post-GDV gastroparesis managed with sleeve-type gastrectomy in a dog.

Sleeve gastrectomy is a salvage option for post-GDV gastroparesis refractory to medical therapy.

This case report documents a Belgian Malinois that developed severe post-operative gastroparesis following surgical correction of gastric dilatation-volvulus (GDV). The dog presented with recurrent gastric distension, vomiting of undigested food, and progressive weight loss refractory to medical management with prokinetic agents. Diagnostic imaging and endoscopy revealed a markedly enlarged, atonic stomach with patent pylorus. Exploratory laparotomy confirmed global gastric atony, and sleeve-type gastrectomy was performed as a salvage procedure. Histopathological examination identified interstitial fibrosis and sparse nerve plexuses, suggesting truncal vagal injury as the underlying etiology. Despite persistent delayed gastric emptying on post-operative barium studies, the dog achieved clinical improvement with weight gain, tolerance of liquid meals, and absence of vomiting or dilatation at 12-month follow-up. The authors propose that severe gastroparesis can develop as a delayed complication of GDV and that sleeve gastrectomy may represent a viable surgical option for medically refractory, end-stage gastric atony in dogs.
