Two stage surgical management of Gastric Dilatation and Volvulus in dogs.

摘要

A male Great Dane, 4 years old and 45 kg, is reported with history of unproductive retching. The dog showed distended abdomen and respiratory distress. The capillary refill time was 2.5 seconds. Clinical examination revealed tympanic sound at the epigastric region and an obviously distended stomach. The second case was a German Shepherd, 6 years old and 24 kg. The mucous membrane was brick red and the capillary refill time was 3.5 seconds. The abdomen was severely distended and had marked splenic enlargement which was palpable on the ventral abdomen. Ventrodorsal survey radiograph revealed compartmentalization of the stomach distended with gas and a displaced pylorus indicating the presence of volvulus. Both the conditions were diagnosed as gastric dilatation and volvulus and the dogs were prepared for temporary decompression. The linea alba was incised and the omentum was visualized over the severely distended and congested stomach suggestive of gastric volvulus. Generalized congestion of the stomach was observed in the Great Dane. A small portion of the stomach appeared grayish in the German Shepherd. A stab incision was made on the stomach and gas was slowly relieved. After temporary gastrostomy, the animals were kept under continuous fluid infusion at 15 ml/kg. At 6 h following temporary decompression, both dogs showed an improved cardiovascular status with a CRT of <2 sec. Both dogs had permanent gastropexy. The gastric wall of the Great Dane appeared viable and the gastrotomy incision was closed with PDS 1/0 using Connell's suture pattern. In the German Shepherd, a portion of the gastric wall was necrotic and partial gastrectomy was performed. The wound edges were closed with PDS 1/0 using Connell's suture pattern. Both animals recovered well and the sutures were removed 12 days after surgery.
