Gastric outflow surgical problems.

Gastric outlet disease in the dog and cat can be successfully managed by various surgical techniques. Diagnosis is based upon clinical history, radiographic, fluoroscopic and endoscopic studies, and histological examination of excised tissue. Procedures that can improve gastric outflow include pyloromyotomy, various pyloroplasties, and antrectomy with gastroduodenostomy or gastrojejunostomy. Complications are both perioperative and long-term. A successful outcome is dependent upon proper diagnosis, complete assessment of both related and concurrent disease states, proper selection of surgical procedure, careful surgical technique, and attention to postoperative and long-term complications.
