Endoscopic Endocautery Polypectomy for the Treatment of Duodenal and Gastric Polyps in a Cat.

Endoscopic polypectomy is commonly performed in human medicine, with large-scale studies reported. However, few reports have described its use in veterinary medicine and, specifically, the procedure in the case of duodenal polyps in cats has not been reported. A 7 kg 14-year-old cat presented with recurrent vomiting for several months. Gastroduodenoscopy revealed a pedunculated polyp at the pyloric antrum and another in the duodenum, with its head protruding into the pylorus. Endoscopic polypectomy was performed using an electrosurgical snare with no recurrence of clinical signs after six months. Duodenal polypectomy in cats may be difficult because of space limitation but it can be safe, minimally invasive, and successful, thus avoiding more invasive surgical techniques. Endoscopic polypectomy may be a viable alternative to surgery in cats with gastric and duodenal polyps.
