Abstract
Aim: To assess the usefulness of duodenoscopy in the diagnosis of duodenal ulcers in dogs. Materials and Methods: Sick dogs with chronic gastrointestinal problems were physically examined and samples were collected for haematology, biochemistry and faecal examination. Duodenal biopsies, duodenal contents and brush cytology were obtained via duodenoscopy. Results: Seven duodenal ulcers cases were recorded, higher incidences was recorded in Labrador retriever, 2-4 years of aged male dogs. Significantly decreased Hb (9.10 ± 0.25 g/dl), RBCs (4.39 ± 0.19 mill/cu.mm) and albumin (2.343b ± 0.13 g/dl) level were noticed. Hyperaemia with ulceration of duodenal mucosa was observed. Conclusion: Duodenoscopy is very much useful for detection of duodenal ulceration and provided a sensitive technique for early diagnosis of mucosal lesions and ulceration.
Highlights
A chronic small intestinal disorder of dog is the major contributor to canine gastrointestinal disorders
The majority of small intestinal disorders are occurring in the duodenum such as ulcer, inflammatory bowel disease (IBD) and small intestinal bacterial overgrowth (SIBO) [1]
Stress factors, neurological disease, entrogastric reflux, renal disease, hepatic disease, mucosal ischemia, primary gastroduodenal neoplasia, mastrocytoma and gastrinoma were associated with development of gastroduodenal ulceration and erosions [2]
Summary
A chronic small intestinal disorder of dog is the major contributor to canine gastrointestinal disorders. Duodenal ulcers are difficult to identify clinically because of the non-specific symptoms. They may or may not be identifiable through routine radiographic, ultrasonographic or laboratory evaluation methods, because many diseases of duodenum primarily involve the mucosal surface [3]. Endoscopic examination of the upper gastrointestinal tract has been used increasingly as a diagnostic tool in small animal practice. Use of this procedure has led to an early diagnosis of chronic gastrointestinal disease and better understanding of their pathophysiology [4]. Duodenoscopy is an efficient way of identifying the abnormalities of proximal small intestinal mucosa including mucosal irregularities, distortion, ulceration, neoplasia, inflammation and other mucosal disorders of the duodenum [5]. The aim of the study was to assess the usefulness of duodenoscopy in the diagnosis of duodenal ulcer in dogs
