Gastrointestinal endoscopy for small animals has evolved to become both an important diagnostic option and, in some situations even a therapeutic solution. Once considered to be only an adjunct to other diagnostic means, gastrointestinal endoscopy is now one of the most important techniques for evaluating patients with gastrointestinal signs. The minimal invasiveness, the increasing diagnostic capabilities, and the professional enjoyment in performing endoscopic procedures all add to the popularity of endoscopy in small animal practice. Endoscopy lends itself to a role of gastrointestinal evaluation because it provides visual documentation of the gastrointestinal lumen and the ability to collect samples for analysis, remove foreign bodies. Often other diagnostic test such as barium contrast studies or ultrasound evaluation of the gastrointestinal tract may not be sensitive enough to delineate many gastrointestinal mucosal disorders and fail to provide a means of collecting tissue for analysis. The gastrointestinal endoscopy has been performed for the first time in Petlife Hospital and the Veterinary Medicine Faculty of Tirana District in 12 dogs of different breeds, gender and age. All these dogs have exhibited clinical signs as anorexia, constipation, diarrhea, dysphagia, hematemesis, melena, mucoid feces, nausea, regurgitation, salivation tenesmus, vomiting and weight loss. Through gastric endoscopy was performed visual examination of the mucosal surface. The potential limitation of gastrointestinal endoscopy was the inability to diagnose submucosal lesions, gastrointestinal motility disorders or lesions that couldn’t be reached by endoscope. In 5 cases have been removed esophageal and gastric foreign bodies. In 2 adult dogs were identified the presence of gastric tumors. All the animals that have been examined through endoscopy were sedated with sedatives. As a conclusion the gastroscopy endoscopy remains in our days one of the most efficient diagnostic way of many surgical gastric pathologies.
