Esophageal diseases are acute and causes weight loss, frequent vomiting are ongoing issues. It is preferable to offer these patients most precise diagnosis and to enable the proper treatment quickly to avoid serious consequences. This present study on “endoscopic Screening of esophageal disorders in clinical cases of dogs” was conducted at Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal, TamilNadu with the objective to screen the esophageal changes in the dogs with esophageal disorders with video-endoscope. Out of 7342 dogs, 42 dogs with symptoms suspicious of esophageal disorders were selected and subjected for detailed physical examination, and clinical examination. Out of 42 dogs, endoscopy was done in 12 dogs with esophageal disorders. Six apparently healthy animals brought for routine check up was studied for normal values of parameters under study. In this study, 0-3 years old dogs were highly affected with eso phageal disorders, the highest frequency of esophageal disorders was recorded in male dogs, Among the esophageal disorders, higher frequency of foreign bodies was recorded and retrieved in dogs followed by esophagitis, megaesophagus and tumour. Endoscope is the cutting edge instrument for the characterization of lesions involved in esophagitis by visualising and video recording of the observations is an inevitable tool for clinician for the evaluation of esophagus and post therapeutic review. Hence, for clinicians, endoscopy plays a versatile role in prompt treatment and prevention of consequences of esophageal disorders in dogs.
