Total gastrectomy is applied to treat patients with malignant gastric tumors and it has a lot of postprandial symptom such as dysphagia, pyrosis, lack of appetite, and reduced food intake, followed by loss of body weight. Minimally invasive surgery has numerous advantages that makes it a valuable method in various operations. Laparoscopic gastric surgery is a new and technically challenging surgical procedure that can be done with safety and potential benefit, particularly in decreased wound-related complication. This experimental study was done in 10 adult male dogs in two groups (5 dogs in each group). Subtotal gastrectomy was applied with laparoscopic assisted and laparotomy method, respectively. Reconstruction was done with standard Roux-en-Y method in both groups. Clinical signs and body weight were recorded until 30 days after surgery. On day 30th after operation, simple and contrast radiographs was taken in all patients to evaluate the emptying time. There was no difference between the rates of emptying time in two groups. Esophagoscopy and gastroscopy with flexible endoscope was performed in all patients of both groups to observe morphology of the esophagus and remained part of stomach, status of entreogastric biliary reflux and presence of esophagitis reflux. Reflux esoghagitis was not seen in any patient in both groups. The rate of bleeding and the time of surgery were more in laparotomy and less in laparoscopy method. The exploratory laparoscopy performed on day ...
