Complications will be evaluated by waiting 30 seconds after firing 30 seconds during stapler compression while performing sleeve gastrectomy.

Those with a BMI between 35.0 and 39.90 and those with an obesity-related comorbidity, and all morbid obesity patients with a BMI of 40.0 and above, were previously adequate for at least 6 (six) months with non-surgical (diet, medication, exercise, etc.) methods. Patients with morbid obesity who could not lose weight and who were unsuccessful will be included in the study by signing an informed consent form for the operation and study, after being evaluated by the "obesity council" consisting of endocrinology, psychiatry, anesthesiology, dietitian and general surgery, and approved for bariatric surgery. Waiting will be made for patients whose patient file number has an odd number in the last digit, and no waiting will be made for patients whose last digit is an even number. At the time of the operation, the patients will be put on thromboembolic stockings and the reverse trendelenburg position will be given and the operation will be started with the laparoscopic method. After the stomach is mobilized from the adjacent organs and structures, the 38F gastric tube will be advanced to the stomach, the tissue will be closed with a 60 mm laparoscopic stapler, waited for 30 seconds, and then ignition will be performed. After the stapler is fired, a waiting period of 30 seconds will be waited and it will be removed from the tissue. In this first case, whether there is bleeding or not, at how many points, whether additional intervention is required or not will be recorded. At the end of the operation, the gastric tube will be withdrawn, and the stomach will be filled with 120 cc saline colored with methylene blue to check if there is any leakage. If there is no leakage, a gastric drainage drain will be placed and the operation will be completed. Postoperative 24 - 48 . After discharge, the patient will be called for routine control on the 1st week, 15th day and 30th day after discharge.
