Removing 80% of the Stomach

The video tutorial explains the sleeve gastrectomy procedure, a common bariatric surgery that reduces stomach size to aid weight loss. It covers the anatomy of the stomach, pre-surgery requirements, and detailed surgical steps, including the use of laparoscopic incisions and a powered stapler. The effectiveness of the procedure is attributed to reduced ghrelin production and calorie intake. Potential complications like acid reflux and strictures are discussed, along with recovery expectations. The video concludes with reflections on the innovation of surgical techniques.
