Laparoscopic sleeve gastrectomy is a procedure that permanently reduces stomach volume by surgically removing a portion of the stomach through small incisions made in the abdominal area. Endoscopic sleeve gastroplasty, on the other hand, is a procedure where the inner part of the stomach is reduced using special sutures, performed by entering through the mouth with a specialized endoscopic device. In this method, stomach tissue is not cut and removed; instead, the stomach wall is folded or constricted with sutures to reduce stomach volume. A special suturing device attached to the tip of the endoscope allows for safe and effective suturing inside the stomach.
