Laparoscopic Sleeve Gastrectomy (LSG) has recently evolved as standalone procedure for morbid obesity. LSG works by reducing the size of the stomach to create satiety with small amount of food intake as it cannot accommodate a larger meal. Small intragastric volume leads to decreased food consumption and earlier distension of the stomach which causes firing of stretch receptors leading to perception of satiety. Other mechanisms include decreased level of ghrelin due to resection of gastric fundus which is the main site of ghrelin production
Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review
