sleeve gastrectomy
A restrictive bariatric procedure involving removal of approximately 80% of the stomach, creating a narrow gastric tube.
Full Definition
Sleeve gastrectomy, also known as vertical sleeve gastrectomy (VSG), involves the longitudinal resection of the stomach from the greater curvature, removing the fundus and body while preserving the antrum and pylorus. The procedure reduces stomach capacity to approximately 100-150ml and removes ghrelin-producing cells, contributing to appetite suppression. It is now the most commonly performed bariatric procedure worldwide due to its technical simplicity and excellent weight loss outcomes with lower complication rates compared to bypass procedures.
Usage
Usage note: Can be abbreviated as VSG in clinical contexts. The term 'gastric sleeve' is more patient-friendly.
