Obesity is an epidemic disease, and its prevalence is predicted to rise in the future. Many health and social comorbidities, such as cardiovascular disease, type 2 diabetes mellitus, cancer, nonalcoholic fatty liver disease, arthritis, infertility, eating disorders, unemployment, and low quality of life, have been associated with obesity.

An increasing body of literature demonstrates significant remission of obesity-related comorbidities and an increase in life expectancy after surgical treatmentComputed tomography (CT) volumetry, a recent and non-invasive method that measures volume of internal organs, was used to assess the gastric pouch volume one month and six months following laparoscopic sleeve gatrectomy in addition to performing virtual gastroscopy to assess any anatomical abnormalities in the pouch. We compared the gastric pouch volume after one and six months and observed the relation of the volume changes with the patients' weight loss.
