Background: Weight loss after laparoscopic sleeve gastrectomy (LSG) is usually attributed to the volume restrictive effect of the procedure in addition to specific hormonal changes. Objective: The present study aimed to investigate the changes in plasma ghrelin levels, the number of ghrelin producing cells and histopathological changes in the remaining pouch after LSG. Methods: The present study included 27 patients with morbid obesity. The plasma ghrelin levels were measured before and six months after LSG and the change in their levels was assessed in relation to body mass index (BMI) after LSG. Immunohistochemical staining of cellular ghrelin was used to evaluate the number and distribution of ghrelin producing cells in the resected specimen and the mucosal changes in the remaining gastric pouch after LSG were assessed at 6 months postoperatively. Results: The mean age of patients was 33.9± 21.9 years. At six months after LSG, BMI decreased from 52.6± 12.8 to 40.8± 7.2 Kg/m2 (p= 0.0001). The plasma ghrelin level decreased significantly from 564.1± 15 to 434.7± 22.6 at six months after LSG. There was strong positive correlation between BMI after LSG and plasma ghrelin level (R= 0.906, p= <0.0001). A significant improvement in the inflammatory parameters was noticed by histopathologic examination. The mean ghrelin positive cell per specimen decreased significantly from 25.37± 3.5 to 13.7 ± 2.12. Conclusion: There was good positive correlation between weight loss and lowering of plasma ghrelin level, also complete removal of the fundus was associated with more weight loss.
