Correlation Between the Number of Ghrelin-Secreting Cells in the Gastric Fundus and Excess Weight Loss after Sleeve Gastrectomy

Background Weight loss after laparoscopic sleeve gastrectomy (LSG) has been mainly attributed to the restriction of gastric volume; however; other factors may contribute to weight loss after LSG. This study aimed to investigate the correlation between the number of ghrelin-secreting cells in the gastric fundus and excess weight loss (EWL) at 12 months after LSG.
