Abstract
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. METHODS: The surface area of the gastric fundus was measured postoperatively in square centimeter. Histopathologic examination of the gastric fundus was made to estimate the number of ghrelin-secreting cells per square centimeter then was multiplied by the surface area of the fundus to calculate the total number of ghrelin-secreting cells in the fundus. The number of ghrelin-secreting cells was correlated with EWL and BMI at 12 months postoperatively. RESULTS: The present study included 39 patients of a mean age of 33.7 years. The mean %EWL at 12 months was 59.7 ± 12.7. The mean total number of ghrelin-producing cells in the gastric fundus was 26,228.4 ± 16,995.3. The total number of ghrelin-secreting cells had a weak positive correlation with BMI at 12 months (r = 0.2891, p = 0.07), and weak negative correlation with %EWL (r = - 0.1592, p = 0.33). CONCLUSION: There was a weak correlation between the total number of ghrelin-producing cells in the gastric fundus and plasma ghrelin levels with EWL after LSG.
