Abstract
The study aims to evaluate the changes between body mass index (BMI) and ghrelin levels after laparoscopic Nissen fundoplication (LNF). Twenty-four consecutive patients with gastroesophageal reflux disease who were scheduled for LNF consented to participate in the study. The participants' age, sex, preoperative (phase 0), postoperative 1st week (phase 1) and postoperative 4th week (phase 2) dysphagia scores, plasma ghrelin levels, and BMI were recorded. Compared to the preoperative level (phase 0), ghrelin was decreased in both phase 1 and phase 2. A strong correlation in the changes in the ghrelin values and BMI between phase 0 and phase 2 was detected. There was a strong, statistically significant difference in the changes in the BMI values between phase 1 and phase 2. Total plication of the fundus impairs its ghrelin-secreting functions for up to 4weeks and is accompanied by weight loss.
