PURPOSE: The aim was to compare the density of ghrelin-expressing cells (GECs) in morbid obese patients with or without intestinal metaplasia (IM).
MATERIALS AND METHODS: The study included 48 patients out of 244 who underwent laparoscopic sleeve gastrectomy between 2015 and 2019. IM was detected in the sleeve gastrectomy specimens of 24 of these 244 patients. The study group consisted of all of the patients with IM. It was a case matched study. Matching factors were age and gender. Ghrelin was stained with a Leica semiautomatic immunohistochemical-staining machine. Stained preparations with ghrelin were subjected to light microscopic examination.
RESULTS: The number of GECs in cases with IM was significantly lower than the cases without IM (p = 0.001). The number of GECs was significantly higher in cases with chronic inactive superficial gastritis than cases with chronic active superficial gastritis (p = 0.033).
CONCLUSION: We found that there was a decrease in the number of GECs in the corpus and fundus of the stomach in cases with gastric IM as a contribution to the literature. IM cause a decrease in the number of GECs in the gastric oxyntic glands. In addition, chronic active superficial gastritis is also associated with a decrease in the number of GECs. We can say that the common feature of all of these factors may be gastric mucosal damage. Consequently, damage to the gastric mucosa appears to reduce the number of GECs.
