Spectrum of gastric histopathologies in morbidly obese Turkish patients undergoing laparoscopic sleeve gastrectomy.

OBJECTIVE: In this study, we aimed to describe the findings associated with gastric pathology and to identify the prevalence of Helicobacter pylori (H. pylori) in patients undergoing laparoscopic sleeve gastrectomy (LSG).

PATIENTS AND METHODS: Gastric specimens of a total of 291 patients (225 females, 66 males; mean age: 42 years; range: 18 to 60 years) who underwent LSG for the treatment of morbid obesity were analyzed. Histopathologic diagnoses and their relation with body mass index (BMI), age and gender were evaluated.

RESULTS: In the histopathological examination of sleeve specimens, 58 patients (19.93%) had chronic gastritis, 102 patients (35.05%) had chronic active gastritis, 27 patients (9.27%) had follicular gastritis, 47 patients (16.15%) had active follicular gastritis, one patient (0.34%) had a glomus tumor, and one patient (0.34%) had a gastrointestinal stromal tumor. The gastric mucosa was normal in 55 patients (18.90%). Intestinal metaplasia was detected in eight patients (2.74%). The H. pylori test result was positive in 126 patients (43.29%). There was no statistically significant difference between the pathological diagnoses and age and sex of the patient.

CONCLUSIONS: Our study results suggest that the prevalence of chronic active gastritis and H. pylori positivity is high in morbidly obese Turkish patient population. No significant difference was found between the pathological diagnosis in obese patients with LSG operation in terms of age and sex.
