Introduction: Obesity is a condition that has significant impact on public health. Recent exciting studies have linked chronic gastritis and H. pylori infection to obesity. Chronic gastritis has shown increased prevalence in obesity, more particularly H. pylori-related gastritis. This study aimed to determine the prevalence of chronic gastritis in morbidly obese patients who were subjected to sleeve gastrectomy, with focus on H. pylori-related gastritis. The aim was to demonstrate any influence on chronic gastritis of the surgical procedure or its post-operative course. 

Methods: One hundred six morbidly obese patients were subjected to vertical sleeve gastrectomy in King Abdulaziz University Hospital (KAUH) from March 2014 to April 2015. After full pre-operative preparation, sleeve gastrectomy was carried out, followed by histological examination of the specimen to view the chronic gastritis and H. pylori-related cases. All epidemiological data of the patients, including age, gender, body mass index (BMI), as well as mean operative time, length of hospital stay, and post-operative complications were documented and analyzed by IBM-SPSS version 22.

Results: Female patients presented the higher prevalence, i.e., 66% among the group of patients with sleeve resection, while 33% had chronic gastritis and 8.5% had H. pylori-related gastritis.

Conclusion: This study highlights the high prevalence of chronic gastritis in morbidly obese patients with reference to the high incidence of H. pylori-related gastritis among them, however no relationship was found between this infection and the post-operative outcome.
