Abstract
INTRODUCTION: Among the bariatric surgery procedures, laparoscopic sleeve gastrectomy (LSG) is one of the most common methods for effective and permanent weight loss among patients with severe obesity. Nonetheless, the LSG can be associated with long-term and short-term complications for the patient. The present study is aimed to investigate the effect of Helicobacter pylori on the complications of LSG, to answer the question of whether eradication of Helicobacter pylori in patients undergoing surgery can be effective in reducing postoperative complications. METHODS: In the present analytical-cross sectional study, which has been conducted in Shahid Bahonar Hospital in Kerman during 2018-2020, a total of 100 patients (including 38 males and 62 females) with an average age of 34.8 ± 2.4 years and an average BMI of 41.1 ± 3.1 underwent LSG surgery. After the operation, the gastric mucus specimens were taken from all patients for pathological examination of Helicobacter pylori infection. RESULTS: According to the results, 28 patients (28%) tested positive for Helicobacter pylori infection (HP positive), and 72 patients (72%) tested negative in this regard (HP negative). The results indicated no significant difference between the HP positive and HP negative patients in terms of demographic characteristics (age, gender, BMI). Overall, 11 patients (11%) exhibited postoperative complications of the LSG including 7 cases (7%) of the SSI, 2 cases (2%) of intraoperative bleeding, and 2 cases (2%) of leakage [No mortality was reported]. Out of the 11 patients with postoperative complications, 6 patients were HP positive including 4 cases of SSI, 1 case of bleeding, and 1 case of leakage. CONCLUSIONS: As indicated by the obtained results, the HP infection has seemingly no impact on the LSG postoperative complications. Nevertheless, it is necessary to conduct further studies on a larger number of patients with a longer follow-up time focusing on the effect of other parameters, such as BMI and underlying diseases.
