The impact of Helicobacter pylori (HP) on postoperative outcomes after sleeve gastrectomy (SG) is still controversial. A systematic review and meta-analysis were performed to compare the incidence of early complications after SG between HP-positive and HP-negative patients. Eight retrospective comparative studies were included, comprising 4,877 individuals. The prevalence of HP infection in gastric resected specimens ranged from 7.77 to 43.20%. There were no statistically significant differences between groups for overall complications (OR 1.46; 95%CI 0.95–2.23; p=0.08), bleeding (OR 1.35; 95%CI 0.70–2.60; p=0.38), and leak (OR 1.74; 95%CI 0.80–3.81; p=0.17) rates. The need for routine screening and treatment of HP infection before SG remains ambiguous.
