Core Tip	The early postoperative course of Helicobacter pylori (H. pylori) following distal gastrectomy remains poorly characterized. Using a standardized stool antigen test protocol, this study demonstrated that spontaneous H. pylori clearance occurs in approximately three-quarters of patients within 3 months after surgery. Among evaluated clinicopathological variables, a higher preoperative American Society of Anesthesiologists score was associated with spontaneous clearance, suggesting that host-related factors may influence early postoperative H. pylori dynamics. These findings provide clinically relevant insights that may help optimize postoperative surveillance strategies and inform the timing of eradication therapy after distal gastrectomy.
