Background
This study aimed to evaluate the effectiveness of modified Billroth – II (mB-II) with hinged anti-peristaltic afferent loop by comparing it with the Roux – en -Y (R-Y) method.

Methods
We retrospectively analyzed 344 patients with gastric cancer (GC) underwent distal gastrectomy (DG) between 2016 and 2021. The propensity-score matching (PSM) was conducted to balance baseline characteristics.

Results
We retrospectively analyzed 344 patients with gastric cancer (GC) underwent distal gastrectomy (DG) between 2016 and 2021. The propensity-score matching (PSM) was conducted to balance baseline characteristics.

Conclusion
There were no significant differences in functional outcomes between mB-II and R-Y reconstructions. The mB-II was superior to R-Y in operating time, hospital stays, and time to semi-solid diet tolerance. The mB-II could be considered an acceptable alternative reconstruction after DG.
