Prospective randomized controlled trial compares tunnel anastomosis and double tract reconstruction for reflux esophagitis.

Tunnel anastomosis appears to reduce reflux esophagitis compared to double tract jejunal interposition, improving patient outcomes.
The study aims to evaluate 240 patients, with each group containing 120 participants for effective comparison.
A multicenter, prospective, randomized controlled trial design will ensure robust data collection over 12 months.
Significant insights into digestive reconstruction methods may emerge, helping improve surgical standards for proximal gastrectomy.

Li et al. (2025) studied this question.
