Based on the Chinese expert consensus (2024 Edition): recent advances in digestive tract reconstruction after proximal gastrectomy

Abstract Proximal gastrectomy (PG) is an important surgical approach for the treatment of adenocarcinoma of the esophagogastric junction (AEG), and the choice of digestive tract reconstruction method has long been a key focus in clinical practice. In 2020, a Chinese expert panel released the "Chinese consensus on digestive tract reconstruction after proximal gastrectomy (2020 Edition)," providing guidance for clinical practice in digestive tract reconstruction after PG. However, as anti-reflux digestive tract reconstruction techniques continue to evolve, various surgical procedures have been innovated, refined, and optimized. To update and promote the latest research findings and perspectives in this field, the Chinese expert panel released the "Chinese expert consensus on digestive tract reconstruction after proximal gastrectomy (2024 Edition)" in 2024. This consensus, based on recent clinical study evidence, provides a comprehensive overview of the definition and indications for PG, the technical essentials and the anti-reflux efficacy of various digestive tract reconstruction procedures. It also proposes the establishment of a scientific evaluation system to assess anti-reflux effects. This review will summarize and interpret the recommendations outlined in the consensus, and simultaneously elaborate on the latest research progress in this field based on this consensus.
