[Experts consensus on proximal gastrectomy with jejunal interposition reconstruction (2025 version)].

In recent years, the proportion of early gastric cancer and proximal gastric cancer has risen, and function-preserving gastrectomy has received increasing attention. Proximal gastrectomy has also been highly valued. Reflux esophagitis is an issue that cannot be ignored in the reconstruction of the digestive tract after proximal gastrectomy. For this reason, a series of anti-reflux surgical methods have emerged and been applied in clinical practice. Jejunal interstitial reconstruction is one of the widely used anti-reflux surgical methods in clinical practice at present, but there is a lack of standardized guidance in terms of application indications and operation procedures. This consensus was formulated based on the latest evidence-based medical evidence and after multiple expert discussions, aiming to provide reference and guidance for clinicians in choosing proximal gastrectomy and jejunal interstitial reconstruction.
