Mesenteric Vascular Preconditioning Combined With Laparoscopic and Endoscopic Cooperative Surgery for Submucosal Tumor at the Gastroesophageal Junction
Sponsor: Peking University People's Hospital
Summary
This study is a single-center, prospective, single-arm, exploratory clinical study (phase II exploratory trial). No parallel control group was established in the study, and all subjects who met the inclusion criteria underwent a uniform surgical treatment approach, namely, double-scope combined resection with mesenteric vascular preconditioning. The study aims to preliminarily evaluate the safety and effectiveness of this novel surgical strategy for the treatment of submucosal tumor at the gastroesophageal junction, and to provide data support for subsequent larger-scale controlled studies.
