The Efficacy and Safety of Laparoscopic Proximal Gastrectomy With LPG-tbROSF Versus LTG for Localized Proximal Gastric Cancer.
120 participantsStarted 2026-01-01
Plain-language summary
This clinical trial is evaluating a new, function-preserving surgical technique for patients with early-stage cancer in the upper part of the stomach.
The current standard treatment is a Laparoscopic Total Gastrectomy (LTG), which involves the complete removal of the stomach. This study compares the standard LTG with an innovative procedure called Laparoscopic Proximal Gastrectomy combined with a novel anti-reflux reconstruction (LPG-tbROSF). This new technique removes only the cancerous upper portion of the stomach, aiming to preserve digestive functions and reduce post-surgery complications like acid reflux.
The main goal is to see if patients who receive the new, stomach-preserving surgery experience less body weight loss one year after the procedure compared to those who undergo the standard total gastrectomy. The research will also compare the two surgeries in terms of post-operative quality of life, nutritional status, acid reflux symptoms, safety, and long-term cancer outcomes.
The study is a multi-center, prospective, randomized controlled trial that plans to enroll 120 patients with localized cancer in the upper stomach.

✕. Severe respiratory diseases: severe impairment of lung function (FEV1%\<50%) or chronic respiratory failure;
✕. Severe liver and kidney dysfunction: ALT/AST \> 3 times the upper limit of normal, or eGFR \< 30 mL/min/1.73m²;
✕. patients complicated with other major chronic diseases, such as active tuberculosis, rheumatoid, systemic lupus erythematosus and other autoimmune diseases that affect surgical tolerance;

✕. Complicated with other upper gastrointestinal diseases, such as active gastric ulcer, pyloric obstruction, persistent bleeding, which seriously affect the operation;
