Summary

This study tests a surgical technique for early stomach cancer that combines a camera in the abdomen (laparoscopy) with a flexible tube down the throat (endoscopy). Doctors inject a fluorescent dye near the tumor to highlight the first lymph nodes that might contain cancer. If those nodes are cancer-free, they remove only the tumor and a small part of the stomach, preserving more normal function. The goal is to see if this approach is safe and effective while reducing side effects compared to standard surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a combined laparoscopic and endoscopic surgical procedure using fluorescent dye (indocyanine green) to identify and remove sentinel lymph nodes and the primary tumor
What this could lead to
If successful, this approach could offer a less invasive, stomach-preserving surgical option for early stomach cancer patients, reducing long-term side effects.
What could go wrong
This is a small, single-center study with only 30 participants, so results may not apply broadly. The procedure's safety and effectiveness need confirmation in larger trials.
