Safe, scar‑free removal of early GI tumors.
Advanced Endoscopic Submucosal Dissection (ESD)
What Is Endoscopic Submucosal Dissection (ESD)?
Endoscopic Submucosal Dissection (ESD) is a modern endoscopic technique used to remove early‑stage cancers and precancerous growths from the digestive tract. Unlike traditional surgery, ESD is performed entirely through an endoscope inserted via the mouth, leaving no external scars and allowing faster recovery.
This advanced procedure provides a curative, organ‑preserving alternative for many patients, reducing the need for major surgery.
Offers precise removal of early gastrointestinal tumors
Minimizes recovery time and improves quality of life
When Is ESD Done?
- For early esophageal cancer that has not spread deeply into the tissue layers.
- To treat early gastric (stomach) cancer and prevent the need for full surgical removal.
- For colon or rectal lesions that are too large for standard polypectomy but suitable for endoscopic removal.
- In precancerous conditions where abnormal tissue needs to be removed before it progresses.

What Happens During the Procedure?
Anesthesia for Comfort
The patient is kept sedated or under anesthesia to ensure a painless and safe experience.
Endoscope Insertion
An endoscope equipped with a camera and special instruments is gently inserted through the mouth into the digestive tract.
Submucosal Layer Creation
The doctor carefully lifts the lesion by injecting fluid underneath, creating a safe layer for dissection.
Precise Tumor Removal
The abnormal tissue is dissected and removed completely while preserving surrounding healthy tissue.
Curative, organ‑preserving treatment
ESD effectively removes early cancers while avoiding the need for invasive surgeries and preserving organ function.
Early Esophageal Cancer
Removes tumors confined to the inner lining of the esophagus, offering cure without invasive surgery.
Early Gastric Cancer
A preferred approach in Japan and increasingly worldwide for removing stomach tumors while preserving the organ.
Large or Complex Colon Polyps
Allows complete removal of polyps that are too big or flat for regular snare polypectomy.
Early Colorectal Cancer
Treats cancers limited to the mucosa or submucosa, helping patients avoid colectomy.
