What is Endoscopic Submucosal Dissection (ESD)?
☞ With endoscopic submucosal resection, cancerous polyps can be difficult to identify, may allow cancer to spread, and is associated with higher recurrence rates. Thus, total dissection is recommended. ESD is an advanced therapeutic endoscopic technique for the diagnosis and treatment of early stage colorectal cancer in early stage. In ESD, a solution is injected under the mucosal tissue causing the cancerous mucosal lesions to bulge out from the surrounding mucosal tissue so that they may be removed.
What is the difference between ESD and conventional polypectomy?
☞ A colon polypectomy is the removal of polyps using a polypectomy snare. In a polypectomy it is difficult to remove polyps greater than 2cm in diameter or in difficult locations because the use of snare over a large area has a significant risk of perforating the colon. It is also difficult to check whether the snare has been fully tightened cancerous tissue may not be fully removed when it is cut in pieces by the snare.
ESD is the most effective technique for the treatment of early stage colorectal cancer. It uses a special electrosurgical knife which enables entire polyps to be removed whole so that the uncertainties of polypectomy can be avoided. Additionally, it represents a quality of life improvement for patients who would otherwise require open abdominal surgery.
ESD in Daehang Hospital
☞ In May 2007, ESD, a endoscopic colorectal cancer therapy, was introduced at Daehang hospital. Daehang Hospital has now performed over 1,700 ESD procedures, the most in Korea. In April 2009, a 14 cm polyp was successfully removed from a patient. Daehang hospital has been recognized as the best colorectal clinic in Korea by both Korean and international societies.
