Endoscopic submucosal dissection (ESD) is used to remove selected early-stage
gastrointestinal cancers using endoscopic techniques.
It allows removal of lesions while preserving the surrounding organ.
What is ESD
ESD is a therapeutic endoscopic procedure used to remove superficial lesions
from the gastrointestinal tract.
It is applied in selected cases of early-stage cancer of the esophagus,
stomach, and colon.
The lesion is removed in one piece (en bloc resection),
allowing accurate pathological assessment.
When ESD may be considered
- Early-stage cancer limited to the mucosa or superficial submucosa
- No evidence of deep invasion or distant spread
- Lesions that can be accessed and treated endoscopically
- Cases where organ preservation is appropriate
Eligibility is determined based on endoscopic findings, imaging, and pathology.
How ESD is performed
The procedure is performed using specialized endoscopic instruments
to dissect the submucosal layer beneath the lesion and remove it.
Sedation may be used depending on the clinical situation.
Procedure time and length of stay vary depending on lesion size,
location, and patient condition.
After the procedure
Patients are monitored for complications such as bleeding or perforation.
Hospitalization is usually required.
Pathological assessment of the resected specimen determines
the need for further treatment or follow-up.
Appointment
Appointments are required in principle.
A referral letter from another medical institution is recommended but not mandatory.
