Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Endoscopic submucosal dissection (ESD) is an advanced technique of therapeutic endoscopy for superficial gastrointestinal neoplasms. Three steps characterize it:injecting fluid (several fluids such as saline, glycerol and hyaluronic acid are usually combined with diluted epinephrine) into the submucosa to elevate the lesion,cutting the surrounding mucosa of the lesion, and dissecting the submucosa beneath the lesion.
The amout of fluid varies according to the size of cancer and the amount is appropriate when the fluid injected can make the cancer safe enough for endoscopists to cut it off.
This is a one-off treatment and the duration of ESD itself often varies from one hour to 3 hours.

Comparator / control treatment
Surgery treatment for early esophageal cancer is actually esophagectomy.
Esophagectomy is the removal of a segment of the esophagus; as this shortens the length of the remaining esophagus, some other segment of the digestive tract (typically the stomach or part of the colon) is pulled up to the chest cavity and interposed.
This is a one-off treatment and the duration of esopagectomy itself often varies from 2 hours to 3 hours.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Each patient enrolled in the study will be given a serial number and will be randomized in blocks to one of the two groups:ESD and surgery. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?
