Follow-up group
Patient in this group undergo ESD for GIST, and regular follow-up are carried out for these patients on 72 ±3h,7±2d,14±2d,3 month,6 month,1 year,2 year,3 year,4 year,5 year after the treatment. The investigators record the success rate of operation,en bloc resection,operation time,complication rate,hospitalization days,hospitalization expenses,pathology results and tumor recurrence rate.
Patient in this group are given no intervention,the investigators record the tumor size and EUS features of the first endoscopic examination.Regular follow-up are carried out for these patients on 3 month,6 month,1 year,2 year,3 year,4 year,5 year after this check.Then,tumor size and EUS features of each time are collected accurately.
