Gastroenterologists often follow up second look endoscopy after endoscopic submucosal dissection(ESD) of gastric neoplasms because they want to prevent bleeding of procedure sites. But Goto suggested in his retrospective analysis that a second-look endoscopy after endoscopic submucosal dissection for gastric epithelial neoplasm may be unnecessary. So, the investigators try to identify the hypothesis prospectively in this study.

Further study details as provided by Kosin University Gospel Hospital:

Primary Outcome Measures:
  • Post-ESD bleeding rate according to second look endoscopy [ Time Frame: Up to 60days ]

Secondary Outcome Measures:
  • bleeding complication rate according to location of lesion in stomach. [ Time Frame: Up to 60days ]
    Fundus, cardia, upper body, mid body, lower body, antrum anterior wall, posterior wall, great curvature, lesser curvature

  • Bleeding rate according to size of resected specimen [ Time Frame: Up to 60days ]
    longest diameter of specimen: millimeter

  • Post ESD bleeding rate according to total procedure time of endoscopic submucosal dissection [ Time Frame: Up to 60days ]
  • Post ESD bleeding rate according to bleeding degree during endoscopic submucosal dissection [ Time Frame: Up to 60days ]
    Mild: bleeding control time: <1/3 of total ESD procedure time. Moderate: bleeding control time: 1/3~1/2 of total ESD procedure time Severe: bleeding control time: >1/2 of total ESD procedure time

Estimated Enrollment: 268
Study Start Date: March 2013
Estimated Study Completion Date: March 2015
Estimated Primary Completion Date: March 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Second look endoscopy
This group is performed second look endoscopy about 24 hours later from endoscopic submucosal dissection.
Procedure: second look endoscopy
Second look endoscopy includes observation or prophylactic bleeding control of ESD site.
No Intervention: without second look endoscopy
This group is not performed second look endoscopy after ESD
