Case Presentation at Endo-Skill Update 2011
case1A gastric depressed lesion
A shallow depressed lesion was shown in the greater curvature of the mid-gastric body. The demarcation of this lesion was unclear in white light. NBI magnified endoscopy showed irregular surface and vascular pattern. The demarcation was diagnosed clearly by NBI magnified endoscopy. How do you diagnose this lesion?
case2An esophageal depressed lesion
A reddish shallow depressed lesion was shown on the left wall of the middle esophagus. NBI endoscopy revealed a brownish area. NBI magnified endoscopy showed irregular micro vascular pattern. How do you diagnose this lesion?
case3A gastric depressed lesion.
A large shallow depressed lesion was found in the antrum. The color of the lesion wasn`t homogeneous, and the margin of the lesion was indistinct. NBI magnified endoscopy revealed irregular villous or unclear surface pattern. And irregular vascular pattern was observed in the unclear area. The size of the lesion is 2cm or more. Therefore, diagnosis of the histology is important to decide the treatment strategy. How do you diagnose this lesion?
case4A colonic flat elevated lesion.
A flat elevated lesion existed in the transverse colon. There was a shallow depressed area with mucosal contraction in the center part of the lesion. NBI magnified endoscopy revealed irregular surface and vascular pattern. How do you diagnose this lesion? Do you treat this lesion by EMR, ESD or Colectomy?
