case1Gastric ulcerative lesion.

A shallow ulcer was noted in the lesser curve of antrum. The shape was slightly irregular. However, no IIc area was shown around the ulcer by indigo carmine spray. A magnified endoscopy with NBI system showed slightly irregular surface pattern in the posterior side of the ulcer. How do you diagnose this lesion?

No.1
No.2
No.3
No.4

case2Gastric depressed lesion.

A well demarcated shallow depressed lesion was shown in the cardia. The shape was irregular and the color was red. NBI magnified endoscopy showed irregular micro vascular pattern. It is a most difficult potion to perform ESD. How will you diagnose and treat this lesion?

No.1
No.2
No.3
No.4

case3Esophageal depressed lesion.

A shallow depressed lesion was noted in the middle esophagus. NBI endoscopy revealed a brownish area. NBI magnified endoscopy showed irregular micro vascular pattern. How do you diagnose this lesion?

No.1
No.2
No.3
No.4

case4Esophageal protuberant lesion.

A flat reddish lesion was noted in the middle esophagus. The center part of the lesion showed SMT like protrusion. NBI magnified endoscopy revealed irregular micro vascular pattern. IDUS showed iso-hypo echoic mass. The key point of diagnosis is invasion depth. How do you diagnose this lesion?

No.1
No.2
No.3
No.4

case5Rectal flat protuberant lesion

A flat white protuberant lesion was noted in the rectum. Magnified endoscopy with indigo carmine spray showed atypical pit pattern, and that with NBI showed atypical surface and vascular pattern. How do you diagnose this lesion?

No.1
No.2
No.3
No.4

case6Colonic double flat protuberant lesions

A flat protuberant lesion was noted in the transverse colon. The surface was slightly irregular by indigo carmine spray. A protuberant lesion with central depression was noted in the sigmoid colon. NBI magnified endoscopy revealed irregular surface pattern. How do you diagnose those lesions? Can to treat endoscopically?
