Tree-like Vessels on Magnifying Endoscopy

Magnifying image-enhanced endoscopy for collagenous colitis

Background and study aims  We report a case series of 5 patients with collagenous colitis (CC) presenting with chronic watery diarrhea, who were subjected to magnifying, chromoendoscopy and narrow band imaging (NBI). Magnifying chromoendoscopy revealed whitish-clouded, honeycomb-like appearance at orifices of the crypts. NBI with high magnification revealed irregular caliber variation of the su...

Magnifying endoscopy with narrow-band imaging for gastric heterotopic pancreas

Background and study aims  Heterotopic pancreas is a common subepithelial lesion in the stomach. However, its histological diagnosis is difficult when tissue samples are obtained with a conventional biopsy forceps. This study aimed to describe the magnifying endoscopy with narrow-band imaging (ME-NBI) features of gastric heterotopic pancreas. Patients and methods  We retrospectively analyzed ...

Magnifying Endoscopy and Chromoendoscopy in Upper Gastrointestinal Tract: Clinical Applications

Clinical usefulness of magnifying endoscopy for non-ampullary duodenal tumors

Study aims This study aimed to investigate the clinical usefulness of magnifying endoscopy (ME) for non-ampullary duodenal tumors. Patients and methods We enrolled 103 consecutive patients with non-ampullary duodenal tumors that were observed by ME with narrow-band imaging (ME-NBI) and had pit pattern analysis before endoscopic resection at Hiroshima University Hospital before December 2014. ME...

Surveillance by Magnifying Endoscopy in Patients with Ulcerative Colitis

Background: Patients with total or left-sided ulcerative colitis (UC) for more than 10 years have an increased risk of colon cancer. We studied usefulness of magnifying chromoendoscopy for the surveillance of dysplasia and colitic cancer associated with UC. Methods: From April 2003 through February 2004, 39 patients who had total or left-sided UC for at least 7 years were prospectively enrolled...
