diagnosis

Endosonographic image of a duodenal diverticulum using watre filling

diagnosis

Small pedunculated sigmoid adenoma (low grade); the distorted pattern at the polyp tip does not indicate more severe histopathology

diagnosis

Close-up image of a Barrett carcinoma on NBI only visible with a cap

diagnosis

Endosonographic visualization of a distal bile duct carcinoma with echopoor and irregular wall thickening and a small part of the bile duct lumen

diagnosis

See image of last week – visualization with cap and acetic acid staining – typical Barrett epithelium

diagnosis

Image of the cardia with questionable small Barrett island – see image next week

diagnosis

Reddish fundic gland polyp in the stomach (histologically confirmed)

diagnosis

Slightly prominent appendiceal orifice in cecum

diagnosis

Distal esophagus in a patient with longstanding achalasia showing erosive changes, probably due to stasis

diagnosis

Valley Sign of a colon adenoma, first described by Dr. Rex in 2017

diagnosis

Tubullovillous adenoma.

diagnosis

BLI highlights the mucosal surface and vascular pattern morphology. In combination with an optical zoom, in vivo diagnosis of a tubular adenoma can be easily achieved

diagnosis

Carcinoma in a short-segment Barrett’s esophagus

diagnosis

Submucosal tunnel during a POEM procedure.

diagnosis

Post-inflammatory polyps in ulcerative colitis imaged with LCI. Identification of dysplasia in those cases can become extremely challenging.

diagnosis

NET of the rectum imaged with BLI. Although small, the lesion can be clearly demarked for subsequent endoscopic resection.

diagnosis

Invasive amebiasis in the colon, with ulcerations in the right colon.

diagnosis

Multiple vessels after polypectomy. Not that endoscopic clipping is not always necessary.

diagnosis

Mucomyotomy of Zenker’s diverticulum. Muscle fibers are already clearly exposed.

diagnosis

Gastric cancer imaged with BLI for visualization of the mucosal surface and vascular pattern network. Endoscopic resection (ESD) was performed for the lesions.

diagnosis

Long segment Barrett’s esophagus imaged with LCI.

diagnosis

Small early gastric cancer visualized with LCI. The so called “red-in-purple” sign is always suspicious for neoplasia.

diagnosis

Inflammatory colon polyps are common. As identification of dysplasia in those lesions is difficult, endoscopic resection should be performed.

diagnosis

BLI highlights the mucosal surface and vascular pattern morphology. In combination with an optical zoom of 135-fold, optical diagnosis of a tubular adenoma can be easily achieved.

diagnosis

Endoscopic full thickness resection with the FTRD system. Duplication of the single layers is clearly visible.

diagnosis

Barrett’s cancer imaged with Linked Color Imaging (LCI) which strongly highlights the neoplastic tissue.

diagnosis

Large duodenal lipoma

diagnosis

Submucosal bulge in the esophagus, collapsing (right) suggesting esophageal duclication. Confirmation by endosonography showing mucosal structure in the wall of the duplication (below).

diagnosis

Duodenum in Graft versus Host Disease (GvHD)

diagnosis

Food residues in a smaller Zenker diverticulum

diagnosis

Duodenal varices

diagnosis

Recurrent Zenker diverticulum, scarring and deviating

diagnosis

Healed duodenal ulcer without fibrin

diagnosis

Small Zenker diverticulum (1 cm on barium swallow), hardly visible on endoscopy beside a hypertrophic upper sphincter

diagnosis

Healing duodenal ulcer with elevated margin at the upper duodenal curve

diagnosis

Linitis plastica (diffusely infltrating gastric cancer)

diagnosis

Duodenal bulb ulcer

diagnosis

Epiphrenic diverticulum in the distal esophagus

diagnosis

Early gastric cancer at the angular fold (incisura angularis)

diagnosis

Patient with a known ulcerative colitis and elevated liver enzyms - ERCP with typical aspect of a PSC

diagnosis

Barrett esophagus after forceps biopsies, simulating erosions or neoplasia

diagnosis

Patient with a large common bile duct stone

diagnosis

Duodenal diverticulum

diagnosis

Flat erosive Barrett cancer (AEG cancer type I, AEG=adenocarcinoma of esophagogastric junction)

diagnosis

Classic long-segment Barrett esophagus

diagnosis

Capsule endoscopy in a patient with "Blue rubber bleb naevus Syndrom", showing a venous ectasia in the jejunum

diagnosis

Two angiodysplastic lesions at the gastric incisura (angular fold)

diagnosis

Patient with a pseudomembranous colitis (Clostridium difficile)

diagnosis

Barrett esophagus with prominent vessels in a patient with portal hypertension

diagnosis

Multifocal areas of intestinal metaplasia (NBI imaging)

diagnosis

Small flat duodenal adenoma in the descending duodenum

diagnosis

Patient with Crohn's disease and fistulation from sigmoid colon to descending colon

diagnosis

Known Barrett esophagus with 2 small neoplastic lesions, on histology metastases of breast cancer

diagnosis

Fibrinous gastric erosions (NSAID)

diagnosis

Flat duodenal adenoma at the distal end of the bulb

diagnosis

Barrett mucosa in near focus and with acetic acid staining with central high-grade dysplastic lesion

diagnosis

Pedunculated ampullary adenoma

diagnosis

Polypoid gastric erosions

diagnosis

Esophagus in advanced achalasia showing chronically inflamed and thickened mucosa and a distal ulcer due to pressure necrosis by obstructing food

diagnosis

Hämorrhagic gastric erosions

diagnosis

Duodenal involvement in Crohn´s disease

diagnosis

Esophagus in achalasia showing muscular rings and prominent veins

diagnosis

diagnosis

Gastric erosion with biopsy positive for cancer, but ESD specimen negative („biopsy cancer“)

diagnosis

Duodenal bulb with gastric metaplasia (magnification endoscopy)

diagnosis

Distal esophagus in achalasia; muscular spasm leads to overvisualization of submucosal vessels
