Gastric Case 6

Dr. Khanh Do-Cong Pham, FASGE, FESGE

Department of Medicine

Haukeland University Hospital

Bergen, Norway

Procedure Information


Scope: GIF-EZ1500

Case: Two gastric neuroendocrine tumors (NET)

Organ: Stomach

Patient Information: F, 84, Two gastric NETs

Medical History: Hypertention, cardial insuficiency, asthma

1. 1st Gastric NET (WLI)​

#WLI

The tumor appears light yellowish and slightly elevated.

2. 1st Gastric NET (WLI)​

#WLI

Using the cap for tactile impression, the tumor is firmer than the surroundings.

3. 1st Gastric NET (WLI, Near Focus, Under water)​

#WLI Under water Near Focus

The Near Focus allow close up evaluation. The tumor can be seen beneath of the thinner part of the mucosa.

4. 1st Gastric NET (NBI)

#NBI

The 1st Gastric NET in NBI.

#NBI Under water Near Focus

The 1st Gastric NET in NBI close-up. The tumor is more apparent where the mucosa is thin.

6. 1st Gastric NET (TXI mode 1)

#TXI mode 1

The TXI mode enhance the color difference.

7. 2nd Gastric NET (WLI)

#WLI

Slight elevation, with central thinning of the mucosal surface

#NBI Under water Near Focus

The 2nd Gastric NET in near focus and NBI

#NBI Under water Near Focus

The 2nd Gastric NET in near focus and NBI

#WLI Near Focus Acetic acid Underwater

Acetic acid 2-3% was applied to enhance the mucosal surface. There is intestinal metaplasia surrounding the tumor.

#WLI Near Focus Acetic acid Underwater

Acetic acid 2-3% was applied to enhance the mucosal surface. There is intestinal metaplasia surrounding the tumor.

#WLI Near Focus Acetic acid Underwater

Acetic acid 2-3% was applied to enhance the mucosal surface. There is intestinal metaplasia surrounding the tumor.

#NBI Near Focus Acetic acid Underwater

Combining NBI, Near Focus, and acetic acid enhances the surface structures in detail.

#NBI Near Focus Acetic acid Underwater

Combining NBI, Near Focus, and acetic acid enhances the surface structures in detail.

#NBI Near Focus Acetic acid Underwater

Combining NBI, Near Focus, and acetic acid enhances the surface structures in detail.

We demonstrate in the video how gastric neuroendocrine tumors may look like with the different properties of the EVIS X1 and the GIF-EZ1500 gastroscope.

Overall Comment

Most gastric neuroendocrine tumors (NETs) are associated with chronic atrophic gastritis and can be identified through high-definition white light endoscopy. NETs typically appear as small round “hills” in a flat landscape (Paris Is or Is+IIc). The mucosa on the surface tends to be thin for larger lesions, and the tumor presents as a subepithelial mass with a yellowish hue. Narrow Band Imaging (NBI) and TXI can be used for easier recognition of gastric NETs.
