Procedure Information


Scope:GIF-EZ1500

Case: Esophageal papilloma

Organ: Esophagus

Patient information: F, 67

Medical history: Heartburn

1. WLI

#WLI #A7 structure enhancement #Auto Iris

A very small reddish area at 9 o’clock appears suspicious.

2. TXI™ technology ​

#TXI technology Mode 1 #B7 structure Enhancement #Auto Iris

Using TXI™ technology increases the color contrast, meaning the reddish area is becoming more prominent1.

3. NBI™ technology

#NBI technology #NBI technology Color Mode 1 #B7 structure Enhancement #Auto Iris

NBI™ technology reveals a small brownish area.

4. Near focus with NBI™ technology

#NBI technology #NBI technology Color Mode 1 #B7 Structure Enhancement #Auto Iris

Enlarged IPCLs with brownish background mucosa can be seen.

5. WLI

#WLI #A7 structure enhancement #Auto Iris

In the middle esophagus, further papillomas can be easily identified by WLI.

6. TXI™ technology

#TXI technology Mode 1 #A7 structure enhancement #Auto Iris

TXI™ technology is enhancing the distinct texture component of these lesions1.

7. NBI™ technology

#NBI technology #NBI technology Color Mode 1 #B7 Structure Enhancement #Auto Iris

NBI™ technology demonstrates no pathological IPCLs.

8. WLI

#WLI #A7 structure enhancement #Auto Iris

In the lower esophagus, multiple papillomas can be identified.

9. TXI™ technology

#TXI technology Mode 1 #A7 structure enhancement #Auto Iris

Under TXI™ technology the inflammatory aspect is enhanced by increased color contrast1.

10. NBI™ technology

#NBI technology #NBI technology Color Mode 1 #B7 structure Enhancement #Auto Iris

Inflammatory changes around the papilloma can be seen by dilatated IPCLs.

11. Near focus with NBI™ technology

#NBI technology #NBI technology Color Mode 1 #B7 structure Enhancement #Auto Iris

There are additional subtle lesions with IPCL dilatations.

12. Lugol staining and TXI™ technology

#TXI technology Mode 1 + lugol staining #A7 structure enhancement #Auto Iris

Lugol staining and TXI ™ technology shows no typical Lugol voiding behavior.
