Current TNE scopes are NOT….

Limited to 2-way angulation

Limited by inferior optics

Limited by poor illumination

Limited by inadequate biopsy samples

(As) Limited by small biopsy channel

Technical success TNE <5.9mm = cEGD

TNE high patient acceptability and

preference

Image quality

High definition

Image enhancement

Accuracy

TNE as good (?better) at diagnosing GORD related diseases

Recent data suggesting equivalent in diagnosing BO

Equivalent in diagnosing and grading varices

Possibly lower pick up small superficial gastric cancers in proximal stomach

Pick up may be improved with chromoendoscopy

Therapeutic ability

Bleeders – limited – channel for accessories/suction

Reduced cardiovascular stress

Therapeutic ability

Bleeders – limited

Narrower scope allows placement of wire

NJ tubes

Significantly quicker and easier

Is it better for patients?

Does improved patient tolerability

translate into a better quality endoscopy?

• Procedure time longer for TNE

• TNE 8.8 +/- 3.2 min vs 7.7 +/- 3.4 p = 0.021

• TNE 10 vs 7 min p=0.0042

1. Alexandris et al APT 20142. Despott et al Gut (Abstract) 2010

Is it better for the NHS?

Less staff allocation per room

No need for “head end” nurse

Shorter recovery time

Prep and procedure time longer

Mitigated if nurses do nasal prep

Lidocaine hydrochloride 5% + phenylephrine

hydrochloride 0.5%

Move out of the endoscopy

department?

Space in endoscopy at a premium

Outpatients

Community setting

Risk with upper GI endoscopy sedation related

Selected, low risk patients having diagnostic endoscopy

Barriers?

• Training

• Cost

Complications/considerations

Failure – rare

Epistaxis – self limiting 2%

Pressure and Naseptin for 1/52

Pack and ENT

Anticoagulants (no good data) – INR<2.5 (?)

Platelet count (no good data) >50 (?)

Slightly higher epistaxis rates (up to 14%)

Nasal fractures – usually not a problem

Frequent epistaxis, HHT contra-indication

Cost

No robust cost-benefit analysis

Cost savings with fewer nurses

Non sedated

Release space in endoscopy department

vs

Significant investment to provide dedicated TNE list

Switching from PO to TNE scope when opportunity arises

Summary

Is TNE technically as good as/better than traditional OGD?

Yes

Is it as good/better for patients?

Yes

Is it as good/better for the NHS?

Possibly ?
