Trans-nasal endoscopy – still sniffing
the NHS?
?
TNE

TNE
TNE – what it is…
Results in less gagging…
Can we advocate TNE?
Is TNE technically as good as traditional
OGD?
Is it as good for patients?
Is it as good for the NHS?
Is it…..?
Is TNE technically as good as/better than
traditional OGD? Diagnostic ability
Technical success

Light
Manoeuvrability
Accuracy
Therapeutic ability
Bleeders
Stents
PEG
NJ tube
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
“Scouting scope” in high risk individuals

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

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
www.freedomfromobesity.net
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 ?
