A commercial interest is any entity producing, marketing, re-selling, or distributing health care goods or services consumed by, or used on, patients.

� Instruments for Exposure of the Oral Cavity� Anesthesia – Nasal Intubation is preferred

� Epistaxis• Pre-op nasal endoscopy to document spurs,

deviated septum or other abnormality• Afrin and lubricated nasal trumpet while

patient is in preoperative holding area � Disposable Plastic cheek retractor� Dental splints � Jennings's mouth gag � Minnesota and Sweetheart

retractors

Basic Sialendoscopy Set

� Dilator System � Marchal Dilator System

� Probes No.0000 to No.8� Schaitkin’s Fluted Dilators \

� No.0 – 5� Conical Dilator � Helps to transition between dilators� Useful usually once papilla is dilated up to Marchal

No.1 or 2 dilator� Bougies (increasing diameter)

� Compatible with 0.4 mm guide wire� COOK Dilator System with Operating Sheath

� Guide Wire � Cook Dilators 1-8

� 100% Successful endoscopy

� Ductal or papillary stenosis in 7/15 (47%)

� Essentially normal endoscopy in 8/15 (53%)

� Symptoms improved in 13/15 (87%) cases

Diagnostic Sialendoscopy Data

Bowen M et al. Diagnostic and Interventional Sialendoscopy: A preliminary experience. 2010 Laryngoscope (accepted for publication)

� Progressive dilation� Marchal Dilator System

(No.0000 to No.6)

� Conical dilator

� Seldinger technique� Guide wire and bougies

� Papillotomy� 25% (7/28)

� Successful endoscopy� 96% (27/28)

Sialendoscope CannulationSERIAL DILATION USING THE DILATOR SYSTEM

SELDINGER TECHNIQUE USING GUIDE WIRE AND BOUGIES (adopted from Chossegros et al2)

Success of Diagnostic Endoscopy ~ 95-98%

Rate Limiting Step : Dilation of Papilla

� Approaches to the papilla

� Dilation technique

� Seldinger technique

� With bougies

� With sialendoscope

� Papillotomy

� Proximal papillotomy and sialodochoplasty

Papillotomy for diagnostic endoscopy…consequences..

Distal Papillotomy and Dilation Followed by Sialodochoplasty and Stent Placement

Avoid Complications

�Local Anesthesia:�-Lidocaine 4.5mg/kg (<300mg)�-Lidocaine/epineprine 7mg/kg (<500 mg)

�MAC (sedation):�-Over�-Under

�Local Anesthesia:�-Beware of ETT position�-NO atropine or like medication

Technical Problems

�Maceration of the papilla:�measured traction

�Avoid creating pseudo-orifices:�injection�forceps�dilators

Technical Problems

�Overinjection of NSS:�-60cc syringe with IV extender�-control your assistant enthusiasm�-maintain one port open�-in the submandibular area it can lead � to AIRWAY COMPROMISE

Technical Problems

�False Passage (papilla):�-do not force the dilator�-do not cut the papilla

�Ductal Perforation:�-do not advance blindly�-do not force the instrument in�-abort if identified

Equipment Failure

�Be cognizant of the turns:�-scope is semi-rigid (it is fragile) �-straighten the duct using manual traction

and pressure

�Be cognizant of the teeth

�Have back up gear
