Ways to “skin a cat”? • Text book definitions • Typical EGD diagnosis • Hill Grade • The “Simoni” method • Imaging
Text book • There are four types of hiatal hernia: • Type I hiatal hernia • Type II (paraesophageal) hiatal hernia • Type III hiatal hernia • Type IV hiatal hernia
Typical EGD reports • Incompetent GEJ • Small • Medium (moderate) • Large
Imaging • Upper GI: • Axial heightfromdiaphragm to • uppermostgastricfolds
The “Simoni” Method The best of all worlds?
Impelementing BRAVO pH System
Considered the best test for the diagnosis of gastroesophageal reflux disease (GERD) Greater sensitivity than endoscopy and greater specificity than an empiric trial of proton pump inhibitor (PPI) therapy.
Indications • GERD • Chronic Cough • Laryngitis • LPR • Chest pain (non-cardiac) • Regurgitation • Post-ARS evaluation • Failure to respond to PPIs
Current Technology and it’s Limitations Catheter Based Systems: • Patient Intolerance • Uncomfortable • Pharyngeal and Throat Discomfort • Runny Nose • Artifact Prone • Alters Regular Diet and Activity • Requires Manometry?
Bravo pH System™ • Catheter-Free pH Monitoring System • pH Capsule attached to the esophageal wall transmits data to pager-sized Receiver • Eliminates uncomfortable 24-hr trans-nasal catheter • Allows normal activities, showering and does not interfere with sleeping
Bravo pH System Components 1) Bravo Calibration Stand 2) Bravo pH Receiver 3) Bravo pH Capsule with Delivery System 4) Bravo pH Capsule 5) Bravo DataLink 6) Lithium AA Battery 7) Calibration Solutions (pH 7.01 & 1.07) 8) POLYGRAM NET pH Testing Application • Optional: Vacuum Pump
Bravo pH Capsule with Delivery System • For trans-nasal or trans-oral placement • Single-Use item • One-handed operation • 100 cm long with working length of 80 cm • Distance marks every 5 cm up to 60 cm Handle Catheter pH Capsule
Bravo pH Capsule with Delivery System • Bravo pH Capsule placed via nose or mouth • Trans-nasal placement relative to manometrically identified LES upper boarder • Trans-orally placement relative to endoscopically identified Scuama-Columnar Junction Flexible Tip pH Capsule
Bravo pH Capsule • pH Capsule measures esophageal pH with Antimony pH sensor • Uses Radio-Telemetry to send data to Receiver • Dimensions: 6 x 6.3 x 26 mm • Contains: suction chamber, locking pin, 2 batteries, PCB, transmitter and pH sensor+ref. pH Capsule
Capsule Attachment Step 1 Position Bravo Capsule Step 2 Apply Suction Step 3 Advance Pin Step 4 Release Capsule Step 5 Begin pH Recording
Bravo pH Receiver • pH Capsule transmits data to pager-sized Receiver • Eliminates uncomfortable 24-hr trans-nasal catheter • Allows showering and does not interfere with sleeping Receiver pH Capsule
Digital Radio-Telemetry • Use Digital Radio-Telemetry • Capsule measures pH every 6 sec and transmits data to receiver every 12 sec • Keep the receiver within 1m to prevent data loss (range up to 3m)
Bravo Performs Clinically - Summary • Bravo Market Studies Confirm/Validate Clinical Performance • Bravo’s Capsule is Comparable to the Conventional Catheter in Quantifying Esophageal pH* • The Bravo “Catheter-Free System” should Lead to Increased Patient Acceptance and Compliance of this Test for GERD*
RAPID pH Summary Simplified User Interface Intuitive software navigation Streamlined pH monitoring workflow Easy Study Management Reporting Options to Meet Your Needs Multiple options for graphically displaying study data Multiple templates enable customized reporting Flexible Integration Solutions Enables network printing and email options for reporting Enables study management and storage on network drives
