Given Imaging Announces New Studies Highlighting Diverse Applications of ManoScan™ High Resolution Manometry

LAS VEGAS, NV--(Marketwire - Oct 22, 2012) - Given Imaging Ltd (NASDAQ: GIVN), a world leader in GI medical devices and pioneer of capsule endoscopy, today announced data from numerous studies highlighting the value of ManoScan™ high resolution manometry in assessing esophageal and anorectal muscle function. The studies are being presented at the American College of Gastroenterology 2012 annual meeting taking place in Las Vegas from October 19-24, 2012. Given Imaging is exhibiting at booth #1325 throughout the conference.

Poster presentations about high resolution esophageal manometry include:

  • "Esophageal Dysmotility Increases with the Severity of Gastroesophageal Reflux Disease: A Study Using High Resolution Manometry and the Revised Chicago Classification Criteria," (P9) by Stephen Ou, MD, University of California-Irvine Medical Center, Orange, CA and colleagues, retrospectively reviewed 150 cases in which high resolution manometry was performed on patients presenting with GERD symptoms. Researchers from the University of California-Irvine Medical Center applied the revised Chicago Classification criteria to each previously performed case to determine the prevalence of dysmotility among the patients. The researchers concluded that esophageal dysmotility, characterized by the new Chicago Classification criteria, increases with the severity of esophageal acid exposure. 

  • "High Resolution Manometry Metrics in the Upright Position: A Validation Study," (P579) by Andrew Read, MD, Northwestern University Feinberg School of Medicine, Chicago, IL and colleagues, found that normative ranges for high resolution manometry metrics decreased significantly when the test was performed in the upright position compared with the supine position. Researchers from the Department of Medicine, Northwestern University Feinberg School of Medicine, compared high resolution manometry metrics including integrated relaxation pressure, distal contractile integral, contractile front velocity and distal latency in tests conducted in the upright or supine position. Due to the significant decreased normative range of the metrics in the upright position, researchers suggested that the cut-off values for abnormal function should be adjusted if high resolution manometry is performed in the upright position. 

  • "A Study of Interobserver Agreement with High Resolution Esophageal Pressure Topography and Impedance Manometry," (P582) by Erick R. Singh, MD, Georgia Health Sciences University, Augusta, GA and colleagues, used high resolution impedance and high resolution manometry testing to assess bolus transit and identify esophageal contraction patterns to give a more complete study of esophageal function. Researchers from the Division of Gastroenterology, Georgia Health Sciences University, found an incremental benefit in diagnosing esophageal dysfunction with the addition of high resolution impedance to high resolution manometry.

Poster presentations about high resolution anorectal manometry include:

  • "High Resolution Anal Pressure Topography in Chronic Constipation and Healthy Asymptomatic Volunteers," (P1565) by Vanessa Costilla, MD, Mayo Clinic Arizona, Scottsdale, AZ, and colleagues, presented data from one of the first studies to use high resolution anorectal manometry to compare the anorectal pressure measures of chronic constipation patients with healthy, asymptomatic patients. Researchers from Mayo Clinic Arizona and Dartmouth-Hitchcock Medical Center completed 2-D HRM using ManoScan to find that patients with chronic constipation had significantly lower anorectal resting pressure, initial squeeze pressure, terminal squeeze pressure, squeeze fatigue rate and anal canal length compared with the healthy patient group. Chronic constipation patients also demonstrated a significantly higher urge to defecate and increased balloon expulsion time compared with the healthy patient group. The researchers concluded that anorectal high resolution manometry facilitates the evaluation of anorectal dynamics.

"As we continue to learn about the clinical value of ManoScan high resolution manometry through studies such as those presented at this conference, it is clear that it provides us with important new information about esophageal pressure and motor function as well as anorectal function that can help us more effectively treat GI diseases," said John Pandolfino, MD, Northwestern Memorial Hospital, Chicago, IL. "This technology provides physicians with valuable information that could potentially help correlate patient symptoms with measurements of esophageal and anorectal function."
