ORLANDO, Fla., May 20, 2013 (GLOBE NEWSWIRE) -- Given Imaging Ltd, (Nasdaq:GIVN), a world leader in GI medical devices and pioneer of capsule endoscopy, today announced several studies confirming an expanded role for SmartPill in diagnosing gastrointestinal motility disorders. All data were presented at Digestive Disease Week ® (DDW) taking place May 18 - 21, 2013 at the Orange County Convention Center, Orlando, FL where Given Imaging is exhibiting at booth #1059 throughout the conference. "The SmartPill motility monitoring system gives us a complete GI profile that allows us to recognize multiregional transit irregularities in patients with possible upper or lower GI dysmotility," said Braden Kuo, M.D., Director, Gastrointestinal Motility Laboratory, Massachusetts General Hospital. "These new studies add to the growing body of data showing that SmartPill is an extremely valuable tool enabling us to diagnose and treat motility disorders for better patient care." A key poster presentation, Wireless Motility Capsule Alters Diagnosis and Affects Clinical Management in Patients with Suspected Gastrointestinal Dysmotility, poster Mo2092, presented by Shreya Raja, M.D., Division of Gastroenterology and Hepatology, Johns Hopkins School of Medicine, and colleagues, retrospectively examined how SmartPill findings affect clinical care. The study reviewed numerous data points including pressure, pH and temperature data collected by SmartPill to determine the diagnostic yield of wireless motility capsule and assess changes in 51 consecutive patients with suspected dysmotility. Clinical management decisions after the SmartPill procedure, including medication changes, referrals for additional diagnostic tests, and outside referrals, were also analyzed. Results show that data collected by SmartPill impacts patient care by altering diagnosis and clinical management. Alteration in diagnosis was frequent and change in medication was made for the majority of patients with abnormal testing results. Furthermore, normal SmartPill testing changed clinical management in over 50% of cases. Several additional studies presented during DDW highlight the value of SmartPill for the evaluation and diagnosis of different motility conditions. Studies include:
- Potential Role for Ileocecal Valve Dysfunction and Small Intestinal Dysmotility in Bacterial Overgrowth As Assessed by Wireless Motility Capsule, poster Mo2059, presented by Bani Chander Roland, M.D., Department of Internal Medicine, Johns Hopkins School of Medicine, and colleagues, assessed the relationship of ileocecal valve (ICV) pressures with lactulose breath test (LBT) results, characterized the relationship of prolonged small bowel transit time (SMTT) with LBT, and assessed the relationship of gastric/small bowel pH and pressures with LBT using SmartPill testing. Results show that low ICV pressures are significantly associated with small intestinal bacterial overgrowth (SIBO). Furthermore, prolonged SBTT is also highly associated with SIBO. There is no association between delayed SBTT and low ICV pressure, suggesting that these mechanisms independently contribute to SIBO. These findings may help clarify SIBO pathogenesis and lead to more patient-specific treatment strategies.
- Use of Additional Wireless Motility Capsule (WMC) Parameters Improves Gastrointestinal Landmark Identification, poster Mo2104, presented by Sonia Yoon, M.D., GI Medicine, Massachusetts General Hospital, and colleagues, sought to identify gastric emptying (GET), and small bowel (ICJ) and colonic transit times by pH alone and to determine if utilization of SmartPill motility monitoring which include other parameters could increase the yield and precision in determining GI transit landmarks. The results of 168 patients showed that SmartPill analysis using the additional parameters such as frequency and amplitude, FFT analysis and temperature increases the yield for landmark identification compared to pH alone.
- Small Intestinal Transit Time Is Prolonged in Patients with Small Intestinal Bacterial Overgrowth, poster Mo2068, presented by Bani Chander Roland, M.D., Department of Internal Medicine, Johns Hopkins School of Medicine, and colleagues, analyzed the relationship of prolonged small bowel transit time (SBTT) in patients undergoing SmartPill motility monitoring with positive lactulose breath test (LBT) and to assess the relationship of prolonged gastric, colonic and whole gut transit times with positive LBT. The retrospective study looked at 72 consecutive patients who were referred for motility testing with 37 patients who underwent both SmartPill and LBT. Results showed that patients with underlying small intestinal bacterial overgrowth have significant delays in SBTT as compared to those without. The correlation between prolonged SBTT and positive LBT may be useful in identifying those patients with underlying SIBO and could suggest therapeutic options for those refractory to standard therapy.
