ORANGEBURG, N.Y., May 17, 2012 (GLOBE NEWSWIRE) -- Vision-Sciences, Inc. (Nasdaq:VSCI), a leading provider of unique flexible endoscopic products utilizing its proprietary sterile disposable EndoSheath® technology, today announced positive findings from a 426-patient multi-center research study evaluating the feasibility, safety, acceptability, and yield of unsedated transnasal esophagoscopy (TNE) using Vision-Sciences' EndoSheath technology to diagnose esophageal neoplasia. The study, entitled "Feasibility, safety, acceptability, and yield of office-based, screening transnasal esophagoscopy," was published in the May 2012 issue of the peer-reviewed journal Gastrointestinal Endoscopy.

The study authors concluded that unsedated TNE is a feasible, safe and well-tolerated method to screen for esophageal disease in a primary care population.

"The results of this significant research demonstrate the simplicity and efficacy of the TNE procedure and our EndoSheath technology," stated Cynthia Ansari, CEO of Vision-Sciences. "A key component to managing growing esophageal cancer rates is early detection, and our TNE system represents the best solution for patient management and cost effective diagnostic examinations."

Esophageal adenocarcinoma is one of the fastest growing cancers in the United States and most people who develop the disease have not previously been screened nor had a precancerous lesion identified. An emerging procedure, TNE allows for immediate visual diagnosis and treatment of the esophageal anatomy. The procedure involves inserting a small, thin endoscope through the nose of a patient to view the larynx, esophagus, and stomach without requiring sedation, as is common with larger endoscopes. Vision-Sciences' TNE system uses EndoSheath technology, which ensures sterility and provides the physician with greater practice efficiency.

Of the 426 patients enrolled in this study, 38% of participants had an esophageal diagnosis which changed treatment management, including the detection of Barrett's Esophagus, a potential precursor to cancer. Importantly, patients generally reported that the procedure was well-tolerated, with 99% of those enrolled completing the examination (n=422).  The mean examination time was 3.7 minutes.  No serious adverse events were reported, and 2.8% of participants reported minor complications (n=12). Researchers determined that a screening program using EndoSheath technology could be much more cost-efficient than the current models. The study was conducted at two outpatient tertiary-care centers.

Vision-Sciences will exhibit its TNE system and EndoSheath technology at two upcoming medical conferences: Digestive Disease Week (DDW) 2012 (May 20-22; booth #2219) and the American Society for Metabolic and Bariatric Surgery (ASMBS) 29th Annual Meeting (June 19-21; booth #210).  Both conferences will be held in San Diego, California.  DDW, one of the largest medical conferences in the world, attracts approximately 15,000 digestive disorder physicians, surgeons, researchers and academics from around the world who take part in scientific courses, and research presentations, as well as hands-on instructional courses. The ASMBS conference attracts over 2,000 surgeons, physicians, and integrated health professionals specializing in the area of weight loss treatment and surgery.
