A multicenter study published in the December 2013 issue of Clinical Gastroenterology and Hepatology reports that fewer than one-third of GI endoscopy centers are equipped to provide the necessary high-level imaging needed to reliably identify pre-cancerous lesions in patients with Barrett's Esophagus, according to William Hale, chief of gastroenterology at Norwalk Hospital.

The Endoscopy Unit at Norwalk Hospital has been using high-resolution imaging equipment for several years, Hale said. The physicians who perform procedures in the GI Unit are experienced in the use of high-definition endoscopes and narrow-band imaging, the specific techniques recommended by the American College of Gastroenterology, he added.

Barrett's Esophagus is a pre-cancerous condition that may occur in the setting of chronic acid reflux, he said. Patients with Barrett's Esophagus have regular endoscopy surveillance to detect pre-cancerous changes and then those patients are treated with specialized endoscopic ablation techniques.

In addition to its state-of-the-art imaging capabilities, Norwalk Hospital's Endoscopy Unit offers both radio-frequency ablation and liquid nitrogen cryotherapy for the treatment of pre-cancerous Barrett's Esophagus.
