To define the role of a functional luminal imaging probe (EndoFLIP) in benign upper GI luminal narrowing. EndoFlip measurement of the cross sectional area of the narrowing will be obtained prior to and after endoscopic dilation. Patients will follow up for repeat endoscopy and dilation if indicated. EndoFLIP measurements will be made again before and after dilation. The use of EndoFlip may offer insight in to the clinical and endoscopic predictors of successful stricture dilation.
The Endolumenal Functional Lumenal Imaging Probe Imaging System is a technology developed to measure the dimensions & function of a variety of hollow organs throughout the body. Since receiving FDA clearance for sale in the United States EndoFLIP has been used in a variety of clinical applications. We intend to investigate the potential clinical applications of EndoFLIP in the upper GI tract in patients with esophageal stenoses who require endoscopic therapy for benign esophageal strictures. The use of EndoFLIP to characterize a stricture pre- & post- dilation may offer insight in to the clinical and endoscopic predictors of successful stricture dilation, & what characteristics determine & predict refractory & recurrent strictures.

- Collection of Measurements of the Luminal Narrowing Using EndoFlip [ Time Frame: 12 Months ]The study is observational and a proof of concept study. Measurements of the luminal narrowing using EndoFLIP will be obtained.
- Observation of Pre-Endoscopic Therapy EndoFLIP Measurements [ Time Frame: 12 Months ]Patients will undergo the clinically indicated procedure for benign esophageal luminal narrowing remediation. Before undergoing clinically indicated esophageal therapy, measurements of the luminal narrowing using EndoFLIP will be obtained to identify potential predictors of response to endoscopic therapy. These measurements will included luminal diameter, length of narrowing and narrowing distensibility and will be obtained before and after delivery of the clinically indicated endoscopic therapy.
- Observation of Post-Endoscopic Therapy EndoFLIP Measurements [ Time Frame: 12 Months ]After undergoing clinically indicated esophageal therapy at clinically-indicated follow-up endoscopies, measurements of the luminal narrowing using EndoFLIP will again be obtained to identify responses to endoscopic therapy.
