Eligibility Criteria:
Inclusion Criteria:~* \> or = to 18 years of age~* Referred for evaluation and treatment of benign esophageal luminal narrowing~* Clinical diagnosis of benign esophageal luminal narrowing with documentation and imaging~* Adult patients with benign refractory esophageal strictures referred for placement of an esophageal stent are eligible for this study~* Willing and able to give informed consent~* No condition or comorbidity which would prevent the patient from undergoing a successful upper endoscopy~Exclusion Criteria:~* \< 18 years of age~* Pregnancy~* History of prior endoscopic dilation\* (\*unless referred for placement of stent)~* Coagulopathy~* Inability to traverse the stricture using standard techniques~* Patients unable to provide consent

Study Arms:
- EndoFLIP Measurements (Type: None): 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.

Based on this trial design, predict the completion outcome and termination type (if applicable).
