Study type | Observational |
The purpose of this study is to investigate the use of a functional luminal imaging probe to characterize benign esophageal luminal strictures before and after dilation and identify predictors of response to therapy. Patients will be evaluated during endoscopy using functional luminal imaging (EndoFLIP; Crospon Medical Devices, Galway, Ireland) to characterize the geometry of benign luminal esophageal narrowing before and after dilation.

Eligibility |
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 |

Primary | Collection of Measurements of the Luminal Narrowing Using EndoFlip | The study is observational and a proof of concept study. Measurements of the luminal narrowing using EndoFLIP will be obtained. | 12 Months | |
Secondary | Observation of Pre-Endoscopic Therapy EndoFLIP Measurements | 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. | 12 Months | |
Secondary | Observation of Post-Endoscopic Therapy EndoFLIP Measurements | 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. | 12 Months |
