    1. Optical coherence tomography of the pancreatic and bile ducts: are we ready for prime time?

      Optical coherence tomography of the pancreatic and bile ducts: are we ready for prime time?

      Background and study aims  First-generation optical coherence tomography (OCT) has been shown to increase diagnostic sensitivity for malignant biliary and pancreatic-duct strictures. A newer OCT imaging system, NVision Volumetric Laser Endomicroscopy (VLE), allows for in vivo cross-sectional imaging of the ductal wall at the microstructure level during endoscopic retrograde cholangiopancreatography (ERCP). The aim of this study was to identify and evaluate characteristics on OCT that are predictive of benign and malignant strictures. Patients and methods  Consecutive patients from six centers who underwent OCT between September 2016 and September 2017 were included in a dedicated registry. OCT images were analyzed, and ...

    2. Optical coherence tomography (OCT) prior to peroral endoscopic myotomy (POEM) reduces procedural time and bleeding: a multicenter international collaborative study

      Optical coherence tomography (OCT) prior to peroral endoscopic myotomy (POEM) reduces procedural time and bleeding: a multicenter international collaborative study

      Background Per-oral endoscopic myotomy (POEM) has emerged as an endoscopic treatment of achalasia. There are no pre-procedural imaging modalities to predict the safest and the most efficacious approach. Aim To evaluate the use of optimal coherence tomography (OCT) in providing a pre-procedural esophageal assessment. Methods Patients undergoing POEM from July 2013 to November 2015 were captured in a multicenter, international registry. Patients who underwent OCT pre-POEM (“OCT arm”) were compared to patients without pre-POEM OCT (“control arm”). OCT images were assessed for the degree of vascularity and the thickness of the circular muscular layer, and an approach was determined. Results ...

    3. Endoscopic optical coherence tomography as a tool to evaluate successful myotomy after a peroral endoscopic myotomy

      Endoscopic optical coherence tomography as a tool to evaluate successful myotomy after a peroral endoscopic myotomy

      Optical coherence tomography (OCT) provides imaging depth down to 3 mm and resolution of 7 μm over a 6-cm length over a 90 second scan. It is used to analyze tissue microstructure to scan for any potential abnormalities in the esophagus. As of now, the utility of OCT in assessing the esophageal muscular layers in achalasia patients after a peroral endoscopic myotomy (POEM) procedure has not been assessed. We present a case in which this device was used for this indication.
