Summary
The InScope Optical Dilator offers safe and effective esophageal dilation for strictures by combining direct visualization with tactile feedback. This method provided substantial relief for patients with dysphagia, with no reported complications.
Area of Science:
- Gastroenterology
- Endoscopic procedures
- Esophageal diseases
Background:
- Esophageal dilation is crucial for managing benign strictures.
- Direct visualization and tactile feedback enhance dilation safety and efficacy.
- The InScope Optical Dilator integrates these features for improved outcomes.
Purpose of the Study:
- To evaluate the safety and efficacy of the InScope Optical Dilator for benign esophageal strictures.
- To assess patient outcomes and endoscopist experience with the device.
Main Methods:
- A prospective study involving 26 patients with peptic strictures or Schatzki's rings.
- Utilized a 27F or 29F endoscope with the InScope Optical Dilator.
- Employed three dilator sizes (14-20 mm) based on stricture assessment.
Main Results:
- Twenty-six patients (17 peptic strictures, 9 Schatzki's rings) underwent dilation.
- Patients reported substantial relief from dysphagia post-dilation.
- No complications occurred; endoscopists reported high visualization and typical bougie experience.
Conclusions:
- The InScope Optical Dilator provides direct visualization during esophageal dilation.
- It maintains tactile sensation and offers sequential dilation with a single passage.
- The device is safe and effective for treating benign esophageal strictures.
