Gastroenterologists commonly dilate non-obstructive dysphagia using different techniques and patient profiles than peptic strictures. Empiric dilation for dysphagia is more frequent and requires fewer repeat procedures.

Area of Science:

  • Gastroenterology
  • Endoscopy

Background:

  • Non-obstructive dysphagia management practices among U.S. gastroenterologists are not well-defined.
  • Understanding these patterns is crucial for optimizing patient care and resource allocation.

Purpose of the Study:

  • To investigate and characterize the practice patterns in the management of non-obstructive dysphagia.
  • To compare empiric dilation for non-obstructive dysphagia with dilation for peptic strictures.

Main Methods:

  • Analysis of a large endoscopic data repository (Clinical Outcomes Research Initiative, CORI) from 100 U.S. gastroenterology practices (1998-2003).
  • Evaluation of 181,261 initial esophago-gastro-duodenoscopies (EGDs) in adult patients.
  • Comparison of 7,256 patients receiving empiric dilation for non-obstructive dysphagia versus 5,764 patients undergoing dilation for peptic strictures.

Main Results:

  • Patients undergoing empiric dilation were younger, had a higher proportion of women, and less frequent reflux symptoms or erosive esophagitis compared to the peptic stricture group.
  • Empiric dilations predominantly used rubber bougies, while stricture dilations often employed guidewires.
  • Larger dilator diameters were used for empiric dilations, and repeat dilations within one year were less common (4%) compared to stricture dilations (13%).

Conclusions:

  • Empiric dilation for non-obstructive dysphagia is a prevalent clinical practice among U.S. gastroenterologists.
  • This practice involves a distinct patient population and employs different dilation techniques compared to the management of peptic strictures.
  • The findings suggest variations in diagnostic and therapeutic approaches based on dysphagia etiology.
