Background and Aims
Schatzki rings are found in the distal esophagus, are associated with hiatal hernias,
and present with intermittent dysphagia to solid foods. They can be identified by
radiology (GI series or barium swallow studies) or endoscopy. Rings are not always
visualized during endoscopy in patients in whom they are suspected clinically. The
Bolster technique involves application of epigastric abdominal pressure, which offers
the potential to reveal a Schatzki ring that is otherwise obscured within a reduced
hiatal hernia. The aim of this study was to determine whether the Bolster technique
improves endoscopic detection of Schatzki rings.
Methods
We reviewed 30 symptomatic patients with a history of a Schatzki ring in a tertiary
care center. The Bolster technique was applied to patients in whom the ring was not
visible during standard endoscopy. The main outcome measurement was identification
of the Schatzki ring after the Bolster technique.
Results
A Schatzki ring was visible during standard endoscopy in 26 of the 30 patients. In
the remaining 4, the ring was visible only after the application of the Bolster technique.
Conclusion
The Bolster technique is a simple maneuver that can increase detection rates of Schatzki
rings during endoscopy.

- Yet another provocative maneuver to accentuate Schatzki ringsGastrointestinal EndoscopyVol. 84Issue 4
- PreviewI read the New Methods article by Dr Jouhourian and colleagues1 with great interest.1 In brief, the authors describe a novel maneuver (Bolster technique) that may be used to accentuate and diagnose what may be a suspected but “hidden” Schatzki ring. The authors’ report also reviewed other techniques that have been used by radiologists. I have yet another option. Over 25 years ago, I had the privilege of training under Dr Donald O. Castell. When a suspected Schatzki ring was not visualized during upper GI endoscopy, Dr Castell suggested that we simply have the patient deeply inspire while the endoscope was positioned in the distal esophagus.
