These procedures induce scarring of the artificial ulcer at the gastric cardia, which tightens the enlarged cardiac opening. However, we encountered patients with unresolved symptoms due to insufficient cardiac shrinkage despite multiple ARMS\/ARMA treatments. This study analyzed the frequency and characteristics of the refractory cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively reviewed patients who underwent ARMS\/ARMA treatments at our institution from January 2014 to October 2022.

The male\u2010to\u2010female ratio was 5:2, with a mean age of 70 (58\u201373) years, and a mean BMI of 20.4 (20.0\u201324.0).

Finally, three cases were managed with medication, while four required surgical fundoplication, which improved their symptoms.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Approximately 5% of ARMS\/ARMA cases could not achieve sufficient cardiac shrinkage.
