We are pleased to announce that a paper by Dr. Kei Ushikubo,

“Endoscopic Pseudo-dilation of Esophagogastric Junction During Peroral Endoscopic Myotomy”

has been published in DEN Open.　https://doi.org/10.1002/deo2.70360

This study defined “pseudo-dilation” as a phenomenon in which the esophagogastric junction (EGJ) appears dilated immediately after submucosal tunneling, even before myotomy is performed during POEM, and investigated its clinical significance.

Pseudo-dilation was observed in 95.4% of patients, highlighting the need for careful interpretation of endoscopic EGJ opening during POEM.

This study provides important insights into the intraoperative assessment of POEM.

Congratulations, Dr. Ushikubo!
