UNASSIGNED: Background: The histopathology of the muscularis propria (MP) is unknown in @entity1 with @entity1318 . Endocytoscopy (EC) was developed as an ultra-high magnification endoscopy, and the submucosal tunnel created during peroral endoscopic myotomy (POEM) not only provides access to the MP but also enables subsequent endoscopic assessment of the MP. @entity1 and methods: In seven @entity1 with @entity1318 (mean  SD; 35  18.1 years; @entity1 : @entity1 , 4:3) who underwent POEM (myotomy length: 12  2.2cm), subsequent EC examination was performed from the mid-esophagus to the gastric side. EC images were compared to the results of histopathologic examination (two biopsies from the mid-esophagus and lower esophageal sphincter), which was the standard. Results: In all @entity1 , favorable EC images were obtained, and spindle-shaped smooth muscle cells were detected. In our series, we observed no notable features such as @entity194 or @entity1184 of smooth muscle cells. In addition, the EC assessment was consistent with the results of biopsy. No complications were encountered during any of the procedures. Conclusion: In a clinical setting, real-time assessment of the MP using EC is feasible. This technique may play an important role in determining the pathology of @entity1318 and other diseases that affect gastrointestinal function.
