No obvious abnormalities were found in his initial examinations including upper digestive endoscopy, upper gastrointestinal imaging and chest computed tomography (CT). During the subsequent introduced-peroral endoscopic myotomy (POEM), it was found that the mucosal layer and the muscular layer had severe adhesion, which did not receive much attention, delayed the clear diagnosis and effect treatment, and ultimately led to a poor prognosis for the patient.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>This case suggests that when patients with AC found mucosal and muscular adhesions during POEM surgery, the possibility should be considered that the lesion may be caused by a malignant lesion.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13019-024-02688-w","type":"journal-article","created":{"date-parts":[[2024,4,15]],"date-time":"2024-04-15T03:26:48Z","timestamp":1713151608000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Abnormal performance of peroral endoscopic myotomy (POEM): a case misdiagnosed as achalasia of cardia"],"prefix":"10.1186","volume":"19","author":[{"given":"Wen-Quan","family":"Yu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui-Jiang","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li-Xue","family":"Zhai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Cheng","family":"Wei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,4,15]]},"reference":[{"key":"2688_CR1","doi-asserted-by":"publisher","first-page":"1841","DOI":"10.1001\/jama.2015.2996","volume":"313","author":"JE Pandolfino","year":"2015","unstructured":"Pandolfino JE, Gawron AJ.
