'''Achalasia''' is a benign pathology of the [[esophagus]].


==General==
*Uncommon.
*Risk factor for [[squamous cell carcinoma]] (in men and women) and [[esophageal adenocarcinoma|adenocarcinoma]] (in men).<ref>{{Cite journal  | last1 = Zendehdel | first1 = K. | last2 = Nyrén | first2 = O. | last3 = Edberg | first3 = A. | last4 = Ye | first4 = W. | title = Risk of esophageal adenocarcinoma in achalasia patients, a retrospective cohort study in Sweden. | journal = Am J Gastroenterol | volume = 106 | issue = 1 | pages = 57-61 | month = Jan | year = 2011 | doi = 10.1038/ajg.2010.449 | PMID = 21212754 }}</ref>

Clinical:
*Dysphagia (difficulty swallowing) liquids ''and'' solids.<ref name=pmid24395614/>

*Endoscopic dilation.
*[[Peroral endoscopic myotomy]] (POEM).
*Laparoscopic myotomy.
==Microscopic==
Features:<ref name=pmid16128783>{{Cite journal  | last1 = Kjellin | first1 = AP. | last2 = Ost | first2 = AE. | last3 = Pope | first3 = CE. | title = Histology of esophageal mucosa from patients with achalasia. | journal = Dis Esophagus | volume = 18 | issue = 4 | pages = 257-61 | month =  | year = 2005 | doi = 10.1111/j.1442-2050.2005.00478.x | PMID = 16128783 }}</ref>
*Mucosa typically normal - even in long-standing achalasia.
Note:<ref name=pmid16128783/>
*Achalasia seen in the context of a resection usually has inflammation.
*Post-Heller myotomy often has inflammation.
