Achalasia in a Patient with Myotonic Dystrophy.

Achalasia in a Patient with Myotonic Dystrophy. Intern Med. 2019 Sep 11;: Authors: Sato H, Mizuno KI, Hashimoto S, Takatsuna M, Terai S Abstract Myotonic dystrophy is a progressive disorder mainly affecting the voluntary muscles. We herein report a rare case of myotonic dystrophy complicated with high-resolution manometry-defined achalasia, the pathology of which is absent relaxation of the smooth muscles of lower esophageal sphincter (LES). In the present case, achalasia was considered a complication of myotonic dystrophy instead of sporadic achalasia, as on performing high-resolution manometry, the finding of an impaired LES relaxation (myotonic phase) changed to a totally emaciated LES function (muscle weakness phase) as myotonic dystrophy progressed.
