Long Vs Short Poem for the Treatment of Achalasia. Interim Analysis of A Randomized Controlled Trial

The use of Per-Oral Endoscopic Myotomy (POEM) for the treatment of achalasia has been increasing in the last years. However, some technical issues remain to be defined. In the published series a long myotomy (12cm) was usually performed. Surgical myotomy is typically shorter, being protracted for about 8cm. We report on the interim analysis of a randomized controlled trial that evaluates the outcomes of POEM according to the length of the myotomy.
