Initial experience with peroral endoscopic myotomy in Bulgaria: case series

Achalasia is a rare motility disorder with unknown etiology that results in failure of relaxation of the lower esophageal sphincter (LES). As there is no etiological treatment, different pharmacological agents and invasive techniques have been used for relieving the symptoms. For the past decade, peroral endoscopic myotomy (POEM) has proven to have excellent results. We present a retrospective study of five patients that underwent POEM for primary achalasia. We used anterior approach for the submucosal tunneling. The procedure showed immediate results and no severe short- or long-term adverse events. We have been following the patients up for more than 3 years now. Since its invention more than ten years ago, the POEM procedure and its advantages and disadvantages compared to the pneumatic dilatation and the Heller myotomy have been extensively studied. There is still no universal opinion on which procedure should be the first line treatment.
