G-POEM in patients with gastroparesis - gambling for healing or bigger armamentarium ? A case series and review of the literature.

Approximately 30% of all affected patients suffering from gastroparesis do not respond to any available treatment modality. Gastric peroral endoscopic myotomiy (G-POEM, antropyloromyotomy) represents a new principle of therapy. In this single center study, G-POEM showed a high technical success rate with a very low procedural complication rate. However, the clinical response beyond a short-term post-interventional improvement did not succeed in a single patient. The heterogeneity of the clinical picture, which represents a spectrum of different pathophysiological, etiological and clinical characteristics, still requires a therapy tailored to the individual patient. G-POEM should be considered especially in patients with pylorus-dominant gastroparesis.
