[Novelties in digestive endoscopy: three promising endoscopic procedures].

Several new techniques have recently been introduced in digestive endoscopy. Among these are anti-reflux mucosectomy (ARMS) or mucosal ablation (ARMA) which have demonstrated efficacy in the treatment of patients with refractory gastro-esophageal reflux disease. Both can be considered in the absence of a large hiatal hernia. Comparable to the well-established peroral endoscopic myotomy (POEM) for the treatment of achalasia, gastric POEM (G-POEM), an endoscopic antro-pyloromyotomy, represents an endoscopic technique for the treatment of gastroparesis, including diabetic, post-surgical and idiopathic subtypes. Finally, endoscopic ultrasound-guided radiofrequency ablation (EUSRA) can be considered as alternative to surgery in selected patients with small tumoral lesions of the pancreas.
