Safety and Efficacy of Gastric Per Oral Endoscopic Myotomy (G-POEM) in Patients With Refractory Gastroparesis
Safety and Efficacy of Gastric Per Oral Endoscopic Myotomy (G-POEM) in Patients With Refractory Gastroparesis
Refractory gastroparesis is a disease characterized by a delayed gastric emptying without a mechanical obstruction. Actual treatments have a limited efficacy and gastric per-oral endoscopic myotomy (G-POEM) is a new treatment that has demonstrated initial promising results in these patients. The investigators aims are to evaluate security and efficacy of this endoscopic treatment in participants with refractory gastroparesis.
Gastroparesis is a chronic, condition characterized by a delayed gastric emptying without a mechanical obstruction. This disease is associated with high morbidity and mortality with a prevalence up to 4% of population. Patients with this disease have a reduced quality of life. The principal etiologies include: post-surgical, diabetes, medications and idiopathic. Symptoms include nausea, vomiting, early satiety, bloating and abdominal pain. Diagnosis is based on the combination of symptoms and studies as gastroscopy that shows retained food in the stomach without a gastric outlet obstruction and confirmed with a gastric emptying scintigraphy. Treatments have limited effect in these patients, including medications, botulinum toxin injection, surgical gastric electrical stimulation, laparoscopic pyloroplasty and stent placement. G-POEM is a new technique based on per-oral endoscopic myotomy treatment in achalasia patients, which has been recently proposed for treatment of patients with refractory gastroparesis with good initial results. The investigators aim is to evaluate the safety and efficacy of this new technique in a group of mexican participants with this disease.
