Safety and Efficacy of a Novel SpydrBlade Flexible Bipolar in POEM

Achalasia is an idiopathic motility disorder, primarily identified by the absence of esophageal peristalsis and the inability of the lower esophageal sphincter (LES) to relax properly. Although it is usually misdiagnosed and treated as gastroesophageal reflux disease (GERD), the main symptom is progressive dysphagia, accompanied by additional symptoms like nocturnal cough, heartburn, weight loss, regurgitation of undigested food and aspiration. The severity of achalasia and the effectiveness of treatments are commonly assessed using the Eckardt Symptom Score (ESS), which evaluates symptoms like weight loss, regurgitation, dysphagia, and retrosternal pain. Diagnosis of achalasia is often delayed, affecting up to 50% of patients. It typically involves a combination of diagnostic tools, such as time barium esophagram (TBE) study, which assesses the movement and clearance of barium in the esophagus; esophagogastroduodenoscopy (EGD), which allows visual examination of the esophagus, stomach, and duodenum; and high-resolution esophageal manometry (HREM), considered the gold standard for achalasia. HREM can also help stratify the condition into different types, influencing treatment choices. Furthermore, the endoluminal functional lumen imaging probe (Endoflip, Crospon Corp, Dangan Galaway, Ireland), which measures baseline parameters of LES, aiding in both diagnosis and treatment evolution. While there is no cure for achalasia, treatments aim to reduce LES pressure. The include …
