The per-oral endoscopic myotomy, or POEM, is a minimally invasive surgical procedure for the treatment of achalasia wherein the inner circular muscle layer of the lower esophageal sphincter is divided through a submucosal tunnel. [1] This enables food and liquids to pass into the stomach, a process that is impaired in achalasia.

Esophageal rings or strictures may be treated with esophageal dilation. Simple observation may be considered, [5] especially if symptoms are minimal or absent. If symptoms are severe or persistent, peroral endoscopic myotomy (POEM) may be offered. [2]
Myotomy is a surgical procedure that involves cutting a muscle to relieve constriction, often performed in the gastrointestinal or urological systems. The procedure can alleviate symptoms caused by muscle-related functional obstructions, particularly in cases of achalasia, a disorder that affects the esophagus.
In 2003, he reported the world's first "circumferential" EMR for Barrett's esophagus with high-grade dysplasia, where the esophagus was stripped of its pre-cancerous mucosa around a 360 degrees. In 2008, he performed the world's first clinical case of per-oral endoscopic myotomy (POEM), a treatment for achalasia , building upon the pig model ...
Both of these features impair the ability of the esophagus to empty contents into the stomach. Patients usually complain of dysphagia to both solids and liquids. Dysphagia to liquids, in particular, is a characteristic of achalasia. Other symptoms of achalasia include regurgitation, night coughing, chest pain, weight loss, and heartburn.
Individuals with diffuse esophageal spasm or nutcracker esophagus, due to disordered peristalsis propagation, may experience severe chest pain and dysphagia, mimicking cardiac ischemia. [3] Achalasia's most common symptoms include dysphagia (difficulty swallowing solids and liquids), regurgitation of undigested food, respiratory issues ...
Nutcracker esophagus is one of several motility disorders of the esophagus, including achalasia and diffuse esophageal spasm. It causes difficulty swallowing with both solid and liquid foods, and can cause significant chest pain; it may also be asymptomatic. Nutcracker esophagus can affect people of any age but is more common in the sixth and ...
