To Investigate the Incidence of Reflux in Patients After Per-oral Endoscopic Myotomy in Achalasia Cardia Patients

Peroral endoscopic myotomy involves an initial incision on the internal lining of the oesophagus. This permits entry of the endoscope to within the wall of the oesophagus, where the muscle will be exposed. The inner layer of the muscle near the lower oesophagal sphincter will be cut (this is termed myotomy). At the conclusion of the procedure, the oesophagal incision will be closed with standard endoscopic clips.
