<prompt> In achalasia cardia, true is:Pressure at distal end increased with no peristalsisLow pressure at LES with no peristalsisPressure 50 mmHg with peristalsisPressure at the distal end increased with normal relaxation  <response>: Answer is A Pressure at distal end increased with no peristalsis: Achalasia is characterized by an increased pressure of LES and absence of esophageal peristalsis. Physiological Manometric features of Achalasia Elevated Resting pressure of LES 45 mmHgQ Incomplete LES relaxation in response to swallowingQ Absence of distal esophageal peristalsis
