In achalasia cardia, true is:: (A) Pressure at distal end increased with no peristalsis, (B) Low pressure at LES with no peristalsis, (C) Pressure > 50 mmHg with peristalsis, (D) Pressure at the distal end increased with normal relaxation
Answer is A. 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 mmHg)Q Incomplete LES relaxation (in response to swallowing)Q Absence of distal esophageal peristalsis
