Write answer in between .Q:A previously healthy 49-year-old woman comes to the emergency department because of chest pain that radiates to her back. The pain started 45 minutes ago while she was having lunch. Over the past 3 months, she has frequently had the feeling of food, both liquid and solid, getting stuck in her chest while she is eating. The patients vital signs are within normal limits. An ECG shows a normal sinus rhythm with no ST-segment abnormalities. An esophagogram is shown. Further evaluation is most likely to show which of the following?? A: Simultaneous multi-peak contractions on manometry, B: Multiple mucosal erosions on endoscopy, C: Elevated lower esophageal sphincter pressure on manometry, D: Gastroesophageal junction mass on endoscopy, E: Hypertensive contractions on manometry,  <response>: This is a clinical vignette describing a 49-year-old woman with chest pain radiating to her back that started while she was eating lunch. She also has a 3-month history of dysphagia food getting stuck in her chest. Her vital signs and ECG are normal. The esophagogram shows a dilated esophagus. Based on the acute onset of chest pain while eating and chronic dysphagia, this suggests an esophageal motility disorder as the cause. The normal ECG rules out cardiac causes. The choices describe findings that may be seen on manometry or endoscopy in esophageal motility disorders.Simultaneous multi-peak contractions on manometry would indicate diffuse esophageal spasm. Multiple mucosal erosions on endoscopy would suggest reflux esophagitis. Elevated LES pressure on manometry would indicate achalasia. A GE junction mass on endoscopy would be concerning for malignancy. Hypertensive contractions on manometry would indicate nutcracker esophagus. Of these choices, diffuse esophageal spasm best fits the clinical presentation.A: Simultaneous multi-peak contractions on manometry
