Esophageal manometry

Esophageal manometry can be used to understand the movement of the esophagus. Esophagitis often presents with coordination of esophageal movements. Basic Information Specialist classification: Digestive examination classification: other examinations Applicable gender: whether men and women apply fasting: fasting Tips: Fasting foods that increase gastroesophageal reflux and acidity in the esophagus, such as: carbonated drinks, tea, coffee, alcohol, juice, tomatoes and sweets. Normal value 2.0-3.3 kPa (15-25 mmHg) with an average of 2.6 kPa (20 mmHg). Clinical significance LES (lower esophageal sphincter) base pressure ≤ 1.3 kPa (10 mmHg) suggesting gastroesophageal reflux. In order to understand the functional status of LES, the abdominal pressure can be increased during the examination to increase the intragastric pressure. Under normal circumstances, the LES pressure can be increased accordingly. The ratio of LES pressure to intragastric pressure should be >1, but the ratio of gastroesophageal reflux should be the above. ≤1 for diagnostic reference. Low results may be diseases: dysphagia, esophageal hiatal hernia, infantile gastroesophageal reflux, scleroderma esophagus, congenital esophageal stricture, congenital esophageal duplication, gastroesophageal reflux disease, high esophageal reflux malformation may be disease: Precautions for the middle esophagus 1. The antacid should be stopped 24 hours before surgery, and the proton pump blocker (such as omeprazole) should be stopped for more than 7 days. 2, can continue to take drugs that help determine the esophageal motility. 3, fasting for one night before surgery (at least 6 hours) to prevent aspiration. 4, sitting in the meal, meal time is controlled within 30min, two meals at least 4 hours apart, so as not to eat too much, leading to excessive swallowing exercise. 5. Fasting chewing gum. 6. Fasting foods that increase gastroesophageal reflux and acidity in the esophagus, such as: carbonated drinks, tea, coffee, alcohol, juice, tomatoes, and sweets. Inspection process 1. After inserting the pressure measuring catheter into the stomach, slowly pull the pressure measuring catheter. Observe the pressure pattern change on the computer screen. When the proximal channel enters the lower esophageal sphincter (LES) area, the pressure rises in this channel. Continue to pull the catheter out, and when the channel leaves the LES area, see the pressure drop below the baseline to calculate the length of the LES function zone (2-4 cm). 2. After the distal channel of the pressure measuring catheter leaves the LES area, the outer catheter is pulled 3 cm. At this time, the four channels are located at 3, 8, 13, and 18 cm on the LES. The patient was swallowed and recorded the amplitude, velocity and direction of the esophageal body. 3. The pressure measuring channel enters the upper esophageal sphincter (UES) to measure another general high pressure zone, which is the UES pressure. Not suitable for the crowd Inappropriate people: Generally there are no people who are not suitable. Adverse reactions and risks Generally no adverse reactions.
