Upper Gastrointestinal Function Determination and Imaging

Upper gastrointestinal function measurement and imaging include the determination of the esophagus, gastroesophage, gastric emptying, and gastrointestinal tract, and better diagnosis of abnormal conditions. The subject was fasted for more than 4 hours, and the examination method was the same as that of hepatobiliary. When the common bile duct and duodenum were developed, 300 ml of milk was used to promote bile excretion, and then 1 to 60 min was collected every 10 min. Basic Information Specialist classification: Digestive examination classification: ultrasound Applicable gender: whether men and women apply fasting: fasting Tips: Follow the doctor's instructions when checking. Normal value There is no radioactivity in the stomach area. There is no radioactivity or a small amount of radioactivity 40~50min after drinking milk, DRGI<5%. Clinical significance Abnormal results: Most cases are the result of esophageal cancer, esophageal peptic ulcer, chronic gastritis, and gastric mucosal prolapse. People who need to be examined: people who are uncomfortable with the upper digestive tract. Precautions Contraindications before inspection: imaging advances. Requirements for inspection: Just listen to the doctor. Inspection process Duodenal reflux measurement: 99Tcm-EHIDA is infused by liver polyhedocytes and rapidly enters the duodenum with bile through the bile duct. It does not enter the stomach when it is normal. Oral milk enhances bile secretion, and there is no radioactivity in the stomach. If there is duodenogastric reflux , the radioactive area appears in the stomach area. The subject was fasted for more than 4 hours, and the examination method was the same as that of hepatobiliary. When the common bile duct and duodenum were developed, 300 ml of milk was used to promote bile excretion, and then 1 to 60 min was collected every 10 min. The duodenogastric reflux index (DGRI) was calculated using ROI technique. Not suitable for the crowd Those with normal upper digestive function. Adverse reactions and risks No related complications and hazards.
