Duodenogastric Reflux Determination and Imaging

Duodenogastric reflux measurement and imaging were used for the diagnosis and curative effect observation of reflux gastritis caused by gastric or cholecystectomy and pyloric insufficiency and the incidence and degree of reflux after different types of gastrectomy. 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: Obey the doctor's arrangements when checking. Normal value There is no radioactivity in the stomach area. There is no radioactivity or a small amount of radioactivity 40 to 50 minutes after drinking milk, DRGI <5%. Clinical significance Abnormal results: Gastroduodenal ulcer refers to the ulceration of the stomach and duodenal mucosa (ie, the inner wall). People who need to be examined: patients with chronic gastritis, residual gastritis after gastrectomy, gastric ulcer, and gastric cancer. Precautions Taboo before inspection: eating. Requirements for inspection: cooperate with a doctor. Inspection process 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 A person who does not respond to an imaging agent. Adverse reactions and risks No related complications and hazards.
