Barium meal(钡餐) Barium studies of the proximal gastro-intestinal tract are still commonly used as a first test for documenting an ulcer. For a DU ,it appears as a welldemarcated crater, often seen in the bulb . For a GU ,it may represent benign or malignant disease. Typically,a benign GU also appears as a discrete crater with radiating mucosal folds originating from the ulcer margin . (GU可能是良性和恶性。典型的良性表现为 游离龛影,粘膜皱襞从溃疡边缘向内放射集 中)

How many types can the peptic ulcer be classified? What are they?
Etiology
1、 H.pylori infection: the main cause of peptic ulcer. 2、 Gastric acid and pepsin :PU is due to gastric acid and pepsin consisting gastric juice caused by their own digestion. 3、 Drug factors : some NSAIDs, anticancer drugs have damaging effects on gastric and duodenal mucosa, which was most obvious in NSAIDs. NSAIDs in addition to direct effects on the gastric and duodenal mucosa caused the damage, mainly through the inhibition of prostaglandin synthesis.
Clinical Features
symptom——Abdominal Pain 1、Long term :several years or even decades. 2、Periodical(周期性的) attack: the attack and relieved stage appear alternately.发作期与缓解期交替出现 3、Rhythmic epigastric pain.节律性上腹疼 GU · irregular gastric pain after meal · Ingestion of food and antacids(制酸剂) can not relieve pain DU · Burning pain worse when hungry or at night · Ingestion of food and antacids often relieve pain

Peptic ulcer(PU):Mainly refers to the chronic ulcer occurs in the stomach and duodenum mucosa (n. [解剖] 粘膜), namely, gastric ulcer (GU) and duodenal ulcer (DU). The basic formation of ulcer is the gastric acid and pepsin (n. [医]胃蛋白酶) digestion . Clinically DU is more common than GU with the ratio being about 3:1.DU occurs in young adults.The age of onset of GU is generally 10 years older than DU. Autumn, winter and spring are the seasons of PU.
