Peptic Ulcer is categorized as "weiwan tong", "outu ", etc. in traditional Chinese medicine.

1. Symptoms: Cardinal symptom of the disease is chronic epigastralgia which is marked by dull pain or pinching pain. Sometimes it is manifested as distending pain or burning pain which often radiates to the lumbar region or the back. The pains are closely related to meals. The rule of attack in gastric ulcer is food intake ¡ú pain ¡ú remission, while in duodenal ul-cer the rule is pain ¡ú food intake ¡ú remission. The pain oc-curs periodically and is often induced by coldness, fatigue and improper food intake. The attack is frequently in winter and spring.

Other symptoms include acid regurgitation, belching, nausea and vomiting. In a few cases, perforation or bleeding may be the first clinical findings.

2. Signs: In active ulcer, there is often tenderness in the middle and upper abdominal regions. Tenderness on the left side of upper gastric region is found in gastric ulcer, while in duodenal ulcer it is found on the right side, often localized in 3-4 cm. Ulcer in the posterior wall may have pain hypersensi- tive area on the back at T11--12 level.

3. Laboratory examinations:

(1)Fecal occult blood test (OB): OB positive reaction af-ter 3-day vegetarian meals reveals that the active ulcer exists. OB positive result may turn into negative if the patient is treat-ed properly. Persistent positive reaction indicates cancerous change of ulcer or gastric carcinoma.

(2)X-ray barium examination: It is of great value. Niche is often seen in gastric ulcer. Indirect signs such as irritation and disformity of duodenal bulbar region may occur in duode-nal ulcer.

(3) Fiberscope examination: It is a main diagnostic method. Small and superficial ulcer can be seen directly. If fiberscopy is combined with biopsy, benign and cancerous changes can be differentiated. Gastric juice analysis is not used as a routine examination.
