How is Malignant Gastric Ulcer Diagnosed?
Diagnosis and Treatment of Malignant Gastric Ulcer
The methods for confirming the diagnosis of a malignant gastric ulcer primarily encompass clinical symptoms, physical examination, laboratory tests, and imaging studies. Should patients exhibit the aforementioned symptoms, it is recommended to promptly seek medical attention and undergo targeted treatment under the guidance of a physician.
I. Clinical Symptoms
Early-stage malignant gastric ulcers typically manifest without pronounced discomfort. However, as the condition progresses, upper abdominal pain may emerge, accompanied by symptoms such as anorexia, nausea, and vomiting. In severe cases, this may culminate in vomiting blood or the presence of blood in stool.
II. Physical Examination
Patients with malignant gastric ulcers often exhibit weight loss, anemia, and malnutrition. Additionally, the presence of tumor tissue can irritate local areas, triggering abdominal pain.
III. Laboratory Tests
- Helicobacter Pylori Testing: If Helicobacter pylori infection is suspected, relevant tests should be conducted for definitive diagnosis.
- C13 Breath Test: This test assesses the presence of Helicobacter pylori, serving as a commonly used method. A normal result is 0-4 dpm; values exceeding 4 dpm suggest possible infection.
- Fecal Occult Blood Test: The detection of red and white blood cells in stool indicates potential gastrointestinal bleeding.
- Gastroscopy: This examination enables observation of gastric mucosal erosion or ulceration, and pathological biopsy can be performed to ascertain malignancy.
IV. Imaging Studies
Imaging modalities, including X-ray barium meal radiography, CT scans, and endoscopic ultrasonography, aid in ruling out other diseases like liver and pancreatic cancer. Furthermore, a whole-body bone marrow aspiration may be performed to determine the presence of metastatic lesions.
Upon confirmation of a malignant gastric ulcer, patients must actively cooperate with their physicians in treatment to prevent disease progression. Daily dietary habits should prioritize light, easily digestible foods, avoiding spicy or irritating foods.
