For some diseases of the duodenum, such as inflammation, ulcers, polyps, and tumors of the duodenum, the main examination method is gastroscopy. Gastroscopy can clearly and accurately identify the nature and location of the specific lesions. Additionally, by taking biopsies for pathology, it can specifically determine the benign or malignant nature of the disease, which is very helpful for subsequent treatment plans.

Symptoms of duodenal ulcer

Duodenal ulcers are relatively common in clinical practice and are a frequent condition in gastroenterology. Duodenal ulcers are generally more prevalent among middle-aged individuals, with symptoms most commonly including abdominal pain, bloating, nausea, and vomiting. The abdominal pain typically manifests as upper abdominal pain, usually hunger pain which often improves after eating. It typically presents as long-term, chronic episodes over extended periods and can also occur at night as hunger pain. Therefore, for some typical patients, especially middle-aged individuals, upper abdominal pain should raise concerns about duodenal ulcers. If a patient exhibits symptoms other than abdominal pain, such as black stools, this could suggest bleeding associated with duodenal ulcers, potentially leading to black stools or even vomiting blood. Hence, it is advised that if a patient has symptoms of gastrointestinal bleeding along with abdominal pain, consideration should be given to the possibility of a bleeding duodenal ulcer. It is recommended that such patients undergo thorough gastroscopic examinations to clarify the diagnosis further.

How large does a duodenal ulcer have to be to be considered severe?

There is no specific size to determine the severity of a duodenal ulcer. However, ulcers with a diameter greater than 1.5 cm are generally considered large. In such cases, strong acid-suppressing medications are needed for treatment, along with drugs to protect the gastric mucosa. Additionally, it is necessary to test for Helicobacter pylori infection. If the infection is positive, a bismuth-containing quadruple therapy should be used for two weeks to eradicate Helicobacter pylori. The choice of specific medications, as well as their dosages and administration, should be under the guidance of a doctor.

Is duodenal ulcer bleeding a sign of cancerous change?

Duodenal ulcer bleeding does not indicate cancerous changes. The duodenal area is relatively thin, so once a duodenal ulcer occurs, it is more likely to lead to complications such as ulcer bleeding and perforation. If vomiting blood occurs with a duodenal ulcer, it indicates that the patient with the duodenal ulcer has a bleeding complication. In terms of treatment, it is first necessary to complete an endoscopic examination, which can include endoscopic hemostasis; secondly, proton pump inhibitors should be used to suppress the secretion of stomach acid and increase the pH level in the stomach; additionally, treatments that protect the stomach lining, such as aluminum hydroxide and magnesium carbonate, should be used. (Medication should be taken under the guidance of a physician.)

What medicine is taken for duodenal ulcer?

Duodenal bulb ulcer, its main cause should be related to Helicobacter pylori infection. In this case, first check for Helicobacter pylori infection, generally using the carbon-13 or carbon-14 breath test. If there is Helicobacter pylori infection, then formal antibiotic treatment is required. For example, a proton pump inhibitor combined with two antibiotics, secondly, bismuth preparations, constitute the standard quadruple therapy, with a treatment duration of 10 to 14 days. If there is no Helicobacter pylori infection, symptomatic treatment is generally sufficient. For example, suppressing stomach acid, protecting the gastric mucosa, etc. At the same time, attention should be paid to regular dietary habits, quitting smoking and alcohol, and avoiding excessive fatigue, etc. (Specific medication use should be conducted under the guidance of a doctor.)
