duodenal ulcer

A duodenal ulcer is a type of peptic ulcer that occurs in the lining of the duodenum, which is the first part of the small intestine. It is a sore that forms in this area due to various factors.

Causes and Symptoms

• A duodenal ulcer is usually caused by an infection with Helicobacter pylori (H. pylori) bacteria [1].
• The most common symptom of a duodenal ulcer is a dull or burning pain in the upper abdomen, between the breastbone and the navel [2].
• This pain often occurs between meals and can be relieved by eating or taking antacids.

Types and Prevalence

• Duodenal ulcers are a type of peptic ulcer disease (PUD) that affects about 1% of the population worldwide [5].
• PUD causes open sores in the stomach lining or duodenum, leading to symptoms like burning or gnawing stomach pain [6].

Treatment and Prevention

• A 4-8 week course of acid-suppressing medications can help treat H. pylori infections and prevent ulcers from forming [3].
• Lifestyle changes, such as maintaining a healthy diet and avoiding smoking, can also help prevent duodenal ulcers.

Common symptoms of a duodenal ulcer include:

• Stomach pain which sometimes becomes more severe and then gets better depending on what you are eating and drinking [7]
• Pain in the upper tummy (abdomen) just below the breastbone (sternum) is the common symptom. It usually comes and goes [8]

Other possible symptoms:

• Bloating
• Feeling sick
• Eating food might help, but some foods can make it worse [2]
• Vomiting blood, which may appear red or black, and having dark blood in stools, or stools that are black or tarry [3]

Important notes:

• The most common symptom of a stomach ulcer is a burning or gnawing pain in the centre of the tummy (abdomen), but this can also be a duodenal ulcer symptom [5]
• Symptoms include burning or gnawing stomach pain, and treatment is with medications, unless you have complications like bleeding [4]

Diagnostic Tests for Duodenal Ulcer

Duodenal ulcers are a common cause of abdominal pain, and various diagnostic tests can help confirm the presence of this condition. Here are some of the key tests used to diagnose duodenal ulcers:

• Upper Gastrointestinal (GI) Endoscopy: This is the preferred diagnostic test for evaluating patients with suspected peptic ulcer disease, including duodenal ulcers [4]. During an endoscopy, a thin, flexible tube with a camera and light on the end is inserted through the mouth to visualize the inside of the stomach and duodenum.
• Gastroscopy: This test involves passing a thin, flexible tube with a camera and light on the end through the mouth to directly look inside the stomach and see if there are any ulcers [6].
• Blood Tests: Blood tests can check for infection-fighting cells (antibodies) that indicate the presence of H. pylori bacteria, which is often associated with duodenal ulcers [3].
• Stool Antigen Test: This test checks for the presence of H. pylori bacteria in the stool.
• Computed Tomography (CT) Scanning: While CT scanning plays a small role in the primary detection of duodenal ulcers, it can be used to rule out other conditions that may cause similar symptoms [7].

Additional Tests

In some cases, additional tests may be necessary to confirm the diagnosis or rule out other conditions. These may include:

• Esophagogastroduodenoscopy (EGD): This test is a specific endoscopy exam to diagnose peptic ulcer disease and can identify the location and size of the ulcer [2].
• Imaging Tests: Imaging tests such as CT scanning or ultrasound may be used to rule out other conditions that may cause similar symptoms.

It's essential to note that a diagnosis of duodenal ulcers should only be made by a qualified healthcare professional after a thorough medical history, physical examination, and diagnostic testing.

Treatment Options for Duodenal Ulcer

Duodenal ulcers are typically treated with a combination of medications to reduce gastric acid and help protect and repair the tissues in the duodenum.

• Proton Pump Inhibitors (PPIs): The most commonly used medicine is a PPI, such as omeprazole or lansoprazole, which reduces the amount of acid in your stomach. This helps to heal the ulcer and prevent further damage [8].
• Antacids: Antacids can be used to neutralize stomach acid and provide quick relief from symptoms. However, they are not a long-term solution for treating duodenal ulcers [9].
• Combination Therapy: First-line treatment for peptic ulcer disease is a combination of medications to reduce gastric acid and help protect and repair your tissues. This may include a PPI, antacids, and other medications to coat the ulcers and promote healing [4].

Antibiotics

In some cases, antibiotics are used to treat duodenal ulcers caused by H. pylori bacteria. The most commonly used antibiotics for this purpose are amoxicillin, clarithromycin, and metronidazole. These medications can help kill the bacteria and promote healing of the ulcer [5].

Side Effects

The side effects of these antibiotics are usually mild and may include:

• Diarrhea
• Nausea
• Vomiting
• Abdominal pain

It's essential to follow your doctor's instructions carefully and report any side effects promptly.

Differential Diagnosis of Duodenal Ulcer

Duodenal ulcers can be challenging to diagnose, and a thorough differential diagnosis is essential to rule out other conditions that may present with similar symptoms. Here are some alternative diagnoses to consider:

• Functional Dyspepsia: This condition involves recurring upper abdominal discomfort or pain without any obvious cause (see [4]). It's often considered in cases where the duodenal ulcer diagnosis is uncertain.
• Gastric Cancer: Although rare, gastric cancer can present with similar symptoms to duodenal ulcers, such as abdominal pain and weight loss (see [5]).
• Outlet Obstruction due to Stricture Formation: This condition involves a narrowing of the duodenum, which can cause symptoms similar to those of a duodenal ulcer (see [4]).
• Acalculous Cholecystitis: Inflammation of the gallbladder without any visible stones can present with abdominal pain and fever, making it a differential diagnosis for duodenal ulcers (see [7]).
• Acute Cholecystitis: Inflammation of the gallbladder due to infection or obstruction can cause similar symptoms to duodenal ulcers (see [7]).
• Cholelithiasis: Gallstones can cause abdominal pain and discomfort, which may be mistaken for a duodenal ulcer (see [7]).
• Crohn Disease: This inflammatory bowel disease can affect the small intestine, including the duodenum, and present with symptoms similar to those of a duodenal ulcer (see [7]).

It's essential to consider these alternative diagnoses when evaluating patients with suspected duodenal ulcers. A thorough medical history, physical examination, and diagnostic tests such as endoscopy or imaging studies can help differentiate between these conditions.
