Diagnosis
The diagnosis of Helicobacter pylori can be by:
- Breath testing (does not require EGD);
- Direct culture from an EGD biopsy specimen;
- Direct detection of urease activity in a biopsy specimen;
- Measurement of antibody levels in blood (does not require EGD). It is still somewhat controversial whether a positive antibody without EGD is enough to warrant eradication therapy.
The possibility of other causes of ulcers, notably malignancy (gastric cancer) needs to be kept in mind. This is especially true in ulcers of the greater (large) curvature of the stomach; most are also a consequence of chronic H. pylori infection.
Differential Diagnosis
Treatment
Younger patients with ulcer-like symptoms are often treated with antacids or H2 antagonists before EGD is undertaken. Bismuth compounds may actually reduce or even clear organisms.
Patients who are taking nonsteroidal anti-inflammatories (NSAIDs) may also be prescribed a prostaglandin analogue (Misoprostol) in order to help prevent peptic ulcers, which may be a side-effect of the NSAIDs.
When H. pylori infection is present, the most effective treatments are combinations of 2 antibiotics (e.g. Erythromycin, Ampicillin, Amoxicillin, Tetracycline, Metronidazole) and 1 proton pump inhibitor (PPI). An effective combination would be Amoxicillin + Metronidazole + Pantoprazole (a PPI). In the absence of H. pylori, long-term higher dose PPIs are often used.
Treatment of H. pylori usually leads to clearing of infection, relief of symptoms and eventual healing of ulcers. Recurrence of infection can occur and retreatment may be required, if necessary with other antibiotics. Since the widespread use of PPI's in the 1990s, surgical procedures (like "highly selective vagotomy") for uncomplicated peptic ulcers became obsolete.
Perforated peptic ulcer is a surgical emergency and requires surgical repair of the perforation. Most bleeding ulcers require endoscopy urgently to stop bleeding with cauterizations or injection.
Complications
- Gastrointestinal bleeding is the commonest complication. Sudden large bleeding can be life threatening[1]. It occurs when the ulcer erodes one of the blood vessels.
- Perforation (a hole in the wall) often leads to catastrophic consequences. Erosion of the gastro-intestinal wall by the ulcer leads to spillage of stomach or intestinal content into abdominal cavity. Perforation at the anterior surface of stomach leads to acute peritonitis, initially chemical and later bacterial peritonitis. Often first sign is sudden intense abdominal pain. Posterior wall perforation leads to pancreatitis; pain in this situation often radiates to back.
- Penetration is when the ulcer continues into adjacent organs such as liver and pancreas[2].
- Scarring and swelling due to ulcers causes narrowing in the duodenum and gastric outlet obstruction. Patient often presents with severe vomiting.
