K25.0-7/K25.9/K26.0-7/K26.9/K27.0-7/K27.9
DESCRIPTION
Ulcer in the stomach mucosa (gastric ulcer: GU) or first few centimetres of the duodenum (duodenal ulcer: DU), which penetrates into or through the muscularis mucosa.
Diagnosis is made after endoscopy, as all GUs require biopsy to exclude malignancy.
Patients with GUs and complicated DUs, those that have bled, perforated or are recurrent, must be rescoped at appropriate intervals until the ulcer has healed. H. pylori can be assessed at scope by rapid urease testing (RUT) or biopsy.
GENERAL MEASURES
Advise patient to avoid ulcerogenic medications, e.g. NSAIDs.
Advise patient to stop smoking and drinking alcohol.
Dietary advice by dietician.
MEDICINE TREATMENT
H. pylori +ve
The vast majority of GUs and DUs are associated with H. pylori infection and eradication therapy is indicated if infection is present. This will greatly reduce the rate of recurrent ulceration. Empiric eradication of H. pylori is not recommended.
Proton pump inhibitors (PPIs):
- PPI, e.g.:
- Lansoprazole, oral, 30 mg 12 hourly.
- Duodenal ulcer: for 7 days.
- Gastric ulcer: for 28 days.
- Lansoprazole, oral, 30 mg 12 hourly.
AND
H. pylori eradication: K25.0-7/K25.9/K26.0-7/K26.9/K27.0-7/K27.9 + (B96.8)
- Amoxicillin, oral, 1 g 12 hourly for 14 days.
OR
For severe penicillin allergy: (Z88.0)
- Azithromycin, oral, 500 mg daily for 3 days.
AND
- Metronidazole, oral, 400 mg 12 hourly for 14 days.
Failure of H. pylori eradication: Discuss with specialist.
H. pylori –ve
These are usually a consequence of NSAID use.
Stop NSAID until ulcer has healed.
If patient is unable to stop NSAID, refer to specialist.
- PPI, e.g.:
- Lansoprazole, oral, 60 mg daily.
- Duodenal ulcer: for 14 days.
- Gastric ulcer: for 28 days.
Resistant disease
Ulcer not healing.
High-risk patients, i.e. poor surgical risk and the elderly or concomitant disease.
Maintenance therapy :
- PPIs, e.g.:
- Lansoprazole, oral, 30 mg daily. Specialist initiated.
