In patients with prior peptic ulcer disease, an esophagogastroduodenoscopy (EGD) with biopsy and histological studies may be performed. Also, a carbon 13 urea breath test (UBT) is helpful in these patients.

An EGD is often necessary in patients with symptoms of peptic ulcer disease in order to view the condition of the mucosal lining of the stomach and duodenum and to obtain biopsy specimens from the gastric antrum and corpus.

An echography associated with an EGD is mandatory in patients with biopsy results that are positive for gastric MALTomas in order to allow a more precise staging of the disease.
