Purpose:
This study is used by the Digestive Diseases Branch to evaluate patients with suspected
abnormalities in the secretion of gastric acid. The level of gastric acid is measured by
analyzing the gastric juices of each individual patient. The gastric acid sample is
obtained by a procedure known as nasogastric suctioning, where a thin plastic tube is passed
from the nose to the stomach.
Depending on the patient's present condition further diagnostic testing may be required to
achieve a diagnosis.
Study summary:
This study is an omnibus protocol used by the Digestive Diseases Branch to evaluate patients
with suspected abnormalities of gastric acid secretion. Gastric acid secretion is measured
by means of analysis of gastric juices obtained by nasogastric suction. Other clinically
indicated diagnostic procedures are performed depending on the patient's clinical state in
order to reach a diagnosis.
Criteria:
Eligibility criteria not identified in the protocol.
