Duodenal and Gastric ulcer are types
of ulcers most often
seen in practice.
4. DUODENAL ULCER
4.1 Cause of duodenal ulcer is
unknown.
*
Excessive acid peptic gastric secretion is probably one of the
most importan etiolgoic factors.
*
Patients have increased
basal and maximal secretory
acid
levels.
*
There is also evidence that reduction of
duodenal buffers
(bile and pancreatic
juice) lead to
acidification and
ulceration.
4.2 CLINICAL MANIFESTATIONS
An active duodenal ulcer signals its
presence by a symptom often
described as "ulcer pain".
Pain is ofte vague located in the
midepigastrium to the right of
the midline described as a burning
pain but may be a sensation of
pressure, cramp, discomfort or hunger.
*
The pain in an active duodenal ulcer is aggravated by fasting,
thus, the patient must eat frequently.
*
Ingestion of plain water, milk or antacids give prompt
and
longer relief.
*
An important trend of this ulcer
is chronicity and seasonal
variation of symptoms.
Other
symptoms may be bleeding (Haematemesis),
gastric outflow
obstruction and perforation. These three are complications
of
ulceration.
