Peptic ulcer disease Peptic ulcer disease --
Is recurrent disease, the main feature of which is Is recurrent disease, the main feature of which is the formation of defects (ulcers) of the stomach the formation of defects (ulcers) of the stomach
mucosa and / or duodenal mucosa, which mucosa and / or duodenal mucosa, which penetrates to mucosal layer, submucosa and penetrates to mucosal layer, submucosa and
deeper, unlike erosiondeeper, unlike erosion
Definition
Ulcers may range in size from several millimeters to several centimeters.
Ulcers are delineated from erosions by the depth of penetration; erosions are more superficial and do not involve the muscularis mucosae.

It causes It causes 9090-96-96% % of duodenal ulcers and of duodenal ulcers and 70-80% of gastric ulcers.70-80% of gastric ulcers.
Etiology:Helicobacter pylori infection.
Hyperacidity - eg. zollinger ellison.
Drugs - anti-inflammatory (NSAIDs) & Corticostroids.
Cigarette smoking, Alcohol,
Rapid gastric emptying
Personality and stress
Helicobacter pylori:Most common infection in the world (20%)
10% of men, 4% women develop PUD *
Positive in 70-100% of PUD patients.
H.pylori related disorders:– Chronic gastritis – 90%– Peptic ulcer disease – 95-100%– Gastric carcinoma – 70%– Gastric lymphoma– Reflux Oesophagitis.– Non ulcer dyspepsia
NSAIDSAspirin and other non steroidal anti
inflammatory agents damage the gastric mucosal barrier and are an important etiologic factor in 30% cases of gastric ulcer.
PATHOGENESISPATHOGENESIS
ClassificationI. Phase of disease:-Acute-Uncomplete remission-Remission
II. Course of disease: -mild-moderate- severe.
III. Localization: -stomach-duodenum-stomach + duodenum-gastroeneroanostomosis
IV. Association with Helicibacter pylori:- H. pylori – associated- H. pylori – not associated
V. Complications-Hemorrhage-Perforation -Penetration-Pyloristenosis-Malignancy
Example of diagnosis
Peptic ulcer disease,
acute phase,
mild course,
active ulcer of duodenum,
H. pylori – associated.

CLINICAL FEATURESCLINICAL FEATURES
PAINPAINSite: Site:
EpigastriumEpigastrium
Mendel’s symptom Mendel’s symptom “+”“+”
Character: Burning in character
Radiation: Pain is localised and patient is able to point it with his one finger "pointing sign". If pain is radiating to the back in inter scapular region and not responding to antacids or other anti-ulcer drug, suggests posterior penetration of ulcer into the pancreas.
Time of pain:Soon after eating within 15-30 minutes in gastric ulcer while 2-3 hours after eating in duodenal ulcer that frequently awakens the patient at night.
Relation with food:Patient with gastric ulcer are afraid to eat because it causes pain due to release of acid in response to food. Patients with duodenal ulcer feel pain in empty stomach and get relief after taking food which causes partial neutralization of acid. Then in response to food there is increased acid secretion which causes pain after 2-3 hours. Acid induced pain is believed due to acid stimulation of chemical receptors.
Endoscopy:
Endoscopy is the procedure of choice for diagnosis of peptic ulcer
All patients with gastric ulcer require biopsy initially and the follow up endoscopy and biopsy after 6 weeks of starting therapy, to confirm that the ulcer has healed.

Histology
H. pylori can be detected histologically on biopsy of gastric mucosa obtained at endoscopy and stained with haematoxylin and eosin.

Urea breath test with I3C
This is a quick and easy way of detecting the presence of H. pylori by urease production with release of labelled CO2 detected on a mass spectrometer.
This test indicates active infection but is expensive.
