6. Peptic ulcer diseases Flashcards
Peptic ulcer diseases defined as ?
A circumscribed ulceration of the gastrointestinal mucosa occurring in areas exposed to acid and pepsin and most often caused by Helicobacter pylori infection.
EPIDEMIOLOGY of PUD ?
- PU up to 10%.
- Duodenal ulcers 4x more common than gastric ulcer. (mainly in the duodenal cup).
- Gastric ulcers mostly in lesser curvature of the stomach.
HELICOBACTER PYLORI ?
- Most common infection in the world (20%).
- The bacterium persists in the stomach for decades in most people.
CLASSIFICATION OF PU ?
– Stomach- gastric ulcer; usually antrum lesser curvature, anterior and posteriori wall
– Duodenum- duodenal ulcer- first portion, anterior wall
– Esophagus- esophageal ulcer
– Meckel’s Diverticulum ulcer
– In the margins of a gastroenterostomy- stomal ulcer
– In the duodenum, stomach or jejunum in Zollinger- Ellision syndrome
Which classification used for PU typing ?
Modified johnson classification
Modified johnson classification ? TYPE I ?
• TYPE I ulcer along the lesser curve of stomach
Modified johnson classification ? TYPE 2 ?
• TYPE II two ulcers present- one gastric, one duodenal/ preyploric
Modified johnson classification ? TYPE 3 ?
• TYPE III prepyloric ulcer
Modified johnson classification ? TYPE 4 ?
• TYPE IV proximal gastroesophageal ulcer
Modified johnson classification ? TYPE 5 ?
• TYPE V anywhere – associated with chronić NSAID use
Manifestations of PU ?
- Episodes of remission and exacerbation.
- Pain that for duodenal ulcers is often relieved by eating or antacids.
- G.I. bleeding and possible hemorrhage (20 to 25% of patients).
- Perforation of ulcers with significant mortality.
- Obstruction of G.I. tract.
SYMPTOMS of PU?
_Pain: ”gnawing”, “aching”, or “burning”.
• Duodenal ulcers: occurs 1-3 hours after a meal and may awaken patient from sleep. Pain is relieved by food, antacids, or vomiting.
• Gastric ulcers: food may exacerbate the pain while vomiting relieves it.
#_Nausea, vomiting, belching, dyspepsia, bloating, chest discomfort, anorexia, hematemesis, &/or melena may also occur.
PUD - DIAGNOSIS ?
- Endoscopy
- Barium meal – contrast x-ray
- Biopsy – bacteria & malignancy
- H.Pylori:
▪ Endoscopy cytology.
▪ Biopsy – Special stains.
▪ Culture - difficult.
▪ Urease Breath test.
GASTROINTESTINAL BLEEDING ?
- Most common complication.
- Sudden large bleeding can be life-threating.
- It occurs when the ulcer erodes one of the blood vessels.
PERFORATION ?
- one of PUD complications.
• Perforation -> acute peritonitis: chemical -> bacterial.
• First sign is often sudden intense abdominal pain.
• Perforation of the posterior wall can also lead to pancreatitis; pain in this situation often radiates to the back.
