GI system Flashcards
Crohn’s disease
Inflammatory disease of the GI tract, usually affects the ileum, leads to thickening and scarring, narrowed lumen, fistulas, ulcerations and abscesses. Usually the patient experiences remissions and exacerbations.
Diverticulitis
Inflammation of one or more diverticula from penetration of fecal matter through the thin walled diverticula resulting in formation of an abscess.
Gastric resection
Removal of the lower half of the stomach.
Melena
Black tarry stools resulting from bleeding in the upper GI tract.
Murphy’s sign
A sign of gallbladder disease consisting of pain on taking a deep breath when the examiner’s fingers are on the approximate location of the gallbladder.
Pyloroplasty
Enlarging the pylorus to prevent or decrease pyloric obstruction thereby enhancing gastric emptying.
Turner’s sign
Gray-blue discoloration of the flanks seen in acute hemorrhagic pancreatitis.
Ulcerative colitis
Ulcerative and inflammatory disease of the bowel that results in poor absorption of nutrients.
Acute ulcerative colitis results in…
Vascular congestion, hemorrhage, edema, and ulceration of the bowel mucosa.
Chronic ulcerative colitis causes….
Muscular hypertrophy, fat deposits and fibrous tissue with bowel thickening, shortening and narrowing
Vagotomy
Surgical division of the vagus nerve to eliminate the vagal impulses that stimulate hydrochloric acid secretion in the stomach.
Small intestine includes which organs?
Bile and pancreatic ducts, jejunum and ileum.
Function of the large intestine
To absorb water and eliminate waste.
Functions of the liver
- Kupffer cells remove bacteria from blood
- removes excess glucose and amino acids from blood
- synthesizes glucose, amino acids and fats
- aids in digestion of carbs, proteins and fats
- stores and filters blood
- stores vitamins A, B, D, and Iron
- secretes bile to emulsify fats
Function of the Gallbladder
Stores and concentrates bile for the digestion of fats
Pancreas - exocrine functions
- secretes sodium bicarbonate to neutralize stomach acidity
- secretes pancreatic juices containing enzymes that aid in digestion
Gastritis
Inflammation of the stomach or gastric mucosa. Monitor patient for hematemesis, tachycardia and hypotension.
Peptic Ulcer Disease
Ulceration of the mucosal wall of the stomach, pylorus, duodenum or esophagus - erosion may extend into the muscle.
Medical treatment for peptic ulcer disease
Monitor for bleeding, feed patient small bland meals, administer H-receptor agonist or PPIs, antacids, and anticholinergenics.
Total Gastrectomy
Treatment for peptic ulcer disease. Surgical removal of the stomach and attachment of the esophagus to the jejunum.
Vagotomy
Treatment for peptic ulcer disease. Surgical division of the vagus nerve to eliminate hydrochloric acid secretion into the stomach.
Gastric resection
Treatment for peptic ulcer disease. Removal of the lower half of the stomach.
Bilroth 1
Treatment for peptic ulcer disease. Partial stomach removal with attachment to the duodenum.
Bilroth 2
Treatment for peptic ulcer disease. Partial stomach removal with attachment to the jejunum.
Pyloroplasty
Surgical enlargement of the pylorus to decrease the risk of obstruction and facilitate gastric emptying.
Post-op care for surgical treatment of peptic ulcer disease.
- place patient in the Fowler position to facilitate drainage
- NPO 1-3 days until GI system is working
- Monitor patient for hemorrhage, dumping syndrome, diarrhea, hypoglycemia and vitamin B deficiency.
Duodenal Ulcers Symptoms
Having pain in the mid-epigastric area 1.5-3 hours after a meal or during the night. Melena is common and pain is usually relieved when eating food.
