Test 2 Flashcards
Hiatal hernia:
protrusion of a portion of the stomach into the thoracic cavity above the diaphragms
Esophageal diverticulum:
occurs when mucosal out pouching penetrates through the muscular layer of the esophagus.
2 Types- pulsion/false
traction/true
Pyloric Stenosis:
Additive. Occurs when two muscular layers of the pylorus become hyper plastic and hypertrophic. Causes obstruction, preventing food from entering into the duodenum.
Foreign bodies:
requires two projections 90 degrees apart
Gastritis:
Inflammation of the stomach mucosa. Caused by alcohol, corrosive agents and infection
Peptic ulcer:
inflammatory process caused by a sore or hole in lining of stomach or duodenum from acid secreted by the stomach
Regional Enteritis/Crohn’s:
Additive. An idiopathic, chronic inflammatory disorder that usually involves the terminal ileum but can affect any part of the GI tract. Stress or emotional upsets can be related to the onset of the disease.
Ulcerative Colitis:
Additive. Chronic, recurrent ulceration and inflammation of colon mucosa of unknown etiology.
Intussusception:
Additive. the telescoping of one part of the intestinal tract into another bc of peristalsis. Major cause of obstruction in children.
Volvulus:
Additive or destructive. twisting of the bowel on itself that may cause obstruction. Most common sites are the cecum and the sigmoid.
Diverticulosis Vs. Diverticulitis:
Both Additive.
Osis- outpouchings that are acquired herniations of mucosa and submucosa through the muscular layersat weak points of the bowel wall.
Itis- a complication of the osis, necrosing inflammation in the diverticula.
Hirschsprung’s disease:
Additive. Lack of nerve cells in the bowel wall preventing relaxation of the colon and normal peristalsis. Congenital megacolon
Esophageal Varices:
extremely dilated sub-mucosal veins in the lower third of the esophagus. They are most often a consequence of portal hypertension, commonly due to cirrhosis
Chyme:
partially digested food mixed with gastric juices.
GERD:
Additive. a chronic digestive disease. GERD occurs when stomach acid or, stomach content flow back into your esophagus. The reflux irritates the lining of your esophagus and causes GERD.
Achalasia:
a condition in which the muscles of the lower part of the esophagus fail to relax, preventing food from passing into the stomach.
