Disorders of the stomach- KS's notes Flashcards
Peptic ulcer disease presents as
epigastric pain exacerbated by fasting, improved by eating
Peptic ulcer disease is a result of
H. pylori, gastric ulcer, stress gastritis, or Zollinger-Ellison syndrome
H. pylori is virtually always
associated with peptic ulcer disease
-induces acid secretion through proinflammatory cytokines
The most common cause of Gastric ulcer is
NSAID use
1/3rd are duodenal ulcers
Stress gastritis is associated with
shock, sepsis, respiratory failure, burns, hemorrhage, massive transfusions, or head injury
CNS injury, intracranial HTN, thermal injury–> particularly prevalent
Stress gastritis will cause gastric bleeding if
coagulopathy, thrombocytopenia, INR >1.5, and aPTT >2x normal
Zollinger-Ellison syndrome is a disease of the
gastroduodenal and intestinal ulceration, increased gastrin secretion and non-beta islet cell tumor of the pancreas
Zollinger-Ellison syndrome is associated with
MEN 1 (multiple endocrine neoplasia)
Complications of peptic ulcer disease include
bleeding, perforation, & obstruction
Describe the complication of bleeding in peptic ulcer disease.
hemorrhage is leading cause of death associated with PUD
SBP <100, melena, syncope/altered mentation, renal/liver/cardiac disease= significant risk factors for rebleeding
Describe the complication of perforation in peptic ulcer disease.
risk is approximately 10%
usually signaled by severe epigastric pain caused by highly acidic gastric contents into the peritoneum
Describe the complication of obstruction in peptic ulcer disease.
gastric outlet obstruction
can be acute or slow
RSI
caused by edema and inflammation in the pyloric channel and first portion of duodenum
Describe treatment of peptic ulcer disease.
antacids- -don't use in patients with chronic renal failure H2 receptor antagonists proton pump inhibitors prostaglandin analogues cytoprotective agents anticholinergics
Dumping syndrome can be
early or late
early- symptoms 15-30 minutes after a meal
late- symptoms 1-3 hours post meal- vasomotor symptoms secondary to hypoglycemia d/t excessive insulin release
Dumping syndrome is caused by entry of
hyperosmolar gastric contents into the proximal small bowel, fluid shifts into small bowel lumen
results in plasma volume contraction and acute intestinal distension
