chapter 40 part 2 Flashcards
peptic ulcer disease may be referred to as a
gastric ulcer
duodenal ulcer
esophageal ulcer
excavation (hollowed-out area) that forms in the mucosa of the stomach, in the pylorus, duodenum, or in esophagus
peptic ulcer disease
peptic ulcer more likely to occur in the _____ than in the stomach
duodenum
occur as a result of the BACKWARD FLOW of HCl from the stomach into the esophagus
ESOPHAGUS ULCER
Most peptic ulcers result from infection with _______
H. pylori
major risk factor for peptic ulcers
nsaids
what blood type is the more susceptible to the development of peptic ulcers
type O
the opening between the stomach and duodenum
pylorus
the first portion of the small intestine, between the stomach and the jejunum
duodenum
thin membrane that ‘lines the inside of the wall of the abdomen’
peritoneum
a rare condition in which ‘benign or malignant tumors form in the pancreas and duodenum’ that secrete excessive amounts of the hormone gastrin
zollinger-ellison syndrome
acute mucosal ‘ulceration of the duodenal or gastric area that occurs after physiologically stressful events’, such as burns, shock, sepsis, and multiple organ dysfunction syndrome
stress ulcer
specific TYPES of ulcers that result from STRESSFUL conditions include:
curling ulcer
cushing ulcer
a type of stress ulcer: observed after extensive BURN INJURIES and often involves the antrum of the stomach or the duodenum
curling ulcer
a type of stress ulcer: common in patients with a traumatic head injury, stroke, brain tumor, or following intracranial surgery; caused by ↑ICP
cushing ulcer
in peptic ulcer, pain occurs immediately after eating, what is the estimated hours?
(2-3 hours)
common when the patient’s stomach is empty
sour eructation/burping
allows direct visualization of inflammatory changes, ulcers, and lesions
preferred diagnostic for peptic ulcer
upper endoscopy
used to determine the extent of blood loss
CBC
lack of HCl
achloryhdria
low levels of HCl
hypochlorhydria
high levels of HCl
hyperchlorhydria
recommended days for combination drug therapy
10 to 14 days
what foods to be avoid in peptic ulcer
foods in high temp
alcohol
coffee
the two most common causes of upper GI tract bleeding
gastritis
hemorrhage
EROSION OF THE ULCER through the gastric serosa INTO THE PERITONEAL CAVITY without warning; abdominal emergency
PERFORATION
EROSION OF THE ULCER through the gastric serosa INTO ADJACENT STRUCTURES such as the pancreas, biliary tract, or gastrohepatic omentum
PENETRATION
occurs when the area distal to the ‘pyloric sphincter becomes scarred and stenose’
GASTRIC OUTLET OBSTRUCTION
