Digestive system diseases - chapter 6 Flashcards
asymptomatic
without symptoms
gastroenterology
concerned with digestive diseases
gastroenterologist
specializes in treatment and disorders of digestions,
but does not do surgery,
does procedures (bx, endoscopic exam)
ulcer
circumscribed open sore on the skin or mucous membranes of the body,
named by part of body
(esophogeal, gastric, duodenal ulcer)
peptic ulcer
most common ulcer type that occurs in the digestive system,
stomach and duodenum,
may be in esophagus
PUD
peptic ulcer disease
PUD causes
erosion of protective membranes
caused by infection by Helicobacter pylori bacteria,
mucous is gone, acid iritates tissues
PUD risk factors
- smoking,
- chewing tobacco,
- stress,
- caffeine use,
- meds
smoking and PUD
smoking increases the harmful effects of H. Pylori,
bc alters protective mechs
and decreases blood flow,
use antacids
perforation
hole in wall lining
peritonitis
hole in wall lining
and gastric contents spill into abdominal cavity
and inflames the peritoneum
hernia
protrusion of any organ, tissue, or structure through the wall of the cavity in which it is naturally contained
inguinal hernia
in groin where ab folds meet thighs
strangulated hernia
blood supply is cut off to organ because of pressure,
can lead to necrosis and gangrene
umbilical hernia
Where
who is at risk
protrusion of part of intestine at the naval,
- obese women,
- several preg,
- congenital in infants
hernioplasty
surgical repair of a hernia, with herniorrhaphy (suture of the ab wall)
2 types of diaphragm hernias
diaphragmatic, hiatal
diaphragmatic hernia
congenital disorder
hiatal hernia
lower part of the esophagus and top of stomach slide through an opening (hiatus) in the diaphragm
into the thorax,
stomach acid backs up into the esophagus,
causes
- heartburn,
- chest pain and
- swallowing difficulty
GERD
gastroesophogeal reflux disease
hepatitis
inflammation of the liver
hepatitis causes
- toxins (alcohol),
- obstructions of the bile duct,
- metabolic disease,
- autoimmune disease,
- bacterial, viral infections
3 most common types of Hepatitis
A (infectious)
B, (serum)
C
jaundice or icterus
yellowing of the skin and sclerae of eyes,
bc liver cant remove bilirubin
the yellow compound formed when destroying erythrocytes, or when bile duct is blocked
diverticulosis
blisterlike pockets (diverticula) develop in lining of the large intestine
and may balloon through intestinal wall,
usually in sigmoid colon
diverticulitis
inflammation fot he diverticula
sx of diverticulitis
constipation,
pain in LLQ,
diarrhea,
fever,
swelling,
blood in BM,
tx= rest, antibiotics, changes in diet, sometimes surgery
gastric adenocarcinoma
neoplasm in the epithelial or mucosal lining of the stomach
signs of stomach cancer
persistent indigestion
colorectal cancer
one of the most common types of intestinal cancer in US,
in the epithelial lining of the colon or rectum,
obstruction is first sign
anorexiA
lack of appetite,
resulting in the inability to eat
(not the same as anorexia nervosa)
appendicitis
inflammation of the appendix
ascites
abnormal accumulation of fluid in the abdominal cavity, usually as a result of chronic liver disease, neoplasm, or inflammatory dis of ab
borborygmus
rumbling or gurgling noises
that are audible at a distance
and caused by passage of gas through the liquid contents of the intestine
cachexia
physical wasting that includes weight loss, loss of muscle mass,
and is commonly assoc with AIDS and cancer
aka wasting syndrome
cholelithiasis
presence of the formation of gallstones in the gallbladder
cirrhosis
scarring and dysfunction of the liver caused by chronic liver disease
Crohn Disease
aka regional enteritis
form of inflammatory bowel disease
usually of the ileum
but possibly affecting any portion of the intestinal tract
IBD
inflammatory bowel disease
dysentery
inflammation of the intestine,
especially the colon,
that may be caused by ingesting water or food containing chemical irritants, bacteria, protozoa, or prarasites
flatus
gas in the GI tract expelled from body orifice, esp anus
GERD
gastroesophogeal reflux disease
halitosis
foul smelling breath
hematemesis
vomiting of blood from bleeding in the stomach or esophagus
hemorrhoids
swollen varicose veins in the anorectal region
categorized as external or internal
intestinal obstruction
mechanical or functional blockage of the intestine that occurs when the contents of the intestine cannot move forward through the intestinal tract bc partial or complete blockage of the bowel
malabsoption syndrome
symptom complex for the small intestine
characterized by impaired passage of nutrients, minerals, or fluids through the intestinal villi into the blood or lymph
melena
dark, tarlike feces
that contain digested blood from bleeding in the esophagus or stomach
obesity
excessive accumulation of fat that exceeds the body’s skeletal and physical standards,
usually an increase of 20% or more above ideal body weight
morbid obesity
BMI is greater than 40, 100lbs overweight
obstipation
severe constipation from intestinal obstruction
oral leukoplakia
formation of white spots or patches on the mucous membrane of the tongue, lips, cheek caused primarily by irritation
pancreatitis
inflammation of the pancreas
pyloric stenosis
stricture or narrowing of the pyloric sphincter
causing obstruction that blocks the flow of food into the small intestine
regurgitation
backward flow, as in the return of solids or fluids to the mouth from the stomach
ulcerative colitis
chronic inflammatory disease of the colon,
commonly beginning in the rectum or sigmoid colon, extending upward into the entire colon
gastrointestinal endoscopy
visual exam of the GI tract using flexible fiberoptic instrument with magnifying lens and light source
to identify abnorm incl bleeding, ulceration, tumors
hepatitis panel
panel of blood tests that identifies the specific virus that is causing hepatitis
LFT’s
liver function tests
serum bilirubin
measurement of the level of bilirubin in the blood
stool culture
test to identify microorganisms or parasites present in feces that are causing a GI infect
stool guaiac
test that applies a substance called guaiac to a stool sample to detect the presence of occult (hidden) blood in the feces; also called hemoccult
(trade name is modified guaiac test)
CT
computed tomography
lower GI series
radiographic images of the rectum and colon
following the admin of barium into the rectum;
also called lower GI series or barium enema
oral cholecystogaphy (OCG)
radiographic images taken of the gallbladder
after admin of a contrast material containing iodine,
usually in the form of a tablet
upper gastrointestinal series (UGIS)
radiographic images of the esophagus, stomach, small intestine following oral admin of barium,
aka barium swallowing
anastomosis
surgical joining of 2 duct vessels or bowel segments
to allow flow from one to another
laparoscopic
minimally invasive appendectomy using 3 small abd incisions
while monitoring an enlarged image of the surgical site projected on a monitor
bariatric surgery
group of procedures that treat morbid obesity,
a cont that arises from severe accumulation of excess weight as fatty tissue, and the resultant health problems
vertical branded gastroplasty
bariatric surgery
that involves vertical stapling of the upper stomach near the esophagus to reduce it to a small pouch
and insertion of a band that restricts food consumption adn delays its passage from the pouch causing a feeling of fullness
Roux-en-Y Gastric Bypass RGB
bariatric surgery,
involving stapling the stomach to decrease the size
colostomy
surgical procedure in which a surgeon forms an opening by drawing the healthy end of the colon through an incision in the anterior ab wall and suturing it in place
lithotripsy
procedure for crushing a stone and eliminating its fragments surgically or using ultrasound waves
paracentesis
proecedure to remove fluid from the abdomen using a long thin needle inserted in through the belly (abdominocentesis)
polypectomy
excision of a polyp
nasogastric intubation
insertion of NG tube through nose into stomach to relieve gastric distention by removing gas, food or gastric secretions
antispasmodics
meds relieve cramping
laxatives
movement of material through a sluggish bowel
antacids
counteract or neutralize acidity (heartburn, reflux)
antidiarrheals
controll loose stools and relieve diarrhea by absorbing excess water in the bowel
antiemetics
control nausea and vomiting by blocking nerve impulses to the vomiting center of the brain
antispasmodics
decrease GI spasms by slowing peristalsis and motility throughout the GI tract
histamine blockers
inhibit secretion of stomach acid from the gastric cells by blocking h2 receptor
laxatives
treat constipation by increasing peristaltic activity in the large intestine or increasing water and electrolyte secretion into the bowel to induce defecation
proton pump inhibitors
supress basal and stimulated acid production by inhibing the acid pump in the gastric cells, more potent than h2 blocers
