GI diseases pt 2 Flashcards
how do diseases of intestines manifest?
diarrhea
constipation
changes in stool characteristics
secondary diseases that arise as a result of poor nutrition
What is appendicitis?
acute and painful inflammation of the appendix
most common in males before puberty to age 25
location of appendix at cecum makes it a trap for fecal material which contains bacteria (particularly Escherichia coli)
s/s of appendicitis?
appendix to become swollen, red and covered with inflammatory exudate
possible to develop gangrene (become green and black)
walls of appendix may thin and rupture causing fecal material to spill into peritoneal cavity = peritonitis
nausea, vomiting, fever of btwn 99F and 102F and elevated WBC count
how to diagnose appendicitis?
physical exam (pain begin in mid abd and shifting to the RLQ)
pt may walk or lie bending over and draw R leg up to abd to seek pain relief
What is malabsorption syndrome?
inability to absorb fat or other substance from the small intestines
main cuase is defective mucosal cells in small intestine (also hindered if intestinal enzymes and chemicals r not propelry assisting digestive process), disease pancres or blocked pancreaticduct, reduced secretion of bile (caused by hepatic disease or bile duct obsrtuction), also prevents lipid digestion, hyperparathyroid and diabetes mellitus, severe parasitic and worm infestiaions
often occurs with other types of diseases and disorders
diseased pancreas + malabsorption syndrome
disease pancreas/ obstructed pancreatic duct deprives small intestine of lipase and amylase = fat cant be digested or absorbed
s/s of malabsorption syndrome?
bleeding bc vitamin K essential to blood clotting cant be absorbed
lack of energy
inability to maintain weight
fat in stool (fatty, pale stool with a foul odor, stool floats)
abd discomfort
bloating with gas
chronic diarrhea
abnormal bowel movement
anemia
SOB
how to diagnose treat malabsorption?
diagnose w/ several blood tests, lab analysis of stool samples, biopsy of small bowel
treat - depends on cause, diet is carefully controlled and supplements of fat-soluble vitamins A, D, E and K and high-protein, high cal
What is Celiac disease + other names?
aka gluten enteropathy and celiac sprue
disease of small intestine, characterized by malabsorption, gluten intolerance, damage to lining of intestine
affects 2 million ppl or 1 in 133 ppl
caused by toxic or an immunologic reaction to component of gluten, genetic, 2x more in females

fkatulence
abd distention
intestinal bleeding
weakness
muscle wasting
large, pale, greasy, foul-smelling stools
how to diagnose and treat celiac disease?
diagnose - positive serologic testing, biopsy of small intestine showing changes or destruction in mucosal lining ((atrophy and flattening of intestinal villi), improvement while on a gluten-free diet, blood tests for WBC, platelets, albumin, PT, glucose tolerance, upper GI and small bowel radiographic studies
treatment - elimination of gluten from diet, fluid replacement and vitamin supplements, corticosteroids for refractory sprue
What are Diverticula + etiology & s/s?
little pouches or sacs formed when the mucosal lining pushes through the underlying muscle layer of the intestinal wall (called diverticulosis) which become diverticulitis when these acs become impacted fecal material and bacteria and become inflamed
- colonic diverticla may vary in size, from a few mm to several centimeters and in number from 1 to several dozen
- sometimes pt expresses nonspecific bd distress, such as pain and flatulence, difficulty in defacation, alternating constipation and diarrhea and even blood in stool
- cause is unknown, thought to be caused by diet that contains inadequate roughage and excessive amounts of highly refined food (lack of roughage = small-caliber, drier stools)

2-3 times more common among Ashkenazi Jews
family history
autoimmune disease
s/s of crohn’s disease?
- peroianal fissures and fistulas
- related to the inflammation
- intestinal walls become thick and rigid
- lumen narrows and develops a chronic obstruction
- resembles appendicitis
- malaise, fever, abd fullness, blood in stool
- crappy, intermittent abdominal ain, often in RLQ abdomen
severe diarrhea, constipation and melena - anorexia, nausea and vomiting leading to wt loss
- inflammation can manifest as RA, hemorrhage or perforation
- complications include deep ulcerations, symptoms of bowel obstruction, adhesions, abscesses, mimin small intestine bacterial overgrowth (SIBO)

diagnose - CT, endoscopy, enteroscopy, test for elevated level of WBC, low levels of potassium, calcium and magnesium, biopsy
treat - anti-inflammatory meds and immunosuppressive agents, antibioitcs, sterois, anticholinergics, narcotics, surgery to correct complications like obstruction, perforation or massive hemorrhage (may need ileostomy), dietary supplements of vitamins, minerals, proteins and calories, iv nutrition
What is chronic ulcerative colitis + etiology?
type of chronic inflammatory bowel disease that affects mucosa and submucosa of rectum and colon
serious inflammation of the colon characterized by extensive ulceration of the colon and rectum

how to treat chronic ulcerative colitis?
aimed to reduce symptoms, rpelace nutruents, stop blood loss and prevent complications
reducing stress, eliminate triggering food (low in fat and bulk and high in protein, vitamins and calories), adrenal corticosteroids (prednisone and hydrocortisone for autoimmunity), anticholinergic drugs, Anti-TNF (antibodeis to TNF)
colostomy, preoctocolectomy (surgery to remove colon and rectum) followed by ileostomy or ileoanal anastomosis

how to remove organic obstruction?
suction tube or surgery
what is strangulated hernia obstruction?
protrusion of intestine through abd wall, surgery is needed because strangulated segment can become gangreous
what is a paralytic obstruction?
results from peritonitis
if a loop of small intestine is surrounded by pus from infection smooth muscle cant contract so sphincters can go into spams and fail ot open bc of intense pain

bleeding, hemorrhoid to proplase (come through anal opening)
when do hemorrhoids frequently occur?
during pregnancy bc of pressure from an enlarged uterus
diagnose and treatment of hemorrhoids?
diagnose - visual insepciton of anal area, proctoscopy, low Hgb and RBC count
treat - adding fiber and water to diet, stool softeners to reduce straining and subsequent inflammation, may take medicated suppositories and anorectal creams for pain and reduce inflammation, warm sitz baths along with topical anesthetic ointment or witch hazel compresses, sclerotherapy injections to induce scar formation, band ligation, cryosurgery, photocoagulation, electrocoagulation, thermocoagulation, stapled hemorrhoidectomy

dysentery
risk factors for dysentery?
poor sanitation, being under 6 over age 65, having immune deficiency
What is Entamoeba histolytica?
transmitted in feces-contaminated food and water, causes amebiasis (amoebic dysentery)
invades wall of colon and causes numerous ulceration, which account for the pus and blood in the stools

What is diarrhea?
unformed watery stool that is result of contents of smal intestine rushe through large intestine
mild or severe, acute or chronic
cause dehydraton and electrolyre imbalanace
severe or prolonged diarrhea can produce metabolic acidosis
pt may be lethargic and may hyperventilaite
s.s include intestinal cramping, wakenss, nausea, irritabilty and fever
stool passage may become painful
sign not disease
large intestine cant reabsrob water from feces bc peristalsis in intestine is intensified
What impairs water absorption by mucosal cells?
intestinal infections and food poisoning
What is constipation?
inability to eliminate feces from color and feces become hard and dry
caused by poor habits of elimination, dehydration, low-fiber diets
what happens if defecation doesnt occur when defaction relexes r strong?
feces remain too long in colon , excess water reabsoprtion - feces become dry, making elimination difficult
What does it mean if blood in stool is bright red?
bleeding from distal end of colon (rectum)
may indicate bleeding hemorrhoids
can indicate cancer of rectum

What provides temp protections agaisnt hepatitis virus A?
Immunoglobulin injections
What is hepatitis virus B + diagnose and treat?
aka serum hepatitis
more serious and common disease
1.25 milllion american r chronically infected with hepatitis B (25% will die from cirrhosis)
aminotransferase levels r higher than in HAV infection, liver inflammation causes destruction of liver cells and necrosis, abnormal results of liver profile studies
sudden onset and progresses rapidly
delirium is followed by coma and death
diagnose with detection of hepatitis B surface antigen in blood (if in blood for over 6 months, chronic)
treat with oral antiviral therpay in chronic, usually general medical managemetn as it is self-limiting, interferon, hepatitis B Ig
How is heptatis virus B spread?
donating blood, serum transfusions that contain virus, sexual transmission, sharing contaminated needles or syringes
What is hepatitis C + s/s and diagnose?
- leading viral cuase of chronic liver disease and cirrhosis
- most common reason for liver transplants and bloodborne infection
- incubation period varies from 2 weeks to 6 months
- s/s resemble hepatitis A, less severe and sometimes without jaundice, results in radual, insidious liver disease, necrosis, fibrosis, and cirrhosis
- 4+ million Americans have Hep C currently
- diagnose with ultrasonography of liver, lab findings include elevated serum levels of liver enzymes, elevated serum bilirubin, bilirubinuria, circuliating virus in blood (HCV ribonucleid acid serum test) + postivie blood test result for presence of anti-HCV antibodies
About __% of those infected with hepatitis C
develop cirrhosis, and a number of these cases
can lead to end-stage liver disease
20

12th leading cause of death in US (kills abt 26k yrly)
alc cirrhosis is most common (other causes r malnutriotion, hepatitis, paraxsites, toxic chemicals, CHF, Wilson disease, hemochromatosis)
other names for alc cirrhosis?
portal, Laennec, or fatty nutritional
cirrhosis (an accumulation of fat often develops
within the liver)
What occurs to a cirrhotic liver?
loses highly organized arrangement of cells, bv and bile ducts
liver cells r repalced by fibrous connective tissue and scar tissue (no liver cell function)
liver starts enlarged due to regenration but becomes smaller as the fibrous connective tusse
has nodular appearance (hobnailed liver)
What happens to rest of abd due to cirrhosis?
high bp in vessels of abd and other areas
esophageal veins swell = esophageal varices
spleen, pancrease and sotmach swell
these organs and vessels may hemorrhage
may lead to hematemesis
what is a characterisistic symptom (among others) of cirrhosis?
distention of abd caused by accumulation of fluid in the peritoneal cavity (fluid is called ascites, develops as a result of liver failure)
pressure in obstructed veins forces plasma into abd cavity
at first smypomt r vague and mild (pt experiences loss of appetite and wt, nausea and vomiting, indigestion, edema, tend to bruise and bleed more easily, frequently nosebleed, skin appears jaundiced and dry with pruritus, small, red, spidery marks on face and body, testicular atrophy, gunectomastia, loss of chest hair in male), impaired memory, confusion and droswiness
What does the disorganization of the liver due to cirrhosis cause?
blackage of the bile ducts
= bile in blood = jaundice bc bile is not secreted in duodenum = clay colored stool and dark color to urine
impact of cirrhosis on men?
liver inactivates estrogen produces in adrenal glands but if liver doesnt do that then men have feminizing effect, boobies enlargen (gynecomastia), palms become red, hair on chest is lost, female type distribtion of hair, atrophy of testicles
effect of cirrhosis on blood?
liver cant detoxify so ammonia and poisonous substance in blood
what can elevated ammonia cause
neurological disorders (confusion, disorientation, stupor, asterixis, abn sleeiness and hepatic coma)
other causes for cirrhosis?
severe chronic hepatitis, chronic inflammation of bile ducts, certain drugs and toxins that = necrosis of lier cells r first step in developing cirrhosis
diagnose and treatment for cirrhosis?
diagnose - physical exam (liver appears enlarged, firm to hard, palpable blunt edge, abd radiographs show enlargement, blood studies for elevated liver enzyme and bilirubin levels, CT, ultrasonography needle biopsy) cant reverse liver damage but can try preventing further damage by treating alcoholism or liver infection
treat - symptoms, ex: treat edem with diuretics, portal hypertension is fixed with beta blockers to reduce bp, vitamin and mineral supplements, anaticds, diuretics (prevents edema, ascites), paracentesis, only solution is liver transplant
What is hepatocarcinoma + demographics and etiology?

secondary that metasised from ther orgnas, esp colon, rectum, sotomahc, pancreas, esophagus, lungs or breat
causes for liver cancer
primary - viral hepatitis and cirrhosis, HBV, exposure to aflaxtoxins, mostly in Africa and Asia
other causes r aflatoxin (toxin from mold that grow on peanuts and rice)
s/s of hepatocarcinoma?
depends on site of tumor
if in portal vein ascites in abd cavity + cirrhosis
if fluid has blood than malignancy
tumor blocking bile duct = jaundice
wt loss, abd mass, pain in RUQ
early satiety, upper abd pain
thrombocytopenia, elevated bilirubin, low albumin, electrolyte abnormalities
elevated serum alphafetoprotein (AFP), protein secreted by neopalstic liver cells

serum levels of enzymes that arise from diseases liver tissue, mainly needle biopsy or open biopsy, AFP level greater than 500 g/L, ultrasonographym CT, MRI, liver biopsy (risky in pt with cirrhosis)
prognosis is poor
treat - surgical resection (partial hepatectomy), radiofrequency ablation, percutaneous ethanol injection
What is cholelithiasis + s/s and etiolgy
?
aka gallstones
precipitated bile components in gallbladder and bile ducts
stones r created when bile composition changes, gallblader msucle activity reduces, pregnancy , use of oral contraceptives, diabetes mellitus, obesity, cirrhosis and pancreatitis, high cal, high cholesterol diet, ileal disease, alcohol cirrhosis
asymptomtic until bile ducts become obstucutred by stones, cockly pain (or biliary colic) signal obstruction, pain in epigastric or RUP, oten radiation ot right upper back in area of scapula, N^V, typically severe pain, flatulence, clay-colored stool jaundice (transient elevations of bilirubin and alkaline phosphate, AST, and ALT)

guardig URQ muscles
shallw respiration
jaundice
clay-colored stools
dark urine
pruritius
ruptured gallbladder
why pain with cholecystitis?
when eating fat duodenum stimulates gallbaldder to contract = pain (prolonged inflammation = walls of gallbladder to contract = pain)
complications of cholecystits?
lack of blood flow bc of obstruction = swelling = infarction = gangrene (may need surgical removal)
what is biliary cirrhosis?
necrosis and fibrosis of lvier cells lining bile ducts when bile accumuilates in the bile ducts in the liver
What is acute pancreatitis + etiology?
serious, painful inflammation of the pancreas
more prevanelnt nin women and usually occurs after 40
thought to be caused by “escape” of activated pancreatic enzymes from acinar cells into surrounding tissue (could be cause by alcholism, biliary tract disease, trauma, infection, structural anomalies, greatly elevated calcium level in blood, hemorrhage, hyperlipidemia, drug may cause pancreatic, gallstones)
What is pancreatitis associated with in men and women (seperately)?
men - associated with alcoholism or perptic ulcers (v. poor prognosis)
women - gallbladdder disease (good prognosis)
s/s pancreatitis?

sudden severe, steady abd pain (back and resembles sharp pain of perforated ulcer)
N&V
epigastric pain is often worsened by walkign and lying supine or improved by sitting and leaning forward
acutely ill, diaphoretic, tachycardic with shallow, rapid respirations (B{ falls and body temp rises)
Jaundice (if swelling blocks common bile duct)
greasy stool with foul odor(no lipid enzymes from pancrease)
secondary malabsorption syndrome

ANOREXIA
constipation
flatulence
weight loss
organ becomes fibrotic
signs of malabsorption and diabetes mellitus

treatment - hospitalization, few days of fasting, IV fluids, analgesics, no smoking, drinking alc and good hydration, pain meds (usually narcotic), monitor electrolytes, serum amylase and lipase, Hct, glucose and serum calcium
What is cancer of the pancreas`?
adenocarcinoma
more frequent in males btwn 35-70
malignancy in head of pancrease can block common bile duct (=jaundince and impaired digestion = malabsorption of fat and clay-colored stool, sufficient nutrients and cal and wt loss, great pain)
can get v. advanced before discovered
most of neoplasms arise from exocrine cells of pancreas wherease 1-2% involve endocrine cells
risk factors for adenocarcinoma?
cigarette smoking
high-protein and -fat diets
food additives
exposure to industrial chemicals such as
beta-naphthalene, benzidine, and urea
Chronic alcohol abuse
chronic pancreatitis
diabetes mellitus
obesity
mutations in cancer susceptibilty genes BRCA1, BRCA2 and STK11
how to diagnose and treat adenocarcinoma?
diagnose - laparoscopic biopsy and ultrasound, CT, dilated bile ducts, mass in pancreas, CA 19-9 serum tumor marker, tissue diagnosis by EUS fine-needle aspiration biopsy of mass and lymph nodes, staging laparoscopy (bc of location pancreas is inaccessible to palpation and insensitive to many diagnstic techniques)
treatment - prognosis is poor so death is relatively short, treatment is surgerical resection (only viable for pt with disease confined to pancreas and peripancreatic nodes) (only 15-20% of pt are canddates for surgery), stents, control of pain and treatment of depression, weight loss, malabsorption, chemo and radia,tionation
Age related sdiseases of mouth and esophagus?
dental caries (cavities) r more prevalent in children
as you get older risk for gingivitis and periodontal disease increase
periodontal disease and osteoporosis = tooth loos in older adults
number of taste buds, saliva secretion lessen = decreased appetitie

diverticula is most common in older adults
intestinal motility is slsightly decreased
Age related sdiseases of liver and gallbladder?
uncommon in children
in adulthood liver function diminsished w/ increasing age = persistence of high blood lvels of med or toxins, levels of clotting factors decline, cholelithiasis is highest in those over 80
Age related sdiseases of pancreas?
pancreatic disorder r uncommon in children except for Type 1 diabetes
type 2 (known as adult-onset diabetes) is starting to occur in children as a result of obesity
pancreatic cancer peaks in 60s and most common on older men
acute pancreatitis is common in older adults (in younger ppl acute pancreatitis is associated with alcholism while odler adults get acute pancreatistis from gallstones blocking pancreatic duct)
How to diagnose and treat diarrhea/
