A

Inflammation of the gallbladder
Usually caused by stones that irritate the gallbladder, causes obstruction of cystic duct
Over 90% of cases due to calculous

116
Q

cholelithiasis

A

Calculi in gallbladder
Gallstones block cystic duct
Leads to cholecystitis

117
Q

choledocholithiasis

A

Stones in the common bile duct
Cholesterol stones or pigmented

118
Q

bile

A

stored in gallbladder
made and secreted in liver
food enters duodenum and digests food by bile
emulsifies fats
excretes RBCs
gives stool dark color

119
Q

gallbladder

A

Storage depot for bile
Release bile
CBD (common bile duct) connects gallbladder and duodenum

120
Q

incidence of cholecystitis

A

Obesity
Native americans
Increases with age (40+)
Women nearly 70% of cases
Hormone therapies (BC)
Mortality rate higher among men
Frequent changes in weight (rapid loss)
Diseases (diabetes, crohn’s, cystic fibrosis, ileal resection increases risk for cholelithiasis → cholecystitis)
Frequent surgeries
Anything that causes us to lose fluid causes crystallization leading to stones
Way to remember: fair, female, fat, over fourty

121
Q

cholecystitis causes what

A

high fat triggers attacks
calculus big cause
calculi make gallbladder inflamed, pain in RUQ, and edema. infection causes pus to leak in blood causing peritonitis
edema may cut off blood supply

122
Q

cholecystitis in elderly

A

may not show S&S until oliguria and septic shock

123
Q

acalculous

A

no gallstones

major surgery
trauma
severe burns
cysts
primary infection
blood transfusions
causes in fluid and electrolyte balance (dehydration)

124
Q

biliary colic

A

Spasm of biliary duct as it tries to push stone out
Severe pain RUQ
Radiate around to back and right shoulder
Triggered by large, rich meals

125
Q

clinical manifestations of cholecystitis

A

biliary colic (hallmark)
Rebound tenderness and rigidity at RUQ
N/V
Feeling of fullness
Fever
Exacerbations
Jaundice with CBD (common bile duct) obstruction; must be cholelithiasis
Pruritus (itching)
Clay colored stools
Steatorrhea (from lack of emulsification of stools, when there is obstructive jaundice)
Tea colored urine

126
Q

cholelithiasis

A

may go unnoticed until biliary colic with obstruction of cystic duct
As gallbladder becomes distended, pain intensifies
Blood tests show increase in bilirubin
Stone may retreat or pass

127
Q

pigment gallstone

A

from backup of bile

128
Q

cholesterol gallstone

A

Bile supersaturated with cholesterol bc of:
Decrease in bile acids dissolving cholesterol
OR
Increase in cholesterol

129
Q

diagnostics of cholelithiasis

A

Ultrasonography (NPO after midnight)
Cholecystography
ERCP (Diagnostic and treatment)
PCT (Treatment and diagnosis, looks at structures of the gallbladder and liver)
MRI (shows calcified stones)
Blood test (Non specific, to rule out other conditions, high WBC shows inflammatory process, + cholesterol can cause cholesterol stones, liver enzymes, pancreatic enzymes)
Abdominal x-ray (calcified stones)

130
Q

treatment of cholelithiasis

A

ERCP, PTC
Removing stones
Non surgical, endoscope in duodenum, wire snare placed in gallbladder, removes stone (complication is bleeding)
Extracorporeal lithotripsy (crushing of the stone)
Dissolve stones
Lies in cushion filled with water and high energy
sound waves, shatters the stone
Only if the stones are <4 in amount or <3 cm in
diameter
Drink 2-3 quarts of water a day to get rid of any
stone fragments
NG tube
low fat
avoid alcohol
avoid gas forming foods
avoid fried foods
eat high carbs and protein

131
Q

surgeries for cholelithiasis (once symptoms subside)

A

Laparoscopic cholecystectomy (fewer risks)
Camera used
Fine after 3-4 days
May complain of shoulder pain bc of injected air into
abdomen (tell pt that they can use heat applications
for 15-20 min every hour and ambulate to promote
CO2 absorption)
Bile duct injury serious side effect
Report abdominal symptoms
Open cholecystectomy
Can be delayed for 6 weeks until symptoms subside
Actual incision

132
Q

drug therapy for cholelithiasis

A

abx
lipid lowering agents
antispasmodics
analgesics (demerol NOT morphine unless severe)

133
Q

post op care for cholelithiasis

A

Assess
Monitor VS
Skin care around biliary drainage (some bile may leak out)
T-tube (300-400mL in first 24h, serosanguineous in the beginning, bile color after 24 hours, tube clamped during meals and 1-2 hours after meals, kept below gallbladder to prevent reflux and infection, emptied every 8 hours, pts may have diarrhea after cholecystectomy, but stool should be brown after a week, physician removes tube)
NG tube to relieve distension and vomiting
Pain control
I&O
Encourage activity
low fat diet, limit weight and pregnancies
cough and deep breathe

134
Q

what to report after cholelithiasis surgery

A

Fever (leads to cholecystitis)
Jaundice
Pruritus (itching can mean blockage with backup of bilirubin)
Dark color urine
Pale color stools
Rigidity of abdomen (peritonitis)
Sudden drop in BP (shock)
Gangrene of gallbladder and peritonitis r/t perforation
Resp problems (frequent problem, hard to deep breathe bc of place of incision)

135
Q

dumping syndrome

A

Food rapidly enters jejunum without the benefit of normal digestive process
If a pt is getting tube feedings, they might get dumping syndrome
Can occur in anyone who had a surgery removing part of the stomach
Rapid gastric emptying or sudden influx of hypertonic fluid triggers a shift of fluid into the abdomen as the small intestines pull fluid from the EC space to try to dilute hypertonic fluid
Decrease in circulating volume causes vasomotor disturbances
Occurs within 10-30 mins after eating

136
Q

S&S of dumping syndrome

A

Vertigo
Tachycardia
Syncope
Sweating
Pallor
Palpitation
Diarrhea
Nausea
Weakness, they want to lie down
Happens after surgery and during tube feedings (dilute)
Symptoms resolve within an hour or from bowel movement
Hypoglycemia

137
Q

intestinal manifestation of dumping syndrome

A

Can occur 2-3 hours after a meal
Epigastric fullness
Distention of jejunum with food and fluid
Abdominal discomfort
Cramping
Nausea
Borborygmi (stomach rumbling)

138
Q

teaching for dumping syndrome

A

Small feeding
High protein and fat
Low CHO, fiber
Dry diet
Provide antispasmodic

139
Q

interventions for dumping syndrome

A

dry diet
low carb (stays in stomach longer)
lying down after eating to slow passage
high fat and protein
low fiber
small, frequent meals

140
Q

post-op for dumping syndrome

A

increased risk of hemorrhage
Bile reflux from removal of pylorus
Dysphagia
Bowel obstruction from adhesions

141
Q

GERD

A

Backflow of gastric content into esophagus as it goes past a weak or lower LES without belching or vomiting
results in esophagitis

142
Q

3 aggressive factors

A

HCl
bile
pancreatic enzymes

143
Q

2 protective factors

A

saliva
mucus

144
Q

GERD risk factors

A

Weight gain
Obesity
Pregnancy
Lying flat after meals
Medications (Ca+ channel blockers, BB, high levels of estrogen and progesterone, NSAIDS, stress cause reflux)
Hiatal hernia
Smoking
Weakened LES tone
Foods: tomatoes, citrus, spicy
Alcohol
Caffeine
Chocolate
Chewing tobacco
High fat foods
Carbonation
Elderly

145
Q

patho of GERD

A

Change in the pressure zone of gastroesophageal sphincter
Normally, high pressure prevents reflux but permits passage of food
Displacement of angle of gastroesophageal junction
Incompetent LES
Inflamed esophageal mucosa
Esophagitis from backflow of aggressive factors which puts pts at high risk for esophageal cancer

146
Q

Degree of GERD depends on

A

Frequency of reflux
Contents of reflux
Buffering ability of saliva and mucus
Rate of gastric emptying

147
Q

GERD clinical manifestations

A

dyspepsia (moves up and down, relieved with antacid)
pain (occurs after activity, supine or distended abdomen makes it worse, radiates to back of neck or jaw and penetrates to back, take nitroglycerin, worse when bending over or recumbent, don’t do strenuous exercise after eating, sit after meals, walk)
esophageal spasm
odynophagia (pain during swallowing)
intermittent dysphagia (worse in beginning of meal)
acid regurgitation (SOUR AND BITTER)
water brash (hypersalivation SALTY)
eructation (belching)
distended abdomen

148
Q

GERD diagnosis

A

barium swallow
esophagoscopy
Esophageal biopsy
Cytology (looking at cells)

Oversedation
Hemorrhage from perforation

150
Q

post op for esophagoscopy

A

Assess airway if pt not arousable
Check VS
Check for breathing
Check gag reflex!
Eating before it returns causes choking

151
Q

med management of mild GERD

A

Antacids (Al or Mg hydroxide), calcium carbonate
Maalox, mylanta (brand names)
Increase gastric pH
Reduce pepsin activity
Buffers/neutralize gastric acid to soothe mucosa
Works in 30 min
Should be taken AFTER a meal, not before
Neutralizing acid that forms after meals
Mg can cause diarrhea
