Most common disorder of biliary system
Risk factors
Female Multiparity Age older than 40 years Estrogen therapy Sedentary lifestyle Genetics/ethnicity Obesity
Etiology and patho
Cause of gallstones is unknown
Develops when balance that keeps cholesterol, bile salts, and calcium in solution is altered
Stasis of bile - sludge
Decreased bile flow
Clinical manifestations
Vary from severe to none at all
Pain more severe when stones moving or obstructing
-Steady, excruciating
-Tachycardia, diaphoresis, prostration
-May be referred to shoulder/scapula
-Residual tenderness in RUQ
-Occurs 3-6 hrs after high-fat meal or when patient lies down
Total obstruction symptoms
Jaundice Dark amber urine Clay-colored stools Pruritus Intolerance of fatty foods Bleeding tendencies Steatorrhea
Diagnostic Studies
Ultrasonography
ERCP
PTC
Blood work - Lab findings
Increased:
- WBC Count
- Serum bilirubin level
- Liver enzyme levels
- Serum amylase level
Collaborative Care
Oral dissolution therapy (ursodeoxycholic acid, chenodeoycholic acid)
ERCP w/ sphincterotomy
Transhepatic biliary catheter: to train purulent material
Extracorproeal shock-wave lithotripsy (ESWL)
Cholecystectomy (laparoscopic)
Treatment of choice Removal of gallbladder through one to four puncture holes Minimal postoperative pain Resume normal activities, including work within 1 week Few complications AFTER: -Liquids first day -Light meals for several days
Open (incisional) cholecystectomy
Removal of gallbladder through right subcostal incision
T-tube inserted into common bile duct
-ensures patency of duct
-allows excess bile to drain
AFTER:
-Liquids to regular diet after return of bowel sounds
-May need to restrict fats for 4-6 weeks
Nutritional Therapy
Small, frequent meals w/ some fat Diet low in saturated fat High in fiber and calcium Reduced-calorie diet if patient is obese Avoidance of rapid weight loss
Overall goals
Relief of pain and discomfort
No complications postoperatively
No recurrent attacks of cholecystitis or cholelithiasis
Health Promotion
Screen for predisopsing factors
Teaching for at-risk ethnic groups
Early detection of chronic cholecystitis
-Manage w/ low-fat diet
Nursing Goals
Relieve pain Relieve nausea and vomiting Provide comfort and emotional support Maintain fluid and electrolyte balance/nutrition Accurate assessments Monitor for complications
Acute interventions
Pain management Comfort measures Manage N/V Pruritus relief measures Monitor for complications -Obstruction -Bleeding -Infection
