Gi Gallbladder & Pancreas

  1. 1. Pascale Gehy-Andre PA-C Diseases of Gallbladder & Bile Ducts
  2. 2. Anatomy of the Gallbladder <ul><li>A. A pickle shaped sac that is 8-10 cm long c a capacity of about 50 ml. </li></ul><ul><li>B. Divided into: </li></ul><ul><ul><li>Neck: (has a small pouch called Hartmann’s pouch. This is the location of most of the pathology) </li></ul></ul><ul><ul><li>Body </li></ul></ul><ul><ul><li>Fundus </li></ul></ul><ul><li>C. Contracts after a fatty meal is ingested. </li></ul>Add a picture here.
  3. 3. Biliary Anatomy <ul><li>Hepatocytes  canaliculi  biliary ductules  </li></ul><ul><li>L & R hepatic ducts  common hepatic duct </li></ul><ul><li>Common hepatic ducts & Cystic Duct  Common Bile Duct (CBD) </li></ul>
  4. 4. Bile Production <ul><li>A. Bile is an isotonic mixture consisting of </li></ul><ul><ul><li>1. electrolytes </li></ul></ul><ul><ul><li>2. Protein </li></ul></ul><ul><ul><li>3. bile salts </li></ul></ul><ul><ul><li>4. cholesterol </li></ul></ul><ul><ul><li>5. phospholipids- (phospholipids: contain phos. & on hydrolysis yield fatty acids, glycerol, lethicin, & cephalins. Phospholipase is the enzyme found in liver & pancrease) </li></ul></ul><ul><ul><li>6. bile pigment </li></ul></ul>
  5. 5. Bile Production <ul><li>B. Cholate & chenodeoycholate which are bile salts are synthesized by hepatocytes from cholesterol in a multi-step procedure. </li></ul><ul><li>C. Cholecystokinin (pancreatic enzyme) is released from the small bowel after a fatty meal, stimulates the GB to contract & sphincter of oddi to relax </li></ul><ul><li>D. Bile acids aid in the absorption of fat forming micelles which are absorbed in the small bowel. </li></ul><ul><li>E. The bile salts are reabsorbed in the small bowel & transported back to the liver. Averaging 9x’s/day. </li></ul>
  6. 6. Bile Acid Insufficiency <ul><li>1. Insufficient bile acids can result from a disorder at any step in enteropathic circulation </li></ul><ul><ul><li>A. liver disease with decreased production of acids </li></ul></ul><ul><ul><li>B. obstruction of the duct </li></ul></ul><ul><ul><li>C. Bacterial overgrowth </li></ul></ul><ul><ul><ul><li>(bile acids are conjugated before they can participate in fat absorption) </li></ul></ul></ul><ul><ul><li>D. Disorders of the terminal ileum which decrease the absorption of the bile salts. </li></ul></ul>
  7. 7. Bile Acid Insufficiency (cont) <ul><li>2. Bile acids facilitate the absorption of dietary fat by the formation of intraluminal micelles. </li></ul><ul><li>Therefore if absent will result in malabsorption of fat. </li></ul><ul><li>Treatment </li></ul><ul><ul><li>A. Tetracycline for small bowel overgrowth </li></ul></ul><ul><ul><li>B. Terminal ileum disorders should be treated </li></ul></ul><ul><ul><li>C. Use of medium chain triglycerides are helpful </li></ul></ul><ul><ul><li>Note: failure to correct allows bile acids to enter the large bowel producing diarrhea. </li></ul></ul>
  8. 8. Cholelithiasis (Gallstones) <ul><li>Definition: presence of concretions in the gallbladder or bile ducts. </li></ul><ul><li>1. Affects 20 million people/year </li></ul><ul><li>2. Stone type </li></ul><ul><ul><li>A. Cholesterol (70%) (most common) </li></ul></ul><ul><ul><ul><li>All ages </li></ul></ul></ul><ul><ul><ul><li>Mostly women </li></ul></ul></ul><ul><ul><ul><li>Use of estrogen </li></ul></ul></ul><ul><ul><ul><li>Obesity </li></ul></ul></ul><ul><ul><ul><li>Diabetes </li></ul></ul></ul><ul><ul><ul><li>Disease of small bowel & sphincter </li></ul></ul></ul>
  9. 9. GallStones (Cholelithiasis) <ul><li>2. Stone type (cont): </li></ul><ul><ul><li>B. pigment 30% </li></ul></ul><ul><ul><ul><li>(calcium bilirubinate) </li></ul></ul></ul><ul><ul><ul><li>Mostly bilirubin </li></ul></ul></ul><ul><ul><ul><li>Hemolytic states, cirrhosis & elderly </li></ul></ul></ul><ul><li>3. Mixed </li></ul>
  10. 10. Interrelation of gallbladder disease <ul><li>1. Cholecystitis is associated with cholelithiasis in 85%-90% of cases </li></ul><ul><li>2. Regurgitation of pancreatic acid causes non-bacterial cholecystitis </li></ul><ul><li>3. Bile stasis due to sphincter of oddi spasm or obstruction is a cause of inflammation </li></ul><ul><li>4. Gangrene of GB is due to chronic cholecystitis </li></ul><ul><li>5. A porcelain GB (heavily calcified) should be removed surgically because of increased risk of GB cancer </li></ul>
  11. 11. Diagnostic Studies <ul><li>A. Chemistry, CBC, LFT’s, amylase </li></ul><ul><ul><li>1. CBC elevated in cholecystitis c slight elevation of LFT’s </li></ul></ul><ul><ul><li>2. Biliary obstruction: bilirubin, alk phos & amylase may be elvated. </li></ul></ul><ul><li>B. Plain film of the abdomen is of poor value. </li></ul><ul><li>Only 15-20% of stones are radiopaque. </li></ul><ul><li>C. Oral Cholecystogram: </li></ul><ul><ul><li>Requires patient to take pills </li></ul></ul>
  12. 12. Diagnostic Studies (cont) <ul><li>D. Ultrasound: </li></ul><ul><ul><li>Most sensitive and specific test for the detection of gallstones </li></ul></ul><ul><ul><li>Limited in obese patients </li></ul></ul><ul><ul><li>Simple to do & safe </li></ul></ul><ul><ul><li>No preparation needed </li></ul></ul><ul><ul><li>May show thinkened wall in acute cholecystitis </li></ul></ul><ul><li>E.

CT scan </li></ul>
  13. 13. Treatment of Cholelithiasis (Gallstones) <ul><li>1. Pain relief </li></ul><ul><li>2.

  29. 30. Pancreas <ul><li>Anatomy </li></ul><ul><ul><li>Head: embraces the duodenal curve </li></ul></ul><ul><ul><li>Body: crosses the vertebral column </li></ul></ul><ul><ul><li>Tail: in the hilum of the spleen </li></ul></ul>
  30. 34. Pancreas Physiology <ul><li>1. Islets of Langerhans: responsible for the production of: </li></ul><ul><ul><li>A. Insulin </li></ul></ul><ul><ul><li>B. Glucagon: </li></ul></ul><ul><ul><ul><li>A hormone that is produced by the alpha cells of langerhan that produces glucose from glycogen. </li></ul></ul></ul><ul><ul><li>C. Gastrin </li></ul></ul><ul><ul><li>D. Somatostatin </li></ul></ul><ul><ul><ul><li>Gastrin and somatostatin are mostly in stomach, but also in pancreas, stimulates HCL stopping agents. </li></ul></ul></ul>
  31. 35. Pancreas Physiology (cont) <ul><li>2. Enzymes secreted from ducts: </li></ul><ul><ul><li>Amylase (CHO) </li></ul></ul><ul><ul><li>Lipase (Fats) </li></ul></ul><ul><ul><li>Trypsinogen (Protein) </li></ul></ul><ul><ul><ul><li>Is converted to trypsin in the duodenum so as not to cause autodigestion </li></ul></ul></ul><ul><ul><ul><li>NOTE: Liver produces alpha trypsin to protect against autodigestion </li></ul></ul></ul>
  32. 36. Pancreas Physiology (cont) <ul><li>3. Pancreatic secretion stimulated by two hormones: </li></ul><ul><ul><li>Secretin : </li></ul></ul><ul><ul><ul><li>Produced in the duodenum & stimulated by acid </li></ul></ul></ul><ul><ul><ul><li>Inhibits gastric acid </li></ul></ul></ul><ul><ul><ul><li>Stimulates pancreas to produce bicarb & chloride </li></ul></ul></ul><ul><ul><li>Cholecystokinin : </li></ul></ul><ul><ul><ul><li>A pancreozymin which is released in response to fat & amino acids in the duodenum </li></ul></ul></ul><ul><ul><ul><li>Stimulates pancreas to produce amylase, lipase, & trypsin </li></ul></ul></ul>
  33. 37. Pancreas Physiology (cont) <ul><li>4. The pancreas secrets 1-4 Liters of fluid per day </li></ul><ul><li>5. The pancreatic juice is usually alkaline. </li></ul><ul><ul><li>Food in duodenum causes secretion of secretin (due to high acid content). Secretin releases H2O & bicarb. </li></ul></ul><ul><li>6. In pancreatitis we use foods low in fat & protein because they stimulate secretion from the pancreas. CHO is a weaker stimulant. </li></ul><ul><li>7. Pancreatic enzymes inhibit gastric secretion of its enzymes. </li></ul>
  34. 38. Acute Pancreatitis <ul><li>Etiology: Alcohol & Gallstones = 80-90% </li></ul><ul><ul><li>Other causes: </li></ul></ul><ul><ul><ul><li>Complications of ERCP (endoscopic retrograde cholangiopancreatography) </li></ul></ul></ul><ul><ul><ul><li>Trauma </li></ul></ul></ul><ul><ul><ul><li>Infections (mumps/ viral) </li></ul></ul></ul><ul><ul><ul><li>Hyperlipidemia: TG > 1000 mg </li></ul></ul></ul><ul><ul><ul><li>Hypercalemia </li></ul></ul></ul><ul><ul><ul><li>Drugs (thiazides, lasix) </li></ul></ul></ul><ul><ul><ul><li>Idiopathic </li></ul></ul></ul>
