Knowledge Lesson Please follow along with your hand outs and take notes.
Skill Lesson
Powerpoint presentation with associated handouts.
Learning Support:
a. Structure and function(s) of the pancreas
(1) The pancreas lies behind the stomach in the concavity produced by the C-shape of the duodenum
(2) It is both an exocrine and endocrine gland
(a) Exocrine gland secretes pancreatic juice via the pancreatic duct to the common bile duct and to
the duodenum via the papilla of Vater
1) Pancreatic juice is the most important digestive juice. It contains enzymes (protease, lipase and
amylase) that digest all three major kinds of foods: fats, protein, and carbohydrates
2) It also contains sodium bicarbonate, an alkaline substance that neutralizes the hydrochloric acid
in the gastric juice that enters the intestines
(b) Endocrine gland that secretes hormones in the blood
1) Beta cells of Islets of Langerhans secrete insulin to decrease blood sugar
2) Alpha cells secrete glucagon to increase blood sugar

Skill Lesson
Powerpoint presentation with associated handouts.
Learning Support:
a. Etiology/pathophysiology
(1) Inflammation of the pancreas, ranging from mild edema and inflammation to enzymatic digestion
of the pancreas, extensive hemorrhage and necrosis
(2) The function of the pancreas usually returns to normal within 6 months after an acute attack
(3) Pancreas becomes inflamed when there is reflux of bile and duodenal contents into the pancreatic
duct, causing swelling and obstruction
a) Pancreas begins to digest itself (autodigestion) with its own enzymes (especially Trypsin)
(4) Swelling of the opening of the pancreatic duct impairs or obstructs the release of
a) Bicarbonate, which is released to neutralize the GI contents
b) Trypsin, which digests proteins
c) Amylase, which digests carbohydrates
d) Lipase, which digests fats
(5) Trapped enzymes begin to act on pancreas itself
(6) Causes
a) Structural/vascular abnormalities
b) Trauma or disruption of the pancreatic ducts
3
AFAMS Master Lesson Plan (MLP)
Nursing Program
Disorders of the Pancreas
c) Infectious disease
d) Metabolic disorders (hyperlipidemia, hypercalcemia)
e) Inflammatory bowel disease
f) Heredity
g) Excessive alcohol intake and certain drugs
h) Re-feeding after prolonged fasting or anorexia
i) Many people who have no other illnesses may develop acute pancreatitis
b. Clinical manifestations
(1) Necrosis (caused by auto-digestion)
(2) Hyperglycemia, hypocalcemia
(3) Hemorrhage of the gland with hypovolemic shock
(4) Peritonitis, pancreatic abscess, pseudocyst
(5) Severe fluid and electrolyte imbalance, acute renal failure
(6) Sepsis
(7) Pleural effusion, ARDS
(8) Blood coagulopathies
c. Assessment
(1) Most common - severe mid-upper abdominal pain, which may radiate to both sides and straight
through the back
(2) Nausea, vomiting and flatulence
(3) Stools may be frothy and foul smelling
(4) Jaundice may be noted if common bile duct is obstructed
(5) Bowel sounds may be diminished, with abdominal distention and tenderness
(6) Hypotension and hypovolemia from third spaced fluid and protein (due to systemic inflammatory
process)
(7) May also have Cullen's (bluish discoloration around the umbilicus) and Turner's (discoloration on
the flanks - both indications of pancreatic bleeding) signs
4
AFAMS Master Lesson Plan (MLP)
Nursing Program
Disorders of the Pancreas
(8) Fever, tachycardia
(9) Chvostek's and Trousseau's signs
d. Diagnosis
(1) Elevated serum and urine amylase, lipase and AST/ALT
(2) Bilirubin may be elevated with obstructed common bile duct
(3) CBC - elevated WBC
(4) Hyperglycemia, hypocalcemia, hypokalemia, hypomagnesemia
(5) CT scan (pancreatic edema and necrosis)
(6) Endoscopic and Ultrasound exams to determine pancreatic cysts, abscesses and pseudocysts
(fibrous capsules filled with fluid, blood, enzymes, pus and tissue debris)
e. Medical management
(1) Measures taken to relieve pain and spasms (cause an increase in pancreatic secretions)
(a) Demerol is usually the medication of choice
(b) Usually NPO, with NG tube to low continuous suction to relieve distention, N/V, and reduce
stimulation of pancreas to release juices
(c) Atropine, or anticholinergics, to reduce activity of vagus nerve (Vagus nerve controls stomach
activity)
(d) Cholecystectomy for gallstone pancreatitis
NOTE: Morphine may cause spasms of the Sphincter of Oddi and should be avoided
(2) Restore fluid and electrolyte losses
(a) IV fluids
(b) Albumin may be given IV to pull fluid trapped in peritoneum back into circulation
(3) Prevent or treat systemic complications, i.e., respiratory distress syndrome, bleeding abnormalities
(a) Antibiotics (IV) to prevent localized abscesses and/or systemic sepsis
(b) Percutaneous needle aspiration to treat pseudocysts
(c) Patient may require debridement of necrotic tissue every 2 to 3 days
5
AFAMS Master Lesson Plan (MLP)
Nursing Program
Disorders of the Pancreas
1) Multiple drains may be placed in the abdomen to drain fluid and debris
2) Continuous irrigation may be performed
(4) With improvement, clear liquid diet with progression to low-fat diet
(5) Alcohol, caffeine and pepper, which are digestive stimulants, are to be avoided
Knowledge Lesson:

Skill Lesson
Powerpoint presentation with associated handouts.
Learning Support:
a. Etiology/pathophysiology
(1) Prolonged, progressive inflammation of the pancreas
(2) With chronicity, the gland undergoes fibrotic scarring from recurrent inflammation
(3) The pancreas hardens and exocrine and endocrine functions are partly or completely lost as
pancreatic tissue is destroyed
(4) Causes
(a) Chronic alcohol abuse is the most common (leads to edema of the duodenum and decreases the
tone of the sphincter of Oddi with movement of duodenal contents into the pancreatic duct)
(b) Hyperparathyroidism
(c) Trauma to the pancreas
(d) Hereditary pancreatitis
(e) Hypertriglyceridemia
(f) Autoimmune pancreatitis
6
AFAMS Master Lesson Plan (MLP)
Nursing Program
Disorders of the Pancreas
(g) Repeatedly formed gallstones
(h) Most causes of chronic pancreatitis are similar to those of acute
(i) For some, the cause is unknown
NOTE: With chronicity, the gland undergoes fibrotic scarring due to the recurring inflammation. The
pancreas becomes hard, which then results in the partial to complete loss of gland function as pancreatic
tissue is gradually destroyed
(5) Complications
(a) Similar to those of acute pancreatitis
(b) Biliary tract obstruction
(c) Partial to complete loss of gland function
b. Assessment
(1) Persistent pain in epigastrium or LUQ radiating to the back
NOTE: Pain is sometimes relieved by assuming a forward position, taking the stomach weight off the
pancreas
(2) Weight loss
(3) Flatulence, vomiting and diarrhea
(4) Firm mass may be felt in upper left quadrant
(5) Dark urine
(6) Light colored and foul smelling stools, steatorrhea
(7) If pseudocysts are present, they contribute to severity of symptoms
(8) If secondary diabetes occurs, patient may have increased appetite, thirst and urination
(9) Peripheral edema and ascites (from loss of protein and fluid into third space)
c. Diagnosis
(1) Abnormal labs, as with acute pancreatitis
(2) CT, MRI and ultrasonography
(3) ERCP (Endoscopic Retrograde Cholangiopancreatography)

AFAMS Master Lesson Plan (MLP)
Nursing Program
Disorders of the Pancreas
(4) Glucose tolerance test - shows impaired ability to metabolize carbohydrates due to endocrine
dysfunction
d. Medical management
(1) Depends on cause and whether pancreatic duct is obstructed
(2) If no obstruction
(a) Abstinence from alcohol
(b) Clear liquid, advance to fat free diet
(c) Correction of biliary tract disease and/or hyperparathyroidism may give good results
(3) Demerol is ordered cautiously, but focus is on non-opioid pain management
(4) Insulin and pancreatic enzyme replacement
(a) Pancreatin (Creon, Bioglan, Panazyme, Donnazyme, Entozyme)
(b) Pancrelipase (Pancrease, Cotazyme, Creon 10 and Creon 20, Protilase, Ultrase, Viokase, Zymase,
Pancreacarb)
(5) Partial or total pancreatectomy
(6) Reconstitution of the duct with scarring, stricture and stenosis
(7) Pancreatojejunostomy
(8) Pancreatic autotransplantation
(a) Excision and relocation of the pancreas
(b) Innervation is cut, relieving pain symptoms
(c) Exocrine function is lost, but endocrine function is retained
(d) Will require lifelong supplements

Disorders of the Pancreas
a. Etiology/pathophysiology
(1) Fourth leading cause of cancer death in men and sixth in women
(2) High death rate attributable to the difficulty in diagnosing the cancer at a curable stage
(3) Occurs after middle age with a peak incidence around age 60
(4) Found in cigarette smokers, those exposed to chemical carcinogens and people with diabetes
mellitus
(5) Linked to diet high in meat, fat and coffee consumption
(6) May be primary or metastasis from lung, stomach, duodenum or common bile duct
(7) Tumor grows rapidly and quickly invades surrounding organs and tissue
(8) Many patients live only 4 to 8 months after diagnosis
b. Assessment
(1) Vague symptoms, which accounts for the delay in diagnosis
(2) Pain present in 85% of cases
(3) Anorexia, nausea, flatulence, change in stools
(4) Fatigue
(5) Steady, dull and aching pain in the epigastrium or referred to the back; usually worse at night
(6) Weight loss
(7) Jaundice, pruritis
(8) Recent onset of diabetes mellitus
c. Medical management
(1) Definitive diagnosis before surgery is difficult
(2) However, tumors are usually inoperable by the time the diagnosis is made
(3) Whipple procedure often performed (see Christensen p. 246)
(a) Pancreatoduodenectomy
(b) Resection of the antrum of the stomach, duodenum and varying sections of the pancreas
11
AFAMS Master Lesson Plan (MLP)
Nursing Program
Disorders of the Pancreas
(c) Anastomoses are constructed between the stomach, common bile duct and pancreatic ducts, and
the jejunum
(4) Total pancreatectomy with resection of parts of the GI tract
(5) Subtotal pancreatectomy has complications of postoperative pancreatic fistulas and is not
recommended
(6) Chemotherapy
(a) Combinations of drugs (5-FU and BCNU [carmustine]) produce a better response than single
agents
(b) Gemzar is a new chemotherapeutic agent for patients with metastatic adenocarcinoma that has
previously been treated with 5-FU
(7) Adjuvant therapy (surgical resection, radiation and chemotherapy) is believed by some to be the
most effective treatment of the almost always fatal pancreatic cancer
(8) Immediate post-operative care is usually done in the intensive care setting
