1. Fish shaped lobulated gland. Covered with five connective tissues

2. Weighs less than four ounces3. Three segments Head Body Tail4. Both cellular and ductal system5. Cellular System Endocrine Exocrine

Page 4: PANCREAS

6. Endocrine Alpha cells produce glucagon Beta cells produce insulin Delta cells produce somatostatin7. Exocrine - acinar cells Make up most of the pancreas Production and secretion of pancreatic juices is

1000cc – 2500cc/day Juice is colorless, alkaline, pH is 8.3 Components are: water, bicarb, enzymes, K+,

Cl, Ca++ Pancreatic juices neutralize acidic chyme

Page 5: PANCREAS

Exocrine- Acinar Cells THREE TYPES of Pancreatic Enzymes Amylase - breaks down carbs into sugar Lipase - early stages of fat digestion Protease - breaks down amino acid

bonds of protein chain8. Endocrine products are released directly

into the systemic circulation.9.Pancreatic Juices use the pancreatic ductal

system as mode of transport

Pancreatitis – Inflammation of the pancreas from obstruction of the pancreatic duct, trauma, toxicity from alcohol, infections, and drugs.

Signs and Symptoms - pain, nausea, vomiting, low grade fever, abdominal swelling, Low blood pressure, anorexia, weight loss, hypoxia, and increased serum amylase

Treatment Treat the symptoms - adequate pain relief,

NPO, NG Tube, bed rest, TPN, blood transfusion if needed, insulin if needed, and intensive care

Most patients improve after diagnosis within several days

Pseudo cyst - is an encapsulated sac that is lined by granulation tissue but no epithelium and is filled with pancreatic fluid and sometimes blood

Symptoms – epigastric pain, nausea, vomiting, weight loss, occasional jaundice and fever.

Treatment – Conservative treatment for pancreatitis. Usually form after pancreatitis

Drainage of cyst

Pancreatic cancer is the fourth most common cancer related death in the US.

Symptoms - RUQ pain radiates to the back, anorexia, and weight loss.

Treatment- depends on the staging of the cancer. Treatment of symptoms.

Zollinger-Ellison Syndrome (ZES) = gastrinoma or non beta islet cell tumor of the pancreas releases the hormone gastrin into the circulation which stimulates gastric acid hyper secretion and in turn leads to severe ulcers in the upper GI tract.

Symptoms - pain as with peptic ulcer disease, diarrhea , steatorrhea, elevated serum gastrin

Treatment - long term PPI

Cystic Fibrosis - autosomal recessive disease of the exocrine glands that not only affects the pancreas but also the respiratory system, the sweat glands and the reproductive system

CF- A hereditary disorder of infants, children, and young adults in which there is widespread dysfunction of the exocrine glands. It is characterized by signs of pulmonary disease caused by excessive mucus production in the respiratory tract, pancreatic deficiency, and abnormally high levels of electrolytes in the sweat and occasionally by biliary cirrhosis .

Page 11: PANCREAS

Diagnostic test is sweat electrolyte test – elevated sodium and chloride.

Treatment includes managing respiratory complications, aiding digestion through dietary regulation, pancreatic enzyme replacement and replacement of Vitamins A, D, E and K

A developmental anomaly in which the pancreas is present as two separate structures each with its own duct.

Causes pancreatitis. Diagnosis by pancreatography ERCP

Treatment - Sphincterotomy

The second most common cause of pancreatic insufficiency.

Main features presented are pancreatic insufficiency, cyclic neutropenia, metaphyseal and growth retardation. Dental abnormalities, renal dysfunction, hepatomegaly, abnormal lung function, delayed puberty, and ichthyosis, malabsorption infancy with steatorrhea. The most prevalent feature is stunted growth.

Diagnosed with a pancreozymin/secretin stimulation test – low or absent pancreatic zymogen enzymes.

High stool fat content. Stools are greasy ,pale, and foul smelling.

The three leading causes of pancreatitis in children are trauma, drugs and viral infection.
