Term
the ? is a gland in the abdomen lying in the curvature of the stomach as it empties into the duodenum; the pancreas functions primarily as an ? gland although it also has ? function; the exocrine cells of the pancreas are called ? cells that produce ? fluid known as pancreatic juic that contains various digestive enzymes; the pancreatic juice is released through the ampulla of Vater into the ? to aid in the digestive process as well as buffer acidic fluid released from the stomach
Definition
pancreas; exorine; endocrine; acinar; alkaline; duodenum
Term
the digestive enzymes are produced and stored as inactive ? with ? granules to prevent autolysis and digestion of the pancreas; the zymogen granules are also responsible for enzyme transport to the ? duct; ? and ? are released from the zymogen granules in their active form, whereas the ? enzymes are activated in the duodenum by ?; enterokinase triggers conversion of ? to the active protease ?; trypsin then activates the other proenzymes to their active enzymes; the pancrease contains a ? inhibitor to prevent autolysis
Definition
proenzymes; zymogen; pancreatic; amylase and lipase; proteolytic; enterokinase; typsinogen; trypsin; typsin
Term
in the western hemisphere, acute pancreatitis is caused mainly by ? use/abuse and ? (cholelithiasis); other common causes of acute pancreatits include ?, endoscopic retrograde cholangiopancreatography, ?, and autodigestion due to early activation of pancreatic enzymes as well as numerous ?
Definition
ethanol; gallstones; hypertriglyceridemia; pregnancy; medications
Term
ethanol abuse may cause precipitation of ? enzymes in the ducts of the pancreas, leading to chronic ? and ? reulting in loss of exocrine function; ? may obstruct the ampulla of Vater causing pancreatic enzymes or bile to move in a ? fashion into the pancreas and this may be responsible for pancreatic ?; autolysis in the pancreas can occur when ? are activated in the pancreas before being relased into the duodenum; acute pancreatits can result from the initial injury to the ? producing cells which is followed by ? invasion of the pancreas and further activation of enzymes within the pancreas; this cascade of events is harmful and destructive to patient
Definition
pancreatic; inflammation; fibrosis; gallstones; retrograde; autolysis; zymogen; zymogen; neutrophil
Term
a ? fluid collection (or pancreatic pseudocyst) is a collection of tissue, pancreatic enzymes, and blood that froms weeks after acute pancreatits; many of these resolve spontaneously, but some require ? drainage; rupture of these associated with erosion and hemorrhage of major abdominal blood vessels can have a mortality approaching 60%; pancreatic ? is a diffuse inflammation of the pancreas; pancreatic necrosis occurs within the first ? weeks of acute pancreatits and develops in 10-30% of patients with acute pancreatits; the necrotic pancreas can become secondarily infected with enteric gram ? bacteria such as ?
Definition
pancreatic; surgical; necrosis; 2; negative; E. coli
Term
pancreatic ? is a collection of pus that forms in the pancreas 4 to 6 weeks after acute pancreatitis; pancreatic abscess is usually ? life threatening than pancreatic necrosis or pancreatic pseudocyst and can be managed with percutatneous ?; pancreatic ? can occur when pancreatic abscesses become secondarily infected and this infection is usually due to bacteria that are ? found in the GI tract
Definition
abscess; less; drainage; necrosis; normally
Term
a patient with acute pancreatits may develop many severe ? and ? complications; ? pain and distention may be due to local complications such as fluid collection, necrosis, or abcess in the pancreas; ?, ? and ? may result from systemic complications, which can affect virtualy any organ system but tend to target the ? and ? systems and the ?; ? ? (ARDS) is a life threating syndrome of acute lung injury with resulting hypoxia; patients at greatest risk for mortality from acute pancreatits are those who have multiorgan failure such as ?, ? failure, or ? failure or those with pancreatic ?, obesity, volume depletion, above ? years of age and elevated APACHE II score
Definition
local; systemic; abdominal; hypotension, tachycardia, fever; pulmonary, cardiovascular, kidney; Acute Respiratory Distress Syndrome; hypotension; renal; respiratory; necrosis; 70
Term
diagnosis of acute pancreatits is based on the patient's ? and presenting ? and ?; evaluation of laboratory results, specifically the serum ?, aids in diagnosis; serum ? is elevated early in the disease process but may return to normal within ? hours; although an elevated serum amylase had been the diagnostic standard, its utility is now limited by lack of specificity; serum ? and ? are now the gold standards for laboratory testing; serum lipase will remain elevated for ? after the acute event; ? is more complicated than abdominal radiography or ultrasound, but it is the most useful tool for diagnosis and staging of acute pancreatitis
Definition
history; signs and symptoms; lipase; amylase; 12 hours; lipase; colipase; days; CT scan
Term
the goals of treatment for acute pancreatitis include: resolution of ?, ?, ? pain, and ?; ability to tolerate ? intake; normalization of serum ?, ?, ? count; resoultion of abcess, pseudocyst, or fluid collection as measured by ? scan
Definition
nausea, vomiting, abdominal, fever; oral; lipase, amylase, white blood cell; CT scan
Term
if a medication is determined to be the cause of acute pancreatitis, it should be ? and an ? therapy should be considered; therapy of acute pancreatitis is primarily ? unless a specific etiology is identified; supportive therapy involves ? repletion, ? support, and ?
Definition
discontinued; alternative; supportive; fluid; nutrition; analgesia
Term
patients with acute pancreatitis are administered ? fluids to maintain hydration and blood pressure in the form of ? or ?; ? at a rate of 50 to 100 ml/h is reasonable for patients with mild to moderate fluid depletion; however, as much as 200 ml/h may be required for patients with severe fluid losses; electrolytes such as ? and ? may be added to the infusions if necessary; hyperglycemia can be managed with ?
Definition
IV; crystalloids; colloids; normal; potassium; magnesium; IV insulin
Term
it is common practice to discontinue oral ? during an attack of acute pancreatitis; in theory, discontinuation of oral intake will decrease ? functions of the pancreas and minimize further complications from the disease; ? feeding delivered via a ? tube will feed the patient beyound the ampulla of Vater, minimizing the stimulation of the pancrease; if oral intake is discontinued for a protracted period, ? nutrition must be used to maintain adequate nutrition
Definition
feedings; secretory; tube; nasojejunal; parenteral
Term
if pancreatic necrosis has been identified, ? debridement is necessary because mortality approaches ?% without drainage or surgical intervention; ? has historically been the most popular analgesic in acute pancreatitis because it is purported to cause less ? and resulting in pain in the sphincter of ? than other analgesics however the clinical importance of this phenomenon is unclear and as a result patients should be given the most effective analgesic; ? and ? are reasonable alternatives to meperidine and may be more desirable due to other adverse effects associated with meperidine
Definition
surgical; 100%; meperidine; spasm; Oddi; hydromorphone; fentanyl
Term
empiric ? are not necessary if the patient has mild disease or a noninfectious etiology of acute pancreatitis; antibiotics have not been shown to prevent the formaation of pancreatic abscess or necrosis when given early in the course of acute pancreatitis
Definition
antibiotics
Term
antibiotics may be appropriate for pancreatic ?, which can be infected initially or be susceptible to a secondary infection; however, published data yield conflicting results regarding mortality and infection rate in this setting and as such the decision to use antibiotics is highly individualized; if necrosis is confirmed, antibiotics are insufficient as sole therapy and ? debridement is necessary for cure
Definition
necrosis; surgical
Term
? antibiotics with activity against enteric gram ? bacilli are appropriate; patients may receive ? courses of broad spectrum antibiotics such as ? and may develop superinfections due to more resistant bacteria or bacteria not susceptible to meropenem; antifungal drugs such as ? may be considered if peritonitis or GI perofration develops due to the presence of such fungi as ? in the GI tract
Definition
broad spectrum; negative; long; meropenem; fluconazole; candida albicans
Term
several pharmacologic therapies have been proven to be ineffective in reducing morbidity and mortality from the disease such as reducing pancreatic secretions by reducing ? or ?, reducing gastric acidity and decreasing pancreatic secretion with ?, inhibition of pancreatic enzymes usine ? inhibitors such as aprotinin, probiotics, and immunomodulation
Definition
somatostatin; atropine; H2 antagonists; protease
Term
the incidence of chronic pancreatitis is approximately one in ? people; the most common cause of chronic pancreatits in adults in Western countries is ? abuse; the most common cause in children is ? due to pre existing pancreatic insufficiency inherent in the disease; ? can occur at the same time as chronic pancreatitis but are not often implicated as the cause; unlike acute pancreatits, chronic pancreatits has an ? etiology in a significant number of cases
Definition
10,000; ethanol; cystic fibrosis; gallstones; unknown
Term
the amount of ethanol consumed does not correlate with the incidence or progression of ? pancreatitis; the inflammation damages the ? producing cells in the pancrease and can also disrupt or destroy the ? function of the pancrease by causing diffuse scarring and fibrosis; long term sequalae of chronic pancreatits include dietary ?, impaired ? tolerance, cholangitis, and potential addiction to ? analgesics
Definition
chronic; enzyme; endocrine; malabsorption; glucose; opioid
Term
as patients lose ? function of the pancreas, they have decreased ability to absorb ? and ? ingested with normal dietary intake; ? loss from nutritional malabsorption is a common symptom of chronic pancreatitis not often seen in acute pancreatitis; ? or ? containing stools are also common; ? absorption is usually unaffected; no incidence of fat soluble ? deficieny in patients with chornic pancreatitis
Definition
exocrine; lipids; proteins; weight; fat; protein; carbohydrate; vitamin
Term
differentiating an episode of acute from chronic pancreatitis may be difficult because clinical presentations can be similar; the diagnosis of chornic pancreatitis is made by looking for the effects of chronic pancreatic inflammation and ? on the pancreas and the patient as a whole; ? or ECRP will allow visualization of chronic calcified lesions in the pancreas when present
Definition
scarring; CT
Term
the goals of pharmacotherapy for chronic pancreatits are prevention and resolution of chronic ? pain and correction of dietary malabsorption with exogenous ? enzymes; ? modifications are an important part of the therapy for chornic pancreatitis; patients should be advised to completely avoid ? and ? meals which will help decrease the pain; most ? procedures in the treatment of chronic pancreatitis have not been proven to be effective (including nerve blocks)
Definition
abdominal; pancreatic; lifestyle; ethanol; fatty; surgical
Term
? management is an important component of therapy and is similar to that of acute pancreatitis; nonopioid analgesics such as ? are preferred, but the severe and persistent nature of the pain often requires ? therapy; patients can require chronic doses of opioid therapy with a resulting risk of ?
Definition
pain; tramadol; opioid; addiction
Term
the goal of pancreatic ? supplementation is to deliver exogenous enzymes to the ? without causing further GI side effects from the medication; supplementation with pancreatic enzymes may reduce the ? and ? diarrhea associated with chronic pancreatitis; common pancreatic enzyme produces contain ?, ? and ? in varying proportions thus the dose can be tailored to the patient
Definition
enzyme; duodenum; pain; fatty; lipase, amylase, protease
Term
? coated pancreatic enzyme supplements require ? doses to compensate for loss of enzyme due to destruction by the low pH stomach; this effect can be minimized by administering ? or ?; these non enteric coated pancreatic enzyme supplements may have an advantage in minimizing ? early in the disease state through regulation of proteases in the duodenum; these can be used for initial therapy and the relative dose of amylase, lipase, and protease may be increased until control of ? and ? diarrhea are achieved; if pain and diarrhea control are achieved, the patient may be transitioned to an ? coated supplement to maximize compliance
Definition
nonenteric; high; H2 antagonists; PPIs; pain; pain; fatty; enteric
Term
most pancreatic enzyme supplements are ? coated to release enzymes in the alkaline environment of the intestine; this minimizes ? destruction in the stomach; enteric coated pancreatic enzyme supplements require ? daily dosage units, but delivery of the drug to the site of action and effectiveness may be delayed by gastric emptying time; pancreatic enzymes should be taken immediately prior to ? to aid in the digestion and absorption of food; alternately, patients can supplement their diet with medium chain ? (MCTs) since they do not require pancreatic enzymes for absorption; once the patient is switched from the nonenteric coated to the enteric coated the H2 receptor antagonist or PPI can be ?
Definition
enteric; enzymatic; lower; meals; triglycerides; discontinued
