Learning Objectives (Cont’d.):

CHOLECYSTITIS
• Acute inflammation of the gallbladder causes pain,
tenderness, and rigidity of the upper right abdomen that
may radiate to the midsternal area or right shoulder and
is associated with nausea, vomiting, and the usual signs
of an acute inflammation.
• An empyema of the gallbladder develops if the
gallbladder becomes filled with purulent fluid.
• Calculous cholecystitis is the cause of more than 90% of
cases of acute cholecystitis. In calculous cholecystitis, a
gallbladder stone obstructs bile outflow.
Disorders of the Gallbladder

DEFINITION OF TERMS
• Cholecystitis: inflammation of the gallbladder
• Cholelithiasis: the presence of calculi in the gallbladder
• Cholecystectomy: removal of the gallbladder
• Cholecystostomy: opening and drainage of the
gallbladder
• Choledochotomy: opening into the common duct
• Choledocholithiasis: stones in the common duct
• Choledocholithotomy: incision of common bile duct for
removal of stones
• Choledochoduodenostomy: anastomosis of common
duct to duodenum

DEFINITION OF TERMS
• Choledochojejunostomy: anastomosis of common
duct to jejunum
• Lithotripsy: disintegration of gallstones by shock waves
• Laparoscopic cholecystectomy: removal of
gallbladder through endoscopic procedure
• Laser cholecystectomy: removal of gallbladder using
laser

CHOLELITHIASIS
• Calculi, or gallstones, usually form in the gallbladder
from the solid constituents of bile; they vary greatly in
size, shape, and composition
• They are uncommon in children and young adults but
become increasingly prevalent after 40 years of age.
• The incidence of cholelithiasis increases thereafter to
such an extent that up to 50% of those over the age of
70 and over 50% of those over 80 will develop stones in
the bile tract.

RISK FACTORS FOR CHOLELITHIASIS
• Obesity
• Women, especially those who have had multiple
pregnancies or who are of Native American or U.S.
Southwestern Hispanic ethnicity
• Frequent changes in weight
• Rapid weight loss (leads to rapid development of
gallstones and high risk of symptomatic disease)
• Treatment with high-dose estrogen (ie, in prostate
cancer)
• Low-dose estrogen therapy—a small increase in the risk
of gallstones

RISK FACTORS FOR CHOLELITHIASIS
• Ileal resection or disease
• Cystic fibrosis
• Diabetes mellitus

CLINICAL MANIFESTATIONS
• Gallstones may be silent, producing no pain and only
mild gastrointestinal symptoms.
• The symptoms may be acute or chronic.
• Epigastric distress, such as fullness, abdominal
distention, and vague pain in the right upper quadrant of
the abdomen, may occur.
• This distress may follow a meal rich in fried or fatty
foods.

PAIN AND BILIARY COLIC
• If a gallstone obstructs the cystic duct, the gallbladder
becomes distended, inflamed, and eventually infected.
• The patient develops a fever and may have a palpable
abdominal mass.
• The patient may have biliary colic with excruciating upper
right abdominal pain that radiates to the back or right
shoulder, is usually associated with nausea and vomiting,
and is noticeable several hours after a heavy meal.
• The patient moves about restlessly, unable to find a
comfortable position. In some patients the pain is constant
rather than colicky.

JAUNDICE
• Jaundice occurs in a few patients with gallbladder
disease and usually occurs with obstruction of the
common bile duct.
• The bile, which is no longer carried to the duodenum, is
absorbed by the blood and gives the skin and mucous
membrane a yellow color.
• This is frequently accompanied by marked itching of the
skin.

CHANGES IN URINE AND STOOL COLOR
• The excretion of the bile pigments by the kidneys gives
the urine a very dark color.
• The feces, no longer colored with bile pigments, are
grayish, like putty, and usually described as clay-
colored.
VITAMIN DEFICIENCY
• Obstruction of bile flow also interferes with absorption of
the fatsoluble vitamins A, D, E, and K.
• Therefore, the patient may exhibit deficiencies of these
vitamins if biliary obstruction has been prolonged.

ASSESSMENT AND DIAGNOSTIC FINDINGS
• An abdominal x-ray may be obtained if gallbladder disease
is suggested to exclude other causes of symptoms.
• Ultrasonography has replaced oral cholecystography as
the diagnostic procedure of choice because it is rapid and
accurate and can be used in patients with liver dysfunction
and jaundice.
• Cholescintigraphy is used successfully in the diagnosis of
acute cholecystitis. In this procedure, a radioactive agent is
administered intravenously.
• Cholecystography is still used if ultrasound equipment is
not available or if the ultrasound results are inconclusive.

ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY
• This permits direct visualization of structures that could
once be seen only during laparotomy.
• The examination of the hepatobiliary system is carried
out via a side-viewing flexible fiberoptic endoscope
inserted into the esophagus to the descending
duodenum.
• Fluoroscopy and multiple x-rays are used during ERCP
to evaluate the presence and location of ductal stones.

NURSING IMPLICATIONS
• The procedure requires a cooperative patient to permit
insertion of the endoscope without damage to the
gastrointestinal tract structures, including the biliary tree.
• Before the procedure, the patient is given an explanation
of the procedure and his or her role in it.
• The patient takes nothing by mouth for several hours
before the procedure.
• Moderate sedation is used with this procedure, so the
sedated patient must be monitored closely.
• Medications such as glucagon or anticholinergics may
also be necessary to eliminate duodenal peristalsis to
make cannulation easier.

NURSING IMPLICATIONS
• The nurse observes closely for signs of respiratory and
central nervous system depression, hypotension,
oversedation, and vomiting (if glucagon is given).
• During ERCP, the nurse monitors intravenous fluids,
administers medications, and positions the patient.
• After the procedure, the nurse monitors the patient’s
condition, observing vital signs and monitoring for signs
of perforation or infection.
• The nurse also monitors the patient for side effects of
any medications received during the procedure and for
return of the gag and cough reflexes after the use of
local anesthetics.

PERCUTANEOUS TRANSHEPATIC CHOLANGIOGRAPHY
• Percutaneous transhepatic cholangiography involves the
injection of dye directly into the biliary tract.
• This procedure can be carried out even in the presence of
liver dysfunction and jaundice. It is useful for distinguishing
jaundice caused by liver disease (hepatocellular jaundice)
from that caused by biliary obstruction, for investigating the
gastrointestinal symptoms of a patient whose gallbladder
has been removed, for locating stones within the bile ducts,
and for diagnosing cancer involving the biliary system.
• This sterile procedure is performed under moderate
sedation on a patient who has been fasting; the patient
receives local anesthesia and intravenous sedation.

PERCUTANEOUS TRANSHEPATIC CHOLANGIOGRAPHY
• Coagulation parameters and platelet count should be
normal to minimize the risk for bleeding.
• Broad-spectrum antibiotics are administered during the
procedure due to the high prevalence of bacterial
colonization from obstructed biliary systems.

MEDICAL MANAGEMENT
• The major objectives of medical therapy are to reduce
the incidence of acute episodes of gallbladder pain and
cholecystitis by supportive and dietary management
and, if possible, to remove the cause of cholecystitis by
pharmacologic therapy, endoscopic procedures, or
surgical intervention.
• Most of the nonsurgical approaches, including lithotripsy
and dissolution of gallstones, provide only temporary
solutions to the problems associated with gallstones.
• Removal of the gallbladder (cholecystectomy) through
traditional surgical approaches was considered the
standard approach to management.

MEDICAL MANAGEMENT
• There is now widespread use of laparoscopic
cholecystectomy (removal of the gallbladder through a
small incision through the umbilicus).
• As a result, surgical risks have decreased, along with
the length of hospital stay and the long recovery period
associated with the standard surgical cholecystectomy.
Morphine typically is not ordered because it can
cause biliary spasms.

MEDICAL MANAGEMENT
NUTRITIONAL AND SUPPORTIVE THERAPY
• The diet immediately after an episode is usually limited
to low-fat liquids.
• The patient can stir powdered supplements high in
protein and carbohydrate into skim milk.
• Cooked fruits, rice or tapioca, lean meats, mashed
potatoes, non–gas-forming vegetables, bread, coffee, or
tea may be added as tolerated.
• The patient should avoid eggs, cream, pork, fried foods,
cheese and rich dressings, gas-forming vegetables, and
alcohol.

MEDICAL MANAGEMENT
NUTRITIONAL AND SUPPORTIVE THERAPY
• It is important to remind the patient that fatty foods may
bring on an episode.
• Dietary management may be the major mode of therapy
in patients who have had only dietary intolerance to fatty
foods and vague gastrointestinal symptoms.

MEDICAL MANAGEMENT
PHARMACOLOGIC THERAPY
• Ursodeoxycholic acid (UDCA) and chenodeoxycholic
acid (chenodiol or CDCA) have been used to dissolve
small, radiolucent gallstones composed primarily of
cholesterol. It acts by inhibiting the synthesis and
secretion of cholesterol, thereby desaturating bile.
Elderly clients can experience confusion and
even seizures when given meperidine (Demerol)
for pain control!

NONSURGICAL REMOVAL OF GALLSTONES
DISSOLVING GALLSTONES
• Several methods have been used to dissolve gallstones
by infusion of a solvent (mono-octanoin or methyl tertiary
butyl ether [MTBE]) into the gallbladder.
• The solvent can be infused through the following routes:
a tube or catheter inserted percutaneously directly into
the gallbladder; a tube or drain inserted through a T-tube
tract to dissolve stones not removed at the time of
surgery; an ERCP endoscope; or a transnasal biliary
catheter.
• This method of dissolution of stones is not widely used
in patients with gallstone disease.

STONE REMOVAL BY INSTRUMENTATION
• A catheter and instrument with a basket attached are
threaded through the T-tube tract or fistula formed at the
time of T-tube insertion; the basket is used to retrieve
and remove the stones lodged in the common bile duct.
• A second procedure involves the use of the ERCP
endoscope. After the endoscope is inserted, a cutting
instrument is passed through the endoscope into the
ampulla of Vater of the common bile duct.

EXTRACORPOREAL SHOCK-WAVE LITHOTRIPSY
• Extracorporeal shockwavetherapy has been used for
nonsurgical fragmentation of gallstones.
• This noninvasive procedure uses repeated shock waves
directed at the gallstones in the gallbladder or common
bile duct to fragment the stones.
• After the stones are gradually broken up, the stone
fragments pass from the gallbladder or common bile
duct spontaneously, are removed by endoscopy, or are
dissolved with oral bile acid or solvents.

INTRACORPOREAL LITHOTRIPSY
• A laser pulse is directed under fluoroscopic guidance
with the use of devices that can distinguish between
stones and tissue.
• The laser pulse produces rapid expansion and
disintegration of plasma on the stone surface, resulting
in a mechanical shock wave.
• Electrohydraulic lithotripsy uses a probe with two
electrodes that deliver electric sparks in rapid pulses,
creating expansion of the liquid environment
surrounding the gallstones.

SURGICAL MANAGEMENT
LAPAROSCOPIC CHOLECYSTECTOMY
• Laparoscopic cholecystectomy is performed through a
small incision or puncture made through the abdominal
wall in the umbilicus.
• The abdominal cavity is insufflated with carbon dioxide
to assist in inserting the laparoscope and to aid the
surgeon in visualizing the abdominal structures.
• The fiberoptic scope is inserted through the small
umbilical incision.

SURGICAL MANAGEMENT
CHOLECYSTECTOMY
• In this procedure, the gallbladder is removed through an
abdominal incision after the cystic duct and artery are
ligated.
• In some patients a drain may be placed close to the
gallbladder bed and brought out through a puncture
wound if there is a bile leak.

SURGICAL MANAGEMENT
MINI-CHOLECYSTECTOMY
• Mini-cholecystectomy is a surgical procedure in which
the gallbladder is removed through a small incision.
CHOLEDOCHOSTOMY
• Choledochostomy involves an incision into the common
duct, usually for removal of stones. After the stones have
been evacuated, a tube usually is inserted into the duct
for drainage of bile until edema subsides.
CHOLECYSTOSTOMY
• The gallbladder is surgically opened, the stones and the
bile or the purulent drainage are removed, and a
drainage tube is secured with a purse-string suture.

SURGICAL MANAGEMENT
PERCUTANEOUS CHOLECYSTOSTOMY
• Under local anesthesia, a fine needle is inserted through
the abdominal wall and liver edge into the gallbladder
under the guidance of ultrasound or computed
tomography.
• Bile is aspirated to ensure adequate placement of the
needle, and a catheter is inserted into the gallbladder to
decompress the biliary tract.
Alcohol use accounts for 80% of chronic
pancreatitis; however, do not automatically assume
that someone who has pancreatitis is an alcoholic.

Disorders of the Pancreas
ACUTE PANCREATITIS
• Acute pancreatitis ranges from a mild, self-limiting
disorder to a severe, rapidly fatal disease that does not
respond to any treatment.
• Mild acute pancreatitis is characterized by edema and
inflammation confined to the pancreas.
• Minimal organ dysfunction is present, and return to
normal usually occurs within 6 months.
• Although this is considered the milder form of
pancreatitis, the patient is acutely ill and at risk for
hypovolemic shock, fluid and electrolyte disturbances,
and sepsis.

• Severe abdominal pain is the major symptom of
pancreatitis that causes the patient to seek medical
care.
• Abdominal pain and tenderness and back pain result
from irritation and edema of the inflamed pancreas that
stimulate the nerve endings.
• Pain is frequently acute in onset, occurring 24 to 48
hours after a very heavy meal or alcohol ingestion, and it
may be diffuse and difficult to localize.
• Abdominal guarding is present.

ACUTE PANCREATITIS
• A more widespread and complete enzymatic digestion of
the gland characterizes severe acute pancreatitis.
• The tissue becomes necrotic, and the damage extends
into the retroperitoneal tissues.
• Local complications consist of pancreatic cysts or
abscesses and acute fluid collections in or near the
pancreas.
• Systemic complications, such as acute respiratory
distress syndrome, shock, disseminated intravascular
coagulopathy, and pleural effusion, can increase the
mortality rate to 50% or higher.

• A rigid or board-like abdomen may develop and is
generally an ominous sign; the abdomen may remain
soft in the absence of peritonitis.
• Ecchymosis in the flank or around the umbilicus may
indicate severe pancreatitis.
• Nausea and vomiting are common in acute pancreatitis.
• The emesis is usually gastric in origin but may also be
bile-stained.
• Fever, jaundice, mental confusion, and agitation also
may occur.

• Hypotension is typical and reflects hypovolemia and
shock caused by the loss of large amounts of protein-
rich fluid into the tissues and peritoneal cavity.
• The patient may develop tachycardia, cyanosis, and
cold, clammy skin in addition to hypotension.
• Acute renal failure is common.
• Respiratory distress and hypoxia are common, and the
patient may develop diffuse pulmonary infiltrates,
dyspnea, tachypnea, and abnormal blood gas values.
• Myocardial depression, hypocalcemia, hyperglycemia,
and disseminated intravascular coagulopathy (DIC) may
also occur with acute pancreatitis.

MEDICAL MANAGEMENT
• All oral intake is withheld to inhibit pancreatic stimulation
and secretion of pancreatic enzymes.
• Parenteral nutrition is usually an important part of
therapy, particularly in debilitated patients, because of
the extreme metabolic stress associated with acute
pancreatitis.
• Nasogastric suction may be used to relieve nausea and
vomiting, to decrease painful abdominal distention and
paralytic ileus, and to remove hydrochloric acid so that it
does not enter the duodenum and stimulate the
pancreas.

MEDICAL MANAGEMENT
• Histamine-2 (H2) antagonists (eg, cimetidine [Tagamet]
and ranitidine [Zantac]) may be prescribed to decrease
pancreatic activity by inhibiting HCl secretion.

PAIN MANAGEMENT
• Adequate pain medication is essential during the course
of acute pancreatitis to provide sufficient pain relief and
minimize restlessness, which may stimulate pancreatic
secretion further.
• Morphine and morphine derivatives are often avoided
because it has been thought that they cause spasm of
the sphincter of Oddi; meperidine (Demerol) is often
prescribed because it is less likely to cause spasm of the
sphincter.
• Antiemetic agents may be prescribed to prevent
vomiting.

INTENSIVE CARE
• Correction of fluid and blood loss and low albumin levels
is necessary to maintain fluid volume and prevent renal
failure.
• The patient is usually acutely ill and is monitored in the
intensive care unit, where hemodynamic monitoring and
arterial blood gas monitoring are initiated.
• Antibiotic agents may be prescribed if infection is
present; insulin may be required if significant
hyperglycemia occurs.

RESPIRATORY CARE
• Aggressive respiratory care is indicated because of the
high risk for elevation of the diaphragm, pulmonary
infiltrates and effusion, and atelectasis.
• Hypoxemia occurs in a significant number of patients
with acute pancreatitis even with normal x-ray findings.
• Respiratory care may range from close monitoring of
arterial blood gases to use of humidified oxygen to
intubation and mechanical ventilation.

BILIARY DRAINAGE
• Placement of biliary drains (for external drainage) and
stents (indwelling tubes) in the pancreatic duct through
endoscopy has been performed to reestablish drainage
of the pancreas. This has resulted in decreased pain
and increased weight gain.

SURGICAL INTERVENTION
• The patient who undergoes pancreatic surgery may
have multiple drains in place postoperatively as well as
a surgical incision that is left open for irrigation and
repacking every 2 to 3 days to remove necrotic debris.

POSTACUTE MANAGEMENT
• Antacids may be used when acute pancreatitis begins to
resolve.
• Oral feedings low in fat and protein are initiated
gradually.
• Caffeine and alcohol are eliminated from the diet.
• If the episode of pancreatitis occurred during treatment
with thiazide diuretics, corticosteroids, or oral
contraceptives, these medications are discontinued.

POSTACUTE MANAGEMENT
• Follow-up of the patient may include ultrasound, x-ray
studies, or ERCP to determine whether the pancreatitis
is resolving and to assess for abscesses and
pseudocysts.

The Patient with Acute Pancreatitis
ASSESSMENT
• The nurse assesses the presence of pain, its location,
its relationship to eating and to alcohol consumption,
and the effectiveness of pain relief measures.
• It also is important to assess the patient’s nutritional and
fluid status and history of gallbladder attacks and
alcohol use.
• A history of gastrointestinal problems, including nausea,
vomiting, diarrhea, and passage of fatty stools, is
elicited.
NURSING PROCESS:

ASSESSMENT
• The nurse assesses the abdomen for pain, tenderness,
guarding, and bowel sounds, noting the presence of a
board-like or soft abdomen.
• It also is important to assess respiratory status,
respiratory rate and pattern, and breath sounds.
• Normal and adventitious breath sounds and abnormal
findings on chest percussion, including dullness at the
bases of the lungs and abnormal tactile fremitus, are
documented.

ASSESSMENT
• The nurse assesses the emotional and psychological
status of the patient and family and their coping,
because they are often anxious about the severity of the
symptoms and the acuity of illness.

NURSING DIAGNOSES
• Acute pain related to inflammation, edema, distention of
the pancreas, and peritoneal irritation
• Ineffective breathing pattern related to severe pain,
pulmonary infiltrates, pleural effusion, atelectasis, and
elevated diaphragm
• Imbalanced nutrition, less than body requirements,
related to reduced food intake and increased metabolic
demands
• Impaired skin integrity related to poor nutritional status,
bed rest, and multiple drains and surgical wound

PLANNING AND GOALS
• The major goals for the patient include relief of pain and
discomfort, improved respiratory function, improved
nutritional status, maintenance of skin integrity, and
absence of complications.

NURSING INTERVENTIONS

CHRONIC PANCREATITIS
• Chronic pancreatitis is an inflammatory disorder
characterized by progressive anatomic and functional
destruction of the pancreas.
• As cells are replaced by fibrous tissue with repeated
attacks of pancreatitis, pressure within the pancreas
increases.
• The end result is mechanical obstruction of the
pancreatic and common bile ducts and the duodenum.
• Additionally, there is atrophy of the epithelium of the
ducts, inflammation, and destruction of the secreting
cells of the pancreas.

CHRONIC PANCREATITIS
• Excessive and prolonged consumption of alcohol
accounts for approximately 70% of the cases.
• The incidence of pancreatitis is 50 times greater in
alcoholics than in the nondrinking population.
• Damage to these cells is more likely to occur and to be
more severe in patients whose diets are poor in protein
content and either very high or very low in fat.

• Chronic pancreatitis is characterized by recurring
attacks of severe upper abdominal and back pain,
accompanied by vomiting.
• Weight loss is a major problem in chronic pancreatitis:
more than 75% of patients experience significant weight
loss, usually caused by decreased dietary intake
secondary to anorexia or fear that eating will precipitate
another attack.
• Malabsorption occurs late in the disease, when as little
as 10% of pancreatic function remains.

• As a result, digestion, especially of proteins and fats, is
impaired.
• The stools become frequent, frothy, and foul-smelling
because of impaired fat digestion, which results in stools
with a high fat content.

• ERCP is the most useful study in the diagnosis of chronic
pancreatitis.
• Various imaging procedures, including magnetic resonance
imaging, computed tomography, and ultrasound, have
been useful in the diagnostic evaluation of patients with
suspected pancreatic disorders.
• A glucose tolerance test evaluates pancreatic islet cell
function, information necessary for making decisions about
surgical resection of the pancreas.
• In contrast to the patient with acute pancreatitis, serum
amylase levels and the white blood cell count may not be
elevated significantly.

MEDICAL MANAGEMENT
• Endoscopy to remove pancreatic duct stones and stent
strictures may be effective in selected patients to
manage pain and relieve obstruction.
• Management of abdominal pain and discomfort is similar
to that of acute pancreatitis; however, the focus is
usually on the use of nonopioid methods to manage
pain.
• The physician, nurse, and dietitian emphasize to the
patient and family the importance of avoiding alcohol
and other foods that the patient has found tend to
produce abdominal pain and discomfort.

MEDICAL MANAGEMENT
• Diabetes mellitus resulting from dysfunction of the
pancreatic islet cells is treated with diet, insulin, or oral
antidiabetic agents.
• Pancreatic enzyme replacement is indicated in the
patient with malabsorption and steatorrhea.

SURGICAL MANAGEMENT
• Pancreaticojejunostomy (also referred to as Roux-en-
Y) with a side-to-side anastomosis or joining of the
pancreatic duct to the jejunum allows drainage of the
pancreatic secretions into the jejunum.
• Other surgical procedures may be performed for
different degrees and types of disease, ranging from
revision of the sphincter of the ampulla of Vater, to
internal drainage of a pancreatic cyst into the stomach,
to insertion of a stent, to wide resection or removal of
the pancreas.

SURGICAL MANAGEMENT
• A Whipple resection (pancreaticoduodenectomy) has
been carried out to relieve the pain of chronic
pancreatitis.
• Autotransplantation or implantation of the patient’s
pancreatic islet cells has been attempted to preserve the
endocrine function of the pancreas in patients who have
undergone total pancreatectomy.

PANCREATIC CYSTS
• As a result of the local necrosis that occurs at the time of
acute pancreatitis, collections of fluid may form in the
vicinity of the pancreas. These become walled off by
fibrous tissue and are called pancreatic pseudocysts.
• Diagnosis of pancreatic cysts and pseudocysts is made
by ultrasound, computed tomography, and ERCP.

CANCER OF THE PANCREAS
• Cigarette smoking, exposure to industrial chemicals or
toxins in the environment, and a diet high in fat, meat, or
both are associated with pancreatic
• Diabetes mellitus, chronic pancreatitis, and hereditary
pancreatitis are also associated with pancreatic cancer.
• The pancreas can also be the site of metastasis from
other tumors.

• Pain, jaundice, or both are present in more than 90% of
patients and, along with weight loss, are considered
classic signs of pancreatic carcinoma.
• Other signs include rapid, profound, and progressive
weight loss as well as vague upper or midabdominal
pain or discomfort that is unrelated to any
gastrointestinal function and is often difficult to describe.
• Such discomfort radiates as a boring pain in the
midback and is unrelated to posture or activity. Relief
may be obtained by sitting up and leaning forward, or
accentuated when lying supine.

• The formation of ascites is common.
• An important sign, when present, is the onset of
symptoms of insulin deficiency: glucosuria,
hyperglycemia, and abnormal glucose tolerance.
• Meals often aggravate epigastric pain, which usually
occurs before the appearance of jaundice and pruritus.

• Magnetic resonance imaging and computed tomography
are used to identify the presence of pancreatic tumors.
• Gastrointestinal x-ray findings may demonstrate
deformities in adjacent viscera caused by the impinging
pancreatic mass.
• Percutaneous fine-needle aspiration biopsy of the
pancreas is nused to diagnose pancreatic tumors and
confirm the diagnosis in patients whose tumors are not
resectable, eliminating the stress and postoperative pain
of ineffective surgery.

• Percutaneous transhepatic cholangiography is another
procedure that may be performed to identify obstructions
of the biliary tract by a pancreatic tumor.
• Several tumor markers (eg, CA 19-9, CEA, DU-PAN-2)
may be used in the diagnostic workup, but they are
nonspecific for pancreatic carcinoma.
• Angiography, computed tomography, and laparoscopy
may be performed to determine whether the tumor can
be removed surgically.
• Intraoperative ultrasonography has been used to
determine if there is metastatic disease to other organs.

MEDICAL MANAGEMENT
• If the patient undergoes surgery, intraoperative radiation
therapy (IORT) may be used to deliver a high dose of
radiation to the tumor with minimal injury to other
tissues.
• IORT may also be helpful in relief of pain.
• Interstitial implantation of radioactive sources has also
been used, although the rate of complications is high.
• A large biliary stent inserted percutaneously or by
endoscopy may be used to relievemjaundice.

NURSING MANAGEMENT
• Pain management and attention to nutritional
requirements are important nursing measures to
improve the level of comfort.
• Skin care and nursing measures are directed toward
relief of pain and discomfort associated with jaundice,
anorexia, and profound weight loss.
• Specialty mattresses are beneficial and protect bony
prominences from pressure.
• Pain associated with pancreatic cancer may be severe
and may require liberal use of opioids; patient controlled
analgesia should be considered for the patient with
severe, escalating pain.

NURSING MANAGEMENT
• Because of the poor prognosis and likelihood of short
survival, end-of-life preferences are discussed and
honored.
• If appropriate, the nurse refers the patient to hospice
care.

TUMORS OF THE HEAD OF THE PANCREAS
• Sixty to eighty percent of pancreatic tumors occur in the
head of the pancreas.
• Tumors in this region of the pancreas obstruct the
common bile duct where the duct passes through the
head of the pancreas to join the pancreatic duct and
empty at the ampulla of Vater into the duodenum.
• The tumors producing the obstruction may arise from
the pancreas, the common bile duct, or the ampulla of
Vater.

• The obstructed flow of bile produces jaundice, clay-colored
stools, and dark urine.
• Malabsorption of nutrients and fat-soluble vitamins may
result from obstruction by the tumor to entry of bile in the
gastrointestinal tract.
• Abdominal discomfort or pain and pruritus may be noted,
along with anorexia, weight loss, and malaise.
• The jaundice of this disease must be differentiated from
that due to a biliary obstruction caused by a gallstone in
the common duct, which is usually intermittent and appears
typically in obese patients, most often women, who have
had previous symptoms of gallbladder disease.

• Diagnostic studies may include duodenography,
angiography by hepatic or celiac artery catheterization,
pancreatic scanning, percutaneous transhepatic
cholangiography, ERCP, and percutaneous needle
biopsy of the pancreas.
• Results of a biopsy of the pancreas may aid in the
diagnosis.

MEDICAL MANAGEMENT
• A diet high in protein along with pancreatic enzymes is
often prescribed.
• Preoperative preparation includes adequate hydration,
correction of prothrombin deficiency with vitamin K, and
treatment of anemia to minimize postoperative
complications.
• Parenteral nutrition and blood component therapy are
frequently required.
• A biliary-enteric shunt may be performed to relieve the
jaundice and, perhaps, to provide time for a thorough
diagnostic evaluation.

MEDICAL MANAGEMENT
• Total pancreatectomy (removal of the pancreas) may
be performed if there is no evidence of direct extension
of the tumor to adjacent tissues or regional lymph
nodes.
• A pancreaticoduodenectomy (Whipple’s procedure or
resection) is used for potentially resectable cancer of the
head of the pancreas. This procedure involves removal
of the gallbladder, distal portion of the stomach,
duodenum, head of the pancreas, and common bile duct
and anastomosis of the remaining pancreas and
stomach to the jejunum.

MEDICAL MANAGEMENT
• When the tumor cannot be excised, the jaundice may be
relieved by diverting the bile flow into the jejunum by
anastomosing the jejunum to the gallbladder, a
procedure known as cholecystojejunostomy.
• The postoperative management of patients who have
undergone a pancreatectomy or a
pancreaticoduodenectomy is similar to the management
of patients after extensive gastrointestinal and biliary
surgery.
• A nasogastric tube and suction and parenteral nutrition
allow the gastrointestinal tract to rest while promoting
adequate nutrition.

NURSING MANAGEMENT
• Preoperatively and postoperatively, nursing care is
directed toward promoting patient comfort, preventing
complications, and assisting the patient to return to and
maintain as normal and comfortable a life as possible.
• The nurse closely monitors the patient in the intensive
care unit after surgery; the patient will have multiple
intravenous and arterial lines in place for fluid and blood
replacement as well as for monitoring arterial pressures,
and is on a mechanical ventilator in the immediate
postoperative period.

NURSING MANAGEMENT
• It is important to give careful attention to changes in vital
signs, arterial blood gases and pressures, pulse
oximetry, laboratory values, and urine output.
• The nurse must also consider the patient’s compromised
nutritional status and risk for bleeding.
• Although the patient’s physiologic status is the focus of
the health care team in the immediate postoperative
period, the patient’s psychological and emotional state
must be considered, along with that of the family.
• The patient has undergone major and risky surgery and
is critically ill; thus, anxiety and depression may affect
recovery.

NURSING MANAGEMENT
• The immediate and long-term outcome of this extensive
surgical resection is uncertain, and the patient and
family require emotional support and understanding in
the critical and stressful preoperative and postoperative
periods.

PANCREATIC ISLET TUMORS
• At least two types of tumors of the pancreatic islet cells
are known: those that secrete insulin (insulinoma) and
those in which insulin secretion is not increased
(―nonfunctioning‖ islet cell cancer).
• Insulinomas produce hypersecretion of insulin and
cause an excessive rate of glucose metabolism. The
resulting hypoglycemia may produce symptoms of
weakness, mental confusion, and seizures.
• The 5-hour glucose tolerance test is helpful in
diagnosing insulinoma and in distinguishing it from other
causes of hypoglycemia.

SURGICAL MANAGEMENT
• When a tumor of the islet cells has been diagnosed,
surgical treatmentmwith removal of the tumor usually is
recommended.
• In some patients, symptoms may be produced by simple
hypertrophy of this tissue rather than a tumor of the islet
cells. In such cases, a partial pancreatectomy (removal
of the tail and part of the body of the pancreas) is
performed.

NURSING MANAGEMENT
• In preparing the patient for surgery, the nurse must be
alert for symptoms of hypoglycemia and be ready to
administer glucose as prescribed if symptoms occur.
• Postoperatively, the nursing management is the same as
that after other upper abdominal surgical procedures,
with special emphasis on monitoring serum glucose
levels.
• Patient teaching is determined by the extent of surgery
and the alterations in pancreatic function that result.

HYPERINSULINISM
• Hyperinsulinism results from overproduction of insulin by
the pancreatic islets.
• Symptoms resemble those of excessive doses of insulin
and are attributable to the same mechanism, an abnormal
reduction in blood glucose levels.
• Clinically, it is characterized by episodes during which the
patient experiences unusualmhunger, nervousness,
sweating, headache, and faintness; in severe cases,
seizures and episodes of unconsciousness may occur.
• The findings at the time of surgery or at autopsy may
indicate hyperplasia of the islets of Langerhans or a benign
or malignant tumor involving the islets and capable of
producing large amounts of insulin.

HYPERINSULINISM
• Surgical removal of the hyperplastic or neoplastic tissue
from the pancreas is the only successful method of
treatment.
• About 15% of patients with spontaneous or functional
hypoglycemia eventually develop diabetes mellitus.

ULCEROGENIC TUMORS
• Some tumors of the islets of Langerhans are associated
with hypersecretion of gastric acid that produces ulcers
in the stomach, duodenum, and jejunum. The result is
referred to as Zollinger- Ellison syndrome.
• The hypersecretion is so great that even after partial
gastric resection, enough acid is produced to cause
further ulceration.
• In many patients, a total gastrectomy may be necessary
to reduce the secretion of gastric acid sufficiently to
prevent further ulceration.
