Disclosures
• I have no conflicting financial relationships
with any of the devices, drugs or organs that I
will be discussing.
• However, like many general surgeons, the
gallbladder is largely responsible for educating
my children, and so anything I say could be
skewed by that relationship.
Objectives
• Understand the many varied presentations of
gallstone disease and their management.
• Understand the workup and treatment of
acalculous gallbladder disease.
• Understand the management of gallbladder
disease in the critical care setting.
Introduction
• It hardly seems reasonable to have gallbladder disease
be part of “What’s New In My Specialty?”.
• Gallstones go back at least as far as ~1000 BC. An
Egyptian mummy—an apparent priestess—has been
found to have gallstones.
• First recognition of gallstones in life is credited to
Alexander of Tralles in the 6th century BC.
• John Stough Bobbs (1809-1870)—first cholecystotomy
in 1867.
• Carl Langenbuch (1846-1901)—first cholecystectomy in
1882—recognizing that horses, elephants and rats
don’t have gallbladders.
Introduction
• The last really big innovation for gallbladder
disease was laparoscopic cholecystectomy, first
performed in France in 1987.
• Perhaps MRCP, developed in 1991, could be
considered a major development, but that was 22
years ago.
• Single-port cholecystectomy
– No good evidence that it makes much difference
• NOTES—Natural Orifice Translumenal Endoscopic
Surgery
– Not likely to become common

Scope of Gallbladder Disease and
Cholecystectomy
• Among the most common surgical procedure performed—about
500,000 per year.
• Prevalence of gallstones estimated at 10-20% over a lifetime.
• A patient base of almost 7000 patients
– 1988—1.35 cholecystectomies per thousand
– 1992—2.15 cholecystectomies per thousand
– 59% increase!
• JAMA. 1993;270:1429-1432
• Today—1.68 just in ambulatory surgery centers, perhaps up to 3.00
in all.
• Multiply 2.15 times 75 years of life and that is 160 gallbladders
removed per thousand over a lifetime. (16%)
• By Comparison—Northern Ireland—1.01 per thousand in 2009.
Scope of Gallbladder Disease and
Cholecystectomy
• Local data
• January 2013: 80 cholecystectomies in Ogden
– Approximately 1000 cholecystectomies/year
– 9291 births in Ogden in 2012
• Approximately 10% of people in Northern
Utah will lose their gallbladders before they
die.
Scope of Gallbladder Disease and
Cholecystectomy
• Description of old Boitnott study.
• Taken together we can conclude that in the
laparoscopic era we are taking out more
gallbladders and less sick gallbladders.
• Data from 2013—11/40 consecutive
gallbladders at both hospitals did not have
stones. (28%)
Implications of Increasing
Cholecystectomy
• Are we reducing complications of gallbladder
disease?
• Maybe??
– A nationwide study of multiple databases concluded
that Acute Cholecystitis as a reason for hospital
admission declined 14% from 2000-2009.
– Is this related to more management of acute
cholecystitis as an outpatient?
– Peery, AF, et al. Burden of Gastrointestinal Disease in
the United States: 2012 Update.
Gastroenterology. 2012;143(5):1179-1187.
Implications of Increasing
Cholecystectomy
• Acute Pancreatitis
– 30% increase in admissions for acute pancreatitis
from 2000-2009.
– 40-50% would be “gallstone pancreatitis”
• Taken together, despite a decrease in acute
cholecystitis, with the increase in pancreatitis,
complications from gallstones are probably
not decreasing despite increasing
cholecystectomy.
Implications of Increasing
Cholecystectomy
• Bile Duct Injury
– Rate of bile duct injury is at a fairly constant 0.1-0.2%
– If 28% of 1000 gallbladders per year are not “that sick”, then every 2-4
years we are causing an additional bile duct injury in Weber County .
• Colon Cancer
– Several studies show an increased risk of colorectal cancer after
cholecystectomy in the 10-40% range.
– If cholecystectomy increases risk of colon cancer from 5-6% (a 20%
increase), then about 2 patients a year with gallbladders that are “not
that sick” are getting needless colorectal cancer in Weber County.
• Overall, increasing rates of cholecystectomy are not necessarily
beneficial to the population as a whole, which could become fairly
important as we move in the direction of accountable and/or
bundled care models for a population instead of individual patients.
Manifestations of Gallstone Disease
Sleisenger and Fordtran: Gastrointestinal and Liver Disease: Pathophysiology/Diagnosis/Management , Ninth Edition
Mark Feldman, Lawrence S. Friedman, and Lawrence J. Brandt, 2010.
Manifestations of Gallstone Disease
•
•
•
•
Biliary Colic and Chronic Cholecystitis
Most common indication for cholecystectomy
Intermittent cystic duct obstruction
Presence of stones on ultrasound and
symptoms are appropriate for
cholecystectomy without any further workup.
• Eventually symptoms tend to escalate.
• Atypical presentation in the elderly
Manifestations of Gallstone Disease
• Acute Cholecystitis
– 226,000 admissions and 959 deaths in 2009
•
•
•
•
•
Persistent Cystic Duct Obstruction
Charcot’s triad
Ultrasound for diagnosis
HIDAscan in difficult cases
Expeditious cholecystectomy
Manifestations of Gallstone Disease
• Choledocholithiasis and Cholangitis
– It is estimated that 5-10% of patients will have CBD
stones at time of cholecystectomy.
– Probably 90% of these pass without intervention.
– Nevertheless, approximately 50,000 admissions
• Painful Jaundice +/- Fever
• Reynold’s Pentad
• Expeditious Therapeutic Cholangiogram—
Cholecystectomy is actually optional. 5% per
year will have further trouble.
• Note Gastric Bypass Population
Manifestations of Gallstone Disease
• Gallstone Pancreatitis
– Perhaps 120,000 admissions per year.
– Perhaps 1200 deaths.
• Since the gallbladder has no Constitutional
rights, it is often appropriately removed in the
absence of another cause of acute
pancreatitis.
Manifestations of Gallstone Disease
• Gallstone Ileus
• Gallbladder Cancer
– Fortunately, only 3300 cases in 2008
– Many are incidental, but 2000 deaths per year.
Manifestations of Gallstone Disease
• Asymptomatic Gallstones
– 10% will have symptoms after 5 years.
– 20% after 20 years.
• Cholecystectomy for:
–
–
–
–
–
–
–
Pediatric population
Pigmented stones (Hemolytic anemia)
“Already there”
Stones greater than 3 cms
Extended time away from reliable medical care
Bariatric surgery—30% develop stones
? Diabetes
Gallbladder Disease in Critically Ill
Patients
• 2 Scenarios
• Presentation with acute cholecystitis and
becoming critically ill.
– Fortunately rare.
– Expeditious cholecystectomy usually definitive.
Gallbladder Disease in Critically Ill
Patients
• Presentation with critical illness and
developing acute calculous or acalculous
cholecystitis.
• 5-10% of cholecystectomies
• Seen in trauma, burn, and other critically ill
patients.
• Tend to be men and older
• Treatment can be surgical or percutaneous
drainage.
Gallbladder Polyps
• A somewhat common incidental finding.
• The standard of care is cholecystectomy at
10mm.
• The question is what to do in the symptomatic
patient.
Cholesterolosis
• An acquired histologic abnormality of the gallbladder
epithelium characterized by excessive accumulation of
cholesterol esters and triglyceride within epithelial
macrophages.
• Present on 12% of autopsy specimens and 18% of
cholecystectomy specimens.
• It does not clearly cause symptoms but has been
implicated in acalculous biliary pain in which patients
seem to have better results when this is found.
• Also implicated in idiopathic recurrent pancreatitis.
Cholesterolosis
Chronic Acalculous Cholecystitis AKA
Biliary Dyskinesia
• Different than acutely ill discussed above.
• Ultrasound accuracy exceeds 95% and rarely
misses stones larger than 2mm.
• “Microlithiasis” or presence of cholesterol
crystals in bile does exist.
Work up of Gallstone-negative “Biliary
Symptoms”
• HIDAscan
– In healthy volunteers, the average ejection fraction is 75%
and virtually all exceed 35%, which is generally the
threshold for normal on these scans.
– This has become very popular and is often done
immediately after a negative ultrasound which makes the
test less predictive.
– With an abnormal test, cholecystectomy will show some
gallbladder inflammation in 90% and cholesterolosis in
30%.
– 65-80% will have improvement in symptoms, however up
to 50% will eventually have pain relief without surgery.
– Comment about “Hyperkinetic Gallbladder”.
Work up of gallstone negative “biliary
symptoms”
• CT Scan
• Very good at excluding other causes of
abdominal pain
• Rarely adds much to gallbladder diagnosis
unless a thickened wall is seen.
Work up of gallstone negative “biliary
symptoms”
• MRCP
• Another way to look for gallstones
• Very good non-invasive way to look for biliary
and pancreatic ductal anomalies including
pancreas divisum and common bile duct cysts.
Work up of gallstone negative “biliary
symptoms”
• ERCP
• Although invasive, a very good look at ductal
anatomy.
• Can allow for stenting.
• Can do manometry, but difficult.

Conclusions
• Gallbladder Disease is common and highly
variable in its presentation and treatment.
• A thoughtful understanding and approach to
the various complications of gallbladder
disease can streamline diagnosis and therapy.
• We probably take out too many gallbladders.
