gallstones pathophysiology
Gallstones – Pathophysiology
  • Cholesterol, ordinarily insoluble in water, comes into solution by forming vesicles with phospholipids
  • If ratio of cholesterol, phospholipids, and bile salts altered, cholesterol crystals may form
  • Gallstone formation involves a variety of factors:
    • Cholesterol supersaturation
    • Mucinhypersecretion by the gallbladder mucosa creates a viscoelastic gel that fosters nucleation.
    • Bile stasis
  • Risk factors:
  • Obesity
  • Female gender
  • Parity
  • Maternal family history ( ABCB4 , CYP7A1)
  • Ethnic predilection (Hispanic, Native americans)
  • Increasing age
  • Rapid weight loss
  • Risk factors:

Ileal disease

Lipid abnormalities (high TG, low LDL)

Medications (contraceptives, postmenopausal

estrogens, lipid lowering agents

fibric acid derivated)

  • TPN

מצבים שכיחים
  • Cholelithiasis
  • Biliary colic
  • Hydrops
  • Empyema
  • Choledocholithiasis
  • Acute Cholecystitis
  • Ascending Cholangitis
gallstones types
Gallstones – Types
  • Two main types:
    • Cholesterol stones (85%)
    • Pigment stones (15%) occur in 2 subtypes—

brown and black.

      • Black stones result when excess bilirubin enters the bile and polymerizes into calcium bilirubinate (chronic hemolysis)
      • Brown stones are made up of calcium bilirubinate and calcium-soaps. Bacteria involved in formation via secretion of beta glucuronidase and phospholipase
gallstones natural history
Gallstones – Natural History
  • 80% of patients, gallstones are clinically silent
  • 20% of patients develop symptoms over 15-20 years (1-2% per year)
  • 50-70% continued to have symptoms and complications
  • More than 90% of complications are preceded by biliary colic
biliary colic
Biliary Colic
  • Intermittent obstruction of the cystic duct, no inflammation of GB
  • Severe epigastric/ RUQ pain growing over 15 min and remaining constant up to 3h
  • Frequency of attacks varies
  • Normal examination
  • Lab tests usually normal
  • DS: US, EUS
  • Natural history: 30% have no further symptoms

50% continue symptoms in 2y

acute calculous cholecystitis
Acute Calculous Cholecystitis
  • Impacted stone in the cystic duct
  • 75% are preceded by attacks of biliary colic
  • Visceral epigastric pain – mod to severe, irradiated to RUQ, back, shoulder, chest and lasting > 6 h
  • Fever, Right subcostal tenderness with inspiratory arrest

( Murphy’s sign) , palpable GB

  • Leucocytosis, mild elevation of BIL, Amylase
  • 50% resolve spontaneously in 7-10 days without surgery
  • DS: US, EUS, CT
  • 10% are complicated by perforation.
empyema mucocoele
Empyema / Mucocoele
  • Mucocele refers to an overdistended gallbladder filled with mucoid or clear and watery content.
  • Empyema refers to a gallbladder filled with pus due to acute cholecystitis
  • Intermittent obstruction of CBD
  • Often symptomatic – indistinguishable from biliary colic
  • Predisposed to acute cholangitis and pancreatitis
  • Signs : jaundice with pain.
  • Investigations
    • Elevated BIL, transient spike in Tranaaminases / Amylase,
    • US, EUS, CT
  • Treatment
    • ERCP - Endoscopic Retrograde CholangioPancreatography
ascending cholangitis
Ascending Cholangitis
  • Impacted stone in CBD causing bile stasis
  • Bacterial superinfection
  • Charcot’s triad : pain, jaundice, fever – 70%
  • Mental confusion, hypotension, RUQ tenderness
  • Jaundice (>80%)
  • Peritoneal signs (15%)

  • Emergent decompression of the CBD


acute biliary pancreatitis
Acute biliary pancreatitis
    • Pancreatic duct obstruction or chemical inflammation
    • Signs - Variable – None to Sepsis

(Severe pain, fever, tachycardia, low BP),

Jaundice, acute abdomen

  • Investigations
    • Bloods – U&E, FBC, LFT, Amylase, CRP
    • Ultrasound of abdomen
    • MRCP
    • CT Pancreas
  • Treatment Supportive / ERCP
gallstone ileus
Gallstone ileus
  • Obstruction of the small bowel by a large gallstone
    • A stone ulcerates through the gallbladder into the duodenum and causes obstruction at the terminal ileum/rt colon
  • Symptoms : SBO - vomiting, abdominal pain, distension, obstructive bowel sounds
  • Investigations: X-ray, US/CT - air in CBD
  • Treatment : Laparotomy and removal of stone from small bowel and cholecystectomy.
mirizzi s syndrome
Mirizzi’s Syndrome

Inflammatory phenomenon secondary to a pressure ulcer caused by an impacted gallstone at the gallbladder infundibulum

The impacted gallstone causes first external obstruction of the CBD

Eventually erodes into the bile duct evolving into a cholecystocholedochal fistula with different degrees of communication between the GB and CBD

lemmmel s syndrome
Lemmmel’s Syndrome

Duodenal diverticula syndrome

Secondary to extrinsic compression by periampullarydiverticula in the absence of additional pathology (cholelithiasis, tumor)

  • The hypothesized mechanisms:
  • Alterations of the papillary motility
  • Bacterial contamination
  • Extrinsic compression of the Main biliary tract
acute acalculous cholecystitis
Acute Acalculous Cholecystitis
  • Presence of an inflamed gallbladder in the absence of an obstructed cystic or common bile duct
  • Typically occurs in the setting of a critically ill patient (eg, severe burns, multiple traumas, lengthy postoperative care, prolonged intensive care)
  • Accounts for 5% of cholecystectomies
  • Etiologyis thought to have ischemic basis, and gangrenous gallbladder may result
  • Increased rate of complications and mortality
  • An uncommon subtype known as acute emphysematous cholecystitis generally is caused by infection with clostridial organisms and occlusion of the cystic artery associated with atherosclerotic vascular disease and, often, diabetes.
  • Laparoscopic cholecystectomy standard of care
  • Timing

biliary stricture non cancerous cause s
Biliary Stricture – Non Cancerous Causes

Noncancerous causes of bile duct stricture include:

  • Injury to the bile ducts during surgery for gallbladder removal
  • Pancreatitis (inflammation of the pancreas)
  • Primary sclerosingcholangitis
  • Gallstones (benign CBD stricture, papillary


  • Blunt trauma to the abdomen
primary sclerosing cholangitis
Primary Sclerosing Cholangitis
  • Chronic cholestatic biliary disease characterized by non-suppurativeinflammation and fibrosis of the biliary ductalsystem
  • Cause is unknown but is associated with autoimmune inflammatory diseases, such as chronic ulcerative colitis and Crohn’s colitis, and rare conditions, such as Riedel thyroiditis and retroperitoneal fibrosis
  • Most patients present with fatigue and pruritus and, occasionally, jaundice
  • Natural history is variable but involves progressive destruction of the bile ducts, leading to cirrhosis and liver failure
  • Clinical features of cholangitis (ie, fever, right upper quadrant pain, jaundice) are uncommon unless the biliary system has been instrumented.

Medical Care

  • Chronic progressive disease with no curative medical therapy
  • Goals of medical management are to treat the symptoms and to prevent or treat the known complications
  • Liver transplantation is the only effective therapy and is indicated in end-stage liver disease.

Surgical Care

  • Indications for liver transplantation include variceal bleed or portal gastropathy, intractable ascites, recurrent cholangitis, progressive muscle wasting, and hepatic encephalopathy.
  • Recurs in 15-20% of patients after transplantation.
primary biliary cirrhosis
Primary Biliary Cirrhosis
  • Progressive cholestatic biliary disease that presents with fatigue and itching or asymptomatic elevation of the alkaline phosphatase.
  • Jaundice develops with progressive destruction of bile ductules that eventually leads to liver cirrhosis and hepatic failure.
  • Autoimmune illness has a familial predisposition

Antimitochondrial antibodies (AMA) are present in 95% of patients

Goals of treatment are to slow the progression rate of the disease and to alleviate the symptoms (eg, pruritus, osteoporosis, sicca syndrome)

Liver transplantation appears to be the only life-saving procedure.


Endoscopic retrograde

cholangiopancreatography (ERCP)

  • Endoscopictube is placed into the patient’s mouth, through the stomach, and into the duodenal portion of the small intestine.
