Gallstone Pathogenesis
• Bile = bile salts (acids), phospholipids, cholesterol, conjugated bilirubin, water, ions
• Pathogenesis involves 3 stages:1. cholesterol supersaturation in bile2. crystal nucleation3. stone growth

GallstonesClinical Presentation
– RUQ (or epigastric) pain (colicky, referring to back) – Jaundice– Intestinal obstruction- Fever- Nausea- Vomiting
GallstonesComplications
– Inflammation of the gallbladder (cholecystitis),– Inflammation of the bile duct (cholangitis)– Inflammation of the pancreas (biliary pancreatitis)– Obstruction of the intestine (gallstone ileus)– Obstructive jaundice– Malignancies
Symptomatic cholelithiasis• Biliary colic• Pain: 1-5 hrs, rarely > 24hrs• Ultrasound reveals gallstones• Treatment: Laparoscopic cholecystectomy
Chronic calculous cholecystitis
• Recurrent inflammatory process• Overtime, leads to scarring/wall thickening of
the gallbladder• Treatment: laparoscopic cholecystectomy
Acute calculous cholecystitis• Persistent cystic duct obstruction leads to GB
distension, wall inflammation & edema• May be associated with empyema, gangrene,
rupture of the GB• Pain usually + >24hrs • Palpable/tender or even visible RUQ mass• US: Thickened wall (DD!!: CHI, hypoalbuminemia) • Nuclear HIDA : nonfilling of GB• Treatment: Cholecystectomy (early or delayed);
cholecystostomy (rarely)
Acute acalculous cholecystitis
• 5-10% • Critically ill patients or prolonged TPN• Complications: gangrene, empyema,
perforation• Decreased enteral stimulation = low
cholecystokinin = gallbladder stasis • Emergent cholecystectomy• Or cholecystostomy and delayed
cholecystectomy
Choledocholithiasis
• Gallstones within common bile duct (or common hepatic duct
• DD: cholelithiasis, hepatitis, sclerosing cholangitis, cholangiocarcinoma
CholedocholithiasisManagement
• ERCP• Laparoscopic procedures– Trancystic exploration– Laparoscopic choledochotomy
• Open procedures

CholedocholithiasisManagement
ERCP• Success rate for the clearance of
choledocholithiasis is 70-90%
Overall complication rate: 5% to 10%Mortality: 0.02% to 0.5%
Freeman et al. N Engl J Med 1996Cotton PB et al. Gastrointest Endosc 1991
ERCP
RisksEarly: Perforation, bleeding, infection, pancreatitis
Late: Papillary stenosis, stricture due to cautery,
cholangitis, biliary malignancy due to enterobiliary reflux
ERCP
Risk of malignancy transformation
ERCP: 27 708ES: 11,617 1976 - 2003
The risk of malignancy in the bile ducts, liver, or pancreas is elevated after ERCP in benign disease. However, endoscopic sphincterotomy does not seem to affect this risk.
Luo et al. Clin Gastroenterol Hepatol 2008
ERCP
Difficult bile duct stones at ERCP
• Stones >15 mm,• Intrahepatic stones• Multiple stones• Impacted stones• Stone proximal to a biliary stricture• Tortuous bile duct• Duodenal diverticulum• Prior Billroth II• Prior surgical duodenotomy
Management of preoperatively “suspected” CBD stones
• Jaundice• Elevated cholestatic liver function tests• History of pancreatitis• Dilated biliary system on radiographic imaging
Negative ERCP: 40-70% !!Kroh M. Surg Clin North Am 2008
Reducing negative ERCP
• EUS• MRCP• Intraoperative cholangiography• Laparoscopic US
Endoscopic Ultrasound
Meta-analysis including 27 papers
Sensitivity: 0.94; speficifity: 0.95EUS should be used to select patients for a
therapeutic ERCP and to minimize the risk of complications associated with unnecessary diagnostic ERCP
Tse et al. Gastrointest Endosc 2008
MRCP
Detection of CBD stones before LC
Sensitivity: 90% Speficifity: 96%
Boraschi et al. Acta Radiologica 2002
IOC
Routine IOC or Selective IOC for CBD stones
There would be only 1.5%of the patients having missed CBD stones if selective IOC was to be performed
Singh et al. Aust NZ Surg 2000
Laparoscopic US
Less invasive, quick, no radiation,
Identification of CBD stonesSensitivity 92%, Specificity 100%
Could replace IOC
Management of diagnosed CBD stones
PREOPERATIVE PERIOD
No particular difficulty /contraindication ERCP
DifficultiesFailed attempts SurgeryContraindications
Management of diagnosed CBD stones
DIAGNOSIS OF CBD STONES DURING OP• Experience of the surgeon• Number, size, type of the CBD stones
Management of diagnosed CBD stones
DIAGNOSIS OF CBD STONES DURING OP
Options• Laparoscopic trancystic CBD exploration• Laparoscopic choledochotomy• Open CBD exploration• Postoperative ERCP
Laparoscopic trancystic CBD exploration
• CBD is left intact• Successful CBD clearance in 60-70%
• Usually requires specific instruments• Requires experience• Not appropriate in multiple large stones, small caliber
CD, impacted stones etc.
Laparoscopic Choledochotomy
• Effective exploration• Enables bilioenteric drainage / decompression• Residual stones may be removed via T-tube tract (4 -
6w later)
• Compications of T-tube or bilioenteric anastomosis• Requires advanced laparoscopic skills
Open CBD exploration
• Unsuccessful transcystic CBD expl• Unsuccessful laparoscopic choledochotomy• Multiple (>10) stones• Large stones• Impacted stones• Failed or unavailable ERCP
Management of diagnosed CBD stones
POSTOPERATIVE PERIOD
No particular difficulty /contraindication ERCP
DifficultiesFailed attempts SurgeryContraindications
Stone removal from T-tube tract
Laparoscopic bile duct exploration
Cholangitis
• Infection of the bile ducts (CBD obstruction due to stones, strictures, tumors, bilioenteric anastomoses ascariasis etc.)
• Charcot’s triad 70% +: fever, RUQ pain, jaundice • May lead to life-threatening sepsis and septic shock
(Reynolds’ pentad= Charcot’s triad + hypotension and altered mental status)
Treatment• Broad-spectrum antibiotherapy• Emergent decompression via ERCP or perc
transhepatic cholangiogram (PTC)• Surgery
Gallstone pancreatitis
• Acute pancreatitis is related to galltones in most cases in Turkey
• Pathophysiology – Reflux of bile into pancreatic duct and/or
obstruction of ampulla by stone
Tretament: • Resuscitation• ERC:P stone extraction/sphincterotomy• Cholecystectomy during hospital stay
