Cholelithiasis and Biliary Colic

Written & clinically reviewed by Ryan Busch, PA-C · Updated August 2026 · Report an error

Gallstones in the gallbladder; transient cystic duct obstruction causes episodic RUQ pain.

Also known as: cholelithiasis, gallstones, biliary colic, symptomatic gallstone disease

Overview

Cholelithiasis: presence of gallstones in the gallbladder. Biliary colic: episodic RUQ or epigastric pain caused by transient obstruction of the cystic duct by a gallstone, without inflammation or infection.

Epidemiology

Gallstones present in ~10-15% of US adults; ~80% lifetime asymptomatic. Annual risk of biliary symptoms in asymptomatic patients ~1-4%/year. Female predominance, especially in childbearing years.

Question 1GastrointestinalEasy
A 42-year-old woman presents with recurrent episodes of right upper quadrant pain lasting 30-60 minutes, especially after fatty meals. Ultrasound shows multiple gallstones with acoustic shadowing. No fever, no leukocytosis. Total bilirubin is normal. What is the most appropriate management?
  • AERCP followed by cholecystectomy
  • BEmergent cholecystectomy
  • CUrsodeoxycholic acid
  • DElective laparoscopic cholecystectomy
Reveal answer & full explanation
Correct answer: D — Elective laparoscopic cholecystectomy
  • AERCP followed by cholecystectomy
  • BEmergent cholecystectomy
  • CUrsodeoxycholic acid
  • DElective laparoscopic cholecystectomy✓

Why Elective laparoscopic cholecystectomy is correct

  • This is symptomatic cholelithiasis (biliary colic): episodic right upper quadrant (RUQ) pain after fatty meals, no fever, normal labs, and gallstones on ultrasound
  • Elective laparoscopic cholecystectomy is the treatment of choice

Why the others are wrong

  • A) ERCP followed by cholecystectomy — choledocholithiasis (common bile duct stones with elevated bilirubin and alkaline phosphatase) is managed with ERCP then cholecystectomy; bilirubin is normal here
  • B) Emergent cholecystectomy — acute cholecystitis (Murphy sign, fever, leukocytosis) would warrant urgent cholecystectomy; those features are absent here
  • C) Ursodeoxycholic acid — used in primary sclerosing cholangitis (PSC) and select non-surgical candidates
Question 2GastrointestinalMedium
A 42-year-old woman has episodic right upper-quadrant pain after fatty meals. Ultrasound shows gallstones without wall thickening or duct dilation. Which of the following is the most appropriate management?
  • APercutaneous cholecystostomy tube
  • BOral ursodeoxycholic acid therapy
  • CUrgent ERCP with sphincterotomy
  • DLaparoscopic cholecystectomy
Reveal answer & full explanation
Correct answer: D — Laparoscopic cholecystectomy
  • APercutaneous cholecystostomy tube
  • BOral ursodeoxycholic acid therapy
  • CUrgent ERCP with sphincterotomy
  • DLaparoscopic cholecystectomy✓

Why Laparoscopic cholecystectomy is correct

  • Recurrent post-prandial right-upper-quadrant pain with stones and no inflammation is symptomatic cholelithiasis (biliary colic).
  • Definitive treatment of symptomatic gallstones is elective cholecystectomy, which removes both the stones and the diseased reservoir.
  • Absence of wall thickening, fever, or duct dilation confirms uncomplicated disease suited to elective surgery.

Why the others are wrong

  • Urgent ERCP with sphincterotomy — ERCP targets choledocholithiasis or cholangitis, signaled by a dilated duct or jaundice, neither of which is present; this escalates the procedure beyond the disease.
  • Oral ursodeoxycholic acid therapy — Bile-acid dissolution works only on small radiolucent stones, takes months, and relapses after stopping, so it is not the management for a surgical candidate with recurrent colic.
  • Percutaneous cholecystostomy tube — Drainage is reserved for acute cholecystitis in a critically ill or non-operative patient; this woman has uncomplicated colic with no wall thickening and tolerates definitive elective surgery.

Risk factors

  • Cholesterol stones (75% in Western countries): 4 F's — Female, Fat (obesity), Forty, Fertile (pregnancy/OCP); also rapid weight loss, total parenteral nutrition, Native American ethnicity (Pima), Crohn disease (terminal ileum — bile salt malabsorption)
  • Pigment stones (black — chronic hemolysis: sickle cell, hereditary spherocytosis, thalassemia, mechanical valve hemolysis; cirrhosis)
  • Pigment stones (brown — biliary infection/stasis: parasitic infection in Asia — Clonorchis, Ascaris; biliary stricture)
  • Medications: ceftriaxone (biliary sludge), octreotide, fibrates, estrogens
  • Diabetes, metabolic syndrome
  • Familial predisposition

Pathophysiology

Cholesterol stones: bile supersaturation with cholesterol + gallbladder hypomotility + nucleation factors. Pigment stones: increased unconjugated bilirubin (hemolysis) or biliary stasis/infection precipitates calcium bilirubinate. Biliary colic results when a stone transiently obstructs the cystic duct (during/after gallbladder contraction), causing distension and visceral pain.

Clinical presentation

Symptoms

  • Episodic, postprandial (especially after fatty meals) RUQ or epigastric pain
  • Pain builds over 15-30 min, plateaus, and resolves within 6 h (typically 1-5 h)
  • Radiation to right scapula or interscapular area
  • Nausea, vomiting, diaphoresis during episodes
  • Pain-free intervals between attacks
  • ABSENCE of fever, jaundice, or persistent pain — suggests uncomplicated biliary colic

Signs / physical exam

  • Often normal exam between episodes
  • Mild RUQ tenderness during attack, but Murphy sign typically NEGATIVE
  • No fever
  • No jaundice
  • Murphy positive + fever or persistent pain → think cholecystitis

Classic findings

Postprandial RUQ pain after fatty meal, lasting 1-5 h, recurrent over weeks to months, with gallstones on US.

Differential diagnosis

  • Acute cholecystitis — Sustained pain >6 h, fever, leukocytosis, Murphy sign, US findings of wall thickening/pericholecystic fluid
  • Choledocholithiasis — Jaundice, elevated bilirubin, dilated CBD on imaging
  • Acute pancreatitis — Epigastric pain to back, lipase >3× ULN
  • GERD / peptic ulcer — Burning epigastric pain, relieved by antacids; postprandial similar but no Murphy
  • Functional dyspepsia / sphincter of Oddi dysfunction — Recurrent pain without stones; manometry or empiric trial
  • Hepatic capsule pain (hepatitis, Fitz-Hugh-Curtis, abscess) — Elevated LFTs, specific findings
  • Cardiac (inferior MI, pericarditis) — ECG, troponin in older or atypical presentations

Diagnostic workup

Labs

  • CBC, BMP, LFTs — all typically normal in uncomplicated biliary colic
  • Lipase — exclude pancreatitis
  • Elevated bilirubin or alk phos raises concern for CBD obstruction

Imaging

  • RUQ ultrasound — first-line; sensitivity >95% for gallstones >5 mm; identifies gallbladder wall, CBD diameter, signs of cholecystitis
  • MRCP — for suspected CBD stones
  • EUS — most sensitive for small CBD stones
  • HIDA scan — assesses gallbladder ejection fraction; <35% supports symptomatic gallbladder dysmotility (functional gallbladder disorder, biliary dyskinesia)

Treatment

First-line

  • Asymptomatic cholelithiasis — observation; NO routine cholecystectomy
  • Symptomatic cholelithiasis (biliary colic) — elective laparoscopic cholecystectomy
  • Analgesia (NSAIDs preferred — also reduce risk of progression to cholecystitis)
  • Antiemetics
  • Dietary advice — low-fat diet may reduce attacks while awaiting surgery

Second-line / adjunct

  • Prophylactic cholecystectomy for asymptomatic stones in selected high-risk groups: porcelain gallbladder (cancer risk), large stones >3 cm, gallbladder polyps >1 cm, hereditary spherocytosis or sickle cell during splenectomy, transplant candidates
  • Oral bile acid dissolution (ursodeoxycholic acid) — limited efficacy, high recurrence; reserved for patients unfit for surgery
  • Extracorporeal shock wave lithotripsy — rarely used
  • ERCP with sphincterotomy and stone extraction for retained CBD stones

Complications

  • Progression to acute cholecystitis
  • Choledocholithiasis — stone in CBD
  • Ascending cholangitis
  • Gallstone pancreatitis
  • Mirizzi syndrome
  • Gallstone ileus (mechanical SBO from large stone via cholecystoenteric fistula)
  • Gallbladder cancer — porcelain gallbladder, large stones, polyps >1 cm, primary sclerosing cholangitis

PANCE pearls

  • Asymptomatic gallstones do NOT warrant cholecystectomy in most patients — annual risk of symptoms is low.
  • Indications for prophylactic cholecystectomy in asymptomatic disease: porcelain gallbladder, polyps >1 cm, stones >3 cm, sickle cell or hereditary spherocytosis (concurrent with splenectomy), transplant candidates.
  • Biliary colic resolves within 6 h — sustained pain beyond 6 h with fever/leukocytosis = acute cholecystitis.
  • RUQ ultrasound is first-line — sensitive, specific, no radiation, low cost.
  • MRCP and EUS are most sensitive for CBD stones when ultrasound is non-diagnostic.
  • Functional gallbladder disorder (biliary dyskinesia): typical biliary pain, no stones, HIDA EF <35% — cholecystectomy can help selected patients but outcomes variable.
  • Cholesterol stones predominate in Western populations; pigment stones in Asian populations and in hemolytic anemias.
  • Sickle cell patients should have cholecystectomy at time of splenectomy due to high pigment stone burden.
  • Pregnancy: cholecystectomy preferred in second trimester if symptomatic; conservative management with low-fat diet for mild attacks.
  • Ursodeoxycholic acid reduces stone formation during rapid weight loss after bariatric surgery.
