Patient description: A 54-year-old obese woman admitted to the emergency department with abdominal pain that started 4 days ago with nausea and vomiting. The epigastric pain radiates to the right upper quadrant, getting worse after eating fatty food. The patient experienced similar pain twice in the past year. Her past medical history is remarkable for hypercholesterolemia and 2 NVDs. She has 2 children, and she is menopausal. She does not smoke, drink alcohol, or use illicit drugs. She is mildly febrile. Her BP is 150/85, HR 115, RR 15, T 38.2, SpO2 98% on RA. She is an obese woman with no acute distress. On palpation, she experiences epigastric tenderness and tenderness in the right upper quadrant without rebound. Bowel sounds are normal. Laboratory analysis is remarkable for elevated ESR and leukocytosis with a left shift. The ultrasound revealed several gallstones, biliary sludge and CBD stones. The smallest stone is 14mm.
