<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 41-year-old G3P3 woman presents with acute on chronic right upper quadrant abdominal pain. She says that her current symptoms acutely onset 8 hours ago after eating a large meal and have not improved. She describes the pain as severe, sharp and cramping in character, and localized to the right upper quadrant. She also describes feeling nauseous. The patient says she has had similar less severe episodes intermittently for the past 2 years, usually precipitated by the intake of fatty foods. She denies any history of fever or jaundice. Vital signs are stable. Physical examination is unremarkable, and laboratory findings show normal liver function tests and normal serum bilirubin and serum amylase levels. Ultrasonography of the abdomen reveals multiple stones in the gallbladder. The patient is managed symptomatically for this episode, and after a few months, undergoes elective cholecystectomy, which reveals multiple stones in her gallbladder as shown in the figure see image. Which of the following best describes these gallstones?? A: They are formed due to elevated uric acid in the blood., B: They are formed due to the release of beta-glucuronidase from infecting bacteria., C: These are usually radiopaque on X-ray imaging., D: They are formed due to bile supersaturated with cholesterol., E: These are seen in patients with chronic hemolysis.,  <response>: This is a clinical vignette describing a patient with typical symptoms of biliary colic and imaging findings consistent with cholelithiasis gallstones. The question stem provides key details about the acute onset of right upper quadrant pain after a large, fatty meal in a patient with a history of similar episodes, along with normal lab tests and ultrasound confirmation of gallstones. The image shows multiple faceted gallstones filling the gallbladder lumen. Based on the clinical presentation and imaging, this is a straightforward case of cholesterol gallstones.Choice A can be eliminated, as uric acid stones do not form in the gallbladder. Choice B discusses beta-glucuronidase from bacteria, which can play a role in pigment gallstone formation, but is not relevant here. Choice C states the stones are radiopaque, but the vignette does not provide X-ray findings. Cholesterol stones are typically radiolucent.Choice D correctly identifies these gallstones as being formed from bile supersaturated with cholesterol, consistent with the typical presentation and ultrasound findings. Choice E brings up chronic hemolysis leading to bilirubin gallstones, which does not fit this clinical scenario.D: They are formed due to bile supersaturated with cholesterol.
