Final answer:
A patient with cholecystitis and jaundice from cholelithiasis likely experiences pruritus, as it is common when bile salts build up in the bloodstream and cause itching. Cullen's sign and Grey Turner's sign are not related to cholecystitis, and polyphagia is typically indicative of diabetes, not biliary obstruction.
Step-by-step explanation:
A patient with cholecystitis caused by cholelithiasis (gallstones) that leads to an obstruction can experience several symptoms, including jaundice, which is indicated by yellowing of the skin and eyes. This obstruction in the bile ducts results in an increase in conjugated bilirubin in the blood, often leading to the skin condition called jaundice. Among the possible symptoms a patient might experience due to this condition, pruritus (itchiness) is a common one. The buildup of bile salts in the bloodstream can lead to itching of the skin.
Other symptoms, such as Cullen's sign and Grey Turner's sign, are associated with acute pancreatitis and retroperitoneal hemorrhage, respectively, and are not typically related to cholecystitis. Polyphagia, or excessive hunger, is usually associated with conditions like diabetes, but not cholecystitis. Therefore, pruritis is most consistent with the symptoms described for a patient suffering from jaundice due to biliary tree obstruction.
