A patient with pancreatic head cancer presenting with signs of bile duct obstruction would most likely exhibit which symptom?

• A. Dark tea colored urine
• B. Clay-colored stools
• C. Jaundice
• D. Lower abdominal pain

Answer: (C)

When bile flow is blocked by a pancreatic head tumor, bilirubin cannot reach the gut and backs up into the bloodstream, causing obstructive jaundice. The buildup of conjugated bilirubin in the blood leads to yellowing of the skin and eyes, which is the most noticeable and typical symptom in this scenario. Other signs like dark tea-colored urine and clay-colored stools reflect the same blockage—conjugated bilirubin appears in the urine, while the lack of bile pigments reaching the intestine makes stools pale—but jaundice is the hallmark, visible clue that people notice first. Lower abdominal pain isn’t as characteristic of this biliary obstruction pattern, which reinforces jaundice as the best fit.
