A 60-year-old patient presents with painless jaundice. ERCP shows a stricture at the lower end of the common bile duct with pancreatic duct dilation (double duct sign). CA 19-9 is 3200 U/mL. CT shows a 3 cm pancreatic head mass without vascular involvement. What is the most appropriate initial management?
- A Biliary stenting followed by neoadjuvant chemotherapy before surgery
- B EUS-guided FNA followed by chemotherapy
- C Direct surgical resection (Whipple's procedure) without preoperative biliary drainage if bilirubin < 250 μmol/L ✓
- D Palliative bypass surgery as CA 19-9 > 1000 indicates unresectability
Explanation
For resectable pancreatic head cancer with bilirubin below 250 μmol/L, direct surgical resection (Whipple's pancreaticoduodenectomy) without preoperative biliary drainage is preferred, as the DRAINAGE trial showed that routine preoperative biliary drainage increases infectious complications without improving surgical outcomes. Biliary drainage is reserved for very high bilirubin (>250 μmol/L), cholangitis, or delays before surgery. Tissue confirmation is not routinely required before resection when imaging strongly suggests resectable pancreatic adenocarcinoma. CA 19-9 level alone does not indicate unresectability.
