Painless Jaundice With a Nondiagnostic Biopsy: Deciding on a Whipple
A 67-year-old woman presents with 6 weeks of painless jaundice, pruritus and 7 kg weight loss. She has diet-controlled type 2 diabetes and an ECOG performance status of 0. Bilirubin is 16.2 mg/dL, alkaline phosphatase 640 U/L, albumin 33 g/L and CA19-9 512 U/mL. Contrast CT shows a 3.1 cm hypodense mass in the pancreatic head with a double-duct sign; there is no contact with the superior mesenteric artery or vein, no venous distortion, and no liver or peritoneal deposits. Endoscopic ultrasound confirms a solid mass, but fine-needle aspiration is reported as 'atypical cells, suspicious but not diagnostic'. Bilirubin has risen from 9 to 16 mg/dL in 10 days and she has had one rigour with a temperature of 38.3 °C.
1. Should this patient's jaundice be drained before surgery? Give your reasoning and specify the route and timing.
Read the worked answer
Preoperative biliary drainage is not routine - it increases stent-related cholangitis, pancreatitis, and surgical site infection - but this patient has specific indications: a documented febrile rigour suggesting cholangitis, intractable pruritus, a rising bilirubin and, importantly, a liver that will need time to recover before a Whipple.
Route: endoscopic retrograde cholangiopancreatography with a short covered self-expandable metal stent is preferred when the diagnosis is established and surgery is expected within a few weeks; a plastic stent is used if surgery will be delayed beyond about 3 months or the diagnosis is uncertain, but plastic stents occlude and need exchange. Percutaneous drainage is reserved for failed ERCP or hilar obstruction.
Timing: drain, treat the infection with antibiotics, then allow 4–6 weeks for bilirubin and synthetic function to improve before resection. Draining does not make the operation urgent by itself, but a stent that becomes infected or blocked does, so the interval should be short and deliberate, with the Whipple booked rather than left open-ended. Rehearse the plan with the patient: stent today, surgery in several weeks, and a plan for what happens if cholangitis recurs.
2. How do you assess resectability and stage this tumour further, and what do you do about the nondiagnostic FNA?
Read the worked answer
Resectability is a radiological judgement about arterial and venous contact. This CT describes a pancreatic head mass with no SMA or SMV contact and no venous distortion, so it is anatomically resectable; there is no distant disease described. There should be no celiac or hepatic artery encasement, and no SMV/PV occlusion or thrombosis beyond a reconstructable segment. Serum CA19-9 of 512 U/mL with a 3 cm mass raises the probability of occult peritoneal or liver disease, so staging laparoscopy is reasonable, with a yield of roughly 10–20% in this risk group.
The nondiagnostic FNA is a real problem: a Whipple for benign disease carries substantial morbidity. The options are to repeat EUS-FNA with a larger needle and rapid on-site cytology, or to proceed with intraoperative frozen section of the pancreatic head and a suspicious node before committing to resection. Non-malignant mimics must be considered - autoimmune pancreatitis (check IgG4, review imaging for a capsule-like rim and diffuse enlargement) and lymphoma. The case should go to a multidisciplinary meeting: if cytology remains indeterminate but the radiology is typical and the patient is fit, resection with frozen section is defensible; if frozen section shows benign disease, stop and close.
3. On day 6 after a pancreaticoduodenectomy, the drain puts out 350 mL/day with an amylase of 4200 U/L. She is febrile at 38.5 °C with a white cell count of 18 × 10⁹/L, and CT shows no collection. Outline your management.

This is a clinically significant pancreatic fistula - drain amylase far above three times the serum value with a change in management and suspected infection. By the ISGPS grading it is at least grade B. The absence of organ failure and of a collection keeps it out of grade C for now, but the fever and leucocytosis mean it can escalate.
Management:
- Leave the drain in place and do not remove it; the drain is the treatment.
- Send drain fluid for culture, start antibiotics covering enteric organisms, and obtain blood cultures.
- Keep the patient nil by mouth if she is vomiting or ileus is present, otherwise use jejunal or enteral nutrition where possible and parenteral nutrition if not.
- Reassess with repeat cross-sectional imaging, and look specifically for a pseudoaneurysm or sentinel bleed; a small bleed can precede a catastrophic arterial erosion, and CT angiography with angioembolisation is the response.
- Octreotide is not routinely indicated; it does not reliably close fistulae and its role is adjunctive.
- If a collection develops, drain it percutaneously; avoid aggressive early surgical exploration.
- Escalate to relaparotomy only for uncontrolled sepsis, bleeding or a disconnected pancreatic remnant.
