Obstructive Jaundice Complicated by Cholangitis: Timing the Whipple
Mr K is 63 with three weeks of painless jaundice and 6 kg of weight loss. Bilirubin is 265 µmol/L, ALP 480 U/L, CA19-9 620 U/mL, haemoglobin 10.8 g/dL. CT shows a 2.9 cm hypodense mass in the pancreatic head; there is no contact with the superior mesenteric artery or coeliac axis, the superior mesenteric vein is clear, and there are no liver metastases or ascites. He now returns with rigors, a temperature of 39.2 °C, blood pressure 88/50 mmHg and confusion; lactate is 3.4 mmol/L. He is a non-smoker, walks daily, and has no cardiac history.
1. Outline your management for the next 24 hours, including the choice of biliary drainage and the type of stent you would use.

Diagnosis and priority Acute cholangitis with organ dysfunction (grade III) complicating malignant distal biliary obstruction. This is a septic emergency: the obstruction must be relieved, but not by pancreaticoduodenectomy today.
First six hours
- Sepsis bundle: blood cultures, broad-spectrum antibiotics with biliary penetration (piperacillin-tazobactam, or a third-generation cephalosporin with metronidazole), fluid resuscitation with balanced crystalloid, early vasopressors if the mean arterial pressure remains below 65 mmHg, and ICU admission.
- Correct calcium and glucose, check coagulation, give vitamin K for the jaundice-related deficiency.
- Urgent biliary drainage - within 12–24 hours in grade III disease, and once resuscitation is under way.
Drainage route and stent choice
- ERCP with sphincterotomy and stenting is first line. If ERCP fails, percutaneous transhepatic drainage.
- Use a short plastic stent (7–10 Fr), not a self-expanding metal stent, because he is a surgical candidate. Metal stents provoke tissue hyperplasia, are harder to remove, and increase the technical difficulty and infective complications of a subsequent pancreaticoduodenectomy.
- Metal stents are reserved for patients being palliated or receiving neoadjuvant therapy over many months.
What not to do Do not take him for resection while he is septic and vasopressor-dependent; mortality is prohibitive.
2. Once he has recovered, how do you assess resectability, is EUS-guided fine-needle aspiration needed, and when would you give neoadjuvant therapy first?

Resectability assessment
- Confirm absence of distant disease: contrast CT of chest, abdomen and pelvis; consider FDG-PET if there is doubt, and staging laparoscopy if CA19-9 is very high or the primary is large, to detect small peritoneal deposits.
- Vessel-by-vessel review on a dedicated pancreatic protocol CT: tumour contact with the superior mesenteric artery, coeliac axis or hepatic artery of 180° or more, or any contact with the superior mesenteric vein/portal vein with thrombosis or occlusion, defines unresectability. Less than 180° contact without thrombosis is borderline. This lesion appears resectable.
Is tissue needed? If he goes straight to surgery, a preoperative histological diagnosis is not mandatory, and EUS-FNA carries a small risk of needle-tract seeding and of pancreatitis. It becomes necessary if neoadjuvant chemotherapy is planned, if the diagnosis is in doubt (autoimmune pancreatitis, lymphoma), or if the patient is unfit for surgery and palliation is being planned.
When to give neoadjuvant treatment Borderline vascular contact, a very high CA19-9 with a large node burden, or a patient who needs to prove biological stability. Otherwise, upfront resection is standard.
Preoperative optimisation Bilirubin falling, cholangitis fully resolved for at least four weeks, vitamin K and nutrition corrected, and carbohydrate loading - operating on a recently septic, jaundiced patient increases pancreatic fistula and infective complications.
3. Six weeks later, after recovery and stent exchange, he asks why he cannot be operated on next week. What determines the interval, and what would make you abandon resection intraoperatively?
Read the worked answer
Why wait The interval is not bureaucratic. After grade III cholangitis he needs:
- Resolution of the systemic inflammatory response - operating during a catabolic, septic phase produces more pancreatic fistulae, more wound infections and higher mortality.
- Recovery of nutrition and functional reserve; six weeks of a high-protein diet and physiotherapy can convert a borderline-fit patient into a fit one.
- Time for the bilirubin to fall and the liver to recover synthetic function, and for coagulopathy to be corrected with vitamin K.
- Time to complete staging, including a repeat cross-sectional study - about 10–20% of patients develop interval metastases, and a repeat scan avoids a futile operation.
Intraoperative abandonment - the judgement call
- Peritoneal deposits or liver metastases confirmed on frozen section.
- Tumour infiltration of the superior mesenteric artery or the root of the mesentery, or of the portal vein/SMV that cannot be reconstructed safely.
- A positive margin is likely: it is better to stop than to perform a Whipple with a macroscopic residual, which adds morbidity with no survival benefit.
- Haemodynamic instability or an unexpected cirrhotic liver.
If unresectable, proceed to double bypass (hepaticojejunostomy and gastrojejunostomy) and refer for palliative chemotherapy, rather than leaving him with a blocked stent and gastric outlet obstruction.
