What is the management approach for a patient with extrahepatic biliary obstructive jaundice (EHBOJ) based on a famous study from a specific location?

Management of Extrahepatic Biliary Obstructive Jaundice: The Netherlands Study

Routine preoperative biliary drainage should be avoided in patients with extrahepatic biliary obstructive jaundice (EHBOJ) who are surgical candidates, based on the landmark Dutch randomized controlled trial that demonstrated a significant increase in serious complications (74% vs. 39%) despite technically successful drainage in 94% of cases. 1

The Netherlands Study: Key Findings

The high-quality randomized trial from the Netherlands compared preoperative drainage to early surgery (within 1 week) for patients with malignant distal biliary obstruction, including distal cholangiocarcinoma, pancreatic head cancers, and ampullary tumors. 1 This study fundamentally challenged the previously held belief that relief of preoperative jaundice improved perioperative outcomes. 1

Infectious complications emerged as the primary driver of risk associated with drainage procedures, while the beneficial effects of drainage proved difficult to ascertain. 1

When to Deviate from the Netherlands Study Protocol

Despite the strong evidence against routine drainage, specific clinical scenarios warrant preoperative biliary decompression: 1

Absolute Indications for Preoperative Drainage:

• Acute cholangitis - requires immediate biliary decompression 1
• Renal failure - necessitates correction before major surgery 1
• Intractable pruritus - when quality of life is severely compromised 1

Relative Indications:

• High bilirubin values (>200 μmol/L) in patients requiring major hepatectomy (>60% of total liver volume) 1
• Neoadjuvant chemotherapy planned - requires bilirubin reduction to levels compatible with chemotherapy administration 1
• Planned extensive surgery - particularly major hepatectomy 1
• Expected long waiting time for surgery - when delay exceeds several weeks 1
• Portal vein embolization required - only possible after adequate biliary drainage 1

Drainage Method Selection Based on Tumor Location

For Distal Cholangiocarcinoma (dCCA):

Endoscopic drainage should be strongly preferred over percutaneous drainage due to lower complication rates and the ability to combine diagnostic sampling with therapeutic intervention. 1 The endoscopic approach offers EUS-guided fine needle aspiration/biopsy and endobiliary sample acquisition during ERCP. 1

Self-expanding metal stents (SEMSs) are superior to plastic stents for preoperative drainage, with lower 30-day occlusion rates, reduced long-term occlusion rates, fewer complications, and decreased need for re-interventions. 1

For Perihilar Cholangiocarcinoma (pCCA):

The evidence is less definitive for perihilar tumors. 1 Endoscopic drainage cannot be definitively recommended over percutaneous drainage due to insufficient evidence. 1

• Bismuth types I and II: Endoscopic transpapillary drainage may be preferred 1
• Bismuth types III and IV: Percutaneous or combined endoscopic/percutaneous drainage may be preferred 1
• Uncovered self-expanding metal stents preferred over plastic stents when drainage is performed 1

When ERCP Fails:

EUS-guided biliary drainage (EUS-BD) should be preferred over percutaneous transhepatic biliary drainage (PTBD) when adequate expertise is available. 1 Trials demonstrate that EUS-BD achieves better clinical success rates, lower adverse event rates, and lower rates of re-intervention compared to PTBD. 1

Critical Pitfalls to Avoid

The most common error is performing routine drainage based on outdated beliefs about hyperbilirubinemia correction. 1 The Netherlands study and subsequent Cochrane review of six trials with 520 patients consistently demonstrated that drainage increases complications without clear benefit in most surgical candidates. 1

Seeding metastasis risk is higher with PTBD compared to endoscopic biliary drainage for both distal cholangiocarcinoma and pancreatic cancer presenting with biliary obstruction. 1

In patients with existing cholangitis, the risk-benefit calculation changes entirely - these patients require immediate drainage regardless of the Netherlands study findings. 1

Special Consideration: Perihilar Tumors Requiring Major Hepatectomy

The minority (5-10%) of patients with perihilar cholangiocarcinoma eligible for left hemihepatectomy may safely undergo resection without prior biliary drainage. 1 However, patients requiring major hepatectomy with portal vein embolization for adequate future liver remnant must undergo biliary drainage first, as portal vein embolization is only possible after adequate biliary decompression. 1

Multidisciplinary Discussion Required

All drainage decisions should be discussed with the surgeon before proceeding, particularly regarding waiting time for surgery, extent of planned resection, and need for portal vein embolization. 1 The waiting time for surgery significantly impacts whether the shorter patency of plastic stents versus the higher cost of metal stents becomes clinically relevant. 1
