In a patient with persistent abdominal tenderness after laparoscopic cholecystectomy who does not have jaundice, what is the most likely diagnosis and recommended workup and management?

Post-Cholecystectomy Persistent Abdominal Tenderness Without Jaundice

In a patient with persistent abdominal tenderness after laparoscopic cholecystectomy without jaundice, the most likely diagnosis is a minor bile duct injury (Strasberg A-D) presenting as a bile leak, and you should immediately obtain liver function tests followed by abdominal CT as first-line imaging. 1

Most Likely Diagnosis

The absence of jaundice is a critical distinguishing feature that points toward:

• Minor bile duct injury (BDI) - particularly cystic duct stump leak or duct of Luschka injury (Strasberg A-D classification)
• Bile leak with collection/biloma rather than major ductal transection
• Retained cystic duct remnant with calculi (less common but increasingly recognized) 2, 3

Jaundice typically indicates major BDI with complete ductal obstruction (Strasberg E1-E5), which is NOT your scenario. Without jaundice, you're dealing with a leak rather than obstruction.

Immediate Workup Algorithm

Step 1: Laboratory Assessment

Obtain liver function tests immediately, including: 1

• Direct and indirect bilirubin
• AST, ALT, ALP, GGT
• Albumin
• If patient appears systemically ill: add CRP, procalcitonin, lactate

Key point: Normal or mildly elevated transaminases with minimal bilirubin elevation supports bile leak rather than obstruction.

Step 2: First-Line Imaging

Abdominal triphasic CT is the recommended first-line imaging to detect: 1

• Intra-abdominal fluid collections (bilomas)
• Ductal dilation (absence suggests leak rather than obstruction)
• Free fluid/peritonitis

Step 3: Definitive Biliary Imaging

Add contrast-enhanced MRCP (CE-MRCP) for: 1

• Exact visualization and localization of bile leak
• Classification of BDI type
• Essential for treatment planning
• Superior to conventional MRCP with sensitivity 76-82% vs 53-63%

Critical timing note: The absence of jaundice and ductal dilation makes MRCP technically more challenging but still essential for leak localization.

Management Strategy

For Minor BDI (Most Likely in Your Case)

If surgical drain is in place and shows bile: 1

• Initial observation with non-operative management is appropriate
• Monitor drain output and clinical status

If no drain was placed: 1

• Percutaneous drainage of any collection is the first intervention
• This may be definitive treatment for cystic duct or Luschka duct leaks

If no improvement or worsening after percutaneous drainage: 1

• ERCP with biliary sphincterotomy and stent placement becomes mandatory (Grade 1C recommendation)
• Success rate 87-100% for minor leaks 1
• Stents remain 4-8 weeks

Red Flags Requiring Different Approach

Watch for signs suggesting major BDI despite lack of jaundice:

• Diffuse peritonitis → requires urgent laparotomy for source control 1
• Sepsis/hemodynamic instability → broad-spectrum antibiotics within 1 hour (piperacillin/tazobactam, imipenem, or meropenem) 1
• Complete lack of bile duct continuity on MRCP → requires HPB surgical referral for hepaticojejunostomy 1

Common Pitfalls to Avoid

1. Don't assume functional dyspepsia - Persistent symptoms after cholecystectomy warrant structural investigation, especially when pain is the predominant feature 3, 4

2. Don't delay imaging - The 2020 WSES guidelines emphasize prompt investigation of patients who don't rapidly recover, with abdominal pain being a key alarm symptom 1

3. Don't perform ERCP as first diagnostic test - CT first to identify collections, then MRCP for ductal anatomy, then ERCP as therapeutic intervention 1, 5

4. Don't miss retained cystic duct remnant - Increasingly recognized cause of post-cholecystectomy pain; ultrasound may identify calculi in remnant stump 6, 2, 3

Alternative Diagnoses to Consider

While less likely given persistent tenderness:

• Cystic duct stump calculus - presents with postprandial pain, may have mildly elevated ALT, requires targeted ultrasound 2, 3
• Post-cholecystectomy syndrome - but this typically presents with flatulence (17.8%), frequent bowel movements (9.6%), and diarrhea (8.4%) rather than persistent tenderness 4

The structured approach: Labs → CT → MRCP → Percutaneous drainage if collection present → ERCP if no improvement, maximizes diagnostic accuracy while minimizing invasive procedures.
