Roux-en-Y Hepaticojejunostomy: Technique and Indications
Roux-en-Y hepaticojejunostomy is the definitive surgical reconstruction for major bile duct injuries (Strasberg E1-E5) involving complete loss of common and/or hepatic bile duct continuity, and should be performed by experienced hepatopancreatobiliary (HPB) surgeons in tertiary care centers. 1
Primary Indications
The procedure is indicated for:
- Major bile duct injuries (Strasberg E1-E5) with complete ductal transection or loss of continuity 1
- Late-recognized bile duct injuries presenting with stricture formation after cholecystectomy 1
- Benign biliary strictures refractory to endoscopic management 1
- Choledochal cysts requiring biliary-enteric reconstruction 2
- Recurrent hepatolithiasis with biliary strictures 3
- Extrahepatic biliary tree injuries (AAST grades IV-V) in trauma settings 4
Timing of Surgical Repair
The timing critically impacts outcomes:
Immediate Repair (Within 72 hours)
For major BDIs diagnosed within 72 hours postoperatively, urgent referral to an HPB center for immediate Roux-en-Y hepaticojejunostomy is recommended if local expertise exists. 1 Early aggressive repair (within 48 hours) avoids sepsis development, reduces costs, and improves hospital readmission rates. 1
Delayed Repair (72 hours to 3 weeks)
Between 72 hours and 3 weeks, the proliferative healing phase complicates surgical repair. During this period:
- Perform percutaneous drainage of fluid collections
- Administer targeted antibiotics and nutritional support
- Consider ERCP with sphincterotomy ± stent to reduce biliary pressure
- Use PTBD for septic patients with complete CBD obstruction
- After minimum 3 weeks, once acute inflammation resolves, perform Roux-en-Y hepaticojejunostomy 1
Late Recognition
When major BDIs present with stricture manifestations months to years after initial surgery, Roux-en-Y hepaticojejunostomy should be performed. 1
Critical Technical Principles
The fundamental requirement is a tension-free bilioenteric anastomosis with excellent mucosal apposition and well-vascularized ducts. 1
Key Technical Steps:
Hilar Exposure: Lower the right-sided hilar plate carefully. Avoid excessive hilar dissection, which risks further biliary or vascular injury and complicates subsequent reconstruction. 1
Bile Duct Preparation:
Roux Limb Creation:
- Fashion a 40-60 cm antecolic or retrocolic Roux limb from jejunum
- Create jejunojejunostomy using side-to-side double staple technique
- Close common enterotomy in running watertight fashion 6
Hepaticojejunostomy Construction:
- Position Roux limb to porta hepatis without tension
- Create side-to-side or end-to-side anastomosis using 4-0 or 5-0 absorbable sutures 7, 2
- For robotic/laparoscopic approach: Place index suture at 9 o'clock, run posterior wall to 3 o'clock, then complete anterior wall from both corners meeting at 12 o'clock 6
- Ensure wide anastomosis (>1 cm diameter when possible) to minimize stricture risk 5
Stenting Considerations:
Surgical Approach Options
Open Surgery
Traditional approach, particularly when:
- Extensive adhesions from prior surgery
- Associated vascular injuries requiring repair
- Surgeon lacks advanced minimally invasive skills
Minimally Invasive (Laparoscopic/Robotic)
Increasingly utilized with advantages including:
- Enhanced visualization and magnification
- Improved tissue handling precision
- Better cosmesis and recovery 6, 8
- Requires significant HPB expertise for safe execution 8, 9
Robotic approach particularly beneficial for:
- High bile duct injuries above hilar plate 8
- Complex biliary reconstructions requiring precise suturing 6, 5
- Repeat operations with dense adhesions 3
Critical Pitfalls to Avoid
Non-expert immediate repair attempts are associated with significantly worse outcomes than expert repair, potentially compromising later revisions. 1 Specifically:
- Do NOT attempt repair without HPB expertise - failure rates approach 60% vs. 34% for expert delayed repair 1
- Avoid end-to-end anastomosis when possible - associated with increased failure rates compared to hepaticojejunostomy 1
- Do NOT perform excessive hilar dissection during injury assessment - risks further damage 1
- Avoid conversion to open solely for diagnosis - place drain and transfer to HPB center instead 1
Expected Outcomes
Short-term Results:
- Overall success rate: 83% in early period 1
- Operative mortality: 1.8-4.6% 1
- Common complications: anastomotic leak (variable), bleeding, cholangitis 3
Long-term Complications:
- Anastomotic stricture: 10-20% (range 4-69% across studies), typically occurring 11-30 months postoperatively 1
- Recurrent cholangitis: 32-39% of patients 1, 2
- Biliary cirrhosis: 2.4-10.9% 1
- Risk factors for stricture: associated vascular injury, level of BDI, sepsis/peritonitis, postoperative bile leak 1, 2
Postoperative bile leak and early cholangitis are strong predictors of subsequent anastomotic stricture formation (p=0.021 and p<0.001 respectively). 2
Special Circumstances
Diffuse Biliary Peritonitis
When major BDIs present with diffuse peritonitis, urgent abdominal lavage and drainage for source control must precede definitive reconstruction. 1
Associated Vascular Injury
Intraoperative ultrasound should evaluate for vascular injuries. Associated vascular damage significantly worsens prognosis and increases stricture risk. 1
Damage Control Scenarios
In trauma or unstable patients, initial drainage with staged reconstruction is appropriate. 4
