Endoscopic Procedures V: ERCP

49
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Summary

Laparoscopic reverse cholangiopancreatography (LRCP) significantly improves laparoscopic common bile duct exploration (LCBDE) success rates. This algorithm-driven approach enhances stone clearance and reduces the need for choledochotomy.

Area of Science:

  • Minimally Invasive Surgery
  • Gastroenterology
  • Surgical Innovation

Background:

  • Laparoscopic common bile duct exploration (LCBDE) is a safe and effective procedure.
  • The traditional transcystic approach has limitations in clearance efficacy compared to transcholedochal methods.
  • A novel algorithm-driven technique, Laparoscopic Reverse Cholangiopancreatography (LRCP), has been developed to improve LCBDE outcomes.

Purpose of the Study:

  • To report the evolution of LCBDE techniques.
  • To introduce and evaluate an algorithm-driven approach (LRCP) for prioritizing antegrade clearance.
  • To compare the efficacy of LRCP with the "classic" transcystic LCBDE technique.

Main Methods:

  • An algorithm-driven LRCP technique was developed, tailoring interventions based on patient anatomy and intraoperative cholangiogram findings.
  • Interventions included choledochoscope-assisted or fluoroscopy-guided techniques, wire basketing, "snow-plow" maneuver, sphincteroplasty, laser, or electrohydraulic lithotripsy.
  • Fallback options included ERCP or transcholedochal exploration.

Main Results:

  • A retrospective review of 80 LCBDE cases (50 "classic" phase, 30 LRCP phase) was conducted.
  • LRCP achieved a significantly higher transcystic clearance rate (97%) compared to the "classic" phase (56%) (P<0.001).
  • Zero utilization of choledochotomy was observed during the LRCP phase.

Conclusions:

  • Algorithm-driven LRCP significantly enhances transcystic clearance success in LCBDE.
  • LRCP reduces the reliance on choledochotomy, a more invasive procedure.
  • The LRCP algorithm serves as a valuable decision-making tool for surgeons performing LCBDE.
