ERCP Management Concepts
What the Examiner Expects
Although ERCP is performed by gastroenterologists, the examiner expects surgeons to understand indications, complications, and management of failures. ERCP with sphincterotomy and stone extraction is the standard treatment for choledocholithiasis. For acute cholangitis (Charcot's triad: fever, jaundice, RUQ pain; Reynolds' pentad adds hypotension and altered mental status), urgent biliary decompression via ERCP is the first-line intervention. The surgeon must know when to call for ERCP (CBD stones, cholangitis, postoperative bile leaks) and how to manage ERCP complications (pancreatitis, perforation, bleeding) or ERCP failures (proceed to percutaneous transhepatic cholangiography or surgical exploration).
Key Examiner Focus Points
- Therapeutic: sphincterotomy, stone extraction, stent placement for strictures
- Indicated for choledocholithiasis, cholangitis, biliary stricture evaluation
- Post-ERCP pancreatitis is the most common complication (5–10%)
- Cholangitis management: antibiotics + urgent biliary decompression (ERCP preferred)
- Rectal indomethacin and pancreatic duct stent reduce post-ERCP pancreatitis risk
Common Curveballs
ERCP fails to cannulate the ampulla due to a periampullary diverticulum
Options: repeat ERCP with an experienced advanced endoscopist, percutaneous transhepatic cholangiography (PTC) with antegrade stone clearance or rendezvous technique, or surgical common bile duct exploration with choledochotomy.
Patient develops severe epigastric pain and a lipase of 5,000 six hours after ERCP
Post-ERCP pancreatitis. Aggressive IV fluid resuscitation, pain management, NPO. Most cases are mild and self-limited. Severity stratification with CT if worsening. Prevention for future ERCPs: rectal indomethacin and prophylactic pancreatic duct stent.
