Match each clinical scenario involving the biliary tract with the most appropriate surgical or endoscopic intervention.

  • A patient develops high-volume bilious output from a surgical drain on postoperative day 3 following an uncomplicated elective laparoscopic cholecystectomy. Imaging shows no retained common bile duct stones.Endoscopic sphincterotomy and biliary stent placement
  • During a difficult cholecystectomy for severe gangrenous cholecystitis, the common bile duct is inadvertently completely transected, resulting in a 2.5-centimeter gap between the proximal and distal duct ends.Roux-en-Y hepaticojejunostomy
  • A patient with recurrent cholangitis is found to have a 1.5-centimeter impacted common bile duct stone. Endoscopic retrograde cholangiopancreatography (ERCP) is performed, but the stone cannot be captured or fragmented.Laparoscopic common bile duct exploration and stone extraction
  • An abdominal ultrasound performed for vague epigastric discomfort incidentally reveals a 2.2-centimeter sessile, non-mobile polypoid mass projecting into the gallbladder lumen.Extended cholecystectomy with partial hepatic resection and regional lymphadenectomy

Cevap

The correct matching aligns a minor postoperative leak with ERCP, a major biliary transection with Roux-en-Y hepaticojejunostomy, a refractory CBD stone with surgical common bile duct exploration, and a large, suspicious gallbladder polyp with extended cholecystectomy.
Each scenario requires a specific stepwise intervention based on standard surgical protocols: ERCP for minor leaks, Roux-en-Y for large anatomic defects, surgical exploration for endoscopically unretrievable stones, and oncologic resection for suspected gallbladder malignancy.

Adım Adım Çözüm

1
Evaluate the postoperative bile leak scenario.
Identified as a likely cystic duct stump leak that requires ERCP.
ERCP with stenting reduces biliary tree pressure, preferentially diverting bile flow away from the leak site and allowing it to heal without major surgery.
2
Analyze the major ductal injury scenario.
Identified a 2.5-cm common bile duct gap requiring Roux-en-Y hepaticojejunostomy.
Primary repair of a large ductal gap is contraindicated due to ischemia and stricture risk; biliary-enteric drainage is mandatory for definitive reconstruction.
3
Assess the refractory choledocholithiasis scenario.
Identified failure of ERCP necessitating laparoscopic common bile duct exploration.
Surgical common bile duct exploration is the standard fallback when advanced endoscopic techniques fail to clear a large, impacted stone.
4
Evaluate the large gallbladder polyp scenario.
Identified a 2.2-cm polyp highly suspicious for malignancy requiring extended cholecystectomy.
To provide an adequate oncologic resection, extended cholecystectomy including the gallbladder bed and regional lymph nodes is required for polyps >2 cm.
