We report a 53-year-old woman with obstructive jaundice and severe hepatobiliary injury. Ultrasonography and contrast-enhanced computed tomography showed a giant extrahepatic bile duct cyst measuring ~15\u201316\u00a0cm, marked intrahepatic duct dilatation, gallbladder distension, and enhancing biliary walls without a visible obstructing stone, consistent with a Todani type IVa choledochal cyst complicated by cholangitis. Ultrasound-guided percutaneous biliary drainage was performed, with marked biochemical improvement. Definitive open surgery included cholecystectomy, complete extrahepatic cyst excision, and Roux-en-Y hepaticojejunostomy. This case highlights a surgical pitfall in which a giant bile duct cyst mimics gallbladder hydrops and supports staged decompression before definitive biliary reconstruction when cholangitis is present.<\/jats:p>","DOI":"10.1093\/jscr\/rjag833","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T11:12:28Z","timestamp":1788520348000},"source":"Crossref","is-referenced-by-count":0,"title":["Staged
