Imaging after laparoscopic cholecystectomy.

Imaging for laparoscopic cholecystectomy involves preoperative imaging of the gallbladder and bile ducts, usually by sonography. Post-operative imaging is usually necessary only for suspected surgical complications. Cross-sectional imaging identifies most patients with postoperative complications. Cholangiography is needed to characterize all biliary abnormalities. Interventional radiologic techniques are helpful to aspirate or drain abdominal fluid collections, provide temporary biliary drainage, or cure cystic stump leaks or treat complications of choledochojejunostomy.
