The modern era of common bile duct (CBD) surgery started with Mirizzi, who introduced intraoperative cholangiography in 1932. Intraoperative choledoscopy had been developed as an adjunctive to intraoperative cholangiography, which helped to detect CBD stones in an additional 10% to 15% of instances that otherwise would have been missed. Findings have shown choledochoscopy to be an important technique for efficient and effective management of CBD stones.

Early detection of complications after laparoscopic Roux-en-Y gastric bypass (LRYGB) can be difficult because of the subtle clinical findings in obese patients.

The medical records of 368 consecutive patients undergoing LRYGB were analyzed to determine the efficacy of selective use of radiological studies after LRYGB.
