IOC has the potential to benefit the surgeon in the following two ways:

  • Prevention of CBD injury - Although IOC may help prevent such injuries, [47, 48] the literature does not support using it on a routine basis; this modality is most likely to yield benefit if used selectively in cases of unclear anatomy [49]
  • Identification of choledocholithiasis - Even if IOC is performed only selectively, many cholangiograms would have to be obtained to find a small number of stones; thus, IOC is not cost-effective for this purpose [50, 51]

In randomized trials, formal residency training, like routine use of IOC, has not been shown to reduce the number of bile duct injuries.
