October 2009 Article in the Examiner describing what can go wrong during a routine infant circumcision. No organization tracks circumcision complications, so very little information is available.

Complications range in severity from the "mild:" excessive bleeding, infection (including antibiotic resistant Staphylococcus), to the severe: surgically caused genital deformity, accidental amputation, and even death. And complication rates are higher in children circumcised shortly after birth than in older children (and presumably adults also), possibly because surgery on such a small child is more intricate.

The article even continues to describe how there is burgeoning industry for repairing damage from circumcision.
