Candor: the team deserves to know. If this is benign, they will know or have the chance to discuss amongst themselves. If it's not benign, it's better to kick this hornet's nest early to give them time to react and decide, increasing their autonomy. I reject the option of staying silent. I haven't got enough information to know this is safe, beyond a lazy appeal to authority of an entity that may be compromised or possessed of a blind spot that doesn't see or refuses to acknowledge weakness in the relevant area. I reject the option of notifying only the surgeon. The whole team is working on the patient as a unit. Notifying only one member and keeping others in the dark reeks of facilitating face-saving in a setting that doesn't warrant it - not only would that be the wrong decision, but I actively and authentically despise the concept of harm being caused to another just because someone's ego could bleed a little.
