Condoleezza Rice paraphrased a Ronald Reagan aphorism changing it to "Distrust & Verify". If the surgeon is trained in the Retzius technique she or he can state it in writing with the when, the where, the who (trainer), and how many Retzius procedures have they done. Going to a Cancer Center of Excellence without the above written curriculum vitae details is an assumption.

The Retzius technique may require a single port technique [?]. The multi port on its face would appear to be better for a surgeon. The technology is always secondary to the acquired skills of the
operator.
