Dual-port thymectomy using subxiphoid approach.

We have previously reported single-port thymectomy (SPT) through an infrasternal approach, a procedure in which the thymus is removed through a single port. The dual-port thymectomy procedure developed by adding another port to the single-port procedure has eliminated the risk of interference between forceps operated by both hands of the surgeon and has thereby significantly simplified operative procedures. This procedure provides the same operative field as that obtained by median sternotomy and has excellent maneuverability of devices. Therefore, the dual-port procedure can be used by surgeons who have not been sufficiently trained for SPT, as an alternative procedure in the event of experiencing technical difficulty during SPT, or as a new approach for thymectomy.
