Abstract:
Minimally invasive surgery is advancing to new frontiers that attempt to limit patient morbidities while providing excellent surgical outcomes. At the forefront of these efforts is natural orifice surgery, where surgical incisions can theoretically be eliminated. The purpose of this report is to describe the evolution of the clinical development of the natural orifice translumenal endoscopic radical prostatectomy (NOTES RP). It details the early experimental cadaver and animal work and the many challenges encountered to bring this procedure to clinical fruition. While the procedure remains in its infancy the clinical application to human patients shows its potential merit to positively impact the surgical control of prostate cancer. Early clinical experience does not allow the ability to draw definitive conclusions about the procedure at this time but the potential benefits for a new minimally invasive inexpensive treatment for prostate cancer patients is promising.
