A trocar is a surgical instrument with a sharp point and tube and is used to create endoscopic access in the abdomen or chest where endoscopic instruments can be entered \& used in minimally invasive surgical procedures. Xpan has created an FDA Cleared radially dilating trocar (RDT) that is inserted at 3mm and can be expanded to 5mm or 12mm during surgery. The purpose of this research protocol is to demonstrate that a new FDA Cleared Xpan® radially dilating trocar (RDT) system is at least, just as effective as the existing RDT trocar systems. The procedure will be performed using a radially dilating trocar that is inserted at 3mm and can be expanded to 5mm or 12mm during surgery.
