‘surface map’ of appendix – a novel tool for pre-operative demonstration of appendicular location with reference to mcburney’s point using multi-detector ct.

The MDCT "surface map" of the appendix is an effective tool that can convey precise information regarding appendix location to the operating surgeon. There are significant variations in the location of the appendicular base with reference to McBurney's point. These variations are more pronounced along the cranio-caudal axis than the medio-lateral axis. Accurate preoperative localization of the appendicular base with MDCT will help surgeons optimize the initial incision for an open appendicectomy, thus, minimize extension-related incision risks.
