[Safety and validity of port-less forceps in reduced-port surgery for laparoscopic resection of colorectal cancer].

: The purpose of this study was to examine the safety and validity of reduced-port surgery( RPS) in comparison with conventional laparoscopic surgery for colorectal cancer. We investigated 64 cases of colorectal cancer( CRC) resected by laparoscopic surgery at our hospital in 2012, including 22 cases resected by RPS using 1 or more port-less forceps( Endo Relief, Hope Electronics, Japan). With regard to safety, Endo Relief yielded satisfactory outcomes in terms of the limitations of other needlescopic devices, such as lack of strength and risk of tissue injury, while maintaining countertraction. In addition to the original reasons for introducing RPS, such as lessening wound pain and improving the cosmetic outcome after surgery, the advantages of RPS for CRC are high cost efficiency and the possibility of using additional forceps to maintain triangulation or countertraction during laparoscopic surgery. Because it involves a port-less system, RPS facilitates the frequent reuse of forceps, thereby contributing to its high cost efficiency. In the introduction of RPS for laparoscopic colorectal resection, the use of port-less forceps for countertraction could be safe and effective.
