摘要：A number of clinical trials have demonstrated that the laparoscopic approach for colorectal cancer resection provides the same oncologic results as open surgery along with all clinical benefits of minimally invasive *** the last years,a great effort has been made to research for minimizing parietal trauma,yet for cosmetic reasons and in order to further reduce surgery-related pain and *** techniques,such as natural orifice transluminal endoscopic surgery(NOTES)and single-incision laparoscopy(SIL)have been developed in order to reach the goal of"scarless"*** NOTES may seem not fully suitable or safe for advanced procedures,such as colectomies,SIL is currently regarded as the next major advance in the progress of minimally invasive surgical approaches to colorectal disease that is more feasible in generalized *** small incision through the umbilicus allows surgeons to use familiar standard laparoscopic instruments and thus,perform even complex procedures which require extraction of large surgical specimens orintestinal *** cosmetic result from SIL is also better because the only incision is made through the umbilicus which can hide the wound effectively after ***,SIL raises a number of specific new challenges compared with the laparoscopic conventional approach.A reduced capacity for triangulation,the repeated conflicts between the shafts of the instruments and the difficulties to achieve a correct exposure of the operative field are the most claimed *** use therefore of this new approach for complex colorectal procedures might understandingly be viewed as difficult to implement,especially for oncologic cases.
