Abstract:  Minimally invasive surgery has become the focus of modern surgical therapy for colorectal cancer，and as one rising star of it，NOSES has been widely applied and developed in China.Compared with rectal cancer，intracorporeal colonic anastomosis is more complex and difficult.With the continuous development of surgical technology，intracorporeal colonic anastomosis in NOSES becomes mature and diversified.Peristaltic anastomosis and antiperistaltic anastomosis are two main ways classified according to the relationship of anastomosis direction and intestinal peristaltic direction，among which deltashaped anastomosis and overlapped deltashaped anastomosis are the most representative surgical technique respectively.In this artical，we offer a detailed overview of evolution of intracorporeal colonic anastomosis in NOSES，main surgical processes of representative technique and currently relative arguments.After summarization of the key points in intracorporeal colonic anastomosis on the basis of previous researches，we are also looking forward to better intracorporeal colonic anastomosis in NOSES in the future.
