Laparoscopy-assisted transanal total mesorectal excision for lower rectal cancer: A feasible and innovative technique

Figure 4 The laparoscopy-assisted transanal total mesorectal excision was divided into the transabdominal and transanal parts. This operation can make full use of the advantages of transabdominal and transanal surgery. Laparoscopic surgery can complete laparoscopic exploration, vascular ligation and lymph node dissection, middle and upper mesentery dissociation, while transanal surgery can complete the lower mesentery migration and specimen removal, and then complete abdominal and transanal anastomosis reconstruction.
