Excerpt
The advantages of the laparoscopic approach for colon cancer have been clearly demonstrated, and there is now growing evidence for the possible role of this type of surgery for rectal cancer [

3]. Initial reports show the technical feasibility of total mesorectal excision, with adequate oncologic clearance and optimal immediate and long-term outcome. The conversion rate ranges between 0% and 20%, and anastomotic leakage is below 20% [

4]. The laparoscopic approach facilitates the procedure, as magnification permits dissection of the lower rectum as far as the supra levator level. Local anatomy (male versus female pelvis, prostate volume, and size of the tumor) may impair adequate dissection, but the most challenging step could be the transection of the lower rectum. Available devices (30, 45, or 60 mm endostaplers, straight or flexible) reach the transection line in an oblique direction when introduced through the right iliac fossa or through a suprapubic trocar. More than one staple loader is usually required to complete the transection, obtaining a zigzag staple line. The distal rectal stump acquires an asymmetric trapezoidal shape whose corners may be poorly irrigated. The usual neoadjuvant therapy with chemoradiotherapy may increase the risk of staple line failure. …
