Robot-assisted laparoscopic colorectal surgery.

Colorectal surgery can be difficult at open and laparoscopic surgery. This is particularly the case for rectal surgery deep in the pelvis. In obese males distal rectal dissection can be challenging because of instrument and visual limitations. Robot-assisted laparoscopic colorectal operations do not differ significantly from the standard laparoscopic approach but it has certainly been shown that it is feasible to perform the same operation using robotic assistance for the dissection. This allows the surgeon to benefit from vastly enhanced vision and dexterity, which may ultimately translate into benefit for the patient in terms of reduced operating time, and better preservation of pelvic nerves and other structures.
