Preservation of autonomic nerves to retain genitourinary function without compromise of oncologic clearance has been advocated for left colon and rectal cancer surgery [1, 2]. However, there is still not much information on sexual and bladder function after the curative resection of sigmoid colon cancer [3, 4]. Autonomic nerve preservation during laparoscopic high ligation of the inferior mesenteric artery (IMA) can be difficult and challenging. Using conventional energy dissectors, it is very common to stay close to the autonomic nerves, and as a result, there is a high risk of damage. We therefore decided to perform a high dissection of IMA with CUSA which allowed a clear identification of the branches climbing up all around the IMA, starting from the hypogastric nerves. After the dissection with CUSA, it becomes easy to separate the IMA from the autonomic plexus at its origin and to preserve the nerve anatomy while performing a high ligation.
