Abstract
Laparoscopic colonic surgery especially requires surgeons to be versed in video depth perception and in the usage of special instruments. Moreover, thorough understanding of the varieties of anatomy laparoscopically observed is very important to perform an accurate operation. In our department a ureteral illumination tube is placed in the ureter of the patient with the risk of injury of the ureter at the time of surgery. The ureteral illumination tube facilitates a sufficient understanding of the laparoscopic anatomy and the dissection of the proper layer of mesenterium.
