Abstract: Most colorectal surgeries now are carried out as minimally invasive surgery along with the development and application of laparoscopy. However, the surgical imaging system does not meet the progressing requirement of laparoscopic surgeons. Thanks to the advent of three-dimensional (3D) laparo scopy, a more sophisticated surgical scene with realer images of anatomy is provided to surgeons. It makes identification and manipulation easier, so that to shorten the learning curve. Meanwhile, the 3D laparoscopy is not perfect. But authors believe it will finally be used broadly in colorectal surgery with the improvement of the technology.
