Improved laparoscopic operating techniques using a digital enhancement video system.
We conducted a prospective, randomized trial in a piglet model to assess the advantages of a digital enhancement video system during difficult endoscopic procedures. Laparoscopic pelvic lymphadenectomy was performed with either conventional two-dimensional or digitally enhanced videoendoscopy. With equal amounts of extirpated lymph nodes, the operations performed with digitally enhanced videoendoscopy were significantly shorter (left lymphadenectomy p = 0.0001, right lymphadenectomy p = 0.001), had less blood loss and fewer false movements, and were associated with no complications, compared with those performed with a two-dimensional videosystem. Thus the accuracy of difficult laparoscopic techniques can be improved by three-dimensional visual perception.
