The aim of this study is to compare 3D-laparoscopy versus 2D-laparoscopy with the use of HD resolution in inguinal hernia repair in terms of error rating, performance time and subjective assessment.
Experimental studies have shown that even experienced surgeons gain from stereoscopy when solving both easy and complex tasks. Inguinal hernia repair is a specialist operation and the large flow makes this type of operation suitable for exploring any advantage of three-dimensional laparoscopy for the experienced surgeon.
