Comparison of Efficiencies of Three Techniques for Colon Surgery

Purpose: To determine the most efficient technique for performing a colectomy, we used the methodology of time-motion analysis. Methods: The efficiency of five hand-assisted and six regular laparoscopic colectomies and one open colectomy, performed by four surgeons in three different hospitals, was measured. The open colectomy was analyzed as a...

The influence of experience and camera holding on laparoscopic instrument movements measured with the TrEndo tracking system

Retracting and seeking movements during laparoscopic goal-oriented movements. Is the shortest path length optimal?

Aims- Minimally invasive surgery (MIS) requires a high degree of eye–hand coordination from the surgeon. To facilitate the learning process, objective assessment systems based on analysis of the instruments’ motion are being developed. To investigate the influence of performance on motion characteristics, we examined goaloriented movements in a...
