Ergonomics and gynecologic laparoscopic surgery

Abstract

Introduction and objectives: Laparoscopic surgery had demonstrated advantages such as less pain, rapid recovery and surgical precision. There are no national data regarding the impact on surgeon’s health. This is a prospective study on ergonomic evaluation and laparoscopic surgery performed by gynecologists. Methods: Specific evaluation methods were used such as Global workload (NASA-tlx), bio-mechanical load (REBA) and the perception of musculoskeletal discomfort (Body Part Discomfort Scale). Personal opinions and surgery data were collected to explore the existence of technical difficulties. Results: 86.7% of gynecologists cataloged surgery as high level of global workload. Effort and performance variables were most important. Bio-mechanical risk level was classified as medium in the entire population. 60% showed body discomfort during surgery. Regarding technical difficulties, fulcrum effect was present in 46% of surgeons, the same percentage had dry eye symptoms. 68% have a pedal error activation during surgery and felt paresthesia of the thumb. Conclusions: Gynecological laparoscopic surgery has a high overall workload. The gynecologist perceives an important body discomfort and some technical difficulties. It is necessary to incorporate ergonomic measures, to minimize and / or reduce mental and physical risk factors, and thus prevent early wear and future injuries in surgeons.
