Surgeons' perceptions and injuries during and after urologic laparoscopic surgery

OBJECTIVES The biomechanical and mental strains placed on the surgeon while performing laparoscopic procedures are significantly higher compared with open surgical techniques. We undertook this study to assess the prevalence of surgeons' deleterious perceptions or injuries related to laparoscopic urologic surgery. METHODS Members of endourological society were mailed a questionnaire evaluating their laparoscopic experience, total number of standard laparoscopic surgeries (SLS), hand-assisted laparoscopic surgeries (HALS), and robotic-assisted laparoscopic surgeries (RALS) they performed. The subjects reported any neuromuscular or arthritic injuries sustained during laparoscopic surgery, and graded the degree of pain, numbness, and fatigue they experienced. RESULTS A total of 73 urologists completed the questionnaires. The average responder was 44 years old, had completed a median of 117 procedures, and was performing 3 laparoscopic surgeries per week. Neuromuscular or arthritic symptoms during surgery were reported by 22 responders (30%), the most common was finger paresthesia (18%). At the conclusion of HALS, 45% of the surgeons suffered from hand and wrist numbness and 37% reported pain in these areas. A significant association was observed between the risk of sustaining injury during surgery and the total number of laparoscopic procedures performed by the responder (P = 0.016). RALS was the procedure least associated with injuries, and HALS the most. CONCLUSIONS The laparoscopic operating theater is a hostile ergonomic environment. Surgeons' awareness of the common injuries associated with laparoscopic surgery and careful equipment adjustments before surgery are mandatory to minimize injury. Future improvements in instrument design according to ergonomic principles are highly war-ranted.
