Ergonomics in laparoendoscopic single-site surgery: survey results.

Background: Ergonomic issues are frequently reported by surgeons performing laparoendoscopic single-site (LESS) surgery. However, few studies have analysed this issue.

Methods: We used a web format survey to evaluate the opinion of surgeons with experience in this laparoscopic technique. This survey collected demographic information, surgical experience, physical and psychological symptoms, and technical problems related to this type of surgery.

Results: Some 78 surgeons filled out the questionnaire. All participants had clinical experience in this type of laparoscopic approach, and 68 % had performed more than 30 procedures. Two or more musculoskeletal symptoms were reported during or after performing LESS surgery by 81 % of all surgeons. Surgeons with more experience in this approach reported fewer symptoms and technical difficulties.

Conclusions: LESS surgery is accompanied by musculoskeletal problems and technical difficulties for surgeons. Technological advancements and greater surgical experience in the technique will alleviate these issues. More in-depth ergonomic studies are needed.
