We aimed in our study to present the experimental evaluation of a new operating chair used as a platform (ETHOSTm) for laparoscopic surgery in a training room setting. MATERIAL & METHODS: The operating platform consists of a saddle-like seat, an adjustable chest-support, two individually adjustable armrests, and footrests. Fifteen trainees performed 3 standard suturing exercises in pelvitrainer, namely approximating a linear and U-shaped incision made on the skin of a chicken leg and completing an urethrovesical anastomosis on a pig bladder specimen model using interrupted sutures. The trainees performed each exercise 5 times, standing laterally to pelvi-trainer (“Torero-position”) versus standing behind pelvi-trainer and sitting on ETHOSTm. Primary outcome parameters were time to accomplish the exercise and quality of performance. The average times were noted and the participants filled out a validated questionnaire focusing on ergonomic issues. Statistical analysis was performed with a commercially available software package (SPSS) including Chi-Square test to check for statistical significance (p < 0.05). RESULTS: There was no significant difference in anastomotic times standing behind pelvi-trainer and sitting on ETHOSTM; the difference became significant sitting on ETHOSTM compared to Torero-position which mimicking clinical scenario (40.6 vs. 35.2 minutes). Complaints concerning ergonomic issues were significantly less with ETHOSTM-assisted laparoscopy when comparing conventional laparoscopy (total score 33.1 (20-40) vs. 15.7 (13-24). CONCLUSIONS: Ergonomics of laparoscopy may be significantly improved by the new operating platform, (ETHOSTM-chair) supporting the sitting position of the surgeon with armrests and integrated foot pedals and thus may improve urethrovesical anastomosis times in clinical setting.
