Background: Posture, vision, and instrumentation limitations are the main predicaments of conventional laparoscopy.
Objective: To combine the ETHOS surgical chair, the three-dimensional laparoscope, and the Radius Surgical System manipulators, and compare the system with conventional laparoscopy and da Vinci in terms of task completion times and discomfort.
Design, Setting, And Participants: Fifteen trainees performed the three main laparoscopic suturing tasks of the Heilbronn training program (IV: simulation of dorsal venous complex suturing; V: circular suturing of tubular structure; and VI: urethrovesical anastomosis) in a pelvi trainer.
Objectives: To present the technique and long-term results of retroperitoneal laparoscopic partial nephrectomy (LPN), focusing on the impact of an ergonomic platform.
Patients And Methods: Between January 2000 and May 2016, 287 patients (193 men, 94 women) underwent LPN performed by four surgeons. The median (range) patient age was 59 (19-85) years, tumour size 3.
Objective: Laparoscopic surgery can be harmful to surgeons requiring a prolonged learning curve due to significant ergonomic drawbacks. Based on preliminary clinical experience, we present an experimental evaluation of the second-generation ETHOS™ operating chair by comparing it with two different operating positions of conventional laparoscopic pelvic surgery.
Materials And Methods: The ETHOS operation platform consists of a seat like a saddle and five more parts that can be adjusted individually to support the surgeon's trunk and extremities.
