The aim of this study was to examine the advantages and risks of the Automated Endoscopic System for Optical Positioning (AESOP) 3000 robot system during uncomplicated laparoscopic cholecystectomies or laparoscopic hernioplasty.


In a randomized study, we examined two groups of 120 patients each with the diagnosis cholecystolithiasis respectively the unilateral inguinal hernia. We worked with the AESOP 3000, a robotic arm system that is voice-controlled by the surgeon. The subjective and objective comfort of the surgeon as well as the course and length of the operation were measured.


The robot-assisted operations required significantly longer preparation and operation times. With regard to the necessary commands and manual camera corrections, the assistant group was favored. The same was true for the subjective evaluation of the surgical course by the surgeon.


Our study showed that the use of AESOP during laparoscopic cholecystectomy and hernioplasty is possible in 94% of all cases. The surgeon must accept a definite loss of comfort as well as a certain loss of time against the advantage of saving on personnel.
