Abstract

BACKGROUND:

The role of the human camera holder during laparoscopic surgery keeps valuable personnel from other duties. EndoAssist is a robotic camera-holding device controlled by the operator's head movements. This study assesses its introduction into clinical practice.

METHOD:

Ninety-three patients undergoing laparoscopic cholecystectomy were randomized to have either the robotic (40) or a human (46) assistant. Seven patients converted to open operation were excluded. Six surgeons were evaluated. Operating time and subjective assessments were recorded. Learning curves were constructed.

RESULTS:

The mean operating time was less using the robotic assistant (66 min) than with human assistance (74 min) (p < 0.05, two-tailed t-test). The learning curves for operating time showed that within three operations surgeons were trained in using the robot. The device was safe in use.

CONCLUSION:

The EndoAssist operating device is a significant asset in laparoscopic surgery and a suitable substitute for a human assistant. Surgeons became competent in the use of the robot within three operations. The robot offers stability and good control of the television image in laparoscopic surgery.
