procedural time, accuracy of imaged-based movements, and
user satisfaction.
Results Surgical procedures were completed with the Auto-
Lap™ system in 64 cases (97%). The mean overall setup
time of the AutoLap™ system was 4 min (04:08 ± 0.10).
Procedure times were not prolonged due to the use of the
system when compared to literature average. The reported
user satisfaction was 3.85 and 3.96 on a scale of 1 to 5 in two
studies. More than 90% of the image-based movements were
accurate. No system-related adverse events were recorded
while using the system.
Conclusion Safe and efficient use of the core technology
of the AutoLap™ system was demonstrated with high image
stability and good surgeon satisfaction. The results support
further clinical studies that will focus on usability, improved
ergonomics and additional image-based features.

Visualization in endoscopic surgery is a challenge for both
surgeon and camera assistant. The surgeon highly depends
on the camera assistant to provide a stable, centered, and
non-rotated image of the target area and has no control other
than verbal commands or manual correction, which requires
release of one of the instruments.
An often encountered pitfall is that the image is unsta-
ble due to tremor, unintended movements or rotation of the
camera by the surgical assistant. Furthermore, manual con-
trol can also be physically demanding leading to fatigue and
suboptimal control. Inexperienced or inattentive assistants
may displace the camera frequently, make jerky movements,
malposition the laparoscope in relation to the horizon, and
point the camera outside the focus of interest more often
Abstract
Background Robotic camera holders for endoscopic sur-
gery have been available for 20 years but market penetration
is low. The current camera holders are controlled by voice,
joystick, eyeball tracking, or head movements, and this
type of steering has proven to be successful but excessive
disturbance of surgical workflow has blocked widespread
introduction. The Autolap™ system (MST, Israel) uses a
radically different steering concept based on image analysis.
This may improve acceptance by smooth, interactive, and
fast steering. These two studies were conducted to prove safe
and efficient performance of the core technology.
Methods A total of 66 various laparoscopic procedures
were performed with the AutoLap™ by nine experienced
surgeons, in two multi-center studies; 41 cholecystectomies,
13 fundoplications including hiatal hernia repair, 4 endome-
triosis surgeries, 2 inguinal hernia repairs, and 6 (bilateral)
salpingo-oophorectomies. The use of the AutoLap™ system
was evaluated in terms of safety, image stability, setup and
and Other Interventional Techniques
