Abstract

Introduction:

The SoloassistĀ® system is a joystick-guided robotic scope holder. We evaluated the efficacy of Soloassist in laparoscopic surgery.

Methods:

We investigated operative time, blood loss, set-up time, length of hospital stay, and the number of participating surgeons in laparoscopic cholecystectomy cases before and after the introduction of Soloassist. Furthermore, we evaluated these factors in each group of 20 elective and emergency cholecystectomy cases by single surgeon after matching their background. To evaluate the performance level of operating Soloassist, we divided the operative field into three areas. Then we counted the frequency of energy device activation in initially 10 cases by a single surgical resident and observed its change.

Results:

The number of participating surgeons was significantly less and postoperative hospital days were fewer in the Soloassist group. There was no significant difference between set-up time and blood loss both in elective and emergency cases. The total number of energy device activations and that in the dangerous area decreased in accordance with the experience.

Conclusion:

Considering our results and previous reports, the combination use of an ideal active scope holder and a commercially available 3D scope is currently considered the best approach in laparoscopic surgery. In the near future, development of active scope holders might play an important role in laparoscopic surgery.
