Developing novel non-assistant help operation in dual-portal robotic-assisted thoracic surgery (neoDRATS)

Abstract

Objective

To introduce and evaluate the non-assistant help operation in dual-portal robotic-assisted thoracic surgery (neoDRATS), a novel technique designed to eliminate the need for skilled assistants by using all 4 robotic arms independently during anatomical lung surgery.

Methods

Patients were placed in the lateral decubitus position under general anesthesia with single-lung ventilation. The da Vinci Xi Surgical System was used, with specific configurations for right- and left-side operations. The neoDRATS technique used a 4-cm working port and a 1.8-cm secondary port, with detailed guidelines for optimal setup and robotic arm manipulation.

Results

The neoDRATS approach demonstrated successful surgical outcomes without the need for a skilled assistant. The use of a 0° camera and careful placement of instruments minimized interference within the thoracic cavity. The technique provided smooth operability and minimized postoperative discomfort. Video demonstrations of right and left upper lobectomies are provided to illustrate the approach.

Conclusions

NeoDRATS offers a practical, safe, and minimally invasive alternative to conventional multiportal and uniportal robotic-assisted thoracic surgeries. This technique simplifies the surgical process, particularly in settings with limited availability of skilled assistants, and represents a significant advancement in robotic thoracic surgery. Further refinement and clinical integration of neoDRATS are anticipated as robotic innovations continue to evolve.
