Area of Science:

Thoracic Surgery
Surgical Technology
Minimally Invasive Procedures

Background:

Mechanical stapling is standard for lung resection.
Complications, though infrequent, can occur with current stapling devices.
A more advanced stapling platform may reduce complication rates.

Purpose of the Study:

To evaluate the safety and reproducibility of a new computer-mediated power stapling platform (SurgASSIST) in 100 patients undergoing anatomic lung resection.
To assess the performance of three types of digital loading units (DLUs) used with the platform.

Main Methods:

Prospective observational study of 100 patients undergoing anatomic lung resections between 2004-2005.
Utilized the SurgASSIST platform with linear, vascular, and bronchial DLUs.

Collected data on operative procedures, staple types, operation duration, chest tube drainage, and hospital stay.

Main Results:

No major operative complications were observed in 100 patients.
One bronchial dehiscence and one incomplete pulmonary vein seal occurred.
15% computer misreads on DLUs were noted; median hospital stay was 5 days.

Conclusions:

Computer-mediated power stapling is safe and reproducible for lung parenchyma and hilar structure stapling during anatomic resection.
The SurgASSIST platform shows promise in reducing stapling-related complications.
Further clinical data is warranted to confirm long-term outcomes.
