Summary

The radial stapler option improved lung-conserving wedge resections in a simulation, offering a better mass-to-margin ratio compared to linear staplers alone for thoracoscopic surgery.

Anomalous Lobar Variations in Donor Lung: Challenges and Considerations in Lung Transplantation.

Cureus·2026

Area of Science:

  • Thoracic Surgery
  • Surgical Technology
  • Minimally Invasive Procedures

Background:

  • Lung-conserving wedge resections are crucial for preserving pulmonary function.
  • Current thoracoscopic techniques using linear staplers may present challenges in achieving optimal resection margins.
  • Evaluating novel stapling technology is essential for advancing surgical outcomes.

Purpose of the Study:

  • To compare the efficacy of a radial stapler versus a linear stapler in facilitating lung-conserving wedge resections during thoracoscopic surgery.
  • To assess the impact of stapler type on the mass-to-margin ratio in simulated lung resections.

Main Methods:

  • A video-assisted thoracoscopic simulation using sheep lungs was conducted.
  • Seven cardiothoracic surgeons performed wedge resections with either a linear stapler or the option of a radial stapler.

  • The mass-to-margin ratio was calculated based on specimen weight and resection margin length.

    • Main Results:

    • Radial stapler use resulted in a significantly better mass-to-margin ratio (3.31) compared to linear staplers alone (4.75).
    • This indicates more efficient resection of target tissue with adequate margins when the radial stapler was available.

    Conclusions:

    • The radial stapler option facilitates superior mass-to-margin resection in simulated thoracoscopic wedge resections.
    • This technology may enhance lung-conserving capabilities in thoracic surgery.
    • Further clinical studies are warranted to confirm these findings in human patients.
