[The sutureless lung resection with Ligasure device: the possibilities and perspectives]

Area of Science:

• Thoracic Surgery
• Biomaterials Science
• Surgical Technology

Context:

• Lung resections often require secure tissue closure.
• Collagen-based sutures are utilized for lung tissue approximation.
• The Ligasure device presents a novel energy-based sealing technology.

Purpose:

• To evaluate the durability and safety of collagen sutures used with the Ligasure device in lung resections.
• To determine the rupture pressure of collagen sutures in different lung tissue types.
• To assess the incidence of complications, such as prolonged air leakage, following the use of this technique.

Summary:

• An experimental study involving 17 patients undergoing 21 lung resections assessed collagen suture durability using the Ligasure device.
• The average rupture pressure for collagen sutures was 413±99.4 mm Hg in intact lung parenchyma and 212±66.7 mm Hg in emphysematous tissue.
• Prolonged air leakage occurred in only two cases, indicating a low complication rate.

Impact:

• The Ligasure device demonstrates high effectiveness and safety for suturing lung tissue during thoracic surgery.
• This technology may improve outcomes and reduce complications in patients undergoing lung resection.
• Findings support the adoption of energy-based sealing devices for enhanced surgical performance in pulmonary procedures.
