BipoJet Scissors as an Alternative to Laser in Lung Wedge Resection

Area of Science:

• Thoracic Surgery
• Surgical Technology
• Pulmonary Medicine

Background:

• Airtight closure of resected lung surfaces is critical in lung resections.
• Various techniques exist, including clamp resection, staplers, lasers, and high-frequency methods.
• This study quantitatively compares air fistulas from BipoJet dissecting scissors and laser resection in porcine lungs.

Purpose of the Study:

• To compare the efficacy of BipoJet dissecting scissors versus laser resection in achieving airtight lung closure.
• To quantitatively measure air fistula volume across resection surfaces.
• To evaluate the practical advantages of BipoJet dissecting scissors in lung parenchyma resection.

Main Methods:

• Wedge resections were performed on porcine lungs using water-irrigated bipolar scissors and laser (1350 nm, 40 watts, non-contact).
• Air fistula volume was measured post-resection.
• The BipoJet technique involved irrigating standard surgical scissors with sodium chloride solution.

Main Results:

• Laser resection achieved slightly better pneumostasis, but the difference was not statistically significant (laser: 124 mL/min/cm², BipoJet: 145 mL/min/cm²).
• BipoJet scissors with water irrigation prevented tissue temperatures from exceeding 100°C, avoiding carbonization.
• BipoJet scissors demonstrated advantages: ease of use, integrated functions, clear surgical field, low cost, and no need for specialized training or protective measures.

Conclusions:

• Lung parenchyma resection, including lung metastases, is facilitated by BipoJet scissors.
• BipoJet scissors provide comparable results to laser resection for airtight closure.
• The study supports BipoJet scissors as a practical and effective alternative for lung resection procedures.
