Surgical endoscopy·2026

Thoracoscopic partial pulmonary resection using electrocautery for small lung nodules was compared. The coagulation-suturing (CS) method showed less air leakage than the coagulation (C) method, though CS requires more surgical skill.

Area of Science:

  • Thoracic Surgery
  • Surgical Techniques
  • Pulmonary Medicine

Background:

  • Thoracoscopic partial pulmonary resection is used for small peripheral lung nodules.
  • Electrocautery is an alternative to staplers for pulmonary resection.
  • Surface sealing methods impact postoperative outcomes.

Purpose of the Study:

  • To compare the clinical outcomes of two surface sealing methods after thoracoscopic partial pulmonary resection.
  • To evaluate the efficacy and safety of coagulation (C) method versus coagulation-suturing (CS) method.

Main Methods:

  • Retrospective comparison of C method (Soft Coagulation alone) and CS method (Soft Coagulation with continuous suturing).
  • 19 lesions (18 cases) treated with C method, 20 lesions (19 cases) with CS method.

  • Primary diagnosis was lung cancer in 21 cases.

    • Main Results:

    • Operative time was longer for the CS method.
    • Postoperative air leakage occurred in 4 cases (C method) vs. 1 case (CS method).
    • One patient in the C method group required re-do surgery for air leakage.

    Conclusions:

    • The C method is technically simpler but associated with higher risk of prolonged air leakage.
    • The CS method may reduce air leakage but requires proficiency to optimize operative time.
    • Both methods showed no local recurrence, indicating oncological safety.
