Summary
This summary is machine-generated.

No-waiting segmentectomy significantly reduces operative time compared to the modified inflation-deflation method. This optimized approach for pulmonary segmentectomy does not increase complications, offering a faster procedure for patients.

Area of Science:

  • Thoracic Surgery
  • Minimally Invasive Procedures
  • Pulmonary Medicine

Background:

  • Modified inflation-deflation is a standard method for identifying the intersegmental plane in pulmonary segmentectomy.
  • This technique requires a significant waiting period (10-20 minutes) during surgery.
  • An optimized 'no-waiting' technique was developed to streamline the procedure.

Purpose of the Study:

  • To compare the efficacy and safety of the novel 'no-waiting' segmentectomy technique against the modified inflation-deflation method.
  • To evaluate differences in surgical outcomes, including operative time and postoperative recovery.

Main Methods:

  • A comparative study of 123 patients undergoing uniportal video-assisted thoracoscopic segmentectomy for ground-glass nodules.
  • Patients were divided into two groups: modified inflation-deflation (45 patients) and no-waiting segmentectomy (78 patients).
  • Propensity-score matching was employed to control for baseline differences, with 33 pairs successfully matched for analysis.

Main Results:

  • The no-waiting segmentectomy group demonstrated a significantly shorter surgery time (80.12±35.53 min) compared to the modified inflation-deflation group (102.97±48.07 min) after propensity-score matching (P=0.03).
  • No significant differences were observed between the two methods regarding bleeding volume, drainage duration, or length of postoperative hospital stay.
  • The no-waiting procedure involves severing the segmental artery, lung inflation, hilar dissection, and dividing the segmental bronchus consecutively.

Conclusions:

  • No-waiting segmentectomy is a viable and optimized alternative to the modified inflation-deflation method for pulmonary segmentectomy.
  • This technique offers the advantage of reduced operative time without compromising patient safety or increasing postoperative complications.
  • The findings suggest no-waiting segmentectomy as an optional, efficient approach for thoracic surgeons.
