Summary
This study introduces a novel physiological method for identifying lung intersegmental planes during segmentectomy. This technique simplifies complex resections, improving surgical outcomes and reducing complications.
Area of Science:
- Thoracic Surgery
- Pulmonary Medicine
- Surgical Techniques
Background:
- Lung segmental resection involves identifying intersegmental planes.
- Simple segmentectomies involve one plane, while complicated types involve multiple planes.
- Accurate identification of intersegmental planes is crucial for successful lung segmentectomy.
Purpose of the Study:
- To present a novel physiological method for identifying intersegmental planes during lung segmentectomy.
- To evaluate the efficacy and convenience of this new technique, especially for complicated resections.
Main Methods:
- The method involves ligating the segmental pulmonary artery and vein.
- The lung lobe is inflated with oxygen, followed by deflation and stapling of the segmental bronchus.
- The intersegmental plane becomes easily detectable after these steps.
Main Results:
- The technique was applied in 117 segmentectomy patients.
- Mean blood loss was 122 ± 193 ml, and mean drainage duration was 3.5 ± 4.8 days.
- Postoperative complications occurred in 12.0% of cases.
Conclusions:
- The physiological method for detecting intersegmental planes is convenient and effective.
- This technique is particularly useful for subsegmental resections, especially complicated types.
- The method aids in simplifying complex lung segmentectomies.
