Summary
CT-guided zoning localization improves pulmonary nodule resection accuracy and patient outcomes. This safe and reliable method enhances surgical success rates and reduces complications, offering significant clinical value for treating small or deep nodules.
Area of Science:
- Pulmonary Medicine
- Surgical Oncology
- Medical Imaging
Background:
- Surgical treatment of small pulmonary nodules is increasingly necessary due to rising health awareness.
- Accurate localization of small, deep, or difficult-to-reach pulmonary nodules remains a challenge in routine resection.
- Existing methods may struggle with precision, impacting surgical success rates and patient prognosis.
Purpose of the Study:
- To analyze the clinical application value of CT-guided zoning localization for pulmonary nodules.
- To evaluate the efficacy of CT-guided zoning localization in improving surgical outcomes compared to conventional methods.
- To assess the safety, reliability, and impact on patient recovery of this advanced localization technique.
Main Methods:
- Retrospective analysis of 97 patients with solitary pulmonary nodules treated between June 2021 and August 2021.
- Patients were divided into an observation group (CT-guided localization) and a reference group (conventional resection).
- Comparison of operation rate, 1-year survival rate, recurrence rate, and metastasis rate using statistical bivariate t-calibration and sensitivity/specificity analysis.
Main Results:
- CT-guided zoning localization demonstrated accuracy, safety, and reliability in locating pulmonary nodules.
- The observation group showed significant advantages over the reference group in postoperative survival rate, recurrence rate, and nodule deterioration rate.
- Statistical analysis indicated a significant difference (P < 0.05) favoring the CT-guided method.
Conclusions:
- CT-guided zoning localization is a safe and reliable technique for the surgical treatment of pulmonary nodules.
- This method reduces surgical trauma, improves operation success rates, and lowers postoperative complications.
- The CT-guided zoning localization method holds significant value for clinical promotion in pulmonary nodule management.
