Early detection and resection of lesions is an important strategy to improve the survival rate of patients with early-stage lung cancer. Preoperative pathological diagnosis is the “gold standard” for determining the benignity and malignancy of tissue, and preoperative pathological diagnosis includes needle aspiration biopsy (NP) and excisional biopsy (EP). EP is preferred by physicians because the latter preserves the integrity of the lesion for evaluation by the pathologist. To reduce post-biopsy complications, EP is often performed with the aid of thoracoscopic surgery (VATS), and its final clinical outcome is comparable to that of open-heart surgical tissue biopsy. However, during VATS tissue biopsy, the physician can only locate or finger palpate lung nodules in 45% of patients. Localization is more difficult if the nodules are too small in diameter (<10 mm), too far from the chest wall (>5 mm), or are semi-solid or grossly glassy. Patients with failed localization will have to undergo lobectomy or conversion to open-heart surgery. The currently feasible VATS-assisted EP localization methods have their own limitations: the success rate of the finger-touch method is less than 40%; intraoperative ultrasound scanning is too insensitive for patients with emphysema; the incidence of pneumothorax and the degree of compression are higher with wire hook localization; and dye localization tends to spread, compromising the accuracy of the procedure. With this in mind, Dr. Finley at the University of British Columbia, UK, developed a spring coil for localizing lesions for wedge resection. He conducted a prospective clinical study to evaluate the impact of preoperative coil positioning on diagnosis and surgery. The results of the study were published in the journal J THORAC CARDIOV SUR. The study included 56 patients, 29 of whom underwent preoperative CT-guided coil localization, while the rest served as a control group and underwent VATS directly. The results showed no difference in the size, shape, or distance from the chest wall of the patients’ nodules. Patients with preoperative coil localization had a higher wedge resection rate (27/29 versus 13/27), shorter lesion resection time (37 min versus 100 min)/operative time (121 min versus 331 min), and less consumption of the cutting suture staple bin (3.7 versus 5.9) compared to the control group. In addition, there was no difference in the total cost between the two groups, and no death occurred within 90 days after the end of the procedure, and none of the patients with pathologically diagnosed tumors showed recurrence. The use of coils did not increase the financial burden on the patients, as the analysis showed that the cost of the coils was offset by the higher consumption of cut and stapled positions in the control group, so there was no difference in the total cost of hospitalization between the two groups. The high accuracy of positioning (less likely to be displaced); 3. Low compression of the pneumothorax; 4. Minimizing the impact on the tissue specimen and facilitating the pathologist’s handling and description of the specimen.
