Abstract
BACKGROUND:
With the widespread use of low-dose spiral computed tomography (LDCT) and increasing awareness of personal health, the detection rate of pulmonary nodules is steadily rising.
OBJECTIVE:
To evaluate the success rate and safety of two different models of Hook-Wire needle localization procedures for pulmonary small nodule biopsy.
METHODS:
Ninety-four cases with a total of 97 pulmonary small nodules undergoing needle localization biopsy were retrospectively analyzed. The cases were divided into two groups: Group A, using breast localization needle steel wire (Bard Healthcare Science Co., Ltd.); Group B, using disposable pulmonary nodule puncture needle (SensCure Biotechnology Co., Ltd.). All patients underwent video-assisted thoracoscopic surgery (VATS) for nodule removal on the same day after localization and biopsy. The puncture localization operation time, success rate, complications such as pulmonary hemorrhage, pneumothorax, hemoptysis, and postoperative comfort were observed and compared.
RESULTS:
In Group A, the average localization operation time for 97 nodules was 15.47
CONCLUSIONS:
The disposable pulmonary nodule puncture needle is safer and more effective in pulmonary small nodule localization biopsy, exhibiting increased comfort compared to the breast localization needle. Additionally, the incidence of complications is significantly lower.
Introduction
With the widespread use of low-dose spiral computed tomography (LDCT) and increasing awareness of personal health, the detection rate of pulmonary nodules is steadily rising. Research [1] indicates an incidence of 35.5% for pulmonary nodules, with 0.54% being diagnosed as lung cancer. The National Lung cancer Screening Trial (NLST) results show a 20% reduction in lung cancer mortality with LDCT screening compared to standard chest X-rays [2]. Due to the extensive application of LDCT, more early-stage pulmonary nodules, especially Ground Glass nodules (GGN), are being discovered. Currently, the primary treatment for pulmonary nodules is video-assisted thoracoscopic surgery (VATS), which is an effective, minimally invasive, and feasible therapeutic technique [3]. However, performing VATS for the resection of pulmonary nodules, especially invisible and untouchable GGN, poses significant challenges. Existing literature has highlighted the higher safety of hook-wire needle localization for pulmonary nodules before VATS, not only reducing surgery time but also significantly decreasing the chance of conversion to open thoracotomy.
Various techniques for pulmonary nodule localization have been reported, including Hook-Wire needle, spring coil, liquid material injection localization (methylene blue, etc.), bronchoscopy-assisted CT virtual 3D (three dimensions) assisted localization, each with its own advantages and disadvantages [4]. According to our previous experience and literature review, Hook-Wire needle is the most commonly used and reliable method for localization. However, there is limited comparative research among different models of Hook-Wire needles. In this study, we aim to collect and analyze information on various complications and patient comfort during surgeries involving two different models of needles (breast localization needle and disposable pulmonary nodule puncture needle). Our goal is to explore the effectiveness and safety advantages of these two needle models in nodule biopsy localization.
Materials and methods
This study employed two different models of Hook-Wire localization needles. The first one is the breast localization needle [Bard Healthcare Science (Shanghai) Co., Ltd.] with a standard number: National Medical Devices Registration: 20163771636, specifications: 20 G/10.7 cm. It is a tail-wired localization needle (Group A). The second one is the disposable pulmonary nodule puncture needle [Ningbo SensCure Biotechnology Co., Ltd.] with National Medical Devices Registration: 20193150175, specifications: 20 G/10 cm. It is a tail-soft-wired localization needle (Group B). Surgical time, complications, patient comfort, puncture depth, and other factors were statistically collected and analyzed during the puncture localization to compare the efficiency of the Hook-Wire needle puncture method and its clinical benefits.
Clinical patient data and grouping
Patient data were collected from Xiamen Chang Gung Hospital Radiology Department from June 2019 to April 2023 for CT-guided pulmonary small nodule localization biopsy. A total of 94 patients with 97 pulmonary nodules were included (Table 1), including 46 males and 48 females. Patients using different needles were divided into two groups, namely Group A using the breast localization needle (53 nodules) and Group B using the disposable pulmonary nodule puncture needle (44 nodules).

Discussion
With the increasing use of low-dose spiral CT in health examinations, the proportion of patients with pulmonary nodules requiring surgical treatment is rising. Currently, single-port video-assisted thoracoscopic surgery (VATS) is commonly used for the resection of pulmonary nodules. However, unclear preoperative localization of pulmonary nodules can make it challenging to identify them during thoracoscopic surgery, especially for non-palpable ground glass nodules. This can lead to prolonged surgery times, increased postoperative complications, and ultimately extended hospital stays. Therefore, precise preoperative localization of pulmonary nodules is crucial [6]. Currently, pulmonary nodule localization methods include CT-guided percutaneous puncture-assisted localization, bronchoscopic puncture-assisted localization, and CT virtual 3D-assisted localization [7]. Among the commonly used CT-guided percutaneous puncture-assisted localization methods, there are techniques such as percutaneous Hook-wire localization [8], percutaneous spring coil localization [9, 10], and percutaneous injection of liquid materials for localization (e.g., methylene blue) [11, 12, 13, 14, 15]. Hook-wire localization is the most commonly used method in CT-guided percutaneous puncture-assisted localization [16]. In the two types of needles studied in this paper, Group A’s localization needle has a metal hook at the tip followed by a metal wire. However, the metal wire is prone to displacement and detachment, resulting in a higher failure rate, observed in three cases (5.66%) in this group. The rigid and sharp hook wire causes twisting stress on the lung parenchyma and movement of the chest wall, causing significant discomfort or pain. This leads to an increased likelihood of intraoperative and postoperative alveolar hemorrhage and pneumothorax. Postoperatively, patients can only adopt a passive position due to the strong discomfort caused by the friction and pain of the steel wire, resulting in a poor overall experience. This is generally consistent with literature reports [17]. In contrast, Group B’s soft tail wire conforms better to the puncture hole, causing less friction and traction. Postoperatively, patients can adopt a comfortable position, and the chances of decoupling and subsequent trauma-related alveolar hemorrhage and pneumothorax are significantly reduced.In other literature, the “dragging tail” spring coil localization method requires secondary release of the spring coil, increasing the number of CT scans and posing a risk of localization failure [18]. Additionally, the depth of spring coil release is closely related to the operator’s experience. However, for patients with pleural adhesions and pigmentation on the lung surface, the surgery time and intraoperative nodule removal time are shorter compared to patients localized with methylene blue [19]. In the injection of liquid material localization method, methylene blue is commonly used [21], but its rapid diffusion requires immediate surgery post-puncture, and it is challenging to identify on the lung surface with pigment deposition [22, 23]. Bronchoscopic puncture-assisted localization techniques require the use of electromagnetic navigation bronchoscopy [10, 20], and CT virtual 3D-assisted localization techniques involve the use of 3D printing technology to create a localization template. Both of these techniques have high equipment requirements, and only a few institutions currently employ them. Therefore, finding a safe, accurate, and convenient localization method is crucial for the clinical treatment of pulmonary nodules. In this study, the use of a disposable pulmonary nodule puncture needle effectively reduced the occurrence of decoupling during thoracoscopic surgery. Furthermore, during the surgical process, the CT zone localization method accurately identified the lesion’s position, preventing excessive removal and missection of lung tissue. This not only shortened the surgery time but also reduced trauma to the patient, preserved more lung tissue, lowered the risk of postoperative complications, increased the surgical success rate, and promoted patient recovery. Additionally, compared to the breast localization puncture needle, the disposable pulmonary nodule puncture needle had a lower incidence of complications and significantly higher patient comfort.
Conclusion
In conclusion, among the various preoperative localization methods, the Hook-Wire needle localization method stands out for its simplicity, reliable positioning, high safety, and low complication rate. This study confirms that preoperative localization with a disposable pulmonary nodule puncture needle is safer, with a lower complication rate and higher patient comfort. This approach prevents intraoperative missection and facilitates the smooth progress of VATS surgery. It is worthy of clinical promotion and use.
