ObjectiveTo share the clinical experience of thoracoscopic unidirectional posterolateral basal segmentectomy via inferior pulmonary ligament.MethodsAll the patients were in the healthy lateral position, with endoscopy holes in the 8th intercostal space of the middle axillary line and 2-3 cm operation holes in the 5th intercostal space of the front axillary line. Anatomical segmentectomy of the posterolateral basal vein, bronchus and artery was performed through the inferior pulmonary ligament upward in turn. The clinical data of this group were analyzed retrospectively.ResultsFrom December 2015 to October 2018, 32 patients underwent thoracoscopic unidirectional posterolateral basal segmentectomy, including 8 males and 24 females, aged 13-71 (52.6±13.7) years. All patients successfully completed the operation, including 9 patients of left lower pulmonary posterolateral basal segmentectomy, 23 patients of right lower pulmonary posterolateral basal segmentectomy. The operation time was 80-295 (133.4 ±40.5) minutes, intraoperative bleeding volume was 20-300 (52.6±33.8) mL, drainage time was 2-14 (4.2±2.3) days, hospitalization time was 4-15 (6.9 ±2.4) days. No death occurred during hospitalization. Postoperative complications included atelectasis in 1 patient and persistent pulmonary leakage over 3 days (4 or 6 days respectively) in 2 patients , chylothorax in 1 patient. All of them recovered smoothly after non-operative treatments. Postoperative pathology showed that 29 patients of primary adenocarcinoma or atypical adenomatoid hyperplasia, including 5 patients of adenocarcinoma in situ, 9 patients of micro-invasive adenocarcinoma, 12 patients of invasive adenocarcinoma, 3 patients of atypical adenomatoid hyperplasia. One patient was of intestinal metastatic adenocarcinoma, 1 patient of inflammatory lesion and 1 patient of bronchiectasis. 3-21(9.6±4.6) lymph nodes were resected in the patients with primary pulmonary malignant tumors. And no metastasis was found.ConclusionThe operation of thoracoscopic unidirectional posterolateral basal segmentectomy via inferior pulmonary ligament is easy. There is no need to open intersegmental tissue. It can protect lung tissue better. The operative method is worthy of clinical promotion.
ObjectiveTo explore the safety and feasibility of the application of video-assisted thoracic surgery (VATS) anatomic segmentectomy in single-stage bilateral thoracic surgery for the treatment of bilateral localized bronchiectasis.MethodsFrom June 2014 to June 2018, 19 patients with bilateral localized bronchiectasis underwent single-stage bilateral thoracic surgery with VATS anatomic segmentectomy, including 11 males and 8 females aged 38.0±12.5 years. The clinical efficacy of the surgery was evaluated.ResultsAll surgeries were successfully completed, of which 17 were bilateral VATS, 2 were unilateral VATS with the other lateral converted to thoracotomy. The average number of bilateral resected segments was 4-8 (5.9±1.2). Mean operation time was 330.0±40.0 min and mean blood loss was 150.0±60.0 mL. Mean ventilator-assisted breathing time was 6.0±1.8 h, mean duration of chest-tube placement was 4.0±1.0 d and mean hospital stay time was 14.0±1.5 d. Three patients suffered pulmonary infection and 1 patient received tracheotomy. No perioperative death occurred. Arterial oxygen pressures on postoperative day (POD) 1 (F=340.18, P<0.05) and POD 3 (F=131.26, P<0.05) were significantly lower than that before operation, arterial carbon dioxide pressures on POD 1 (F=46.62, P<0.05) and POD 3 (F=48.21, P<0.05) were significantly higher than that before operation, and pulse oximeter saturation on POD 1 was significantly lower than that before operation (F=210.82, P<0.05). The patients were followed up for one to five years without recurrence.ConclusionApplication of VATS anatomic segmentectomy in single-stage bilateral thoracic surgery for the treatment of bilateral localized bronchiectasis is safe and feasible with strictly selected patients. Postoperative airway management is very important. The surgery is worthy of wide clinical practice.
Objective To examine the application effectiveness of dual 8F ultrafine pigtail drainage tubes versus a single 28F large-bore chest tube in single-port thoracoscopic lobectomy/segmentectomy. Methods Clinical data of patients who underwent single-port video-assisted thoracoscopic lobectomy/segmentectomy within our medical group from January 2020 to August 2023 were retrospectively analyzed. They were categorized into two groups based on postoperative drainage methods: a dual 8F ultrafine pigtail tubes group and a single 28F large-bore chest tube group. Comparative analysis was performed on perioperative data for the two groups of patients. Results The dual 8F ultrafine pigtail tubes group comprised of 68 patients, with 41 females and 27 males, and an average age of (54.72±13.34) years, while the single 28F large-bore chest tube group comprised of 80 patients, with 40 females and 40 males, and an average age of (57.60±11.04) years. There were statistical differences between the two groups in terms of postoperative drainage volume on day 1, day 2, and day 3, total postoperative drainage volume, postoperative tube placement time, postoperative pain score at 48 hours, maximum postoperative pain score, postoperative hospital stay, postoperative complications related to drainage tubes, and emergency use of pain-relieving medication after surgery (P＜0.05). Conclusion After single-port thoracoscopic lobectomy/segmentectomy, the application of dual ultrafine 8F pigtail drainage tubes can lead to a reduction in postoperative drainage volume and shorten the duration of postoperative drainage tube placement and hospital stay, thereby decreasing postoperative pain and the frequency of emergency pain-relieving medication. Moreover, it lowers the incidence of drainage tube-related complications. In alignment with current enhanced recovery after surgery principles, this approach is advantageous for postoperative recovery.
More and more relevant research results show that anatomical segmentectomy has the same effect as traditional lobectomy in the surgical treatment of early-stage non-small cell lung cancer (diameter<2.0 cm). Segmentectomy is more difficult than lobotomy. Nowadays, with the promotion of personalization medicine and precision medicine, three-dimensional technique has been widely applied in the medical field. It has advantages such as preoperative simulation, intraoperative positioning, intraoperative navigation, clinical teaching and so on. It plays a key role in the discovery of local anatomical variation of pulmonary segment. This paper reviewed the clinical application of three-dimensional technique and briefly described the clinical application value of this technique in segmentectomy.
With the wide popularization of low-dose computed tomography screening for lung cancer, the proportion of early detection of lung cancer has increased significantly. Due to the favorable prognosis of ground-glass nodule-lung cancer, a prospective multicenter clinical trial in Japan has confirmed the safety and efficacy of segmentectomy. Identification of the intersegmental plane is one of the key steps in segmentectomy. Understanding its physiological mechanism can provide a theoretical basis for optimizing the identification technique, identifying intersegmental plane more accurately and quickly, improving the surgical effect and reducing complications. This article mainly introduces the identification technology of the intersegmental plane and its physiological mechanism in pulmonary segmentectomy.
Objective To assess the clinical value of preoperative localization coupled with computed tomography (CT) three-dimensional reconstruction in pulmonary nodule-centered uniportal thoracoscopic combined subsegmental/segmental resection. Methods The clinical data of 30 patients of combined subsegmental/segmental resection in our hospital from December 2019 to October 2021 were retrospectively collected. There were 19 males and 11 females with the mean age of 56.4 (32.0-71.0) years. The pulmonary nodules were located by CT-guided injection of glue before operation. The three-dimensional reconstruction image and operation planning were carried out by Mimics 21.0 software. ResultsThe operations were all successfully performed, and there was no conversion to open thoracotomy or lobectomy. The mean tumor diameter was 11.6±3.5 mm, the mean distance between the nodule and the visceral pleura was 13.6±5.6 mm, the mean width of the actual cutting edge was 25.0±6.5 mm, the mean operation time was 110.2±23.8 min, the mean number of lymph node dissection stations was 6.5±2.4, the mean amount of intraoperative bleeding was 50.8±20.3 mL, the mean retention time of thoracic catheter was 3.2±1.1 d, and the mean postoperative hospital stay was 4.5±1.7 d. There was 1 patient of subcutaneous emphysema, 1 patient of atrial fibrillation and 1 patient of blood in sputum. Conclusion Preoperative CT-guided injection of medical glue combined with CT three-dimensional reconstruction of pulmonary bronchus and blood vessels is safe and feasible in pulmonary nodule-centered uniportal thoracoscopic combined subsegmental/segmental resection, which ensures the surgical margin and reserves lung tissues.
ObjectiveTo introduce a new method for identifying intersegmental planes during thoracoscopic segmentectomy using pulmonary circulation single-blocking in the target segment. MethodsTo retrospectively analyze the clinical data of 83 patients who underwent thoracoscopic pulmonary segmentectomy from January 2019 to March 2020 using the pulmonary circulation single-blocking method. There were 33 males and 50 females, with a median age of 54 (46-65) years, and they were divided into a single vein group (SVG, n=31) and a single artery group (SAG, n=52), and the clinical data of two groups were compared. ResultsThe intersegmental planes were identified successfully in both groups and there were no statistically significant differences between the two groups in terms of intersegmental plane management (P=0.823), operating time (P=0.786), intraoperative blood loss (P=0.775), chest drainage time (P=0.659), postoperative hospital stay (P=0.824) or the incidence of postoperative complications (P=1.000). ConclusionThe use of pulmonary circulation single-blocking for intersegmental plane identification during thoracoscopic segmentectomy is safe and feasible, and the intersegmental plane can be satisfactorily identified by the single-blocking of arteries or veins.
Abstract： Objective To evaluate the safety and efficacy of total thoracoscopic anatomic pulmonary segmentectomy for the treatment of early-stage peripheral lung carcinoma, pulmonary metastases and benign pulmonary diseases. Methods We retrospectively analyzed 20 patients who received total thoracoscopic anatomic pulmonary segmentectomy in Zhongshan Hospital of Fudan University from March 2008 to November 2011. There were ten male and ten female patients with a mean age of 58.0（14-86）years. Three ports were used. The pulmonary artery and vein of the segment were dealt with Hem-o-lok or stapler. The bronchi of the segment were dealt with staplers. Staplers were used in peripheral lung of intersegmental plane. Results All the twenty patients underwent total thoracoscopic anatomic segmentectomy successfully without any conversion to thoracoctomy or lobectomy. No perioperative morbidity or mortality occurred. Postoperative pathological examinations showed lung cancer in 10 patients, pulmonary metastases in 3 patients and benign pulmonary diseases in 7 patients. The mean operative time was 133.0（90-240）min. The mean blood loss was 85.0（50-200）ml. The chest tubes were maintained in position for 3.2 （2-7） d. The mean postoperative hospitalization time was 6.7 （4-11）d. Conclusion Total thoracoscopic anatomic pulmonary segmentectomy is a feasible and safe technique to be used selectively for Ⅰa stage lung cancer, pulmonary metastases and benign pulmonary diseases that are not appropriate for wedge resection.
The incidence and mortality of lung cancer are increasing globally. With the spread of CT, more and more early-stage lung cancer can be detected and treated in a timely manner. As the main treatment of lung cancer, thoracoscopic anatomical segmentectomy in the treatment of non-small cell lung cancer is causing concern to the thoracic surgeons. Here, we will discuss the application of thoracoscopic anatomical segmentectomy in the treatment of early non-small cell lung cancer.
