ObjectiveTo emphasize the important role of video-assisted thoracoscopic surgery (VATS) in treatment of mediastinal bronchogenic cysts (MBCs).MethodsWe retrospectively reviewed the clinical data of 112 patients (53 males and 59 females) of mediastinal bronchogenic cysts who underwent VATS in our institution between April 2001 and Aprial 2016. Median age was 4–75 (45.6±15.0) years. All patients underwent chest CT preoperatively. The patients were divided into two groups: an anterior mediastinum group, 47 patients; a middle and posterior mediastinum group, 65 patients including 35 patients in the middle mediastinum, 30 patients in the posterior mediastinum. The average diameter was 0.5–22.0 (3.50±2.33) cm. The average CT attenuation was 0–67 (35.5±15.3) Hu on unenhanced CT. We began each operation with the VATS technique.ResultsThe CT diagnostic accuracy for group middle and posterior mediastinum with CT value≤20 Hu was higher than others (61.5% vs. 13.1%, χ2=17.675, P<0.001). A total of 111 patients underwent VATS, only one patient converted to open thoracotomy. Cyst resection and thymectomy were conducted in 45 patients, cyst resection and extended thymectomy were conducted in 2 patients in the anterior mediastinum group. Simply cyst resection were performed in the middle and posterior mediastinum group (n=65). The average operative time was 40–360 (104.5±43.1) min. The average intraoperative blood loss was 5–600 (57.9±88.9) mL. The intraoperative complication rate was 3.6% and the incomplete resection rate was 6.3%. The main reason for these was severe adhesion between the cyst and mediastinal structure. No serious postoperative complication was found. Follow-up was done in 99 patients, and the mean follow-up time was 42 (12–191) months. There was no local recurrence.ConclusionVATS resection of MBCs is a safe and efficacious procedure, and minimally invasive and surgical resection should be performed as early as possible for MBCs.
Abstract: Objective To summarize the clinical experiences of applying completely videoassisted thoracoscopic lobectomy in pulmonary diseases treatment, and evaluate its safety, indication and efficacy. Methods We retrospectively analyzed the clinical data of 47 patients with pulmonary diseases undergoing completely videoassisted thoracoscopic lobectomy at the First People’s Hospital of Yunnan Province between October 2008 and November 2010. Among the patients, there were 35 males and 12 females with their age ranged from 30 to 72 years averaging at 61.5 years. Adenocarcinoma was present in 27 patients, squamous carcinoma in 9 patients, small cell carcinoma in 1 patient, tuberculosis in 3 patients, bronchiectasis in 3 patients, pulmonary inflammatory pseudotumor in 2 patients, hamartoma in 1 patient, and giant bulla in 1 patient. All patients underwent completely videoassisted thoracoscopic lobectomy which was carried out through three miniinvasive incisions without the use of rib spreader. Systemic lymph node dissection was performed for patients with malignancies. Blood loss, operation time, the rate of conversion to thoracotomy, postoperative hospital stay, and complications were observed. Results Completely videoassisted thoracoscopic lobectomy was successfully performed in 44 patients, and the other 3 patients were changed to open thoracotomy due to bleeding in one patient, T3 tumor in one patient and accidentally injured bronchus in one patient. The overall conversion rate was 6.4% (3/47). The mean operation time, blood loss and postoperative hospital stay were respectively 120±45 minutes, 150±80 ml, and 7±2 days. No perioperative death occurred. There were 9 patients of complications including lymphatic fistula, air leak, atrial fibrillation and atelectasis, and they all recovered after conservative treatment. Fortyfour- patients were followed up for -1 to 23 months with 3 patients missing. One-patient had bloody sputum during the followup, but recovered spontaneously later. Brain metastasis occurred to a stage Ⅲa patient with primary lung cancer 9 months after operation, and the patient survived after treatment with gamma knife. No recurrence happened to the other patients and their quality of life was good. Conclusion Completely videoassisted thoracoscopic lobectomy is a safe and feasible surgical procedure for patients with earlystage lung cancer and benign pulmonary lesions which need lobectomy. However, it is necessary to select the patients carefully in the early period of practising.
ObjectiveTo investigate the feasibility of video-assisted thoracoscopic surgery (VATS) lung resection in the treatment of tuberculosis.MethodsWe retrospectively analyzed the clinical data of 164 tuberculosis patients who underwent lung resection in Xi'an Chest Hospital from 2013 to 2017. Patients were divided into two groups according to the surgical procedure: a VATS group (85 patients, 56 males and29 females) and a thoracotomy group (79 patients, 52 males and 27 females). The clinical effect of the two groups was compared.Results Compared to the thoracotomy group, the VATS group had less operation time (151.59±76.75 min vs. 233.48±93.89 min, P<0.001), amount of intraoperative blood loss (200.00 ml vs. 600.00 ml, P<0.001), the postoperative drainage (575.00 ml vs. 1 110.00 ml, P=0.001), extubation time (4 d vs. 6 d, P<0.001) and hospital stay (13.00 d vs. 17.00 d, P<0.001). There was no statistical difference in postoperative complications (10 patients vs.17 patients, P=0.092) between the two groups. A total of 97 patients underwent lobectomy, including 36 of the VATS group and 61 of the thoracotomy group. The operation time (211.39±70.88 min vs. 258.20±87.16 min, P=0.008), the intraoperative blood loss (400.00 ml vs. 700 ml, P<0.010), the postoperative drainage (800.00 ml vs. 1 250.00 ml, P=0.001), extubation time (5.00 d vs. 8.00 d, P=0.002) and hospital stay (13.11±4.45 d vs. 19.46±7.74 d, P<0.010) in the VATS group were significantly better than those in the thoracotomy group. There was no statistical difference in postoperative complication rate (4 patients vs. 14 patients, P=0.147) between the two[1], groups.ConclusionCompared with conventional thoracotomy, VATS lung resection has obvious advantages in treatment of tuberculosis, which may be the preferred technique.
Recently, the frequency of lung disease appears higher and more precise than previously estimated. Small pulmonary nodules (SPNs) are frequently detected on high-resolution computed tomography (CT) scans. For the reason of high rate of false positives by fine needle aspirate biopsy, small lung nodules often can not be confirmed by monitor or palpation with forceps. How to precisely locate and mark the nodule before the surgery is one of the most important things for video-assisted thoracoscopic surgery (VATS). We reviews the methods of location the pulmonary nodules before the surgery and analyzes the advantages and disadvantages of various methods.
Objective To investigate the feasibility and safety of uniportal video-assisted thoracic surgery (VATS) for primary lung cancer. Methods We retrospectively analyzed the clinical data of 95 primary lung cancer patients in our hospital between January 2014 and January 2015. The patients were divided into an observation group (45 patients) and a control group (50 patients). Standard thoracoscopy lobectomy was used in the control group. Uniportal thoracoscopy lobectomy was used in the trial group. The parameters of the two groups were observed. Results The surgeries of the two groups were successfully completed. There was no statistical difference in operative time, intraoperative transit rate, blood loss, number of lymph node dissection, thoracic drainage and pathology Ⅰ, Ⅱ period (P>0.05). Postoperative drainage tube time, postoperative hospital stay, postoperative pain in the observation group were better than those in the control group (P<0.05). But postoperative drainage time in the observation group was longer than that in the control group (P<0.05). Also, the total hospital costs, especially on the use of expensive consumables, during surgery in the observation group was higher. And there was a higher risk of delayed incision healing or airway injury (P<0.05) in the observation group. One death in the control group during perioperative period occurred. Conclusion Uniportal VATS operation applied in radical operation for lung cancer is safe and feasible. It accelerates postoperative turnover, reduces postoperative pain. But there is a higher risk for airway injury or delayed wound healing, and an increase in use of medical consumptive stuff.
Abstract: Objective To discuss the security, effectiveness and risk factors of videoassisted thoracoscopic surgery for posterior mediastinal tumors. Methods We retrospectively analyzed the data of 59 patients including 36 men and 23 women who underwent thoracoscopic resection of posterior mediastinal tumors in People’s Hospital of Peking University from May 2001 to July 2009. Their age ranged from 6 to 73 years old with an average age of 40.6 years old. The average maximum diameter of the tumors was 4.86 cm. All procedures were performed under general anesthesia and tumors were cut out with three ports. The anterior port was extended to 6 to 10 cm when conversion to thoracotomy was needed. After mediastinal pleura were opened, the tumor was stripped out along the outside of peplos and the vascular pedicle nerves were managed respectively. Results All surgeries were carried out successfully. The surgical duration, perioperative blood loss, postoperative chest tube duration and postoperative stay in hospital were respectively 45-300 min(125.80±57.40 min), 10-1 000 ml(168.10±157.70 ml), 1-10 d(2.50±1.74 d), and 2-14 d(5.24±2.24 d). There were 6 cases of conversion to open thoracotomy with a conversion rate of 10.2%. Postoperative pathology showed that there were 46 cases of neurogenic tumors, 10 cases of cyst, 2 cases of teratoma, and 1 case of lipoma. Follow-up was done on 51 cases for a period of 7-108 months(55.0±24.0 months) and 8(13.6%) cases were missed out during the period. No recurrence or death occurred during the followup. Logistic multivariable analysis showed that maximum diameter of the tumor ≥6 cm was the independent risk factor for extending operative time (OR=1.932，P=0.004), increasing perioperative blood loss (OR=2.267，P=0.002), increasing conversion rate to thoracotomy (OR=3.123，P=0.004) and increasing postoperative complication rate (OR=1.778，P=0.013). Conclusion Videoassisted thoracoscopic surgery for posterior mediastinal tumor is safe and effective. Maximum diameter of the tumor ≥6 cm is an independent risk factor for increasing operation difficulty and risk.
Objective To share the clinical experience of video-assisted thoracoscopic surgery (VATS) anatomic basal segmentectomy by single-direction method. Methods The clinical data of 352 patients who underwent VATS anatomic basal segmentectomy in West China Hospital between April 2015 and April 2021 were retrospectively reviewed, including 96 males and 256 females with a median age of 50 (range, 26-81) years. All basal segmentectomies were performed under thoracoscopy, through the interlobar fissure or inferior pulmonary ligament approach, and following the strategy of single-direction and the method of "stem-branch". ResultsAll patients underwent basal segmentectomy successfully (49 patients of uniportal procedure, 3 patients of biportal procedure and 300 patients of triportal procedure) without addition of incisions or conversion to thoracotomy and lobectomy. The median operation time was 118 (range, 45-340) min, median intraoperative blood loss was 20 (range, 5-500) mL, median drainage time was 2 (range, 1-22) d and median postoperative hospital stay was 4 (range, 2-24) d. The postoperative complications included pneumonia in 6 patients, prolonged drainage (air leakage duration＞5 d or drainage duration＞7 d) in 18 patients, cerebral infarction in 1 patient and other complications in 2 patients. All patients were treated well and discharged without main complaints. No perioperative death happened. ConclusionVATS anatomic basal segmentectomy is feasible and safe. It can be performed in a simple manner following the strategy of single-direction.
