Project description:Despite the advances in video-assisted thoracoscopic surgery (VATS), vascular reconstruction of the pulmonary artery (PA) is still infrequently performed by thoracic surgeons because of the technical difficulties and the increased operative risk during thoracoscopy. The few published reports have been performed by using 3-4 incisions. We present the first report of a pulmonary artery reconstruction procedure performed by a single-incision VATS technique. A 73-year old male patient was operated on by the thoracoscopic approach through a single 4-cm incision with no rib spreading. The postoperative recovery was uneventful.
Project description:Drainless video-assisted thoracoscopic (VATS) wedge resection has been demonstrated as feasible in treating various lung diseases. However, it remains unknown whether this surgical technique can be effectively applied to lobectomy. In the current study, we evaluated the perioperative outcome of drainless, minimally invasive lobectomy in patients with lung cancer. A total of 26 lung cancer patients who received surgery-performed pulmonary lobectomy were enrolled. The perioperative outcomes were analyzed based on a propensity score matching a comparison with those who had chest drainage. No major surgical morbidity and mortality was noted during the perioperative period. The mean of postoperative hospital stay was 5.08 ± 2.48 days. There was no significant difference in postoperative hospital stay between the two groups of patients. However, the presence of significant postoperative pain (VAS score > 30) on the first day after surgery was less in the drainless group (34.6% vs. 3.8%; p = 0.005). Our results demonstrated that drainless, minimally invasive lobectomy for selected lung cancer patients is feasible. Further evaluation of its impact on short- and long-term surgical outcomes is required in the future.
Project description:BackgroundThoracoscopic segmentectomy is increasingly used in the surgical treatment of early-stage non-small cell lung cancer. However, it remains unclear whether pulmonary function loss after thoracoscopic lung resection is in direct proportion to the number of resected segments, and thus intentional thoracoscopic segmentectomy has the function-preserving advantage over thoracoscopic lobectomy.MethodsIn this prospective observational study, spirometry tests were performed preoperatively and 6 months postoperatively. The observed functional loss was compared with the expected loss estimated by the segment counting method. Resection extent index was introduced as the number of resected segments to total number of segments in the corresponding lobe. Spirometry changes after thoracoscopic lobectomy and intentional thoracoscopic segmentectomy were compared using propensity score matching.ResultsThere were 338 thoracoscopic lobectomies and 321 thoracoscopic segmentectomies. Overall, the observed pulmonary function loss after segmentectomy was significantly less than after lobectomy. But the observed functional loss was significantly greater than the expected loss after segmentectomy. And pulmonary function loss per segment resected was almost doubled after segmentectomy comparing to lobectomy. For segmentectomies with a resection extent index less than 0.5, especially single segmentectomies, pulmonary function loss was significantly less than after corresponding lobectomies. Otherwise, no significant differences in spirometry changes between lobectomies and segmentectomies were detected.ConclusionsPulmonary function loss after thoracoscopic lung resection cannot be accurately evaluated by the number of resected segments. According to the resection extent index, intentional thoracoscopic segmentectomy may help preserve more pulmonary function than thoracoscopic lobectomy only when less than half of the corresponding lobe are resected.
Project description:This study aimed to retrospectively evaluate the use of sugammadex in patients undergoing video-assisted thoracoscopic surgery (VATS) lobectomy.Data were obtained from medical record review of patients who underwent VATS lobectomy from January 2013 to November 2014. Fifty patients were divided into two groups: the sugammadex group (group S, n = 19) was administered sugammadex 2 mg/kg, while the pyridostigmine group (group P, n = 31) received pyridostigmine 20 mg with glycopyrrolate 0.2 mg or atropine 0.5 mg. The primary endpoint measure was the overall incidence of postoperative pulmonary complications including prolonged air leak, pneumonia, and atelectasis. The secondary endpoint measures were the length of postoperative hospital stay and duration of chest tube insertion.The overall incidence of postoperative pulmonary complications in patients in group S was significantly lower compared with that of group P (5 [26.3%] vs. 17 [54.8%]; P = 0.049). Also, the durations of chest tube insertion (5.0 [4.0-7.0] vs. 7.0 [6.0-8.0] days; P = 0.014) and postoperative hospital stay (8.0 [8.0-10.0] vs. 10.0 [9.0-11.0] days; P = 0.019) were shorter in group S compared with group P. Administration of sugammadex was associated reduced with postoperative pulmonary complications (OR: 0.22; 95% CI: 0.05-0.87; P = 0.031).The use of sugammadex, compared with pyridostigmine, showed a significantly reduced overall incidence of postoperative pulmonary complications and decreased duration of chest tube use and postoperative hospital stay in patients undergoing VATS lobectomy, suggesting that sugammadex might be helpful in improving clinical outcomes in such patients.
Project description:The objective of the present meta-analysis was to evaluate the survival, recurrence rate, and complications in patients with stage I non-small cell lung cancer (NSCLC) who received video-assisted thoracoscopic surgery (VATS) or open lobectomy. A literature search was conducted on June 31, 2012 using combinations of the search terms video-assisted thoracic surgery, open thoracotomy, lobectomy, and non-small-cell lung cancer (NSCLC). Inclusion criteria were: 1) Compared video-assisted thoracic surgery (VATS) lobectomy with open lobectomy. 2) Stage I NSCLC. 2) No previous treatment for lung cancer. 4) Outcome data included 5-year survival rate, complication, and recurrence rate. Tests of heterogeneity, sensitivity, and publication bias were performed. A total of 23 studies (21 retrospective and 2 prospective) met the inclusion criteria. VATS was associated with a longer 5-year survival (odds ratio [OR]?=?1.622, 95% confidence interval [CI] 1.272 to 2.069; P<0.001), higher local recurrence rate (OR?=?2.152, 95% CI 1.349 to 3.434; P?=?0.001), similar distant recurrence rate (OR?=?0.91, 95% CI 0.33 to 2.48; P?=?0.8560), and lower total complication rate (OR?=?0.45, 95% CI 0.24 to 0.84; P?=?0.013) compared to open lobectomy. VATS was also associated with lower rates arrhythmias, prolonged air leakage, and pneumonia but it did not show any statistical significance. Patients with stage I NSCLC undergoing VATS lobectomy had longer survival and fewer complications than those who received open lobectomy.
Project description:BACKGROUND:In recent years, the technique of uniportal video-assisted thoracoscopic surgery has been developed. As a new surgical method, its feasibility and safety have not been generally recognized. The aim of this study is to review the technology in the treatment of lung cancer patients in stage I to part of stage IIIa. METHODS:The clinical data of patients accepted thoracoscopic resection of lung cancer by a same medical group from May 2018 to March 2019 in The First Affiliated Hospital of Soochow University were retrospectively analyzed. After remove of cases that did not meet the requirements, the patients were divided into uniportal group (55 cases) and biportal group (87 cases). The clinical data of the two groups were collected and statistically analyzed. RESULTS:All the 142 patients underwent lobectomy and systemic lymph node dissection. There is no perioperative death in both groups. There was no significant difference in age, location of tumors, pathological type, size of tumors and pathological tumor-node-metastasis (pTNM) staging between uniportal group and biportal group (P>0.05). The operation time [(167.65±43.85) min vs (181.71±51.28) min], the intraoperative bleeding volume [(57.45±50.19) mL vs (87.47±132.54) mL], the indwelling time of drainage tube [(4.82±2.82) d vs (5.84±3.43) d] and the hospital stay [(6.91±3.88) d vs (7.74±3.87) d] were less in uiportal group compared to biportal group, though no significant difference occurred (P>0.05 ). The total drainage volume of uniportal group was significantly lower than that of biportal group [(1,064.82±776.38) mL vs (1,658.71±1,722.38) mL], and the visual analogue score of 24 hours and 72 hours after operation [(4.73±0.73) points vs (5.25±0.74) points; (2.16±0.71) points vs (2.55±0.86) points] were lower in uniportal group (P<0.05). CONCLUSIONS:Uniportal video-assisted thoracoscopic radical resection of lung cancer is safe and feasible for stage I to part of stage IIIa lung cancer patients.
Project description:RATIONALE:Video-assisted thoracoscopic surgery (VATS) and open lobectomy are both standard of care for the treatment of early-stage non-small cell lung cancer (NSCLC) because of equivalent long-term survival. OBJECTIVES:To evaluate whether the improved perioperative outcomes associated with VATS lobectomy are explained by surgeon characteristics, including case volume and specialty training. METHODS:We analyzed the Surveillance, Epidemiology, and End Results-Medicare-linked registry to identify stage I-II NSCLC in patients above 65 years of age. We used a propensity score model to adjust for differences in patient characteristics undergoing VATS versus open lobectomy. Perioperative complications, extended length of stay, and perioperative mortality among patients were compared after adjustment for surgeon's volume and specialty using linear mixed models. We compared survival using a Cox model with robust standard errors. RESULTS:We identified 9,508 patients in the registry who underwent lobectomy for early-stage NSCLC. VATS lobectomies were more commonly performed by high-volume surgeons (P?<?0.001) and thoracic surgeons (P?=?0.01). VATS lobectomy was associated with decreased adjusted odds of cardiovascular complications (odds ratio [OR]?=?0.65; 95% confidence interval [CI]?=?0.47-0.90), thromboembolic complications (OR?=?0.47; 95% CI?=?0.38-0.58), extrapulmonary infections (OR?=?0.75; 95% CI?=?0.61-0.94), extended length of stay (OR?=?0.47; 95% CI?=?0.40-0.56), and perioperative mortality (OR?=?0.33; 95% CI?=?0.23-0.48) even after controlling for differences in surgeon volume and specialty. Long-term survival was equivalent for VATS and open lobectomy (hazard ratio?=?0.95; 95% CI?=?0.85-1.08) after controlling for patient and tumor characteristics, surgeon volume, and specialization. CONCLUSIONS:VATS lobectomy for NSCLC is associated with better postoperative outcomes, but similar long-term survival, compared with open lobectomy among older adults, even after controlling for surgeon experience.
Project description:A 51-year-old man was referred to our hospital, with a dumbbell-shaped nodule measuring 40 mm in the right upper lobe of the lung. He was a current smoker with diabetes mellitus and bronchial asthma. The transbronchial biopsy was performed. However, definitive diagnosis was not obtained from the excised specimens. Bacterial culture of bronchial lavage fluid also yielded negative results, including for tuberculosis. After eight months of observation, the tumour had slightly increased in size. Surgery was planned to resect the tumour for definitive diagnosis. Because of the size of the tumour, a lobectomy of the lung was scheduled with the patient's consent. Four small incisions, each less than 1.2 cm long, were made in the chest wall for thoracoscopic surgery. To remove the specimen, we made a 3-cm longitudinal incision 1 cm below the xiphisternal joint. The patient complained of no chest pain after surgery. The post-operative course was uneventful.
Project description:This is a case report of a 53-year-old woman who presented to our hospital in 2011 with an intermittent cough and dyspnea for 5 years. The chest X-ray showed a prominent left hilum and a smaller right lung. Computed tomography (CT) of the chest confirmed the absence of the right pulmonary artery (PA) and the right cardiac catheterization showed a mean PA pressure of 34 mmHg. Concomitant asthma and unilateral absence of pulmonary artery (UAPA) were diagnosed. In the following years, her functional class remained stable under medications including low-dose sildenafil and spironolactone. In 2020, she developed mild intermittent chest tightness and the coronary angiography showed a fistula between the proximal left circumflex coronary artery and right pulmonary circulation. She declined further intervention for her coronary-pulmonary artery fistula (CPAF) and her symptoms improved spontaneously. To our knowledge, only 16 similar cases with combined UAPA and CPAF in adults have been reported in the literature, of which, pulmonary hypertension was documented in nine patients (56.3%).
