Feasibility investigation of uniportal video-assisted thoracoscopic anatomical lung resection for pulmonary sequestration.

ABSTRACT: BACKGROUND:Uniportal video-assisted thoracic surgery (UVATS) technique has been increasingly used for many thoracic diseases. Whether UVATS has equivalent or better perioperative outcomes for pulmonary sequestration (PS) patients remains controversial. Our study aimed to evaluate the feasibility of UVATS in anatomical lung resection for pulmonary sequestration. METHODS:A total of 24 patients with PS including fifteen males and nine females with the mean age of 40 (range, 18-65) years old, who had received completely UVATS anatomical lung resection for PS in Nanjing Chest Hospital between January 2016 and December 2018 were retrospectively reviewed. Related clinical data were retrieved from hospital records and analyzed. RESULTS:All 24 patients had been treated with the UAVTS approach successfully without aberrant artery ruptured or massive hemorrhage, and no patients died during the perioperative period. Overall mean surgery time was 102 mins (range, 55-150 min), the mean blood loss was 94?ml (range, 10-300?ml), the mean days of chest tube maintained were 4?days (range,1-10?days), and the mean postoperative hospitalization days was 6?days (range,2-11?days). All patients were cured, without cough, fever, hemoptysis, and so on, associated with PS, occurring during the average follow-up of 17?months (range, 3-35?months). CONCLUSIONS:Our preliminary results revealed that anatomical lung resection by UVATS is a safe and feasible mini-invasive technique for PS patients, which might be associated with less postoperative pain, reduced paresthesia, better cosmetic results, and faster recovery.

Project description:Background:Cough is one of the shared complications after lung surgery. In this study, a prospective analysis was conducted for exploring the risk factors of persistent cough after uniportal video-assisted thoracoscopic pulmonary resection. Methods:One hundred thirty-five patients with pulmonary nodules who underwent surgical treatment in the same surgical group from November 2019 to January 2020 were enrolled in this prospective study. The severity of cough and its impact on patients' quality of life before and after surgery were assessed by the Mandarin Chinese version of the Leicester cough questionnaire (LCQ-MC), and postoperative cough was tested by the cough visual analog scale (VAS) and cough symptom score (CSS). Risk factors of cough after pulmonary resection (CAP) were determined by univariate and multivariate logistic regression analysis. Results:The incidence of postoperative cough was 24.4% (33 of 135 patients). Univariate analysis showed that gender (female), the surgical site (upper right), the resection (lobectomy), subcarinal lymph node dissection, postoperative acid reflux, length of hospitalization contributed to the development of CAP resection. Multivariate logistic regression analysis showed that the resection (lobectomy) (OR 3.590, 95% CI: 0.637-20.300, P=0.017), subcarinal lymph node dissection (OR 4.420, 95% CI: 1.342-14.554, P=0.001), postoperative acid reflux (OR 13.55, 95% CI: 3.186-57.633, P<0.001) and duration of anesthesia (over 153 minutes, OR 0.987, 95% CI: 0.978-0.997, P=0.011) were independent risk factors for postoperative cough. Conclusions:The application of uniportal video-assisted thoracoscopic techniques to several types of lung surgery are conducive to enhanced recovery after surgery (ERAS). Postoperative cough is related to an ocean of factors, the resection (lobectomy), subcarinal lymph node dissection, postoperative acid reflux, and duration of anesthesia (over 153 minutes) are independent high-risk factors for CAP resection. Trial registration:This study was registered on ClinicalTrials.gov (NCT04204148).

Project description:BackgroundUniportal video-assisted thoracoscopic surgery (U-VATS) has recently emerged as an alternative procedure for non-small cell lung cancer (NSCLC); however, whether U-VATS has advantages over multiportal VATS (M-VATS) remains unknown.MethodsWe performed a systematic review of two databases (Pubmed and Web of Science) to search comparative studies of U-VATS and M-VATS anatomical pulmonary resection for NSCLC. Operative time, blood loss, number of resected lymph nodes, drainage duration, length of postoperative stay, pain in postoperative day 1(POD1) and conversion rates were retrieved to estimate the comparison of outcomes. A subgroup analysis stratified by study type (propensity-matched analysis and randomized-controlled trial versus non-propensity matched analysis) was performed.ResultA total of 20 studies with 4142 patients were included in this meta-analysis. U-VATS was performed on 1869 patients, whereas the other 2173 patients underwent M-VATS. This meta-analysis showed that there was no significant difference in operative time (U-VATS: 146.48 ± 55.07 min versus M-VATS: 171.70 ± 79.40 min, P = 0.81), blood loss (74.49 ± 109.03 mL versus 95.48 ± 133.67 mL, P = 0.18), resected lymph nodes (17.28 ± 9.46 versus 18.31 ± 10.17, P = 0.62), conversion rate (6.18% versus 4.34%, P = 0.14), drainage duration (3.90 ± 2.94 days versus 4.44 ± 3.12 days, p = 0.09), length of postoperative stay (6.16 ± 4.40 days versus 6.45 ± 4.80 days, P = 0.22), and pain in POD1 (3.94 ± 1.68 versus 3.59 ± 2.76, p = 0.07). Subgroup analysis showed the value of PSM and RCT group consistency with overall value.ConclusionThis up-to-date meta-analysis shows that the perioperative outcomes of U-VATS and M-VATS anatomical pulmonary resection are equivalent. In addition, the differences in long-term outcomes of these two approaches are still unclear. Thoracic surgeons should pay more emphasize on providing high-quality and personalized surgical care for patients, to improve the survival ultimately.

Project description:BackgroundIn recent years, opportunities to conduct anatomical segmentectomies for early stage lung cancer, metastatic lung tumor, and so on have been increasing. Generally, uniportal video-assisted thoracoscopic surgery (U-VATS) uncommon segmentectomy is technically more complicated because of limited angulation compared to multiportal VATS (M-VATS) and the need to treat peripheral vessels/bronchi compared to common segmentectomy. This study aimed to determine the safety and feasibility of U-VATS uncommon segmentectomy compared with U-VATS common segmentectomy and M-VATS uncommon segmentectomy.MethodsWe retrospectively reviewed the medical records of 76 patients in the M-VATS group and 45 patients in the U-VATS group who underwent VATS segmentectomy from January 2015 to December 2020. During that period, the perioperative results of U-VATS uncommon (n=22) segmentectomy were compared with those of U-VATS common (n=23) and M-VATS uncommon (n=37) segmentectomy. Uncommon segmentectomy was defined as any segmentectomy other than segmentectomies of the lingual, basilar, or superior segment of the lower lobe (S6), and upper division of the left upper lobe. All patients in our department underwent preoperative three-dimensional computed tomography (3D-CT) angiography and bronchography to image bronchovascular structures and determine the resection line.ResultsPatients characteristics were similar between the U-VATS uncommon segmentectomy group and the U-VATS common segmentectomy group or the M-VATS uncommon segmentectomy group. In U-VATS, there were no significant differences between common and uncommon segmentectomy in operation time, postoperative drainage, postoperative hospitalization, and postoperative complications. Comparing M-VATS and U-VATS uncommon segmentectomies, operation time (145±35 vs. 185±44 min, P<0.001) and postoperative hospitalization (3.1±1.6 vs. 4.2±1.8 days, P=0.02) were significantly shorter in the U-VATS group than in the M-VATS group. There were no significant differences in blood loss, intraoperative bleeding, duration of postoperative drainage and postoperative complications.ConclusionsIn U-VATS, both types of segmentectomies can be achieved with similar results. Moreover, U-VATS shortened operation time and postoperative hospitalization in uncommon segmentectomy compared with conventional M-VATS. U-VATS is a useful approach for uncommon segmentectomy.

Project description:Background Anatomical segmentectomy has become more and more universal in thoracic surgery because of the increasing detection of pulmonary nodules with ground-glass opacity (GGO), most of which proved early staged non-small cell lung cancer (NSCLC) postoperative. With the advantage of preservation of normal lung tissues, segmentectomy may be performed by surgeons when computed tomography (CT) scan shows pure GGO or multiple GGOs appearing. Especially when the patients with poor cardiopulmonary function or severe comorbidities or in the circumstance of bilateral pulmonary GGOs, segmentectomy can provide opportunities to radically resect all lesions. With the development of minimally invasive surgery technology, uniportal video-assisted thoracoscopic surgery (VATS) has become the regular operative route in many medical centers because it can provide less access trauma, less stress response, less pain, shorter hospital stays, and a lower postoperative complication rate and corresponds well with the idea of “minimally invasive”. However, all of the procedures must be performed in one tiny portal, so uniportal VATS anatomical segmentectomy not only needs the skill and patience of surgeons but the effective cooperation of assistants, nurses and anesthetists, and plenty of details must be paid special attention. Case Description Here we present a video of a patient undergoing S1 segmentectomy of right upper lobectomy (RUL) under uniportal VATS. The chief complaints of the patients was that two pure GGOs in the bilateral upper lobe were found by physical examination for 26 months and he had no symptoms. We performed S1 segmentectomy of RUL under uniportal first time and performed trisegmentectomy of left upper lobectomy (LUL) 3 months later. With routinely follow-up, no evidence of relapse and metastasis disease was found. Conclusions We think anatomical segmentectomy under uniportal VATS can be a feasible and safe procedure that reduces trauma and has equivalent oncology outcomes to lobectomy in early-stage lung cancer but need a more experienced medical center to perform.
