Project description:ObjectivesTo assess the feasibility and safety of uniportal video-assisted thoracoscopic pulmonary segmentectomy compared with lobectomy by studying early postoperative outcomes.MethodsWe included all patients who underwent uniportal segmentectomy and lobectomy between 2017 and 2022 at Karolinska University Hospital. Early clinical outcomes were compared between the uniportal segmentectomy and lobectomy groups. Differences in baseline characteristics were addressed using inverse probability of treatment weighting.ResultsA total of 833 patients (232 segmentectomy, 601 lobectomy) were included. The number of uniportal operations increased during the study period. Patients in the segmentectomy and lobectomy groups, respectively, had stage I lung cancer in 65% and 43% of the cases; 97% and 94% had no postoperative complications, the median number of lymph node stations sampled was 4 vs 5, and non-radical microscopic resection occurred in 1.7% vs 1.8%. The drains were removed on postoperative day 1 in 75% vs 72% of the patients following segmentectomy and lobectomy, respectively, and 90% vs 89% were discharged directly home.ConclusionsUniportal video-assisted segmentectomy was performed with similar early postoperative clinical results compared with uniportal lobectomy in patients with benign, metastatic or early-stage lung cancer.

Project description:BackgroundUniportal video-assisted thoracic surgery (VATS) basal segmentectomy is technically challenging and requires a deep understanding of the segmental anatomy of the lung. This report describes the uniportal VATS segmentectomy of basal segments using a single-direction approach.MethodsA total of 49 patients who underwent uniportal VATS basal segmentectomy between April 2019 and April 2021 were included in this retrospective study. All the surgeries were conducted using a single-direction approach. The resections of segments 7-8 were mainly performed using the interlobar fissure approach, while the resections of segments 9-10 were performed using the inferior pulmonary ligament approach.ResultsA total of 33 patients underwent a single basal segmentectomy and 16 patients underwent combined basal segmentectomy/sub-segmentectomy. The median operative time was 120 min (range, 60-180 min), and the median blood loss was 20 mL (range, 10-100 mL). The median chest tube duration was 2 days (range, 1-5 days), and the median hospital stay after surgery was 4 days (range, 2-15 days). The morbidity rate after surgery was 6.1% (3/49). There were no perioperative deaths. The pathological examinations revealed 3 cases of adenocarcinoma in situ (AIS), 33 cases of minimally invasive adenocarcinoma, and 13 cases of lepidic-predominant invasive adenocarcinoma. No recrudescence or mortality was reported during the median follow-up time of 7 months (range, 2-25 months).ConclusionsUniportal VATS basal segmentectomy is a feasible and reliable technique based on our experience. This single-direction method allows the uniportal VATS basal segmentectomy to be performed in an easy manner with the targeted segmental bronchi and vessels exposed from superficial to deep in order of their appearance while avoiding the repeated turnover of the lung.

Project description:Recently, uniportal video-assisted thoracic surgery (VATS) has developed rapidly and has become the main theme of global surgical development. The specific, standardized and systematic training of this technology has become an important topic. Specific training in the uniportal VATS approach is crucial to ensure safety and radical treatment. Such training approach, including a direct interaction with experienced surgeons in high-volume centers, is crucial and represents an indispensable step. Another form of training that usually occurs after preceptorship is proctorship: an experienced mentor can be invited to a trainee's own center to provide specific on-site tutelage. Videos published online are commonly used as training material. Technology has allowed the use of different models of simulators for training. The most common model is the use of animal wet laboratory training. Other models, however, have been used mostrecently, such as the use of 3D and VR Technology, virtual reality simulators, and completely artificial models of the human thorax with synthetic lung, vessel, airway, and nodal tissues. A short-duration, high-volume, clinical immersion training, and a long term systematic training in high-volume centers are getting more and more attention. According to the evaluation of students' grading, a diversified training mode is adopted and the targeted training in accordance with different students helps to improve the training effect. We have done some work in systematic and standardized training of uniportal VATS in single center. We believe such training is feasible and absolutely necessary.

Project description:BackgroundAnatomical segmentectomy by uniportal video-assisted thoracoscopic surgery (U-VATS) is a delicate surgical procedure. Hitherto, only few studies have assessed the learning curves of anatomical segmentectomy by U-VATS, with varying data available. The present study aimed to investigate the learning curve and clinical advantages for U-VATS segmentectomy.MethodsThe medical records of patients who underwent U-VATS or non-U-VATS segmentectomy between August 2017 and May 2020 were retrospectively reviewed. Cumulative sum (CUSUM) analysis was employed to illustrate the learning curve of U-VATS segmentectomy. Perioperative parameters were used to determine the structural intervals of the learning curve, and to compare U-VATS and non-U-VATS segmentectomy.ResultsIn total, 122 patients receiving U-VATS segmentectomy and 98 patients receiving non-VATS segmentectomy were included. Of these, 116 patients underwent successful U-VATS segmentectomy, while the other six patients underwent conversions. The structural intervals of 20-29 cases and 58-63 cases were determined as the threshold according to the CUSUM analyses. The learning process of U-VATS segmentectomy was therefore divided into three phases. Interestingly, the perioperative parameters differed significantly between Phases 1 and 3, including operative time (Op-T), postoperative hospital stays (Po-Hst), postoperative thoracic drainage (Po-D), and operative failure (Po-F) rates (P<0.05). Moreover, U-VATS segmentectomy in Phase 3 was associated with significantly shorter Po-Hst and Op-T, less Po-D, and reduced postoperative pain compared with non-U-VATS (P<0.05).ConclusionsU-VATS segmentectomy is an ideal alternative to non-U-VATS segmentectomy. Surgeons can preliminarily complete U-VATS anatomical segmentectomy after performing 20-29 cases, and can master the surgical techniques after completing 58-63 cases.

Project description:AbstractAmongst all minimally invasive oesophagectomies, uniportal video-assisted thoracic surgery (VATS) Ivor-Lewis remains the most challenging procedure due to the skills required for performing the intrathoracic anastomosis. We present an easy and safe circular stapling latero-terminal anastomosis for performing uniportal VATS Ivor-Lewis. The patient had an uneventful post-operative recovery and was disease-free 9 months after surgery.

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:BackgroundThis study aimed to demonstrate the learning curve of anatomical segmentectomy performed by uniportal video-assisted thoracoscopic surgery (U-VATS).MethodWe conducted a retrospective study of U-VATS segmentectomies performed by the same surgeon between September 2019 and August 2022. The learning curve was demonstrated using risk-adjusted cumulative sum (RA-CUSUM) analysis in terms of perioperative complications, which reflected surgical quality and technique proficiency. The surgical outcomes were also compared between different phases.ResultThe complication-based learning curve of U-VATS segmentectomy could be divided into two phases based on RA-CUSUM analysis: phase I, the initial learning phase (cases 1-50) and phase II, the proficiency phase (cases 51-141). Significantly higher complication rates (24.0 vs. 8.8%, p=0.013), longer surgical times (119.8±31.9 vs. 106.2±23.8 min, p=0.005), and more blood loss (20 [IQR, 20-30] vs. 20 [IQR, 10-20] ml, p=0.003) were observed in phase I than in phase II.ConclusionThe learning curve of U-VATS segmentectomy consists of two phases, and at least 50 cases were required to gain technique proficiency and achieve high-quality surgical outcomes.

Project description:BACKGROUND:Segmentectomy can retains more healthy lung tissue than lobectomy, but it remains controversial in oncology for early stage lung cancer. The aim of this study is to discuss the problems of video-assisted thoracic surgery (VATS) segmentectomy in early stage lung cancer, by analyzing the clinical and pathological data of 35 cases and reviewing the literature. METHODS:There were 35 patients who received segmentectomy by complete video-assisted thoracic surgery, from May 2013 to July 2017, in single operation group in the Third Hospital of Peking University. We analyzed the patient's clinical and pathological data, intraoperative and postoperative complications, lymph node number and metastasis its situation, and compared postoperative pathology and preoperative computed tomography (CT) imaging type. In 35 cases of segmentectomy, there were 11 males and 24 females, with an average age of 57.7 years old. The lesions located in the right upper lobe were 8 cases, in the right lower lobe were 8 cases, in the left upper lobe were 13 cases, in the left lower lobe were 6 cases. The mean maximum diameter of CT imaging was 12.7 mm, and the largest diameter of hilar and mediastinal lymph nodes was less than 10 mm. 23 of them were ground glass predominating and 12 were solid components predominating. RESULTS:All 35 cases were successfully completed VATS anatomical segmentectomy. The average operation time was 153 minutes, the amount of bleeding was 51 mL. There were 10 cases of air leakage after operation, all of which were not more than 3 days. There was contralateral atelectasis in 1 case, chylothorax in 1 case. The average length of hospitalization was 6.1 days. There was no other complications outpatient related to surgery, in 30 days after discharge. The pathological changes were as follow, 2 cases of metastatic tumor, 8 cases of benign lung disease and 25 cases of primary lung cancer. In the 25 cases of primary lung cancer, there were 14 cases of invasive lung adenocarcinoma (7 cases were groundglassopacity (GGO) predominating in CT imaging), 4 cases of micro-invasive adenocarcinoma (3 cases were GGO predominating in CT imaging), 6 cases of adenocarcinoma in situ (all were pure GGO in CT imaging), 1 case of lung squamous cell carcinoma (mainly composed of solid in CT imaging). An average of 7.2 lymph nodes were removed in 25 cases of lung cancer, and all lymph nodes had no metastasis. CONCLUSIONS:VATS anatomical segmentectomy is technically safe and reliable, and the indications for lung cancer need to be strictly controlled. Its advantages still need to be confirmed by prospective randomized controlled trials.

Project description:The management of hemothorax (spontaneous or, more often, due to thoracic trauma lesions), follows basic tenets well-respected by cardiothoracic surgeons. In most, a non-operative approach is adequate and safe, with a defined group of patients requiring only tube thoracostomy. Only a minority of patients need a surgical intervention due to retained hemothorax, persistent bleeding or incoming complications, as pleural empyema or entrapped lung. In the early 1990s, the rapid technological developments determined an increase of diagnostic and therapeutical indications for multiport video-assisted thoracoscopic surgery (VATS) as the gold standard therapy for retained and persistent hemothorax, allowing an earlier diagnosis, total clots removal and better tubes placement with less morbidity, reduced post-operative pain and shorter hospital stay. There is no consensus in the literature regarding the timing for draining hemothorax, but best results are obtained when the drainage is performed within the first 5 days after the onset. The traditional multi-port approach has evolved in the last years into an uniportal approach that mimics open surgical vantage points utilizing a non-rib-spreading single small incision. Currently, in experienced hands, this technique is used for diagnostic and therapeutic interventions as hemothorax evacuation as like as the more complex procedures, such as lobectomies or bronchial sleeve and vascular reconstructions.
