Project description:ObjectiveThe right middle lobe subsegmentectomy (including multisubsegmentectomy and subsubsegmentectomy) has never been reported. This study aimed to describe a thoracoscopic right middle lobe subsegmentectomy.MethodsThis retrospective study included 94 patients who underwent thoracoscopic right middle lobe subsegmentectomy between August 2018 and February 2021. All procedures were performed with the help of the preoperative 3-dimensional computed tomography bronchography and angiography.ResultsNinety-four patients underwent thoracoscopic right middle lobe subsegmentectomy. The median operative time was 56 minutes (range, 35-86 minutes) and median blood loss was 86 mL (range, 50-150 mL). The median duration of chest tube retention was 2.5 days (range, 1-4 days). There were neither cases of postoperative right middle lobe torsion nor instances of perioperative death. The median size of the tumor in the resected segment was 1.3 cm (range, 1.1-1.8 cm). The median margin was 3.3 cm (range, 2.9-4.3). There were 88 cases of lung cancer and 6 cases of benign lesions. The median number of N1 lymph nodes sampled was 3 (range, 2-4). No lymph node involvement was observed postoperatively. No recurrence or mortality was observed during the median follow-up period of 26 months (range, 6-36 months).ConclusionsThoracoscopic right middle lobe subsegmentectomy is feasible and safe. It may be valuable to preserve the lung parenchyma in patients with noninvasive lung cancer, multiple lung cancer, and benign diseases. Long-term lung function, survival, and cancer-free data are being collected.

A combined subsegmentectomy of right S9 + 10b with single direction thoracoscopic surgery.

Project description:Segmentectomy is widely used to treat pulmonary nodules and more functional lungs can be preserved in patients. For pulmonary nodules deep near the intersegmental border, only one single segmentectomy may not achieve adequate surgical margins, and combined subsegmental resection becomes the most suitable treatment option. Thoracoscopic combined anatomical resections involving both of right S9 and S10b are one of the most challenging cases, especially in the right chest. We previously reported a case of combined subsegmental resection of the left complex basal segment (LS9b + 10b). To our knowledge, there has been no report of combined subsegmental resection of the right S9 and S10b. Here, we aim to introduce a different technique named as "open-gate", which means that the intersegmental border between S7 and S10 was cut open along the intersegmental septa, to deal with complex combined basal subsegmental resections.

Uniportal Thoracoscopic Single-Direction Basal Subsegmentectomy (Left S10a+ci): Trans-Inferior-Pulmonary-Ligament Approach.

Project description:Thoracoscopic segmentectomy and subsegmentectomy have been widely accepted for the treatment of peripheral small lung cancers. Thoracoscopic basal subsegmentectomy, especially when performed through a uniportal procedure, is extremely technically challenging, and therefore there are seldom reports of its technical details. In this article, we present a uniportal thoracoscopic left S10a+ci subsegmentectomy following the single-direction strategy through the inferior pulmonary ligament approach.

Prophylactic air-extraction strategy after thoracoscopic wedge resection.

Project description:BackgroundSince the conception of enhanced recovery after surgery protocols, tubeless strategies have become popular. Herein, we introduce a previously unreported alternative air-extraction strategy for patients who have undergone thoracoscopic wedge resection and explore its feasibility and safety.MethodsBetween January 2015 and June 2017, 264 consecutive patients underwent thoracoscopic wedge resection with different drainage strategies. Patients were divided according to the postoperative drainage strategies used: routine chest tube drainage (RT group), complete omission of chest tube drainage (OT group), and prophylactic air-extraction catheter insertion procedure (PC group). Using the propensity score matching method, clinical parameters and objective operative qualities were compared among the three groups.ResultsOptimal 1:1 matching was used to form pairs of RT (n =36) and PC (n =36) groups and balance baseline characteristics among the three groups. The incidence rates of pneumothorax were 5.6% (2/36), 9.8% (5/51), and 19.4% (7/36) in the RT, OT, and PC groups, respectively (P = 0.07). Chest tube reinsertion incidence for postoperative pneumothorax was 19.4% (1/7) in the PC group and 60% (3/5) in the OT group. Other postoperative complications were comparable among these groups.ConclusionsThe prophylactic air-extraction strategy may be an alternative procedure for selected patients. Remedial air extraction may reduce the occurrence of chest tube reinsertion for pneumothorax patients, but further investigation is required.

Robotic versus thoracoscopic combined anatomic subsegmentectomy for early-stage lung cancer: early results of a cohort study.

Project description:BackgroundCombined anatomic subsegmentectomy performed by video-assisted thoracic surgery or robot-assisted thoracic surgery is an emerging minimally invasive surgical technique for patients with early-stage non-small cell lung cancer (NSCLC). However, the early results of these two methods have barely been studied.MethodsA retrospective analysis of medical records from Shanghai Ruijin Hospital between July 2017 and August 2021 included 62 patients, 32 of whom underwent video-assisted combined anatomic pulmonary subsegmentectomy and 30 underwent robot-assisted combined anatomic pulmonary subsegmentectomy. Perioperative outcomes were compared.ResultsSixty-two patients with comparable baseline characteristics were included in this study. No signiﬁcant difference was found in the length of postoperative hospital stay, operation duration, intraoperative blood loss and the rate of overall complications between the robot-assisted and video-assisted groups. A higher cost was observed in the robot-assisted group compared to the video-assisted group. There were more N1 lymph nodes and N1 stations dissected in the robot-assisted group compared with the video-assisted group; the same results were observed with regard to the number of N2 lymph nodes and N2 stations dissected.ConclusionsIt is safe and feasible for the patients with early-stage NSCLC to be treated with combined anatomic subsegmentectomy performed via robot-assisted or video-assisted thoracic surgery. The robotic approach may contribute to the potential improvements in N1 and N2 lymph node retrieval.

Video-assisted thoracoscopic hilar and pericardial release for long-segment tracheal resections.

Project description:Long-segment tracheal resection is technically challenging due to its high tension during reconstruction. Therefore, tracheal release maneuvers, including pulmonary hilar release and pericardial dissection, were required to reduce the anastomotic tension. Traditional hilar release is performed via thoracotomy; however, this approach is invasive. We report a case of bilateral hilar and pericardial release via a video-assisted thoracoscopic surgery (VATS) approach in resecting a long segment tracheal adenoid cystic carcinoma that spanned 50% of the trachea. The bilateral hilar and pericardial releases were performed under general anesthesia through biportal VATS, which contributed to a total of 2.5 cm of additional mobility to the trachea, and the infrahyoid release was then performed through a cervical collar incision. The tumor-involved tracheal segments were removed via median sternotomy, totaling 6.0 cm in length, and the remaining trachea could be successfully reconstructed with a tension-free anastomosis. The total operative duration was 4.5 hours. The patient suffered a transient swallowing dysfunction during the postoperative course, with a good luminal patency in the trachea after 1 month postoperatively. Therefore, bilateral hilar release via VATS can be considered to be a less invasive, avoiding the potential complications related to a thoracotomy, but similarly effective release maneuver for long-segment tracheal resections.

Uniportal video-assisted thoracoscopic lung sparing tracheo-bronchial and carinal sleeve resections.

Project description:Pathology arising from the intrathoracic portion of the trachea (distal trachea), the carina and the main bronchi is usually neoplastic and is mainly treated with surgery. Resection of the intrathoracic portion of the trachea, the carina and the main bronchi for neoplastic lesions does not necessitate lung resection and is traditionally being conducted via open surgery. Video-assisted thoracic surgery (VATS) is witnessing an exponential growth and is the treatment of choice for early-stage non-small cell lung cancer (NSCLC). The experience accumulated over the past two decades along with the introduction of reliable and ergonomic technology, has led to the expansion of its indications. In this article we provide a detailed description of lung sparing distal tracheal, carinal and main bronchi resection for primary neoplasms of the airway, without involvement of the lung, with the uniportal video-assisted technique. The chest is entered through the fourth intercostal space, mid-axillary line. Dissection of the paratracheal space anteriorly, the tracheoesophageal groove posteriorly and the subcarinal space and division of the azygos arch are essential to mobilize the distal trachea and carina. Lateral dissection should be avoided beyond the points of division of the airway, as it may hinder the blood supply to the anastomosis. Any tension to the anastomosis should be relieved by release maneuvers. Ventilation is achieved through an endobronchial catheter, inserted into the left main bronchus through which a high-frequency jet ventilation catheter can be also inserted through it. The rationale of applying a minimally invasive technique for the conduction of tracheal and carinal resections, is to exploit its advantages, namely less pain, earlier mobilization and lower morbidity. Uniportal video-assisted resections of the distal trachea, carina and the main bronchi, are safe when conducted by experienced surgical and anesthetic teams.
