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.
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.
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.
Project description:Posterior basal (S10) segmentectomy is one of the most challenging (and uncommon) types of pulmonary segmentectomy. Here, we present two key tips for facilitating a uniportal operation. The first is a full understanding of the relative locations of the pulmonary vessels and bronchi (as revealed by preoperative three-dimensional computed tomography/broncho-angiography), and the other is the use of "suction-guided stapling" to dissect and divide the peripheral pulmonary vessels and bronchi. We describe the successful postoperative course of a patient who was so treated.
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.
