Filter by:Preoperative three-dimensional (3D) lung reconstructions can reduce intraoperative blood loss, conversion rate, and operation duration. Commercial products predominantly provide these 3D reconstructions, hence the aim of this study was to assess the usability and performance of preoperative 3D lung reconstructions created with open-source software.
With the increasing acceptance of routine computed tomography (CT) screenings, early-stage lung cancer detection is becoming more frequent. For ground glass opacity predominant early-stage lung cancer, segmentectomy can get the same oncological benefits as lobectomy. In addition, lung nodules that are highly suspected to be metastases can also be performed by segmentectomy to preserve more lung function. During the surgery, the rapid and precise identification of the intersegmental plane is one of the challenges. The improved inflation-deflation method is currently the most widely used method in clinical practice. According to the dispersion coefficient of the gas, the rapid diffusion properties of carbon dioxide would be expected to speed lung collapse and so facilitate surgery. The purpose of this study was to investigate the feasibility and safety of carbon dioxide on the appearance time of satisfactory and ideal planes during segmentectomy.
Three-dimensional (3D) simulation of pulmonary vessels and the space between the lesion and adjacent tissues is regarded improving the safety and accuracy of video-assisted thoracoscopic surgery (VATS) for segmentectomy for ground glass opacity (GGO) in lung. However, not every thoracic surgeon can handle the technique, in addition, the 3D reconstruction originate from the thin CT scan. Actually, the investigators found that, the reading and comprehension of the thin cross- section of CT can guide the accurate anatomic segmentectomy in most situations. The investigators designed a retrospective study to compare the reading of thin cross- section of CT with 3D reconstruction or without 3D reconstruction during the guidance of anatomic segmentectomy.
Anatomical variations of pulmonary vessel may cause serious problems during pulmonary segmentectomy. Three-dimensional （3D）computed tomography (CT) presents 3D images of pulmonary vessels and the tracheobronchial tree and may help operative planning. Retrospective studies have identified the importance of 3-dimensional CT in the field of pulmonary segmentectomy. And the aim of this study is to compare the usefulness of 3-dimensional CT with standard chest CT in preoperative planning of video-assisted segmentectomy.
This study will evaluate the impact of continuous, digital pulmonary air leak monitoring on the duration of pleural drainage after lung resection in patients with and without a pulmonary air leak on postoperative day 1. Patients undergoing pulmonary resection who fit the inclusion criteria will be identified pre-operatively. Patients within two groups (air leak and no air leak) will be randomized to receive either the analogue system or the digital system. Both systems are approved for use in hospitals by Health Canada. There will be 88 patients in each air leak group. Hypothesis: Continuous, quantitative monitoring of PAL following lung resection leads to an improvement in primary outcomes.
