Esophageal carcinoma is one of the most common malignant tumor, a serious threat to human health. In the early and middle esophageal carcinoma patients, surgery is the only expected treatment to cure esophageal carcinoma. Traditional surgery of esophageal cancer needs thoracotomy and laparotomy, which has great trauma and high incidence of complications. So surgeons are looking for a minimally invasive surgical methods alternative to traditional esophagectomy. Video-mediastinoscopy is used to free middle and upper esophagus, as a minimally invasive surgical method, it is used in radical resection of esophageal cancer gradually. This article reviews the recent progress and the related research results in the application of mediastinoscopy in the radical resection of esophageal cancer. It is found that mediastinoscopy assisted the radical resection of esophageal cancer is a safe and feasible operation. It provides a feasible treatment option for early and middle stage esophageal cancer patients with pulmonary insufficiency who can not be resected by thoracoscopy.
ObjectiveTo explore the value of modified method for intratumoral injection of thrombin in the treatment of iatrogenic pseudoaneurysms.MethodsClinical data of 28 patients with iatrogenic pseudoaneurysms after interventional treatment in our hospital from October 2012 to June 2018 were retrospectively analyzed. Twenty-one cases were treated with ultrasound-guided thrombin injection for pseudoaneurysms (Ultrasound group), and seven cases were treated with DSA-mediated balloon occlusion and thrombin injection for pseudoaneurysms (DSA group). The patients were followed-up at 1 day, 1 month and 3 monthS after operation.ResultsThe total success rates of the two groups were 100%. There was no treatment-related complications in the two groups. There was no recurrence after 1–3 months of treatment.ConclusionsIntratumoral injection of thrombin can be used for the treatment of iatrogenic pseudoaneurysm. The effect of the improved treatment is more significant. These two methods can be used as the best way to treat iatrogenic pseudoaneurysm with different neck diameters.
ObjectiveTo investigate the clinical value of 3D CT combined with CT-guided Hookwire for localizing small pulmonary nodules in thoracoscopic pulmonary segmentectomy.MethodsFrom December 2017 to February 2019, 39 patients received thoracoscopic pulmonary segmentectomy in our hospital, including 14 males and 25 females with a mean age of 51.33±11.17 years. Before operation, we used Mimics Medical 20.0 to re-establish the anatomy of lung and locate the small pulmonary nodules with Hookwire guided by CT. Based on the position of Hookwire needle, 3D CT images and simulated surgical methods, thoracoscopic pulmonary segmentectomy was performed accurately.ResultsThe surgery was successfully completed in 39 patients without a transfer to open procedure. The mean operation time, mean intraoperative blood loss, mean postoperative hospital stay, mean thoracic tube drainage time were 148.97±28.56 min, 27.95±17.57 mL, 6.95±1.68 d, 4.21±1.95 d, respectively. Postoperative complications occurred in 5 patients (12.82%), including atrial fibrillation in 1, pulmonary infection in 1, chylothorax in 1, intrathoracic hemorrhage in 1 and pneumothorax in 1. All actual surgical margins were larger than 3.0 cm.ConclusionThe application of preoperative 3D CT combined with CT-guided Hookwire to localize small pulmonary nodules is helpful for accurate anatomical segmental resection of the lung, making the operation safe .
