Postoperative chylothorax is a rare but potentially life-threatening complication. Conservative treatment is usually unsuccessful in patients with high-output chylothorax, for whom early surgical thoracic duct ligation has been advocated to minimize morbidity and mortality. This report describes left uniportal thoracoscopic closure of persistent high-output chylothorax through Poirier's triangle in a patient undergoing thoracoscopic thymectomy. After resection of pleural adhesions, the mediastinal pleura was resected at the level of the aortic arch, left subclavian artery, and vertebral column, the anatomic limits of Poirier's triangle. The thoracic duct was then isolated from the esophagus and successfully clipped along its path., (Copyright © 2019 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

We describe a new video-assisted technique for the management of a giant midesophageal diverticulum using a single 5-cm port. It maintained the same principles of the traditional open technique as diverticulectomy, myotomy, and fundoplication. The better visualization of the main esophageal body, diverticulum, and esophagogastric junction and the better alignment of the stapler cartridge to the longitudinal axis of the esophagus are all technical factors supporting our procedure. Heavily calcified mediastinal lymph nodes and diffuse pleural adhesions are the main contraindications. However, future experiences are needed before this technique can be recommended as acceptable treatment., (Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc.
