Role of Endoscopic Ultrasound Elastography in Diagnosis of Gastrointestinal Subepithelial and Mediastinal Lesions

The aim of this study is to evaluate the role of endoscopic ultrasound (EUS) in the diagnosis of mediastinal and gastrointestinal subepithelial lesions. The study also aims to assess the diagnostic accuracy of endoscopic ultrasound (EUS) elastography in differentiating benign from malignant mediastinal and gastrointestinal subepithelial lesions.

Subxiphoid VATS for Giant Mediastinal Teratoma

For giant mediastinal teratomas, the only treatment option available is usually open-chest surgery, which causes significant trauma, leads to obvious postoperative pain and may result in long-term complications such as chest wall deformity. Currently, we have developed a new treatment method. We use a double retractor system to pull the upper and lower ends of the sternum, lifting it to obtain sufficient surgical space behind the sternum. This enables us to perform minimally invasive tumor resection through the subxiphoid approach with thoracoscopy. The advantages of this method include reduced surgical trauma and postoperative pain, shortened hospital stay, and improved cosmetic effect
