For severe malignant airway stenosis, there are several types of commercially available airway stents, and each has its own advantages and disadvantages. We herein describe the safety and efficacy of combination stenting with silicone and metallic stents for patients with extended malignant airway stenosis. Seven patients with malignant airway stenosis were treated via combination stenting with a silicone stent and a metallic stent for extended airway stenosis from the central to peripheral airways. Five patients were diagnosed with advanced esophageal cancer, two of whom had tracheoesophageal fistulas...

PURPOSE: Complete mesocolic excision (CME) with central vascular ligation (CVL) has been widely accepted as a surgical treatment for right-sided colon cancer. Single-site laparoscopic colectomy (SLC) is associated with reduced pain and improved cosmesis, in comparison to the multi-site laparoscopic colectomy (MCL). Although the feasibility of CME + CVL under MCL has been reported, SLC for right-sided colon cancer is generally challenging. The purpose of this study is to demonstrate our efforts to standardize the SLC for right-sided colon cancer...
