Prophylactic application of modified vacuum-assisted closure therapy in Ivor Lewis esophagectomy: Preliminary results

Figure 1 Schematic illustration of the modified vacuum-assisted closure system. The device consists of a 10-Fr feeding tube inserted through an 18-Fr nasogastric tube. Multiple side holes were created along the distal 3 cm of the feeding tube to allow continuous negative-pressure drainage at the anastomotic site.
