Radical esophagectomy is a highly invasive operation for esophageal cancer, and improved techniques are being sought to reduce the invasiveness of this procedure. We devised a method in which an assistant inserts their left hand into the thoracic cavity, and the operator inserts their left hand into the abdominal cavity through a small incision in the(More)
This study was designed to reexamine the healing process of expanded polytetrafluoroethylene (EPTFE) grafts with standard porosity (30μm) and high porosity (60μm) in portal vein replacement, and to evaluate the effect of an omentum wrap, which has certain functions that promote healing, on graft healing. These grafts, either wrapped by the omentum or not,(More)
This study was designed to examine the short-term performance of Gianturco stents placed in the venous system, in comparison with that of stents placed in the arterial system. Single-bodied modified Gianturco stents were surgically placed in six dogs (group 1), while in another six dogs, only exposure of the vessels was performed (group 2). Segments with an(More)
We examined the patency and healing of a highporosity expanded polytetrafluoroethylene (ePTFE) graft implanted as an interposition graft in the thoracic inferior vena cava (IVC) and wrapped in an omental pedicle flap. High-porosity ePTFE grafts of 60 μ fibril length, with an internal diameter of 10 mm and a length of 4 cm, were implanted in 12 mongrel dogs.(More)
The purpose of this study was to examine the short- and long-term performance of conventional polytetrafluoroethylene (PTFE) grafts for portal vein reconstruction. The grafts were placed as a portal vein replacement in 11 mongrel dogs. At 1 month and 6 months, the grafts were then retrieved and examined for patency, while also undergoing a pathological(More)
We previously reported that, in a short-term thoracic inferior vena cava (IVC) replacement, a highporosity expanded polytetrafluoroethylene (ePTFE) graft (fibril length 60μm) performed well without altering the short-term patency, and that the healing of the high-porosity ePTFE graft was accelerated by an omentum wrap. The purpose of this study was to(More)
