PURPOSE Clinical practice guidelines of many professional societies call for routine staging chest x-rays (SCXR) for all patients with invasive cancer. Given the estimated 157,000 patients annually for whom this recommendation pertains, this screening examination represents a considerable health care expenditure. If it were shown that SCXR rarely changed(More)
BACKGROUND Incisional hernia and fascial dehiscence are associated with significant postoperative morbidity. Electrosurgical devices using pulsed radiofrequency energy and a novel electrode design markedly reduce thermal injury during cutting and coagulation while maintaining equal surgical performance. In this study, we examine fascial healing dynamics in(More)
PURPOSE To compare the durability of thoracic endovascular aortic repair (TEVAR) in two similar clinical trials that used early- and later-generation stent grafts. MATERIALS AND METHODS Secondary procedures from the prospective, nonrandomized, multicenter, clinical trial databases of the test arm of the VALOR and VALOR II trials were analyzed at 3 years.(More)
BACKGROUND The PEAK PlasmaBlade is a new electrosurgical device that uses pulsed radiofrequency to generate a plasma-mediated discharge along the exposed rim of an insulated blade, creating an effective cutting edge while the blade stays near body temperature. METHODS Full-thickness incisions were made on the dorsums of pigs with the PlasmaBlade, a(More)
