Characterizing the burden of surgical disease has been defined as a priority research agenda in global surgery. Little is known about the epidemiology of inguinal hernia, a common easily treatable surgical condition, in resource-poor settings. Using data from the(More)
Surgical conditions represent a significant source of global disease burden. Little is known about the epidemiology of inguinal hernia in resource-poor settings.

OBJECTIVE Even in the setting of duplex ultrasound (DUS) surveillance, a significant number of lower extremity vein bypass grafts (LEVBGs) become occluded as a first event. We sought to identify factors that may contribute to these primary occlusions. METHODS This was a retrospective analysis of the Project of Ex Vivo Graft Engineering via Transfection(More)
