Irreversible electroporation of the liver: is there a safe limit to the ablation volume?

Sánchez-Velázquez, Patricia; Castellví, Quim; Villanueva, A; Quesada, Rita; Pañella, C.; Cáceres, Marta; Dorcaratto, Dimitri; Andaluz, Anna; Moll, X.; Trujillo Guillen, Macarena; Burdío Pinilla, José Miguel; Berjano Zanón, Enrique; Grande, Luis; Ivorra, A.; Burdío Pinilla, Fernando (Nature Publishing Group, 2016-04-01)

Irreversible electroporation is a fast-growing liver ablation technique. Although safety has been well documented in small ablations, our aim is to assess its safety and feasibility when a large portion of liver is ...
Is occlusion of the main pancreatic duct by thermal ablation really safe? A surgical innovation assessed according to IDEAL recommendations
