A phase II study of endoscopic submucosal dissection for superficial esophageal neoplasms (KDOG 0901).
Most previous studies of endoscopic submucosal dissection (ESD) for superficial esophageal neoplasms were retrospective; prospective studies are scant. ⋯ UMIN000002047.).

US-guided application of Nd:YAG laser in porcine pancreatic tissue: an ex vivo study and numerical simulation.
Laser ablation (LA) with a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser is a minimally invasive approach able to achieve a high rate of complete tissue necrosis. In a previous study we described the feasibility of EUS-guided Nd:YAG pancreas LA performed in vivo in a porcine model. ⋯ Volumes recorded suggest that the best laser OP could be the lowest one to obtain similar Va with smaller Vc in order to avoid the risk of thermal injury to the surrounding tissue. The good agreement between the two models demonstrates the prediction capability of the theoretical model on laser-induced ablation volume in an ex vivo animal model and supports its potential use for estimating the ablation size at different laser OPs.
