Effect of transgastric natural orifice transluminal endoscopic surgery peritoneoscopy on abdominal organ microcirculation: an experimental controlled study.

Background And Aims: On-demand insufflation during endoscopic peritoneoscopy causes wide variations in intra-abdominal pressure. Its effects on splanchnic microcirculation may differ from those of steady intra-abdominal pressure, because pressure characteristics affect crucial intravascular hemodynamic forces--pressure and shear--adapting flow to local metabolic needs. Our aim was to assess the effect of natural orifice transluminal endoscopic surgery (NOTES) peritoneoscopy on splanchnic microcirculatory blood flow.

Transumbilical single-port sleeve gastrectomy: initial experience and comparative study.

Background: Sleeve gastrectomy is gaining relevance in the surgical armamentarium against obesity. The transumbilical single port has proved to be an attractive and safe alternative for a variety of minimally invasive abdominal surgeries. The purpose of this study is to evaluate the initial results of a group of patients operated by single-port sleeve gastrectomy compared with a group operated by conventional laparoscopic technique.

Which is the best technique for pancreaticoenteric reconstruction after pancreaticoduodenectomy? A critical analysis.

The definitive surgical management of periampullary tumors is a challenging endeavor. This article reviews the available data on the efficacy of various methods of pancreaticoenteric reconstruction designed for the prevention of pancreatic fistula (PF). A literature search of the Medline database was used to identify randomized controlled trials (RCTs) that compared pancreaticojejunostomy (PJ) with pancreaticogastrostomy (PG) after pancreaticoduodenectomy (PD).
