THE EFFECT OF ILEOCECAL VALVE REMOVAL IN A MODEL OF SHORT BOWEL SYNDROME.

Background: Short bowel syndrome is a harmful condition that needs experimental research.

Aim: To assess the impact of the ileocecal valve removal in a model of short bowel syndrome, in order to investigate the evolution of the colon under this circumstance.

Method: Fifteen Wistar rats were equitable divided into: Control (Sham), Group I (70% enterectomy preserving ileocecal valve) and Group II (70% enterectomy excluding ileocecal valve).

Liver Autotransplantation in Pigs without Venovenous Bypass: A Simplified Model using a Supraceliac Aorta Cross-Clamping Maneuver.

Background: The pig is an essential model for liver transplantation research and training. However, it develops hemodynamic instability during the anhepatic phase, requiring a short anhepatic phase or an extracorporeal circulation not appropriate for training purposes because it increases the risk of intraoperative complications. In this article we describe an economical and reproductive experimental model for training surgeon fellows in liver transplantation, without veno-venous bypass, using a supraceliac aortic cross-clamping maneuver.
