The development of acute renal failure and myocardial infarction (MI) following colectomy prolongs recovery and is associated with worse outcomes. The purpose of this study is to identify perioperative factors that predispose patients to an adverse cardiac or renal complication. ⋯ This study demonstrates that several potentially modifiable preoperative and intraoperative factors exist that predispose patients to postoperative cardiac and renal dysfunction in the absence of major surgical complications.

Obstructive jaundice is associated with bacterial translocation and inflammatory cytokine induction. It is unknown if toll-like receptors (TLRs) and their upstream molecule high mobility group box-1 (HMGB1) are involved in the pathogenetic mechanism and if glucocorticoid is effective in modulating the process. ⋯ The results indicate that obstructive jaundice may induce hepatic HMGB1 expression with activation of TLR4 and a number of downstream signaling molecules, which can be reversed by glucocorticoid administration.

Sepsis models are frequently based on induction of peritonitis, with cecal ligation and puncture reflecting the prototypical model. However, there is an ongoing discussion about the limitations of these models due to their variability in progression and outcome. Since standardization is a cornerstone of experimental models, we aimed to develop a reliable and reproducible procedure for induction of peritonitis. ⋯ This model reflects many features of human sepsis. Application of an infectious focus that is both quantitatively and qualitatively defined assures high reproducibility. Moreover, the procedure is simple and can be easily standardized.
