Retroperitoneal vascular injury remains one of the most frequent causes of death following abdominal trauma. A risk analysis of the association between potential outcome predictors and mortality following abdominal aorta and inferior vena cava injuries was performed. ⋯ Despite advances in transport and resuscitation, mortality of aortic and vena cava injuries remains unchanged. Shock on admission, bleeding without retroperitoneal tamponade, acidosis, and the suprarenal location each play a significant role in mortality. Immediate identification associated with a rapid surgical approach are the only factors that may improve survival of such devastating injuries.

Interleukin-6 (IL-6), interleukin-8 (IL-8), and adhesion molecules have been implicated as mediators in neutrophil (PMN) and endothelial cell (EC) interactions leading to postinjury multiple organ failure (MOF). Our hypothesis was that circulating levels of IL-6, IL-8, and soluble intercellular adhesion molecule-1 (sICAM-1) would discriminate patients at risk for postinjury MOF. ⋯ Interleukin-6 and IL-8 are elevated early after trauma and discriminate patients who will develop MOF. Late elevation of sICAM-1 likely results from PMN cytotoxicity leading to EC injury or inflammation.

Comparative Study
A cost-minimization analysis of laparoscopic cholecystectomy versus open cholecystectomy.
Earlier economic analyses have evaluated charges but not costs, and have not considered the cost of production losses associated with open and laparoscopic cholecystectomy. This study attempted to accomplish an economic evaluation of open versus laparoscopic cholecystectomy from the point of view of society. ⋯ From the point of view of society, laparoscopic cholecystectomy was a cost-saving strategy if at least 68 patients were operated on yearly. However, with regard to hospital costs, open cholecystectomy was less expensive than laparoscopic cholecystectomy.

Randomized Controlled Trial Clinical Trial
Effect of patient position upon success in placing central venous catheters.
There is little consensus regarding the most efficient or the safest method by which to place a central venous catheter (CVC). ⋯ The bump position improves the likelihood of successful central venous catheter placement. No more than three needle passes ought to be attempted.

Intraoperative inadvertent perforation of the rectum is a potentially avoidable complication of abdominoperineal resection (APR). Although widely thought to be detrimental, the impact of inadvertent perforation on outcome has not been conclusively determined, especially after controlling for potential confounding variables. The objective of this study was to determine if inadvertent perforation of the rectum during APR for rectal cancer is an independent risk factor for the adverse outcomes of local recurrence and/or death. ⋯ Inadvertent perforation of the rectum during APR is associated with increased local recurrence and decreased 5-year survival. The detrimental implications of inadvertent perforation during APR mandates meticulous avoidance.
