The investigators present a series of adults with severe acute respiratory distress syndrome (ARDS) who were treated with extracorporeal membrane oxygenation (ECMO) at a regional referral center. ⋯ ECMO provides support that prevents ventilator-induced lung injury while the lungs heal. The investigators present a series of 36 adults with refractory hypoxemic ARDS (ratio of partial pressure of oxygen to fraction of inspired oxygen <50) from 17 different facilities who, treated with ECMO at a single referral center, had a 60% survival rate.

The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) model and its Portsmouth modification (P-POSSUM) are used extensively to predict postoperative mortality and morbidity in general surgery. The aim of this study was to undertake the first systematic review of the predictive value of these models in patients undergoing pancreatic surgery. ⋯ POSSUM overpredicted postoperative morbidity in patients undergoing pancreatic surgery. Both POSSUM and P-POSSUM failed to offer significant predictive value for mortality in pancreatic surgery, and more data collection in large populations undergoing pancreatic surgery are needed.

Compression anastomosis ring device in colorectal anastomosis: a review of 1,180 patients.
The nickel-titanium compression anastomosis ring device (ColonRing, NiTi Surgical Solutions, Netanya, Israel) has been cleared by the Food and Drug Administration in 2006 to construct gastrointestinal anastomoses. We evaluated the anastomotic leak rate after end-to-end anastomosis using the ColonRing device. ⋯ The use of the ColonRing device is feasible and safe and could be considered an alternative technology for end-to-end colorectal anastomosis.

Previous observations suggest that intraoperative blood transfusion (IBT) is a risk factor for adverse postoperative outcomes. IBT alters immune function and may predispose to systemic inflammatory response syndrome (SIRS). ⋯ There is a significant association between IBT and the development of SIRS. IBT may induce SIRS, and reductions in IBT may decrease the incidence of postoperative SIRS.

Microvascular hyperpermeability that occurs in hemorrhagic shock and burn trauma is regulated by the apoptotic signaling pathway. We hypothesized that tumor necrosis factor-α (TNF-α)-related apoptosis-inducing ligand (TRAIL) would promote hyperpermeability directly or by interacting with other signaling pathways. ⋯ TRAIL-induced microvascular hyperpermeability is phosphatidylinositol 3-kinase (PI3K)-dependent and may be mediated by caspase-3 cleavage of the endothelial adherens junctional complex.
