Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging technique in trauma; however, the physiologic sequelae have not been well quantified. The objectives of this study were to characterize the burden of reperfusion and organ dysfunction of REBOA incurred during 30 or 90 min of class IV shock in a survivable porcine model of hemorrhage. ⋯ REBOA in shock improves MCAP and is associated with a greater lactate burden; however, this lactate burden returned to control levels within the study period. Ultimately, prolonged REBOA is a survivable and potentially life-saving intervention in the setting of hemorrhagic shock and cardiovascular collapse in the pig.

Portal vein embolization (PVE) is an effective procedure to increase the future remnant liver (FRL) before major hepatectomy. A controversial issue is that PVE may stimulate tumor growth and can be associated with poor prognosis after liver resection for colorectal liver metastases (CRLM). The aim of this study was to evaluate the impact of PVE on long-term survival following major hepatectomy for CRLM. ⋯ This study showed that PVE did not affect overall survival and specific liver-disease-free survival in patients undergoing right or right-extended hepatectomy for unilobar, right-sided CRLM.

Randomized Controlled Trial Multicenter Study
A prospective, randomized trial of Roux-en-Y reconstruction with isolated pancreatic drainage versus conventional loop reconstruction after pancreaticoduodenectomy.
Postoperative pancreatic fistula (POPF) is a major and serious complication after pancreaticoduodenectomy (PD). There have been no prospective randomized trials evaluating POPF rates in Roux-en-Y reconstruction (RYR) with isolated pancreatic drainage versus conventional loop reconstruction (CLR). The authors hypothesized that RYR decreases the incidence and severity of POPF in patients after PD. ⋯ These data do not support the hypothesis that RYR is associated with a lower incidence of POPF than is CLR. However, they do indicate that RYR may contribute to decreasing fistula severity, duration of stay, and hospital expense.

Irreversible electroporation (IRE) is a novel ablation technique that induces permanent membrane permeability and cell death. We are interested in ultrasound B-mode and elastography to monitor IRE ablation in the liver. ⋯ IRE ablation led to increased tissue stiffness that was detectable by elastography and indicative of cell death. Elastography may complement B-mode ultrasonography to monitor IRE ablation of the liver.

Initiating prehospital resuscitation with plasma in patients with trauma-associated hemorrhagic shock will result in more rapid and durable clot formation and, thus, the need for fewer packed cell infusions, less frequent use of cryoprecipitate, and more ventilator-free hospital days compared with those of patients randomized to standard crystalloid field resuscitation.
