Comparative StudyBlood transfusion does not adversely affect survival after elective colon cancer resection: a propensity score analysis.
The aim of this study was to assess the putative impact of perioperative blood transfusions on overall survival in patients undergoing curative resection for stage III colon cancer by applying propensity scoring methods. ⋯ This study is the first propensity score-based analysis that provides evidence that poor oncological outcomes after curative colon cancer resection in patients receiving perioperative blood transfusions are due to the clinical circumstances that require the transfusions and are not due to the blood transfusions.

Comparative StudyComparison of two different transection techniques in liver surgery-an experimental study in a porcine model.
Postoperative morbidity and mortality after liver resection is closely related to the degree of intraoperative blood loss; the majority of which occurs during transection of the liver parenchyma. Many approaches and devices have therefore been developed to limit bleeding, but none has yet achieved perfect results up to now. The aim of this standardized chronic animal study was to compare the safety and efficacy of the LigaSure™ Vessel Sealing System (LVSS) with the stapler technique, which is one of the modern techniques for transecting the parenchyma in liver surgery. ⋯ In this standardized chronic animal study concerning transection of the parenchyma in liver surgery, LVSS seems not only to be safe, but also comparable with the stapler technique in terms of morbidity and mortality. Additionally, LVSS significantly reduces material costs. However, the transection time is significantly longer for LVSS than for the stapler resection technique.
