Enhanced recovery after surgery (ERAS) or fast-track surgery is a perioperative and postoperative care concept initiated in the early 1990s aiming to reduce the length of hospital stays following elective abdominal surgery. Twenty treatment items defined in the Consensus Guidelines established in 2009 were included in this concept. The success of ERAS depends highly on multidisciplinary teamwork and patient compliance. Several ERAS items and their impact on perioperative and postoperative care have recently been discussed. In this connection, translational research topics triggered increasing interest in ERAS and new impulses aimed at improving the ERAS concept. We thus reviewed the surgical literature to highlight the role of translational research items in ERAS. ⋯ The Consensus Guidelines for ERAS are subject to the constant evolution of treatment strategies and implementation of translational research findings. Improvement of the compliance with ERAS protocols in surgical clinics and updating of ERAS items taking into account recent findings in translational research may improve the outcomes of ERAS but remain a long-term challenge in surgery for the next years.

Omni-stat®, a polysaccharide made by de-acetylation of chitin, is currently in use as a battlefield topical haemostat. This experimental study undertakes the first evaluation of Omni-stat in an in vivo porcine hepatectomy and liver trauma model. ⋯ Omni-stat is an effective haemostat in experimental in vivo porcine liver resection and liver trauma. Further evaluation is required to assess its physiological absorption profile in man and its comparative efficacy against commercially established agents.

Retrospective studies have drawn attention to possible detrimental effects of non-steroidal anti-inflammatory drugs (NSAIDs) on the anastomotic leakage rate after colorectal resection. In this study, we examined the effects of the NSAID diclofenac on the breaking strength of an experimental colonic anastomosis and a skin incision as well as subcutaneous collagen accumulation. ⋯ Postoperative diclofenac treatment significantly inhibited collagen deposition in subcutaneous granulation tissue. Anastomotic strength and skin wound strength were not significantly affected. The ePTFE model is suitable for assessing the effect of various drugs on collagen formation and thus on wound healing.

The patient's individual anemia tolerance is pivotal when blood transfusions become necessary, but are not feasible for some reason. To date, the effects of neuromuscular blockade (NMB) on anemia tolerance have not been investigated. ⋯ Deep NMB with rocuronium bromide increases the tolerance of acute normovolemic anemia. The underlying mechanism most likely involves a reduction of skeletal muscular VO(2). During acellular treatment of an acute blood loss, NMB might play an adjuvant role in situations where profound stages of normovolemic anemia have to be tolerated (e.g. bridging an unexpected blood loss until blood products become available for transfusion).

The use of intraoperative blood salvage autotransfusion (IBSA) during surgical approaches may contribute to tumour cell dissemination. Therefore, IBSA should be avoided in cases of malignancy. However, the risks of IBSA might be acceptable in liver transplantation (LT) for selected small hepatocellular carcinoma (HCC). ⋯ Our results indicate that IBSA does not modify the risk of HCC recurrence. Therefore, in highly selected HCC patients undergoing LT, the use of IBSA appears to be justified.
