BACKGROUND Nonoperative management is the standard of care in hemodynamically stable patients with blunt splenic injury. However, a number of issues regarding the management of these patients are still unresolved. The aim of this study was to reach consensus among experts concerning optimal treatment and follow-up strategies. METHODS The Delphi method was(More)
BACKGROUND In recent years there has been increasing interest shown in the nonoperative management (NOM) of blunt traumatic injury. The growing use of NOM for blunt abdominal organ injury has been made possible because of the progress made in the quality and availability of the multidetector computed tomography (MDCT) scan and the development of minimally(More)
BACKGROUND Trauma systems have data registries in order to describe and evaluate (the quality of) trauma care. If results between centres and countries (benchmarking) are to be compared, data has to be accurate, reliable and complete. All trauma registries deal with incompleteness. A contributor to incompleteness of the data is failure to include patients(More)
Local formation of the sphingomyelin metabolite sphingosine-1-phosphate (S1P) within the vascular wall has been shown to modulate vascular reactivity. In this study we investigated whether sphingosine kinase, the enzyme responsible for S1P synthesis, plays a role in muscarinic receptor-mediated NO production and vascular relaxation in different blood vessel(More)
Splenic artery embolization (SAE) is increasingly being used as a nonoperative management strategy for patients with blunt splenic injury following trauma. The aim of this study was to assess the splenic function of patients who were embolized. A clinical study was performed, with splenic function assessed by examining the antibody response to(More)
BACKGROUND Debate continues about the optimal management strategy for patients with renal injury. PURPOSE To report the diagnostics and treatment applied in a level 1 trauma centre and to compare it to the recommendations of the European Association of Urology guidelines concerning blunt renal injury. METHODS The management of all patients with blunt(More)
BACKGROUND Timely intervention in patients with splenic injury is essential, since delay to treatment is associated with an increased risk of mortality. Transcatheter Arterial Embolisation (TAE) is increasingly used as an adjunct to non-operative management. The aim of this study was to report time intervals between admission to the trauma room and start of(More)
Non-operative management (NOM) is the standard of care in hemodynamically stable patients with blunt splenic injury after trauma. Splenic artery embolization (SAE) is reported to increase observation success rate. Studies demonstrating improved splenic salvage rates with SAE primarily compared SAE with historical controls. The aim of this study was to(More)
BACKGROUND The incidence of splenectomy after trauma is institutionally dependent and varies from 18% to as much as 40%. This is important because variation in management influences splenic salvage. The aim of this study was to investigate whether differences exist between Dutch level 1 trauma centers with respect to the treatment of these injuries, and if(More)
OBJECTIVE To investigate whether the routine performance of urinalysis in patients with a blunt trauma mechanism is still valuable. METHODS Consecutive patients aged ≥16 years, admitted to a Dutch Level 1 trauma centre between January 2008 and August 2011, were included in this retrospective cohort study. Results of urinalysis (erythrocytes per µL) were(More)
