BACKGROUND This study was undertaken to investigate operating room performance of surgical residents, after participating in the Eindhoven virtual reality laparoscopic cholecystectomy training course. This course is the first formal surgical resident trainings course, using a variety of complementary virtual reality (VR) skills training simulation in order(More)
OBJECTIVE To assess the effectiveness of bioresorbable Seprafilm membrane in preventing abdominal adhesions in a prospective clinical randomized multicenter trial. SUMMARY BACKGROUND DATA Adhesions occur frequently after abdominal operations and are a common cause of bowel obstruction, chronic abdominal pain, and infertility. To reduce the formation of(More)
BACKGROUND Port-site metastases after laparoscopic procedures in patients with digestive malignancies have evoked concern. The pathogenesis of port-site metastases remains unclear. Two experiments in rats were performed to determine the impact of both tissue trauma and leakage of CO2 along trocars (chimney effect) in the development of port-site metastases.(More)
The primary goal of endovascular treatment of abdominal aortic aneurysms (AAA) is prevention of death from rupture. Even in the absence of an endoleak, the AAA may continue to enlarge. The pathogenesis of this phenomenon remains unclear. Therefore, surveillance after endovascular AAA treatment must include regular evaluation of aneurysm size, or even(More)
BACKGROUND The oncologic consequences of intraperitoneal carbon dioxide (CO2) insufflation during the laparoscopic resection of cancer are under debate. The effect of other insufflating gases or gasless laparoscopy on cancer requires study. OBJECTIVE To study body weight and tumor growth in rats after CO2 pneumoperitoneum, air pneumoperitoneum, and(More)
PURPOSE To evaluate endoscopic fenestration as a treatment option for growing aneurysm due to a type II endoleak or endotension after endovascular aneurysm repair (EVAR). METHODS Eight patients (7 men; median age 69 years, range 55-79) who underwent "successful" EVAR were diagnosed with a growing aneurysm due to a type II endoleak (n=4) or endotension(More)
Many apparent differences exist in aetiology, genetics, anatomy and treatment response between colon cancer (CC) and rectal cancer (RC). This study examines the differences in patient characteristics, prevalence of complications and their effect on short-term survival, long-term survival and the rate of recurrence between RC and CC. For all stage II–III CC(More)
BACKGROUND The role of laparoscopic surgery in the treatment of colorectal disease is still controversial. To assess the metabolic consequences of laparoscopic and open bowel surgery, we studied serum levels of insulin-like growth factor 1 (IGF-1), an anabolic and mitogeneic peptide, in rats. MATERIALS AND METHODS In experiment 1, the serum IGF-1 levels(More)
BACKGROUND AND OBJECTIVES The objective of this study was to explore the association among adverse events, body mass index (BMI), and hospital costs after colorectal cancer surgery in a country with an intermediate BMI distribution. METHODS All colorectal cancer procedures in 29 Dutch hospitals listed in a 2010-2012 population-based database and with a(More)
