The cervico-ocular reflex (COR) is an ocular stabilization reflex that is elicited by rotation of the neck. It works in conjunction with the vestibulo-ocular reflex (VOR) and the optokinetic reflex (OKR) in order to prevent visual slip over the retina due to self-motion. The gains of the VOR and OKR are known to decrease with age. We have investigated(More)
BACKGROUND Incisional hernia is a frequent complication of midline laparotomy and is associated with high morbidity, decreased quality of life, and high costs. We aimed to compare the large bites suture technique with the small bites technique for fascial closure of midline laparotomy incisions. METHODS We did this prospective, multicentre, double-blind,(More)
This study aims to increase knowledge of colorectal anastomotic leakage by performing an incidence study and risk factor analysis with new potential risk factors in a Dutch tertiary referral center. All patients whom received a primary colorectal anastomosis between 1997 and 2007 were selected by means of operation codes. Patient records were studied for(More)
BACKGROUND Sustained increased intra-abdominal pressure (IAP) has negative effects. Noninvasive IAP measurement could be beneficial to improve monitoring of patients at risk and in whom IAP measurements might be unreliable. We assessed the relation between IAP and abdominal wall tension (AWT) in vitro and in vivo. MATERIALS AND METHODS The abdomens of 14(More)
BACKGROUND Incisional hernia is one of the most frequent postoperative complications after abdominal surgery. Patients with an abdominal aortic aneurysm and patients with a body mass index of 27 or higher have an increased risk to develop incisional hernia. Primary mesh augmentation is a method in which the abdominal wall is strengthened to reduce(More)
Whiplash-associated disorders (WAD) are a major problem in the Western world, which put a formidable financial burden on modern society and which evoke an emerging debate on the true nature of their origin. To date there is no generally accepted test that allows us to diagnose WAD objectively. Because whiplash injury causes dysfunction of proprioception in(More)
We assessed syndesmotic set screw strength and fixation capacity during cyclical testing in a cadaver model simulating protected weight bearing. Sixteen fresh frozen legs with artificial syndesmotic injuries and a syndesmotic set screw made of stainless steel or titanium, inserted through three or four cortices, were axially loaded with 800 N for 225,000(More)
BACKGROUND Peroperative identification and subsequent division or preservation of the inguinal nerves during open hernia repair may influence the incidence of chronic postoperative pain. METHODS A systematic literature review was performed to identify studies investigating the influence of different types of nerve management. RESULTS Based on three(More)
BACKGROUND Anastomotic leakage is the major complication after colorectal surgery. To date, animal experiments concerning colorectal anastomosis focus on anastomotic healing instead of anastomotic leakage. This study aims to develop a new experimental model for colorectal anastomotic leakage. METHODS A control group, receiving an anastomosis with 12(More)
Over the past 10 years, several minimally invasive procedures for thyroid surgery have been developed. Because of extensive dissection in the thoracic and neck region, the name “minimal-invasive” is misleading. The aim of this study was to define a new trans-oral access to the cervical spaces especially to the thyroid on the basis of natural orifice(More)
