PURPOSE The purpose of the study was to evaluate unenhanced Magnetic Resonance Imaging (MRI) for the diagnosis of appendicitis or another surgery-requiring condition in an adult population scheduled for emergency appendectomy based on a clinical diagnosis of suspected acute appendicitis. MATERIALS AND METHODS The prospective study included 48 consecutive(More)
OBJECTIVE Laparoscopic surgery may offer advantages compared to open surgery, such as earlier mobilization, less pain and lower post-surgical morbidity. Surgical stress is thought to be associated with the postoperative immunological changes in the body as an impaired immune function, which may lead to an increased susceptibility to complications and(More)
OBJECTIVE Conventional colonoscopy (CC) is the gold standard for colonic examinations. However, patient acceptance is not high. Patient acceptance is influenced by several factors, notably anticipation and experience. This has led to the assumption that patient acceptance would be higher in non-invasive examinations such as MR/CT colonography (MRC/CTC) and(More)
BACKGROUND AND AIMS Self-expanding metallic stents (SEMS) have since 1991 established themselves as an option in the treatment of large bowel obstruction. The aim of this study was to evaluate the use of SEMS in management of acute colorectal obstructions at a Danish Surgical Gastroenterology center. MATERIAL AND METHODS Retrospective review of charts(More)
MR colonography (MRC) is a non-invasive method of examining the colon, but it is still only used in a few specialized centers on a daily basis. The purpose of this study was to evaluate the performance of MRC with improved fecal tagging vs. conventional colonoscopy (CC). Between March 2006 and February 2007, consecutive patients who received first-time(More)
MR colonography (MRC) is a promising method of examining the colon, but is limited to a few specialist centres. The purpose of this article was to describe the implementation of MRC with fecal tagging. Patients referred for conventional colonoscopy (CC) were offered MRC with fecal tagging before CC. Two days before MRC patients ingested an oral contrast(More)
OBJECTIVE Nurse Administered Propofol Sedation (NAPS) contributes to a deeper sedation of the patients, making them unable to respond to pain and an increased incidence of perforations has been speculated. The objective of this study was to evaluate the risk of perforations during colonoscopies performed with either NAPS or conventional sedation regimes. (More)
There have been worries of a potential negative effect of the fasting practice on surgeon's skills. We set out to examine the effect of fasting for a single surgeon during the fast and after the fast was broken. We examined the skills of the surgeon in a previously developed model for training in laparoscopic surgery. Foetor ex ore was also examined during(More)
Studies have shown that laparoscopic colectomy (LC) for inflammatory bowel disease (IBD) is just as safe as open colectomy. Some of the short-term advantages of laparoscopy are faster recovery, less pain, shorter hospital stay and fewer complications. The long-term advantages include superior cosmetic result, reduced intra abdominal adhesion formation, less(More)
RATIONALE AND OBJECTIVES Both magnetic resonance (MR) and computed tomographic (CT) colonography are useful for colon examination. With sensitivities close to those for conventional colonoscopy (CC) for polyps, colonography has been proposed as an alternative to diagnostic CC. MR colonography (MRC) with fecal tagging may be a method of gaining further(More)
