Our objective was to obtain national data of the estimated prevalence, sociodemographic relationships, and health impact of persons with functional gastrointestinal disorders. We surveyed a stratified probability random sample of U.S householders selected from a data base of a national market firm (National Family Opinion, Inc.). Questions were asked about(More)
BACKGROUND Accurate population-based data are needed on the incidence of esophageal adenocarcinoma and high-grade dysplasia among patients with Barrett's esophagus. METHODS We conducted a nationwide, population-based, cohort study involving all patients with Barrett's esophagus in Denmark during the period from 1992 through 2009, using data from the(More)
BACKGROUND This study examined the impact of virtual reality (VR) surgical simulation on improvement of psychomotor skills relevant to the performance of laparoscopic cholecystectomy. METHODS Sixteen surgical trainees performed a laparoscopic cholecystectomy on patients in the operating room (OR). The participants were then randomized to receive VR(More)
BACKGROUND Introduction of the laparoscopic surgical technique has reduced hospital stay after colonic resection from about 8-10 to 4-6 days. In most studies, however, specific attention has not been paid to changes in perioperative protocols required to maximize the advantages of the minimally invasive procedure. In the present study the laparoscopic(More)
OBJECTIVE To develop an evidence-based virtual reality laparoscopic training curriculum for novice laparoscopic surgeons to achieve a proficient level of skill prior to participating in live cases. SUMMARY BACKGROUND DATA Technical skills for laparoscopic surgery must be acquired within a competency-based curriculum that begins in the surgical skills(More)
BACKGROUND The study was carried out to analyze the learning rate for laparoscopic skills on a virtual reality training system and to establish whether the simulator was able to differentiate between surgeons with different laparoscopic experience. METHODS Forty-one surgeons were divided into three groups according to their experience in laparoscopic(More)
BACKGROUND The risk of bile duct injury in laparoscopic cholecystectomy has been a concern since the procedure became part of the surgical armamentarium. Our study assesses the incidence, types, and treatment for laparoscopic bile duct injury. STUDY DESIGN Prospective case registration in a national database with participation by all departments of(More)
BACKGROUND Many patients with gastro-oesophageal reflux disease (GERD) are hypersensitive to heat and acid and may respond insufficiently to standard treatment. Antagonists of the heat and acid receptor 'transient receptor potential vanilloid 1'(TRPV1) are a potential drug class for GERD treatment. AIM To investigate the effect of a TRPV1 antagonist(More)
BACKGROUND & AIMS In various chronic pain conditions cortical reorganization seems to play a role in the manifestations. The aim of this study was to investigate cortical reorganization in patients with pain caused by chronic pancreatitis. METHODS Twelve healthy subjects and 10 patients with chronic pancreatitis were included. The esophagus, stomach, and(More)
Background: The impact of gender and hand dominance on operative performance may be a subject of prejudice among surgeons, reportedly leading to discrimination and lack of professional promotion. However, very little objective evidence is available yet on the matter. This study was conducted to identify factors that influence surgeons’ performance, as(More)
