BACKGROUND Interest in the training and evaluation of laparoscopic skills is extending beyond the realm of the operating room to the use of laparoscopic simulators. The purpose of this study was to develop a series of structured tasks to objectively measure laparoscopic skills. This model was then used to test for the effects of level of training and(More)
Surgery and other invasive therapies are complex interventions, the assessment of which is challenged by factors that depend on operator, team, and setting, such as learning curves, quality variations, and perception of equipoise. We propose recommendations for the assessment of surgery based on a five-stage description of the surgical development process.(More)
STUDY OBJECTIVE To study the efficacy of intestinal decontamination by oral nonabsorbable antibiotic agents to control a nosocomial outbreak of intestinal colonization and infection with multiresistant Enterobacteriaceae, and to examine its effects on endemic nosocomial infection rates. DESIGN A 10-week prospective incidence study (group 1), and then an(More)
Research on surgical interventions is associated with several methodological and practical challenges of which few, if any, apply only to surgery. However, surgical evaluation is especially demanding because many of these challenges coincide. In this report, the second of three on surgical innovation and evaluation, we discuss obstacles related to the study(More)
OBJECTIVE This study determined the association between proximal gastrointestinal (GI) colonization and the development of intensive care unit (ICU)-acquired infection and multiple organ failure (MOF) in a population of critically ill surgical patients. SUMMARY BACKGROUND DATA ICU-acquired infection in association with progressive organ system dysfunction(More)
Surgical innovation is an important part of surgical practice. Its assessment is complex because of idiosyncrasies related to surgical practice, but necessary so that introduction and adoption of surgical innovations can derive from evidence-based principles rather than trial and error. A regulatory framework is also desirable to protect patients against(More)
Laparoscopic cholecystectomy (LC) has gained wide acceptance for treatment of cholelithiasis in preference to open cholecystectomy, though it has not been formally compared with mini cholecystectomy (MC). We have compared these two techniques in a randomised trial. 70 patients with ultrasound-proven cholelithiasis were randomly allocated LC (38) or MC (32);(More)
Laparoscopic cholecystectomy (LC) has been performed increasingly in an outpatient setting. Conversion from LC to open cholecystectomy (OC) is sometimes required. To predict conversion to OC, a single institutional study of 1,676 consecutive patients in whom LC was attempted was performed. Factors evaluated were age, sex, history of acute cholecystitis,(More)
OBJECTIVE A 20-year follow-up was conducted on research into the implications of a lack of a delayed-type hypersensitivity (DTH) skin test response among surgical patients. SUMMARY BACKGROUND DATA The authors' original report showed that a failed DTH response was associated with increased hospital mortality, but the role of specific and nonspecific host(More)
