BACKGROUND Technical performance has traditionally been assessed subjectively within the operating theater, with few successful attempts at objective analysis. The Imperial College Surgical Assessment Device (ICSAD) has already been shown to be a valid quantitative measure of dexterity in laparoscopic surgical simulation. We describe its application to the(More)
AIM To demonstrate face and construct validity of a computer based flexible sigmoidoscopy trainer. METHODS The PreOp (Immersion Medical, USA) system is a virtual reality based flexible sigmoidoscopy simulator. The system records several performance parameters, such as percentage of colonic mucosa visualized, time taken, and pathlength of endoscope travel.(More)
BACKGROUND Enterocutaneous fistula associated with type 2 intestinal failure is a challenging condition that involves a multidisciplinary approach to management. It is suggested that complex cases should only be managed in select national centers in the United Kingdom. METHODS Over an 18-month period, we prospectively studied all patients referred to us(More)
Anal carcinoma is an important but rare condition, managed in specialist centres. Both endoanal ultrasound and magnetic resonance imaging (MRI) can be used in the locoregional staging and follow-up of patients with anal cancer, and both may assist in treatment planning and prognosis. Recent guidelines published by the European Society for Medical Oncology(More)
BACKGROUND "Massed" and "distributed" practice are important concepts in the acquisition of fine motor skills, and may be important in training in procedural skills. METHODS A total of 41 novice subjects were recruited and randomized to three groups to receive training on the MIST VR surgical trainer. There were 14 subjects in each of groups A and B and(More)
BACKGROUND Recent attempts to gain a more objective measure of surgical technical skill include the use of structured checklists and motion analysis of surgeons' hand movements. We aim to show whether a correlation exists between these two methods of assessment. METHODS Fifty subjects were recruited from four experience groups in general surgery, ranging(More)
BACKGROUND Recent attention has been directed at developing quantitative assessments of surgical skill. This study aims to demonstrate whether objectively measuring differences in manual dexterity has an impact on a simulated surgical procedure. METHODS Six general surgical trainees performed 5 polytetrafluoroethylene graft to artery anastomoses on a(More)
BACKGROUND Technical skills assessments are being increasingly used in surgical residency programs, with the objectivity and validity of several techniques well established. However, many of these methods are labor and time intensive, limiting their feasibility. This study aims to compare more efficient techniques of skills appraisals with an established(More)
BACKGROUND Attempts at assessing surgical proficiency have generally used laboratory simulation to evaluate skill. The aim of this study was to compare technical ability as measured on a bench simulation with actual operative performance. STUDY DESIGN Twenty-two general surgeons and trainees were recruited: consultants (n = 4), specialist registrars (n =(More)
INTRODUCTION Electromagnetic motion analysis is a promising method of assessing surgical skill in a skills-laboratory setting. There is a very strong correlation between movement and time data, and this study was conducted to determine whether this relationship is fixed, or whether it can vary. METHODS : After a pilot study, four subjects were recruited.(More)
