911 How to Design a Low-Cost 3D Printed Laparoscopic Appendicectomy Simulation Model (LaApSi)?

A Low Cost Numerical Simulation of a Supersonic Wind-tunnel Design

In the present paper, a supersonic wind-tunnel is designed to maintain a flow with Mach number of 3 in a 30cm×30cm test section. An in-house CFD code is developed using the Roe scheme to simulate flow-field and detect location of normal shock in the supersonic wind-tunnel. In the Roe scheme, flow conditions at inner and outer sides of cell faces are determined using an upwind biased algorithm. ...

Laparoscopic Appendicectomy

Cost-minimisation analysis of laparoscopic and open appendicectomy.

OBJECTIVE To compare the direct and indirect costs of laparoscopic and open appendicectomy. DESIGN Randomised study. SETTING University hospital, Sweden. MAIN OUTCOME MEASURES Total costs for a defined period of time for each option. RESULTS 102 patients were randomised and 99 were included in the final analysis. All patients had completely recovered within two months of operation. Disp...

Evaluation of a low-cost, 3D-printed model for bronchoscopy training.

BACKGROUND Flexible bronchoscopy is a fundamental procedure in anaesthesia and critical care medicine. Although learning this procedure is a complex task, the use of simulation-based training provides significant advantages, such as enhanced patient safety. Access to bronchoscopy simulators may be limited in low-resource settings. We have developed a low-cost 3D-printed bronchoscopy training mo...

Clinical outcome and cost comparison between laparoscopic and open appendicectomy.

INTRODUCTION Local data comparing laparoscopic appendicectomy (LA) and open appendicectomy (OA) is lacking. We perform a cost and outcome comparison between LA and OA. MATERIALS AND METHODS A retrospective review of all appendicectomies performed for suspected appendicitis from July 2010 to December 2010 was conducted. Patient demographics, duration of surgery, complication rates, total cost ...
