Objective: To identify risk factors for failure of conservative treatment for acute cholecystitis and thus identify earlier patients who will require percutaneous drainage.Summary Background: Current treatment options for acute calculus cholecystitis include either early cholecystectomy, or conservative treatment consisting of intra-venous antibiotics and an interval cholecystectomy several weeks later. Percutaneous drainage of the gallbladder is […]
Objective: Acute paraesophageal hernia is a surgical emergency presenting with chest pain, abdominal pain, dysphagia, nausea and vomiting, retching or significant anemia. This can be due to gastric volvulus, incarceration, strangulation, severe bleeding or perforation. Traditionally this is treated with an open surgery. The purpose of this study is to evaluate the outcome of laparoscopic […]
Objective: Hybrid simulators provide objective metrics for laparoscopic task performance. The aim of this study was to evaluate the correlation between hybrid simulator-generated metrics and content valid outcome measures.Methods and Procedures: Residents underwent training with a previously validated 5-task simulation model (5-TSM). Tasks included: clip/divide vessel, excise lesion, loop appendectomy, mesh placement with tacks, and […]
INTRODUCTIONIntestinal ischemia is difficult to diagnose in a critically ill patient. Natural orifice transluminal peritoneoscopy may provide us with a valuable diagnostic tool that can be performed at the bedside with minimal equipment requirements with a potential for a high sensitivity in detecting ischemic bowel. The aim of this study is to develop a bowel […]
Introduction: We previously reported successful transvaginal NOTES cholecystectomy in a porcine model using a Magnetic Anchoring and Guidance System (MAGS). The purpose of this study was to further optimize MAGS instruments for this procedure.Methods: Preliminary in-vivo testing (n=1) and complete non-survival procedures (n=3, 33-34kg) were performed in pigs. Through a vaginotomy created under direct vision, […]
