Background: Deferring the repair of a ventral hernia found at the time of an antecolic laparoscopic gastric bypass (LGB) increases the incidence of bowel obstruction. However, the optimal repair technique has not been established. The use of prosthetic mesh has been shown to decrease the recurrence of ventral hernias compared to primary closure, yet the […]
Aims: To compare energy utilisation and dissecting efficiencies of Ethicon® and LOTUS® ultrasonic surgical instruments.Methods: 1. Calorimetry experiments were performed to compare thermal energy produced by ultrasonic surgical devices adopting longitudinal (Ethicon Harmonic Scalpel®; EHS) and torsional (Laparoscopic Operation by Torsional UltraSound®; LOTUS) vibration modes, using differently shaped waveguide tips.2. An ex-vivo bench model was […]
Biliary surgery can often be very complex with difficult access issues, small structures to be manipulated and sutured and close proximity to major vessels. Additionally, biliary surgery is often reoperative. All of these issues have the potential to be aided by the use of technology which provides three-dimensional vision, excellent illumination and access, with steady […]
Objective: This is a study to determine the efficacy and feasibility of videolaryngoscopy as a training tool for emergent endotracheal intubations by surgical residents in the surgical intensive care unit (SICU). Methods: Over a fifteen month period ending December 2007, SICU patients underwent emergent endotracheal intubation using videolaryngoscopy. All residents underwent a thirty minute tutorial […]
Background: This paper presents precise estimates of nosocomial infection risks associated with laparoscopic as compared to open surgery in three procedures: cholecystectomy, appendectomy, and hysterectomy.Methods: A retrospective analysis was performed on 11,662 admissions from 22 hospitals that have a nosocomial infection monitoring system. The Nosocomial Infection Marker (NIM, patent-pending) was used to identify nosocomial infections […]
