Over the past decades, minimally invasive surgery has undergone continuous development due to the demand for scarless results, with laparo-endoscopic single-site (LESS) surgery constituting one of today’s most favored alternatives. In this study, we aim to assess the relative technical difficulty and performance benefits of dynamic articulating and pre-bent(More)
BACKGROUND This study analyzes the problems and consequences associated with prolonged use of laparoscopic instruments (dissector and needle holder) and equipments. METHODS A total of 390 questionnaires were sent to the laparoscopic surgeons of the Spanish Health System. Questions were structured on the basis of 4 categories: demographics, assessment of(More)
OBJECTIVE To explore the feasibility, safety, and short-term results of potassium-titanyl-phosphate (KTP) laser laparoscopic partial nephrectomy (KTP-LPN) vs conventional laparoscopic partial nephrectomy (C-LPN). MATERIALS AND METHODS Thirty large white female pigs were randomized to KTP-LPN or C-LPN. Laparoscopic radical right nephrectomy was performed,(More)
The aim of the present study was to assess the content and construct validity of the Canine Laparoscopic Simulator (CLS). Forty-two veterinarians were assigned to experienced (n=12), control (n=15), and training (n=15) groups, which were assessed while performing four laparoscopic tasks on the CLS. The initial and final assessments of all tasks were(More)
PURPOSE We present our experience in the design and development of a training program in laparoscopic radical prostatectomy (LRP), and the validation of the first steps of the program by objective measurement of the attendants' skills improvement and subjective evaluation of its contents. MATERIALS AND METHODS Our training model on LRP has a total(More)
We present our experience with surgical training programs development for basic and advanced laparoscopic urological surgery. Both training programs consist of 21 and 28 hours respectively. Basic surgical programs start with general knowledge of ergonomics and instrumentation, there after, attendants acquire basic skills on physical simulator.(More)
OBJECTIVE To evaluate muscle activity and hand motion in veterinarians performing a standard set of laparoscopic training tasks. SAMPLE 12 veterinarians with experience performing laparoscopic procedures. PROCEDURES Participants were asked to perform peg transfer, coordination, precision cutting, and suturing tasks in a laparoscopic box trainer.(More)
We present our experience in the design and development of a training program in paediatric and neonatal laparoscopic surgery, and the determination of face validity by the attendants. Data included in the present study was obtained from five consecutive editions of our Neonatal and Paediatric Laparoscopic Surgery Course. Our training model, with a total(More)
Adding to the ergonomic inconveniences already presented by traditional laparoscopy (LAP), laparoendoscopic single-site (LESS) surgery has been found to entail other more specific problems, including greater reduction in movement freedom, in-line vision with loss of triangulation, and greater proximity of instruments. The objective of this study was to(More)
