OBJECTIVE The objective of this study was to determine the best treatment of incisional hernia, taking into account recurrence, complications, discomfort, cosmetic result, and patient satisfaction. BACKGROUND Long-term results of incisional hernia repair are lacking. Retrospective studies and the midterm results of this study indicate that mesh repair is(More)
BACKGROUND Surgeons are increasingly being scrutinized for their performance and there is growing interest in objective assessment of technical skills. The purpose of this study was to review all evidence for these methods, in order to provide a guideline for use in clinical practice. METHODS A systematic search was performed using PubMed and Web of(More)
The objective of this study was to document the complications, outcomes and causes of obstetric fistulas in East African women who underwent first-time surgical repair. Attention was also paid to social background and characteristics of the patients. Data were collected prospectively from patients operated on in the period from January 2001 to August 2003.(More)
BACKGROUND This study was designed to investigate the incidence of technical equipment problems during laparoscopic procedures. METHODS A video-capturing system was used, consisting of an analog video recorder with three camera image inputs and a microphone. Problems with all technical equipment used by the surgical team, such as the insufflator,(More)
The SIMENDO is an affordable virtual reality simulator designed to train basic psychomotor skills for endoscopic surgery. This study aimed first to establish construct validity by determining which parameters can discriminate groups with different experience levels, and second to establish the extent to which training is useful by determining when(More)
With the introduction of minimally invasive surgery (MIS) the necessity to develop training methods to learn skills outside the operating room (OR) became clear. Several training simulators have become commercially available. However, fundamental research into the requirements for effective and efficient training in MIS is still lacking. Yet in the(More)
The aim of this study was to establish content, face, concurrent, and the first step of construct validity of a new simulator, the SIMENDO, in order to determine its usefulness for training basic endoscopic skills. The validation started with an explanation of the goals, content, and features of the simulator (content validity). Then, participants from(More)
Laparoscopic suturing is one of the most difficult tasks in endoscopic surgery, requiring extensive training. The aim of this study was to determine the transfer validity of knot-tying training on a virtual-reality (VR) simulator to a realistic laparoscopic environment. Twenty surgical trainees underwent basic eye–hand coordination training on a VR(More)
The use of checklists is a promising strategy for improving patient safety in all types of surgical processes inside and outside the operating room. This article aims to provide requirements and implementation of checklists for surgical processes. The literature on checklist use in the operating room was reviewed based on research using Medline, Pubmed, and(More)
Psychomotor skills for endoscopic surgery can be trained with virtual reality simulators. Distributed training is more effective than massed training, but it is unclear whether distributed training over several days is more effective than distributed training within 1 day. This study aimed to determine which of these two options is the most effective for(More)
