Randomized Controlled Trial Multicenter Study
Validation of a new basic virtual reality simulator for training of basic endoscopic skills: the SIMENDO.
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. ⋯ Content, face, and concurrent validity of the SIMENDO is established. The simulator is considered useful for training eye-hand coordination for endoscopic surgery. The evaluated task could discriminate between the skills of experienced surgeons and novices, giving the first indication of construct validity.

Laparoscopy has become the standard surgical approach to both surgery for gastroesophageal reflux disease and large/paraesophageal hiatal hernia repair with excellent long-term results and high patient satisfaction. However, several studies have shown that laparoscopic hiatal hernia repair is associated with high recurrence rates. Therefore, some authors recommend the use of prosthetic meshes for either laparoscopic large hiatal hernia repair or laparoscopic antireflux surgery. The aim of this article was to review available studies regarding the evolution, different techniques, results, and future perspectives concerning the use of prosthetic materials for closure of the esophageal hiatus. ⋯ Laparoscopic large hiatal/paraesophageal hernia repair with prosthetic meshes as well as laparoscopic antireflux surgery with prosthetic hiatal closure are safe and effective procedures to prevent hiatal hernia recurrence and/or postoperative intrathoracic wrap migration, with low complication rates. The type of mesh, particularly the size and shape, is still controversial and is a matter for future research in this field.
