Post-intubation tracheal stenosis was a late time complication after tracheotomy but the happening of dyspnea was unusual. Diagnosing tracheal stenosis after incubation, and figuring out the location and causes of the stenosis were important. Treatment of post-incubation tracheal stenosis relied on accurate diagnosis of the type of tracheal stenosis. Computed tomography (CT) and laryngoscope could be used for detecting the stenosis but not enough. Two patients who were already under the urgent tracheotomy over 1 year were reported...

BACKGROUND: Intracorporeal suturing is one of the most important and difficult procedures in laparoscopic surgery. Practicing on a FLS trainer box is effective but requires large number of consumables, and the scoring is somewhat subjective and not immediate. A virtual basic laparoscopic skill trainer (VBLaST©) was developed to simulate the five tasks of the FLS Trainer Box. The purpose of this study is to evaluate the face and content validity of the VBLaST suturing simulator (VBLaST-SS©)...

INTRODUCTION: Virtual reality (VR-)trainers are well integrated in laparoscopic surgical training. However, objective feedback is often provided in the form of single parameters, e.g., time or number of movements, making comparisons and evaluation of trainees' overall performance difficult. Therefore, a new standard for reporting outcome data is highly needed. The aim of this study was to create a weighted, expert-based composite score, to offer simple and direct evaluation of laparoscopic performance on common VR-trainers...

Endoscopic sinus and skull base surgeries are minimally invasive surgical techniques that reduce postoperative symptoms and complications and enhance patients' quality of life. However, to ensure excellent surgical outcomes after such interventions, intimate familiarity with important landmarks and high-level endoscope manipulation skills are essential. Cadaver training is one possible option, but cadavers are expensive, scarce, and nonreusable and cadaver work requires specialized equipment and staff. In addition, it is difficult to mimic specific diseases using cadavers...

Dr. William Halsted started residency-based surgical training at Johns Hopkins University in 1889. On the job training(OnJT) conducted there is an in-hospital training that residents imitate what senior doctors are doing with their patients. [ See one, do one, teach one] is the word briefly expressing this traditional training. Since then all surgeons learned surgery from the mentors and senior doctors in this way. In this OnJT, surgeons spent many years and years and accumulated experience and tried to crime up step by step from beginners to experts...
