Purpose: Current training methods for surgical trainees are inadequate because they are costly, low-fidelity, or have a low skill ceiling. This work aims to expand available virtual reality training options by developing a VR trainer for straight coloanal anastomosis (SCA), one of the Colorectal Objective Structured Assessment of Technical Skills (COSATS) tasks.
Methods: We developed a VR-based SCA simulator to evaluate trainees based on their performance.
Article Synopsis
- This project aims to identify essential leadership skills for surgical residents and create a standardized assessment tool to enhance leadership training in residency programs.
- A modified Delphi process was used, gathering insights from 16 national experts to refine a preliminary list of leadership behaviors from 26 to 27 mapped onto 8 domains.
- The resulting Inpatient Leadership Assessment Device (I-LEAD) offers a cohesive framework for residents and educators, promoting better leadership development in surgical training programs.
Article Synopsis
- Perineal proctectomy is a complex surgical procedure with no current training simulators, prompting researchers to develop and validate specific metrics for performance assessment.
- The study was conducted in three phases: creating metrics through task analysis, obtaining expert consensus on their relevance, and testing their effectiveness in distinguishing performance levels between novices and experts using video assessments.
- Results showed a strong correlation between general and specific performance scores, indicating that the developed metrics are effective in differentiating between the skills of novice and expert surgeons.
Background: Ketamine is used in enhanced recovery after surgery (ERAS) protocols because of its beneficial antihyperalgesic and antitolerance effects. However, adverse effects such as hallucinations, sedation, and diplopia could limit ketamine's utility. The main objective of this study was to identify rates of ketamine side effects in postoperative patients after colorectal surgery and, secondarily, to compare short-term outcomes between patients receiving ketamine analgesia and controls.
