Introduction: Second trimester surgical termination of pregnancy by dilation and evacuation (D&E) is a procedure that the Obstetrics and Gynecology (OB/GYN) Residency Review Committee requires training programs to offer to their residents and that many residents desire to learn. However, because of limited numbers of credentialed providers, clinical training opportunities may be limited or not available at their training institutions. Simulated procedures may allow for residents and other learners to be more prepared and capable at the time of their first clinical procedures or advanced skill acquisition.
Methods: We describe the construction of a low-cost task trainer for simulation of ultrasound-guided second trimester uterine evacuation procedures using a preserved pig heart and fetal pig. Residents of OB/GYN used the task trainer and completed a survey to determine its effectiveness as a teaching tool.
Results: With the use of a 5-point Likert scale survey (1 inferior, 5 superior), 13 OB/GYN trainees felt that the task trainer reliably reproduced fetal extraction (4.08), would improve their clinical skills (4.46), and would allow them to obtain the skills required to perform the task in real life (4.38). The similarity of ultrasound images to real-life images had a mean score of 3.69. Additional comments about the usefulness of this task trainer in learning the skills necessary for D&E procedures from the participants were overall positive.
Conclusions: The task trainer for ultrasound-guided second trimester uterine evacuation showed excellent face validity. This low-cost task trainer provides residents and other trainees with a tool to practice ultrasound-guided fetal extraction skills and improve proficiency with D&E outside the operating room. In addition, it increases their confidence in being able to perform the procedure on patients.

Laparoscopic surgery has now become the gold standard in managing most surgical cases. Despite its advantages, working hours and in-theatre training restrictions have prompted trainees to explore alternatives like virtual reality (VR) simulations and box training. Furthermore, given the increased frequency of minimally invasive surgery and the prevalence of musculoskeletal issues among surgeons, there's a growing effort to optimize ergonomics.

Objective: To compare novices' performance on simulated laparoscopic tasks with a box trainer and virtual reality (VR) trainer before and after training on one system, and to compare performance between groups following training.
Study Design: Randomized, prospective study.
Sample Population: Twelve veterinary students without prior hands-on laparoscopic experience were randomly assigned to the box or VR training group.
Background: In low- and middle-income countries (LMICs), laparoscopic surgery is challenging to implement due to limited resources and lack of expert surgeons as teachers. The Global Laparoscopic Advancement Program (GLAP) was developed by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) to deliver sustainable and effective methods for teaching safe laparoscopic surgery. GLAP aims to train surgical leaders and trainees with the goal of eventual in-country replication of GLAP programming.

Introduction: The critical role of emergency physicians in military settings underscores the necessity for a broad and proficient skill set, especially in life-saving procedures such as thoracostomies, endotracheal intubations, and cricothyrotomies, to maintain combat readiness. The current peacetime phase, however, presents challenges in maintaining these skills because of decreased exposure to high-acuity medical scenarios. This decrease in exposure jeopardizes skills retention among military emergency medicine physicians, highlighted by studies showing a significant decline in performance over time because of reduced practice.

Objective Hemodynamically unstable upper gastrointestinal bleeding (UGIB) represents a life-threatening emergency that often lacks adequate high-fidelity training in the insertion of balloon tamponade devices. To address this gap, we developed an affordable task trainer that provides real-time feedback to enhance the training experience for emergency medicine residents. This study aims to evaluate the realism of the task trainer and its impact on residents' confidence in managing massive UGIB.
