Background: Duty hour restrictions and enhanced focus on patient safety have prompted the development of new instruction models for practice of surgical techniques outside the operating room, including models for teaching loop electrosurgical excisional procedure (LEEP), a common procedure that gynecology residents perform to diagnose and manage cervical disease.

Objective: We sought to develop an inexpensive and reusable training model for guided practice opportunities that will improve gynecology residents' LEEP technique.

Methods: Polyvinyl chloride, foam, and a polish sausage are used to simulate the basic anatomy of the vagina and cervix.

Background: Virtual reality (VR) simulators and Web-based instructional videos are valuable supplemental training resources in surgical programs, but it is unclear how to optimally integrate them into minimally invasive surgical training.

Methods: Medical students were randomized to proficiency-based training on VR laparoscopy and endoscopy simulators by two different methods: proctored training (automated simulator feedback plus human expert feedback) or independent training (simulator feedback alone). After achieving simulator proficiency, trainees performed a series of laparoscopic and endoscopic tasks in a live porcine model.

Virtual reality (VR) simulators may enhance surgical resident colonoscopy skills, but the duration of skill retention and the effects of different simulator training methods are unknown. Medical students participating in a randomized trial of independent (automated simulator feedback only) versus proctored (human expert feedback plus simulator feedback) simulator training performed a standardized VR colonoscopy scenario at baseline, at the end of training (posttraining), and after a median 4.5 months without practice (retention).

Background: Virtual reality (VR) simulators for laparoscopy and endoscopy may be valuable tools for resident education. However, the cost of such training in terms of trainee and instructor time may vary depending upon whether an independent or proctored approach is employed.

Methods: We performed a randomized controlled trial to compare independent and proctored methods of proficiency-based VR simulator training.
