Virtual Reality as an Affirmative Spin-Off to Laparoscopic Training: An Updated Review

Latest advancements in science lead to drastic improvements in patient health care. Techniques and technology evolved in surgery over the years have resulted in the improvement of patient outcomes by leaps and bounds. Open surgeries previously done for procedures like appendectomy and cholecystectomy evolved into laparoscopic minimally invasive procedures. Such procedures pose few challenges to the surgeons, like lack of tissue feedback and fulcrum effect of the abdominal wall. But training surgeons for such an advanced skill is still following conventional methods. These procedures can be effectively trained using Virtual Reality (VR), which can simulate operations outside the operating room (OR). To maximize the outcomes of VR training, knowledge on various strategies affecting the skills acquisition and retention in VR training is essential. This review collected information from PubMed, EMBASE, Cochrane Library (CENTRAL) databases. Data from the previous ten years are included in the review. This included documents, clinical trials, meta-analysis, randomized controlled trials, reviews, systematic reviews, letters to editors, and grey literature. After an advanced Medical Subject Headings (MeSH) search, we got 59,532 results, and after the application of filters, 189 results showed up. Out of these, studies that were not exclusively relevant to the use of VR in laparoscopic surgery were manually excluded, and a total of 35 articles were included in the study. VR is found to be an excellent training modality with promising outcomes. It helps the surgeons perform the surgery accurately at a faster pace and improves confidence and multitasking ability in OR. Instructor feedback from mentors and deliberate practice of trainees, and early introduction of haptics in VR resulted in the most effective outcomes of the VR training. Box trainers are also compared with VR trainers as they are the cheaper modalities of training. However, this area needs more research to conclude if box trainers can act as a cheaper alternative to VR training providing similar outcomes.
