PURPOSE Limited access to adequate cancer surgery training is one of the driving forces behind global inequities in surgical cancer care. Affordable virtual reality (VR) surgical training could enhance surgical skills in low- and middle-income settings, but most VR and augmented reality systems are too expensive and do not teach open surgical techniques commonly practiced in these contexts. New low-cost VR can offer skill development simulations relevant to these settings, but little is known about how knowledge is gained and applied by surgeons training and working in specific resource-constrained settings. This study addresses this gap, exploring gynecologic oncology trainee learning and user experience using a low-cost VR simulator to learn to perform an open radical abdominal hysterectomy in Lusaka, Zambia. METHODS Eleven surgical trainees rotating through the gynecologic oncology service were sequentially recruited from the University Teaching Hospital in Lusaka to participate in a study evaluating a VR radical abdominal hysterectomy training designed to replicate the experience in a Zambian hospital. Six participated in semi-structured interviews following the training. Interviews were analyzed using open and axial coding, informed by grounded theory. RESULTS Simulator participation increased participants' perception of their surgical knowledge, confidence, and skills. Participants believed their skills transferred to other related surgical procedures. Having clear goals and motivation to improve were described as factors that influenced success. CONCLUSION For cancer surgery trainees in lower-resourced settings learning medical and surgical skills, even for those with limited VR experience, low-cost VR simulators may enhance anatomical knowledge and confidence. The VR simulator reinforced anatomical and clinical knowledge acquired through other modalities. VR-enhanced learning may be particularly valuable when mentored learning opportunities are limited.

Head Mounted Displays

Virtual Reality and Augmented Reality Head-Mounted Displays (HMDs) have been emerging in the last years. These technologies sound like the new hot topic for the next years. Head-Mounted Displays have been developed for many different purposes. Users have the opportunity to enjoy these technologies for entertainment, work tasks, and many other daily activities. Despite the recent release of many AR and VR HMDs, two major problems are hindering the AR HMDs from reaching the mainstream market: the extremely high costs and the user experience issues. In order to minimize these problems, we have developed an AR HMD prototype based on a smartphone and on other low-cost materials. The prototype is capable of running Eye Tracking algorithms, which can be used to improve user interaction and user experience. To assess our AR HMD prototype, we choose a state-of-the-art method for eye center location found in the literature and evaluate its real-time performance in different development boards.

Background. Laparoscopic surgery has gained popularity in the last few decades replacing open standard techniques in several procedures. While its use and scope expand, a standardized method of training and assessment in laparoscopic skills is lacking. Aim. To assess the effect of virtual reality (VR) training on laparoscopic surgical skills. Materials and Methods. It is a prospective, controlled study conducted at Sagar Hospital’s skill lab and Shanthi Hospital and Research Centre (SHRC). We included 27 post graduates in general surgery. They were divided into two groups. One group underwent training in VR Simulator for one week, 30 minutes each day. The second group received no training. Their proficiency while mobilizing the Gallbladder from its liver bed was assessed using a validated scale by a single blinded observer. Results. The statistical analysis was done using a non-parametric test (Mann-Whitney U test). Residents who underwent training in VR simulator got better scores in Overall rating and also in individual parameters when compared with the control group (P = <0.05). Conclusions. Laparoscopic surgical skills can be increased by using proficiency-based VR simulator training and it can be transferred to actual operations. VR simulators are a valid tool for laparoscopic surgical skills training.

PURPOSE Worldwide, more than 80% of people diagnosed with cancer will require surgery during their disease course, but only 5% to 20% of low- and middle-income countries have access to safe, affordable, and timely surgery. Developing surgical oncology skills requires significant time and mentoring. Virtual reality (VR) simulators can reduce the time required to master surgical procedures but are prohibitively expensive. We sought to determine whether a VR simulator using low-cost computer gaming equipment could train novice surgeons in Africa to perform a virtual radical abdominal (open) hysterectomy (RAH). METHODS Our RAH VR simulator used the Oculus Rift (Oculus VR, Menlo Park, CA), a VR headset with hand controllers that costs less than $1,500. Surgical novices learned to perform five key steps of a virtual RAH. We measured and identified predictors of movement and time efficiency for the simulation. RESULTS Ten novice surgeons in Lusaka, Zambia, enrolled in the study. Movement and time efficiency greatly improved over time. Independent predictors of movement efficiency were number of simulations, surgical experience, and time since college graduation. Independent predictors of time efficiency were number of simulations, surgical experience, days between simulation sessions, age, sex, and an interaction between number of simulations and surgical experience. CONCLUSION Low-cost VR may be an effective tool to help surgical novices learn complex surgical oncology procedures. If learning to perform VR surgical procedures with low-cost hardware leads to faster mastery of surgical procedures in the operating room, low-cost VR may represent one of the solutions to increasing access to surgical cancer care globally.

Background:Diffuse laminar endocervical glandular hyperplasia is extremely rare with only 14 cases reported in the literature. Diffuse laminar endocervical glandular hyperplasia is a benign lesion that is easily confused with malignancy.Case Report:We present a 22-year-old woman referred to our gynecologic oncology service with a 2.0 × 4.0-cm exophytic cervical mass. Colposcopic-directed cervical biopsies were diagnosed as adenocarcinoma, suggestive of minimal deviation adenocarcinoma. Computed tomographic scans of the abdomen and the pelvis failed to reveal any metastatic foci. A radical abdominal hysterectomy with pelvic and para-aortic lymph node sampling was performed without complications. Final pathology revealed diffuse laminar endocervical glandular hyperplasia.Conclusions:Diffuse laminar endocervical glandular hyperplasia is an uncommon histological type of pseudoneoplastic glandular lesions that may be found in the cervix, and this entity should be considered in the differential diagnosis of a potentially malignant endocervical glandular lesion.

Abstract Background The value of virtual reality (VR) simulators for robot-assisted surgery (RAS) for skill assessment and training of surgeons has not been established. This systematic review and meta-analysis aimed to identify evidence on transferability of surgical skills acquired on robotic VR simulators to the operating room and the predictive value of robotic VR simulator performance for intraoperative performance. Methods MEDLINE, Cochrane Central Register of Controlled Trials, and Web of Science were searched systematically. Risk of bias was assessed using the Medical Education Research Study Quality Instrument and the Newcastle–Ottawa Scale for Education. Correlation coefficients were chosen as effect measure and pooled using the inverse-variance weighting approach. A random-effects model was applied to estimate the summary effect. Results A total of 14 131 potential articles were identified; there were eight studies eligible for qualitative and three for quantitative analysis. Three of four studies demonstrated transfer of surgical skills from robotic VR simulators to the operating room measured by time and technical surgical performance. Two of three studies found significant positive correlations between robotic VR simulator performance and intraoperative technical surgical performance; quantitative analysis revealed a positive combined correlation (r = 0.67, 95 per cent c.i. 0.22 to 0.88). Conclusion Technical surgical skills acquired through robotic VR simulator training can be transferred to the operating room, and operating room performance seems to be predictable by robotic VR simulator performance. VR training can therefore be justified before operating on patients.
