The Surgeon's View: Comparison of Two Digital Video Recording Systems in Veterinary Surgery

Comparative analysis of GoPro and digital cameras in head and neck flap harvesting surgery video documentation: an innovative and efficient method for surgical education

BACKGROUND

An urgent need exists for innovative surgical video recording techniques in head and neck reconstructive surgeries, particularly in low- and middle-income countries where a surge in surgical procedures necessitates more skilled surgeons. This demand, significantly intensified by the COVID-19 pandemic, highlights the critical role of surgical videos in medical education. We aimed to identify a straightforward, high-quality approach to recording surgical videos at a low economic cost in the operating room, thereby contributing to enhanced patient care.

METHODS

The recording was comprised of six head and neck flap harvesting surgeries using GoPro or two types of digital cameras. Data were extracted from the recorded videos and their subsequent editing process. Some of the participants were subsequently interviewed.

RESULTS

Both cameras, set at 4 K resolution and 30 frames per second (fps), produced satisfactory results. The GoPro, worn on the surgeon's head, moves in sync with the surgeon, offering a unique first-person perspective of the operation without needing an additional assistant. Though cost-effective and efficient, it lacks a zoom feature essential for close-up views. In contrast, while requiring occasional repositioning, the digital camera captures finer anatomical details due to its superior image quality and zoom capabilities.

CONCLUSION

Merging these two systems could significantly advance the field of surgical video recording. This innovation holds promise for enhancing technical communication and bolstering video-based medical education, potentially addressing the global shortage of specialized surgeons.

What's the evidence? A review of current instruction and assessment in veterinary surgical education

Veterinary surgical education is improved by studying the relevant literature. The aim of this literature review was to report the theory and methods used to provide surgical education to veterinary students; to discuss the training most likely to create a competent general practitioner; and to review assessment methods for simulated and live surgeries. The literature reviewed demonstrates that new graduates are expected to perform small animal sterilization, dental extraction, onychectomy, abscess treatment, aural hematoma repair, and mass removal with little or no supervision. Students require repetitive practice to reach competence; some practice can take place in a clinical skills laboratory on models or cadavers. When training novices, distributing practice over a longer time improves retention, but months without practice causes skills to decay. Suturing skills may be taught on models at a ratio of 1 instructor per 10 students. Veterinary students require 6-10 repetitions of each small animal sterilization surgery to reach competence; however, learning curves for other surgeries have not been established. Assessment of surgical skills has been undertaken using objective structured clinical examinations (OSCEs) and observed model and live surgeries. Additional validated rubrics are needed in the field. Surgical educators are urged to continue to search for innovative ways to foster deliberate practice, assess skill, and provide feedback for students.

Reshaping surgical specialist training in small animal surgery during and after the COVID-19 pandemic

Objective

To assess the perceived effects of the COVID‐19 pandemic on small animal surgical specialist training, among trainees and supervisors and to propose changes, based upon the results, that could be incorporated into training programs.

Study Design

Anonymous online questionnaire survey.

Sample Population

Eighty‐one eligible responses were collected in September 2020, including 52 European College of Veterinary Surgeons (ECVS) residents and 29 ECVS Diplomates acting as supervisors.

Methods

Descriptive statistics were used to analyze the data. Fisher's exact test was used to test for significance.

Results

A reduction in surgical case load was reported by 82% (n = 66/81) of respondents, with 82% (n = 54/66) of those believing that COVID‐19 had a mild‐to‐moderate impact on training. Compared to supervisors, residents were less likely to feel that appropriate guidance, a safe working environment, and measures to preserve training had been provided (p < .01). Only 45% (n = 22/49) of residents reported confidence with performing teleconsultations. Ninety percent (n = 73/81) of respondents considered online “case presentations” and “edited surgical video footage” as a positive ancillary tool.

Conclusion

COVID‐19 has resulted in a reduction in case load and training for the majority of residents. A discrepancy between the opinions of residents and supervisors was noted on various aspects of COVID‐19 related effects.

Impact

Open communication, as well as the use of additional training tools through digital platforms may help to preserve safe and effective training during times of decreased clinical activity. While this study has focused on surgical specialist training, the results could be applied to other disciplines.

Learner Satisfaction and Experience With a High-definition Telescopic Camera During Vaginal Procedures: A Randomized Controlled Trial

OBJECTIVE

The aim of this study was to compare learner satisfaction and experience with a table-mounted, projecting, high-definition telescopic camera system (VITOM) versus traditional learner observation during vaginal surgery.

METHODS

Medical student and resident learners were randomized to vaginal surgery observation with or without the use of VITOM. We collected data on learner characteristics and their experience with vaginal surgery. After the surgery, learners completed the faculty/preceptor and working environment domains of the Veterans Affairs Learner's Perceptions Survey (VA LPS). The primary outcome was learners who were "very satisfied" on the VA LPS faculty/preceptor domain. We queried their ability to observe the surgery and satisfaction with learning in the operating room using a 100-mm visual analog scale.

RESULTS

Ninety-two learners completed the study (n = 44 VITOM, n = 48 no VITOM). There was no significant difference between groups in the proportion of learners "very satisfied" on the VA LPS faculty/preceptor domain (93.2% VITOM vs 91.5% no VITOM; odds ratio, 1.27; 95% confidence interval, 0.20-9.19; P = 0.99). Learners in the VITOM group were more likely to report ability to see what the main surgeon was doing (93.2% VITOM vs 62.5% no VITOM; odds ratio, 8.02; 95% confidence interval, 2.07-46.32; P < 0.01). Using the visual analog scale, learners in the VITOM group reported higher satisfaction with learning in the operating room (median, 96 [interquartile range, 89-100] VITOM vs median, 80 [interquartile range, 57-98] no VITOM; P < 0.01).

CONCLUSION

The use of a table-mounted, projecting, telescopic camera system during vaginal surgery showed no difference in learner satisfaction on validated questionnaires but resulted in improved experience and visualization.

Video Technologies for Recording Open Surgery: A Systematic Review

Video recording of surgical procedures is an important tool for surgical education, performance enhancement, and error analysis. Technology for video recording open surgery, however, is limited. The objective of this article is to provide an overview of the available literature regarding the various technologies used for intraoperative video recording of open surgery. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines using the MEDLINE, Cochrane Central, and EMBASE databases. Two authors independently screened the titles and abstracts of the retrieved articles, and those that satisfied the defined inclusion criteria were selected for a full-text review. A total of 2275 publications were initially identified, and 110 were included in the final review. The included articles were categorized based on type of article, surgical subspecialty, type and positioning of camera, and limitations identified with their use. The most common article type was primary-technical (29%), and the dominant specialties were general surgery (22%) and plastic surgery (18%). The most commonly cited camera used was the GoPro (30%) positioned in a head-mount configuration (60%). Commonly cited limitations included poor video quality, inadequate battery life, light overexposure, obstruction by surgical team members, and excessive motion. Open surgery remains the mainstay of many surgical specialties today, and technological innovation is absolutely critical to fulfill the unmet need for better video capture of open surgery. The findings of this article will be valuable for guiding future development of novel technology for this purpose.
