The SAGES Fundamental Use of Surgical Energy program (FUSE): history, development, and purpose

From FUSE to a hands-on electrosurgery course using a cadaveric model

INTRODUCTION

Surgical procedures in contemporary practice frequently employ energy-based devices, yet comprehensive education surrounding their safety and effectiveness remains deficient. We propose an innovative course for residents that aims to provide basic electrosurgery knowledge and promote the safe use of these devices.

METHODS

We developed a simulated training course for first-year general surgery and orthopedic residents. First, a survey was conducted regarding their knowledge perception about energy devices. The course consisted of two online theoretical sessions, followed by three in-person practical sessions. First-year residents performed three video-recorded attempts using a cadaveric model and were assessed through a digital platform using the Objective Structured Assessment of Technical Skill (OSATS), a Specific Rating Scale (SRS), and a surgical energy-based devices scale (SEBS). Third-year residents were recruited as a control group.

RESULTS

The study included 20 first-year residents and 5 third-year residents. First-year residents perceived a knowledge gap regarding energy devices. Regarding practical performance, both OSATS and checklist scores were statistically different between novices at their first attempt and the control group. When we analyzed the novice's performance, we found a significant increase in OSATS (13 vs 21), SRS (13 vs 17.5), and SEBS (5 vs 7) pre- and post-training scores. The amount of feedback referred to skin burns with the electro-scalpel reduced from 18 feedbacks in the first attempt to 2 in the third attempt (p-value = 0.0002). When comparing the final session of novices with the control group, no differences were found in the SRS (p = 0.22) or SEBS (p = 0.97), but differences remained in OSATS (p = 0.017).

CONCLUSION

This study supports the implementation of structured education in electrosurgery among surgical trainees. By teaching first-year residents about electrosurgery, they can acquire a skill set equivalent to that of third-year residents. The integration of such courses can mitigate complications associated with energy device misuse, ultimately enhancing patient safety.

Advanced bipolar vessel sealing devices vs conventional bipolar energy in minimally invasive hysterectomy: a systematic review and meta-analysis

PURPOSE

To compare conventional bipolar electrosurgery with advanced bipolar vessel sealing (ABVS) devices for total laparoscopic hysterectomy (TLH).

METHODS

A systematic review was conducted by searching Scopus, PubMed/MEDLINE, ScienceDirect, and Cochrane Library from January 1989 to November 2021. We identified all studies comparing ABVS devices with conventional bipolar electrosurgery in TLH and reporting at least one of the following outcomes: total blood loss, total operative time, hospital stay, perioperative complications, or costs. Meta-analysis was conducted with a random effect model reporting pooled mean differences and odds ratios (ORs) with related 95% confidence intervals (CIs).

RESULTS

Two randomized controlled trials and two retrospective studies encompassing 314 patients were included out of 615 manuscripts. The pooled estimated total blood loss in the ABVS devices group was lower than conventional bipolar electrosurgery of 39 mL (95% CI - 65.8 to - 12.6 mL; p = .004). The use of ABVS devices significantly reduced the total operative time by 8 min (95% CI - 16.7 to - 0.8 min; p = .033). Hospital stay length did not differ between the two groups, and a comparable overall surgical complication rate was observed [OR of 0.9 (95% CI 0.256 - 3.200; p = .878].

CONCLUSIONS

High-quality evidence comparing ABVS devices with conventional bipolar electrosurgery for TLH is lacking. ABVS devices were associated with reduced total blood loss and operative time; however, observed differences seem clinically irrelevant. Further research is required to clarify the advantages of ABVS devices over conventional bipolar electrosurgery and to identify cases that may benefit more from their use.

Use of High Energy Devices (HEDs) versus electrocautery for laparoscopic cholecystectomy: a systematic review and meta-analysis of randomised controlled trials

INTRODUCTION

According to the literature, there is no clear definition of a High Energy Devices (HEDs), and their proper indications for use are also unclear. Nevertheless, the flourishing market of HEDs could make their choice in daily clinical practice arduous, possibly increasing the risk of improper use for a lack of specific training. At the same time, the diffusion of HEDs impacts the economic asset of the healthcare systems. This study aims to assess the efficacy and safety of HEDs compared to electrocautery devices while performing laparoscopic cholecystectomy (LC).

MATERIALS AND METHODS

On behalf of the Italian Society of Endoscopic Surgery and New Technologies, experts performed a systematic review and meta-analysis and synthesised the evidence assessing the efficacy and safety of HEDs compared to electrocautery devices while performing laparoscopic cholecystectomy (LC). Only randomised controlled trials (RCTs) and comparative observational studies were included. Outcomes were: operating time, bleeding, intra-operative and post-operative complications, length of hospital stay, costs, and exposition to surgical smoke. The review was registered on PROSPERO (CRD42021250447).

RESULTS

Twenty-six studies were included: 21 RCTs, one prospective parallel arm comparative non-RCT, and one retrospective cohort study, while three were prospective comparative studies. Most of the studies included laparoscopic cholecystectomy performed in an elective setting. All the studies but three analysed the outcomes deriving from the utilisation of US sources of energy compared to electrocautery. Operative time was significantly shorter in the HED group compared to the electrocautery group (15 studies, 1938 patients; SMD - 1.33; 95% CI - 1.89 to 0.78; I2 = 97%, Random-effect). No other statistically significant differences were found in the other examined variables.

CONCLUSIONS

HEDs seem to have a superiority over Electrocautery while performing LC in terms of operative time, while no difference was observed in terms of length of hospitalisation and blood loss. No concerns about safety were raised.

Impact of the fundamental use of surgical energy certification on surgeons' behavior and awareness of safe use of energy devices: a cross-sectional survey research

BACKGROUND

The Fundamental Use of Surgical Energy (FUSE) program was established to educate surgeons and trainees to promote awareness and behaviors for the safe use of surgical energy devices. Despite its implementation, the impact of FUSE certification on surgeons' behavior and safety awareness regarding practice of energy devices remains unclear. This study aimed to identify the perceived impact of FUSE certification on surgeons' behavior and awareness regarding the safe use of surgical energy devices.

METHODS

We performed a descriptive cross-sectional survey study, using non probabilistic purposive sampling, and distributed 22-item web-based questionnaires among all 59 FUSE-certified surgeons in Japan, excluding operating room nurses and medical students. The questionnaire items covered demographics, surgical techniques using various energy devices, changes in behavior and safety awareness, communication with colleagues about surgical energy devices, and educational activities related to energy devices.

RESULTS

Fifty-seven participants completed the questionnaire (response rate 96.6%). Most surgeons (91.3%) could apply material learned from the FUSE program in practice, especially material related to monopolar electrosurgery. Fifty-six surgeons (98.3%) reported increased awareness of surgical safety, and 35 (61.5%) reported increased communication with operating room personnel about the safe use of energy devices. Moreover, 56 participants (98.3%) indicated a need for systematic education in surgical energy, with participants recommending fellows (94.7% of participants specified that fellows should participate in further education), residents (75.4%), and attending surgeons (63.2%) as the target recipients of this training. Conclusions After FUSE certification, not only did surgeons' knowledge increase, but their energy-related surgical techniques in practice also improved. Furthermore, FUSE-certified surgeons felt that they were more aware of surgical-energy safety and were dedicated to its promotion.

Efficacy of electrocoagulation hemostasis: a study on the optimal usage of the very-low-voltage mode

BACKGROUND

The very-low-voltage (VLV) mode in electrosurgery can stably and deeply energize tissues even if the local electrical resistance changes with energization. Therefore, in electrosurgical hemostasis, the VLV mode is more reliable than other coagulation modes. In clinical practice, the appropriate use of combined saline drip and blood suction under the VLV mode can further enhance coagulation ability. However, the detailed mechanism is not known. The current study aimed to evaluate the association between electrosurgical activation time (ET) and hemostatic tissue effect (HTE) under the VLV mode. Further, the effect of saline drip and suction on power consumption and HTE was validated.

METHODS

Twelve female pigs weighing 35 kg were included in the experiment. A liver hemorrhage model was established via an open abdominal procedure, and hemostasis in the hemorrhagic lesion was attempted using the VLV mode under different conditions (ET: 3, 6, 9, and 12 s, with/without saline drip and/or continuous suction). Electrical data (such as voltage, current, and resistance) during coagulation were extracted. Then, the vertical/horizontal extent of HTE was assessed, and the hemostasis outcome (successful or failed) was recorded.

RESULTS

The vertical/horizontal HTE, power consumption, and integrated current value were positively correlated with the ET. The coagulation depth deepened with saline drip (p < 0.01). However, it was not affected by continuous suction (p = 0.20). The HTE area increased with saline drip (p < 0.01) and decreased with suction (p < 0.01). The power consumption and integrated current increased with saline drip (p < 0.01) and decreased with suction (p < 0.01). The success rate of hemostasis decreased with saline drip alone (31of 48 trials [success rate = 64.5%] in the saline drip group and 44/48 trials (success rate = 91.7%) in the control group). However, it improved with continuous suction (46/48 trials [success rate = 95.8%]).

CONCLUSION

The electrosurgical activation time was positively correlated with hemostatic tissue effect. Saline drip increased heat transfer efficiency but decreased the success rate of hemostasis. Therefore, the use of continuous suction in addition to saline drip increased hemostatic efficiency.

Safer operating room teams: rationale for the fundamental use of surgical energy (FUSE) hospital compliance module

BACKGROUND

The Fundamental Use of Surgical Energy (FUSE) program was developed by The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) to promote the safe use of surgical energy. A curriculum that could be used in hospital educational programs was needed to expand access. The goal of this project was to develop a short, inexpensive, online module that emphasizes key FUSE learning objectives. The accompanying survey assessed perceived relevancy.

METHODS

The SAGES FUSE Committee developed the Hospital Compliance Module. The target audience included all OR personnel. The Module was piloted at Beth Israel Deaconess Medical Center. The data were analyzed using Chi-square with Yates' correction two-tailed test.

RESULTS

Three-hundred-eighty individuals completed the survey: 198 (52%) surgeons, 139 (37%) nurses, 28 (7%) surgical technicians, and 15 (4%) house staff. For "…the Module taught me valuable information" 155 (41%) responded extremely and 350 (92%) responded at least somewhat. For "As a result of [the Module] how likely are you to change how you set up or use energy devices…?" 103 (27%) responded extremely and 305 (80%) responded at least somewhat. For "How likely are you to recommend this compliance module…?" 143 (38%) responded extremely and 333 (88%) responded at least somewhat.

CONCLUSION

The FUSE Hospital Compliance Module is effective and efficient. It should be considered for widespread distribution by hospitals to enhance staff education.

Does your team know how to respond safely to an operating room fire? Outcomes of a virtual reality, AI-enhanced simulation training

BACKGROUND

Operating room (OR) fires are rare but devastating events requiring immediate and effective response. Virtual Reality (VR) simulation training can provide a safe environment for practice of skills in such highly stressful situation. This study assessed interprofessional participants' ability to respond to VR-simulated OR fire scenarios, attitudes, numbers of attempt of the VR simulation do participants need to successfully respond to OR fires and does prior experience, confidence level, or professional role predict the number of attempts needed to demonstrate safety and pass the simulation.

METHODS

180 surgical team members volunteered to participate in this study at Beth Israel Deaconess Medical Center, Boston, MA. Each participant completed five VR OR simulation trials; the final two trials incorporated AI assistance. Primary outcomes were performance scores, number of attempts needed to pass, and pre- and post-survey results describing participant confidence and experiences. Differences across professional or training role were assessed using chi-square tests and analyses of variance. Differences in pass rates over time were assessed using repeated measures logistic regression.

RESULTS

One hundred eighty participants completed simulation testing; 170 (94.4%) completed surveys. Participants included surgeons (17.2%), anesthesiologists (10.0%), allied health professionals (41.7%), and medical trainees (31.1%). Prior to training, 45.4% of participants reported feeling moderately or very confident in their ability to respond to an OR fire. Eight participants (4.4%) responded safely on the first simulation attempt. Forty-three participants (23.9%) passed by the third attempt (VR only); an additional 97 participants (53.9%) passed within the 4-5th attempt (VR with AI assistance).

CONCLUSIONS

Providers are unprepared to respond to OR fires. VR-based simulation training provides a practical platform for individuals to improve their knowledge and performance in the management of OR fires with a 79% pass rate in our study. A VR AI approach to teaching this essential skill is innovative, feasible, and effective.

Intraoperative and postoperative complications in colorectal procedures: the role of continuous updating in medicine

Accepting surgical complications, especially those related to the learning curve, as unavoidable events in colorectal procedures, is like accepting to fly onboard an aircraft with a 10 to 20% chance of not arriving at final destination. Under this condition, it is very likely that the aviation industry and the concurrent reshaping of the world and of our lives would have not been possible in the absence of high reliability and reproducibility of safe flights. It's hard to imagine surgery without any intraoperative and/or postoperative complications. Nevertheless, there is a plenty of room for improvement by simply adopting what has been explicitly and scientifically demonstrated; training outside of the OR, usage of modern information technologies and application of evidence-based perioperative care protocols. Additionally, the possibility to objectively measure and monitor the technical and even non-technical skills and competencies of individual surgeons and even of OR teams through the application of structured and validated assessment tools can finally put an end to the self-referential, purely hierarchical, and indeed extremely unreliable process of being authorized or not to perform operations on patients. Last but not least, a wide range of new technologies spanning from augmented imaging modalities, virtual reality for intraoperative guidance, improved robotic manipulators, artificial intelligence to assist in preoperative patient specific risk assessment, and intraoperative decision-making has the potential to tackle several hidden roots of surgical complications.

Results of the FUSE Evaluation Project in France

BACKGROUND

The Federation of Visceral and Digestive Surgery (FCVD) is in charge in France of the continuing medical education of digestive surgeons. Since 2016 and in collaboration with SAGES, it has offered the Fundamental Use of Surgical Energy (FUSE) program as part of the continuing education for surgeons including eLearning and hands-on workshops.

METHODS

The aim of this study was to evaluate the impact of the FUSE program on the participants by participating in a knowledge test and completing a survey.

RESULTS

485 participants fully completed the knowledge test of 18 questions. Post-test assessment showed an increase in the mean score with respect to pre-test assessment, and the surgeons who have participated to the hands-on workshops had a better score. 304 participants filled the survey of 6 questions. The majority were satisfied by the FUSE program and felt that the objectives were achieved.

CONCLUSIONS

The FUSE program developed by SAGES and adopted by the FCVD in France was very much appreciated by the participants and achieved its educational objectives. Our goal is to spread it as widely as possible to all members of the operating room team.
