Abstract
We come to realize the importance of “telehealth” during the current COVID-19 pandemic. Telehealth can be defined as
providing health care, including preventive, diagnostic, and treatment services, by using information and
communication technologies such as videoconferencing, electronic messaging, and telephone calls (1). With the rapid
development of new treatment technology, communication, and fast speed networks, not only telehealth can provide
medical services closer to home, but it also should provide the doctors and patients with additional benefits of safety,
effectiveness, and satisfaction. HIFU is a new non-invasive ablation treatment for many solid tumors. This paper
illustrates how the potential practice of HIFU ablation for fibroids can be modified to make it suitable for doctors in
their HIFU training for treatment of fibroids and adenomyosis and for patients who need surgery using this new
telehealth development.

1. Introduction
The Coronavirus pandemic has made history and revolution in medicine, not because it is a widespread pandemic
infecting more than 25 million people; it also affects the way of life of healthcare providers and patients worldwide.
During the pandemic, doctors are advised to reduce face- to-face appointments with patients who might display
symptoms of COVID-19 infection, like cough, running nose, headache, and weakness (2, 3). Hundreds to thousands of
patients requiring medical consultations and subsequent surgeries would not be allowed to enter hospital clinics or
hospitals because all medical facilities are fully used to cope with the COVID-19 crisis. It is said to minimize the risks of
cross infections due to overcrowding of high risks patients. While the traditional medical model requiring doctor-
patient interactions in clinics and hospitals is severely affected, the medical systems in many western countries have
reached a crisis.
The poor situations occur in women having a non-urgent gynecological disease such as fibroids and adenomyosis with
heavy bleeding and severe anemia, adenomyosis with intolerable period pain, and many others. Non-urgent operations
are postponed or canceled; even surgeries are indicated. Everything of the routine healthcare services appears to stop
to provide services. Actions are taken in many countries to transform medical practice using telemedicine and
telesurgery in clinics or sites outside the acute hospitals. Furthermore, this global pandemic on doctors’ education and
training has been affected at all levels and in all countries. Robson and Grabau, 2020 (4) further echoed that the impact

of COVID -19 on medical education is unprecedented, far -reaching, and presents a great challenge. Most healthcare
providers have realized that they have to adopt or initiate digital solutions (5).
The high-Intensity focused ultrasound (HIFU) ablation treatment is one of the latest developments, which is increasingly
used to treat uterine fibroids, adenomyosis, and solid cancers (6-8). It is a local thermal ablation technique that destroys
tumors by the thermal effect through the focused ultrasound energy generated from an extracorporal transducer. The
ultrasound beams penetrate the body’s tissues and are focused on the tumor to produce the maximal h eat effect to
induce coagulative necrosis. Some patients with fibroids, adenomyosis, or small solid tumors can have HIFU treatment
under conscious sedation in an outpatient clinic (9). Nearly all patients tolerate the procedure well, and they spend 1 to
2 hours rest after HIFU ablation and return home in a couple of hours and back to work within days.
More importantly, the ultrasound-guided HIFU system enables doctors to operate on a computer console under direct
ultrasound monitoring. Coupled with a high -speed internet environment, doctors can now learn HIFU therapy online,
be supervised performing HIFU surgery via remote monitoring, and even expert HIFU surgeons can perform HIFU
telesurgery via a high-speed 5G network.
From the beginning of the COVID-19 pandemic, the author has accumulated experience over a few months about using
HIFU telehealth services via the social communication platform for his patients and training doctors. The following HIFU
telehealth applications were taken and listed as follow
Online medical consultations with patients. A preliminary exchange of information and arrangement of
investigations, including blood tests and outpatient MRI scans, were conducted. However, due to the lack of
agreed financial arrangement, and legal implications of online medical consultation, patients were still required
to return for assessment before HIFU surgery.
Distant teaching and learning of HIFU surgery from online presentations and discussion platforms were
feasible and popular during the COVID-19 pandemic (Figure 1).
The author adopted webinar meetings on HIFU up to 4 -5 online overseas meetings a month. It is much more
frequent and popular than conventional meetings that need him to travel.

The well-known commercial platforms are Zoom, Skype, Microsoft team, Facebook…etc. This future communication
technology enables doctors to learn the HIFU surgery at a site away from the hospitals or clinics to share patient’s
information and doctors’ skills. Now online HIFU training and surgery demonstrations had available from some
websites in China.
1.1. Monitoring and supervision of surgery at a remote location
There are inadequate HIFU experts because HIFU doctors take a long time (about 3-6 months) to get proficiency and
become an experienced HIFU surgeon to operate without supervision. Their level of skill and knowledge is not easy to
achieve. Therefore many doctors initially need supervision at centers that may not have HIFU experts to supervise.

Chongqing HAIFU Medical Technology Ltd has established a telemedicine center that provides a monitoring and
supervision platform in a large room with multiple large monitors on the wall (Figure 2).

Doctors who were performing HIFU ablations for fibroids, adenomyosis, or other solid tumors from other remote
centers, including Hong Kong, Taiwan, Singapore…etc. could have remote supervision by a training team of HIFU experts
at this center. Doctors from new HIFU centers can then perform their HIFU ablation confidently with this backup
support. When necessary, prompt teaching or advice was given over the audio connection. Real-time ultrasound images
during HIFU abla tion were monitored, with each step of the procedure supervised. That is a good model to be used
across the globe for doctors’ training and supervision in this new area of non-invasive HIFU surgery.
1.2. Remote surgical operation (via 5G network)
The possibility of operating HIFU remotely and utilizing an expert HIFU surgeon’s technical skill over a long distance
has attracted much attention. Coupled with China’s rapid technology development, the authors had reported the world’s
first successful HIFU telesurgery through the 5G network on October 14, 2019, in Shanghai, China (Figure 3).
Figure 3 Dr. Xu conducted a HIFU telesurgery for fibroid ablations on a 30 km away patient.
When long-distance travel or mobilization may not be possible when there is another wave of COVID viral pandemic,
remote HIFU telesurgery development will enable HIFU ablation to be completed in remote locations or clinics outside
hospitals. Therefore any HIFU center in a hospital has a dedicated high-speed 5G network line, then remote cooperative
HIFU treatment between it and a remote HIFU center can be possible.

2. Areas of future development
However, areas that must be resolved before remote HIFU telehealth services are popular and feasible.
i. Online medical consultation and assessment for the suitability of HIFU treatment should be encouraged. Apart
from clinical histories, blood tests, and general fitness for surgery, the appropriateness and suitability for HIFU
treatment depend on the MRI scan. Increased online medical consultations with the patients and online pre -
operative assessment of their MRI images will reduce their need for multiple on -site medical consultations or
travel to clinics and hospitals. This also empowers patients to select the most appropriate healthcare provider
or hospital.
ii. Tele-monitoring and supervision of HIFU ablation at remote HIFU centers require the setting up of good clinical
practice training, standard operating procedures, and close monitoring of treatment procedures. This will
ensure the safety and effectiveness of HIFU treatment.
iii. For HIFU telesurgery to be practical, the following issues also have to be resolved
Pre-operative or postoperative HIFU ablation management is equally important, but the advice may not be
available in the remote area or neglected.
The interference from electricity surges and machines broke down in any of the two collaborative sites could
halt the operation or create unexpected sequels.
Indemnity and legal coverage for HIFU telesurgery activities must be established. The legal responsibility for
any unexpected adverse outcome arising from system errors must be resolved.
iv. The tele-clinical skill assessment: HIFU ablation system allows remote monitor ing from a remote location (as
discussed above). It thus enables the implementation of a new paradigm for clinical skill assessment. After
completing HIFU training, doctors can perform the HIFU ablation under close monitoring for assessing their
competency, accuracy, and skill at the time of HIFU ablation at a distance.
v. The tele -clinical trial – clinical safety and effectiveness of any new therapy require clinical trials for new
treatment protocols. Various tele-trials programs have been successfully developed for cancer treatment trials
closer to Australia’s home (10). Similarly, the tele -clinical trial framework for HIFU ablation treatment for
fibroids and adenomyosis can be an important development in the future.
3. Discussion
Today, we are at the cross way of a ‘telehealth’ revolution. Telehealth has gained acceptance across many healthcare
services to deliver patients with care closer to home. It is expected that the telemedicine market is expected to rise.
Suppose the surgical areas are to be further d eveloped. In that case, the tele -HIFU system will be an appropriate
telehealth application for training, supervision, assessment, and long distant HIFU treatment soon.
Before accepting HIFU into the “telehealthcare ” on a broader scale, many other issues will need to be resolved. For
example, the HIFU ablation should establish standard clinical protocols, global training, and compatibility of HIFU
equipment must be developed. The known risks of hackers to create a ri sk of interference with communications
networks or image signals need much attention. When security and privacy in a HIFU telehealth platform are being
interfered with, it makes a bad image on record, interfering with accepting this new HIFU telesurgery.
Even before the end of this viral pandemic, we should be well prepared to cope with another viral pandemic in the
future. We can therefore now think of it as a ‘telehealth’ revolution. HIFU is a new technology. After its incorporation
with telehealth technology, we probably help lower the barriers among hospitals, doctors, and patients to prepare and
improve patients’ services despite any future viral pandemic.
As we can recognize HIFU telesurgery’s potential increases, there will be business opportunities for communication
companies and medical device manufacturers to embrace the HIFU telehealth revolution over the coming years. Future
development, including additional AI solutions to incorporate into this HIFU ablation system, will improve the
effectiveness and safety of its treatment and enhance overall patient satisfaction. Digital incorporation in HIFU ablation
is an opportunity to drive the Industry for more development.
Finally, legal implications, patients’ privacy, doctors’ responsibility, network security, and machine reliability must be
resolved before the widespread use of this area of HIFU development.

4. Conclusion
After the COVID-19 pandemic, we come to realize the potential role of HIFU “telehealth” to provide education, training,
supervision, and remote telesurgery. HIFU technology and fast speed communication network development can provide
this non -invasive treatment to women with fibroids and adenomyosis closer to home, with the benefits of safe ty,
effectiveness, and patients’ satisfaction. Even this ongoing pandemic shows that HIFU telehealth treatment for fibroids
and adenomyosis had been increasingly used wherever the HIFU service is available. It does not have an increased risk
of transmission of SARS-CoV-2 or other viral infection. Thus, HIFU telehealth could be the preferred treatment option
in the future.
