Utilizing “Disruptive” Endoscopic Techniques: The Role and Future of Endoscopic Surgery for the

Treatment of Symptomatic Conditions of the Spine( an evidence based concept talk)

Health Care Cost is in Crisis… No easy answer

• Affected by stakeholders all competing for services or products causing an affordability crisis

• Privilege or Right?

• Free, single payer, or best solved by a Free market?

• What is the Role of health care providers that has to deliver health care , vs government / insurance payers?

Health Care Affordability is the Crisis

• Affordability is a real challenge without the means to pay for “real quality “

• A growing trend is for hospital and physicians to manage cost-sharing and quality metrics

• What about “disruptive” concepts,

– Treating the pain source surgically with a “warrantee”?

– Ie. surgical pain care with visualized surgical treatment of the pain generator as a staged procedure

My opinion:

Consider “disruptive” techniques that preserve patient choice and physician

autonomy= free market concepts

Endoscopic Spine Care, 5G, Robotic A.I.

Single payer w/o insurance choice, USPO without FEDEX,

I am “Conflicted” by 28 years >11,000 Endoscopic Procedures since 1991

• Developed the YESS™ Endoscopic Spine System 1997

– Personal experience with the first Medicare approved Spine ASC

• Over 140 Level IV and V EBM publications

– Now level 3 with like minded surgical collaborators

– All innovations start as level V

Personal observations

The Background for my “Confliction”

• BACKGROUND: I was a General Orthopedic Surgeon for 20 years, before Spine Fellowship Programs spawned the myriad of fusion procedures considered the “State of the Art”.

• I support current concepts in Spine Surgery, including fusion

– I see the success of fusion for the right indications by my fellowship trained associates at Desert Institute for Spine Care

• After adopting endoscopic spine surgery in 1991, I became passionate about endoscopic spine surgery because it offered greater surgical options, but “disruptive” to traditionalists

Take home message

• Endoscopic surgery on the pain generators of spine symptoms and pain can be correlated with patho-physiology supported by endoscopic documentation

• The patho-physiology of pain is better understood than just reliance on current imaging techniques alone

Initial Response by many traditionaliststo “Disruptive” Surgical Platforms

Why is Endoscopic Spine Surgery ”Disruptive?”

• Eliminates the need for fusion, (the current focus) by 30-

85% (stratified)

– The most costly surgical option

• Decrease the need for more costly Spinal cord stimulation

for FBSS from failed decomoression and fusion

– * I share the DRG neuromodulation method for neuropathic pain

• It mitigates dependence and over utilization of

Opiods by “surgically” treating the pain generator

“surgical pain care”


• Endoscopic decompression accomplished under

local anesthesia by Surgically Trained

Endoscopists as a “STAGED” procedure can

eliminate 70-90 percent of fusions being utilized as

the first option for decompression and stabilization

• Mitigates the fusion solution driving evidence

based medicine studies and 3rd party payment

Scott Becker’s Thoughts on Health Care Systems

• Scott Becker Outlined the headwinds facing Current Trends in health care delivery

• Scott Becker concludes that current medical doctrine…IS NOT Likely to Work in the Next 10 years

• Are Scott Becker’s “other” Issues “DISRUPTIVE”?

–*Endoscopic Spine Surgery for symptomatic conditions of the lumbar spine is Becker’s “other” issue for more cost effectiveness in spine care

My Thoughts on Disruptive Health Care Issues under Becker’s “other” platform

• Convert pay for service to pay for “value”

• The provider issues “value warranty” for the requested fee

• Treat surgeons like PROFESSIONAL ATHLETES where only the very best are paid what they command

My Thoughts on Disruptive Health Care Issues under Becker’s “other” platform

• Educate the next generation of physicians to be competitive in the new era of healthcare by:

– Focusing on what is best for their patient

–Adopting endoscopic “surgical spine care “

– Surgeons offering a “warranty”

• Robotics for endoscopic spine surgery will shorten learning curve, improve results

Current political Situation in the USA

• ”FREE” single payer “ one size fits all” concept will

provide less quality, less choice, rationing, and greater cost

• Health care providers “gaming” the system will add cost by protecting their turf without improving care will be the demise of universal “free” health care

• The Best solution is still be debatable and must be rationed

• Oval design as a surgical tool:– Discectomy, Nuclectomy

• Decompression

– Intradiscal Therapy• Decompression

• Thermal annuloplasty

• Disc irrigation

– Nerve Ablation• Intradiscal annuloplasty

• Rhizolysis• Disc and Axial back pain

Facilitate And augment All Surgical Approaches

Wolf Y.E.S.S™. Multi-Channel Spine different systems in the market

Many Endoscope DesignsFor Diagnosis and Treatment:

Identify Painful Patho-anatomy

YESS Endoscope Provides Endoscopic

Documentation of patho-anatomy of pain

generators: A New EBM concept

The YESS Scope Design: Oval endoscope with Multi-channel flow integrated system ( 1997)

Wolf Award 2017 commemorating 20 years of innovation

NEW 3D SCOPE under development

Oval endoscope configuration facilitates intradiscal therapy visualization in a

narrowed aging spine

( other OEM endoscopes are round)

Oval shape Enhances visualization by a fluid pump that controls

irrigation flow and pressure to keep the endoscopic field clear

Surgical pain treatment is a “disruptive” concept

• The endoscope can document patho-anatomy responsible for symptoms and pain from normal aging

• It can correlate the pathophysiology and symptomatology when endoscopic surgery is performed with pt feedback under local anesthesia

Clinical example: Correlation of

epidurography and “evocative”

discograms with the patho-

anatomy of symptom generation

Video of painful anular tear (1.5 min)

Why is endoscopic spine “disruptive”?Too many stake holders in the spinal care platform

• Surgeons and nonsurgeonswho do not perform endoscopic surgery may have a different opinion about endoscopic spine surgery

• Many are opposed or “agnostic” about it

• Accomplished Endoscopists

requires special surgical training to be proficient

for this “new” concept of “evidence based medicine”


• It will mitigate dependence and over utilization of opiods

and pain management procedures that are easily abused

• Decrease the need for costly Spinal cord stimulation or

nerve and DRG neuromodulation for “FBSS” Pain

• A Yeung owns the foraminal DRG neuromodulation method,

but almost all utilization is by pain management providers

familiar with concepts of Spinal cord stimulation

This experience provides endoscopic “evidence based medicine” by treating the pain and

symptom generator, with endoscopic documentation of the patho-anatomy.

*Traditional imaging requirements to make clinical decisions is not completely accurate

*Neuromodulation can treat neuropathic pain

When the visualized “pain or symptom” generating patho-anatomy is correlated with the patient’s response and feedback during

surgery, a new type of “evidence based” validation of the surgical effect, considered “disruptive” can be studied and validated

The “E” in Endoscopic Evidence Based

Medicine (a new concept)

• E= Evidenced based

• E=Endoscopic Visually Based

• E= Expedient and Efficient Based

• E= Economically Based

• E= EXPERTISE Based

Treat the pain generator, not just the available imaging

The “disruptive” process provides information on pain generators that is not appreciated by traditional spine surgeons and non surgeons.

A. Yeung’s data base of >11,000 surgical procedures on endoscopic surgery under local anesthesia identifies the best indications for

“surgical pain care”

The “YESS” endoscopic philosophy and technique

• Appropriate for patients deemed “too Young”, “too old”, “ too pain sensitive”, with “psychologic disorders” or having “too many co-morbidities” to be good candidates for the risks of traditional surgical intervention

THE BEST TECHNIQUE, as defined by safety through reduction of complications, efficacy,

and cost effectiveness should be adopted by the best results in each individual surgeon’s

hands

“Best” Minimally Invasive Surgical Technique is Transforaminal Decompression under local

anesthesia

• It is Safer than traditional open surgery!

• 3.5% published complication rate

• NOW *< 1%-2% endoscopic complication rate after overcoming the learning curve

– A Yeung’s overall CUMMULATIVE case series

FEATURES of Transforaminal Decompression:

• Clinically Effective, and Cost Effective– Local anesthetic performed with MAC or no sedation

– Outpatient, one hour recovery in ASC, surgical time dependent on case complexity and surgeon experience

– *Neuromonitoring NOT NEEDED ( at cost savings )

– Earlier Surgical Care bypasses less effective nonsurgical methods and more surgically morbid care

The “Surgeon” factor:

Endoscopic surgeons or nonsurgeon providers must develop critical skills, with appropriate training, and gain competency to perform at a high enough skill level needed to attain the safest and best results

Appropriate training, “turf battles”, “hype”,

unaccepting surgeons, FALSE marketing

CONCERNS

A systematic review of A YEUNG’S endoscopic database 10,000 cases 1991-2018

• Discogenic pain validated by evocative chromo-discography with intra-operative vital staining

• Progression to contained, then protruded and extruded HNP of various types

• Progression to foraminal decompression and

foraminoplasty

• Statification of endoscopic indications in past 15 years to present evolution in 2019

Growth of Endoscopic Spine

• ENDOSCOPIC VISUALIZATION ,EXCISION, DECOMPRESSION AND STABILIZATION of the lumbar thoracic and cervical spine Is CURRENTLY BEING PRACTICED WIDELY in ASIA

• Transforaminal Endoscopic Decompression, providing symptom relief is possible for 80%-90% of the Painful Patho-anatomy of each Degenerating symptomatic Spinal Segment

Endoscopic Spine State of the Art

• A “full endoscopic” approach is first promoted by Sebastian Ruetten and others by combining the Translaminar with a Transforaminal approach

– The future will be by combining all endoscopic approaches possibly staged, aided by Robotic A.I.*

• Endoscopic procedures now BEING UTILIZED for trauma, neoplasm, and instability, including fusion as a surgical option for pain resolution from “FBSS”

* ATY’s A.I. for endoscopic techniques

A.I. in computer technology for health care

• Assimilation in Asian countries will be at a much higher rate than the West because it is culture and Asian political policy dependent

• Asia (China) has a large population with relatively lower costs, that “insulate” Asia from loss of low level and blue collar jobs at risk in Advanced Western Countries currently in political turmoil

• *Physician A.I. needs a reimbursement platform to innovate, but under attack because of payment headwinds

Endoscopic Spine as an Academic Endeavor

• The Yeung Endoscopic Spine Center established in 1993 at the University of New Mexico ( Yeung’s Alma Mater) as the

first academic center to create a multidisciplinary program for Endoscopic Spine Procedures. Certification for endoscopic spine surgery graduated it’s first anesthesia trained spine fellow Andrew Roberts, M.D.

• More fellowship trained spine surgeons adopting endoscopic spine to augment their practice

• (D.I.S.C. Phoenix, Arizona)

Endoscopic surgery augments open “gold standard” surgery by adding intradiscal therapy

• Intradiscal therapy: Endoscopic Selective Decompression, thermal ablation , Irrigation, and neutralization of disc pH

• *Endoscopic visualization of patho-anatomy under local anesthesia with patient feedback during surgery is an important aspect of endoscopic evidence based medicine

The future will have Multi-disciplinary contributions,

working together rather than as competitors

Trend: “Moving away from Fusion”

• Fusion is not needed if we can treat the cause of pain early

• Natural healing over time will decrease the need for fusion to treat pain

• Fusion will be for deformity or instability

– Endoscopic MIS Fusion and dynamic stabilization is possible

Appropriate adoption and training will be critical

Key Important Factors

• Appropriate Training

• Adopters must perform the procedures “really well”,

and evolve their own learning curve

• Transparent pricing ( cash vs insurance)

• Practice good EBM ( Evidenced based Medicine )

Disc Degeneration, even in asymptomatic patients has a high Risk of eventually developing low back

pain and sciatica in the normal aging process

Little Known or appreciated Premise?

Common Low Back Pain begins in the disc

• Disc Degeneration in asymptomatic patients increases risk of low back pain

– a prospectively assessment of Southern chinese

– Dino Samartzis, HK University faculty

• New technologies being developed with Yeung involvement*

– Disc shunt

– Imaging ( Nocimed)

– Neuromodulation *( invasive and noninvasive )

– Robotics for endoscopic targeting *

Primary Pain Source:

The Disc• Current research and interest should be with

intradiscal therapy– Validated by level I EBM

Chymopapain

• New technologies for nucleus augmentation, biologics is still in its infancy, but promising

Disc Anatomy

80 Percent support

*The demise of chymopapain is a lesson that even level 1 EBM validated studies can fall

victim to over regulation and risk vs profitability over efficacy. Good training also an issue for poorly trained practioners “ruining”or

discrediting the endoscopic procedure

IS OVER REGULATION AND RECENT PHARMA SHORTAGES and COST THE PROBLEM?

• SHORTAGES OF COMMON INEXPENSIVE ENDOSCOPIC SUPPLIES * SINGLE OR MULTI USE

– SALINE

– WATERSOLUABLE COMPOUNDED STERIODS

• Betamethasone

– VITAL DYES

Clinical Rationale of Endoscopic Treatment

• Intradiscal Therapy ( lumbar spine )

– Validated by Level I studies ( chymopapain)

• Foraminal decompression: Foraminal Decompression vs Foraminoplasty

– ENDOSCOPIC EXCISION and neuromodulation of patho-anatomy

• Dorsal rhizotomy

• Hybrid Procedures incorporating all three Therapies

Endoscopic Surgery is the least invasive Surgical Procedure to treat the patho-anatomy of

chronic back pain and sciatica

New Indications are constantly being developed,

aided by new instrumentation and surgical techniques

• Save Fusion for last, avoiding “ burning bridges” for more invasive procedures as a staged procedure

• Fusion continues to flourish as well, with “new” surgical concepts changing every 10 years

• Many patients want to avoid fusion due to a ”bad” result to or to fear of the paradoxical effects of adjacent level deterioration

FUSION

Clinical Research validates Both Clinical Rationale

• The research design focuses on Evidence Based Medicine: EBM allows us to rate clinical data into :

• Levels of Evidence, I-V

• Grades of Recommendation

• Current focus on SCS and DRG neuromodulation

should be for “ true” FBSS causing neuropathy

The Practice of Evidence Based Medicine is the integration of:

–Clinical Expertise ( starting with level V)

–Patient’s personal Needs and Values

–Best Research Evidence

Evidence Based Medicine

• Almost all physicians feel they are already practicing “Evidence –based Medicine”

–Medical Schools teach and use the scientific method

–Many read medical journals appropriate to their practice

Excerpted from presentation by W. Watters, NASS President

Surgical Concepts on Expertise and Education: ( NASS past president W. Watters)

• “What you think you may know may no longer be valid or become disproven over time with future research”

Patient Values are also Important

• Each patient brings a set of personal beliefs and knowledge base to the patient-physician relationship

• Patients rely heavily upon the recommendations of their physician, family, and friends for personal choices

– Different cultures may have varied beliefs based on their cultural biases that will affect their acceptance of recommended treatment

• Physicians offer guidance to their patients for a joint decision on their choice

The Best Research Evidence

–Reduces bias, which is difficult to overcome, but should be acknowledged

–Promotes ethical clinical decision making and Minimizes outside influences

In Endoscopic Surgery: Cooperation is neededCross training, communication, shared responsibilities

• Training is different

• Background is different

• Concepts are different

• Experience is Different

Technical abilities

are different, and

disruptive for

colleagues with a different

surgical background

Decision making and surgical skills are both necessary and go together.

Training, knowledge of indications, and competency is critical.

(My Greatest Worry: Endoscopic Technique discredited by poorly trained non – surgeons with

no training in surgical anatomy and concepts)

Endoscopic Surgery Advantages

• The endoscope makes it possible to correlate the patho-physiology of pain of with visualized patho-anatomy. (please refer to DISC website, and click on the top 10 playlists)

• Operating under local anesthesia allows the patient to communicate with the surgeon during surgery

• All discs undergo degradation in a well-described cascade, matched by imaging and patho-anatomy

• Why some patients have intolerable Pain, and others is NOT completely understood by imaging alone

• Facilitated by Diagnostic and therapeutic injections

The Future of Endoscopic Surgery

• Utilized by qualified, adequately trained surgeons and nonsurgeons ( both need training )

• Acceptance will depend on the politics, physician acceptance, and the business of spine in various parts of the world

• Outcome of medical and political turf battles

The Future of Endoscopic Surgery

“Surgery” will not be just for a neurologic deficit, an “abnormal“ imaging study, or last resort” for surgical intervention.

Transforaminal Decompression will be for Surgical

Pain CARE, not just “Management” under local

• It has irrigation channels that a laser fiber can be inserted down one channel for laser ablation

• 2 mm- 4.2 mm working channel for surgical instruments

Multiple Endoscope Systems are being marketed

• Other systems are readily Available, with less focus on visualizing intradiscal pathology

• The advantages of the Original YESS oval design still under appreciated as noted by round OEM endoscopes being promoted and marketed that may be simpler to manufacture and use
