2What is NOTES?
- Natural Orifice Translumenal Endoscopic Surgery
- Intentional puncture of one of the viscera (e.g.,
stomach, rectum, vagina, urinary bladder) to
access the abdominal cavity - With an endoscope (flexible or stiff)
- To perform an intraabdominal operation
- Pearl JP, Ponsky JL J Gastrointest Surg. 2007

15The Wilk-Patent 1994
US Patent 5297536 Wilk Peter, 1994
- Method for use in
- intra-abdominal surgery
16Rationale for NOTES
- No abdominal wall incisions
- No wound infections and hernias
- Less pain
- Less adhesions
Is NOTES less invasive than any other kind of
surgery???
- NO scars ? perfect cosmetic outcomes

17Importance of cosmetics
18Importance of cosmetics
19Geneva Cosmesis Study
- Onsight poll at "day of open wards ongoing
interviews - Questionnaire
- Importance of cosmetic issues in abdominal
surgery - Satisfaction with previous scars
- Favoritism of scarless surgery
- Favoritism of scarless surgery if risks are
increased - Accepted percentage of risk rise
- Importance of further research and investments
Questions answered on VAS from 0 to more than
100 or 1 to 10
20Conclusion Geneva cosmesis study
- People strongly favor the idea of scarless
abdominal surgery - No differences between genders have been found
- Certain risks are accepted in order to achieve
scarless surgery - Further research and investments seems important
? People have a desire for NOTES!!!
21Rationale for NOTES II
The NOTES-concept Human ingenuity and
technological advance can continue to reduce the
trauma and discomfort of effective surgery

24NOTES Perform with what?
- Current technology
- Flexible endoscopes
- Rigid Scopes
- Limited number of flexible instrumentation
- Limited hemostatic devices
- Cautery
- Bands
- Clips
- Overtubes
- Guidewires
- Stents
- Balloons
BUT ? All instrumentation not designed for
intraabdominal surgery
25Gastroenterologists NOTES
26Technical problems of NOTES
- Access to abdominal cavity
- Pneumoperitoneum
- Intra-peritoneal navigation
- Orientation
- Stable platform
- Tissue manipulation
- Specimen extraction
- Access site closure
No specific NOTES instrumentation on the
market!!!
27Access Endoscopic Trocar
- Endoscopic Veress Needle Overtube Cannula
- Reduced instrument exchanges
- (Re)intubation pathway
- Insufflation and desufflation
- Supports scope shaft

29Closure TASTissue Apposition System
- T-tag applier knotting element
- 2.8 mm channel
- Closure of porcine colon perforation demonstrates
equivalency to surgery with advantages for
adhesion formation

35Every day you may make progress. Every step may
be fruitful....You know you will never get to the
end of the journey. But this, so far from
discouraging, only adds to the joy and glory of
the climb. Sir Winston Churchill British
politician (1874 - 1965)
36The State of NOTES 11/2008
- Extreme skepticism has been replaced with
optimism - Acute feasibility in animals, across a wide range
of procedures, is proven human cases are
starting to be performed with ethical approval in
prestigious institutions (Worldwide experience
300 cases). - Questions of can we yielded to should we and
are now yielding to questions of how can we do
this responsibly? - Killer applications are becoming clearer with
cholecystectomy and bariatric procedures being
targeted - NOSCAR has been formed, bridging SAGES and ASGE
with new European and Latin American associations
37Does NOTES have a future?
NOTES, by addressing Sources of Invasion,
represents the next logical progression of
surgical development, a key step along the MIS
continuum

NOTES
Laparoscopically-Assisted Endoscopy
- Sources of Invasion
- Abdominal wall incisions
- Post-op recovery/RTNA
- General anesthesia
- Financial burden
- Site of care
- Infrastructure requirements
- Clinician skill level
Cholecystectomy
?
Appendectomy
?
Ventral Hernia
?
Diagnostic Peritoneoscopy
?
38The future is hard to predict
39We must not say every mistake is a foolish

40The effect of NOTES
- Less invasive - New approaches
- More invasive - New, effective instruments for
intralumenal manipulation
41Protecting valuables!
