What is MIS? A minimally invasive medical procedure is defined as one that is carried out by entering the body through the skin or through a body cavity or anatomical opening, but with the smallest damage possible to these structuresIncludes laparoscopic, endoscopic, and other approaches. Why MIS? Decreased patient pain Decreased patient recovery period Possible decrease in inflammatory response in the patient which may prove to have a better outcome in oncologic operations. Distant future In the distant future, there will be a para- digm shift with the development of non-inva- sive surgical techniques in combination with nanotechnologies and a new era in the devel- opment of surgery, and subsequently in surgi- cal techniques, will be opened. Nanotechnology is an umbrella term for materials and devices that operate at the nanoskill (1 billionth of a meter). In terms of scale, a nanometer is approximately one 1/8000 of a human hair or 10 times the diam- eter of a hydrogen atom. The size of the device can vary but starts from a ten thou- sand-logic element system that will occupy a cube of no more than one hundred nanome- ters. This is a volume slightly larger than 0.001 cubic microns. This would be sufficient to hold a small computer. For example, if red blood cells are approximately eight microns in diameter, the 100 nanomicroprocessor will be 80 times smaller than a red blood cell. Devices this size could easily fit into the circulatory system and could even conceivably enter indi- vidual cells.

and Emerging Trends
Dr. Sreejoy Patnaik

2. History of Laparoscopy
The first description dates to Hippocrates in
Greece, for use of a speculum to visualize
the rectum (460–375 BC).
A three bladed speculum was found in the ruins
of Pompeii*.
*A roman town buried by a volcano eruption
near modern Naples, Italy - 79 AD).

3. History of Laparoscopy
 1806: Philip Bozzini developed an
instrument called a Lichtleiter
(light-guiding instrument)
 1853: Antoine Jean Desormeaux
used Bozzini’s Lichtleiter
 1867: Desormeaux used an open
tube to examine the genitourinary
tract

4. History of Laparoscopy
Maximilian Nitze (1848 – 1906)
invented the first cystoscope
(Nitze-Leiter cystoscope) using an
electrically heated platinum wire
for illumination.
In 1887, he modified Edison`s light
bulb and created the first electrical
light bulb for use during urological
procedures.
Original carbonfilament bulbThomas Edison

5. History of Laparoscopy
 1901: George Kelling, Dresden,
Saxony (Germany) performed the
1st experimental laparoscopy,
calling it ‘Celioscopy’.
 Kelling insufflated the abdomen of
a dog with filtered air and used a
Nitze cystoscope to look inside.

8. History of Laparoscopy
 1920: Zollikofer discovered the benefit of CO2 gas for insufflation
 1938: Janos Veress developed a spring loaded needle for the
induction of pneumoperitoneum.
 After World War II, the development of fiberoptics represented an
important step forward for endoscopy
 1966: Hopkins rod lens scope & cold light
 1974: Dr Harrith M Hasson, MD working in Chicago, proposed a blunt
mini-laparotomy which permitted direct visualization of the trocar
entrance into the peritoneal cavity. It is popularly known today as
Hasson‘s technique.


In 1970, after becoming the
chairman of Ob/Gyn at the
University of Kiel, his co-workers
demanded that he undergo a
brain scan because, they said,
“only a person with brain damage
would perform laparoscopic
surgery”

10. History of Laparoscopy
 1985: Dr. Muhe (Prof Dr Med - Böblingen, Germany) performed
the first successful laparoscopic cholecystectomy in a human.
However, this was not well publicized until years later. The
German Surgical Society rejected Mühe in 1986 after he reported
that he had performed the first laparoscopic cholecystectomy.

11. Laparoscopy Takes Off
 1988: 1st Lap cholecystectomy in the USA, Surgiport 1st

 1992: The National Institutes of Health Consensus
Conference concludes that laparoscopic cholecystectomy is
now the preferred alternative to open cholecystectomy

12. Definition

17. Principle Differences between
Laparoscopic and Open Surgery




FOR THE PATIENT
Post operative pain related to size of incisionsmaller incisions =less pain.
Less Handling of intestines results in little or no
disturbance of normal function.
Avoidance of the trauma of abdominal wall injury
by the incision allows rapid return to normal
activity
No incision allows early return to more strenuous
activities: driving, lifting, sport etc.

18. Principle Differences between
laparoscopic and open surgery

FOR THE HOSPITAL
Initial capital costs to establish laparoscopic surgery in
the order of Rs 10 - 20 lacs
 Reduced overall costs by shortening of hospital stay e.g.
cholecystectomy reduced from 5 to 1 day, hiatus hernia
repair reduced from 7 to 3 days.

19. Principle Differences between
laparoscopic and open surgery






For the Surgeon
Magnified view often better than obtained via an
incision allows precise dissection.
Altered (but not absent) tactile response
Two dimensional (flat screen) view.
Usually (but not always) longer operating time
Need to develop entirely different operating
technique
Adaptation of principles of open surgery to
laparoscopic surgery.

20. Instruments
 Redesign of instruments for laparoscopic use.
 Instruments for open surgery in general 6 – 10” in length

built around a box joint.
Laparoscopic instruments in general 15 – 18” in length
with an articulated connecting rod between handles and
scissor blades, jaws etc.

21. Equipment Necessary for MAS
Camera
Light Source
Insufflator
TV Monitor
Telescopes
Light Guide Cable
Apart from the
insufflator the system
will work better if all
the components are
from the same
company as one
piece talks to another

22. CAMERA
 These can be single chip or 3 chip.
 CHIP: thois is also called a charged coupled
device in short, CCD.
 These are flat silicone wafers with a matrix, a
grid of minute image sensors called pixels.
 White balance and sometimes black balance
 Sleeve it don’t soak it!!!


23. Light Source
 Halogen or Xenon, cold light but beware can still




burn holes in drapes esp. disposable and burn
patient’s skin if left on the abdomen.
Brightest to darkest measured in units of
decibels.
Automatic illumination, does it talk to the camera
and are the necessary leads plugged in.
Lamp life meter, look at it. Is it nearly out? EBME
keep the spares and they change it.
White balance by making sure white is correct
then all the colours through the spectrum are
correct.

24. Insufflator
 CO2 because this has the same refractive




index as air, so doesn’t distort the image and
is non combustible.
Intraabdominal pressure run between 10 and
13 mmhg.
Use disposable filter and tubing for each
patient.
High flow insufflators (35 litres) output
determined by size of outlet.
Ensure you know how to change a cylinder
and were they are stored.

25. TV Monitors






Usually a 20” screen.
HD is better.
You can use a standard TV but it must be run
through an isolated transformer.
Horizontal resolution is the number of vertical
lines.
Vertical resolution is the number of horizontal
lines
More lines of resolution, better detail of picture.

26. Telescopes
 Come in varying sizes, laparoscopes usually






5mm or 10mm.
Diagnostic 3mm scope available.
Made up of a rod and lens system.
Bundles of fibres, incoherent carry light and
coherent carry image.
Wide range of angles available 0, 30, 45 degree
are fairly standard.
All laparoscopes are autoclavable and can go
through sterilisation, no ultrasonic bath required.
Endo- chameleon- extra long for Bariatric
patients.

27. Light guide Cables






Different diameters
Fibre light cable
Buy auroclavable
Don’t bend to acutely as will break fibres.
Check when you plug them in are all the fibres are okay.
Condensers

28. Instrumentation
 SINGLE USE: breaking the Law if you reuse it




on another patient.
Reusable take apart.
Need an ultrasonic washer to effectively clean
them, not for telescopes.
Don’t put 5mm cannulated instruments into a
bench top autoclave that does not have a
vacuum: vacuum is required to remove all air
form lumen of instrument.
Ports 5 and 10mm are the most common, make
sure the right trocar is in port and is it sharp.

29. Electrosurgery
You should be aware of the following
potential situations:
 Insulation failure of the active electrode.
 Direct coupling of current to other instrumentation
by direct contact.
 Capacitance which may be created by two electrical
conductors separated by an insulator

30. Ultrascision or the Harmonic Scalpel
Electrical generator (the box)
This adjusts the amount of electrical energy
being delivered and monitors performance.
Transducer
This is where electrical energy is converted to
the ultrasonic waves. The frequency is fixed
however the amplitude alters with the power
input. the transducer is located in the hand
piece and is connected to the generator by an
electrical cable.
Dissection Instrument (peripheral hand piece)
A metallic rod is coupled to the transducer and
vibrates at the prescribed frequency (i.e.
55kHz). The tip of the rod contacts with the
surface tissue.

31. Principles of Piezo Electronics
 The ultrasound waves are created by electrical
energy hitting a negatively charged crystal that
vibrates (expands and contracts) at a particular
frequency. These crystals are disc shaped and
made of ferroelectric ceramics. A pair of discs
“coupled” together produce a sinusoidal wave
form. This coupling results in a harmonic
waveform that is of high electroacoustic
efficiency.

32. VERESS NEEDLE
 1938 - Janos Veress, of Hungary, developed the springloaded needle. to perform therapeutic pneumothorax
(TB).
 Made of surgical stainless steel with a single trap valve.
2mm diameter x 80mm length
 It consists of an outer cannula with a bevelled needle
point for cutting through tissues.

33. GAS INSUFFLATION

Controlled pressure insufflation of the peritoneal cavity
is used to achieve the necessary work space for
laparoscopic surgery.

Automatic insufflators allow the surgeon to preset the
insufflating pressure, and the device supplies gas until
the required intra-abdominal pressure is reached.

34. Trocar
 The trocar has a blade with
a shaft and body.
 The body includes a
pointed tip which makes
the initial incision in the
abdominal wall of the
patient.
(Trocar diameters range from
2mm-30 mm)

35. Trocars
 Types:
 Cutting
 Pyramidal
tipped
 Flat blade
 Noncutting
 Pointed conical
 Blunt conical

36. Telescope
 There are three important
structural differences in
telescope available
1. 6 to 18 rod lens system
telescopes are available
2. 0 to 120 degree telescopes
are available
3. 1.5 mm to 15 mm of
telescopes are available

37. Optic cables
 These cables are
made up of a bundle of
optical fibers glass
thread swaged at both
ends.
 The fiber size used is
usually between 10 to
25 mm in diameter.
 They have a very high
quality of optical
transmission, but are
fragile.

38. Dissecting & Grasping Forceps
 Atraumatic
 KELLY atraumatic
 Atraumatic, with hollow jaws
 MANGESHKAR Grasping
Forceps, serrated

39. General instruments
 Reusable three-piece design
 Available in 2 mm, 3 mm,
3.5mm, 5 mm and 10 mm
sizes, with lengths of 20 cm,
30 cm, 36 cm and 43 cm.
 Choice of handle styles.
 Fully rotating 360° sheath.
 No hidden spaces that can
trap operative blood and
tissue debris.

40. Scissors

HOOK SCISSORS, single action
jaws

METZENBAUM SCISSORS,
curved, length of blades 12-17 mm,
widely used as an instrument for
mechanical dissection in
laparoscopic surgery.

STRAIGHT SCISSOR can give
controlled depth of cutting because
it has only one moving jaw.

116. History of Robotics
Leonardo da Vinci
developed one of the
first robots in 1495 – an
armored knight for the
purposes of
entertaining royalty.

117. What Robotics Aimed to Improve in Laparoscopy
 Surgeon operates from a 2D
image
 Straight, rigid instruments
(limited range of motion)
 Instrument tips controlled at a
distance
 Reduced dexterity, precision &
control
 Unsteady camera controlled by
assistant

118. Surgical Robots
AESOP (Automated Endoscopic System for Optimal
Positioning)
- Voice activated mechanical arm
- Steadier than human, never tires
da Vinci®
- FDA approval in 2002
- Laparoscopic instrumentation controlled by the
surgeon, positioned remotely at a console

144. Diabetes
 Considered major public health problem – emerging as a world
wide pandemic. In 1995 ~ 135 million people worldwide
 Currently 240 million, expected to rise to close to 380 million by
2025
 Complications
 Peripheral vascular disease (PVD) accounts for 20-30%
 10% of cerebral vascular accident
 Cardiovascular disease accounts for 50% of total mortality

Effect of laparoscopic Roux-en Y gastric bypass on
type 2 diabetes mellitus.
Ann Surg. 2003 Oct; 238 (4): 467-84
 1160 patients underwent LRYGBP 5-year

period
LRYGBP resulted in significant weight loss
(60% percent of excess body weight loss) and
resolution (83%) of T2DM
 Fasting plasma glucose and HBA1C normalized
(83%) or markedly improved (17%) in all patients
 Patients with the shortest duration and mildest
form of T2DM had a higher rate of T2DM
resolution after surgery
 suggesting that early surgical intervention
is warranted to increase the likelihood of
rendering patients euglycemic

that the bypass of duodenum and jejunum can
directly control type 2 diabetes and
not secondarily to weight loss or treatment of obesity.”

153. THE FUTURE

It has not changed the nature of disease
 The basic principles of good surgery still
apply,including appropriate case selection, excellent
exposure,adequate retraction and a high level
technical expertise
 If a procedure makes no sense with conventional
access, it will make no sense with a minimal access
approach

154. THE FUTURE
 The cleaner and gentler the act of
operation, the less the patient
suffers, the smoother and quicker
his convalescence,the more
exquisite his healed wound.
Berkeley George Andrew Moynihan
