Laparoscopic surgery, also known as minimally invasive surgery, involves using small incisions and instruments to operate on the abdominal organs through the abdominal wall. Key aspects include insufflating the abdominal cavity with carbon dioxide gas to provide space to see and operate, inserting telescopes and instruments through ports, and performing the actual operation using long narrow instruments. Advantages over open surgery include smaller incisions, less pain, quicker recovery, and improved cosmesis. Complications can still occur but are less common than with open surgery. Today laparoscopic techniques are used for many abdominal operations.
This presentation of introduction of laparoscopic surgery made by Dr. R.K. Mishra Director and chief surgeon World Laparoscopy Hospital. Dr. Mishra in this presentation has explained present pas and future of laparoscopic surgery. Laparoscopy is a surgical procedure which uses a special surgical instrument called a laparoscope to look inside the body, or to perform certain operations. World Laparoscopy Hospital is the center of excellence for laparoscopic and da vinci robotic surgery training and considered as one of the best institute in the world.

This presentation will help u know with the history,present and coming up trends in laparoscopy .Also it is an acquaintance presentation regarding laparoscopy.
This PPT is mainly on the Basic Principles of Minimal Invasive Surgery. The Final Yr. MBBS - Students shouls know the principles of Lap. surgery before going to their internship.
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 struct uresIncludes 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.

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
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.
We actually do not know what is there stored for us, but we believe that laparoscopy is trending towards advancement and nano and robotic technology is going to replace in future.
3D cameras have come into existence and various newer technologies are being invented.

Minimally invasive/accessed surgery comprises of robotic and non robotic surgery. Non robotic surgery includes laparoscopy, endoscopy, arthroscopy and etc.
Significant improvements in the surgical approaches and management of diseases have been made in the last century since the advent of antibiotics and aseptic surgical techniques. A major revolution has happened in the last 25 years, as the focus has shifted to minimally invasive surgery and subsequently to robotic assisted surgery. The da Vinci system is by far the most successful surgical robot in use today.
Laparoscopic surgery, also called minimally invasive surgery (MIS)/ bandaid surgery / keyhole surgery, is a modern surgical technique which includes operations performed far from their location through small incisions(usually 0.5–1.5 cm) to the other part of the body.
Various advantages are seen by the patient with laparoscopic surgery versus the open procedure. Pain and draining are lessened because of smaller entry points and recuperation times are shorter. The key element in laparoscopic surgery is the use of a laparoscope, a long fiber optic cable system which allows screening of the affected area by twisting the cable from far-away, but more easily accessible location.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

3. I. What is laparoscopic surgery?
II. Advantages
III. Contraindications
IV. Side effects
V. Complications
4. -Any surgical procedure requires two basic
steps
1-Access and exposure of the part to be
operated
2-The actual operative steps
-In traditional surgery we do access and
exposure through incision in abdominal wall by
blades and obtain a wide field by retractors with
a good light on the operative field
5. -In laparoscopic surgery to do access and
exposure we have to create a space to see
and operate, this space will be created by
insufflation of peritoneal cavity by
co2(pneumoperitonium) which done by using
of verress needle
-To see the operative part we have to insert a
telescope with optic fiber light source through
a small port
-By a camera attached to the eye piece of the
telescope which convert the image of
telescope to a video signal transmitted via a
cable to video processing unit which convert
6. -the actual operation in laparoscopic surgery
all instruments should be long and narrow to
go through narrow tubes(cannula) which are
fixed to small ports at abdominal wall
-Laparoscopic instruments include
- Trocars, cannulas, reducers
,graspers(toothed, non toothed, locked ,non
locked, connected to dithery and non
connected),dissecting hooks and
spatula,scissors,needle holder and retractors.
All these instruments are available in 5mm
and 10mm
-Suction and irrigation unit
14. - It is called the minimal access surgery and all
the advantages come from minimal wounds
-Small wound size decreases infections,
dehesience,bleeding,incisional hernia, nerve
cutting, post operative pain and, psychic wound
trauma
-It improve post operative mobility
-It is cosmetic for patient particularly female
15. -Advanced cardiopulmonary insufficiency
-Risks of anesthesia
-Adhesions due to multiple previous operations
-Peritonitis
-Ileus
-Portal hypertension
-Coagulopathy
-Morbid obesity
-Thin physique(kyphosis)
-General inoperability
16. -Increase intraabdominal pressure which gives
rise to
1-Decrease respiration by decreasing
diaphragmatic movement
2-Decrease venous return
3-Decrease cardiac out put
-Acidosis due to co2 absorption
17. -General complications as in traditional surgery
-Specific complications as
1-Perforated viscous
2-Injury of big vessels
3-Injury to viscous by diathermy
19. Gynaecologists used purely optical
telescope for illumination and
visualisation with one hand on the
telescope without assisted Then
television camera that give an
adequate image so it allow the
assistant to have the same view as
surgeon Then
the assistant hold the camera
allowing the surgeon to operate with
tow hands
20.
21.
22. Today laparoscopic surgery for the
following operations cholecystectoy,
appendectomy,splenectomy, node
biopsy, coloctomy, rectopexy,hernial
repair, fundoplication for gastro-
oesophageal reflux diseases,dudenal
perforation,
adrenalectomy,nephrectomy for doner
transp.
23. ONE port for lap cho .
GASLESS lap cho. By
abdominal wall lifting
.Lap. Cho. Through
vagina
24. Robotics is rapidly developing in
surgery It is means that a machine
acting autonomously as a remote
extension of the surgeon minimal
invasive surgery (laparoscopic
surgery)is a form of telemanipulation
because the surgeon is physically
separated from the workspace so
telerobotics is an obvious tool to
extend the surgeon capabilities .
25. The goal is to restore the tactile cues and
intuitive dexterity of the surgeon which are
dim shed by minimal invasive surgery
several passive mechanical devices primarily
used to hold the telescope as assistants to
the surgeon then one master slave system
has tow primary components which act
surgeon arms to hold and manipulates the
detachable surgical instruments those pencil
sized with tiny electromechanically controlled
26.
27.
28. Software is used to translate large
natural movements to extremely
precise micro movements surgeons
can immediately observe the
instruments in the patient`s body
respond to the movements of their
hands on the handles as if they were
performing the operation directly this
a void the need for the reversed
counterintuitive motion used in
minimally invasive surgery
29. The robotic and computer
technologies can sense the surgeon`s
hand movement and scales it to seam
Lessly and electronically translate the
surgeon`s hand movements into
precise micro movements and filter
out any tremors in the surgeo`s hands
The robot can not move by itself or
decide for itself but requires the
surgeons
30.
31. The name of robot is Leonard da vinci
The advantages of robot surgery are :
Invisible scaring ,no post operative pain
,minimal blood loss ,decrease the
complication ,shorter hospital stay
,quicker recovery.
For the surgeons can perform the
surgery from the console and then
over seas
