Laparoscopy is an operation performed in the abdomen or pelvic area using small incisions, often less than 1.5 cm, with the assistance of a Laparoscopic camera, typically for gallbladder, colon, kidney, and other procedures. Before, if an operation had to be conducted in the belly, doctors had to cut open the area, hence the name laparotomy.

Fine Needle Aspiration Cytology (FNAC) is a simple, quick and inexpensive method that is used to sample superficial masses like those found in the neck and is usually performed in the outpatient clinic.
Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

2. INTRODUCTION
During an endoscopy, the doctor inserts a tool called an endoscope into a person’s body.
Most endoscopes are thin tubes with a powerful light and tiny camera at the end.
The endoscope’s length and flexibility depend on the part of the body the doctor needs to
see.
For example, a straight endoscope helps a doctor look at joints. Meanwhile, a flexible one
helps a doctor view the inside of the colon.
3. ENDOSCOPY
Endoscopy is a procedure that allows a doctor to view the inside of a person’s body. Doctors use it to
diagnose diseases in the following parts of the body:
Esophagus
Stomach
Colon
Ears
Nose
Throat
Heart
Urinary tract
Joints
Abdomen
4. FUNCTIONS
Endoscopes were first developed to look at parts of the body that couldn’t be seen any
other way.
1. To prevent and screen for cancer
2. To find cancer early
3. Looking for causes of symptoms
4. Looking at problems found on imaging tests

11. OTHER TOOLS USED DURING AN
ENDOSCOPY
Typically, an endoscope has a channel through which the doctor can insert tools. These
tools collect tissue or provide treatment.
Types of tools include:
1.Flexible forceps: These tong-like tools take a tissue sample.
2.Biopsy forceps: These remove a tissue sample or a suspicious growth.
3.Cytology brushes: These take cell samples.
4.Suture removal forceps: These remove stitches inside the body

14. ENDOSCOPE CONSIST OF:
An endoscope consists of the following:
• A lighting system (to illuminate inner cavities);
• An image transmission system (to send an image outside of the body by means of an
objective lens which focuses it on aligned image guide fibers or a CCD)
• Channels for air (to inflate the body cavity and for suction to remove fluids) and water (to
wash the objective lens and to introduce biopsy forceps)
• A bending mechanism to deflect the endoscope tip.
• An Endoscopy monitor to display the examinations, surgical procedures.

17. SAFETY CONCERNS RELATED TO THE
EQUIPMENT
• Bite guard for the endoscopes
• For the patient safety
• The concerned endoscopes are Sterilized before insertion
• Reprocessing
18. Reprocessing
To ensure flexible endoscopes are safe for patient use, all staff involved in
reprocessing this equipment must understand and consistently follow a number of
steps which have been distilled down to seven essential steps. Ensuring
adherence to these steps requires a complete and effective reprocessing
program. These recommendations apply to all settings where endoscopic
procedures are performed and where endoscopes are reprocessed.
19. Pre-Cleaning
a. Pre-Clean flexible endoscopes and reusable accessories by following the device
manufacturer’s instructions for use (IFU).
Perform pre-cleaning immediately following completion of the endoscope procedure to help
prevent the formation of biofilm.
Leak-Testing
a. For endoscopes that require leak testing, perform the leak test using manufacturer’s IFU
after each use and prior to manual cleaning. Leak testing detects damage to the external
surfaces and internal channels of the endoscope that can lead to inadequate disinfection
and further damage of the endoscope.
Manual Cleaning
a. Perform meticulous manual cleaning including brushing and flushing channels and ports
consistent with the manufacturer’s IFU before performing high-level disinfection (HLD) or
sterilization. Perform manual cleaning within the timeframe specified in the manufacturer’s
IFU. Manual cleaning is the most critical step in the disinfection process since residual
organic material can reduce the effectiveness of HLD and sterilization.
20. Visual Inspection
a. After manual cleaning, visually inspect the endoscope and its accessories. Visual
inspection provides additional assurance that the endoscope and its accessories are clean
and free of defects. Complex devices such as flexible endoscopes may require the use of
lighted magnification or additional methods to assist with the inspection process.
Disinfection or Sterilization
a. Following cleaning and visual inspection perform HLD or sterilization in accordance with
the manufacturer’s IFU. Carefully review and adhere to the endoscope manufacturer’s
reprocessing instructions and to the IFU for chemicals or sterilants and any equipment
(e.g., automated endoscope reprocessors) used for reprocessing to help ensure that
effective disinfection occurs.
21. Storage
a. After reprocessing is complete, store endoscopes and accessories in a manner that
prevents recontamination, protects the equipment from damage, and promotes drying.
Store processed flexible endoscopes in a cabinet that is either:
i. of sufficient height, width, and depth to allow flexible endoscopes to hang vertically
without coiling and without touching the bottom of the cabinet OR
ii. designed and intended by the manufacturer for horizontal storage of flexible
endoscopes.
Documentation
a. Maintain documentation of adherence to these essential steps each time an endoscope
is reprocessed. Documentation is essential for quality assurance purposes and for patient
tracing in the event a look back is necessary.

24. ENDOSCOPE EQUIPMENT MAINTENANCE
Proper Handling of Endoscope
• Avoid touching the eyepiece lens or the objective lens to prevent contamination. Even the
smallest dust or dirt or fingerprint may cause an undesirable image.
Light Source and Monitor Maintenance
• Light Source and Monitor Maintenance
• Check the image quality on the display to ensure the camera is 100% dust or dirt free. The
image or display should be clear, with no blurring, distortion or discoloration.
• Perform a white balance test to ensure the clearest display.
25. SAFETY AND PRECAUTION
• Calibration of the equipment
• Leakage test
• Bite guard is used to prevent any gag reflex by the patients to make sure there is no
damage to the equipment.
• Sterilizer- machine is put on the sterilizer for 60 minutes.
