Endoscopy refers to medical procedures that use an endoscope to examine the inside of a body cavity or organ. Some common types of endoscopy include gastroscopy, colonoscopy, laparoscopy, and bronchoscopy. Endoscopy allows physicians to visually examine the interior of organs and tissues, and to perform procedures such as biopsy, polyp removal, and treatment of abnormal growths. Potential risks include infection, bleeding, perforation of organs, and reactions to sedatives used during procedures. Preparation may involve fasting beforehand, and post-procedure recovery typically involves monitoring for complications. Endoscopy is used to diagnose conditions like ulcers, inflammation, tumors, and to investigate unexplained symptoms.

7. ENDOSCOPIC PROCESS
 ENDOSCOPIC PROCESS
 The endoscope also has a channel through which surgeons can manipulate tiny
instruments, such as forceps, surgical scissors, and suction devices.
 A variety of instruments can be fitted to the endoscope for different purposes.
 A surgeon introduces the endoscope into the body either through a body opening,
such as the mouth or the anus, or through a small incision in the skin.

8. PROCEDURE
 Fast before the endoscopy.
 Typically need to stop eating solid food for eight hours and stop drinking liquids
for four hours before your endoscopy.
 This is to ensure your stomach is empty for the procedure.
 Stop taking certain medications. You'll need to stop taking certain blood-thinning
medications in the days before your endoscopy, if possible. Blood thinners may
increase your risk of bleeding if certain procedures are performed during the
endoscopy. If you have ongoing conditions, such as diabetes, heart disease or
high blood pressure, your provider will give you specific instructions regarding

12. GASTROSCOPY

13. GASTROSCOPY

14. CAUSES
 widen your food pipe (oesophagus) if it’s too narrow and causing pain or
difficulties when you swallow
 stop bleeding inside your stomach or oesophagus
 remove growths
 with feeding if you’re unable to eat normally (a gastroscopy can help doctors
place a feeding tube into your stomach)
 Checking for cancer

15. PREPARATION
 You should avoid eating or drinking for 4-6 hours before the test. The stomach
needs to be empty. (Small sips of water may be allowed up to two hours before
the test.)
 If you have a sedative you will need somebody to accompany you home.
 Advice about medication which may need to be stopped before the test.

16. RISK FACTORS
 Accidental tearing of a blood vessel in the oesophagus or stomach leading to
bleeding
 Internal bleeding that can further result in the elimination of black stools with a
rough, tar-like texture
 Pain in the neck, chest and stomach
 Discomfort and aching while swallowing food
 Breathing problems
 Fever
 Nausea and vomiting

17. ERCP
 Endoscopic retrograde cholangiopancreatography, or ERCP, is a procedure to
diagnose and treat problems in the liver, gallbladder, bile ducts, and pancreas. It
combines X-ray and the use of an endoscope—a long, flexible, lighted tube.

18. ERCP

19. ERCP USES
 pancreatic ducts may be narrowed or blocked due to:
 • tumors
 • gallstones that form in the gallbladder
 and become stuck in the ducts
 • inflammation due to trauma or illness, such as pancreatitis
 • infection
 • Dysfunction of valves in the ducts, called sphincters,
 • scarring of the ducts (sclerosis),
 • Pseudo-cysts—accumulations of fluid and tissue debris

20. USES
 cardiopulmonary,
 neurologic,
 or cardiovascular status;
 and existing bowel perforation.
 • Structural abnormalities of the esophagus, stomach, or small intestine may be
relative contraindications for ERCP.
 • An altered surgical anatomy.
 • ERCP with sphincterotomy or ampullectomy is relatively contraindicated in
coagulopathic patients.

21. PREPARATION OF PATIENT BEFORE ERCP
 • The upper GI tract must be empty.
 Generally, no eating or drinking is allowed 8 hours before ERCP.
 • Smoking and chewing gum are also prohibited during this time.
 • Current medications may need to be adjusted or avoided.
 Most medications can be continued as usual.
 • Removal of any dentures, jewelry, or contact lenses before having an ERCP.

22. PROCEDURE
 • A plastic catheter or cannula is inserted through the ampulla, and radiocontrast
is injected into the bile ducts and/or pancreatic duct. Fluoroscopy is used to look
for blockages, or other lesions such as stones.
 • When needed, the opening of the ampulla can be enlarged (sphincterotomy)
with an electrified wire (sphincterotome) and access into the bile duct obtained so
that gallstones may be removed or other therapy performed.

23. PROCEDURE
 A Plastic catheter or cannula is inserted through the ampulla, and radiocontrast is
injected into the bile ducts and/or pancreatic duct. Fluoroscopy is used to look for
blockages, or other lesions such as stones. • When needed, the opening of the
ampulla can be enlarged (sphincterotomy) with an electrified wire
(sphincterotome) and access into the bile duct obtained so that gallstones may be
removed or other therapy performed.

24. AFTER THE PROCEDURE
 AFTER THE PROCEDURE
 • Patients are monitored in the endoscopy area for 1-2 hours until the effects of
the sedatives have worn off & observed for complications.
 • Eating or drinking is allowed if the throat is no longer numb and are able to
swallow without choking.
 • If a gallstone was removed or placed a stent during the test, the patient is made
to stay in the hospital

25. COMPLICATIONS
 Undergoing ERCP can lead to complications involving
 infection,
 bleeding,
 perforation,
 or inflammation of the pancreas (pancreatitis).

26. Proctosigmoidoscopy
 Proctosigmoidoscopy (Proctoscopy,Sigmoidoscopy) is an internal examination of
the lower large bowel (colon), using an instrument called a sigmoidoscope. The
sigmoidoscope is a small camera attached to a flexible tube. It is inserted into the
colon to examine the rectum, and the sigmoid and descending portions of the
colon.

27. PROCTOSIGMOIDOSCOPY

28. INDICATIONS
 diagnose a disease in rectum or anus, including cancer
 find the cause of bleeding from the rectum
 diagnose hemorrhoids
 remove a sample of tissue for testing, called a biopsy
 find and remove polyps and other abnormal growths
 monitor rectal cancer after surgery or other treatments

29. RISK FACTORS
 infection
 belly pain
 a tear in the rectum (this is rare)

30. PROCEDURE
 A gastroenterologist (a specialist in diseases of the digestive system) will gently
insert a gloved and lubricated finger (or fingers) into the rectum to check for
blockage and to dilate the anus. This is called a digital rectal examination.
 Following the digital rectal exam, the sigmoidoscope will be inserted. This flexible
fiberoptic tube is about 20 inches long.
 The scope is gently advanced into the colon. Air is introduced into the scope to
aid in viewing. The air may cause the urge to defecate. As the sigmoidoscope is
slowly removed, the lining of the bowel is carefully examined. A channel in the
scope allows for the passage of forceps for biopsies or other instruments for
therapy.

31. Proctosigmoidoscopy USES
 Inflammatory bowel disease
 Bowel obstruction
 Colon cancer
 Colon polyps
 Diverticulosis (the presence of abnormal pouches on the lining of the intestines)
 Causes of diarrhea
 Causes of abdominal pain

32. COMPLICATIONS
 Perforation,
 bleeding,
 abdominal discomfort
 and cardiac arrhythmias

33. Flexible Sigmoidoscopy
 Flexible sigmoidoscopy is a procedure wherein a sigmoidoscope is inserted
through the anus, the distal colonic mucosa (up to 60 cm from the anal verge) is
examined, and any diagnostic or therapeutic maneuvers performed, as needed.
 A sigmoidoscopy is a diagnostic test used to check the sigmoid colon, which is the
lower part of your colon or large intestine. This section of your colon is close to
your rectum and anus.

34. FLEXIBLE SIGMOIDOSCOPY

35. Flexible Sigmoidoscopy Indications
 Flexible Sigmoidoscopy Indications:
 Routine screening of adults over age 50
 Evaluation of suspected distal colonic disease when there is no indication for
colonoscopy
 Inflammatory bowel disease
 Chronic diarrhea
 Pseudomembranous colitis
 Radiation colitis Sigmoid volvulus Foreign body removal Lower GI
bleeding

36. INDICATIONS
Foreign body removal
 Sigmoid volvulus
Lower GI bleeding
Evaluation of the colon in conjunction with a barium enema

37. BENEFIT
 The flexible sigmoidoscopy procedure usually takes between five and 15 minutes.
 It's done by a specially trained doctor or nurse. You don't usually need to have an
anaesthetic or sedative for a flexible sigmoidoscopy. The procedure can be
uncomfortable at first, but it doesn't usually hurt.

38. COLONOSCOPY
 A colonoscopy (koe-lun-OS-kuh-pee) is an exam used to look for changes — such
as swollen, irritated tissues, polyps or cancer — in the large intestine (colon) and
rectum. During a colonoscopy, a long, flexible tube (colonoscope) is inserted into
the rectum.

46. RECOMMENDED FREQUENCY
 Men and Woman at age 50
 • Repeated at 10 year intervals
 • More frequent if other risk factors present
 • Family history, IBS

47. SMALL BOWEL ENTEROSCOPY
 A small bowel enteroscopy allows a physician to navigate the entire small bowel
from either an oral or rectal approach, enabling them to perform both diagnostic
and therapeutic techniques within the small bowel without the need of an open
surgical procedure.

48. SMALL BOWEL ENTEROSCOPY

49. ENDOSCOPIC ULTRASOUND
 Endoscopic ultrasound (EUS) is a minimally invasive procedure to assess diseases
of the digestive (gastrointestinal) tract and other nearby organs and tissues.
Endoscopic ultrasound combines the use of a thin, flexible tube (endoscope)
inserted into the gastrointestinal tract and a device that uses sound waves to
create images (ultrasound).

50. Endoscopic ultrasound

51. PROCEDURE
 The high-frequency sound waves produce detailed images of the digestive tract
and surrounding organs and tissues, including the lungs, pancreas, gall bladder,
liver and lymph nodes.
 An endoscopic tube may also have a small needle to remove fluid or tissue
samples (biopsy) for examination in a lab. This procedure is called EUS-guided
fine-needle aspiration or EUS-guided fine-needle biopsy. Other EUS-guided
procedures can be used to drain fluid from a lesion or inject a drug at a specific
site.

52. RADIOLOGICAL INVESTIGATIONS
 Barium swalow
 Upper gastrointestinal series
 Barium enema

53. BARIUM SWALLOW
 A barium swallow, also called an esophagogram, is an imaging test that checks for
problems in your upper GI tract. Your upper GI tract includes your mouth, back of
the throat, esophagus, stomach, and first part of your small intestine. The test uses
a special type of x-ray called fluoroscopy. Fluoroscopy shows internal organs
moving in real time. The test also involves drinking a chalky-tasting liquid that
contains barium. Barium is a substance that makes parts of your body show up
more clearly on an x-ray.

54. BARIUM SWALLOW

55. USES
 Ulcers
 Hiatal hernia, a condition in which part of your stomach pushes into the
diaphragm. The diaphragm is the muscle between your stomach and chest.
 GERD (gastroesophageal reflux disease), a condition in which contents of the
stomach leak backward into the esophagus
 Structural problems in the GI tract, such as polyps (abnormal growths) and
diverticula (pouches in the intestinal wall)
 Tumors

56. INDICATIONS
 Trouble swallowing
 Abdominal pain
 Vomiting
 Bloating

57. PROCEDURE
 You may need to remove your clothing. If so, you will be given a hospital gown.
 You will be given a lead shield or apron to wear over your pelvic area. This protects the area from
unnecessary radiation.
 You will stand, sit, or lie down on an x-ray table. You may be asked to change positions during the
test.
 You will swallow a drink that contains barium. The drink is thick and chalky. It's usually flavored
with chocolate or strawberry to make it easier to swallow.
 While you swallow, the radiologist will watch images of the barium traveling down your throat to
your upper GI tract.
 You may be asked to hold your breath at certain times.
 The images will be recorded so they can be reviewed at a later time.
 Will I need to do anything to prepare for the test

58. UPPER GASTROINTESTINAL SERIES
 An upper gastrointestinal series (UGI) is a radiographic (X-ray) examination of the
upper gastrointestinal (GI) tract. The esophagus, stomach, and duodenum (first
part of the small intestine) are made visible on X-ray film by a liquid suspension.
This liquid suspension may be barium or a water-soluble contrast.

59. UPPER GASTROINTESTINAL SERIES

60. CONT
 An upper gastrointestinal series, also called a barium swallow, barium study, or
barium meal, is a series of radiographs used to examine the gastrointestinal tract
for abnormalities.

61. INDICATIONS
Difficulty swallowing
Chest and abdominal pain
Reflux (a backward flow of partially digested food and digestive juices)
Unexplained vomiting
Severe indigestion
Blood in the stool (indicating internal GI bleeding)

62. CONTRAINDICATION
 Recently operated patient . •
 Complete large bowel obstruction. •
 History/suspicion of aspiration . •
 Fistulous communication with any organ other than parts of GIT .
 • Recent biopsy of GIT , as barium granuloma formed at biopsy site.

63. complications
 Leakage of Ba from unsuspected perforation leading to Ba peritonitis
 • Aspiration of stomach contents (due to buscopan)
 • Barium impaction (partial bowel obstruction to complete bowel obstruction)
 • Barium appendicitis if Ba impacted in appendix
 • Adverse effects of pharmacological agents used.

64. BARIUM ENEMA
 A barium enema is an X-ray exam that can detect changes or abnormalities in the
large intestine (colon). The procedure is also called a colon X-ray. An enema is the
injection of a liquid into your rectum through a small tube.

65. BARIUM ENEMA

66. INDICATIONS
 abdominal pain
 blood in your stools
 a change in your bowel movements
 Crohn’s disease
 chronic diarrhea
 colorectal cancer
 diverticulitis
 irritable bowel syndrome
 polyps
 rectal bleeding
 a twisted loop of the bowels (volvulus)
 ulcerative colitis

67. PREPARATION
 Your doctor will ask you to cleanse your bowels the night before your test. This
may include using laxatives or taking an enema at home.
 You shouldn’t eat anything after midnight the night before your procedure. On the
day of the procedure, you can drink clear liquids, such as water, tea, juice, or broth.
This is to ensure that your colon is clear of any stool, which could show up in the
X-ray images. Tell your doctor if you’ve been having problems with your bowel
movements prior to the test.

68. PROCEDURE
 A well-lubricated enema tube is gently inserted into the rectum. Barium is injected
through this tube into the colon and rectum. A small balloon at the end of the
tube is inflated to keep the barium inside. X-rays are taken.

69. RISK FACTORS
 inflammation of the tissues around your colon
 obstruction of your gastrointestinal tract
 a perforated colon
 a tear in your colon wall

70. ABDOMINAL ULTRASOUND
 Abdominal ultrasound is a type of imaging test. It is used to look at organs in the
abdomen, including the liver, gallbladder, spleen, pancreas, and kidneys.

71. ABDOMINAL ULTRASOUND

72. CT SCAN
 Computed tomography is commonly referred to as a CT scan. A CT scan is a
diagnostic imaging procedure that uses a combination of X-rays and computer
technology to produce images of the inside of the body. It shows detailed images
of any part of the body, including the bones, muscles, fat, organs and blood
vessels.

73. CT SCAN

74. USES
 Diagnose cancers.
 CV disease.
 Infectious disease.
 Appendicitis.
 Trauma. And
 Muscular-skeletal disorders.

75. PROCEDURE
 CT scan: Equipment Large box-like machine with hole in the middle. Pt. lies on
narrow table that slides in and out of this hole. X-ray tube and electronic x-ray
detectors rotate around you (gantry).
 Computer processes the information and is operated by a technologist who
works scanners and monitors the exam.

76. ADVANTAGES
 Advantages to CT Desired image detail is obtained. Fast image rendering. Filters
may sharpen or smooth reconstructed images. Raw data may be reconstructed
post-acquisition with a variety of filters.

77. DISADVANTAGES
 Multiple reconstructions may be required if significant detail is required from areas
of the study that contain bone and soft tissue. Need for quality detectors and
computer software. X-ray exposure.
