Medical technology has come a long way in making internal diagnoses safer, faster, and more accurate. One of the most important diagnostic tools in modern medicine is endoscopy—a minimally invasive procedure that allows doctors to visually examine internal organs without surgery. Whether you’re undergoing this procedure soon or just want to learn more, this blog covers everything you need to know about endoscopy.
What is Endoscopy?
Endoscopy is a non-surgical medical procedure used to examine the interior of a hollow organ or cavity in the body using an instrument called an endoscope. This flexible tube is equipped with a light and camera, enabling real-time visualization on a monitor.
Endoscopies are primarily used for diagnostic and therapeutic purposes. They can detect abnormalities, collect biopsies, remove polyps, or even treat bleeding sites—all without open surgery.
Why is an Endoscopy Performed?
Doctors may recommend an endoscopy for various reasons, particularly to investigate symptoms such as:
Persistent stomach pain
Gastrointestinal bleeding (vomiting blood or black stool)
Suspected ulcers, tumors, or inflammation
It is also used to:
Perform biopsies
Remove foreign objects
Treat blockages or bleeding
Monitor chronic diseases like Crohn’s disease or ulcerative colitis
Types of Endoscopy
There are different types of endoscopy based on the organ or body part being examined:
1. Upper GI Endoscopy (Gastroscopy)
Used to view the esophagus, stomach, and duodenum. Commonly used for diagnosing GERD, ulcers, or stomach cancer.
2. Colonoscopy
Used to examine the large intestine (colon) and rectum. Commonly used for screening for colon cancer or investigating lower GI symptoms.
3. Sigmoidoscopy
Focuses only on the sigmoid colon and rectum. Often used as a quicker screening method for colorectal disease.
4. Bronchoscopy
Used to inspect the lungs and airways.
5. Cystoscopy
Used to examine the bladder and urethra.
6. Hysteroscopy
Used to visualize the uterus in gynecological procedures.
7. Endoscopic Ultrasound (EUS)
Combines endoscopy and ultrasound to obtain images of internal organs such as the pancreas and gallbladder.
8. Capsule Endoscopy
Involves swallowing a capsule with a mini camera to take images of the digestive tract.
Preparing for an Endoscopy
Proper preparation is crucial for the success and accuracy of an endoscopy. Here are some general preparation guidelines:
Before the Procedure
Fasting: You’ll likely need to fast for 6–8 hours before the procedure.
Bowel Prep: For colonoscopy or sigmoidoscopy, a bowel-cleansing solution may be prescribed to empty the intestines.
Medication Adjustment: Inform your doctor about medications, especially blood thinners, insulin, or heart medications.
Allergy Alert: Let your doctor know if you’re allergic to anesthesia or sedatives.
Consent and Instructions
You’ll be asked to sign a consent form. Your doctor will explain the procedure, risks, and any specific instructions based on your condition.
What Happens During an Endoscopy?
Most endoscopy procedures follow a similar process:
At the Centre
You’ll lie down in a comfortable position, and vital signs will be monitored.
Sedation
A sedative or anesthesia will be administered intravenously to help you relax or sleep during the procedure.
Insertion of Endoscope
The doctor will gently insert the endoscope through the mouth, nose, or rectum depending on the type of endoscopy.
Visual Inspection and Intervention
Images from the camera will be viewed on a screen. Tools may be passed through the scope to collect biopsies or perform treatments.
Duration
The procedure usually takes 15–60 minutes.
What to Expect After an Endoscopy
Recovery Time
You’ll be monitored in a recovery room for about an hour. Due to sedation, you’ll need someone to drive you home.
Post-Procedure Effects
Minimal discomfort
Rarely, slight bleeding if a biopsy was done
These usually resolve within a day.
Understanding Endoscopy Results
Normal Results
Indicate no abnormalities in the inspected organ. This helps rule out serious conditions.
Abnormal Results
Could indicate:
Ulcers
Polyps
Infections
Structural abnormalities (like strictures)
If a biopsy was taken, the results may take a few days to come back. Your doctor will discuss further steps if any issues are detected.
Risks and Complications of Endoscopy
Though endoscopy is considered safe, some rare complications include:
Bleeding (especially after biopsy or polyp removal)
Perforation (tear in the organ wall)
Infection
Reaction to sedatives (e.g., respiratory depression)
Sore throat or bloating
Always follow post-procedure instructions to minimize these risks.
Advantages of Endoscopy
Minimally invasive
Quick recovery time
Highly accurate diagnosis
Ability to treat and diagnose simultaneously
No need for large surgical incisions
Reduces hospital stay and costs
Endoscopy vs Imaging: Why It’s Better in Some Cases
Unlike CT scans or MRIs, endoscopy provides direct visualization of internal surfaces. Plus, it enables real-time biopsy or intervention, which imaging alone can’t do. That’s why it’s preferred for conditions like ulcers, celiac disease, and early-stage cancers.
Who Needs an Endoscopy?
You may benefit from an endoscopy if:
You have persistent GI symptoms
You have family history of GI cancers
You’re over 45 with new onset of digestive issues
You need a follow-up of a known condition like ulcers or IBD
Your doctor wants a tissue biopsy for confirmation
Endoscopy in Children and Elderly
Endoscopy is safe and effective in both children and elderly with necessary precautions. Pediatric endoscopies are often done for chronic vomiting, bleeding, or foreign body ingestion. In elderly patients, it’s vital to monitor for sedation side effects.
