Things worth knowing about "Endoscopy"
Endoscopy is a medical procedure in which a small camera is used to examine the inside of the body. It helps diagnose and treat many conditions.
What is Endoscopy?
Endoscopy is a diagnostic and therapeutic medical procedure in which the interior of the body – including hollow organs and body cavities – is examined using a specialised optical instrument called an endoscope. The endoscope is a thin, flexible or rigid tube equipped with a light source and a miniature camera. The images are transmitted in real time to a monitor for the physician to evaluate.
Endoscopy is used across a wide range of medical specialties, including gastroenterology, pulmonology, gynaecology, urology, and ear, nose and throat (ENT) medicine.
Types of Endoscopy
Depending on the area of the body being examined, different types of endoscopy are used:
- Gastroscopy: Examination of the oesophagus, stomach, and duodenum (upper gastrointestinal endoscopy)
- Colonoscopy: Examination of the large intestine (colon)
- Bronchoscopy: Examination of the airways and lungs
- Cystoscopy: Examination of the urinary bladder
- Laparoscopy: Examination of the abdominal cavity and organs
- Arthroscopy: Examination of joints
- Colposcopy / Hysteroscopy: Examination of the cervix or uterine cavity
- Laryngoscopy / Rhinoscopy: Examination of the larynx or nasal cavity
When is Endoscopy Used?
Endoscopy may be recommended for a variety of clinical reasons:
- Investigation of unexplained symptoms such as abdominal pain, difficulty swallowing, or gastrointestinal bleeding
- Cancer screening, for example colonoscopy from the age of 50
- Collection of tissue samples (biopsy) for laboratory analysis
- Therapeutic interventions such as polyp removal, stopping bleeding, or dilating narrowed passages
- Monitoring of known conditions such as Crohn's disease or peptic ulcers
Preparation and Procedure
Preparation depends on the type of endoscopy being performed. For a colonoscopy, the patient must undergo bowel cleansing the day before. For a gastroscopy, the patient must fast for several hours beforehand. In many cases, a light sedative or anaesthetic spray is offered to ensure comfort during the procedure.
During the examination, the physician carefully guides the endoscope into the body and examines the mucosal lining and structures on the monitor. Biopsies or therapeutic measures can be carried out during the same procedure if needed.
Risks and Side Effects
Endoscopy is generally considered a safe procedure, but like any medical intervention, it carries some risks:
- Minor bleeding, especially after biopsy or polyp removal
- Rare risk of organ injury (perforation)
- Reactions to sedation medication
- Infection (very rare when proper hygiene protocols are followed)
Patients are fully informed about the benefits and risks of the procedure before it is carried out.
Aftercare
Following an endoscopy with sedation, patients must not drive or operate machinery due to the residual effects of the sedative. Mild bloating or a feeling of pressure after a colonoscopy is normal and resolves quickly. Results are usually discussed with the patient shortly after the procedure.
