Colonoscopy – a procedure that uses a special tube (speculum) introduced through the rectum to look inside the entire large intestine (the colon). This is performed with a narrow, flexible instrument known as a colonoscope, measuring between 130 and 200 cm. The visual tracks in the colonoscope make it possible to present images from inside the gastrointestinal tract at an adequate magnification level on a colour monitor. The purpose of the examination is to assess the mucosal surface of the large intestine. With the use of additional instruments, it is possible to collect mucosal specimens for histopathological examination and perform endoscopic procedures, which often help patients avoid surgical interventions.
Information about your health that must be reported to the physician performing the examination:
- aggravation of the ischemic heart disease
- arterial hypertension
- aortic aneurysm
- breathlessness at rest
- susceptibility to bleeding (haemorrhagic diathesis)
- menstrual bleeding on the day of the examination
- allergy to drugs

How to prepare for the examination

Examination under general anaesthesia
- The colonoscopic examination can be performed under general anaesthesia. Upon intravenous administration of an anaesthetic, the patient falls asleep for several minutes and wakes up once the procedure is over. It is a shallow anaesthesia which does not require tracheal intubation.
- If your colonoscopic examination is scheduled for the late morning hours, apply a one-day model, beginning from around 4.00 pm and taking the second portion of the preparation at around 8.00 pm.
After the examination
- After the examination, you can experience flatulence and intestinal spasms caused by the air introduced into the intestine during the procedure. This sensation subsides after breaking winds.
- When a discomfort appears - flatulence, spasmodic abdominal pains – you should take Espumisan (3x2 tab.) or No-Spa (3x1 tab.).
- After the examination, it is recommended that you resume your daily diet. If the examination is performed under general anaesthesia, an easily-digestible food can be consumed from the moment indicated by the anaesthesiologist.
- Resign from driving vehicles or operating other moving machines for at least 12 hours after general anaesthesia, because your physical and mental fitness may be impaired.
- If your colonoscopic examination was performed under general anaesthesia, you will remain under supervision for 1-2 hours. You will need somebody to take you home after the procedure. If you do not remember the instructions you received after the examination, contact your physician the next day.
