Colonoscopy is a medical procedure that can be performed for both diagnostic and therapeutic purposes. This procedure allows for a detailed examination of the large intestine (colon) and rectum. Colonoscopies are generally performed by gastroenterologists or general surgeons. It is of great importance that the procedure is carried out by experienced physicians to minimize the risk of potential complications. Furthermore, it is recommended to choose fully equipped healthcare facilities with emergency intervention capabilities to address rare but serious risks such as colon perforation.
