Hello! Is colonoscopy painful? It's a question many people have. In fact, colonoscopy, rectum usually takes place in about 20-30 minutes, depending on how easy or difficult the colon is and whether there is a surgical intervention such as colon polyp removal or biopsy?
It is possible that colonoscopy causes pain when the scope passes through the flexure and causes abdominal distension. In the case of severe pain such as patients who have undergone abdominal surgery, causing adhesions of the large flexed colon, these cases should perform colonoscopy under anesthesia. This is an endoscopic anesthetic procedure using intravenous anesthetic, the patient will be asleep during the procedure and will not feel any discomfort.
