An anesthesia gastroenteroscopy costs about $2,000, depending on the hospital where it is performed and whether other tests are performed. Anesthesia gastroenteroscopy, also known as painless gastroenteroscopy, is divided into two parts, gastroscopy as well as enteroscopy, and because it is painless, the most important part of it is the anesthesia. A painless gastroscopy costs about $700 and a painless colonoscopy costs about $1,000, depending on the hospital, and there may be diarrhea-inducing medications used during the colonoscopy. In addition, if a lesion is found during the gastroenteroscopy, tissue extraction and biopsy of the lesion will be required, which will also affect the final cost. It is important to consult a professional doctor before having a painless gastroenteroscopy, who will explain the precautions to be taken and the costs involved.
