The standard biopsy method in the stomach, small intestine and large intestine is endoscopic biopsy. In this biopsy performed by gastroenterology or general surgery specialists, the stomach, duodenum or inner part of the large intestine (lumen) is seen by entering through the mouth or anus, and many samples are taken from suspicious areas. This biopsy method is ideal for masses that grow inwards, ie towards the lumen. However, gastrointestinal masses sometimes grow outwards rather than inwards. Since these masses cannot be seen with the endoscope, a piece cannot be taken in the classical way. In such masses, percutaneous needle biopsy can be easily performed under the guidance of tomography and pathological diagnosis can be made.
With percutaneous (through the skin) cutting needle biopsy, biopsy can be taken from masses originating from both the stomach, small intestine and large intestine wall and growing outward. Many studies in the literature have shown that this method is safe and has high accuracy. In our center, percutaneous biopsy has been performed for such masses for years and no serious complications have been observed so far.
