                            A thin, lighted tube used to view the inside of the stomach. This process is called a gastroscopy. A gastroscope can also be used to take samples of tissue for biopsy and to remove small growths.
                                                            
                                                     
                        
                                                
                        
                        
                            A thin, tube-like instrument used to examine the inside of the stomach. A gastroscope has a light and a lens for viewing and may have a tool to remove tissue.
