I wanted to thank the professor Inoue-sensei and members of the endoscopic department for the warm welcome and intensive, useful studies. The knowledges gained during my studies will significantly improve the quality of my work. Experience acquired during masterly performed operations will add confidence in operational endoscopy. I wanted to note the high professionalism of the professor and the staff of the endoscopy department. The organization of the endoscopic department also deserves the highest appreciation, the passage of studies on the basis of this department was as informative and comfortable as possible. Once again, I wanted to thank you for the unforgettable educational process. Looking to the future with the hope of visiting again Showa university hospital. Sincerely yours Arthur Belkov.
