Statement of Sato - (420 - 25 Feb. 1947)
First operation of 22, 23 or 24 May. Ishiyama made a curved incision on the left side of the prisoner to the start of the ribs, tied the blood vessel, retracted the incision, cut the ribs, retracted.
Komori said that a lung was removed. Ishiyama said the operation was very satisfactory; that it would serve as a good guide. He jokingly stated the prisoner would go to heaven; that it was the best way out and that there would be more suffering if he had been beheaded.
About a week later, in the second operation, Ishiyama made an incision about seven inches into the stomach. He told Yakamaru and Sato that they would perform a liver or spleen operation and that such was difficult because of blood vessels.
Ishiyama was also in charge of the operation on the second prisoner in which one-half lung was removed. In the third operation, about 5, 6 or 7 June, Ishiyama made an incision in the skull; gave up hope when he could not stop the bleeding.
