[Review on the process of my studies in surgery of the stomach].

Achievements worth referring were selected from among the literature on gastric studies that were conducted since 1947 in my surgical department of Jikei University. And talks upon process of the studies were reminiscently given in terms of the following subjects. Why I was attracted by ulcer surgery, Experimental studies on gastroenterostomy and ulcer, Topography and extent of gastrectomy, advocation of the dual control mechanism theory, and My association with vagotomy.
