In a ten-year (1960 to 1970) clinical experience with gastrectomy, automated transecting and suturing devices were utilized. Results of operation in 216 cases of duodenal ulcer showed a mortality of 0.6% for elective and 3.7% for urgent resections. Six instances of postoperative obstruction did not require reoperation and two of bleeding did. Source of bleeding in the latter was the ulcer, not the suture line. The technique decreased the difficulties of subtotal gastrectomy, increased the pace of the operation, and lowered the mortality and morbidity.
