“…Brookes, Waterhouse, and Thorn (1960) found that the majority of post-operative deaths were due to leaking suture lines, respiratory and cardiovascular causes, and that, with the exception of the former, the mortality increased with age. Their findings are in accordance with the experience of others (Armstrong and Penick, 1960;Everson, Hutchings, Eisen, and Witanowski, 1957). A leaking duodenal stump is probably the commonest intraabdominal cause of post-operative death.…”
