Abstract
31 perforations and 28 cases of haemorrhage from proved peptic ulcer which occurred during pregnancy have been reported. The authors add 2 cases of bleeding duodenal ulcer near to term. These were treated in one case by Caesarean section plus partial gastrectomy at the same time and in the other case by partial gastrectomy during the puerperium. The oestrogen level and the greatly elevated histaminase concentration afford part of the explanation why symptoms, and especially complications, from peptic ulcer are so rare during pregnancy.
