Fourthly, if the mother's condition is hopeless, a caesarean section gives the child a chance for life, but the operation will hasten the mother's death in nearly every case. The first and second cases here are not practical. If the surgeon can remove the uterus at term after a caesarean section, that is the most reasonable operation for the mother and child, and it offers no moral difficulty. If the mother's condition is so bad that the uterus may not be removed, the chances are that her death will be hastened by caesarean section, but if caesarean section is not done, from 50 to 63 per centum is the ratio against the saving of the child. I do not think a general rule can be given as regards the certainty of hastening the maternal death: the reckoning is to be made to meet the particular condition. It seems, however, probable that in every case of inoperable carcinoma of the uterus complicating pregnancy a caesarean section would hasten the maternal death. She will die anyhow from the cancer, but in certain cases she may live longer if the section is not done. If, again, a carcinoma of the uterus is inoperable at term, the delivery of the child may be impossible without caesarean section, from uterine inertia, or the opposition of the dense inflamed tissues, or the friability of these tissues. In such a case without the section she would die, and die probably sooner than with it. The operation would possibly slightly prolong her life, by, say, a few hours or days, and it certainly would give the child a very good chance for its life. She may, of course, die upon the operating table, but she would die in childbed without the section. The case is different from the ordinary caesarean section done because of a narrow pelvic bony girdle. In the latter condition the chances that the mother will live are very high if the surgeon is competent, but in the carcinoma case she will die no matter who the surgeon may be, and very probably, or almost certainly, her death will be hastened by the operation in the majority of cases. If the condition is such that the woman can not be delivered {46} without the section, I see no difficulty against operation, because the surgeon can not, as far as I know, say positively whether he will hasten the maternal death or not, and in the circumstances he may take advantage of the doubt. If the woman with an inoperable carcinoma uteri may be delivered _without_ section, should such a delivery be chosen although it raises the chances of mortality as regards the child from about 12 per centum to at the least 50 per centum? It is a matter of a very probable hastening of the mother's death as weighed against the safety of the child--the child has about one chance in two of life without the section, and, say, seven chances in eight with the section. The operation is far preferable as regards the child alone, but not preferable as regards the mother alone. Is it then allowable?
