But exomphalos arising from aneurism, or the presence of flatus, we must abandon as hopeless, like other cases of aneurism. * * * * * COMMENTARY. Celsus gives an interesting abstract of the ancient opinions upon this subject, but as it differs but little from our author’s description, we shall not dwell very particularly upon it. He directs us to cure the disease either by passing through the tumour a needle armed with two threads, in the manner described for staphyloma, or to produce mortification of the part by pressure between two rules. Some, he says, first make an incision in the tumour, so as to be enabled to remove with the greater facility whatever is protruded, but this he thinks unnecessary, as it will be sufficient merely to return the prolapsed substance, and apply a ligature round its base; after which the outer part is to be destroyed by medicines or the cautery. This operation, he adds, will be sufficient, whether the contents of the hernial tumour be intestine, omentum, or water. He intimates, however, that the operation is attended with some danger, and that it is only to be performed between the ages of seven and fourteen, and when the body is in a healthy state. He forbids to interfere with scirrhous tumours. (vii, 14.) The description of the operation given by Albucasis is very minute, but is to the same effect as our author’s. (Chirurg. ii, 52.) Rhases, in like manner, recommends us to pass a needle, armed with two threads, through the tumour, and to secure it by a crucial knot. He, Avicenna, and Haly Abbas evidently copy our author’s description. The operation with the ligature, as first described by Celsus, was revived, with very slight modifications, by the celebrated Desault, of Paris, but is now seldom practised. SECT.
