OPERATION FOR THE REMOVAL OF AN ARTIFICIAL ANUS, in cases where the bowel is patent below.--After the operation for hernia in a case where the bowel is gangrenous, the only hope of the patient's recovery consists in the formation of adhesions between the bowel and the external wound, and the presence, for a time at least, of an artificial anus. If adhesions do form, and the patient recovers, it becomes a matter of great importance for his future comfort that the canal of the intestine should be re-established, and the fistulous opening allowed to close. This, however, is by no means easy, as even when the portion of intestine destroyed has been very small, a septum or valve remains which directs the contents of the bowel outwards, and so long as it exists is an effectual obstacle to any of the fæcal contents passing into the distal portion of the bowel. This septum or éperon is formed by the mesenteric side of the two ends of the bowel. To destroy this without causing peritonitis is the aim of the surgeon, and it is not an easy matter to accomplish. To cut it away would at once open the peritoneal cavity, so the mode of treatment now adopted in the rare cases where it is necessary is that recommended by Dupuytren. The principle of it is to destroy the éperon by pressure so gradual as to cause adhesive inflammation between the two surfaces, and thus seal up the cavity of the peritoneum, before the continuance of the same pressure shall have caused sloughing of the septum. This is managed by the gradual approximation by a screw of the blades of a pair of forceps, to which Dupuytren gave the name Enterotome. The process, which extends over days and weeks, must be carefully watched lest the inflammation go too far. Plastic operations are occasionally required to close the opening after the passage is restored. For a good example of such an operation see _Edin. Med. Journal_ for August 1873, in which Mr. John Duncan describes a case. FOOTNOTES:
