11. The subject of _Spontaneous Perforation of the Stomach_ is an important topic for the medical jurist, because both the symptoms before death and the appearances in the dead body are occasionally very like the effects of some of the most active irritant poisons. The following is a statement of the most material facts hitherto ascertained on this subject; but it must be premised that a good deal of obscurity still hangs over some parts of it. Spontaneous perforation of the stomach is of three kinds. One is the last stage of some varieties of scirrhus. The indurated membrane ulcerates, the ulcer penetrates first the villous, then the muscular, and at last the outer or peritoneal coat, so that the contents of the stomach escape into the belly. The symptoms of the perforation are a sense of something giving way in the pit of the stomach, acute pain gradually extending over the whole abdomen, great tenderness and tension, excessive prostration, and death commonly within twenty-four hours. The symptoms which precede the perforation in general clearly indicate organic derangement of the stomach, namely, aggravated dyspepsia of long standing. Several cases of this description may be seen in a thesis by M. Laisné,[175] a pupil of Professor Chaussier. Two characteristic cases have been published by Dr. Crampton;[176] and Mr. Alfred Taylor has referred to several others, the stomachs of which are preserved in Guy’s Hospital Museum, and gives the particulars of some which had occurred in the practice of that institution or to his friends.[177] Occasionally no symptom exists prior to the perforation, as in an instance related by Dr. Kelly of a stout healthy servant, who was suddenly seized with excruciating pain in the stomach and expired in eighteen hours, and in whose body the stomach was found perforated in the middle of an extensive thickening and induration of the villous coat.[178]
