It will be well to remember that diseases of the cecum or appendix or both never cause complete obstruction, except in exceedingly rare cases where adhesive bands are formed, completing the cut-off. In this connection it will be well to also remember that in absolute obstruction the symptoms of nausea and vomiting, or retching, will continue, while those of appendicitis will stop in three days. In addition to the continued nausea of complete obstruction, the pulse grows weaker and more frequent and the patient shows great anxiety of expression, there is a sickness that can not be accounted for with a diagnosis of appendicitis or typhlitis, and the patient has the appearance of being desperately sick. The great pain at the beginning subsides, the temperature falls, the pulse grows rapid and weak, the skin becomes leaky, the mind becomes dull, drowsy and comatose, then a little wandering and death relieves the suffering in a short time. These symptoms are of collapse and they may come on in the course of a typhoid fever, or other diseases of the alimentary canal; they always mean a fatal toxemia either from obstruction or perforation, and occasionally the only forerunning symptom is sudden abdominal pain. Circumstances must guide in making a diagnosis. If, during a run of typhoid fever, there should be sudden abdominal pain followed with symptoms of collapse and nothing to account for it, it means perforation; an immediate operation may save the patient; nothing else will. A sudden pain in the abdomen of a woman during menstrual life, with positively no unusual menstrual symptoms and no trouble in the right ileo-cecal region, indicates perforation of the stomach or of the gall-bladder. If there have been a menstrual period or two gone over with a slight showing, and some uneasiness, perhaps nausea, perhaps a flow with pain somewhat simulating abortion, a sharp, severe abdominal pain followed with quickening of the pulse and an exceedingly anxious facial expression, ectopic pregnancy with rupture of the tube may be suspected. One must also keep in mind renal calculus in determining bowel diseases. Authors pretty generally unite in declaring that appendicitis is a dangerous disease. In his late book, "The Abdominal and Pelvic Brain," Dr. Byron Robinson of Chicago says, "Appendicitis is the most dangerous and treacherous of abdominal diseases--dangerous because it kills and treacherous because its capricious course can not be prognosed. . . . For years I have made it a rule to recommend appendectomy to patients having experienced two attacks. Fifty per cent of subjects who have had one attack experience no recurrence." In Keating's Cyclopedia of the Diseases of Children, Dr. John B. Deaver of Philadelphia makes the following statements:
