An enormous amount of research has yielded considerable information about intestinal obstruction and has resulted in the modification of previous concepts. Admitting that progress has been made, it is evident from a perusal of recent figures on mortality that much remains to be learned. Christopher,1 Miller2 and others have recently reported mortality rates varying between 40 and 60 per cent. When a disease carries such a mortality, no apology need be made for presenting further experimental studies. The fact that over 5,000 articles dealing with intestinal obstruction are on file in the library of the Surgeon General is an indication of the interest of physicians in this disease and an admission that their knowledge of the subject is far from complete.
It is evident that when complete knowledge of the physiologic changes that occur in intestinal obstruction is acquired, physicians will be better equipped to cope with the
