“…It is universally agreed that in meconium ileus the obstruction is the direct result of the abnormal physical character of the meconium. Further, in cases uncomplicated by obstructing bands, atresia or volvulus, the morbid anatomical picture is uniformly that of a distended ileum only slightly affecting the terminal loop, and a contracted empty large bowel (Dodd, 1936;Sobel, 1941;Sprenger, 1942;Kaufmann and Chamberlin, 1943;Farber, 1944b;Riniker, 1946). Except for the age of the patient the case recorded here closely parallels the features of meconium ileus.…”
