Anal tonometry was performed during the first days of life in twelve premature and fourteen mature children without signs of gastrointestinal disease. A new tonometer with small dimensions was used. A pressure decrease of the internal anal sphincter after distension of the rectum could be demonstrated in all children examined and as early as two hours after birth. This was to be expected as the relaxation of the internal sphincter is part of the normal defecation reflex. Thus anal tonometry can be used in the early diagnosis of Hirschsprung's disease presumable already from the very first days of life.
在12名早产儿和14名足月儿出生后的头几天进行了肛门测压，这些儿童均无胃肠道疾病迹象。使用了一种尺寸较小的新型眼压计。在所有接受检查的儿童中，最早在出生后两小时即可观察到直肠扩张后内括约肌压力下降。这是可以预料的，因为内括约肌的松弛是正常排便反射的一部分。因此，肛门测压可用于先天性巨结肠的早期诊断，可能从出生后的第一天就可以使用。
