A Meckel's diverticulum or remnant of the vitelline duct is said to be present in about 2% of all postmortem examinations.* Although many persons live their normal span of life asymptomatically despite this anomaly, we have been impressed that its presence may be made known dramatically by its initiating serious surgical complications in the pediatric age group. In this report we have reviewed the records of 60 patients in the pediatric age group who demonstrated surgical complications of this lesion. None of the patients whose Meckel's diverticulum was discovered as an incidental finding at laparotomy for other lesions † are included in this paper. Age Incidence The ages covered range from 1 day to 14 years, and it is noted that 27, or 45%, of the patients were in the newborn or infant group, and 45, or 75%, of the patients were 5 years or younger (Fig. 1).
