A case of delayed separation of the umbilical cord is reported. Ultras
onography and radiographic examination of the stump showed connection
with the bowel. During surgery the cord was found to contain the appen
dix. The authors hypothesize that this anomaly represents a small omph
alocele, resulting from failure of the gut to withdraw completely from
the umbilical cord, or, less likely, a hernia. (C) 1995 by W.B. Saund
