The passage of meconium alone is not a sign of correctly positioned anus.J Matern Fetal Neonatal Med. 2015 Feb; 28(3):303-5.JM
The aim of this study is to determine the consequences of delayed presentation of anorectal malformations and emphasize the causes of delayed diagnosis of these malformations.
We retrospectively reviewed 54 neonatal patients with a diagnosis of anorectal malformations. Group 1 consisted of 35 patients diagnosed within the first 48 h of life and Group 2 included 19 patients diagnosed after 48 h of life.
Obstructive symptoms at the time of diagnosis, overall complications and the mean postoperative hospitalization period in Group 2 were markedly higher than that of Group 1. A comprehensive neonatal examination within the first 48 h of life was performed in 32 (91.4%) patients in Group 1 and 5 (26.3%) of the patients in Group 2 (p < 0.001).
The passage of meconium is not the only sign of correctly positioned anus. A careful physical examination and awareness of this anomaly are of great importance in making a timely diagnosis of anorectal malformations.
