Evaluation of the location of the anus by a modified technique in the neonate.
OBJECTIVE
The aim of the current study was to bring to notice the anterior displacement of the anus and to recommend the measurement of anal position index in the neonate by a modified method.


METHODS
Sixty newborns (34 girls and 26 boys) were taken into study, and the anal position index (API), which is the ratio of anus-fourchette (scrotum) distance to coccyx fourchette (scrotum) distance, was measured. To obtain the measurement, a transparent adhesive tape was placed along the midline on the long axis, covering the anus. The upper and lower tips and the center of the anal circle was marked and measured using a caliber.


RESULTS
API was found as 0.46 (SD +/- 0.08) and 0.53 (SD +/- 0.05) in female and male neonates, respectively. Because an index of 0.34 in girls and 0.46 in boys are considered abnormal, the 3 female babies in the study group with API indices of 0.18, 0.28, and 0.33 were subjected to further examination. The abnormality was seen not to be rare in the Aegean region.


CONCLUSIONS
An abnormal index alone cannot be the sole cause of constipation mentioned in the literature and therefore not an indication for operation. Anal position index in the neonates could be measured more accurately by the current modified method. If an anterior location of the anus is found early in infancy the baby should undergo follow-up accordingly.
