Abstract

Background: Invertogram has been used to evaluate the level of blind rectal pouch in neonates with anorectal
malformations (ARM) for over 80 years. In recent years, prone lateral cross-table radiograph (PLCTR) has been
recommended for demonstrating these anomalies, providing equivalent information as the traditional procedure.
Objective: The aim of this study was to compare the effectiveness in evaluation of rectal pouch level in ARM
between invertogram and PLCTR.
Materials and Methods: During January 2009 to June 2012, all of the neonates with ARM who had no evidence
of cutaneous, urinary or genital fistula underwent both invertogram and PLCTR for demonstration of the blind rectal
pouches. Demographic data and radiographic findings of the patients were collected and analyzed.
Results: Fifty -two neonates with ARM (46 males and 6 females) were available for the study. Thirty-nine
patients (75%) were full term babies, whereas 13 patients (25%) were premature. Invertogram and PLCTR were done
within 13 to 36 hours after birth. Radiographic findings of the two methods in 46 patients (89%) were not different.
In the remaining 6 cases (11%), the findings of PLCTR were more accurate, with confirmation by colostomy study
(loopogram) or operative findings, while the evidence of rectal gas shadow in the invertogram revealed higher than
the actual levels.
Conclusion: PLCTR is much easier to position, less time consuming and more accurate in some cases than
invertogram regarding interpretation of the level of rectal pouch in ARM. PLCTR should be routinely used instead
of invertogram for evaluation in ARM.
