ABSTRACT
Anorectal malformations are the congenital condition, seen in approximately 1 in 5000 live births. It affects male and female in the ratio of 1.3:1. Anorectal malformations include a wide range of malformations, that not only involves the anus and rectum, but it also involves urinary and genital tract. Aims and objectives of the study, was to understand the structures involved in anorectal malformations by histological study of surgically excised segments of involved part of neonatal intestine and to understand the degree and cause of possible structural impairment in different segments of involved parts of neonatal bowel that may help in the surgical management of anorectal malformations. Present study was conducted on surgically excised segments of fifteen cases of anorectal malformations, that have been collected from Department of Paediatrics Surgery, IMS, BHU. After that processing of the samples have been done and blocks have been prepared. Then after sectioning and staining with Hematoxyline and Eosin, findings have been noted under the microscope. Histopathological examination revealed the abnormalities of varying degrees. To conclude this study supports that the malformed segments should be excised, regarding controversial issue of preserving or excising the distal segment of anorectum for better functional outcome.
