Complete colorectal tubular duplication is very rare congenital anomaly and its association with anorectal malformation is extremely rare. Preoperative diagnosis is very difficult and management is also challenging. We report a case of a newborn present as a bucket handle variety of anorectal malformation which was per-operatively diagnosed as an ARM with rectal duplication. At his 14th months of age on laparotomy patient was diagnosed as a case of ARM with total colonic duplication with single appendix. We managed the case successfully without extensive bowel resection in staged procedure.
