A newborn with caudal duplication and duplex imperforate anus

      Abstract

      There are case reports of duplication of the colon, rectum, anus, urinary system, lower genital tract, and external genitalia, spinal anomalies, and abdominal wall defects. However, it is rare to encounter a single newborn with all of the mentioned abnormalities, which have been defined as the caudal duplication syndrome (CDS). Herein, we present a newborn with an omphalocele, duplex external genitalia (with duplex labia minora and labia majora), duplex urethral orifices, duplex vaginal orifices, and duplex anal dimple with imperforate anus and rectovestibular fistula on both sides. Exploration revealed duplex appendix, colon duplication, duplex uterus (continuing with tuba and ovaries on both sides), duplex rectum, malrotation of the intestines, with the cecum located in the middle of the abdomen, defect in the intestinal mesentery, and internal herniation of the small intestines through this defect. The intestines were operatively reduced and the defect repaired.
