A Case Report of a Colorectal and Caudal Duplication Syndrome Associated with Caudal Regression Syndrome

We describe an uncommon clinical presentation of caudal duplication syndrome and features of caudal regression syndrome in a female infant with complex urogenital and colorectal duplication associated with lipomyleomeningocele and left lower limb hypoplasia. A staged surgical treatment plan was carried out to maintain fecal and urine continence, potential fertility, and cosmetic appearance.

A Rare Sonographic Case of Caudal Duplication Versus Polymelia

Caudal duplication is a rare condition that results in varying degrees of duplication of organs within the gastrointestinal, genitourinary, reproductive, spinal, and vertebral systems. Polymelia is a rare congenital defect that presents as supernumerary limbs. This case report describes a fetus with characteristics of both conditions but does not present with the classic scenario of either condition.

Caudal Duplication Syndrome Systematic Review—A Need for Better Multidisciplinary Surgical Approach and Follow-Up

Background and Objectives: Caudal duplication syndrome is a rare association of anatomical anomalies describing duplication of the hindgut, spine, and uro-genital structures, leading to varied clinical presentations. The current literature focuses on case reports which describe the embryological etiology and anatomical spectrum of the condition giving little attention to the surgical preparation, the need for a well-structured follow-up program, or the transition into adult healthcare of these complex patients. No reviews have been published regarding this complex pathology. Materials and Methods: A review of caudal duplication syndrome cases was done to assess the range of the clinical malformations, timing, and types of surgical interventions. Inconsistencies in multidisciplinary care, follow-up, and risk events were described. Results: Hindgut duplication always involved the anorectal region. Anorectal malformations were evenly distributed as unilateral and bilateral. Colon duplication extended from the anal region to the transverse colon or ascending colon in most of the cases and less to terminal. In females, genital duplication was present in all cases. The follow-up period varied between 3 months and 12 years. In all adult females, the motive of presentation was related to pregnancy (complications after successful delivery, fertility evaluation) or late complications (fecalith obstruction of the end-to-side colon anastomosis, repeated UTIs with renal scarring). Conclusions: Complex malformations affecting multiple caudal organs may have a strong impact in many aspects of the long-term quality of life; therefore, patients with caudal duplication syndrome need increased awareness and joined multidisciplinary treatment.

Caudal duplication syndrome in an adolescent: Rare concoction of duplication anomalies

Caudal duplication syndrome is a rare and interesting entity with a reported prevalence of <1/100,000 births. Caudal duplication syndrome encompasses a diverse spectrum of anomalies primarily involving partial or complete duplication of organs comprising the gastrointestinal, genitourinary and distal neural tube systems. The term ‘caudal duplication syndrome’ was coined by Dominguez et al. in 1993, in a case series of six patients presenting with findings pertaining to duplication anomalies of genitourinary system, hindgut, lumbosacral spine and cord. We here report a unique case of caudal duplication presenting in late adolescence and briefly review the available literature on this rare abnormality.
