Exstrophy-Epispadias Complex With Isolated Ectopic Bowel Segment: A Case Series and Literature Review.

OBJECTIVE

To present a case series of the exstrophy-epispadias complex (EEC) with isolated ectopic bowel segment (IEBS) with the literature review, highlighting the clinical findings and treatments.

MATERIALS AND METHODS

We present 3 cases of bladder exstrophy (BE) with IEBS in our institute and reviewed the literature in PubMed with the terms "("bladder exstrophy" OR "epispadias") AND ("visceral sequestration" OR "sequestered" OR "ectopic bowel")."

RESULTS

There were 2 males and 1 female. The IEBS was detected by physical examination in 2 cases and by ultrasonography in another one. All cases were BE accompanying with lower abdominal mass which adhered to the bladder wall but was separated from the digestive system. All cases underwent the IEBS excision and BE repair simultaneously. Pathological result of IEBS suggested the histological structures of colon. There were totally 13 cases of EEC with IEBS reported in the literature, including 2 (15%) epispadias, 9 (69%) covered BE, 1 (8%) duplicate BE and 1 (8%) classic bladder exstrophy. Although their clinical manifestations were various, IEBS excision were safely conducted in all cases.

CONCLUSION

EEC with IEBS is an extremely rare congenital malformation. Physical and imaging examinations are important for diagnoses. Surgical excision is safe and effective for managing IEBS.
