The use of intra-abdominal tissue expansion for the management of giant omphaloceles: Review of literature and a case report

Giant omphaloceles present a reconstructive challenge in planning, management, and eventual closure of the abdominal wall defect. The goal of reconstruction is to recreate a functional abdominal wall domain and return the extra-anatomically placed viscera into the peritoneal cavity in a safe manner. Traditionally, placement of tissue expanders has been in the subcutaneous and intramuscular planes. Recently, however, there have been reports of intra-abdominal placement of expanders. We present a detailed review of the literature regarding the use of tissue expanders in the management of giant omphaloceles with specific emphasis on the intra-abdominal technique of placement. We also present a case report with the longest follow-up till date in which the patient underwent staged reduction using the intra-abdominal approach. Initial reports of this modality are promising both as a primary strategy and in patients in whom conventional techniques have failed. Results from our review of literature and case report suggest that this technique appears to be durable and effective with successful functional and cosmetic outcomes.
