Abdominal expansion as a bridging technique in stage IV-S neuroblastoma with massive hepatomegaly.

Stage IV-S neuroblastoma has a relatively favorable outcome. However, urgent surgical treatment may be necessary for management of life-threatening complications related to massive hepatomegaly caused by metastatic tumor infiltration. The enlarged liver often becomes of primary concern because diaphragmatic elevation results in life-threatening respiratory embarrassment. An external SILAS-TIC dome has been used as a temporizing procedure to decrease the intraabdominal pressure. The authors developed a modification of this approach using an internal polytetrafluoroethylene patch to create a ventral hernia. This technique decreases the potential complications of prosthetic material use, namely, risk of infection. The graft may be left in place for an extended period and removed in staged operations as the bulk of the metastatic tumor regresses.
