Pre- and postnatal botulinum toxin abdominal wall muscle relaxation in hepato-omphalocele.

Introduction: Giant omphalocele poses a conflict between eviscerated content and abdominal capacity, with associated risks such as compartment syndrome or cardiovascular compromise.

Clinical Case: We present the case of a prenatally diagnosed hepato-omphalocele, without associated abnormalities. At week 37, botulinum toxin was injected in the right hemiabdomen under fetal and maternal sedation.
