title: Advantages and pitfalls of amnion inversion repair for the treatment of large unruptured omphalocele: results of 22 cases.
abstract: This is a report of our experience with 22 cases of large unruptured omphaloceles treated by amnion inversion during the period 1973 through 1990. The method is characterized by three stages: (1) a silastic sheet is sutured directly to the skin around the amniotic membrane, under local anaesthesia, without dissection between the skin and the amnion; (2) the reduction of herniated viscera into the abdominal cavity is achieved by squeezing the sheeting using a specially modified stapler; and (3) the amniotic membrane is preserved intact, and inverted into the abdominal cavity at the time of abdominal wall closure. Of the 22 infants, 19 survived with satisfactory results. Two patients died of multiple associated anomalies, and the remaining patient died of sepsis arising at the time of the final abdominal closure. This procedure has proved to be effective and safe for high-risk patients with congenital heart diseases, anal atresia, tracheoesophageal fistula, or bronchial stenosis and prematurity. The practical aspects of the procedure, as well as its advantages and pitfalls, are illustrated.
