Background
Gastroschisis is a malformation consisting of an abdominal wall defect with eviscerated bowel. Its standard treatment is postnatal repositioning or temporary prosthetic bag placement. The aim of our study is to evaluate the feasibility of its fetoscopic management in a lamb model.
Methods
At mid-gestation (day 75), gastroschisis was created in eight German blackhead sheep. A second fetoscopic procedure was performed on day 105, assessing the viability, extension, and potential for repositioning of eviscerated bowel. The fetus was retrieved by Cesarean section on day 132 and evaluated.
Results
In six fetuses gastroschisis could be successfully created and assessed with fetoscopy. Two fetuses were lost due to technical complications. Primary repair by repositioning the intestine into the abdomen was not possible because it grew into an inflammatory conglomerate too large for the small fetal abdominal cavity.
Conclusions
Although technically demanding, we were able to produce and reassess six cases of gastroschisis by fetoscopy. As primary repositioning appears unfavorable, fetoscopic prosthetic bag placement may become an alternative.
