In 14 newborns with gastroschisis, fascial closure was effected by muscular suture associated with teflon mesh prosthesis interposition. This was realized either in urgency during neonatal period (9), either secondly (5). Neonatal cases were treated between 0 h 30 and 5 h of age. Pulmonary hyper-pressure risk was very important when primary suture was early employed (card freq: 150 b. min-1. PA syst: 60 cm Hg; pulm pres: 20 cm Hg). When we used a teflon mesh prosthesis, we had 8 good results and only one initial death. 5 complications were represented by cutaneous ischemia which spontaneously disappeared (1), ischemia with infection and partial necrosis (2), important necrosis with teflon mesh prosthesis exteriorization (2). It has been definitely possible to achieve complete fascial in 7 newborns. Only one of them had a little ventral hernia. 5 newborns were early treated by simple skin coverage (Gross) as primary management. They have had teflon mesh prosthesis between 5 and 14 M of age and have undergone excision of the teflon mesh prosthesis and fascial repair without difficulty (5 good results). With teflon mesh prosthesis for treating congenital abdominal defects, abdominal hyper-pressure and pulmonary complications are exceptional. Local complications are very limited because of good vascular conditions. We did not have any adherences because of teflon mesh prosthesis good biological and histological tolerance. Digestive complications (statis, septicemia...) have been few and mild because physiological intra abdominal pressure has been early obtained.
