Closing left gastroschisis with vanishing left testis.

We report a baby boy with gastroschisis with left non-palpable undescended testis who had a defect on the left side of an intact and normal umbilical cord and had associated testicular atrophy and abnormalities of the ductus deferens. They were successfully managed by primary repair and had uneventful recovery. Subsequent inguinal exploration confirmed blind ending vas deferens and vanishing left undescended testis. Our case confirms vascular accidents at the narrow abdominal wall defect can lead to vanishing testis following attempts at closing gastroschisis making the defect narrow and compromising the blood supply to the testis.
