Abstract
Richter’s hernia is an uncommon condition of hernia, in which only a portion of the anti-mesenteric bowel wall is entrapped in the hernia orifice. Although it is a well-recognized entity in adults, Richter’s hernia is much less frequently diagnosed in children, especially in the premature neonate. There has been only one report of this special type of hernia in the neonate in the English literature. Its tendencies to early strangulation and frequent lack of obstructive symptoms make it difficult to be diagnosed before operation. The author presents a unique case in which an inguinal hernia with incarceration and ischemic testis has been diagnosed and surgically proven in a premature newborn. Duplex sonography played an important role in the pre-operative diagnosis because there was no significant evidence of intestinal obstruction. The sonographic features and the findings of its complication are described.
