Background/PurposeThe purpose of this study is to present a summary of paediatric Spigelian hernia (SH) reported to date, and discuss possible aetiology of SH associated with ipsilateral ectopic testis (SH-ET).MethodsSearch of PubMed, Medline, Embase, and CINAHL was performed using keywords “Spigelian hernia”. The following were extracted from articles describing paediatric SH: demographics, site and contents of SH, comorbidities, proposed aetiology, presence of ipsilateral inguinal canal (IC) and gubernaculum (G).ResultsThere were 78 patients with 88 hernias (69 male, 19 female), including 55 male (19 left, 22 right, 7 bilateral) and 16 female (5 left, 5 right, 3 bilateral) nontraumatic SHs. In nontraumatic male SH, 29 hernias contained testis (10 left, 11 right, 4 bilateral), 15 did not, 10 had no data. Of 29 SH-EH, 15 were lacking IC and G, 3 were missing IC (no G data) and 2 had absent G (no IC data).The combination of SH and cryptorchidism is increasingly recognised as a distinct syndrome. However, there is controversy as to the pathogenic mechanism of this association. We hypothesise SH-ET develops because the G, and therefore IC and line of descent, become cranially ‘mislocated’ along the mammary line, which overlies the Spigelian fascia.ConclusionSH is rare in children. SH-ET may result by testicular descent to an ectopic site along the embryological mammary line.
