Persistent processus vaginalis presenting as hydrocele and hernia

S. Prabakaran, K. Kasthuri Thilagam

Abstract


Background: Inguino-scrotal swelling is a common finding in the paediatric population, attributed to the persistent processus vaginalis. But the reason why some children present with hernia and some with hydrocele is not yet clear. Histological examination of the sac may be useful in understanding the reason for this differential presentation. Hence the current study was undertaken to assess the association between type of clinical presentation and histological findings in pediatric population.

Methods: A prospective observational study was done on 51 children aged below 12 years presenting with inguinoscrotal swelling and subsequently diagnosed with either hernia or hydrocele and treated with surgical intervention. The samples were sent for histological examination and analysed for association with diagnosis.

Results: There were 31 Inguinal hernia and 20 Hydrocele subjects. The predominant age group was 6 to 10 years. The number of children with hydrocele right and left, inguinal hernia right and left was 21 (41.2%), 10 (19.6%), 17 (33.3%) and 3(5.9%) respectively. All hydrocele subjects had mesothelial lining, smooth muscle but scanty lymph vessels and absent inflammatory cells. 95% of the Inguinal hernia subjects had low cuboidal lining, inflammatory cells, and lymph vessels.

Conclusions: Paediatric inguinal hernias and hydroceles are due to incomplete or abnormal obliteration of the processus vaginalis. Mesothelial lining, Presence of smooth muscle, Scanty lymph vessels, absence of inflammatory cells are characteristic of Hydrocele Inguinal hernia is characterized by low cuboidal lining, absence of smooth muscles, presence of lymph vessels and inflammatory cells.
