: Schistosoma haematobium infection is acquired early in life with the peak prevalence and intensity of infection occurring in the second decade of life in endemic areas. The aim of this study was to establish any association between S. haematobium infection and development of inguinal hernia in school age children in a S. haematobium highly endemic area in Zambia. Methodology : An analytical study was conducted at St Paul’s Mission Hospital, Nchelenge, Luapula province, Zambia. Hospital operating theatre records were reviewed for inguinal hernia repair operations in school age children. Results : There were 45 inguinal hernia repair operations conducted in male school age children presumed to be infected with S. haematobium between July 2010 and July 2015. The mean age of these children was 9.6 years while the age range was from 6 years to 14 years. The overall prevalence of S. haematobium in school age children in the area ranged from 89.5% to 95.5% during this period. Conclusion : Inguinal hernia is a probable complication of S. haematobium infection in school age male children.

Over 112 million people in sub-Saharan Africa alone are infected by S. haematobium annually. The infection is acquired quite early in life with both the prevalence and intensity of infection peaking in the second decade of life. Hence school age children are prone to this infection in endemic areas. The infection is asymptomatic in most cases. Symptomatic cases may present with haematuria which is terminal, abdominal pains, dysuria affecting about 30 million people in endemic areas, and straining on urination. Complications of schistosomiasis haematobium reported in literature include cystitis and ureteritis which may progress to squamous cell carcinoma of the urinary bladder, hydronephrosis and hydroureters affecting 10 million people in endemic area of the world, renal failure leading to 150,000 deaths annually, and Central Nervous lesions such as transverse myelitis with flaccid paraplegia. No other complications of schistosomiasis haematobium requiring surgical intervention have been reported in literature. During a study in which we screened school children aged between 5 and 14 years for S. haematobium at Kenani and Chandwe Primary schools in Nchelenge, Luapula province of Zambia in 2005 we found the prevalence of S. haematobium to be 95.5% and 89.4 %, respectively. This literally meant that all the school age children in this region were infected with S.haematobium. We observed that some of the school children in the study had difficulties in submitting the required volume of urine for the urine filtration and examination for S. haematobium ova procedure. The volume submitted by these children was too little. We made an assumption that due to the infection, the affected children were straining themselves to urinate and give the required volume of urine. Straining on urination has the risk of raising the abdominal pressure with a probability of the affected individual developing inguinal hernia. In this article we present findings from a review of the operating theatre records on inguinal hernia repairs conducted on school age children admitted to St. Paul’s Mission Hospital in Nchelenge district of Zambia between July 2010 and July 2015. The aim of this study was to establish any association between S. haematobium infection and occurrence of inguinal hernia in school age children in an area highly endemic for S. haematobium.
