Appendicitis schistosomiasis: unusual lesion about two cases in Senegal

Abstract

Appendiceal schistosomiasis is a rare disease of only histopathological diagnosis. Appendectomy should be followed by treatment with praziquantel to avoid complications. We report two cases of appendiceal schistosomiasis while discussing the place of this infection in the pathogenesis of appendicitis. Finally we recommend a routine pathological examination of any part of appendectomy for better care for patients.

Bilharzia Appendicitis: Incidence in a Commune in Mali, about 3CAS

“…So after only 12 months of activity we identified 3 cases appendicitis bilharzia 51 histological studies performed or 5.9% of cases, our rate of completion of the pathological examination was 57.30%. In Senegal, in the Thiam study, after analysis of 3208 appendectomy over 10 years, he found 2 cases [14], in Mozambique on a series of 145 cases of appendicitis in Beira 13.1% or 9 cases were bilharzia appendicitis [7]. Similar work was carried out in Hong Kong, Ghana and Nigeria with frequencies of 0.2%, 2.4% and 2.9% respectively [14].…”

“…The etiologies of appendicitis are diverse and varied [14]. Schistosomiasis infection should be considered as a possible cause of appendicitis not only in endemic areas but also in developed countries [7].…”

“…In our study, this examination allowed us to confirm the bilharzia infestation of the appendix. The presence of Schistosome eggs requires specific antiparasitic treatment after appendectomy, with praziquantel at the single dose of 60 mg/Kg; since appendicular bilharzia is often associated with other visceral locations (bladder, intestinal, hepatosplenic…) [14]. In the absence of treatment, occlusive or neoplastic mechanical complications may occur.…”

“…In the absence of treatment, occlusive or neoplastic mechanical complications may occur. Only a histopathological examination can confirm the bilharzia involvement of the appendix, hence the interest of a systematic anatomo-pathological examination in front of any appendectomy piece [14].…”
