Schistosomal appendicitis: A serious and often misdiagnosed condition.

Abstract

Schistosomal appendicitis (SA) is a rare but serious complication of schistosomiasis, a parasitic disease affecting over 250 million people worldwide. A recent retrospective study by Wang et al provides important insights into the clinicopathological characteristics of SA. The study compared 136 cases of SA to 5418 cases of non-SA over a ten-year period. Key findings include a higher average age of SA patients (61.73 years vs 35.8 years for non-SA), a higher proportion of acute on chronic appendicitis (33.1% vs 16%), and a significantly higher incidence of colorectal cancer (11.7% vs 2.2%). Despite these differences, SA remains a diagnostic challenge due to its nonspecific clinical presentation and lack of specific laboratory findings. The study also highlights the persistent prevalence of SA, accounting for 1.6%-3.4% of all appendicitis cases each year from 2013 to 2023. These findings underscore the need for enhanced awareness, early detection, and prompt treatment of SA in endemic regions. Given the association with colorectal cancer, patients with SA require thorough screening and follow-up. Further research into the pathogenesis and diagnostic markers of SA is warranted. As the global battle against schistosomiasis continues, targeted efforts to diagnose and manage SA can significantly improve patient outcomes.
