The aim of this study was to investigate endoscopically and histologically rectal mucosa complications in bilharzia patients. Coprology using KATO's technique was carried out in 1406 school children aged 4 to 18 years. 134 (9.53%) were infested. Among the infested school children and the sample population, a random selection of 80 school children (40 infested and 40 of sample population) was made, in whom rectoscopy and biopsy of rectal mucosa were carried out. The lesions found were classified on endoscopic and histologic basis. The prevalence of the disease 9.53% appears to be in constant regression. Inflammatory lesions are more common in bilharzia patients. Histology facilitated the unveiling of a specific rectitis in 72.5% bilharzia patients and 12.5% of the sample population. This study confirm the effectiveness of the several bilharzia eradication campaigns carried out in the Nkolbisson area. Rectoscopy with biopsy of the rectal mucosa should be reserved to symptomatic patients, in whom many coprologies have turned out negative.
本研究旨在通过内镜检查和组织学检查来调查血吸虫病患者的直肠黏膜并发症。采用加藤技术对1406名4至18岁的学童进行了粪便检查。其中134名（9.53%）受到感染。在受感染的学童和样本群体中，随机挑选了80名学童（40名受感染学童和40名样本群体学童），对其进行了直肠镜检查和直肠黏膜活检。所发现的病变在内镜和组织学基础上进行了分类。该病9.53%的患病率似乎在持续下降。炎症性病变在血吸虫病患者中更为常见。组织学检查发现，72.5%的血吸虫病患者和12.5%的样本群体存在特异性直肠炎。本研究证实了在恩科利比松地区开展的几次血吸虫病根除运动的有效性。直肠黏膜活检的直肠镜检查应仅用于那些多次粪便检查结果均为阴性的有症状患者。
