Abstract：
Chronic intestinal schistosomiasis (CIS) refers to the long-term effects of infection with Schistosoma parasites in the intestines. This condition typically develops after repeated or prolonged exposure to contaminated freshwater containing Schistosoma eggs. The current study reports a case of an adult male, who complained of abnormal abdominal and anal pain for a month and had a medical history of complex perianal fistulae. The endoscopic investigation revealed different degrees of hyperemia, concentrated in the sigmoid colon and rectum. Lesions were localized in the rectum and sigmoid colon. Yellow granular hyperplasia, whether concentrated or dispersed, single or multiple polyps, along with observations of mucosal congestion, edema, faint vascular striations, erosions, superficial ulcers, and scattered petechial hemorrhages were noted. Also, the segmented areas of the colon had different degrees of inflammation. The microscopic histopathological analysis showed a culprit of surgical scar tissue. The granulomas harbored Schistosome parasites at the submucosal depth. Also, an erosion in the colonic mucosal tissues accompanied by lymphoplasmacytic and micro-abscess infiltrates was seen. A Schistosoma bilharzial ova was observed in the granuloma at the submucosal level. Endoscopic and histopathological investigations are useful tools to differentiate between CIS and Crohn\'s disease. These tools can distinguish CIS from Crohn\'s disease. Early detection and treatment are essential to prevent the progression of the disease and minimize long-term complications.
摘要：
慢性肠道血吸虫病（CIS）是指肠道中血吸虫寄生虫感染的长期影响。这种情况通常在反复或长时间暴露于含有血吸虫卵的受污染淡水后发展。目前的研究报告了一个成年男性的案例，主诉腹部和肛门异常疼痛一个月，有复杂肛周瘘病史。内镜检查显示不同程度的充血，集中在乙状结肠和直肠。病变位于直肠和乙状结肠。黄色颗粒状增生,无论是浓缩还是分散，单个或多个息肉,随着粘膜充血的观察，水肿,微弱的血管条纹，侵蚀,浅表溃疡,并注意到散见性出血。此外，结肠的分段区域有不同程度的炎症。显微组织病理学分析显示是手术疤痕组织的罪魁祸首。肉芽肿在粘膜下深度有血吸虫寄生虫。此外，结肠粘膜组织出现糜烂，伴有淋巴浆细胞性和微脓肿浸润。在粘膜下水平的肉芽肿中观察到血吸虫。内镜和组织病理学检查是区分CIS和克罗恩病的有用工具。这些工具可以区分CIS和克罗恩病。早期发现和治疗对于预防疾病进展和最大限度地减少长期并发症至关重要。
