Intestinal obstruction is a poorly recognized and probably underreported complication of strongyloidiasis. We present herein an unusual case, of complete duodenal obstruction caused by S. stercoralis.
A systematic review of the literature examining the clinical course, diagnostic methods, and outcome of this rare complication of strongyloidiasis was performed.
A 42-year-old woman presented with a 5-month history of abdominal pain, vomit, and weight loss. An abdominal CT scan showed an obstruction of the third part of the duodenum. Segmental intestinal resection was carried out and histopathology examination revealed heavy Strongyloides stercoralis infestation. Duodenal obstruction is a rare complication of S. stercoralis infection, with only 8 cases described in the literature since 1970. Most of the patients are males, middle-aged, and the diagnosis was made by duodenal aspirate/biopsy, or analysis of surgical specimen.
Duodenal obstruction is an unusual, but potential fatal, complication of S. stercoralis infection. The large spectrum of clinical manifestation and lack of classic clinical syndrome make the final diagnosis of strongyloidiasis extremely difficult. A high index of suspicion, mainly in patients from endemic areas, is needed for correct and early diagnosis of this uncommon presentation of Strogyloides stercoralis enteritis.
肠阻塞是一种未被充分认识且可能报道不足的寄生虫感染并发症。本文报告了一例由 Strongyloides stercoralis 引起的完全性十二指肠阻塞的罕见病例。
对检查该寄生虫感染罕见并发症的临床病程、诊断方法和结局的文献进行了系统回顾。
一名 42 岁女性因腹痛、呕吐和体重减轻 5 个月就诊。腹部 CT 扫描显示第三段十二指肠阻塞。进行了节段性肠切除术，组织病理学检查显示存在大量 Strongyloides stercoralis 感染。自 1970 年以来，文献中仅描述了 8 例由 S. stercoralis 感染引起的十二指肠阻塞，这是一种罕见的并发症。大多数患者为男性，中年，通过十二指肠抽吸/活检或手术标本分析做出诊断。
十二指肠阻塞是 S. stercoralis 感染的一种不常见但潜在致命的并发症。临床表现范围广泛且缺乏典型的临床综合征，使得强虫感染的最终诊断极具难度。对于这种不常见的 Strongyloides stercoralis 肠炎表现，主要在来自流行地区的患者中，需要高度怀疑，以实现正确和早期诊断。
