摘要:

患者,男,46岁,于2021年12月在体检中行肠镜检查时,发现其回盲部寄生一条似寄生虫,可蠕动,予活检钳取出。肠镜下,虫体寄生部位的肠黏膜未见异常,肠腔内未见异常。取出的虫体经形态学鉴定,初步确定为简单异尖线虫;提取虫体DNA,进行PCR检测,所得扩增片段约为1 000 bp,测序后经BLAST比对分析,与简单异尖线虫的序列一致性达99%;经系统进化树分析,与简单异尖线虫聚为一簇。确认该患者回盲部寄生的虫体为简单异尖线虫。患者自述,长期居住于东南沿海城市,有多年食生海鲜制品史。取出虫体后未诉有不适感,故未行其他检查和治疗。

Abstract:

An 42-year-old male patient who was found to have a parasite in his ileocecal region during a colonoscopy examination in December 2021. The worm was reported motile and was removed with biopsy forceps. During the colonoscopy, no abnormality was found in the intestinal mucosa where the parasite was found and no abnormality was found in the intestinal lumen. The extracted parasite was identified as Anisakis simplex preliminarily by morphological identification. DNA was extracted from parasites and tested by PCR. The amplified fragment was about 1 000 bp. After sequencing, BLAST analysis showed that it was consistent with Anisakis simplex up to 99%. By phylogenetic tree analysis, it was clustered with Anisakis simplex. The parasite was confirmed to be Anisakis simplex. The patient reported that he had lived in southeast coastal cities for a long time and had a history of eating raw seafood products for many years. No discomfort was reported after the parsite was removed, so no other examination and treatments were performed.
