Since the first definition of anal canal little has been discovered about the etiology of this rare condition. We present four asymptomatic cases of anal canal duplication with diverse clinical and surgical findings.
A retrospective chart review was performed on four infants presenting with asymptomatic anal canal duplication, born between 2014 and 2016. Clinical characteristics and pathologic findings of patients either by radiological imaging or pathology were evaluated. The primary outcome measure was the complications.
All patients were followed-up with physical examination and ultrasound for a mean of 3.5±1.0 years, lastly seen at the beginning of 2018. The female to male ratio was 3:1. Duplicate anal canal length varied between 12-20mm, and two of the four patients had a presacral cystic mass confirmed as a tail gut cyst following surgery. At follow-up, none of the patients had developed symptoms related to anal canal duplication, regardless of whether they had surgical intervention.
Though surgical management is the preferred treatment for anal canal duplication, it seems that patients who do not undergo surgery might remain free of symptoms, suggesting that surgical intervention may be unnecessary.
自肛管首次被定义以来，关于这种罕见病症的病因鲜少被发现。我们呈现四例无症状肛管重复畸形病例，伴有多样的临床和手术表现。
对2014年至2016年间出生的四例无症状肛管重复畸形婴儿进行回顾性病历审查。通过影像学检查或病理学评估患者的临床特征和病理结果。主要观察指标为并发症。
所有患者均接受体格检查和超声随访，平均随访时间为3.5±1.0年，最后一次就诊时间为2018年初。男女比例为3:1。重复肛管长度在12 - 20毫米之间，四名患者中有两名在手术后经证实骶前囊性肿块为尾肠囊肿。随访时，无论是否接受手术干预，所有患者均未出现与肛管重复畸形相关的症状。
尽管手术治疗是肛管重复畸形的首选治疗方法，但未接受手术的患者似乎也可能无症状，这表明手术干预可能不必要。
