BACKGROUND
Duplication cyst of the duodenum is rare. This study describes a case of duodenal duplication and evaluates its clinical features through a literature review.
METHODS
A case of duodenal duplication is reported, and related articles published from 1999 to 2009 on PubMed were reviewed. Clinical manifestations, diagnostic examinations, and methods of management were analyzed.
RESULTS
Including this report, there had been 38 citations in literature that provide adequate descriptions of 47 cases of duodenal duplication cysts. Nineteen (40.4%) were discovered before 10 years of age, whereas 10 (21.3%) were found in the second decade. The remaining 18 patients (38.3%) were older than 20 years. The case number decreased as age increased. Overall, 80% of cases presented with abdominal pain, and 53% were complicated with pancreatitis.
CONCLUSIONS
The most common symptom in duodenal duplication cysts is abdominal pain with or without nausea or vomiting. The most common complication is pancreatitis. Differential diagnoses of pancreatitis, hepatitis, cholestasis, or intussusception should include duplication cyst of the duodenum.
背景
十二指肠重复囊肿较为罕见。本研究通过文献复习描述了一例十二指肠重复囊肿病例，并评估了其临床特征。
方法
报告一例十二指肠重复囊肿病例，并对 1999 年至 2009 年间在 PubMed 上发表的相关文献进行了回顾。分析了临床表现、诊断检查和治疗方法。
结果
包括本报告在内，文献中有 38 篇引文充分描述了 47 例十二指肠重复囊肿病例。19 例（40.4%）在 10 岁以前发现，而 10 例（21.3%）在第二个十年发现。其余 18 例患者（38.3%）年龄大于 20 岁。病例数量随年龄增长而减少。总体而言，80%的病例表现为腹痛，53%伴有胰腺炎。
结论
十二指肠重复囊肿最常见的症状是腹痛，伴有或不伴有恶心或呕吐。最常见的并发症是胰腺炎。胰腺炎、肝炎、胆汁淤积或肠套叠的鉴别诊断应包括十二指肠重复囊肿。
