Objective: To report the clinical characteristics and treatment courses of pneumatosis cystoides intestinalis(PCI) after lung transplantation(LT). Methods: We included all cases of PCI after LT from March 2017 to June 2021 in China-Japan Friendship Hospital. In addition to our cases, we searched literatures published in Chinese and English languages using China National Knowledge Infrastructure (CNKI), Wanfang Data and PubMed/MEDLINE with the search terms"pneumatosis intestinalis"and"lung transplantation". The clinical characteristics and treatment courses of all cases were summarized and analyzed. Results: Three cases of PCI occurred after LT in this study, with an incidence of 0.804% (3/373). Thirteen related literatures were retrieved, with 51 cases enrolled. The median age of the 54 patients was 55.4 years (22-79 years), with 33 males and 21 females. 64.81% (35/54) of the 54 patients underwent LT for interstitial lung disease and 90.74% (49/54) underwent bilateral LT. Twenty-two cases(40.7%) were asymptomatic when PCI occurred. Thirty-eight cases (38/54,70.37%)had involvement of ascending colon, and 35 cases(35/54,64.81%)had involvement of transverse colon. Forty-three cases(43/54, 79.63%) were treated conservatively. The average interval between transplantation and PCI was 210 (5-2 495) days. Conclusion: PCI is a rare complication after lung transplantation, most often occurring in the colon. Most patients were asymptomatic and could improve by conservative treatments.
目的： 对肺移植术后合并肠气囊肿症（PCI）的临床特点和诊治情况进行总结分析。 方法： 回顾性分析2017年3月至2021年6月中日友好医院肺移植术后所有并发PCI患者的临床资料，并以“肠气囊肿症、肺移植”为中文检索词，“Pneumatosis Intestinalis、Lung Transplantation”为英文检索词检索中国知网、万方、Pubmed数据库相关文献，对入组患者的临床特征、诊疗经过及转归进行归纳分析。 结果： 本中心肺移植术后发生3例PCI，发病率为0.804%（3/373）。另检索出相关文献13篇，入组病例51例。54例患者中男33例，女21例，中位年龄为55.4岁（22~79岁）。54例患者中64.81%（35/54）因肺纤维化进行肺移植，90.74%（49/54）进行双肺移植。发生PCI时40.7%（22/54）无症状，70.37%（38/54）升结肠受累，64.81%（35/54）横结肠受累，48.1%（26/54）合并气腹，79.63%（43/54）给予保守治疗。从肺移植到诊断PCI的中位时间为210（5~2 495）d。 结论： PCI是肺移植术后少见的并发症，最常发生于结肠，无症状者多见，多经保守治疗病情可好转。.
