Abstract：
BACKGROUND: Pneumatosis intestinalis is a radiological finding characterized by the presence of gas in the bowel wall that is associated with multiple entities. Our aim is to know its incidence in lung transplant patients, its physiopathology and its clinical relevance.
METHODS: A search of patients with pneumatosis intestinalis was performed in the database of the Lung Transplant Unit of our hospital. The presence of pneumatosis after transplantation was confirmed in all of them and relevant demographic, clinical and imaging variables were collected to evaluate its association and clinical expression, as well as the therapeutic approach after the findings.
RESULTS: The incidence of pneumatosis intestinalis after lung transplantation in our center was 3.1% (17/546), developing between 9 and 1270 days after transplantation (mean, 198 days; median 68 days). Most of the patients were asymptomatic or with mild symptoms, without any major analytical alterations, and with a cystic and expansive radiological appearance. Pneumoperitoneum was associated in 70% of the patients (12/17). Conservative treatment was chosen in all cases. The mean time to resolution was 389 days.
CONCLUSIONS: Pneumatosis intestinalis in lung transplant patients is a rare complication of uncertain origin, which can appear for a very long period of time after transplantation. It has little clinical relevance and can be managed without other diagnostic or therapeutic interventions.

摘要：
背景：肠气病是一种放射学发现，其特征是肠壁中存在与多个实体相关的气体。我们的目的是了解肺移植患者的发病率，其病理生理学及其临床相关性。
方法：在我院肺移植病房的数据库中进行了肠积气患者的检索。在所有这些患者和相关的人口统计学中都证实了移植后存在肺炎，收集临床和影像学变量以评估其相关性和临床表现，以及发现后的治疗方法。
结果：我们中心肺移植后肠积气的发生率为3.1％（17/546），移植后9至1270天发展(平均，198天；中位数68天）。大部分患者无症状或症状轻微,没有任何重大的分析修改，具有囊性和扩张性放射学外观。70％的患者发生气腹（12/17）。所有病例均选择保守治疗。平均解决时间为389天。
结论：肺移植患者的肠型肺炎是一种罕见的病因不明的并发症，这可以在移植后很长一段时间内出现。它几乎没有临床意义，可以在没有其他诊断或治疗干预的情况下进行管理。
