Pneumatosis intestinalis (PI) is the presence of intraluminal gas within the wall of the intestine. As a marker for bowel injury owing to mucosal injury, PI may herald a severe underlying disease process in patients without a significant medical history. In other cases, PI is a benign process, and expectant management is appropriate. Here, we present the first reported case of pneumatosis associated with postoperative abscess after appendectomy and its successful management. Then, we describe the pathophysiology of pneumatosis and review the literature regarding its origin and management.
肠气肿（PI）是指肠壁内出现腔内气体。由于黏膜损伤，PI 是肠损伤的标志，可能预示着无明显病史的患者存在严重的潜在疾病过程。在其他情况下，PI 是一种良性过程，适当的保守治疗即可。在此，我们报告首例阑尾切除术后脓肿相关肠气肿的病例，并成功进行了治疗。然后，我们描述了肠气肿的病理生理学，并复习了其起源和治疗的相关文献。
