The presence of free intraperitoneal gas usually warrants emergent surgery. In rare instances, however, non-surgical conditions such as jejunal diverticulosis can cause pneumoperitoneum and do not require intervention.
The objective of this article is to provide the computed tomography (CT) scan findings of jejunal diverticulosis causing pneumoperitoneum. The article will also discuss other non-surgical causes of spontaneous pneumoperitoneum to increase awareness and avoid unnecessary surgery.
We describe a case of recurrent pneumoperitoneum due to jejunal diverticulosis in which the patient remained asymptomatic and free of complications with repeated evaluations in the emergency department over the course of 18 months.
Although spontaneous pneumoperitoneum due to jejunal diverticulosis is a rare finding, when it does occur, this condition must be distinguished from other forms of pneumoperitoneum to avoid unnecessary surgery. CT scan findings of multiple rounded, variably sized jejunal outpouchings filled with oral contrast are helpful in diagnosing jejunal diverticulosis and confirming the decision for conservative management of the patient.
腹腔内游离气体的存在通常需要紧急手术。然而，在罕见情况下，诸如空肠憩室病等非手术性疾病可导致气腹，且无需干预。
本文的目的是提供导致气腹的空肠憩室病的计算机断层扫描（CT）表现。本文还将讨论自发性气腹的其他非手术原因，以提高认识并避免不必要的手术。
我们描述了一例因空肠憩室病导致复发性气腹的病例，在18个月的病程中，患者在急诊科经多次评估后仍无症状且无并发症。
尽管空肠憩室病导致的自发性气腹是一种罕见发现，但当它确实发生时，必须将这种情况与其他形式的气腹相区分，以避免不必要的手术。多个圆形、大小不一且充满口服造影剂的空肠憩室的CT扫描表现有助于诊断空肠憩室病，并确认对患者进行保守治疗的决定。
