Antibiotics have been investigated as a mainstay treatment for PI. One regimen, which has proven to have some success, is metronidazole 500 mg per os (PO) three times daily (TID) for up to 3 months. It is theorized that antibiotics reduce the amount of gas produced by bacteria and alleviate obstructive symptoms.

Why does pneumatosis intestinalis occur?

Pneumatosis is found secondary to mucosal disruption presumably due to over-distention from peptic ulcer, pyloric stenosis, annular pancreas, and even to more distal obstruction. Disruption can also be caused by ulceration, erosions, or trauma, including the trauma of child abuse.

How common is pneumatosis intestinalis?

Pneumatosis intestinalis (PI) is defined as the presence of gas in the bowel wall [1–4]. This imaging finding is associated with numerous conditions, ranging from benign to life threatening [1–5].

Afterward, the doctor will restore blood flow to the areas affected by the volvulus.
