Gangrenous Cholecystitis Secondary to Pneumatosis Intestinalis and Portal Venous Gas: A Case Report

Pneumatosis intestinalis (PI) and portal venous gas (PVG) are pathological conditions suggesting serious underlying diseases such as intestinal ischemia, intestinal wall infarction, and necrotizing enterocolitis. Therefore, early detection, comprehensive management, and timely treatment of the underlying disease are important for improving outcomes. We experienced a case of a patient who developed gangrenous cholecystitis secondary to PI and PVG. In this case, it was suggested that gangrenous cholecystitis may have been induced by retrograde infection due to the proliferation of intestinal bacteria and increased intestinal pressure caused by the reduced intestinal peristalsis due to PI and PVG. Herein, we report the successful treatment of this case with a literature review.
