Abstract
Pneumatosis cystoides intestinalis (PCI) is a relatively rare disease in which multilocular or linear pneumatic cysts develop under the mucosa or serosa of the intestinal wall. We conducted a retrospective analysis to investigate the clinical characteristics of 68 patients with PCI. Hepatic portal venous gas (HPVG) was present in 9 patients, 8 of which had underlying intestinal tract necrosis. In most patients, PCI was mild and asymptomatic and resolved spontaneously. The main treatment strategy for PCI is conservative therapy. However, in cases complicated by HPVG, the presence of underlying intestinal tract necrosis must be considered in order to promptly determine whether emergency surgery is required.
