Pathogenic mechanisms of intestinal pneumatosis and portal venous gas: should patients with these conditions be operated immediately?

Abstract: We aimed to histologically observe portal venous gas (PVG)-causing intestinal pneumatosis (IP) and evaluate pathogenic mechanisms and therapeutic strategies, including decisions on whether emergency surgery should be performed. Autopsy was performed in two cases of nonocclusive mesenteric ischemia (NOMI). We directly histologically observed the pathogenic mechanisms of IP caused by gas-producing bacteria and IP considered to be caused by mechanical damage to the intestinal mucosa. IP can be classified hypothet… Show more

“…Intestinal pneumatosis is an early sign that may precede clinical signs of necrotizing enterocolitis in neonates . The intramural gas is a byproduct of the metabolism by bacteria penetrating the mucosal defense . This intramural gas passes into the portal vein and leads to the formation of portal venous gas .…”

“…A maioria dos casos de PI apresenta--se de forma assintomática 16,17 . A sua patogénese não está completamente estabelecida, no entanto, pode ser causada por isquemia do intestino, trauma mecânico, doença intestinal inflamatória / autoimune, neoplasias do intestino, infeção do intestino, imunossupressão induzida por drogas e doença pulmonar obstrutiva crónica 16,20 . Em alguns casos, a PI é um achado incidental, ao passo que, em outros, ela anuncia uma condição intra-abdominal com risco de vida 19,20 .…”

A incidência da PI parece estar a aumentar 18 ; novos medicamentos e procedimentos cirúrgicos têm sido relatados como os responsáveis deste aumento 18,20 .…”
