RESUMEN
We present the case of an 83-year-old male, with a past medical history of benign pneumoperitoneum secondary to pneumatosis intestinalis which evolved for a number of years with periodic follow-ups. The patient comes to the Emergency Room with sintomatology of intestinal obstruction. Urgent surgical management is decided, an exploratory laparotomy is performed where an intestinal obstruction secondary to pneumatosis intestinalis, with loss of structure of the intestinal wall as visualized in the images, is determined; therefore resection of the affected small intestine segment and primary anastomosis are performed. The pathology report confirms the diagnosis. The patient progresses favorably during the postoperative period and is currently asymptomatic after 12 months.
