ABSTRACT
Colorectal carcinoma emergencies during pregnancy are exceptionally rare. Three women 38, 31 and 36 years old, in the third trimester of gestation received treatment, respectively, for acute abdomen due to perforation of rectal carcinoma, ileus due to a sigmoid tumor, and deep venous thrombosis (DVT) from a cecal tumor compromising the right iliac vein. In the first two patients urgent cesarean sections were carried out with Hartmann's procedure and a loop colostomy was performed to resolve the ensuing intraabdominal sepsis and ileus, respectively. In the third patient, a cesarean section was carried out to treat the underlying DVT more aggressively, while right colectomy was postponed for three weeks. Restoration of the alimentary tract was achieved two months later in the first case, while in the second and third cases total colectomy due to familial polyposis and right colectomy were performed three weeks after the cesarean section. An overview of the clinical features, diagnostic pitfalls and therapeutic approaches to manage complications of colorectal cancer during pregnancy are discussed.
