Spontaneous Sigmoid Colon Perforation Based on Endometriosis in Term Pregnancy Case Report

The case report describes a woman with acute, spontaneous sigmoid colon perforation based on deep endometriosis in advanced stage of pregnancy. The 33-yearold white woman was admitted to our clinic at 37+6 weeks of pregnancy with symptoms of increasing abdominal pain successively changing the site of maximum. Due to suspicion of acute appendicitis, acute caesarean section, sigmoid resection and end-to-end anastomosis, appendectomy was performed. Spontaneous perforation associated with intestinal endometriosis in pregnancy is scarcely reported, some seven cases have been published in the English literature. To the best of our knowledge, this is the second case report of sigmoid colon perforation due to endometriosis during pregnancy.
