A new article published in the Acta Obstetricia et Gynecologica Scandinavica evaluated the risk of bowel obstruction during in vitro fertilization IVF treatment in women with deep infiltrating endometriosis. This retrospective cohort study enrolled 76 women with bowel endometriosis who were treated conservatively and underwent IVF treatments. It was observed that 11.8 of these women experienced severe worsening of their bowel related symptoms with two patients presenting with colon ileus. On the other hand one woman had no previous diagnosis of endometriosis before she presented with sub occlusion of the bowel during IVF. In all cases IVF treatments were discontinued. The findings of this study indicated that bowel endometriosis increases the risk of complications during IVF treatment. Although this finding contradicted several publications the article clarified that this study population was different in that none of these women had had previous surgery for bowel endometriosis. It was stated that in 88 of the cases women completed fertility treatment without the need for surgery.
