Fascia suturing during cesarean may be linked to the later occurrence of cesarean scar endometrioma.

The most common type of abdominal wall endometriosis is cesarean scar endometriosis (CSE), defined as the presence of endometrial tissue outside the uterine cavity. Multiple hypotheses can explain the implantation theory. Endometrioma are most commonly located on the fascia-muscles layer and on both side corners of the cesarean-section scar. By reviewing the surgical techniques used in the cesarean section, we hypothesize that the type of suture material, the knot in itself, and the angiogenesis could be factors that influence CSE development.
