Discoid resection involves excision of the diseased rectal wall at the same time as endometriotic lesions (19).
Rectal suture is then performed with separate stitches or a universal stapler. The advantage of this technique is that it also preserves the posterior part of the rectum and is therefore associated with maintenance of urinary function, much like shaving.
However, patients must be informed that they are at greater risk of rectovaginal fistula, and hence the need for a temporary stoma, in 5-10% of cases according to different studies (21, 22).
In order to avoid this risk, some teams place a protective stoma intraoperatively. The high rates of fistula justify use of this technique being used only when shaving is not an option (19).
