Bowel endometriosis: Colorectal surgeon’s perspective in a multidisciplinary surgical team

Figure 1 Transvaginal ultrasound image, sagittal view. A: Hypoechoic nodule in the rectovaginal septum measuring 1 cm × 0.9 cm (arrow). The nodule obliterates the pouch of Douglas, invades the anterior rectal wall, and causes anatomical distorsion (dotted arrow); B: A large hypoechoic retrocervical nodule affecting the rectosigmoid colon is seen (arrow). Note the typical “indian headdress sign”, indicating deep endometriosis into the bowel wall.
