Abstract PURPOSE: Endorectal ultrasound was performed in patients with endometriosis to evaluate the role of this technique for rectal wall involvement and to evaluate the position of preoperative diagnosis in the operative management of rectal endometriosis. METHODS: Sixteen patients with suspected fixation of endometriomas to the rectal wall during bimanual examination were included in the study. Endorectal ultrasound was performed using a real time unit with a 7.5 MHz endorectal transducer. The probe was introduced via a rectoscope into the rectum up to the rectosigmoid. RESULTS: Endometriosis was confirmed histopathologically in all patients. In six patients rectal wall involvement was diagnosed, in two patients endometriomas were adjacent to the rectal wall, and in eight patients rectal wall involvement could be excluded. Preoperative diagnosis was confirmed in all patients during operation. Laparotomy was performed in those patients with preoperatively diagnosed rectal wall involvement, whereas the remaining patients were treated laparoscopically. Endometriomas with rectal wall involvement were treated in five of six patients with resection of the affected bowel predominantly by low anterior resection. CONCLUSIONS: Preoperative endorectal ultrasound is a reliable technique to visualize perirectal endometriomas and to assess rectal wall involvement. Based on preoperative endosonographic diagnosis, an operative management was established with laparotomy and resection of the affected bowel in cases of rectal wall involvement.
