Endometriosis can affect 10% of women at reproductive age. Of those, 5.3% to 12% will have endometriosis affecting the bowel. Although outcomes after surgery for severe endometriosis affecting the bowel have previously been studied and have shown improvement in generic quality of life indices and sexual function, few studies have evaluated bowel function or symptoms specific to endometriosis. Our aim was to determine the quality of life after radical excision of rectovagina endometriosis compromising the bowel.

Women with severe rectovaginal endometriosis compromising the bowel.


Comparison of preoperative data with a 2-, 6-, and 12-month follow-up was made for consecutive patients who underwent surgery for endometriosis with bowel involvement. The main outcome measures were quality of life using the Endometriosis Health Profile 30 and EuroQol-5 dimension questionnaires. Bowel symptoms were measured using the Gastrointestinal Quality of Life Index. Dysmenorrhea, dyspareunia, dyschezia, and chronic pain were measured using a visual analogue scale. To compare preoperative and postoperative scores, a Freidman test was performed followed by a preoperative and 12-month postoperative Wilcoxon signed-rank test. A Mann-Whitney U test was used to compare the results between those who had pelvic clearance and those who did not.


In total, 137 patients had surgery, of which 100 completed follow-up to 12 months. The serious perioperative and postoperative complication rate was 7.3%. The results show significant improvement in almost all variables measured (p < .01). At 12 months patients who had a pelvic clearance (hysterectomy with bilateral salpingo-oophorectomy) had significantly less pain with better bowel function. Additionally, they had higher quality of life scores and greater satisfaction with their treatment. There was no significant difference between any postoperative variables tested regardless of the type of bowel surgery.


Severe rectovaginal endometriosis compromising the bowel can be treated surgically with experienced combined gynecologic and colorectal input with a low serious complication rate. Surgery by an experienced multidisciplinary team results in significant improvement in pain, sexual function, and quality of life up to 1 year postoperatively. Pelvic clearance improves outcome and patients should be counseled accordingly. There is no difference in outcome between the types of bowel surgery undertaken as long as all visible/palpable endometriosis is removed.
