Surgical treatment of rectovaginal endometriosis with rectal involvement

Is Complete Excision Always Enough? A Quality of Sexual Life Assessment in Patients with Deep Endometriosis

Background and Objectives: The aim of this study was to find the factors associated with the severe impairment of QoSL and the factors associated with a better score in QoSL, as well as the evaluation of pain symptoms and QoSL after the complete and incomplete excision of rectovaginal nodules. Materials and methods: The present prospective study was conducted in a single tertiary center for endometriosis where 116 patients underwent laparoscopic surgery for deep endometriosis during a 3-year period. The goal of the intervention was to excise all endometriotic implants while conserving the rectum. Intraoperative findings were recorded after the intervention, and the patients were classified according to the ENZIAN classification and rASRM scores. QoSL was assessed using the EHP-30 Module C (QoSL Score). Results: When comparing the mean scores before and 2 years after the surgery, a highly significant improvement was found for QoSL and dysmenorrhea (p < 0.0001). The complete excision of rectovaginal nodules led to a significantly better QoSL and lower dyspareunia (p < 0.0001) than incomplete resection (p < 0.02). Conclusions: This prospective study proves that the complete laparoscopic excision of all endometriotic implants improved the QoSL and decreased the pain score of dyspareunia. Incomplete rectovaginal nodule excision was correlated with a poorer QoSL and a lower improvement of dysmenorrhea, dyspareunia, and chronic pelvic pain scores than complete excision.

Choosing the right surgical technique for deep endometriosis: shaving, disc excision, or bowel resection?

Deep endometriosis (DE) remains the most difficult endometriotic entity to treat. Medical treatment for DE can reduce symptoms but does not cure the disease, and surgical removal of the lesion is required when lesions are symptomatic, impairing bowel, urinary, sexual, and reproductive functions. Although several surgical techniques such as laparoscopic bowel resection, disc excision, and rectal shaving have been described, there is no consensus regarding the choice of technique or the timing of surgery. Our review of publications reporting results and complications of surgery for rectovaginal DE reveals a relatively higher complication rate after bowel resection compared with shaving and disc excision, especially for rectovaginal fistulas, anastomotic leakage, delayed hemorrhage, and long-term bladder catheterization. Data show that shaving is feasible even in advanced disease. The risk of immediate complications after shaving and disc excision is probably lower than after colorectal resection, allowing for better functional outcomes. The presumed higher risk of recurrence related to shaving has not been demonstrated. For these reasons, surgeons should consider rectal shaving as a first-line surgical treatment of rectovaginal DE, regardless of nodule size or association with other digestive localizations. When the result of rectal shaving is unsatisfactory (rare cases), disc excision may be performed either exclusively by laparoscopy or by using transanal staplers. Segmental resection may ultimately be reserved for advanced lesions responsible for major stenosis or for several cases of multiple nodules infiltrating the rectosigmoid junction or sigmoid colon.

Deep infiltrating endometriosis affecting the urinary tract-surgical treatment and fertility outcomes in 2004-2013

Urinary tract endometriosis (UTE) is a rare form of deep infiltrating endometriosis. We studied the operative treatment of UTE and evaluated postoperative recurrences and fertility outcomes. This is a retrospective cohort study of 53 women who underwent operative treatment for UTE in 2004–2013 at Helsinki University Hospital, and were followed-up until the end of 2014. The data were gathered from the hospital’s electronic database. The main outcome measures were complications, reoperations, postoperative pregnancies, and deliveries. Preoperative diagnosis was accurate in 72 % with bladder endometriosis and in 93 % with ureteral disease. Thirty-one (58 %) of the 53 operations were performed via laparoscopy. Postoperative complications requiring re-intervention occurred in five cases (9 %). Five reoperations were performed in four cases due to endometriosis recurrence, only two due to recurrence of UTE (4 %). Twenty-eight women wished for pregnancy; 18 (64 %) of them conceived. Infertility treatment was needed in 20 (71 %) cases. Twelve (75 %) women delivered via cesarean section; intraoperative difficulties occurred in ten (83 %). The complication rate with UTE operations is acceptable and recurrences are rare. Infertility is common, but 57 % of those who wished for a child succeeded. A majority of the deliveries involved unplanned and complicated cesarean section.
