Surgical Removal of Endometriosis: When Is It Worth the Risk? Tommaso Falcone, M.D. Professor and Chair Obstetrics and Gynecology Cleveland Clinic
LEARNING OBJECTIVES At the conclusion of this presentation, participants should be able to: Assess the outcome (pain relief or pregnancy) of surgical treatment for endometriosis. Discuss different surgical techniques used to treat endometriosis.
DISCLOSURE Nothing to disclose
Symptoms & Signs of advanced endometriosis • Chapron et al 2005 • “Presurgical diagnosis of posterior deep infiltrating endometriosis based on a standardized questionnaire” • Painful defecation during menses • Severe dyspareunia • Previous surgery for endometriosis
Diagnostic work-up • History ( dysmenorrhea, dyspareunia & noncyclic pelvic pain) • Physical exam: adnexal mass, non mobile uterus or cul-de-sac nodularity. • CA-125 • Meta-analysis • Sensitivity of 28 % showed a specificity of 90% • Sensitivity of 50% showed a specificity of 72%
Role of Imaging • Transvaginal ultrasound has a high sensitivity & specificity in the diagnosis of ovarian endometriotic cyst • MR & CT have no added advantage • Trans-rectal ultrasound may have some value for recto-vaginal endometriosis (Fedele et al Obstet & Gynecol 1998) • Imaging has a low sensitivity & specificity for non-ovarian endometriosis
Histologic Diagnosis • Mettler et al. JSLS 2003 • Histologic confirmation in visually identified endometriosis: 54% • “Red” lesions: 100% • “Black” lesions: 92% • “White” lesions: 31% • Sites: least probable on the ovary, bowel serosa, bladder peritoneum
Treatment Effect • 2 RCTs - Canadian study showed a treatment effect ( inclusion only of women age 20-39 years); Italian study showed no treatment effect. • Combine the studies for pregnancies over 20 weeks: 27% (treated) and 18% ( non-treated): NNT=12 ( 95% CI 6,112) • 20% prevalence of endometriosis • 60 diagnostic laparoscopies to get an extra pregnancy RCTs = randomized controlled trials; NNT = number needed to treat; CI = confidence interval
Moderate-Severe Endometriosis • Candiani et al. 1991 • 206 patients/15 studies: MFR, 3%; CPR, 47% • Luciano et al. 1992: MFR 6.7%; CPR 70% • Busacca et al. J Am Ass Gyn L 1999 • Prospective study: MFR, 2.4%; CPR 24 months, 57% • No RCT • Overall, surgery is not recommended for fertility alone; it can be considered for women under age 35 years. MFR = monthly fecundity rate; CPR = clinical pregnancy rate
Stage III and IV EndometriosisPagidas et al.Fertility and Sterility 1996
Stage III and IV Endometriosis • After initial unsuccessful operative procedure to restore fertility, in vitro fertilization – embryo transfer (IVF-ET) appears to be a superior alternative to re-operation.
Laser Laparoscopy vs. Expectant ManagementSutton et al. Fertil Steril 1994 • 74 women ( Stage I-III) • Prospective randomized double-blind • Significant pain relief compared to expectant management • Non-response rate was 38% • Results were poorest for stage I
RCT scope excision of endo • Abbott et al. F&S 2004 • RCT-placebo trial • Immediate surgery group- 80% response rate at 6 months • Far fewer stage I endometriosis • Delayed surgery group: 30% response rate at 6 months (placebo effect)
Audience Response Question # 1 Please use the text message function on your cell phone.
Success Rate in Teenagers • How do you define “success”? • Yeung et al. F&S 2011 • N=17; 47 % had repeat surgery within 2 years • None had endometriosis
Recurrence Rate • Sutton’s trial F&S 1994 • Follow-up (1 year) after RCT: Treated Group that Improved • 10% recurrence rate • Subsequent surgery showed endometriosis • Abbott et al. Human Reproduction 2003 • 135 patients; Kaplan –Meier survival curve • Average follow-up 3.2 years (range, 2-5 years) • 36% probability of further surgery • 32% had no endometriosis

Hysterectomy in Young Women (Less than 30 Years of Age) • Women under age 30 years (compared with women over age 40 years) • 80% felt that hysterectomy had “cured their pain” • 18% had residual symptoms of dyschezia • 18% persistent dysuria • 50% persistent dyspareunia • 56% had a “sense of loss”
Surgical vs. Medical Therapy • Recurrence rate after discontinuing medical therapy is very high. • Placebo rate is approximately 30%.
Prevention of Recurrent Pain • To be effective, you have to use suppressive therapy for long periods of time.
LUNA procedure • Latthe et al. 2007 Systematic Review • No evidence that LUNA adds value to conservative surgery for endometriosis associated pain LUNA = laparoscopic uterine nerve ablation
Robotic Surgery for Endometriosis- • 3 case reports and 1 comparative trial • Nezhat et al. F&S 2010 • N=78; mostly early stage disease; retrospective • Robotic time: 191 minutes • Standard laparosocpy: 159 minutes • No difference in outcome • Longer OR time and larger trocars OR = operating room
Excision versus Ablation • Pregnancy rates similar • Pain relief? • Healy et al. 2010 • Seems equivalent for early stage disease
Endometriosis:Persistence after TAH+BSO • Often seen when endometrial implants not excised • Aromatase expressed in endometriotic lesions • Conversion of adrenal androgens to estrogen locally TAH = total abdominal hysterectomy; BSO = bilateral salpingo-oophorectomy
Failure of Medical Management Persistent Bilateral Ureteral Obstruction Secondary to Endometriosis Despite Treatment with an Aromatase Inhibitor Bohrer et al. F&S 2008
Duodenum Lesion Ureter Aorta IVC
Rectosigmoid Endometriosis: • Significant bowel symptoms • Colonoscopy or barium enema normal • May show a stricture • Persistent disease after TAH+BSO is usually rectosigmoid endometriosis
