ENDOMETRIOSIS When and how to implement treatment

ENDOMETRIOSIS When and how to implement treatment

Francisco Carmona Hospital Clínic

ENDOMETRIOSIS TREATMENT It depends on the severity of symptoms the patient's desire for pregnancy the extent of disease the location of disease the age of the patient.

ENDOMETRIOSIS TREATMENT TREATMENT OBJECTIVES: - Symptom control - Increase fertility. - Recurrence prevention. - Endometriosis lesions.

Endometriosis Treatment Options Expectant Management Medical therapy Progestins Levonorgestrel-releasing intrauterine device Danazol GnRH analogues Oral Contraceptives Analgesics, NSAIDs Surgical therapy Conservative: retains uterus and ovarian tissue Definitive: removal of uterus and possibly ovaries Combination therapy Preoperative medical therapy Postoperative medical therapy

MEDICAL TREATMENT Improve patients - Increase QoL - Useful in patients with mild-moderate cases - Some medical treatments reduce the recurrence rate after surgery

MEDICAL TREATMENT - It is not a definitive cure for the disease

Endometriosis Treatment New options Hormonal treatments Aromatase inhibitors GnRH antagonists Selective progesterone receptor modulators Selective estrogen receptor modulators Selective ER-β agonists Non hormonal treatments Antiangiogenics Dopaminergic agonists Statins TNF α-blockers Infliximab Immunomodulators Pentoxifylline Anti COX-2 agents Peroxisome proliferator-activated receptor γ-ligands Anti-nerve growth factor inhibitor antibody Inducers of apoptosis

ENDOMETRIOSIS. Importance of presurgical staging OE 24 patients 16 patients 28 patients Adenomyosis 22 patients 30 patients 20 patients Hospital Clinic Results (january-july 2013) 30 patients DIE

ENDOMETRIOSIS SURGICAL TREATMENT PHILOSOPHY Conservative towards function Radical towards disease Tailor the surgery To respect patient desires

ENDOMETRIOSIS SOME IMPORTANT CONCEPTS - Not always a progressive/recurrent disease Indication for surgery is mainly clinical Diagnosis alone is not an indication for surgery!

ENDOMETRIOSIS SOME IMPORTANT CONCEPTS - The first surgery is the most important If incomplete, subsequent surgery will be more difificult

ENDOMETRIOSIS SOME IMPORTANT CONCEPTS It is increasingly recognized that endometriosis is one of the most challenges and difficult types of pelvic surgery a gynecologist may face Not all gynecologists/centers are adequately prepared to deal with all cases of DIE

ENDOMETRIOSIS SOME IMPORTANT CONCEPTS A decision has to be made according to: - Severity of disease found (both in the preoperative study and during surgery) - Adequacy of preoperative information and consent - Suitability of medical environment - Surgical skill and expertise - Level of postoperative care

ENDOMETRIOSIS SOME IMPORTANT CONCEPTS Intraoperative Decision: 1.- See-and-treat 2.- See-and-discuss 3.- See-and-refer

ENDOMETRIOSIS SOME IMPORTANT CONCEPTS IMPORTANCE OF PRESURGICAL STAGING: - Several localizations coexist - Previous surgeries: adhesions - Asymptomatic patients: - > 50% hydronephrosis - ICGON: 60% hydronephrosis patients were asympto. - Difficult localizations - Appendicular (4% endometriosis) - ICGON: 5% (100% multiple localizations).

ENDOMETRIOSIS SOME IMPORTANT CONCEPTS ADVANTAGES OF PRESURGICAL STAGING: Non invasive Specialized team available Informed consent No incomplete surgeries: recurrences

TVUS: 1 st line modality Readily available Well accepted Cost effective Time effective!s, S; LR+, LR-

Specific Indications for MRI Some specific localizations or cases Ureter Sigmoid after diagnosis of rectal nodule Right bowel Parametrial affectation USL Extrapelvic locations Pretreatment in UAE or HIFU Adenomyosis (?) Differentiation of endometrioma from Hemorragic or mucinous cyst Differentiation of decidualized cyst from cancer

General Surgical Strategy 1 st Step TO KNOW DISEASE SEVERITY To explore the whole abdominal cavity " Visible disease " Retraction/Adhesion " Anatomic distortion

General Surgical Strategy 2 nd Step EXPOSITION " Mobilization small bowel " Mobilization uterus " Adhesions disection " Sigma liberation " Sigma Suspension (if needed) " Ovarian Suspension (if needed)

General Surgical Strategy 3 rd Step RECTAL DISECTION Ureter Disection (if needed) Start laterally From healthy areas to the disease

General Surgical Strategy 4 th Step NODULE DISECTION " Disection between nodule and rectum - Most times, disease in the genital side " To test integrity (Safety tests) - Bubble test - Methilen Blue / Iodine

General Surgical Strategy 5 th Step FISTULA PREVENTION Omentoplasty Sealants Drain

Specific Surgical Strategy Bowel To decide among shaving/discoid resection and segmental resection

Specific Surgical Strategy Bowel To decide among shaving/discoid resection and segmental resection There are no evidence based criteria to help us on that decision

Specific Surgical Strategy Bowel - Segmental resection - Discoid resection/shaving - Multiple lesions - Stenosis - % Circumference >40% - Mucous or submucous infiltration - Sigmoid localization (Leak %: 1%) - Single lesion - No Stenosis - % Circumference <40% - No Mucous or submucous infiltration - Rectumlocalization (Leak %: 5-15%) Systematic ileostomy not indicated

Specific Surgical Strategy Bowel Ileo cecal area/appendix: special case 4-5% of DIE cases Risk of obstruction Always look at More than two lesions

Specific Surgical Strategy Bladder Complete excision is mandatory as associated with symptomps resolution and low recurrence Shaving, mucosal skinning and partial cystectomy are adequate depending on size an infiltration. Preoperative cistoscopy is mandatory

Specific Surgical Strategy Bladder Two layer closure technique is used Catheter in place for 10-14 days Ureteral catheter in place if ureteric resection or trigone afectation

Specific Surgical Strategy Ureter Intrinsinc afectation is not frequent Resection: anastomosis; reimplatantion Extrinsinc afectation is common, maninly in the distal third In rectovaginal DIE ureters are tipically pulled medially and have to be dissected

Specific Surgical Strategy Ureter Ureter must be checked preoperatively in cases of rectovaginal endo or extensive disease Ureter must be always seen during surgery Uni or bilateral ureterolysis is almost always needed in rectovaginal surgery

Specific Surgical Strategy Ureter We do not systematic preoperative ureteral stenting Indications for ureteral stent are: Ureterohydronephrosis (pre) Previous ureteral lesion (pre) Ureteral dilatation not previously recognized Ureteral injury or resection Too much disection

Specific Surgical Strategy Endometrioma Ovarian Cystectomy: Ovarian Tissue adjacent to the cyst wall Endometriomas 58.7% Other benign cysts: 5.4% (p < 0,001)

OVARIAN ENDOMETRIOMA SURGERY Pro-SURGERY Pro-ART Symptoms Yes No Age Young Old Ovarian Reserve Normal Low Previous surgery No Yes Cyst size Big Small Risc of malignancy Yes No

TAKE HOME MESSAGES - Taylor the treatment!!! - Medical treatment may control symptoms. - Adequate presurgical staging is mandatory - Surgery requires specialization

Endometriosis and Infertile Woman Rationale Symptoms Pelvic pain of endometriosis or infertility TVUS with Bowel Prep AMH, FSH FSH Pain < 7 (VAS) No Bowel Obstrucion No Ureteral Obstruction Pain >= 7 (VAS) or Bowel Obstrucion or Ureteral Obstruction Ovulation Inducion (normal tubal patency) IVF Low AMH > 30yo Normal AMH < 30yo Cryopreservation Surgery Surgery Ovarian Induction - IVF ET

Deep Infiltrating Endometriosis DIE: Endometriosis infiltrating >5mm under peritoneal surface bladder 5 localizations: Utero-sacral ligaments vagina ureter Posterior DIE is the more frequent form, including USL, uterine torus, the posterior vaginal wall and the anterior rectal wall. bowel Koninckx et al.
