REPRODUCTIVE ENDOSURGERY
Role of laparoscopy and hysteroscopy in infertility:
- Primary evaluation- Laparoscopy – NO1
- Hysteroscopy – MAYBE2
- In women undergoing IVF
- Secondary evaluation- Unsuccessful HSG or SIS
- In the patient with unexplained infertility
- unwilling to consider ART
- has pain as a major symptom
- has failed multiple OI/IUI, or IVF3
- Primary treatment
- Secondary treatment- To enhance IVF outcomes
- Ovarian preservation

ENDOMETRIAL POLYPS
• Perez-Medina T et al, 2005
- RCT of 215 women with endometrial polyp undergoing IUI
- Hysteroscopic polypectomy (n=107) vs. endometrial biopsy (n=109)
- Pregnancy rate was higher (51 vs. 25%)
- More than ½ of women conceived spontaneously within 3m PO
- Independent of size of the polyp

SUBMUCOUS FIBROIDS
• Casini et al, 20065
- RCT of women with infertility limited to a single fibroid of ≤4cm
- SM (n=52), SM-IM fibroid (n=42)
- Pregnancy rates were higher
- 43% vs. 27% in the SM group
- 36% vs. 15% in the SM-IM group
• Intrauterine adhesions, 7.5-78%6,7
• Surgical considerations
- Complexity (number, size, depth, location)
- Pretreatment with GnRH agonist
- resectoscope vs. morcellator, warmed irrigant
- 2-stage procedure, abdominal approach
- 2nd look office hysteroscopy or SIS5

UTERINE SEPTA
• Mollo A et al, 20097
- unexplained infertility with uterine septum
- Higher pregnancy and live birth rates (34 vs. 19%)
• Surgical considerations
- Complexity - Thickness
- Length of septum
- Incision vs. resection
- Concurrent laparoscopic guidance
- Staged procedure
- Pre-treatment with GnRH agonist6

INTRAUTERINE ADHESIONS
Johary et al, 20148
- Systematic review of 28 studies
- Pregnancy rate 40 - 80%, live birth rate of 30 – 70%
Pregnancy rates are higher9, recurrence rates are lower10 with mild vs. severe adhesions
Considerations
- Cold scissors, concurrent laparoscopy
- Barriers (balloon > IUD > hyaluronic gel)11
- Estrogen therapy
- Second-look office hysteroscopy or SIS
- Risk of morbidly adherent placenta ~10%

• Duffy et al, 201412
- Decreased overall pain (OR 6.58, 95%CI 3.31-13.10)
- Increased live birth rate (OR 1.94, 95%CI 1.20-3.16)
- NNT=8 (95%CI 5-32)13,14
• Pregnancy rates with excision = electrocoagulation15
• Opoien et al, 201116
- Improved outcomes of subsequent IVF
- Offer lap to infertile women with pain suggestive of mild endometriosis

• Hart et al, 200817
- Cystectomy vs. drainage and coagulation:- Lower recurrence of endometrioma, pain
symptoms, need for further surgery
- Higher spontaneous pregnancy rate in women with infertility (CI 5.21, 95%CI 2.04-13.29)
• Tang et al, 201318
- Unilateral cystectomy prior to IVF - AFC, # dominant follicles, # oocytes retrieved were
decreased in operated ovaries vs. intact ovaries
- These differences were greater in cysts ≥4cm vs <4cm, even after accounting age and AFC
- Size of cyst correlated with incidence of <4 oocytes retrieved from operated ovary

• Incidence28: - 61% after 1, 100% after 3 C/S
• Risk factors29:- low incision, through cervical tissue
- non-full thickness, locking closure
- angulation due to RF, adhesions
• Symptoms- Postmenstrual AUB
- Pelvic pain
- Secondary infertility
- Persistent hydrometra
• Laparoscopic repair- Excision of the scar tissue from the edges
- 2-layer closure of the defect
• Donnez et al, 201730
- Prospective observational study, N=38, with <3mm myometrium
- Myometrial thickness increased - 1.43 ± 0.7 to 9.62 ± 1.8mm
- 91% symptom free
- 44% of infertile women conceived
• Hysteroscopic alternative- Risk of uterine perforation, bladder injury
- Does not increase myometrial thickness
