Laparoscopic treatment of hydrosalpinx: factors affecting pregnancy rate

STUDY OBJECTIVE: To evaluate the efficacy of laparoscopic surgery in a series of women with hydrosalpinx. DESIGN: Prospective, observational study (Canadian Task Force classification II-2). Setting. University-affiliated hospital. PATIENTS: Sixty-one women undergoing bilateral neosalpingostomy and restoration of tubal ovarian anatomy laparoscopically, and followed for 24 months. INTERVENTION: Video-controlled operative laparoscopy using standard four-puncture technique. MEASUREMENTS AND MAIN RESULTS: During 24-month follow-up, cumulative intrauterine pregnancy rates at 6-month intervals were 6.8%, 13.6%, 20.5%, and 20.5% for patients with only distal tubal obstruction and 12%, 23%, 29%, and 29% for those with mild degree of tubal disease and periadnexal adhesions. Miscarriage rate for intrauterine pregnancies was zero in both groups. CONCLUSION: Operative laparoscopy seems to be an effective treatment for hydrosalpinx in terms of pregnancy outcome.     

Laparoscopic management of hydrosalpinges before in vitro fertilization-embryo transfer: salpingectomy versus proximal tubal occlusion

OBJECTIVE: To compare ovarian response and IVF-ET cycle outcome in patients with hydrosalpinges managed by either laparoscopic salpingectomy or proximal tubal occlusion. DESIGN: Retrospective analysis. SETTING: Tertiary-care assisted reproductive technology program. PATIENT(S): One hundred four consecutive fresh IVF-ET cycles in 94 patients with tubal-factor infertility. INTERVENTION(S): Laparoscopic salpingectomy (group 1: 35 cycles) or bipolar proximal tubal occlusion (group 2: 17 cycles), controlled ovarian hyperstimulation, and IVF-ET. Control groups consisted of both tubal-factor patients without hydrosalpinges (group 3: 37 cycles) and those with prior bilateral tubal ligation for sterilization (group 4: 15 cycles). MAIN OUTCOME MEASURE(S): Uterine artery Doppler flow, controlled ovarian hyperstimulation response, and implantation and clinical pregnancy rates. RESULT(S): There were no differences in mean uterine artery pulsatility indices or ovarian response among any of the groups. A trend toward a higher cycle cancellation rate in group 1 did not approach statistical significance. Clinical pregnancy and implantation rates were not significantly different between group 1 (57.1%, 29.2 +/- 5.9%, respectively) and group 2 (46.7%, 19.4 +/- 6.1%, respectively) or compared with those of controls. CONCLUSION(S): [1] Management of hydrosalpinges by laparoscopic salpingectomy or bipolar proximal tubal occlusion yielded statistically similar responses to controlled ovarian hyperstimulation and IVF-ET cycle outcome. [2] The latter approach may be preferable in patients who present with dense pelvic adhesions and easy access only to the proximal fallopian tube.     

In vitro fertilization with concurrent pelvic reconstructive surgery

The recent advent of ultrasound-guided follicular aspiration by various approaches now allows access to ovaries previously deemed inaccessible by laparoscopy; however, a small group of candidates for in vitro fertilization and embryo transfer (IVF-ET) require laparotomy for associated gynecologic disorders. Twenty-five IVF-ET cycles at the time of laparotomy were compared with 309 IVF-ET cycles in which oocytes were retrieved laparoscopically. Five pregnancies occurred in the IVF-ET cycle with laparotomy and one pregnancy occurred spontaneously following microsurgical tubal reconstruction. The pregnancy rate per embryo transfer was 25% in the laparotomy IVF-ET patients compared with 15.4% for the laparoscopy IVF-ET group. Obvious advantages of combining IVF-ET and pelvic reconstructive surgery include a single anesthesia exposure and economic benefits. Patients with a long history of infertility undergoing tubal reconstructive surgery may be offered combined IVF-ET. Extended anesthesia exposure with pelvic surgery demonstrated no adverse effects on the pregnancy rate.     

Cost analysis of tubal anastomosis by laparoscopy and by laparotomy

STUDY OBJECTIVE: To compare the costs of tubal anastomosis performed by laparoscopy and by laparotomy. DESIGN: Cost analysis study using the hospital administrative database (Canadian Task Force classification II-2). SETTING: University teaching hospital. PATIENTS: Eighty-nine women. Intervention. Tubal anastomosis by laparoscopy (43) and by laparotomy (46). MEASUREMENTS AND MAIN RESULTS: Tubal anastomosis took longer when performed by laparoscopy than by laparotomy; however, the total time patients spent in the operating room was similar. Women treated by laparoscopy spent more time in the recovery room. Labor costs for nurses in the operating room and recovery room costs were significantly higher in the laparoscopy group. Costs for operating room supplies were similar. Pharmacy costs and expenses in the ward were lower in the laparoscopy group. The mean total cost for laparoscopic tubal anastomosis was $861 +/- 137 and for laparotomy was $1348 +/- 188 (p <0.001). CONCLUSION: Laparoscopic tubal anastomosis costs less than tubal anastomosis by laparotomy.     

子宫内膜异位症合并不孕症的治疗策略

子宫内膜异位症（EMs）是妇科的常见病。单纯激素治疗并不能改善EMs合并不孕患者的生育结局。腹腔镜切除/剥除Ⅰ、Ⅱ期EMs病灶可增加不孕妇女的活产率。对于Ⅲ～Ⅳ期EMs合并不孕的首选治疗多数认为应采用手术+促性腺激素释放激素激动剂（GnRHa）,但也有一些异议。目前还没有证据表明哪一种腹腔镜下的手术技术可以获得更好的效果。荟萃分析发现EMs合并不孕患者与输卵管因素患者比较,助孕的总妊娠率下降约37%。有研究提示体外受精-胚胎移植（IVF-ET）前延长应用GnRHa可能会提高IVF的持续妊娠率和种植率。部分研究者认为,手术剥除卵巢内异囊肿会明显降低卵巢功能,而另一些作者则认为只要积累经验,注意保护卵巢组织,则手术对卵巢功能的影响不大。Ⅰ～Ⅱ期EMs术后可给予一定时间试孕,而Ⅲ～Ⅳ期EMs术后则应积极考虑助孕。对于助孕前是否应先行腹腔镜手术处理卵巢内异囊肿,目前存在争论。EMs复发,用药后助孕,特别是2次或以上的IVF,妊娠率明显优于再次手术。鉴于EMs对妊娠许多环节都有不利影响,助孕前先用药抑制EMs的活动无疑有利于助孕结果。     

Role of laparoscopy in the treatment of endometriosis-associated infertility

Endometriosis is assumed to be one of the causative factors of infertility, although the mechanism remains to be elucidated. Mechanical factors distorting the pelvic anatomy and/or changes in the biochemical and cellular environment in the peritoneal cavity are possible contributing factors impairing fertility. Laparoscopy is a widely used diagnostic and therapeutic means of treating endometriosis-associated infertility. However, pregnancy outcome after laparoscopy varies depending on preexisting tubal adhesions and endometriosis. Without tubal adhesions, the pregnancy rate is essentially the same irrespective of the presence or stages of endoemetriosis. Minimal/mild endometriosis benefited the most from laparoscopic manipulation when tubal adhesions were present. On the other hand, IVF-ET outcome of patients who previously underwent laparoscopy was not influenced by preexisiting tubal adhesions and endometriosis.     

Neosalpingostomy: comparison of 24- and 72-month follow-up time shows increased pregnancy rate

Seventy-two patients, 54 for 5 years and 18 for 6 years, were evaluated between 1 and 2 years and 5 and 6 years after bilateral neosalpingostomy. A 27.7% intrauterine pregnancy rate was reported in those patients treated between 1976 and 1978, with a 14% ectopic pregnancy rate. The subsequent 5- to 6-year follow-up study revealed an increase in the pregnancy rate to 41.6% and in the ectopic pregnancy rate to 17.1%. The increase in the pregnancy rate may reflect the ability of the fallopian tube for ciliogenesis and intrinsic repair. Thus if patients have not conceived within 2 years of neosalpingostomy for distal tubal obstruction, significant reproductive potential still exists.     

ICSI pregnancy outcomes following hysteroscopic placement of Essure devices for hydrosalpinx in laparoscopic contraindicated patients

This study investigated the use of hysteroscopic Essure device placement for the treatment of hydrosalpinx-related infertility in patients with laparoscopic contraindications and compared their pregnancy outcomes following assisted conception treatment with those of patients having had laparoscopic tubal ligation. A total of 102 infertile patients were diagnosed with unilateral or bilateral hydrosalpinges: 26 patients had laparoscopic contraindications and were treated hysterscopically and 76 patients were treated laparoscopically. In total, 66 intracytoplasmic sperm injection (ICSI) and 39 frozen embryo transfer (FET) procedures were performed. In the hysteroscopy group, 13 ICSI and eight FET in 16 patients resulted in 10 pregnancies (pregnancy rates 47.6% per transfer and 62.5% per patient), and in the laparoscopy group, 53 ICSI and 31 FET embryo transfers in 54 patients resulted in 36 pregnancies (pregnancy rates 42.9% per transfer and 66.7% per patient). Live birth rates per assisted reproduction procedure were 23.8% (5/21) in the hysteroscopy group and 32.1% (27/84) for the laparoscopy group. The hysteroscopic placement of Essure devices to isolate hydrosalpinx prior to assisted conception treatment produced pregnancy outcomes comparable to those produced following laparoscopic tubal ligation. The live birth rates indicate that a larger, more comparative, prospectively randomized study is required.Infertile patients with tubal disease require surgical treatment before they can continue with fertility treatment. There are two main surgical methods that can be used, hysteroscopic and laparoscopic, the latter being the standard surgical method. However, some patients have disease that makes the use of laparoscopy inappropriate. For these patients the placement of Essure® devices by hysteroscopic surgery maybe the most suitable treatment method. One hundred and two patients were diagnosed with unilateral or bilateral hydrosalpinges – tubal disease. Twenty six patients had to have hysterscopic surgery and 76 patients had laparoscopic surgery. After their tubal surgery some patients continued to have fertility treatment, 66 ICSI and 39 frozen embryo transfers (FET) were performed. Thirteen ICSI and 8 FET embryo transfers in 16 patients from the hysteroscopy group resulted in 10 pregnancies, a 47.6% per transfer and 62.5% per patient pregnancy rate. Fifty three ICSI and 31 FET embryo transfers in 54 patients from the laparoscopic group resulted in 36 pregnancies, a 42.9% per transfer and 66.7% per patient rate. Live birth rates per ART procedure were 23.8% (5/21) in the hysteroscopic group compared with 32.1% (27/84) for the laparoscopic group. The hysteroscopic placement of Essure® devices for tubal disease prior to fertility treatments resulted in pregnancy outcomes that were comparable to the outcomes obtained following laparoscopic surgery.     

Salpingoscopy: systematic use in diagnostic laparoscopy.

OBJECTIVE: To evaluate the importance of salpingoscopy together with laparoscopy in the diagnosis of tubal pathology. DESIGN: Salpingoscopy was performed as a complementary method in patients who were subjected to diagnostic laparoscopy. The relationship between the salpingoscopy and (1) the patient's previous history of tubal disease and (2) laparoscopic diagnoses was evaluated. SETTING: Private patients referred to the Instituto de Fertilidad, Buenos Aires. PATIENTS, PARTICIPANTS: Forty-two patients undergoing a diagnostic laparoscopy during the evaluation of their fertility or as a follow-up of previous therapy. MAIN OUTCOME MEASURE(s): Salpingoscopy was performed, using a colpomicrohysteroscope. We evaluated alterations in major and minor folds and their vascularization, the presence of microadhesions, and cellular nuclei dyed with methylene blue in the tubal lumen. RESULTS: Fifty percent of the patients who had no previous history of tubal disease presented with endosalpingeal alterations, and in 37% of the normal laparoscopies the salpinx had unilateral or bilateral salpingoscopic abnormalities. CONCLUSIONS: Salpingoscopy is a useful method to evaluate oviducts, before assuming their normality, and consideration of these women for assisted reproductive technology.     

Laparoscopic microsurgical tubal anastomosis

The authors explored the feasibility of performing true microsurgery through the laparoscope in 1990. The first laparoscopic microsurgical tubal anastomosis was performed in February 1992. Operative laparoscopy will continue to expand as technical feasibility continues to improve, driven by both hardware advances and increased surgical dexterity. Laparoscopic microsurgery will introduce a new dimension to reproductive surgery and over time, will replace laparotomy for microsurgery.     

Fertility outcome after tubal anastomosis by laparoscopy and laparotomy

STUDY OBJECTIVE: To evaluate fertility outcome and benefit of laparoscopic tubal anastomosis compared with laparotomy. DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: University hospital. PATIENTS: Eighty-one women requesting reversal of sterilization. Fertility outcome was analyzed in 76 patients for a minimum of 6 months. INTERVENTION: Laparoscopic tubal anastomosis in 37 women and abdominal tubal anastomosis in 44. MEASUREMENTS AND MAIN RESULTS: In both groups anastomosis was performed in two layers with four stitches using microsurgical technique. Overall pregnancy rates were 80.5% in the laparoscopy and 80.0% in the laparotomy group. The mean interval from operation to pregnancy was similar in the two groups (p = 0.9). Mean operating time was significantly longer for laparoscopy (201.9 +/- 33.8 min) than for laparotomy (148.7 +/- 32.5 min), including diagnostic laparoscopy. However, mean hospital stay was shorter for laparoscopy than for laparotomy (3.3 +/- 2.0 vs 6.1 +/- 0.6 days, p <0.05). CONCLUSION: Laparoscopic tubal anastomosis is less invasive and could be an alternative to laparotomy for reversal of tubal sterilization. Advanced laparoscopic equipment and much experience could enhance the pregnancy rate and reduce operating time.     

女性生殖器结核对体外受精-胚胎移植妊娠结局的影响

目的:探讨女性生殖器结核(FGTB)对体外受精-胚胎移植(IVF-ET)妊娠结局的影响。方法:选择2006年1月至2009年12月于河北医科大学第四医院生殖医学科行IVF-ET助孕的双侧输卵管梗阻患者,其中结核性输卵管梗阻(结核组)66例,非结核性输卵管梗阻(非结核组)240例,比较两组促性腺激素(Gn)用量、获卵数、受精率、优质胚胎率、种植率、临床妊娠率、流产率和分娩率的差异。结果:两组Gn用量、获卵数、受精率、优质胚胎率比较,差异无统计学意义(P>0.05)。结核组种植率、临床妊娠率、分娩率显著低于非结核组(P<0.05),流产率显著高于非结核组(P<0.05)。结论:结核性输卵管梗阻患者IVF-ET临床妊娠率降低,流产率增高,应重视女性生殖器结核对IVF-ET妊娠结局的影响。     

Bilateral Ovarian Pregnancy After in Vitro Fertilization and Embryo Transfer in a Patient with Tubal Factor Infertility

Primary ovarian pregnancy is very rare event after natural pregnancy or assisted reproductive technology (ART) procedures. Although there are a few reports about unilateral ovarian pregnancy after in vitro fertilization and embryo transfer (IVF-ET), there has been no report about bilateral ovarian pregnancy. Moreover, it is difficult to diagnose an ovarian pregnancy following in vitro fertilization and embryo transfer because of enlarged ovary, fluid collection in pelvic cavity, and its low incidence. We present a case of a patient who underwent IVF-ET due to tubal factor infertility, but the patient developed bilateral ovarian pregnancy and was performed both ovarian wedge resection through laparotomy.     

Should laparoscopy be a mandatory component of the infertility evaluation in infertile women with normal hysterosalpingogram or suspected unilateral distal tubal pathology?

OBJECTIVE: To assess the diagnostic benefit of laparoscopy in infertile women with normal hysterosalpingography (HSG) or suspected unilateral pathology on HSG. STUDY DESIGN: Charts of infertile women that underwent complete infertility evaluation between 1996 and 1998 were retrospectively reviewed. Eighty-six patients in whom both HSG and laparoscopy were performed were included in the study. HSG results were compared with laparoscopic findings and the suggested treatment based on HSG results was compared with the treatment plan based on laparoscopic findings. RESULTS: Among 63 patients with a normal HSG or suspected unilateral tubal pathology, who were assigned to ovulation induction and intrauterine insemination (IUI), 60 patients were found to have laparoscopic findings that did not necessitate any change in the original treatment plan. In three patients (4.8%), abnormalities discovered at laparoscopy were of such an extent that a change in the original treatment regimen and referral to in vitro fertilization (IVF) was needed. Among 23 patients with suspected bilateral tubal occlusion on HSG, 16 patients (69.6%) were found to have an abnormal laparoscopy with bilateral tubal adhesions, 6 patients (26%) had unilateral tubal adhesions, and 1 patient (4.3%) had pelvic adhesions with no obstruction. These latter findings led to changes in the original treatment plan of these seven patients from IVF to ovulation induction and IUI. CONCLUSIONS: Laparoscopy may be omitted in women with normal HSG or suspected unilateral distal tubal pathology on HSG, since it was not shown to change the original treatment plan indicated by HSG in 95% of the patients. However, laparoscopy should be recommended in cases with suspected bilateral tubal occlusion on HSG, since it altered the original treatment plan in 30% of the patients from IVF to induction of ovulation with IUI. The reassuring results found in the present study may be related to the low prevalence of pelvic inflammatory diseases and endometriosis in our population.     

Tubal surgery vs in vitro fertilization for the treatment of infertility due to distal tubal occlusion

Background: The optimal treatment of infertility due to tubal occlusion has not been established. Many practitioners feel that the success of tubal repair exceeds that of in vitro fertilization (IVF); however, previous studies of pregnancy after tubal surgery have been limited by bias in patient selection, follow-up, or surgical expertise. The purpose of the present study was to determine the outcome after repair of distal tubal occlusion performed by experienced surgeons in an unselected patient population with consistent follow-up.Design: Chart review with telephone contact of patients lost to follow-up.Methods: The records of all tubal surgery performed between 1989 and 1996 at the University of Alabama Hospital and The Kirklin Clinic outpatient surgery facility were reviewed. All women with infertility due to distal tubal occlusion, with or without pelvic adhesions, who had no other significant infertility factors were included for study. Details of the infertility history, operative procedure, and postoperative course were recorded. Patients lost to follow-up within 1 year after surgery were contacted by telephone for information regarding subsequent testing and treatment and pregnancy outcome.Results: Eighty-three women aged 19–39 years met the entry criteria for this study. Follow-up of at least 1 year was obtained in all but 11 patients. Tubal surgery was accomplished by laparotomy in 19 women; 64 women underwent tubal repair by laparoscopy. Within 1 year of surgery, 9 hysterosalpingograms, 51 clomiphene cycles, and 20 gonadotropin cycles were performed on the study group. Pregnancy was achieved within 1 year in 13 women; of these, there were 6 live births (9.6% birth rate per surgery), 2 spontaneous abortions, and 3 ectopic pregnancies. There were no live births among women who underwent tubal repair by laparotomy. None of the postoperative gonadotropin cycles resulted in pregnancy. Seven women underwent IVF within 1 year after surgery because of extensive tubal damage noted at surgery. Based on current charges for the infertility treatments performed, the cost of a live birth with tubal surgery exceeded $120,000, versus less than $50,000 per live birth with IVF using results obtained nationally or at UAB.Conclusions: The cost-effectiveness of reconstructive surgery in unselected patients with distal tubal occlusion is less than that of IVF. Empiric use of gonadotropins for ovarian stimulation does not improve pregnancy rates after tubal surgery. In our series, laparoscopic tubal repair seemed to give results superior to that of laparotomy.     

Ovarian Response to Gonadotropins in Patients With Tubal Factor Infertility: Salpingectomy Versus Nonsalpingectomy

Study ObjectiveTo evaluate the effects of salpingectomy on the ovarian response to gonadotropins and in vitro fertilization–embryo transfer (IVF-ET) cycle outcomes in women with tubal factor infertility.DesignA retrospective study (Canadian Task Force Classification II-3)SettingAn in vitro fertilization laboratory in a university hospital in Taiwan.PatientsWe analyzed the outcomes of 288 consecutive fresh IVF-ET cycles in 251 consecutive women with tubal factor infertility from January 2001 to December 2011. Two hundred eighty-eight cycles were divided into 2 groups comprising 103 cycles with laparoscopic salpingectomy and 185 cycles with prior bilateral tubal sterilization, laparoscopic tuboplasty, or proximal tubal occlusion as the control group.InterventionsControlled ovarian hyperstimulation and IVF-ET.Measurements and Main ResultsThe main outcome was measured by comparing the duration of stimulation, number of gonadotropin ampoules per cycle, number of follicles, number of oocytes retrieved, fertilization rate, implantation rate, clinical pregnancy rate, and live birth rate. We observed no significant difference in any ovarian response parameter between the salpingectomy and nonsalpingectomy groups. Implantation rates, clinical pregnancy rates, and live birth rates were similar. The mean numbers of follicles and oocytes retrieved ipsilateral to the operated side in the salpingectomy group were similar to the numbers of follicles and oocytes retrieved from the nonoperated ovary.ConclusionsLaparoscopic salpingectomy did not have a negative effect on the ovarian response in women with tubal factor infertility.     

Negative laparoscopy is highly predictive of negative second-look laparotomy following chemotherapy for ovarian, tubal, and primary peritoneal carcinoma

OBJECTIVE: To determine the negative predictive value of second-look laparoscopy compared to laparotomy for assessment of pathologic complete response (CR) in patients with epithelial ovarian, tubal, and peritoneal carcinoma who achieved a clinical CR. METHODS: Data were analyzed from patients who participated in two sequential phase II clinical trials following primary cytoreductive surgery. Both trials required surgical evaluation for pathologic CR in those patients who achieved clinical CR. Protocol specified that assessment begin with laparoscopy; if negative, conversion to laparotomy was required. Collection of peritoneal washings was performed laparoscopically. RESULTS: One hundred thirty-six patients entered the 2 sequential clinical trials. Ninety-nine patients achieved clinical CR and 95 underwent second-look surgery (SLO). Seventy patients began SLO with laparoscopy and converted to planned laparotomy after biopsies were negative. Eighteen cases were positive based on laparoscopy with frozen section. Five additional patients had peritoneal washings and/or permanent pathology positive based on laparoscopic findings, yielding a positive SLO rate of 32.9%. Four of the 52 patients who underwent laparotomy (7.7%) were found to have persistent disease that was not detected on laparoscopic biopsy or washings and represent false-negative laparoscopy; all four patients had disease at peritoneal-based sites. The sensitivity and negative predictive value for intraoperative diagnosis of persistent disease by laparoscopy were 66.6% and 82.7%, respectively. The sensitivity and negative predictive value of laparoscopic peritoneal biopsies and washings compared to laparotomy, as determined by final pathology, were 85.2% and 91.5%, respectively. CONCLUSION: A negative second-look laparoscopy with negative peritoneal pathology and cytology is 91.5% predictive of negative laparotomy and is associated with a low complication rate even in the setting of prior extensive cytoreductive surgery. The small increase in sensitivity and negative predictive value afforded by laparotomy does not warrant the increased morbidity.     

Essure® hydrosalpinx occlusion prior to IVF-ET as an alternative to laparoscopic salpingectomy

Objective

To investigate the success rate of proximal tubal occlusion with Essure^® devices in subfertile women with unilateral or bilateral hydrosalpinx and to observe the results of subsequent treatment with IVF-ET and/or frozen embryo transfer.

Study design

Prospective, single-arm, clinical study in 20 women with unilateral or bilateral hydrosalpinges (all visible on transvaginal ultrasound) due to undergo IVF-ET and/or frozen embryo transfer. In all patients, laparoscopy was considered to be contraindicated due to extensive pelvic adhesions.

Result(s)

In all patients the Essure^® devices were placed in an ambulant setting without any complications. Proximal tubal occlusion was confirmed by hysterosalpingography in 19 out of 20 patients (95%) and in 26 of 27 treated tubes (96%). After 45 embryo transfer procedures in 19 patients, 18 pregnancies with 12 live births, 6 miscarriages and 1 immature delivery (probably related to cervical insufficiency leading to chorioamnionitis and subsequent rupture of the membranes) were observed.

Conclusion(s)

Essure^® devices are effective in inducing proximal tubal occlusion in subfertile patients with hydrosalpinges. After artificial reproductive treatments a cumulative live birth rate per patient of 63% and a cumulative live birth rate per transfer of 27% were achieved. The latter was related to the large proportion of patients with severe endometriosis.

Influence of various tubal surgeries to serum antimullerian hormone level and outcome of the subsequent IVF-ET treatment

Abstract

Objective: To compare the influence of various tubal surgeries to ovarian reserve via serum level of antimullerian hormone (AMH) and the subsequent in vitro fertilization and embryo transplantation (IVF-ET) outcome in patients with simple tubal infertility.

Study design: A prospective cohort study was conducted on 134 IVF cycles undegone by 26 and 34 cases with bilateral and unilateral salpingectomy, respectively, 23 cases with bilateral oviducts interrupted in the proximal and 51 cases with bilateral oviducts obstruction without intervention as controls.

Results: Serum AMH displayed its great superiority to traditional markers of ovarian reserve in correspondence with antral follicles count and decisive effect for the number of oocytes retrieved after stimulation in each group. No significant differences on ovarian reserve and responsiveness or IVF-ET outcome existed among four groups comparable on essential characteristics, except for numerically higher clinical pregnancy rate and live birth rate after various tubal surgeries versus no intervention for bilateral oviducts obstruction. Especially, bilateral salpingectomy precursed the statistically highest implantation rate (51.0% versus 28.0%, 39.1%, 30.4%) and numerically best IVF outcome.

Conclusion: Tubal surgical procedures have some beneficial effect for improving IVF outcome without significant impact on ovarian reserve or responsiveness. Bilateral salpingectomy appears to be an appropriate procedure before IVF treatment for bilateral salpingitis, especially hydrosalpinx.
