Uterine rupture after hysteroscopic resection of uterine septum

OBJECTIVE: To describe a patient who underwent hysteroscopic resection of a uterine septum for recurrent miscarriage. The subsequent labor caused uterine rupture. DESIGN: Case report. SETTING: Academic medical center. PATIENT(S): A 37-year-old nullipara with three previous miscarriages. INTERVENTION(S): Resection of the septum by cutting diathermy using the operating hysteroscope. MAIN OUTCOME MEASURE(S): Pregnancy and delivery. RESULT(S): The patient had an uneventful pregnancy and spontaneous labor at 41 weeks. Cesarean section was performed because of suspected fetal distress. During cesarean section, the uterus was ruptured transversely along the fundus at the line of the attachment of the septum. CONCLUSION(S): When fetal distress occurs after previous uterine surgery, uterine rupture must be considered as a possible cause and appropriate treatment is necessary.     

Cervical assessment in women with hysteroscopic uterine septum resection: a retrospective cohort study

Objective: To estimate whether cervical length measured by transvaginal ultrasonography in women with a history of hysteroscopic uterine septum resection predicts spontaneous preterm birth <35 weeks’ gestation.

Methods: This retrospective cohort study compared women who had undergone hysteroscopic metroplasty, and were subsequently pregnant with singleton gestations delivered January 2003 to December 2012, to a low-risk control group. Transvaginal ultrasonographic cervical lengths were measured 16–30 weeks’ gestation. The primary outcome was spontaneous preterm birth <35 weeks’ gestation and the primary exposure variable of interest was cervical length.

Results: Women with a uterine septum resected (N?=?24) had a shorter cervical length (2.90?cm) than the low-risk control group (N?=?141, 4.31?cm, p?p?p?p?p?=?0.003). Women with septum resected were more likely to receive corticosteroids (33.3% versus 11.3%, p?=?0.010), but were not more likely to have a spontaneous preterm birth <35 weeks (4.2% versus 0.7%, p?=?0.27). There were no differences noted in secondary outcomes including neonatal morbidity.

Conclusion: Pregnant women with a history of a hysteroscopic uterine septum resection have shorter cervical lengths than low-risk controls but may not be at a higher risk of spontaneous preterm birth <35 weeks’ gestation. Further research with a larger sample size is needed to evaluate this group of women to determine if transvaginal ultrasonographic cervical length assessment is of benefit.     

Hysteroscopic metroplasty in patients with a uterine septum and otherwise unexplained infertility

Objective

To evaluate the reproductive outcomes of patients with a uterine septum and otherwise unexplained infertility who underwent hysteroscopic metroplasty, and to compare them with those of patients with the same diagnosis who did not have hysteroscopic metroplasty.

Methods

The present retrospective study included 127 patients with diagnosis of a uterine septum and otherwise unexplained infertility. The reproductive outcomes of 102 patients who underwent hysteroscopic metroplasty (group 1) and 25 patients who rejected the operation (group 2) were compared.

Results

Of the 102 patients who underwent hysteroscopic metroplasty, 44 (43.1%) were able to achieve pregnancy, as compared with 5 (20%) of the 25 patients who did not undergo the operation (P = 0.03). The abortion rate was 11.4% (5/44) in group 1, compared with 60% (3/5) in group 2 (P = 0.02). The live birth rate was 35.3% (36/102) in group 1, as compared with 8% (2/25) in group 2 (P = 0.008).

Conclusions

The results indicate that hysteroscopic metroplasty improves reproductive outcome for patients with a uterine septum and otherwise unexplained infertility.     

Hysteroscopic treatment of the uterine septum: A clinician’s experience

Objective: I reviewed my experience with the diagnosis and hysteroscopic treatment of uterine septa. Study Design: This article is a retrospective review of cases from 1992-1999. A septate uterus was diagnosed in a total of 40 patients, and all were treated by hysteroscopic resection. Results: The rate of preoperative pregnancy loss was 77.4%, and the uncomplicated delivery rate was 6.5%. After hysteroscopic septum resection 21 patients reported a total of 22 pregnancies with an 18.2% miscarriage rate and a 77.3% uncomplicated delivery rate. Conclusion: Hysteroscopic treatment of uterine septa is a safe, simple, and effective procedure. It can be used for all types of uterine septa, it attains optimal obstetric outcomes, and it should be undertaken whenever a uterine septum is diagnosed. (Am J Obstet Gynecol 2000;182:1414-20.)     

Retrospective cohort study of the risk factors for secondary infertility following hysteroscopic metroplasty of the uterine septum in women with recurrent pregnancy loss

Purpose

A hysteroscopic metroplasty was performed for women with recurrent pregnancy loss owing to a uterine septum, following which some women became infertile. The aim of this study was to elucidate the risk factors of secondary infertility 1 year after hysteroscopic metroplasty for a uterine septum.

Methods

A retrospective, single‐center, cohort study included women with a history of at least two miscarriages that had been attributed to a uterine septum who underwent a hysteroscopic metroplasty. The patients’ background data were compared between the patients who conceived and those who remained infertile at 1 year postoperatively. The data were analyzed by using the Mann–Whitney U‐test and multivariate analyses.

Results

The postoperative live birth rate was 83.9% (n = 26), with persistent infertility in five women at 1 year. When comparing the pregnancy group with the infertile group, the women in the postoperative infertility group were significantly older than those in the postoperative pregnancy group. The multivariate analysis showed that age was an independent risk factor for persistent infertility.

Conclusion

Age was identified as an independent risk factor for postoperative secondary infertility. Therefore, surgery as early as possible is recommended.     

Intrauterine adhesion prevention with Malecot catheter after hysteroscopic myomectomy: A novel approach

ObjectiveIntrauterine adhesion after hysteroscopic myomectomy contributes to infertility, recurrent miscarriages, menstrual irregularities, and hinders pregnancy outcomes. The aim of this study was to apply the indwelling Malecot catheter in prevention of intrauterine adhesion after hysteroscopic myomectomy and to further evaluate the effectiveness of this approach with reported live birth rates in infertile patients who underwent subsequent infertility treatment.Materials and methodsSeventeen patients with FIGO Classification System PALM-COIEN Type 0 or 1 submucous myoma that received hysteroscopic myomectomy were recruited in this retrospective analysis. Post-operative insertion of the Malecot catheter via the aid of the uterine sound was performed and the catheter was left in place for seven days.ResultsThe mean duration of TTP (time to pregnancy) was 15.6 months after hysteroscopy. Within three years after the operation, 10 out of 17 infertility patients achieved ongoing pregnancy over 12 weeks. Ongoing pregnancy rate was 58.8% (10/17). Eight patients achieved live birth (seven singletons, one twin pregnancy) with mean gestational age of 38 weeks. Live birth rate was 47.1% (8/17).ConclusionThe Malecot catheter is an inexpensive, easy-to-operate, and effective physical barrier method for preventing IUA in infertile patients undergoing hysteroscopic myomectomy with high live birth rate and no obvious visible post-operative adhesions.     

宫腔镜子宫中隔切除术后辅助治疗对妊娠结局的影响

目的：探讨宫腔镜子宫中隔切除术(TCRS)后辅助治疗对妊娠结局的影响。方法：收集2007年1月至2008年12月首都医科大学附属复兴医院行TCRS 的患者共216例,随访到195例。术后患者分为无辅助治疗组(60例,术后无辅助治疗)、人工周期组(33例,术后予人工周期3个月)、人工周期+宫内节育器(IUD)组(102例,术后予人工周期3个月同时放置IUD 3个月)。随访20～44个月,随访内容为3组患者的自然流产、早产、胎死宫内和足月分娩情况。结果：3组术后自然流产率、早产率、胎死宫内率和足月分娩率分别为无辅助治疗组28.57%、2.86%、2.86%和60.00%;人工周期组14.29%、5.71%、0和65.71%;人工周期+IUD组27.27%、6.49%、0和48.05%。3组差异无统计学意义(P>0.05)。结论：TCRS术后传统的辅助治疗(人工周期;人工周期+IUD)与无辅助治疗相比,在改善妊娠结局方面差异不大。     

Reproductive outcome following resectoscope metroplasty in women having a complete uterine septum with double cervix and vagina

Objective

To evaluate reproductive outcomes in women with complete uterine septum with double cervix and vagina following resectoscope metroplasty.

Methods

The pregnancy outcomes of 21 women who underwent vaginal and uterine septum resection were compared with those of 15 untreated women with similar clinical characteristics. The Fisher exact test and the Mann-Whitney test were used for statistical analysis.

Results

Cycle fecundity was better (33.4% ± 28.5% vs 12.2% ± 4.7%; P = 0.046), the rate of term delivery significantly increased (P < 0.05), and the rate of spontaneous abortion decreased (P < 0.05) in the treatment group.

Conclusion

Resectoscope metroplasty was found to improve the pregnancy outcomes of women having primary infertility or a history of pregnancy loss associated with a complete uterine septum with double cervix and vagina.     

The outcome of singleton pregnancies after IVF/ICSI in women before and after hysteroscopic resection of a uterine septum compared to normal controls

Objective(s)

To evaluate the effect of hysteroscopic resection of a large uterine septum (Class V according to the American Fertility Society (AFS) classification) and of a small partial uterine septum (Class VI according to AFS classification or arcuate uterus) on the abortion rate in pregnancies after IVF and ICSI.

Study design

The retrospective matched control study included 31 women who conceived following IVF or ICSI before hysteroscopic resection of a large (12 women) or small partial (19 women) uterine septum and 106 women who conceived following IVF or ICSI after hysteroscopic resection of a large (49 women) or small partial (57 women) uterine septum. For each pregnancy in the study group, we found two consecutive pregnant control women from the IVF/ICSI registry who had a normal uterus and were matched for age, BMI, stimulation protocol and the use of IVF or ICSI and for various infertility causes. The abortion/pregnancy rate was the main outcome measure. Data on the septum length were obtained during hysteroscopic resection by comparing the length of the 1.4 cm long yellow tip of the electric knife to the length of the resected septum.

Results

The abortion rate before hysteroscopic metroplasty was significantly higher, both in women with a small partial septum (78.9% before resection vs. 23.7% in the normal controls, OR 12.08) and a large septum (83.3% before resection vs. 16.7% in normal controls, OR 25.00) compared to women with a normal uterus. After the surgery, the abortion rate was comparable to the abortion rate in women with normal uterus: in both women with a small partial and women with a larger septum.

Conclusion(s)

Similar to a large uterine septum, a small partial uterine septum is an important and hysteroscopically preventable risk factor for spontaneous abortion in pregnancies after IVF and ICSI.

Determinants of fertility and reproductive success after hysteroscopic septoplasty for women with unexplained primary infertility: a prospective analysis of 88 cases

Objective

To evaluate prospectively the effect of hysteroscopic septoplasty as therapy for unexplained primary infertility in women with uterine septum as a sole cause for reproductive failure and to define the factors influencing reproductive success.

Study design

In a prospective comparative study, we enrolled 103 infertile women with uterine septum as a sole cause for reproductive failure. They had had unexplained primary infertility >2 years and a follow-up >12 months. Uterine anomalies were diagnosed by means of hysterosalpingography (HSG) and 2D-transvaginal sonography (TVS) with intrauterine saline infusion. Hysteroscopic septoplasty was performed in the early follicular phase. Pregnancy rates (PR) according to patient and septum characteristics (septum size) were the main outcome measures.

Results

Follow-up was complete for 88 patients. The mean (±SD) age of the patients was 36.1 ± 2.1 years. Forty-two patients became pregnant (40.7%). The mean (±SD) delay in conception was 7.5 ± 2.6 months. Nearly 80% of the pregnant women conceived spontaneously. Of 44 pregnancies in 42 women, 36 live newborns were delivered. The PR was significantly higher in women <35 years of age or with <3 years of unexplained primary infertility. Moreover, in women with a septum size larger than one-half of their uterine length the PR was significantly higher than those with septum size <1/2 of their uterus (P = .12).

Conclusion

Fertility and pregnancy after hysteroscopic septoplasty in women with unexplained primary infertility and uterine septum as a sole cause for reproductive failure seems to depend on patient age, duration of infertility before septoplasty, and septum size. Women with a septum size larger than one-half of their uterine length have a higher chance of successful pregnancy after hysteroscopic septoplasty.

A comparison of intrauterine balloon,intrauterine contraceptive device and hyaluronic acid gel in the prevention of adhesion reformation following hysteroscopic surgery for Asherman syndrome: a cohort study

Objective

To compare the efficacy of intrauterine balloon, intrauterine contraceptive device and hyaluronic acid gel in the prevention of the adhesion reformation after hysteroscopic adhesiolysis for Asherman's syndrome.

Study design

Retrospective cohort study of 107 women with Asherman's syndrome who were treated with hysteroscopic division of intrauterine adhesions. After hysteroscopic adhesiolysis, 20 patients had intrauterine balloon inserted, 28 patients had intrauterine contraceptive device (IUD) fitted, 18 patients had hyaluronic acid gel instilled into the uterine cavity, and 41 control subjects did not have any of the three additional treatment measures. A second-look hysteroscopy was performed in all cases, and the effect of hysteroscopic adhesiolysis was scored by the American Fertility Society classification system.

Results

Both the intrauterine balloon group and the IUD group achieved significantly (P < 0.001) greater reduction in the adhesion score than that of the hyaluronic acid gel group and control group. The efficacy of the balloon was greater than that of the IUD (P < 0.001). There was no significant difference in results between the hyaluronic acid gel group and the control groups.

Conclusion

The insertion of an intrauterine balloon or intrauterine device is more effective than the use of hyaluronic acid gel in the prevention of intra-uterine adhesion reformation.     

Comparative outcomes of hysteroscopic examinations performed after uterine artery embolization or laparoscopic uterine artery occlusion to treat leiomyomas

Hysteroscopic examination of the uterine cavity revealed that patients previously treated for intramural myoma(s) by uterine artery embolization had a significantly higher incidence of abnormal findings compared with patients treated by laparoscopic occlusion of uterine arteries (59.5% vs. 2.7%). In particular, there was a higher incidence of necrosis in the uterine cavity of patients subjected to uterine artery embolization (43.2%) compared with patients after surgical uterine artery occlusion (2.7%).     

The diagnosis and reproductive outcome after surgical treatment of the complete septate uterus, duplicated cervix and vaginal septum

OBJECTIVE: This study was undertaken to evaluate the diagnostic management and the reproductive outcome after surgical repair of a rare reproductive malformation. STUDY DESIGN: Sixteen women with a complete septate uterus, double cervix, and a longitudinal vaginal septum were referred for evaluation. Presenting complaints were chiefly pregnancy loss in parous women (n=9) and dyspareunia in nulligravid women (n=7). The combination of hysterosalpingography, ultrasonography, and/or magnetic resonance imaging was used to correctly identify the anomaly in 15 of the 16 cases. Both hysteroscopic (n=11) and transabdominal (n=5) surgical techniques were used to repair the uterine septum. RESULTS: In no case was the correct diagnosis made before referral; the uterus didelphys was the most common misdiagnosis. The preoperative pregnancy loss was 81%. Postoperatively, 12 women conceived for a total of 17 pregnancies; there were 14 term live births or ongoing pregnancies in the third trimester (82%), with a first trimester spontaneous abortion rate of 18%. In 9 women who conceived after hysteroscopic surgery, term live births occurred in 9 of 12 (75%) conceptions. A modified Tompkins metroplasty was performed in 5 women with subsequent term live births or ongoing third trimester pregnancies in 5 of 5 (100%) patients. CONCLUSION: The identification of a duplicated cervix and a vaginal septum is consistent with several uterine malformations, which leads to frequent misdiagnosis and errors in management. Significant pregnancy wastage, obstetric complications, and dyspareunia are common, and surgical treatment is therefore advisable. Making the best choice between hysteroscopic or transabdominal metroplasty depends on the anatomic features of the cervix and the uterine cavity, but optimal patient management requires familiarity with both techniques.     

子宫中隔及宫腔镜子宫中隔切除术对妊娠及其结局的影响

目的 探讨子宫中隔影响妊娠的机理及官腔镜子宫中隔切除术（TCRS）的生殖预后。方法 对111例由于子宫中隔所致不孕或反复流产患者行TCRS,根据孕产史分为不孕组34例、不育组77例。随访TCRS的治疗效果,并与同期1548例正常结构子宫妊娠妇女（对照组）的妊娠经过和结局进行比较。同时对30例（不孕组8例,不育组22例）切除的中隔组织和子宫肌层进行了组织学超微结构观察,用真色彩病理图像分析系统对平滑肌纤维、胶原纤维含量和雌、孕激素受体阳性表达水平进行定量分析。结果 （1）不孕组7例、不育组13例子宫中隔内膜腺体数目少于子宫内膜或与子宫内膜增殖不同步。中隔内膜雌、孕激素受体阳性表达水平低于子宫内膜;中隔基底部和中部平滑肌面密度高于子宫肌层（P〈0．05）,胶原纤维面密度低于子宫肌层（P〈0．05）;中隔尖部和中部小动脉分布少于子宫肌层（P〈0．05）。不孕组患者中隔内膜腺上皮细胞排列紊乱、纤毛稀疏断离,无顶浆分泌。（2）TCRS后不孕组患者妊娠16例次（47．1％,16／34）,明显高于术前（8．8％,3／34）,TCRS前后比较,差异有统计学意义（P〈0．01）;不育组的自然流产率由84．1％（180／214）下降为29．0％（18／62）,TCRS前后比较,差异也有统计学意义（P〈0．01）;足月儿及活婴率分别由3．3％（7／214）、0．9％（2／214）上升至56．4％（35／62）、64．5％（40／62）,TCRS前后比较,差异也有统计学意义（P〈0．01）。（3）TCRS后妊娠者,孕期并发症发生率及围产儿死亡率与对照组比较,差异无统计学意义（P〉0．05）,但TCRS后妊娠者剖宫产率显著高于对照组,差异有统计学意义（P〈0．01）。结论 中隔组织与子宫肌层的组织形态和超微结构异常,是导致流产或不孕的原因,TCRS可明显改善不孕、不育患者的生殖预后,不增加孕期并发症,不影响胎儿发育。
