Laparoscopic salpingostomy for two types of hydrosalpinx: a step-by-step video tutorial.

OBJECTIVE: This study aims to illustrate our laparoscopic salpingostomy approach for two types of hydrosalpinx, emphasizing various reproductive surgical techniques. DESIGN: A step-by-step demonstration of the technique is provided alongside narrated video footage. SETTING: University hospital. PATIENT(S): Infertile patients with hydrosalpinx seeking natural conception. INTERVENTION(S): Laparoscopic salpingostomy for clubbed hydrosalpinx is demonstrated with video and includes the following steps: 1) creating an opening into the tube at the terminal end for hydrosalpingeal fluid drainage; 2) dissecting and removing peritubal and periovarian adhesions; 3) excising redundant fimbrial tissues to restore fimbrial mobility; 4) evert the mucosa using an intussusception method until endothelial folds are visible; 5) confirming tubal patency with a dye test; 6) heating the serosal surface of the tube to evert the edges; 7) suturing the edges using 6-0 vicryl to the proximal serosa of the tube circumferentially with an inverting suture technique; 8) thoroughly irrigating with Ringer's solution to remove blood clots and debris; and 9) applying auto-crosslinked hyaluronan gel to the exposed raw surface. Salpingostomy for the cystic type differs, notably in carefully shaving the adhesive tubal end from the ovary until the tubo-ovarian ligament is completely exposed. MAIN OUTCOME MEASURE(S): The primary aim of salpingostomy is to reduce the likelihood of distal tube re-obstruction. If hydrosalpinx recurs after salpingostomy, there remains a possibility of requiring additional surgery, such as salpingectomy, prior to IVF. RESULT: (s): Extensive adhesions were meticulously dissected and removed from the peritoneal cavity. Fimbrial mobility was restored to establish a patent fallopian tube capable of ovum pickup. Electrocoagulation and suturing techniques were employed to evert the tube edges, effectively reducing the risk of re-obstruction. The utilization of an inverting suture technique aided in inwardly turning the cut edges, minimizing the risk of adhesion formation. CONCLUSION(S): Laparoscopic salpingostomy, when performed by surgeons proficient in reproductive surgical techniques, provides a significant option for patients with hydrosalpinx seeking natural conception. The decision to preform salpingostomy or salpingectomy is usually made intraoperatively on the basis of the severity of tubal disease. Clinical history is also an important factor in decision to perform salpingostomy.

Torsion of distal right hydrosalpinx in a primiparous woman at term: A case report.

INTRODUCTION AND IMPORTANCE: Adnexal torsion is a significant cause of acute pelvic pain and a common gynaecological emergency. While ovarian cysts are well-recognized predisposing factors, hydrosalpinx is a less common precursor. This case report presents a unique instance of isolated fallopian tube torsion accompanied by hydrosalpinx. CASE PRESENTATION: A 27-year-old primiparous woman at 37 weeks gestation presented with severe right lumbar pain. The patient's vital signs were stable, and abdominal and vaginal examinations were conducted. Imaging confirmed a progressing pregnancy and a 7.5 cm hemorrhagic cystic formation on the right side. Suspecting adnexal torsion, she underwent an urgent cesarean section and surgical exploration, which revealed a twisted distal right hydrosalpinx-the treatment involved detorsion, right salpingectomy, and ovarian suspension. Postoperative recovery was uneventful with histopathological confirmation of hydrosalpinx. DISCUSSION: Isolated fallopian tube torsion is rare, particularly during pregnancy. This condition's etiopathogenesis involves rotation of the tube around its ligamentous supports, possibly exacerbated by factors such as hydrosalpinx, pregnancy, and anatomical variances. Despite the availability of imaging techniques, diagnosis remains challenging, often confirmed only during surgical intervention. The literature highlights the importance of considering this diagnosis in pregnant women with acute pelvic pain and identifying characteristic ultrasound features. CONCLUSIONS: Isolated tubal torsion in pregnancy is an exceptional clinical challenge. Early and accurate diagnosis is critical to prevent irreversible damage to the fallopian tube and preserve fertility. This case underscores the need for awareness among clinicians and provides insights into the effective management of such cases.

Hysteroscopic tubal electrocoagulation versus laparoscopic tubal disconnection for the management of hydrosalpinx and subsequent pregnancy outcomes: A randomized clinical trial.

Objective: Hydrosalpinx impairs the success of in vitro fertilization (IVF) embryo transfer. Various surgical approaches, such as fluid aspiration or isolation of the affected fallopian tubes, have been used to enhance the outcome. This study was conducted to evaluate and compare the efficacy of laparoscopic tubal disconnection (LTD) and hydroscopic tubal electrocoagulation (HTE) for hydrosalpinx before IVF. Materials and Methods: After obtaining ethical committee approval, we assessed 112 women who were subfertile due to hydrosalpinx to check their adherence to our selection criteria. Eligible patients were allocated into two groups (LTD vs. HTE). Both groups underwent extensive assessment before the operative procedure. IVF and subsequent embryo transfers were performed in both groups. Live birth and pregnancy rates were evaluated. Results: Patients who underwent LTD prior to IVF embryo transfer had significantly higher live birth (41%), clinical pregnancy (57%), and chemical pregnancy (61%) rates in the LTD group than in the HTE group (12%, 35%, 41%, respectively). However, we could not find a significant difference between the two groups regarding the miscarriage (17% vs. 28%, p=0.33) and multiple pregnancy (14% vs. 12%, p=0.79) rates. No major complications with HTE were observed, except for a case of uterine perforation, whereas two cases of surgical complications occurred in the LTD group. Additionally, we found a significantly shorter operative time and hospital stay (0.5±0.7 days, p=0.012) in the HTE group. Conclusion: LTD may be a more effective approach compared with hysteroscopic tubal electrocoagulation for improving birth and pregnancy rates in patients with IVF and hydrosalpinx.

Four cases of isolated fallopian tube torsion successfully treated with laparoscopic surgery:A case series.

We report four cases of isolated fallopian tube torsion (IFTT) successfully treated with laparoscopic surgery over the past 10 years. Two young women (each 19 years old) were IFTT with paraovarian cyst (POC) and tubal preservation was possible with detorsion and cystectomy. The other two patients (a 41-year-old woman with hydrosalpinx and a 50-year-old woman with hematosalpinx) underwent salpingectomy and adnexectomy, respectively, because there was no desire for tubal preservation. One patient had emergency surgery due to severe abdominal pain, one had semi-emergency surgery due to mild abdominal pain, and the other two were diagnosed during scheduled surgery without symptoms.Although IFTT was considered a very rare disease, our case series and recent reports suggest that it may have been underestimated, as it accounts for approximately 10% of adnexal torsion cases. Preoperative diagnosis of IFTT may be more difficult than for adnexal torsion because of its infrequency and nonspecific, vague clinical symptoms.　Since the prevalent age for this disease is young, as in our first 2 patients, early surgical intervention to preserve the fallopian tubes should be chosen when necessary, and it seems to be important for gynecologists to be aware of this disease for earlier diagnosis and appropriate surgical intervention.

Systematic review and network meta-analysis of hydrosalpinx treatment before in vitro fertilization.

OBJECTIVES: To compare different methods to treat hydrosalpinx, based on both ablative and non-ablative approaches, in infertile patients before undergoing IVF-ET. METHODS: Systematic review and network meta-analysis (NMA) of comparisons between different treatments of hydrosalpinx in infertile patients undergoing IVF. DATA SOURCES: structured searches in common citation databases. Study inclusion criteria: peer-reviewed randomized trials (RCT) or cohort studies comparing effects of salpingectomy, laparoscopic proximal tubal occlusion (LTO), insertion of intratubal device (ITD), sclerotherapy, ultrasound-guided aspiration and no treatment, on live birth, ongoing pregnancy, clinical pregnancy as main outcomes, considering also miscarriage, ectopic pregnancy and complications as secondary outcomes. Principal NMA included RCT, and aggregated NMA of RCT and observational studies was carried out. Pooled effects have been estimated by Odds Ratio (OR) and its 95% confidence interval (CI) for direct and indirect-mixed comparisons, derived from random-effects models. Imprecision and heterogeneity of NMA estimations was assessed by comparison of its 95% CI with predefined intervals for clinically relevant size of effect (OR <0.9 or >1.1). Surface under the cumulative ranking curve (SUCRA) were used to predict treatment rankings for each outcome. RESULTS: Nine RCT were included in main analysis, plus 17 additional observational studies in additional analysis. NMA of RCT did not identify significant differences in the effect of compared treatments on live birth rate, and LTO was the option with the highest value of SUCRA (0.92, mean rank: 1.2). Salpingectomy and US-aspiration associated to a significant increase of ongoing pregnancy rate compared to no treatment, according to NMA results (NMA OR: 4.35; 95% CI: 1.7, 11.14 and 2.8; 95% CI: 1.03, 7.58 respectively). Salpingectomy had the highest SUCRA value (0.88, mean rank: 1.4). NMA estimated significant increase of clinical pregnancy rate for salpingectomy compared with no treatment (NMA OR: 2.24; 95% CI: 1.3, 3.86) as well as for LTO versus no treatment (NMA OR: 2.55; 95% CI: 1.2, 5.41). Both comparisons were affected by a high grade of heterogeneity. For clinical pregnancy, LTO was the intervention with highest SUCRA (0.85; mean rank: 1.6). Regarding secondary outcomes, feasible NMA estimates did not support significant differences between treatments effects. According to aggregated NMA including randomized and observational studies, sclerotherapy showed significant beneficial effects on live birth rate compared to no treatment (NMA (OR: 4.6; 95% CI: 1.21, 17.46). Compared with untreated patients, the aggregated NMA estimates a higher ongoing pregnancy rate in patients treated with salpingectomy (NMA OR: 3.35; 95% CI: 2.12, 5.12), US-aspiration (NMA OR: 2.16; 95% CI: 1.28, 3.65) and LTO (NMA OR: 2.46; 95% CI: 1.11, 5.43). Salpingectomy and LTO produced a higher beneficial effect compared to ITD, based on both direct and indirect comparisons. Salpingectomy obtained the highest SUCRA value in rank of effects on ongoing pregnancy (0.94; mean rank: 1.2). NMA found significant effects on clinical pregnancy for comparisons between the different active management procedures compared with no treatments, with the exception of ITD insertion. LTO had more increasing effect on clinical pregnancy rate compared with US-aspiration (NMA OR: 2.04; 95% CI: 1.05, 3.97), while for the rest of the comparisons between procedures no significant differences were identified. NMA ranked LTO as the treatment with a highest SUCRA value (0.91; mean rank: 1.5). NMA prediction models identified LTO as best intervention to reduce miscarriage (SUCRA value: 0.84; mean rank: 1.8), as sclerotherapy as safer option in terms of ovarian response to IVF stimulation. CONCLUSIONS: The present NMA fails to support the effectiveness of any option to treat hydrosalpinx before IVF in order to improve live birth rates, although the beneficial effect of salpingectomy and US aspirations on ongoing pregnancy rates and of both salpingectomy and LTO on clinical pregnancy rates emerges from our analysis, which reinforces current recommendations. Based on the aggregated analyses, sclerotherapy could be a promising alternative to conventional laparoscopic techniques, combined with a favorable safety profile.

Isolated Unilateral Hydrosalpinx Torsion in a Post-Tubal Ligation Patient: A Case Report and Review of Literature.

Isolated tubal torsion of the hydrosalpinx is a rare occurrence with a varied clinical presentation, presenting a diagnostic challenge. We present a case involving the isolated torsion of the right hydrosalpinx in a 33-year patient with a history of bilateral tubal ligation who presented with an acute abdomen. Based on ultrasound and clinical findings, an initial diagnosis of ovarian torsion was considered. However, escalating pain severity led to diagnostic laparotomy, revealing torsion in the right hydrosalpinx. Subsequent right salpingectomy was done, and as the patient had undergone tubal ligation, preventive left salpingectomy was also performed. Both ovaries were preserved. The patient experienced an uneventful recovery. A literature review uncovered fewer than 50 reported cases of unilateral or bilateral isolated fallopian tube torsion post-tubal ligation. This case underscores the diagnostic challenges associated with isolated tubal torsion and emphasizes the crucial role of early surgical intervention in preventing morbidity and preserving ovaries.

Recurrent Bouts of Fever and Transient Hydrosalpinx Manifested in a Female Carrying MEFV G304R Gene Variant: A Case Report.

Familial Mediterranean fever (FMF) is an inherited autoinflammatory disease characterized by recurrent bouts of fever and serositis. Mediterranean Fever (MEFV) gene mutations may cause not just FMF but various serositis including arthritis, enterocolitis, aseptic meningitis, pulmonary disease, and pericarditis. In this report, we present a 44-year-old female carrying MEFV gene variant. She was admitted to our hospital with a high fever, right back pain during inspiration, and lower-left abdominal pain. Laboratory findings showed high inflammatory response. Computed tomography (CT) indicated pleurisy of the right lobe and inflammation of the left uterine appendage. Transvaginal sonography and magnetic resonance imaging (MRI) indicated hydrosalpinx of the left oviduct. The symptoms of recurrent fever and transient serositis suggested FMF, and abdominal pain was resolved after taking colchicine. Later, it turned out that she had MEFV gene mutation (exon2 G304R heterozygous). Although she did not meet the criteria of FMF, this is the first reported MEFV variant carrier with transient hydrosalpinx. Attacks in female patients with FMF are triggered by menstruation. Moreover, FMF and associated amyloidosis may cause both male and female infertility. Although male patients with FMF may present with acute scrotum, diagnostic criteria of FMF do not include inflammation of uterine appendages. Internal medicine physicians need to cooperate with gynecologists to diagnose female patients carrying MEFV gene variants.

Proximal tubal occlusion first or oocyte retrieval first for patients with hydrosalpinx?

PURPOSE: Our study aimed to investigate the best time to manage hydrosalpinx to improve pregnancy outcomes during in vitro fertilization-embryo transfer (IVF-ET). METHODS: Patients with hydrosalpinx who received IVF treatment were analyzed retrospectively. And two groups were included to compare the effects of different timing treatment of hydrosalpinx on IVF pregnancy outcomes, "Proximal Tubal Occlusion First Group" (Group Ligation-COH) and "Oocyte Retrieval First Group" (Group COH-Ligation). The main outcome measures included: ovarian response indexes, laboratory indexes and clinical pregnancy outcomes. Univariate and multivariate Logistic regression analysis was performed for outcome indicators, and the odds ratios (OR) and 95% confidence interval (CI) were used. RESULTS: A total of 1490 patients were included (n = 976 Ligation-COH and n = 514 COH-Ligation). The Gn starting dose and MII rate in group Ligation-COH were significantly higher than those in group COH-Ligation (203.33 ± 58.20 vs. 203.33 ± 58.20, 81.58% vs. 80.28%, P < 0.05). The number of oocytes obtained and the number of available D3 embryos in group COH-Ligation were higher than those in group Ligation-COH (15.10 ± 7.58 vs. 13.45 ± 6.42, 10.92 ± 5.81 vs. 9.94 ± 5.15, P < 0.05). Although the number of ET cycles per IVF cycle in group COH-Ligation was higher than that in group Ligation-COH (1.88 ± 1.00 vs. 1.48 ± 0.70, P < 0.05), the biochemical pregnancy rate, clinical pregnancy rate, multiple pregnancy rate, live birth rate and cumulative live birth rate in group Ligation-COH were significantly higher than those in group COH-Ligation (60.83% vs. 46.27% for biochemical pregnancy, 55.69% vs. 38.5% for clinical pregnancy, 26.18% vs. 17.74% for multiple pregnancy, 47.08% vs. 25.26% for live birth, 69.47% vs. 47.47% for cumulative live birth, P < 0.05), and the miscarriage rate in group Ligation-COH was lower than that in group COH-Ligation (10.47% vs. 17.20 for early abortion, 4.49% vs. 15.86% for late abortion, P < 0.05). In logistic regression analysis, after adjustment for age and multiple factors, the above results were still statistically significant differences (P < 0.001). For elderly patients, the clinical pregnancy rate, multiple birth rate and live birth rate in group Ligation-COH were also higher than those in group COH-Ligation (P < 0.001). No significant differences were detected for patients with diminished ovarian reserve. CONCLUSIONS: For the choice of ligation operation time, we recommend that patients choose tubal ligation first and then ovulation induction and oocyte retrieval treatment.

Ureterocele as differential diagnosis of hydrosalpinx-an interesting case from the clinical practice.

Hydrosalpinx is a common condition in women of reproductive age that correlates with infertility. A ureterocele is a dilatation of the terminal ureter within the bladder and/or urethra that occurs seldomly in adults, but can sonographically be mistaken for a hydrosalpinx. We report of a 29-year-old patient (G2/P1) who was referred in our department with secondary infertility and suspicion of hydrosalpinx. Intraoperatively, no hydrosalpinx could be visualized. Postoperatively, an intravesical cystic mass was detected, alongside a second-degree urinary retention. Sonographically, a double kidney on the left side and an accentuated calyx system could be diagnosed. Ureteroceles seem to represent a rare but still possible differential diagnosis in suspected hydrosalpinx, given the similar sonographic presentation of both conditions.

Comparison of salpingectomy and tubal occlusion for hydrosalpinx in in-vitro fertilization outcome.

The occurrence of hydrosalpinx can reduce the success rate of assisted reproductive technology. The laparoscopic salpingectomy and tubal occlusion have been shown to improve in-vitro fertilization (IVF) outcomes in this disease. The primary goal of this review was to assess and compare the IVF outcome following salpingectomy or tubal occlusion in the published literature. The authors included studies with at least one of the following outcomes: days of controlled ovarian hyperstimulation, retrieved oocyte number, fertilization rates, clinical pregnancy rate, miscarriage rate, or ectopic pregnancy rate. In conclusion, proximal tubal occlusion outperforms salpingectomy in terms of fertilization rate while offering no evident advantages in terms of days of controlled ovarian hyperstimulation, retrieved oocytes number, IVF results, or problems in treating hydrosalpinx patients prior to IVF. These data may help clinicians choose the best therapy for patients with hydrosalpinx prior to IVF.

Development of Hydrosalpinx After Prior Vaginal Hysterectomy and Bilateral Salpingectomy.

Hydrosalpinx is defined as the obstruction and fluid distension of the fallopian tube. It is most often seen in the setting of pelvic inflammatory disease, but preserved fallopian tubes or tubal segments after hysterectomy can also develop hydrosalpinx. This case report highlights an instance of painful hydrosalpinx after vaginal hysterectomy and advocates for the complete removal of fallopian tubes as the standard of care at the time of hysterectomy of any route. In this case, a 40-year-old female, G4P3104, with a history of vaginal hysterectomy and prophylactic bilateral salpingectomy for abnormal uterine bleeding and symptomatic uterine leiomyoma two years prior, presented with one month of left lower quadrant pain. She was found to have an anechoic, tubular structure adjacent to the left ovary on transvaginal ultrasound. At the time of diagnostic laparoscopy, a 10x4 centimeter (cm) dilated hydrosalpinx was found and removed. Pathology confirmed the hydrosalpinx, and the patient's pain resolved after the surgery. Given our findings of painful hydrosalpinx following incomplete bilateral salpingectomy at the time of vaginal hysterectomy, attempts at the removal of the entire fallopian tube including the fimbriae are strongly recommended to prevent the morbidity of repeated surgery.

Proteomic Profiling Identifies Candidate Diagnostic Biomarkers of Hydrosalpinx in Endometrial Fluid: A Pilot Study.

Hydrosalpinx is a fluid occlusion and distension of the fallopian tubes, often resulting from pelvic inflammatory disease, which reduces the success of artificial reproductive technologies (ARTs) by 50%. Tubal factors account for approximately 25% of infertility cases, but their underlying molecular mechanisms and functional impact on other reproductive tissues remain poorly understood. This proteomic profiling study applied sequential window acquisition of all theoretical fragment ion spectra mass spectrometry (SWATH-MS) to study hydrosalpinx cyst fluid and pre- and post-salpingectomy endometrial fluid. Among the 967 proteins identified, we found 19 and 17 candidate biomarkers for hydrosalpinx in pre- and post-salpingectomy endometrial fluid, respectively. Salpingectomy significantly affected 76 endometrial proteins, providing insights into the enhanced immune response and inflammation present prior to intervention, and enhanced coagulation cascades and wound healing processes occurring one month after intervention. These findings confirmed that salpingectomy reverses the hydrosalpinx-related functional impairments in the endometrium and set a foundation for further biomarker validation and the development of less-invasive diagnostic strategies for hydrosalpinx.

Risk factor for interstitial pregnancy following ipsilateral salpingectomy? A retrospective matched case control study.

BACKGROUND: Interstitial pregnancy may still happen even after ipsilateral salpingectomy, resulting in massive hemorrhage. Therefore, the purpose of the study is to identify risk factors associated with interstitial pregnancy following ipsilateral salpingectomy and discuss possible prevention. METHODS: We conducted a retrospective cohort study in a single, large, university-affiliated hospital. Data of 29 patients diagnosed with interstitial pregnancy following ipsilateral salpingectomy from January 2011 to November 2020 were assigned into the case group (IP group). Whereas there were 6151 patients with intrauterine pregnancy after unilateral salpingectomy in the same period. A sample size of 87 control patients was calculated to achieve statistical power (99.9%) and an α of 0.05. The age, BMI and previous salpingectomy side between the two group were adjusted with PSM at a ratio of 1:3. After PSM, 87 intrauterine pregnancy patients were successfully matched to 29 IP patients. RESULTS: After PSM, parous women were more common and intrauterine operation was more frequent in the IP group compared with control group (P<0.05). There was only one patient undergoing IVF-ET in the IP group as compared with 29 cases in the control group (3.4% vs. 33.3%, P<0.05). Salpingectomy was performed on 5 patients in the IP group and 4 patients in the control group due to hydrosalpinx (P<0.05). Logistic regression indicated that hydrosalpinx was the high risk factor of interstitial pregnancy following ipsilateral salpingectomy (OR = 8.175). CONCLUSIONS: Hydrosalpinx appears to be an independent factor contributing to interstitial pregnancy following ipsilateral salpingectomy in subsequent pregnancy.

Laparoscopic and hysteroscopic findings in women with sub-fertility and tuberculosis: A case series.

OBJECTIVE: Evaluation of hysteroscopic and laparoscopic findings in subfertile women predictive of tuberculosis. DESIGN: Retrospective case series analysis. SETTING: Tertiary hospital in India. POPULATION: A retrospective analysis of 16 784 subfertile women who had undergone diagnostic hysterolaparoscopy (DHL) was conducted between February 2014 and June 2021. METHODS: Histopathological evidence, acid-fast bacilli (AFB), culture and GeneXpert MTB/RIF assay were used to diagnose female genital tuberculosis (FGTB). Various hysteroscopic and laparoscopic findings were analysed, and a binary logistic regression assessed associations between these findings and positive diagnostic outcomes. MAIN OUTCOME MEASURES: Various hysteroscopic and laparoscopic findings correspond to tubercular manifestation. RESULTS: Of the 16,784 patients, 1083 had hysteroscopy and laparoscopy findings suggestive of tuberculosis, and 309 were diagnosed with FGTB based on diagnostic tests. Logistic regression identified variables strongly predictive of positive status outcomes; tuberculous abdomino-pelvic adhesions of various grades, isthmo-ampullary block, tubercle, tubo-ovarian mass, tuberculous hydrosalpinx, complete tubal destruction, tubal diverticula and rigid tube emerged as strong predictors. CONCLUSIONS: Logistic regression-derived predictors, alongside specific laparoscopic and hysteroscopic findings, can enhance diagnostic accuracy and clinical decision-making to start antitubercular therapy in subfertile women.

A rare case of bilateral distal segmental absence of fallopian tubes in a patient presenting with hydrosalpinx.

Isolated fallopian tube anomalies are a rare group of disorders, usually observed in otherwise asymptomatic patients. If symptomatic, the patients may present with infertility or unspecified abdominal pains. Various aetiologies have been proposed to explain this phenomenon, ranging from congenital to vascular events. Diagnosis is very challenging because in most cases those abnormalities are not easily seen on ultrasound, computed tomography, or even magnetic resonance imaging. The most objective and certain diagnosis, however, can be obtained through laparoscopy with an associated histopathological examination performed if necessary. Management of this rare group of disorders remains unclear - because the number of cases is relatively small, there is no consensus on treatment. We present a case of a 22-year-old woman with no relevant clinical history and no sexual activity with large bilateral hydrosalpinx that developed as a result of bilateral distal fallopian tube segmental absence with associated occlusion and concomitant endometriotic implants in the vicinity of the left ovarian fossa and the peritoneum of the rectouterine pouch. To our best knowledge, only a few similar cases have been described in the literature. We summarise the available descriptions of this group of pathologies, present theories that have been proposed to explain this phenomenon, and provide various classifications of those disorders.

Comparisons of different treatment outcomes in IVF/ET patients with hydrosalpinx: a retrospective study.

AIMS: To explore suggestions for clinicians on the most effective treatment for hydrosalpinx undergoing IVF-ET. MATERIALS AND METHODS: We reviewed 936 women with hydrosalpinx and 6715 tubal infertile women without hydrosalpinx who underwent IVF/ICSI between January 2014 and August 2019 in our center. Hydrosalpinx patients received different treatments including laparoscopic surgery (only salpingectomy and proximal tubal occlusion/ligation were included), ultrasonic-guided aspiration and hysteroscopic tubal occlusion. Outcomes were analyzed by One-way ANOVA, Chi-Square test and logistic regression. RESULTS: The live birth rate (LBR) of laparoscopic surgery was significantly higher compared with hydrosalpinx aspiration (48.3% vs 39.6%, p = .024). The cumulative live birth rate (CLBR) of subsequent laparoscopic surgery was significantly higher compared with subsequent hysteroscopic occlusion (65.1% vs 34.1%, p = .001) and no subsequent treatment (65.1% vs 44.9%, p < .005). Subsequent laparoscopic surgery significantly improved the CLBR of hydrosalpinx patients who received ultrasonic-guided aspiration and didn't get clinical pregnancy in fresh cycles (Odds Ratio (OR) =1.875; 95%CI = 1.041-3.378, p = .036). CONCLUSIONS: Laparoscopic surgery leads to significantly higher LBR than ultrasonic-guided aspiration and significantly higher CLBR than hysteroscopic occlusion and no treatment.

The time interval between laparoscopic tubal ligation and frozen-thawed embryo transfer does not affect the reproductive outcomes.

BACKGROUND: Hydrosalpinx may decrease implantation and pregnancy rates after embryo transfer. Laparoscopic tubal ligation after embryo freeze and before frozen-thawed embryo transfer (FET) is effective at improving reproductive outcomes for hydrosalpinx patients. This study is to find out the optimal interval between laparoscopic tubal ligation and FET. METHODS: We retrospectively analyzed 259 infertile women who performed laparoscopic tubal ligation for embryo freeze and FET. Participants were divided into three groups, based on the interval between laparoscopic tubal ligation and FET. Group I: <30 days; Group II: 31- 60 days; Group III: >60 days. Outcomes of cleavage-stage and blastocyst-stage embryo FET were analyzed respectively. RESULTS: There was no significant difference in clinical pregnancy rate, live birth rate, implantation rate, biochemical pregnancy rate, ectopic pregnancy rate, miscarriage rate and preterm birth rate among the three groups, in both cleavage-stage and blastocyst-stage embryo FET cycles. In cleavage-stage embryo FET cycle, singleton gestational age was significantly younger in group III (38.11 ± 2.28 weeks) compared with group I (39.29 ± 1.06 weeks, P = 0.001) and group II (38.96 ± 1.05, P = 0.026). Singleton birth weight was significantly heavier in group II (3.65 ± 0.32 Kg) compared with group I (3.38 ± 0.29 Kg, P = 0.001) and group III (3.35 ± 0.60 Kg, P = 0.004). Twin birth weight was significantly heavier in group III (2.72 ± 0.43 Kg) compared to group I (2.23 ± 0.67 Kg, P = 0.002). In blastocyst-stage embryo FET cycles, twin gestational age was significantly younger in group II (34.07 ± 3.18 weeks) compared with group I (35.56 ± 2.27 weeks, P = 0.049) and group III (36.50 ± 1.47 weeks, P = 0.005). Twin birth weight was significantly heavier in group III (2.71 ± 0.39 Kg) compared to group II (2.39 ± 0.67 Kg, P = 0.009). CONCLUSIONS: The duration of the interval between laparoscopic tubal ligation and FET does not affect the reproductive outcomes; however, it may affect the neonate outcomes to some extent.

Rapidly evolving pelvic lymphangioleiomyomatosis (LAM) mimicking bilateral hydrosalpinx: report of a rare case and literature review.

Lymphangioleiomyomatosis (LAM) represents a rare neoplasm affecting almost exclusively women of reproductive age. This condition mainly affects the lungs, but extrapulmonary locations such as the pelvis and the retroperitoneum are possible. Clinical evaluation and ultrasound imaging are usually non-specific, and the diagnosis is obtained through surgical excision and histopathological examination. We report a very rare case of abdominal LAM in a young female patient. A thorough literature review of this rare condition with emphasis on gynecologic implications will be presented. The patient was referred for gynecologic consultation due to pelvic pain and infertility. Unfortunately, despite prompt diagnosis and treatment, the course of the disease was severe and led to patient's exitus in a short time. We encountered an extremely rare deadly pathology mimicking a very common gynecologic condition. The gynecologist must always be alert of possible unexpected conditions that will require prompt attention.

Tryptophan residue of plasmid-encoded Pgp3 is important for Chlamydia muridarum to induce hydrosalpinx in mice.

The crucial role of plasmid-encoded protein Pgp3 in Chlamydia pathogenesis has been demonstrated in various animal models. Previous studies have revealed that the Pgp3-deficient C. muridarum mutant fails to induce hydrosalpinx after vaginal inoculation in mice. Structural analysis of C. trachomatis Pgp3 trimer has indicated that Trp234 may play a critical role in trimeric crystal packing interactions and that Tyr197 is involved at predominant cation-binding sites. In this study, we constructed C. muridarum transformants harboring Pgp3, Trp234, or Tyr197 point mutations (Pgp3W234A and Pgp3Y197A). C3H/HeJ mice infected with Pgp3W234A mutant failed to induce severe hydrosalpinx in the oviduct tissue, which largely phenocopied the full-length Pgp3-deficient C. muridarum. The Pgp3Y197A variant induced an intermediate severity of pathology. The attenuated pathogenicity caused by the Pgp3W234A mutant may be due to its decreased survival in the lower genital tracts of mice, reduced ascension to the oviduct, and milder induction of inflammatory cell infiltration in the oviduct tissue. Thus, our results point to an important amino acid residue involved in Pgp3 virulence, providing a potential therapeutic target for chlamydial infection.
