Successful transvaginal repair of a vesicouterine fistula with delayed presentation.

A G4P4 woman in her 30s with a type II vesicouterine fistula, as defined by the Jozwik classification system, presented with symptoms of menouria, vaginal menses and urinary incontinence 8 years after caesarean delivery, the time of probable origination of the fistula tract. Transvaginal ultrasound identified a fistula tract communicating between the bladder and uterus, a rare finding that many years remote from caesarean delivery. Traditional surgical technique includes laparoscopic, abdominal and endoscopic methods of repair, sometimes using a transvesical approach. Transvesical repair can be associated with subsequent inpatient hospital stays and prolonged catheterisation. Our technique proposes a transvaginal surgical approach as an outpatient procedure with decreased operating time (40 min), postoperative pain and catheterisation requirement. It is the authors' belief that a transvaginal approach is less invasive and allows for better preservation of the uterus for future pregnancies and vaginal deliveries, as desired by the patient.

[Effect of autologous platelet-rich plasma perfusion on cytokines in uterine drainage fluid of patients with intrauterine adhesions following hysteroscopic adhesiolysis].

Objective: To investigate the effect of autologous platelet-rich plasma (PRP) perfusion on the levels of cytokines in uterine drainage fluid in patients with moderate to severe intrauterine adhesions (IUA) following hysteroscopic adhesiolysis. Methods: Thirty patients with moderate to severe IUA who underwent hysteroscopic adhesiolysis at Beijing Obstetrics and Gynecology Hospital, Capital Medical University from November 2020 to March 2021 were randomly divided into two groups: the PRP group (15 patients with placement of intrauterine-suitable balloons and PRP infusion) and the control group (15 patients with placement of intrauterine-suitable balloons only). For all patients, the channel switch was opened 48 hours after the surgery. The drainage fluid of the uterine cavity was collected using syringes through the proximal end of the drainage channel switch at 24 hours after the surgery and through the drainage channel directly at 48, 72, 96, and 120 hours after the surgery, and the levels of related cytokines including platelet-derived growth factor BB (PDGF-BB), vascular endothelial growth factor A (VEGF-A), insulin-like growth factor 1 (IGF-1) and transforming growth factor-ß1 (TGF-ß1) in the drainage fluid of the uterine cavity were evaluated, respectively. Results: (1) The changes in volumes of uterine cavity drainage fluid: the total drainage fluid volumes of the PRP group and the control group in 120 hours after the surgery were (21.8±2.9) and (22.7±2.7) ml, respectively, and there was no statistically significant difference between the two groups (t=-0.847, P>0.05). No significant differences were found in the volumes of drainage fluid between the two groups at 72, 96, and 120 hours after the surgery (all P>0.05). (2) Variation in cytokine levels in the uterine cavity drainage fluid: ① PDGF-BB: median PDGF-BB levels at 24 and 48 hours after the surgery in the PRP group (6.6 and 9.6 µg/L, respectively) were significantly higher than those in the control group (4.7 and 2.7 µg/L, respectively; all P<0.05). There were no significant differences in PDGF-BB levels between the two groups at 72, 96, and 120 hours after the surgery (all P>0.05). ② VEGF-A: median VEGF-A levels at 24 and 48 hours after the surgery in the PRP group (3.5 and 2.8 µg/L, respectively) were significantly higher than those in the control group (1.6 and 1.2 µg/L, respectively; all P<0.05). There were no significant differences in VEGF-A levels between the two groups at 72, 96, and 120 hours after the surgery (all P>0.05). ③ IGF-1: median IGF-1 level at 48 hours after the surgery in the PRP group was significantly higher than that in the control group (39.5 vs 8.6 µg/L, P<0.05). No significant differences were found in IGF-1 levels at 24, 72, 96, and 120 hours after the surgery between the two groups (all P>0.05). ④ TGF-ß1: There were no significant differences in TGF-ß1 levles between the two groups at 24, 48, 72, 96, and 120 hours after the surgery (all P>0.05). Conclusions: PRP perfusion following hysteroscopic adhesiolysis may increase the levels of PDGF-BB, VEGF-A, and IGF-1 in the uterine cavity drainage fluid, which plays a beneficial role in improving wound microvascular formation, reducing adhesion reformation, and promoting endometrial regeneration and repair.

The efficacy of early office hysteroscopy in preventing intrauterine adhesions after abortion: a randomized controlled trial.

BACKGROUND: Intrauterine adhesions (IUA) are a challenging clinical problem in reproductive infertility. The most common causes are intrauterine surgery and abortions. We aimed to investigate whether early second-look office hysteroscopy can prevent IUA. METHODS: A single-center, prospective, two-armed, randomized controlled trial was designed to explore the efficacy of early office hysteroscopy after first-trimester induced abortion (suction dilatation and curettage [D&C]) and to further analyze fertility outcomes. Women aged 20-45 years undergoing suction D&C and desiring to conceive were recruited. Between October 2019 and September 2022, 66 women were enrolled, of whom 33 were allocated to group A (early hysteroscopy intervention). The women in intervention group A were planned to receive 2 times of hysteroscopies (early and late). In group B, women only underwent late (6 months post suction D&C) hysteroscopy. RESULTS: The primary outcome was the IUA rate assessed using office hysteroscopy 6 months after artificial abortion. Secondary outcomes included menstrual amount/durations and fertility outcomes. In intervention group A, 31 women underwent the first hysteroscopy examination, and 15 completed the second. In group B (late hysteroscopy intervention, 33 patients), 16 completed the hysteroscopic exam 6 months after an artificial abortion. Twenty-one women did not receive late hysteroscopy due to pregnancy. The IUA rate was 16.1% (5/31) at the first hysteroscopy in group A, and no IUA was detected during late hysteroscopy. Neither group showed statistically significant differences in the follow-up pregnancy and live birth rates. CONCLUSIONS: Early hysteroscopy following suction D&C can detect intrauterine lesions. IUA detected early by hysteroscopy can disappear on late examination and become insignificant for future pregnancies. Notably, the pregnancy outcomes showed a favorable trend in the early hysteroscopy group, but there were no statistically significant differences.

Prolonged adhesiolysis to pregnancy interval is associated with placenta accreta spectrum in women with intrauterine adhesion.

BACKGROUND: Both the trauma of endometrium and hysteroscopic adhesiolysis can lead to a high rate of placenta accreta spectrum (PAS) in women with intrauterine adhesion (IUA). This study analysed the impact of time interval from adhesiolysis to pregnancy on PAS in IUA women. METHODS: Patients diagnosed with IUA who underwent adhesiolysis in Anhui Women and Children's Medical Centre between January 2016 and December 2020 were included in this case-series study. Clinical data were obtained from electronic medical records and telephone interviews. RESULTS: Among a total of 102 IUA women with successful pregnancies, 8 (7.8%) suffered from miscarriages with PAS, and 94 (92.2%), 47 with PAS and 47 without PAS, had successful delivery. The total prevalence of PAS in pregnant women with IUA was 53.9% (55/102). The average time from adhesiolysis to pregnancy in the PAS group was significantly longer than in the non-PAS group (14.2 ± 5.7 vs. 10.3 ± 4.4 months, p = 0.000). Regression analysis showed that AFS grade (OR = 7.40, 95% CI 1.38-39.73, p = 0.020) and adhesiolysis to pregnancy interval time between 12 and 24 months (OR = 12.09, 95% CI 3.76-38.83, p = 0.000) were closely related to PAS. A Kaplan-Meier analysis showed the median interval time to PAS was 16.00 months (95% CI 15.11-16.89). CONCLUSIONS: We assume that prolonged adhesiolysis to pregnancy interval may be considered a significant risk factor for PAS in IUA women.

This case-series study included patients diagnosed with intrauterine adhesion who underwent adhesiolysis in Anhui Women and Children's Medical Centre between January 2016 and December 2020. Clinical data were obtained from electronic medical records and telephone interviews. We assume that prolonged adhesiolysis to pregnancy interval may be considered a significant risk factor for placenta accreta spectrum in intrauterine adhesion women.

A Case Report of Uterine Torsion in a Postmenopausal Female with a Large Leiomyoma.

This case report discusses a diagnosis of uterine torsion in an 84-year-old woman who presented with five days of right lower quadrant abdominal pain, nausea, vomiting, constipation, and poor intake. Computed tomography (CT) imaging demonstrated a whorled configuration at the junction of the cervix and lower uterine segment, with the left gonadal vein crossing midline, and two previously known right leiomyomas now appearing on the left. These findings were consistent with the diagnosis of uterine torsion. She then underwent an urgent exploratory laparotomy, and the uterus was found to be dextroverted 270 degrees, with dark mottled purple tissue and engorged vessels. A supracervical hysterectomy and bilateral salpingo-oopherectomy were performed. Final pathology demonstrated extensive necrosis. This case reviews the classic presentation and imaging findings for the rare diagnosis of uterine torsion and options for management of both non-gravid and gravid patients.

Chronic endometritis multiplies the recurrence risk of endometrial polyps after transcervical resection of endometrial polyps: a prospective study.

BACKGROUND: To investigate the impact of chronic endometritis (CE) on the recurrence of endometrial polyps (EPs) in premenopausal women after transcervical resection of endometrial polyps (TCRP). METHODS: This prospective study enrolled 507 women who underwent TCRP between January 1, 2022 and December 31, 2022. The patients were divided into a CE group (n = 133) and non-CE group (n = 374) based on the expression of CD138 in the endometrium. The EP recurrence rate at 1 year after TCRP was compared between the CE and non-CE groups and between groups with mild CE and severe CE. The impact of CD138 expression by resected EPs on EP recurrence also was investigated. RESULTS: The EP recurrence rate at 1 year post-TCRP was higher in the CE group than in the non-CE group (25.6% vs. 10.4%) and also higher in the severe CE group than in the mild CE group (34.5% vs. 18.7%). Additionally, the EP recurrence rate was higher among patients with CD138-expressing EPs than among those with EPs lacking CD138 expression (30.5% vs. 6.5%). The odds ratio (OR) for EP recurrence in the CE cohort compared with the non-CE cohort was 3.10 (95% confidence interval [CI] 1.84-5.23) after adjustment for EP number and precautions against EP recurrence. The ORs for EP recurrence in patients with mild CE and severe CE were 2.21 (95%CI 1.11-4.40) and 4.32 (95%CI 2.26-8.26), respectively. Similarly, the OR for EP recurrence in cases with CD138-expressing EPs relative to cases with EPs lacking CD138 expression was 6.22 (95%CI 3.59-10.80) after adjustment for EP number and precautions against EP recurrence. CONCLUSIONS: CE multiplied the recurrence rate of EPs in premenopausal women after TCRP, and this effect positively correlated with CE severity. CD138 expression by EPs also was associated with a higher risk for EP recurrence.

Inpatient Hospital Costs and Route of Hysterectomy for Management of Benign Uterine Disease in the 90-Day Global Billing Period.

OBJECTIVE: To compare inpatient hospital costs and complication rates within the 90-day global billing period among routes of hysterectomy. METHODS: The Premier Healthcare Database was used to identify patients who underwent hysterectomy between 2000 and 2020. Current Procedural Terminology codes were used to group patients based on route of hysterectomy. Comorbidities and complications were identified using International Classification of Diseases codes. Fixed, variable, and total costs for inpatient care were compared. Fixed costs consist of costs that are set for the case, such as operating room time or surgeon costs. Variable costs include disposable and reusable items that are billed additionally. Total costs equal fixed and variable costs combined. Data were analyzed using analysis of variance, t test, and χ 2 test, as appropriate. Factors independently associated with increased total costs were assessed using linear mixed effects models. Multivariate logistic regression was performed to evaluate associations between the route of surgery and complication rates. RESULTS: A cohort of 400,977 patients were identified and grouped by route of hysterectomy. Vaginal hysterectomy demonstrated the lowest inpatient total cost ($6,524.00 [interquartile range $4,831.60, $8,785.70]), and robotic-assisted laparoscopic hysterectomy had the highest total cost ($9,386.80 [interquartile range $6,912.40, $12,506.90]). These differences persisted with fixed and variable costs. High-volume laparoscopic and robotic surgeons (more than 50 cases per year) had a decrease in the cost difference when compared with costs of vaginal hysterectomy. Abdominal hysterectomy had a higher rate of complications relative to vaginal hysterectomy (adjusted odds ratio [aOR] 1.52, 95% CI, 1.39-1.67), whereas laparoscopic (aOR 0.85, 95% CI, 0.80-0.89) and robotic-assisted (aOR 0.92, 95% CI, 0.84-1.00) hysterectomy had lower rates of complications compared with vaginal hysterectomy. CONCLUSION: Robotic-assisted hysterectomy is associated with higher surgical costs compared with other approaches, even when accounting for surgeon volume. Complication rates are low for minimally invasive surgery, and it is unlikely that the robotic-assisted approach provides an appreciable improvement in perioperative outcomes.

The use of oral nomegestrol acetate/estradiol in rapid and random start preparation of endometrium before office hysteroscopic polypectomies: A multicenter, prospective, randomized controlled trial.

OBJECTIVE: To evaluate the use of oral nomegestrol acetate/estradiol in random start rapid preparation of endometrium before office hysteroscopic polypectomy. STUDY DESIGN: Multicenter, prospective, randomized controlled trial. SETTING: University hospitals. PARTICIPANTS: 80 adult women undergoing office hysteroscopic polypectomy between January 2023 and March 2024 were randomized to intervention (n = 40) or control (n = 40). Exclusion criteria included the presence of endouterine pathology other than endometrial polyps solely. METHODS: Subjects in the intervention group were treated with oral nomegestrol acetate/estradiol 1.5 mg/2.5 mg/day started taking the drug from an indefinite time in the menstrual cycle (random start) for 14 days. Subjects in the control group did not receive any pharmaceutical treatment and underwent polypectomy between days 8 and 11 of the menstrual cycle. RESULTS: On the day of the procedure, the difference in pre- and post-office hysteroscopic polypectomy endometrial ultrasound thickness was statistically significant between the two groups, with endometrial thickness in both measurements being thinner for the intervention group (p < 0.001). In the nomegestrol acetate/estradiol-treated group, compared with the control, there was also a statistically significant difference in the physician's assessment of the quality of endometrial preparation (p < 0.001), the quality of visualization of the uterine cavity (p < 0.001), and satisfaction with the performance of the procedure (p < 0.001). Finally, all surgical outcomes analyzed were better in the treatment group. CONCLUSION: Treatment with nomegestrol acetate/estradiol could provide rapid, satisfactory and low-cost preparation of the endometrium before office polypectomy, thus improving surgical performance and woman's compliance.

Multimodal learning system integrating electronic medical records and hysteroscopic images for reproductive outcome prediction and risk stratification of endometrial injury: a multicenter diagnostic study.

OBJECTIVE: To develop a multimodal learning application system that integrates electronic medical records (EMR) and hysteroscopic images for reproductive outcome prediction and risk stratification of patients with intrauterine adhesions (IUAs) resulting from endometrial injuries. MATERIALS AND METHODS: EMR and 5014 revisited hysteroscopic images of 753 post hysteroscopic adhesiolysis patients from the multicenter IUA database we established were randomly allocated to training, validation, and test datasets. The respective datasets were used for model development, tuning, and testing of the multimodal learning application. MobilenetV3 was employed for image feature extraction, and XGBoost for EMR and image feature ensemble learning. The performance of the application was compared against the single-modal approaches (EMR or hysteroscopic images), DeepSurv and ElasticNet models, along with the clinical scoring systems. The primary outcome was the 1-year conception prediction accuracy, and the secondary outcome was the assisted reproductive technology (ART) benefit ratio after risk stratification. RESULTS: The multimodal learning system exhibited superior performance in predicting conception within 1-year, achieving areas under the curves of 0.967 (95% CI: 0.950-0.985), 0.936 (95% CI: 0.883-0.989), and 0.965 (95% CI: 0.935-0.994) in the training, validation, and test datasets, respectively, surpassing single-modal approaches, other models and clinical scoring systems (all P<0.05). The application of the model operated seamlessly on the hysteroscopic platform, with an average analysis time of 3.7±0.8 s per patient. By employing the application's conception probability-based risk stratification, mid-high-risk patients demonstrated a significant ART benefit (odds ratio=6, 95% CI: 1.27-27.8, P=0.02), while low-risk patients exhibited good natural conception potential, with no significant increase in conception rates from ART treatment (P=1). CONCLUSIONS: The multimodal learning system using hysteroscopic images and EMR demonstrates promise in accurately predicting the natural conception of patients with IUAs and providing effective postoperative stratification, potentially contributing to ART triage after IUA procedures.

Hysterectomy Techniques and Outcomes for Benign Large Uteri: A Systematic Review.

OBJECTIVE: To identify the optimal hysterectomy approach for large uteri in gynecologic surgery for benign indications from a perioperative morbidity standpoint. DATA SOURCES: PubMed and Embase databases were searched from inception through September 19, 2022. Meta-analyses were conducted as feasible. METHODS OF STUDY SELECTION: This review included studies that compared routes of hysterectomy with or without bilateral salpingo-oophorectomy for large uteri (12 weeks or more or 250 g or more) and excluded studies with any concurrent surgery for pelvic organ prolapse, incontinence, gynecologic malignancy, or any obstetric indication for hysterectomy. TABULATION, INTEGRATION, AND RESULTS: The review included 25 studies comprising nine randomized trials, two prospective, and 14 retrospective nonrandomized comparative studies. Studies were at high risk of bias. There was lower operative time for total vaginal hysterectomy compared with laparoscopically assisted vaginal hysterectomy (LAVH) (mean difference 39 minutes, 95% CI, 18-60) and total vaginal hysterectomy compared with total laparoscopic hysterectomy (mean difference 50 minutes, 95% CI, 29-70). Total laparoscopic hysterectomy was associated with much greater risk of ureteral injury compared with total vaginal hysterectomy (odds ratio 7.54, 95% CI, 2.52-22.58). There were no significant differences in bowel injury rates between groups. There were no differences in length of stay among the laparoscopic approaches. For LAVH compared with total vaginal hysterectomy, randomized controlled trials favored total vaginal hysterectomy for length of stay. When rates of blood transfusion were compared between these abdominal hysterectomy and robotic-assisted total hysterectomy routes, abdominal hysterectomy was associated with a sixfold greater risk of transfusion than robotic-assisted total hysterectomy (6.31, 95% CI, 1.07-37.32). Similarly, single studies comparing robotic-assisted total hysterectomy with LAVH, total laparoscopic hysterectomy, or total vaginal hysterectomy all favored robotic-assisted total hysterectomy for reduced blood loss. CONCLUSION: Minimally invasive routes are safe and effective and have few complications. Minimally invasive approach (vaginal, laparoscopic, or robotic) results in lower blood loss and shorter length of stay, whereas the abdominal route has a shorter operative time.

Extended balloon stent placement for reducing intrauterine adhesion recurrence: a retrospective cohort study.

RESEARCH QUESTION: What are the efficacy, safety and reproductive outcomes of intrauterine balloon stent placement for 4 or 6 weeks after hysteroscopic adhesiolysis? DESIGN: This retrospective cohort study was conducted at a university-affiliated hospital, and included 155 women with moderate to severe intrauterine adhesions who underwent hysteroscopic adhesiolysis between March 2016 and December 2019. Participants were divided according to whether the heart-shaped balloon stent was left in place for 4 (group 1) or 6 (group 2) weeks after surgery. Stents removed at the second-look hysteroscopy 4 or 6 weeks after surgery were sent for culturing of common bacteria. The incidence of adhesion reformation, adhesion score reduction, bacterial colonization of the intrauterine balloon stent, live birth rate and time to live birth were analysed. RESULTS: Group 2 had a significantly lower adhesion reformation rate (45.7% versus 28.2%, P = 0.024) and a more significant reduction in adhesion score (5.2 ± 2.1 versus 6.3 ± 2.2, P = 0.003) compared with group 1. However, no statistical difference was observed in the percentage of bacterial colonization of the intrauterine balloon stent (55.9% versus 66.7%, P = 0.174), live birth rate (52.4% versus 42.3%, P = 0.331) or time to live birth (hazard ratio 1.09, 95% confidence interval 0.60-1.96, P = 0.778) between the two groups. CONCLUSIONS: Extending intrauterine balloon stent use from 4 to 6 weeks further reduces the adhesion reformation rate after hysteroscopic adhesiolysis in patients with moderate to severe intrauterine adhesion. No increase in bacterial colonization of the balloon stent was observed. Extending the duration of intrauterine balloon stent placement did not significantly affect live birth rates.

Uterine mesothelial cysts mimicking ovarian cysts in a primipara patient with a history of Cesarean section: A case report and review of the literature.

OBJECTIVE: We describe a rare case of uterine mesothelial cysts mimicking ovarian cysts in a primipara patient with a history of Cesarean section. CASE REPORT: A 39-year-old female patient with history of Cesarean section presented with dysmenorrhea. Sonography revealed that a hypoechoic and anechoic multicystic complex, which was located on the right side of the pelvic cavity, had infiltrated the adjacent posterior wall of the uterus, and it was preoperatively misdiagnosed as ovarian cysts with suspected endometrioma. Laparoscopic surgery revealed multiple cystic lesions filled with clear yellow fluid on the posterior uterine wall instead of the adnexa. Laparoscopic uterine cystectomy was performed, and the patient's recovery was uneventful. Pathohistological and immunohistochemical examinations confirmed the diagnosis of uterine mesothelial cysts. CONCLUSION: Uterine mesothelial cysts should be considered in the differential diagnosis of pelvic lesions. Increasing the awareness of this rare disease can contribute to improved evaluation, decision-making, and disease management.

Recognizing uterine torsion as a differential diagnosis in pregnant cats with severe anemia to provide appropriate and timely care in the absence of a definitive presurgical diagnosis.

A pregnant female domestic longhair cat ~8 mo of age was referred to the Western College of Veterinary Medicine (Saskatoon, Saskatchewan) for a diagnostic evaluation of severe anemia (PCV: 10.8%) after a 2-day period of lethargy. A CBC, serum biochemistry profile, FeLV/FIV testing, and abdominal radiographs were completed and did not determine a cause for the anemia. Abdominal ultrasonography identified 1 viable and 6 nonviable and fetuses, anechoic fluid in the uterus, and a mild volume of peritoneal effusion. A whole-blood transfusion and C-section with ovariohysterectomy were performed even though a definitive presurgical diagnosis for the anemia had not yet been established. Exploratory surgery revealed a left uterine horn torsion with a necrotic base, severe congestion, and 7 nonviable fetuses. Following surgery, the queen made a full clinical recovery. Key clinical message: Uterine torsion can be easily overlooked as a cause of severe anemia due to the relative infrequency of this condition in cats and the low sensitivity of ultrasonography to provide a definitive presurgical diagnosis. Client communication must emphasize the need for a prompt surgical intervention to establish the diagnosis and to save the cat, despite poor rates of neonatal survival. Once the animal is stabilized after surgery, further diagnostic tests and procedures are indicated if the cause of anemia has not yet been identified.

Reconnaître la torsion utérine comme un diagnostic différentiel chez les chattes gestantes souffrant d'anémie sévère afin de fournir des soins appropriés et opportuns en l'absence d'un diagnostic pré-chirurgical définitif. Une chatte domestique à poils longs, âgée d'environ 8 mois, a été référée au Western College of Veterinary Medicine (Saskatoon, Saskatchewan) pour une évaluation diagnostique d'anémie sévère (hématocrite : 10,8 %) après une période de léthargie de 2 jours. Une formule sanguine complète, un profil biochimique sérique, des tests FeLV/FIV et des radiographies abdominales ont été réalisés et n'ont pas permis de déterminer la cause de l'anémie. L'échographie abdominale a identifié 1 foetus viable et 6 non viables, du liquide anéchoïque dans l'utérus et un léger volume d'épanchement péritonéal. Une transfusion de sang total et une césarienne avec ovariohystérectomie ont été réalisées même si le diagnostic pré-chirurgical définitif de l'anémie n'avait pas encore été établi. La chirurgie exploratoire a révélé une torsion de la corne utérine gauche avec une base nécrotique, une congestion sévère et 7 foetus non viables. Après l'opération, la chatte s'est complètement rétablie cliniquement.Message clinique clé:La torsion utérine peut facilement être négligée comme cause d'anémie sévère en raison de la rareté relative de cette affection chez le chat et de la faible sensibilité de l'échographie pour fournir un diagnostic pré-chirurgical définitif. La communication avec le client doit souligner la nécessité d'une intervention chirurgicale rapide pour établir le diagnostic et sauver le chat, malgré de faibles taux de survie néonatale. Une fois l'animal stabilisé après la chirurgie, d'autres tests et procédures de diagnostic sont indiqués si la cause de l'anémie n'a pas encore été identifiée.(Traduit par Dr Serge Messier).

Minimally invasive treatment of uterine necrosis with favorable outcomes: an uncommon case presentation and literature review.

BACKGROUND: Uterine necrosis is a rare condition and is considered a life-threatening complication. However, cases of uterine necrosis were rarely reported, particularly those caused by infection. In terms of treatment, no minimally invasive treatment for uterine necrosis has been reported, and total hysterectomy is mostly considered as the treatment option. OBJECTIVE: The article specifically focuses on minimally invasive treatments and provides a summary of recent cases of uterine necrosis. CASE PRESENTATION: We report the case of a 28-year-old patient gravid 1, para 0 underwent a cesarean section after unsuccessful induction due to fetal death. She presented with recurrent fever and vaginal discharge. The blood inflammation markers were elevated, and a CT scan revealed irregular lumps with low signal intensity in the uterine cavity. The gynecological examination revealed the presence of gray and white soft tissue, approximately 5 cm in length, exuding from the cervix. The secretions were found to contain Fusobacterium necrophorum, Escherichia coli, and Proteus upon culturing. Given the patient's sepsis and uterine necrosis caused by infection, laparoscopic exploration uncovered white pus and necrotic tissue openings in the anterior wall of the uterus. The necrotic tissue was removed during the operation, and the uterus was repaired. Postoperative pathological findings revealed complete degeneration and necrosis of fusiform cell-like tissue. Severe uterine necrosis caused by a multi-drug resistant bacterial infection was considered after the operation. She was treated with antibiotics for three weeks and was discharged after the infection was brought under control. The patient expressed satisfaction with the treatment plan, which preserved her uterus, maintained reproductive function, and minimized the extent of surgery. CONCLUSION: Based on the literature review of uterine necrosis, we found that it presents a potential risk of death, emphasizing the importance of managing the progression of the condition. Most treatment options involve a total hysterectomy. A partial hysterectomy reduces the extent of the operation, preserves fertility function, and can also yield positive outcomes in the treatment of uterine necrosis, serving as a complement to the overall treatment of this condition.

Comparing the efficacy and pregnancy outcome of intrauterine balloon and intrauterine contraceptive device in the prevention of adhesion reformation after hysteroscopic adhesiolysis in infertile women: a prospective, randomized, controlled trial study.

STUDY OBJECTIVE: To evaluate the efficacy and pregnancy outcomes of intrauterine balloon and intrauterine contraceptive devices in the prevention of adhesion reformation following hysteroscopic adhesiolysis in infertile women with moderate to severe intrauterine adhesion. DESIGN: A prospective, randomized, controlled trial study. SETTING: A tertiary university hospital. PATIENTS: A total of 130 patients with moderate (American Fertility Society [AFS] score of 5-8) and severe (AFS score of 9-12) intrauterine adhesions were recruited. INTERVENTIONS: 86 patients were evenly allocated to group treated with an IUD for 1 month and group treated with an IUD for 2 months. 44 patients were allocated to group treated with a Foley catheter balloon.(IUD: Yuangong IUD). MEASUREMENTS AND MAIN RESULTS: The primary outcome measures were the AFS score, endometrial thickness, and pregnancy outcome. After hysteroscopy, the AFS score was significantly decreased(P<0.05), whereas endometrial thickness was significantly increased across the three groups(P<0.001). Notably, the decline in the AFS score in the balloon group was greater than that in the IUD-1-month group and IUD-2-month group(P<0.01), with no significant difference between the IUD groups(P = 0.298). Lastly, In addition, the extent of the increase in endometrial thickness(P = 0.502) and the pregnancy outcomes(P = 0.803) in the three groups were not significantly different. CONCLUSION: Inserting a balloon or placing an IUD for one or two months can effectively lower the risk of adhesion recurrence and restore the shape of the uterine cavity. While the therapeutic effect of the balloon was superior to that of the IUD, no significant differences were observed in the one-month and two-month IUD groups. TRIAL REGISTRATION: This research was registered in the Chinese Clinical Trial Registry ( http://www.chictr.org.cn/enIndex.aspx ); Clinical trial registry identification number: ChiCTR-IOR-17,011,943 ( http://www.chictr.org.cn/showprojen.aspx?proj=17979 ). Date of trial registration: July 11, 2017.

Short-term reproductive outcomes analysis and prediction of the modified uterine stent treatment for mild to moderate intrauterine adhesions: experience at a single institution.

BACKGROUND: To evaluate the efficacy of modified uterine stent in the treatment of mild-to-moderate intrauterine adhesions and explore the relative indicators affecting prognosis prediction. METHODS: A total of 115 patients with mild-to-moderate intrauterine adhesions received a modified uterine stent placement after hysteroscopy adhesiolysis. The second-look hysteroscopy operated after 3 months surgery, and the third-look hysteroscopy operated after 6 months surgery if necessary. The stent was removed when the cavity shape was repaired, then the reproductive outcomes were followed up one year. RESULTS: Menstrual blood volume, endometrial thickness and volume had increased significantly after 3 months surgery. The rates of cavity repaired were 86.96% (100/115) after 3 months surgery and 100% (115/115) after 6 months surgery cumulatively. Endometrial thickness after 3-months surgery was positively associated with uterine cavity shape repaired (P<0.01). The receive operating characteristic (ROC) curve showed the rate of uterine cavity shape repaired predicted by the model was 0.92, based on the endometrial thickness after 3-months surgery. The rate of pregnancy was 86.09% (99/115) in one year, while the rate of miscarriage accounted for 26.26% (26/99). The median time interval between stent removal and subsequent conception was 3 months. It showed adhesion recurrence was the risk factor for subsequent pregnancy (P<0.01). CONCLUSIONS: A modified uterine stent placement under hysteroscopy was an effective approach for mild-to-moderate intrauterine adhesions, which is easy to operate and worthy for clinical promotion. Endometrial thickness measured by ultrasonography probably has predictive value in adhesion recurrence and subsequent pregnancy. TRIAL REGISTRATION: ChiCTR2100051524.

Analysis of factors affecting the prognosis of patients with intrauterine adhesions after transcervical resection of adhesions.

OBJECTIVES: To study the factors affecting the prognosis of patients with intrauterine adhesions (IUAs) after transcervical resection of adhesions (TCRA), analyze the reproductive outcome, and guide prognostic improvements. DESIGN: Prospective study. PATIENTS: Our study included 292 patients diagnosed with IUAs who underwent follow-up office hysteroscopy at Shenyang Women's and Children's Hospital between June 2018 and June 2022. INTERVENTIONS: Patients were divided into case (52 patients whose hysteroscopy results indicated the presence of IUAs) and nocase (240 patients whose uterine cavity had returned to normal shape without obvious adhesion) groups on the basis of the results of a 2-month follow-up hysteroscopy following TCRA. Clinical data were collected and compared with various influencing factors, and the combined effect of these factors was assessed using multifactorial logistic regression analysis. A nomogram prediction model was constructed and internally validated on the basis of multifactorial analysis. MAIN OUTCOME MEASURES: Intrauterine re-adhesion was observed at a 2-month follow-up after TCRA. RESULTS: Postoperative re-adhesion occurred in 52 of 292 patients with IUAs. Multifactorial binary logistic regression analysis showed that IUA barrier gel reapplication 5 days after TCRA was a protective factor. In contrast, the preoperative American Fertility Society scores demonstrated that severe IUAs and chronic endometritis were risk factors. The results of the multifactorial analysis were used to build a nomogram model, and the area under the curve value of the nomogram model for predicting postoperative recurrence was 0.914 (95% confidence interval: 0.864-0.956). The bootstrap method was subsequently used to resample 1,000 times for internal validation. The results showed that the internal validation C-index was 0.9135, and the calibration and ideal curves were well-matched. CONCLUSION: The prognosis of patients with IUAs after TCRA is related to the severity of preoperative IUAs, presence of chronic endometritis, and IUA barrier gel reapplication 5 days after TCRA. Therefore, clinicians should monitor patients using targeted data to reduce recurrence risk after TCRA and improve the prognosis of patients with IUAs.

Manually driven versus motor driven hysteroscopic tissue removal system for polypectomy: Long-term results.

OBJECTIVE: The aim of this follow-up study is to compare a manually driven hysteroscopic tissue removal system (ResectrTM 9 Fr) with a motor driven system (TruclearTM) in terms of long-term clinical outcomes such as abnormal uterine bleeding and polyp recurrence. STUDY DESIGN: This is a follow-up of a multicenter randomized controlled trial comparing a manually and motor driven hysteroscopic tissue removal system for polypectomy. This prospective cohort study was performed at Ghent University Hospital (Ghent, Belgium) and Catharina Hospital Eindhoven (Eindhoven, the Netherlands). The trial was registered at Clinicaltrials.gov (Trial ID = NCT05337605, April 2022). Seventy-five women with abnormal uterine bleeding who participated in the randomized controlled trial and had pathological confirmation of the diagnosis of an endometrial polyp, were contacted. Fifty-five women (70.67 %) were willing to participate in this follow-up study. The primary outcome was the recurrence and/or persistence of abnormal uterine bleeding and the time to the recurrence of abnormal uterine bleeding. Secondary outcomes were polyp recurrence and time to polyp recurrence, symptom relief, satisfaction score regarding symptom relief and general satisfaction score regarding the surgical procedure. RESULTS: In the manually driven group, the mean time to the recurrence or persistence of abnormal uterine bleeding was 26 months (95 % CI 20 - 32). In the motor driven group, the mean time to the recurrence or persistence of abnormal uterine bleeding was 29 months (95 % CI 23- 34). A log-rank test showed a non-significant difference between both groups (P =.77). There was no significant difference in polyp recurrence (P =.22) or symptom relief between the two groups (P =.67). Additionally, the groups did not differ in satisfaction scores regarding symptoms or polypectomy (P =.16 and P =.61, respectively). CONCLUSION: This long-term follow-up study showed no statistically significant difference in the recurrence and persistence of abnormal uterine bleeding between a manually and motor driven hysteroscopic tissue removal system for polypectomy.
