Evaluating resectoscopy and the levonorgestrel intrauterine system for intermenstrual bleeding associated with cesarean scar defects: A retrospective study of treatment outcomes. J Obstet Gynaecol Res 2024; 50:253-261. [PMID: 37990626 DOI: 10.1111/jog.15840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 11/12/2023] [Indexed: 11/23/2023]
Abstract
AIM To compare and evaluate the efficacy of the levonorgestrel-releasing intrauterine system (LNG-IUD) and resectoscopy remodeling procedure for intermenstrual bleeding associated with previous cesarean delivery scar defect (PCDS). METHODS A retrospective comparative study was conducted on patients with PCDS receiving LNG-IUD (levonorgestrel 20 μg/24 h, N = 33) or resectoscopy remodeling (N = 27). Treatment outcomes were compared over 1, 6, and 12 months. Outcomes in patients with a retroverted or large uterus size, defect size, and local vascularization also were evaluated. RESULTS At 12 months post-treatment, there were no significant differences between groups in efficacy rate; however, the reduction of intermenstrual bleeding days was higher in the LNG-IUD group than in the resectoscopy group (13.6 vs. 8.5 days, p = 0.015). Within the first year, both groups experienced a reduction in bleeding days, but the decrease was greater in the LNG-IUD group. Individuals exhibiting increased local vascularization at the defect site experienced more favorable outcomes in the LNG-IUD group than the resectoscopy group (p = 0.016), and who responded poorly tended to have a significantly larger uterus in the LNG-IUD group (p = 0.019). No significant differences were observed in treatment outcomes for patients with a retroverted uterus or large defect in either group. CONCLUSIONS Our findings support that the LNG-IUD is as effective as resectoscopy in reducing intermenstrual bleeding days associated with PCDS and can be safely applied to patients without recent fertility aspirations. Patients with increased local vascularization observed during hysteroscopy may benefit more from LNG-IUD intervention than resectoscopy.

[PMID: 37537601 PMCID: PMC10398967 DOI: 10.1186/s12905-023-02539-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Accepted: 07/12/2023] [Indexed: 08/05/2023] Open
Abstract
BACKGROUND Uterine diverticulum is classified into congenital and acquired types. The acquired type is caused by caesarean scar syndrome, which occurs after caesarean section. There are no detailed reports on diverticulum after enucleation of uterine fibroids. Most cases are treated with hysteroscopy or laparoscopy, but a management consensus is lacking. We treated a patient with a uterine diverticulum that had formed after uterine fibroid enucleation by combining hysteroscopic and laparoscopic treatments. CASE PRESENTATION The patient was a 37-year-old Japanese woman, G1P0. A previous doctor had performed abdominal uterine myomectomy for a pedunculated subserosal uterine fibroid on the right side of the posterior wall of the uterus near the internal cervical os. Menstruation resumed postoperatively, but a small amount of dark-red bleeding persisted. MRI two months after the myomectomy revealed a diverticulum-like structure 3 cm in diameter, communicating with the uterine lumen, on the right side of the posterior wall of the uterus. Under suspicion of uterine diverticulum after uterine fibroid enucleation, the patient sought treatment at our hospital approximately four months after the myomectomy. Through a flexible hysteroscope, a 5-mm-diameter fistula was observed in the posterior wall of the uterus, and a contrast-enhanced pocket, measuring approximately 3 cm, was located behind it. Uterine diverticulum following enucleation of a uterine fibroid was diagnosed, and surgery was thus deemed necessary. The portion entering the fistula on the internal cervical os side was resected employing a hysteroscope. Intra-abdominal findings included a 4-cm mass lesion on the posterior wall on the right side of the uterus. The mass was opened, and the cyst capsule was removed. A 5-mm fistula was detected and closed with sutures. Resuturing was not performed after dissection of the right round ligament due to tension. The postoperative course has been good to date, with no recurrence. CONCLUSION Uterine diverticula after myomectomy may be treated with a combined laparoscopic and hysteroscopic approach, similar to caesarean scar syndrome.

Abstract
Cesarean scar disorder (CSD) is an entity recently defined as uterine niche with at least one primary or 2 secondary symptoms. CSDs can be visualized by hysterosalpingography, transvaginal sonography, saline infusion sonohysterography, hysteroscopy, and magnetic resonance imaging, but diagnosis should be performed by exams able to measure the residual myometrial thickness (RMT). Although there is a limited number of studies evaluating fertility and reproductive outcomes after different types of surgery, the following consideration should be kept in mind. Asymptomatic women should not be operated with the hope of improving obstetrical outcomes. It is reasonable to consider hormone therapy for CSDs as a symptomatic treatment in women who no longer wish to conceive and have no contraindications. In case of failure of or contraindications to medical treatment, surgery should be offered according to the severity of symptoms, including infertility, the desire or otherwise to preserve the uterus, the size of the CSD, and RMT measurement. Hysteroscopy is considered to be more of a resection than a repair, so women who desire pregnancy should be excluded from this technique in case of RMT <3 mm. In this instance, repair is essential and can only be achieved by a laparoscopic or vaginal approach. The benefit of laparoscopic approach seems to persist after subsequent CS. Women with CSDs need to be given complete information, including available literature, before any treatment decision is made.

Comparing levonorgestrel intrauterine system with hysteroscopic niche resection in women with postmenstrual spotting related to a niche in the uterine cesarean scar: a randomized, open-label, controlled trial. Am J Obstet Gynecol 2023; 228:712.e1-712.e16. [PMID: 36935068 DOI: 10.1016/j.ajog.2023.03.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 03/07/2023] [Accepted: 03/08/2023] [Indexed: 03/19/2023]
Abstract
BACKGROUND Postmenstrual spotting and chronic pelvic pain after cesarean delivery are associated with the presence of niches. Levonorgestrel intrauterine system (52 mg) and hysteroscopic niche resection have been shown to relieve niche-related symptoms at 6 months after the intervention. OBJECTIVE This trial aimed to compare the effectiveness of 52-mg levonorgestrel intrauterine system with that of hysteroscopic niche resection in reducing niche-related postmenstrual spotting. STUDY DESIGN This randomized, open-label, controlled trial was conducted at a medical center in Shanghai, China. Women with symptoms of postmenstrual spotting after cesarean delivery, with a niche depth of at least 2 mm and residual myometrium of at least 2.2 mm on magnetic resonance imaging, and no intention to conceive within the next year were randomly assigned to receive treatment with 52-mg levonorgestrel intrauterine system or hysteroscopic niche resection. The primary outcome was the reduction in postmenstrual spotting at 6 months after randomization, defined as the percentage of women with a reduction of at least 50% in spotting days relative to baseline. Efficacy and safety were assessed using intention-to-treat analysis. RESULTS Between September 2019 and January 2022, 208 women were randomized into the levonorgestrel intrauterine system group (N=104) or the hysteroscopic niche resection group (N=104). At the 6-month follow-up, a 50% reduction in spotting had occurred in 78.4% (80/102) of women in the levonorgestrel intrauterine system group and in 73.1% (76/104) of women in the hysteroscopic niche resection group (relative risk, 1.07 [95% confidence interval, 0.92-1.25]; P=.370). Spotting decreased over time (Ptrend=.001), with a stronger reduction observed in the levonorgestrel intrauterine system group (P=.001). There was also a significant interaction between time and treatment (P=.007). From 9 months onward, a more significant reduction in spotting was observed in the levonorgestrel intrauterine system group than in the hysteroscopic niche resection group (9 months, 89.2% vs 72.1%; relative risk, 1.24 [95% confidence interval, 1.08-1.42]; 12 months, 90.2% vs 70.2%; relative risk, 1.29 [95% confidence interval, 1.12-1.48]). Moreover, compared with the hysteroscopic niche resection group, the levonorgestrel intrauterine system group had significantly fewer postmenstrual spotting days and total bleeding days from 6 months onward (all P<.001), and less pelvic pain from 3 months onward (all P<.010). No intervention-related complications were reported in any group. During follow-up, 11 (10.8%) women reported hormone-related side effects, and 2 women (2.0%) in the levonorgestrel intrauterine system group had spontaneous partial expulsion. Meanwhile, 3 unintended pregnancies were reported in the hysteroscopic niche resection group. CONCLUSION In women with niche-related postmenstrual spotting, the levonorgestrel intrauterine system was not more effective than hysteroscopic niche resection in reducing the number of spotting days by at least 50% at 6 months. However, the levonorgestrel intrauterine system was superior in reducing spotting from 9 months onward, and it reduced the absolute number of spotting days from 6 months onward and pelvic pain from 3 months onward.

Abstract
Background Cesarean scar defects (CSD) are caused by cesarean sections and cause various symptoms. Although there has been no previous consensus on the name of this condition for a long time, it has been named cesarean scar disorder (CSDi). Methods This review summarizes the definition, prevalence, and etiology of CSD, as well as the pathophysiology and treatment of CSDi. We focused on surgical therapy and examined the effects and procedures of laparoscopy, hysteroscopy, and transvaginal surgery. Main findings The definition of CSD was proposed as an anechoic lesion with a depth of at least 2 mm because of the varied prevalence, owing to the lack of consensus. CSD incidence depends on the number of times, procedure, and situation of cesarean sections. Histopathological findings in CSD are fibrosis and adenomyosis, and chronic inflammation in the uterine and pelvic cavities decreases fertility in women with CSDi. Although the surgical procedures are not standardized, laparoscopic, hysteroscopic, and transvaginal surgeries are effective. Conclusion The cause and pathology of CSDi are becoming clear. However, there is variability in the prevalence and treatment strategies. Therefore, it is necessary to conduct further studies using the same definitions.

Abstract
Levonorgestrel-releasing intrauterine devices have been used for contraception and treatment of heavy menstrual bleeding. There is only limited data about the effect of this on isthmocele. Here, we aimed to evaluate the effect of levonorgestrel-releasing intrauterine devices in a larger study population with a longer follow-up as compared to the literature on symptomatic patients with isthmocele. A total of 29 patients with symptomatic isthmocele and inserted levonorgestrel-releasing device were included in this prospective study. All patients were included at January 2020 and followed for 18 months. Sociodemographic findings, laboratory parameters, premenstrual spotting, postmenstrual spotting, menorrhagia, dysmenorrhea, and pelvic pain related to isthmocele were recorded. In sonography, width, length, area of isthmocele, and residual myometrial thickness were determined. The frequency of symptoms during follow-up was compared between visits and also compared between groups according to residual myometrial thickness. Premenstrual spotting and pelvic pain were significantly reduced at 6th months (48.3 to 10.3%, p = 0.007 and 34.5 to 10.3%, p = 0.039, respectively) and no significant change was detected until the end of follow-up period. Postmenstrual spotting reduced at 6th months (96.6 to 34.5%, p < 0.001) and also significant change was detected between 6 and 12th months (34.5% vs 13.8%, p = 0.031). Menorrhagia and dysmenorrhea disappeared at 12th months. No association was found between residual myometrial thickness and the frequency of symptoms for each follow-up. Levonorgestrel-releasing intrauterine devices are useful and reliable therapeutic tools for symptomatic isthmocele patients who do not desire fertility, regardless of residual myometrial thickness.

Abstract
Background Caesarean section (CS) scar niche is a well recognised complication of caesarean delivery and is defined as an indentation at the site of the CS scar with a depth of at least 2mm. Objectives To review systematically the medical literature regarding the current diagnosis and management of uterine niche Materials and methods We carried out a systematic review using MeSH terms ‘niche’ OR ‘sacculation’ OR ‘caesarean scar defect’ OR ‘caesarean section scar’ OR ‘uterine defect’ OR ‘isthmocele.’ Articles included were peer-reviewed and in English language. Main outcome measures Prevalence, symptoms, diagnosis, pathophysiology and management of uterine niche. Results CS scar niche is common and, in a subgroup, produces a range of symptoms including post-menstrual bleeding, dyspareunia and subfertility. It may be linked to use of locked sutures during CS closure. Niche repair can be achieved laparoscopically or hysteroscopically and appears to improve symptoms, although solid conclusions regarding fertility outcomes cannot be drawn. Conclusions CS scar niche is associated with a range of symptoms. Repair may aid subfertile patients and those with post-menstrual spotting. The presence of a niche is probably irrelevant in the absence of symptoms. What is new? LNG-IUS and surgical repair appear to improve symptoms in those with a niche.

Abstract
AIM To evaluate the efficacy of levonorgestrel 52 mg intrauterine system for intermenstrual bleeding in patients with previous cesarean delivery scar defects (PCDSs). METHODS The medical records of 28 consecutive patients with previous cesarean delivery scar defect and intermenstrual bleeding who had undergone conservative treatment with levonorgestrel 52 mg intrauterine system were reviewed. The efficacy of treatment and frequency of adverse events were measured retrospectively. RESULTS After 1 year of treatment, 22 patients (78.6%) reported an improvement in symptoms. The mean duration of menstruation were 18 and 5 days before and after treatment, respectively. No uterine perforations or pelvic inflammatory diseases occurred during or after the insertion procedures. Eighteen (64.3%) patients did not experience any adverse events, and the patients with adverse events reported that they could be managed by adjusting their medications or observation. CONCLUSION Levonorgestrel intrauterine system may have a role in the safe and effective management of intermenstrual spotting in patients with PCDSs.

Abstract
OBJECTIVE To compare the effect of a hysteroscopic niche resection with a Levonorgestrel-releasing intrauterine device (LNG-IUD, 52 mg) on postmenstrual spotting duration in patients with a symptomatic niche in the uterine cesarean scar. STUDY DESIGN This prospective cohort study was conducted at the International Peace Maternity and Child Health Hospital, School of Medicine, Shanghai Jiaotong University, China. Patients with postmenstrual spotting symptomatic niches were allocated to hysteroscopy group or LNG-IUD group based on the shared medical decision-making approach, and were followed up for 1 year after treatment. MAIN OUTCOME MEASURES The primary outcome was reduced postmenstrual spotting days at 6th month after treatment. Secondary outcomes were effectiveness rate (proportion of patients with spotting days reduced by at least 50% from baseline), menstrual characteristics, menstruation satisfaction, direct medical costs, complications and side effects. RESULTS 78 out of the 82 eligible patients were included, 36 patients in both group finished 1-year follow-up. Reduced spotting days at the 6th month was 7 days in LNG-IUD group, significantly higher than 5 days in hysteroscopy group, P = 0.004; The effectiveness rate increased over time within 1 year after the insertion of LNG-IUD (63.89%, 83.33%, 88.89%, 88.89%, P for trend = 0.006), while no trend change was observed in hysteroscopy group (71.05%, 71.05%, 66.67%, 61.11%, P for trend = 0.77). The mean direct medical costs were 817[785,856] $ in the hysteroscopy group and 243[239,255] $ in the LNG-IUD group (p<0.001). 2 patients removed IUD and 2 patients reported weight gain of more than 5 kg and breast distended pain in LNG-IUD group; 2 patients got pregnant in hysteroscopy group. No serious complications were observed in both groups. CONCLUSIONS LNG-IUD is more effective in the treatment of postmenstrual spotting from the 6th month onwards than a hysteroscopic niche resection in patients with a symptomatic niche at lower direct costs.

Abstract
INTRODUCTION Recently, the rate of caesarean sections (CS) worldwide has risen and CS-associated complications such as niche have increased substantially. Until now, evidence-based clinical guidelines for the treatment of niche-related symptoms remain absent. In patients with postmenstrual spotting, it has not been studied if the effect of levonorgestrel 52 mg intrauterine system (LNG-IUS 52 mg) is superior to that of hysteroscopy. This study will answer the question of whether LNG-IUS 52 mg is more effective in improving postmenstrual spotting than hysteroscopic niche resection in women with niche-related spotting at 6 months after randomisation. METHODS AND ANALYSIS This is a randomised controlled trial. A total of 208 women with postmenstrual spotting related to niche in the caesarean uterine scar of at least 2 mm and residual myometrium of at least 2.2 mm evaluated by MRI will be included. Women desiring to conceive within 1 year, with contraindications for LNG-IUS 52 mg or hysteroscopic surgery will be excluded. After informed consent is obtained, eligible women will be randomly allocated to LNG-IUS 52 mg or hysteroscopic niche resection at 1:1. The primary outcome is the efficacy in reducing postmenstrual spotting at 6 months after randomisation. The secondary outcomes include menstrual pattern, total days of blood loss per month, rate of amenorrhoea, side effects and complications.We will use a Visual Analogue Scale for chronic pelvic pain, urological symptoms and women's satisfaction (five-point Likert scale). ETHICS AND DISSEMINATION The study was approved by the local medical ethics committee and by the Institutional Review Board of the International Peace Maternity and Child Health Hospital, Shanghai, China (No. GKLW 2019-08). Participants will sign a written informed consent before participation. The results of this study will be submitted to a peer-reviewed journal for publication. TRIAL REGISTRATION NUMBER ChiCTR1900025677.

Abstract
OBJECTIVES To review the definitions, diagnostic methods, risk factors, symptoms, and treatments for caesarean scar niche. METHODS Review of the literature, critical reflection, and pragmatic advice. RESULTS There is no consensus on the definition of caesarean scar niche. Some suggest an indentation≥2mm of the myometrium of the caesarean scar, but this is present in more than half of women with caesarean history and takes no account of woman's symptoms. The most popular diagnostic method is ultrasound±hysterosonography. Risks factors for niche are multiple Caesareans, Cesarean during labor with too low incision, and retroverted uterus. Symptoms include abnormal gynaecologic bleeding and pelvic pain, and their presence establish the "Caesarean scar syndrome". The risks of pregnancy with niche is poorly studied, but pregnancy is not contraindicated, even if the niche is untreated. The treatment of caesarean scar niche is mainly surgery and conservative. The former should be reserved for symptomatic patients, and those with secondary infertility and fertility treatment failure. Patients with residual myometrium thickness≥2.5mm may benefit from first-line hysteroscopic treatment, whereas a laparoscopic or vaginal approach could be offered in other cases. CONCLUSIONS A pragmatic definition of caesarean scar niche as a disease including symptoms is the necessary prerequisite for the management of women. The treatment is mainly surgical, or conservative depending on the desire for subsequent pregnancy.

Abstract
Around 20% of pregnant women undergo cesarean section (CS), and in most regions of the world CS rates continue to grow. There is still no clear definition of what is considered a normal physiologic aspect of a CS scar and what is abnormal. Cesarean scar defects (CSDs) should be suspected in women presenting with spotting, dysmenorrhea, pelvic pain, or infertility and a history of CS. CSDs can be visualized with the use of hysterosalpingography, transvaginal sonography, saline infusion sonohysterography, hysteroscopy, and magnetic resonance imaging. It is reasonable to consider hormone therapy for CSDs as a symptomatic treatment in women who no longer wish to conceive and have no contraindications. In case of failure of or contraindications to medical treatment, surgery should be contemplated according to the severity of symptoms, including infertility, the desire or otherwise to preserve the uterus, the size of the CSD, and residual myometrium thickness (RMT) measurement. Hysteroscopy is considered to be more of a resection than a repair, so women who desire pregnancy should be excluded from this technique if the RMT is <3 mm, in which case repair is essential and can be achieved by only laparoscopic or vaginal approach. Women with CSDs need to be given complete information, including available literature, before any treatment decision is made. Because prevention is better than cure, risk factors should be identified early to ensure appropriate management.
