Narrow-band imaging offers a shorter menstrual bleeding time and a longer remission for hysteroscopic surgery in symptomatic post-cesarean scar diverticulum compared to white light

Background Narrow-band imaging (NBI) is a novel endoscopic imaging technology that improves the visibility of capillaries. The aim of this study was to evaluate the efficacy of NBI hysteroscopic excision in symptomatic post-cesarean scar diverticulum (PCSD) patients compared to conventional white light (WL) hysteroscopy. Method A total of 73 patients with symptomatic PCSD between January 2014 and December 2018 were enrolled. The enrolled patients were stratified into NBI and WL groups according to whether they received NBI or WL hysteroscopy. Postoperative menstrual patterns at one, six, and 12 months after the operation were collected and compared between the NBI and WL groups. Results A total of 32 patients underwent NBI hysteroscopy (NBI group), while 41 patients received WL hysteroscopy (WL group). The symptom-free remission rates in the NBI group were significantly higher than in the WL group at six months and 12 months post-hysteroscopy. At the final follow-up, the menstrual bleeding duration in the NBI group was significantly shorter than in the WL group. Conclusion The use of NBI hysteroscopy in treating symptomatic PCSD resulted in shorter menstrual bleeding days and longer symptomatic remission compared to conventional WL hysteroscopy.

Comparison of the anesthetic effects of remimazolam tosilate and remimazolam besylate in daytime hysteroscopic surgery

ObjectiveThe purpose of this study is to observe whether there is a difference in the anesthetic effect of remimazolam tosilate and remimazolam besylate in daytime hysteroscopic surgery, so as to provide reference for clinical application.MethodsFifty patients, aged 18–65 years, ASA I-II, scheduled for hysteroscopy under total intravenous anesthesia were selected. The patients were randomly divided into two groups (n = 25): remimazolam tosilate group (group T) and remimazolam besylate group ( group R). The main observation index was the induction dose of remimazolam; secondary observation indicators were sleep time, anesthesia maintenance time, recovery time, induction maintenance dose of alfentanil, maintenance dose of remimazolam, and incidence of adverse events during anesthesia ( hypertension, hypotension, bradycardia, tachycardia).ResultsThere was no significant difference in anesthesia induction dose, recovery time, sleep time, anesthesia maintenance time, and incidence of adverse events during anesthesia ( body movement, cough, hypertension, hypotension, bradycardia, tachycardia) between the two groups (P > 0.05).ConclusionThere was no significant difference in the anesthetic effect of remimazolam tosilate and remimazolam besylate in daytime hysteroscopic surgery.Clinical trial RegistrationChinese Clinical Trial Registry, ChiCTR2400081688.

Surgical treatment of cesarean scar pregnancy based on the three-category system: a retrospective analysis

BackgroundCesarean scar pregnancy (CSP), a distinct form of ectopic pregnancy, presents challenges in effective management. It is categorized into three subtypes according to the location of placental implantation and the thickness of the myometrium at the uterine scar. Nevertheless, the optimal choice of treatment modalities for these subtypes remains largely unexamined.MethodsIn this retrospective analysis, we investigated the cases of 130 patients diagnosed with CSP who underwent diverse treatment approaches, namely ultrasound-guided dilation and curettage (D&C), hysteroscopic surgery alone or in combination with laparoscopic surgery (HCoLC), or uterine artery embolization (UAE) followed by curettage. Clinical data were meticulously retrieved from medical records and follow-up data, and a comparative analysis of relevant indicators was carried out across the different CSP subtypes.ResultsFrom January 2017 to December 2021, 35 patients underwent D&C, 85 underwent HCoLC, and 10 received UAE as a pretreatment. In the D&C group, the success rates for Type I and Type II CSP were 64.29% (18/28) and 14.28% (1/7), respectively. Significant differences were observed between the success and failure groups in terms of gestational sac size and clinical classification. Compared to Type I CSP, Type II CSP exhibited significantly longer surgical durations and higher hospitalization costs (P < 0.05). Three patients classified as Type III underwent simultaneous hysteroscopic evacuation of cesarean scar pregnancy and laparoscopic repair of the cesarean scar defect, achieving a 100% success rate in their initial treatment. HCoLC showed no significant differences in surgical duration and hospitalization costs but had higher success rates and shorter hospital stays compared to the D&C and UAE groups (P < 0.05). The UAE group had significantly longer surgical durations, higher hospitalization costs, and a higher incidence of postoperative complications (P < 0.05). However, these factors did not result in improved surgical success rates.ConclusionThe classification of CSP and the measurement of gestational sac are of crucial importance in determining the most appropriate surgical intervention strategy. For patients diagnosed with Type I CSP, D&C and hysteroscopy are reliable treatment choices. In cases with larger gestational sacs or Type II CSP, hysteroscopy, either alone or in combination with laparoscopy, is regarded as a reliable and effective treatment approach. In patients with type III CSP, lesion excision with uterine repair is the recommended treatment.

Cervical angiofibroma of soft tissue: A rare case report with literature review.

Angiofibroma of soft tissue (AFST) is a rare benign fibrous tumor recently included in the 2020 WHO classification of soft tissue and bone tumors. Currently, there are limited reports on AFST, and pathologists lack sufficient understanding of its clinical and pathological characteristics. There is scarce literature available on AFST in the cervical region. We presented a case of a 49-year-old woman who was admitted to our hospital for emergency treatment due to vaginal bleeding and fatigue. Ultrasound revealed a 63 × 27 mm hypoechoic mass extending from the cervical opening to the external opening, with a hemoglobin level of 58.0 g/L on blood routine. The tissue exhibited a pale-yellow mucinous appearance with distinct tissue boundaries and a fibrous capsule under a microscope. HE staining revealed spindle-shaped fibroblast-like cells with a consistent morphology, thin-walled branching small blood vessels, and dilated blood vessels. Regions with abundant cells and areas with sparse cells were alternately distributed and migrated gradually. Immunohistochemical analysis indicated positive expression of P53, desmin, progesterone receptor, estrogen receptor, epithelial membrane antigen, vimentin, CD68, CD163 in the tumor, but negative expression of P16, S-100, smooth muscle actin, CD117, CD10, STAT-6. CD34 was negative in the tumor cells but positive in the vascular endothelium. The Ki-67 index value was 5%. Pathological examination confirmed a soft tissue angiofibroma of the cervix. Emergency hysteroscopic surgery was performed following infusion of 3 units of packed red blood cells. A local excision of the cervical mass was performed. A 1-month follow-up ultrasound showed no abnormal mass in the cervical canal, and there have been no signs of recurrence to date. Cervical angiofibroma of soft tissue is a rare tumor with a benign clinical manifestation, minimal local recurrence, and no significant metastatic potential. Treatment primarily involves local resection with a focus on achieving negative surgical margins. By presenting this case, we aim to enhance the diagnostic and differential diagnostic capabilities of pathologists in identifying uterine tumors and preventing misdiagnosis.

Incidence and risks of excessive distension absorption in hysteroscopic surgery using 5% mannitol solution: a retrospective descriptive study

ObjectiveTo clarify the incidence of excessive distension absorption in hysteroscopic surgery using 5% mannitol solution, evaluate the associated risks, and help to establish a safe fluid deficit threshold for such complication.DesignRetrospective descriptive study.SettingAcademic medical center.PatientsTen thousand six hundred ninety-three patients underwent inpatient hysteroscopic surgery with 5% mannitol perfusion using a monopolar electrosurgical instrument from Jan. 2015 to Sep. 2020.Intervention(s)None. This study has been approved by the Ethics Committee of Sun Yat-sen Memorial Hospital.Measurements and main resultsA fluid deficit of more than 1000 mL was defined as the diagnostic criteria for excessive distension absorption. The overall incidence of excessive distension absorption in this study was 0.46% (49/10693). The incidence was 2.57% (16/623) for transcervical resection of fibroid (TCRF), 2.36% (9/381) for retained products of conception (RPOC) removal, 1.20% (6/501) for hysteroscopic uterine septum resection (HSR), 0.48% (4/828) for transcervical resection of the endometrium (TCRE), and 0.53% (14/2621) for transcervical resections of adhesion (TCRA). Excessive distension absorption could occur within seven minutes in HSR. Among the patients diagnosed with excessive distension absorption, 30.77% (12/39) exhibited signs or symptoms related to circulation overload with a fluid deficit under 2500 mL, and 10.26% (4/39) developed pulmonary edema.ConclusionExcessive distension absorption could happen in all kinds hysteroscopic surgical treatment including RPOC removal and TCRA which were rarely reported. The overall incidence of excessive distension absorption could be low. But it would be five times higher in certain procedures such as TCRF, RPOC removal and TCRA. Resection using a needle electrode in HSR and TCRA may contribute to the short time development of excessive distension absorption. 30.77% of the patients could not tolerate the fluid deficit of less than 2500 mL which was set as a threshold for isotonic distending media and presented with circulation overload related signs or symptoms.

Effect of hysteroscopic surgery on IVF/ICSI pregnancy outcomes for different cesarean scar diverticulum severity: A retrospective cohort study.

To investigate associations between hysteroscopic surgery for patients with varying cesarean scar diverticulum (CSD) severity and invitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) embryo transfer (ET) pregnancy outcomes, focusing also on the correlation between the CSD size with its severity, and pregnancy outcomes. A retrospective study was conducted on patients with CSD who underwent IVF/ICSI-ET at a university-based hospital between January 2017 and July 2023. Patients were categorized into four groups based on CSD severity and whether they received hysteroscopic surgery: a mild surgical group (Group A, n = 86), a mild non-surgical group (Group B, n = 30), a moderate-to-severe surgical group (Group C, n = 173), and a moderate-to-severe non-surgical group (Group D, n = 96). Baseline characteristics and pregnancy outcomes were compared among these groups. Correlation assessments were conducted to explore relationships between CSD size with its severity, and pregnancy outcomes. Compared with Group D, Group C exhibited significantly increased rates of biochemical pregnancy (odds ratio [OR] 1.90; 95% confidence interval [CI] 1.03-3.51, P = 0.041), clinical pregnancy (OR 2.30; 95% CI1.18-4.45; P = 0.014), and live birth (OR 2.77; 95% CI 1.10-7.00, P = 0.031). However, no differences in pregnancy outcomes were observed between Groups A and B. Correlation analyses revealed significant positive associations between CSD severity and its depth, length, width, and volume. Patients with moderate-to-severe CSD achieved favorable IVF/ICSI pregnancy outcomes following hysteroscopic surgery. The CSD size was significantly related to its severity.

Analysis of the Predictive Factors for Chronic Endometritis Recurrence in Infertile Women.

To identify the predictive factors for the recurrence of chronic endometritis (CE) in infertile women. In this case-control study, 1170 infertile women recovered from CE and underwent fertility treatment between December 2018 and August 2021. Among the 146 women (12.5%) who did not conceive or experienced pregnancy loss in 18 months after CE recovery, 105 consecutive women who underwent repeat endometrial biopsy for CD138 immunostaining and endometrial bacterial culturing were recruited. Thereafter, patients with and without CE recurrence were compared. The total recurrence rate of CE was 29.5% (31 women). Multivariable logistic regression analysis to determine predictive factors for CE recurrence revealed that hysteroscopic surgery (odds ratio [OR], 0.10; 95% confidence interval [CI], 0.02-0.56; p=0.0009) and pregnancy loss (OR, 4.13; 95% CI, 1.31-13.05; p=0.016) were significantly associated with decreased and increased CE recurrence rates, respectively. Also, reexamination with CD138 immunostaining after 16-18 months (OR, 9.75; 95% CI, 1.47-64.64; p=0.024) was significantly associated with increased CE recurrence rates. Among 49 patients without a history of pregnancy loss, the cumulative CE recurrence rates after 6, 12, and 18 months were 5.6%, 13.5%, and 20.4%, respectively. We recommend reexamination with endometrial CD138 immunostaining in patients with pregnancy loss or long-term infertility during fertility treatment. Hysteroscopic surgery without antibiotic therapy for CE associated with intrauterine abnormalities is also recommended.

Hysteroscopic Treatment of Retained Products of Conception Using See and Treat Operative Office Hysteroscopy Without Anesthesia

Study ObjectiveTo evaluate clinical efficacy of office operative hysteroscopic treatment of retained products of conception (RPOC) without anesthesia. DesignA retrospective cohort study. SettingA tertiary care academic medical center between April 2019 to March 2023. PatientsA total of 175 patients with confirmed RPOC underwent see-and-treat operative office hysteroscopy without anesthesia in our outpatient clinic. InterventionsHysteroscopic removal of RPOC without anesthesia. Measurements and Main ResultsIn 163 cases, the removal of RPOC in the office was attempted, and in 155 cases (95.1%), complete removal of the RPOC, without complications was achieved, although it sometimes required a second procedure in clinic. In 12 cases, office operative hysteroscopy was not attempted, due to physician decision based on the appearance and vascularity of RPOC, or due to pain during the diagnostic hysteroscopy, or both.The average size of RPOC for patients treated in the clinic was 15± 8.4 mm (range 4-47mm).One hundred twenty-eight cases were performed using a Truclear Elite 6mm device, and 35 cases using a mini-Bettocchi 4.2mm device.Eighteen cases were unsuccessful on the first attempt; 12 underwent a second procedure in the clinic, which was completed in 10 (83.3%) cases.105 (71.4%) patients attended a follow-up hysteroscopy, eight of them (7.6%) required separation of adhesions that was performed in the clinic, and 8 patients were referred to a surgical procedure under anesthesia, due to persistent RPOC. ConclusionOperative office hysteroscopy is feasible and highly effective for patients with RPOC, with a total success rate of 95.1% complete evacuation in clinic. A follow-up hysteroscopy is important especially after treatment of large RPOC.

A multi-center study on the use of lidocaine thermogel for pain control in outpatient operative hysteroscopy

ObjectivesThis study aimed to explore the use of an anesthetic lidocaine thermogel in outpatient operative hysteroscopies. Specifically, it assessed the safety, tolerability, and ease of use of the gel, as well as its potential for pain reduction during the procedure. Study designThis was a multicenter observational study conducted in 9 gynecological units between March 2023 and January 2024. The study included adult women scheduled for outpatient operative hysteroscopies, excluding those with hypersensitivity to the product or recent participation in other clinical studies. The target sample size was 60 to account for potential dropouts. Data collection was electronic, and SPSS was used for analysis. The study assessed visibility conditions, procedure duration, pain scores at different stages of the procedure, and adverse event frequency. Statistical analyses utilized descriptive statistics, Student’s t-tests, Wilcoxon and Friedman tests, and Chi-Square or Fisher tests as appropriate. Binary logistic regression was applied to identify factors influencing gel volume. ResultsAll 60 participants met the inclusion criteria. The mean age was 45.5 (SD 8.8) years, with a mean BMI of 27.0 (SD 5.6) kg/m2. Medical histories were reported in 46.7% of participants, and 50% had undergone previous gynecological surgeries. Prior to the procedure, 51.8% of participants took analgesics. The average procedure duration was 13.9 (SD 15.1) minutes. Pain scores were collected at different stages of the procedure, with median VAS scores ranging from 0 to 5 out of 10. In 50% of cases, the quality of vision during the procedure was rated 9 or higher on a 10-point scale. The full recommended dose of thermogel was administered in 91.7% of cases. The mean gel volume used was 7.0 (SD 1.9) milliliters. Regression analysis showed that younger age and a history of abortions or childbirth were significantly associated with higher gel volume use. ConclusionsThe anesthetic thermogel demonstrated effectiveness in managing pain during outpatient operative hysteroscopies, with median pain scores ranging from 0 to 5 out of 10 across different stages of the procedure. The gel showed a favorable safety profile, with only 15% of participants reporting adverse effects, all of which were minor and resolved satisfactorily. The high rate of complete gel application (91.7% of cases) and positive physician feedback suggest good tolerability and ease of use. Further research is recommended to evaluate the gel’s efficacy in other gynecological procedures and to optimize application protocols based on patient-specific factors such as age and reproductive history.

Emergent Hysteroscopic Removal of Retained Products of Conception Following Laparoscopic Temporary Uterine Artery Ligation

Abstract Here, we describe two cases of retained products of conception (RPOC) that were successfully managed with hysteroscopic resection after laparoscopic temporary uterine artery ligation. Both patients were diagnosed with RPOC after early miscarriages. Case 1 was urgently admitted due to massive bleeding and underwent surgery following a blood transfusion. After laparoscopic temporary bilateral uterine artery ligation, the mass was hysteroscopically removed, and the ligation was subsequently released. The patient subsequently achieved an ongoing pregnancy. Case 2 underwent semi-emergency surgery due to intermittent bleeding. Initially, hysteroscopic surgery was planned. However, bleeding resulted in poor visualization of the operative field, and laparoscopic surgery was performed. In many previous reports of RPOC with heavy bleeding, uterine artery embolization was performed. However, there are concerns regarding the effect of a long-term reduction in uterine blood flow on fertility. Our method is not expected to decrease fertility because the ischemic effect is very short.

Telemedicine for Preoperative Assessment, Surgical Appointments, and Preoperative Education in Gynecological Day Surgery: An Prospective Observational Analysis.

This study investigates the differences in the cost, time, pre-operative education and patient satisfaction levels of patients requiring a second hysteroscopic surgery using a full-service model of remote preoperative assessment, surgical appointments, and preoperative education. Forty-one patients who were proficient in the use of telemedicine platforms, planned to undergo a second hysteroscopic surgery, and selected either telemedicine (N=21) or face-to-face (N=20) models for their preoperative assessments, surgical appointments, and preoperative education were included. The data were analyzed using the Mann-Whitney U-test and Fisher's exact test. No significant demographic differences were observed between patients who used telemedicine and those who did not. The telemedicine group demonstrated significantly lower median travel time (40 min vs 205 min, P < 0.01), time spent in hospital (60 min vs 155 min, P < 0.01), meal time (0 min vs 60 min, P < 0.01), and total time spent (108 min vs 415 min, P < 0.01). Similarly, the telemedicine group had significantly lower median travel expenses (40 yuan vs 300 yuan, P < 0.01) and meal expenses (0 yuan vs 135 yuan, P < 0.01), and overall, total expenses (255 yuan vs 837 yuan, P < 0.01). 95.2% of the telemedicine group completely understood the preoperative education, compared to 100% who completely understood in the face-to-face group (P = 1.00). All patients in the telemedicine group were very satisfied compared to 80% in the face-to-face group (P = 1.00). Telemedicine may be a feasible and advantageous method for preoperative assessment, surgical appointments, and preoperative education in gynecological day surgery. The application of telemedicine has demonstrated notable time and cost efficiency with high patient satisfaction levels. Future research should explore the full potential of telemedicine in this setting and for other surgical procedures.

High-intensity Focused Ultrasound Ablation Combined with Hysteroscopy for the Treatment of Uterine Arteriovenous Fistula Associated with Retained Products of Conception: A Prospective Cohort Study

To evaluate the efficacy of combining high-intensity focused ultrasound (HIFU) ablation with hysteroscopic removal of retained products of conception in the presence of a uterine arteriovenous fistula (UAVF). Prospective cohort study SETTING: Tertiary hospital. 17 patients with UAVF and retained products of conception. HIFU ablation combined with hysteroscopic removal of retained products of conception RESULTS: All patients presented with irregular vaginal bleeding following pregnancy termination and not responsive to medical treatment. Patients were confirmed to have a UAVF along with concurrent intrauterine residue using three-dimensional color Doppler ultrasonography, uterine angiography, or pelvic-enhanced magnetic resonance imaging; and demonstrated a poor response to medical treatment. Under real-time ultrasound guidance, HIFU was used to ablate the arteriovenous malformation region. Patients underwent hysteroscopic removal of retained products of conception; the removed tissue was subjected to pathological examination. All patients underwent monthly uterine color Doppler ultrasound examinations and menstrual status follow-up within 3 months postoperatively and showed normal menstrual recovery without signs of arteriovenous malformations on ultrasonography. Pathological examination of the tissues removed during hysteroscopic clearance revealed characteristics consistent with pregnancy, with abnormal blood vessels in some tissues. All patients experienced normal menstrual recovery postoperatively, without intrauterine adhesions. Combining HIFU ablation with postoperative hysteroscopic surgery effectively treats pregnancy related UAVF with minimal complications, preserves fertility; it offers an additional treatment option for patients wanting future fertility.

Hysteroscopic Management of Complete Vaginal and Uterine Septum with Double Cervix: Tips & Tricks for a Safe Surgery

The septate uterus is the most common uterine abnormality, comprising 35% of all identified uterine malformations. According to the ESHRE/ESGE 2013 classification, the class U2bC2V1 is a rare congenital malformation characterized by a complete septate uterus with double cervix and nonobstructive longitudinal vaginal septum. to share the decision-making process, the preoperative ultrasonographic assessment and our step-by-step hysteroscopic surgery technique to manage this complex malformation: including how to access the septate uterine cavity, the resection of the septum and its post-operative management. The goal of the surgical treatment is to restore the regular morphology of the vaginal canal and the uterine cavity with the right amount of myometrium. we present video footage of a hysteroscopic approach at a tertiary care academic medical center for managing a 21-year-old patient with a symptomatic uterine septum with double cervix and non-obstructive longitudinal vaginal septum. Both the Intraoperative and postoperative periods were uneventful: a complete resolution of the vaginal septum and creation of a single uterine cavity were obtained. Due to the significant anatomic variability of this condition, this type of surgery can be challenging. The goal of this video is also educational, aiming to illustrate a reproducible technique that can be utilized by younger or less experienced surgeons. In our experience, this hysteroscopic technique appears to be a valid option for patients with symptomatic Mullerian malformation or those with a history of recurrent miscarriages or unexplained infertility.
