Utilidad de la histeroscopia en el manejo del sangrado uterino anorma / Usefulness of hysteroscopy in the management of abnormal uterine bleeding

La histeroscopia se considera actualmente la prueba que posibilita no solo el diagnóstico, sino también el tratamiento de enfermedad intrauterina en paciente con clínica de sangrado uterino anormal causado por anomalías estructurales, como pólipos, adenomiosis, miomas submucosos, hiperplasia endometrial o cáncer de endometrio. La miniaturización del diámetro de los histeroscopios con canal de trabajo, del minirresector bipolar y de los sistemas de morcelación histeroscópica han permitido el tratamiento en régimen ambulatorio, en ocasiones en el mismo tiempo que el diagnóstico histeroscópico, aportando mayor satisfacción, reducción riesgos quirúrgicos o derivados de la anestesia y posibilitando una rápida resolución coste-efectiva de los síntomas. En este artículo se revisa la utilidad de la histeroscopia para el diagnóstico y el tratamiento de la enfermedad estructural intrauterina causante de sangrado uterino anormal.(AU)

Hysteroscopy is currently considered the test that enables not only the diagnosis but also the treatment of intrauterine pathology in patients with symptoms of abnormal uterine bleeding caused by structural abnormalities such as polyps, adenomyosis, submucosal fibroids, endometrial hyperplasia, or endometrial cancer. The miniaturization of the diameter of hysteroscopes with working channels, the bipolar mini-resector, and the hysteroscopic morcellation systems have allowed outpatient treatment, sometimes at the same time as hysteroscopic diagnosis, providing greater satisfaction, reducing surgical and/or anaesthesia risks and enabling rapid cost-effective resolution of symptoms. This article reviews the usefulness of hysteroscopy for the diagnosis and treatment of intrauterine structural pathology causing abnormal uterine bleeding.(AU)

Importance of abdominal X-ray to confirm the position of levonorgestrel-releasing intrauterine system: A case report.

BACKGROUND: Levonorgestrel-releasing intrauterine systems (LNG-IUSs) gradually release levonorgestrel into the uterus and is effective against hypermenorrhoea and dysmenorrhea. Complications associated with the insertion include expulsion, displacement, and uterine perforation. Ultrasonic identification of copper intrauterine devices (IUDs) is possible due to echogenicity from the copper coils. However, the barium sulfate coatings of LNG-IUSs do not always provide hyperechoic images. Both barium sulfate and copper are radiopaque and clearly identifiable on X-ray. Thus, X-ray imaging is required to locate LNG-IUSs. CASE SUMMARY: A 46-year-old woman with hypermenorrhoea due to submucosal myomas was treated with LNG-IUS at another hospital. Three LNG-IUS insertions had apparently been followed by spontaneous expulsion, although objective confirmation using imaging was not performed. The patient was referred to our institution for surgery. At the first visit, there appeared to be no device in the uterus, and none was observed on transvaginal ultrasound. However, two LNG-IUSs were observed in the pelvis on abdominal plain X-rays prior to surgery. Hysteroscopic myomectomy was performed, and the two LNG-IUSs were found to have perforated the myometrium. The devices were safely removed during surgery, and the submucosal myomas were also removed. The perforated section of the myometrium was minimal+ADs- therefore, a repair operation was not required.CONCLUSIONPlain abdominal X-rays facilitate the determination of whether an LNG-IUS is in the uterine cavity. Therefore, it is important to confirm a device's location, regardless of whether spontaneous expulsion is suspected, prior to inserting another device.

Case Report: Gastric-Type Endocervical Adenocarcinoma Mimicking Submucosal Myoma Under Hysteroscopy.

Gastric-type endocervical adenocarcinoma (GAS) is considered a distinct and clinically important entity because it is unrelated to human papillomavirus infection and has aggressive behavior and worse clinical outcomes than the usual type of endocervical adenocarcinoma (ECA). The preoperative diagnosis of GAS is often difficult because of its nonspecific clinical manifestations and special lesion location. We report the case of a 50-year-old Chinese woman who presented with intermittent left lower abdominal pain for 1 year. Preoperative images showed left hydrosalpinx and a lesion that was mainly located in the lower part of the uterine cavity. We considered the lesion to be a polyp before surgery. During hysteroscopic surgery, we suspected that it may be a submucosal myoma. However, pathology revealed that it was a GAS. GAS may be located in the upper endocervix or even reach the uterine cavity. The appearance is occasionally similar to that of submucosal myoma, resulting in difficult preoperative diagnosis and even misdiagnosis.

The Blooming phenomenon: a rarity, but a dilemma in hysteroscopic resection of myomas

Modern surgical technologies allow gynecologists to treat most submucosal myomas hysteroscopically by some form of resection. What appears on imaging or direct visualization to be a submucosal myoma can be a single tumor, or may represent multiple smaller myomas appearing as one, compacted together in a typical pseudo capsule. During myoma resection, the effect of the media used to induce distension can vary, depending on the morphology of the myomas. After starting resection, the pressure of the distending media can push truly solitary myomas to somewhat flatten against the uterine wall. However, in the second type of myoma, the fluid can displace the myomas into the uterine cavity, an appearance similar to the blooming of a flower. The tip of the hysteroscope may enter the dissected spaces between the myomas, which impairs the panoramic view. This phenomenon may cause inadequate treatment of the myomas encountered during hysteroscopic myomectomy. In this study, the "Blooming phenomenon" is introduced, and the problems created by this phenomenon and solutions for its management are considered.

Clinical application of three-dimensional transvaginal ultrasonography in the diagnosis of intrauterine adhesions.

OBJECTIVE: The present study aimed to evaluate the diagnostic accuracy of three-dimensional transvaginal ultrasonography (3D-TVS) for intrauterine adhesions (IUA). METHODS: We performed a retrospective cohort study. A total of 500 women aged 19 to 46 years with uterine lesions who received treatment from the Department of Obstetrics and Gynecology were enrolled. Endometrial 3D imaging was conducted to obtain the display plane and 3D-TVS parameters. Patients also underwent hysteroscopy for a definitive diagnosis. RESULTS: For diagnosing IUA, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall accuracy of 3D-TVS were 98.8%, 90.8%, 91.4%, 98.7%, and 94.8%, respectively. For diagnosing a submucosal myoma, the sensitivity, specificity, PPV, NPV, and overall accuracy of 3D-TVS were 88.2%, 97.9%, 88.2%, 97.9%, and 96.4%, respectively. For diagnosing endometrial polyps, the sensitivity, specificity, PPV, NPV, and overall accuracy of 3D-TVS were 94.7%, 96.8%, 92.9%, 97.7%, and 96.2%, respectively. CONCLUSIONS: Before hysteroscopy, 3D-TVS, as a method of screening, has great value for comparing differences before and after treatment, and for evaluating therapeutic effects.

Combined treatment for big submucosal myoma with High Intensity Focused Ultrasound and hysteroscopic resection.

OBJECTIVE: Big submucosal myoma often causes heavy menstrual bleeding and are complicated in hysterscopic surgery. High Intensity Focused Ultrasound (HIFU), is a method for myoma ablation therapy, which may benefit on size reduction, and assist following hysterscopic myomectomy. CASE REPORT: Two cases, case one,. 44-year-old female with 3.8 cm submucosal myoma, STEPW (Size, Topography, Extension, Penetration and Wall) score 6 and case 2. 48-year-old female, with 6.0 cm submucosal myoma, STEPW score 8, both received HIFU treatment before hysterscopic myomectomy was done. The myomas reduced after 5 months with improvement of anemia. The following hysterscopic myomectomy shows less operative time and fewer blood loss. CONCLUSION: HIFU reduce size of submucosal myoma and may improve anemia after months. Less operating time and blood loss were demonstrated in the following hysterscopic myomectomy. For well selected patients, combined treatment with HIFU and hysteroscopic resection may decrease complication rate.

Clinical application of Lin's biopsy grasper for intrauterine targeted biopsy and polypectomy during office hysteroscopy.

OBJECTIVE: Hysteroscopy has widely been used for diagnosis of the uterine cavity; however, target biopsy has often been difficult in part to the inherent limitations of ancillary instruments. Lin's biopsy grasper was specifically designed to work in conjunction with a flexible hysteroscope to obtain intrauterine biopsy under transabdominal sonography. Herein, we share our clinical experience in the management of endometrial abnormalities with the use of Lin's biopsy grasper during office-based hysteroscopy. MATERIALS AND METHODS: From February 2006 to November 2016, the use of Lin's biopsy grasper for tissue biopsy was attempted on 126 cases. We retrospectively recorded and analyzed the patients' preoperative characteristics and biopsy outcomes to demonstrate the feasibility and efficacy of Lin's biopsy grasper. RESULTS: Out of the one hundred and twenty-six enrolled patients, satisfactory targeted biopsies were achieved; including high diagnostic rate (92.1%, with 116 cases confirmed histologically) and adequate tissue retrieval (77.8%, with 98 cases obtaining optimal specimen volume). All patients tolerated the procedure without analgesics or anesthesia. CONCLUSION: Diagnostic flexible hysteroscopy combined with the use of Lin's biopsy grasper has proven to be an effective tool for intrauterine evaluation and obtaining tissue sample.

Analysis of features and differential diagnosis of ultrasonic image for endometrial lesions / 中国医学装备

Objective:To investigate the analysis of features and differential diagnosis of ultrasonic image for patient with endometrial lesions.Methods: The imaging data of 80 patients with endometrial lesions were selected as random number table. The relevant ultrasound manifestations and sonographic features of patients were further analyzed, and then these data were compared with the pathological diagnosis by using operation.Results: In the 80 patients with endometrial lesions, 43 cases were endometrial polyps, and in the 43 cases, there were 41 cases were consistent with the pathological diagnosis and the diagnostic accordance rate was 95.35%, while there were 2 cases were not consistent between the two methods. 33 cases of the 80 patients were submucous myoma of uterus, and there were 29 cases of them were consistent with the pathological diagnosis and the diagnostic accordance rate was 87.88%, while there were 4 cases were not inconformity. And 4 cases of the 80 patients were endometrial carcinoma, the result was completely consistent with the pathological diagnosis and the diagnostic accordance rate was 100%. In the 6 misdiagnose cases, the ratios of atypical cases and (or) typical cases were 1:16, 5:36 and 1:8, respectively. All of these endometrial lesions has the distinctive manifestations on the ultrasonoscopy of color Doppler.Conclusion: For the detection of endometrial lesions, transvaginal colar Doppler ultrasonic detection has unique feature of ultrasonogram compared with other detection methods. In the contrast, there is a regular congruent relationship between the ultrasonogram of typical disease and section of pathological specimen by using operation in a certain degree, and the ultrasonogram of typical disease has definite diagnosis value.

A Rare Case of Intra-Endometrial Leiomyoma of Uterus Simulating Degenerated Submucosal Leiomyoma Accompanied by a Large Sertoli-Leydig Cell Tumor.

A 50-year-old peri-menopausal woman presented with hard palpable mass on her lower abdomen and anemia from heavy menstrual bleeding. Ultrasonography showed a 13×12 cm sized hypoechoic solid mass in pelvis and a 2.5×2 cm hypoechoic cystic mass in uterine endometrium. Abdomino-pelvic computed tomography revealed a hypodense pelvic mass without enhancement, suggesting a leiomyoma of intraligamentary type or sex cord tumor of right ovary with submucosal myoma of uterus. Laparoscopy revealed a large Sertoli-Leydig cell tumor of right ovary with a very rare entity of intra-endometrial uterine leiomyoma accompanied by adenomyosis. The final diagnosis of ovarian sex-cord tumor (Sertoli-Leydig cell), stage Ia with intra-endometrial leiomyoma with adenomyosis, was made. Considering the large size of the tumor and poorly differentiated nature, 6 cycles of chemotherapy with Taxol and Carboplatin regimen were administered. There is neither evidence of major complications nor recurrence during 20 months' follow-up.

[Fertility after hysteroscopic resection of submucosal myoma in infertile women]. / Fertilité après résection hystéroscopique de myomes sous-muqueux chez des patientes infertiles.

OBJECTIVES: Myoma is the most frequent benign uterine tumor and might have a negative impact on fertility. In 5 to 10% of cases, infertility is associated with myoma and in 1 to 3% myoma is the only infertility factor. Even if effect of myomectomy on fertility is controversial, benefit of hysteroscopic myomectomy for submucosal myoma on fertility has already been shown. The aim of this study is to evaluate fertility of infertile women less than 46years old after hysteroscopic resection of submucosal myoma. MATERIAL AND METHODS: This retrospective unicentric study took place in the gynecologic unit of a teaching hospital. All infertile women with a hysteroscopic myomectomy for submucosal myoma between March 2009 and May 2013 were included. A phone questionnaire was conducted to evaluate pregnancy rate, eventual medical assistance, time between submucisal resection and pregnancy and issue of pregnancies. RESULTS: Seventy-one infertile women with a hysteroscopic resection of submucosal myoma were included. Pregnancy rate was 33.8% with 50% of live births, 41.6% of miscarriages and 8.4% of late fetal losses with a mean follow-up of 28.7months. Mean time between hysteroscopic resection and pregnancy was 9.9months. A medical assistance was necessary for 6 women (25% of pregnancy). CONCLUSION: This study reports hysteroscopic resection of submucosal myoma for infertile women. The rate of pregnancy after treatment is 33.8%.

Outpatient multimodality management of large submucosal myomas using transvaginal radiofrequency myolysis.

STUDY OBJECTIVE: To evaluate the safety and efficacy of transvaginal radiofrequency myolysis (RFM) with or without combined hysteroscopy for treatment of large submucosal leiomyomas with a substantial intramural portion. DESIGN: Retrospective observational study (Canadian Task Force classification III). SETTING: Hospital outpatient department. PATIENTS: Twenty-four patients with large submucosal leiomyomas with a substantial intramural portion. INTERVENTIONS: Transvaginal RFM with or without combined hysteroscopy. MEASUREMENTS AND MAIN RESULTS: Twenty-four patients with large submucosal leiomyomas with a substantial intramural portion were enrolled to undergo stepwise RFM. Additional hysteroscopic myomectomy was performed in 6 patients at 3 to 6 months after RFM. Myoma volumes were measured via 3-dimensional ultrasonography before RFM and at 1, 3, 6, 12, and 24 months postoperatively. Symptom severity was assessed using the Uterine Fibroid Symptom and Quality of Life questionnaire and the Health-Related Quality of Life questionnaire. The total volume reduction rate 24 months postoperatively was 84.2%. Symptom severity and health-related quality of life scores demonstrated substantial improvements at 12 months after RFM. CONCLUSIONS: RFM with or without hysteroscopy is an effective treatment for large myomas with deep intramural positioning, and it seems safe for use in all patients with submucosal myoma-related symptoms.

Objective To explore the clinical effect of hysteroscopic resection in the treatment of submucous myoma.Methods The clinical data of 78 submucosal myoma patients with hysteroscopic resection which were diagnosed by B ultrasound and hysteroscopy were retrospectively analyzed,including 35 cases of type O,23 cases of type Ⅰ,20 cases of type Ⅱ.Results Application of hysteroscopic resection in the treatment of type O and type Ⅰ submucosal myoma,the rate of postoperative satisfaction was 100.0％.There were 3 cases of multiple myoma in 20 cases of type Ⅱ,which were not one time of resection,and were taken the second times of resection 4 months after operation.In all operation,there was on complications,and the rate of postoperative satisfaction was 96.2％.Conclusion Hysteroscopic resection in the treatment of submucous myoma for the preservation of reproductive function and not affecting ovarian function has the advantage of less bleeding,short operation time,rapid postoperative recovery,shorter hospitalization time,and greatly improve the quality of life of patients,and has good clinical application value,it provides the effective treatment for clinical,and is worthy of clinical popularization.

Clinical Analysis of Hysteroscopic Resection for Submucosal Myoma of Uterus with Dipolar Electrodes: A Report of 300 cases / 中国微创外科杂志

Objective To evaluate advantages and safety of bipolar electrodes for the treatment of submucosal myoma of uterus.Methods Three hundred patients with submucous myoma of uterus were performed with bipolar electrodes under hysteroscope,including 212 cases of type 0 submucous myoma,54 cases of type ?,and 34 cases of type Ⅱ.Results Total volumes of uterine distention fluid used during operation were 500-2000 ml(mean,626 ml);operation time was 20-50 min(mean,25 min);intraoperative blood loss was 10-20 ml.Cardio-cerebral syndrome occurred in one case and was relieved by timely treatment.There was no operation discontinuation as a consequence of pain.The diameters of resected myomas were 3-5 cm,with an average of 3.8 cm.The postoperative diagnosis showed leiomyosarcoma in 1 case and was performed by radical hysterectomy resection combined with a pelvic lymphadenectomy at 10 day postoperatively.During the follow-up period of 1-24 months in 277 cases,40 cases(type I in 12 cases;type II in 28 cases) needed hysteroscope operation again.Conclusions Hysteroscopic resection for submucosal myoma of uterus with dipolar electrodes has advantages of safety,minimal invasion,quicker recovery,higher efficiency,so it is worthy of being recommended.

Hysteroscopic evaluation of the efficacy of sonohysterography for diagnosis of submucosal myoma / 대한산부인과학회잡지

OBJECTIVE: To evaluate the efficacy of sonohysterography on exact submucosal myoma. methods: Transvaginal sonohysterography was performed on 45 patients who diagnosed as submucosal myoma and 29 patients who diagnosed as endometrial polyp by classic abdominal or vaginal sonogram, and then they received the diagnostic hysteroscopy at all. RESULTS: In 24 of 45 patients on sonohysterogram, submucosal myoma was diagnosed that was protruded to uterine cavity more than 2/3 of mass. Nine patients had intramural myoma and 12 patients had myoma that protruded only lesser than 1/3 of mass on sonohysterogram. These 21 patients revealed the same finding on hysteroscopy. On hysteroscopy, submucosal myomas were in 20 of 24 patients and polyps were in 3 patients and synechia was in one patients. In 8 of 29 patients on sonohysterogram, endometrial hyperplasia was found and confirmed by hysteroscopy. In 16 of 21 patients whose finding was polyp on sonohsyterogram, polyp was confirmed by hysteroscopy. However hysteroscopic findings were myomas in 3 of 21 patients and synechia in one patients. Therefore in 29 of 74 patients (39.2%), further hysteroscopy was not needed by sonohysterogram. In 65 of 74 patients (87.8%), sonohysterographic findings were same as hysteroscopic findings. CONCLUSION: Sonohysterogram for diagnosis of submucosal myoma and polyp is essential procedure in order to avoid unnecessary hysteroscopy. However differentiation between polyp and submucosal myoma has still some difficulty.

The Prognosis of Resectoscopic Myomectomy of Submucosal Myomas / 대한산부인과학회잡지

OBJECTIVES: To examine the outcome after operative resectoscopic resection of submucosal myomas in symptomatic women. METHODS: Forty eight symptomatic women with submucosal myomas underwent operative resectoscopy for resection of the submucosal myomas. A few months after the myomectomy, I compared postoperaive status of the patients to preoperative status of the patients. RESULTS: No operative or postoperative complications occurred and all patients were discharged within 4 days. The follow-up period was 11.12+/-6.44 months(mean+/-SD). The age of the patients was 37.69+/-9.22 years(mean+/-SD) at the time of the operation. Twelve women out of 16 conceived(pregnancy rate of 75%)and all of them subsequently delivered at term. Thirty two women(menorrhagia of 28 and backache of 4) had been rid of their chief complaints that they had suffered from preoperatively. CONCLUSION: The results of this study indicate that operative resectoscopy achieved a pregnancy rate 75%. These results suggest that operative resectoscopy is an effective procedure to resect submucosal myomas in infertile symptomatic women.

Transcervical expulsion of a submucosal myoma as a result of uterine artery embolization / 대한산부인과학회잡지

Uterine artery embolization was introduced to arrest post-partum hemorrhage 20 years ago. It has also been used to control severe hemorrhage from uterine gestational trophoblast tumors, carcinoma of the uterus, uterine arteriovenous malformations, and cases of pelvic trauma. More recently, transcatheter uterine artery embolization is a new treatment for uterine leiomyoma. A 33-year old married woman with 2 children had a history of heavy pelvic pain and pressure. Ultrasound and MRI investigation showed a bulky 12 x 10cm submucosal myoma in right lower uterine segment. The both uterine artery embolization was performed via a bilateral femoral artery. We present a case in which successful embolization of the uterine arteries in a woman with submucosal myoma resulted in a subsequent transcervical expulsion of large pieces of the dominant fibroid after 3 month of treatment with a brief review.
