Three-year follow-up results of polypectomy with endometrial ablation in the management of endometrial polyps associated with tamoxifen in Chinese women

Objective

The aim of this study was to investigate the role of hysteroscopic polypectomy with endometrial ablation in the management of tamoxifen-associated endometrial polyps in postmenopausal women with a more than 3-year follow-up period.

Study design

The medical records of 76 postmenopausal patients on tamoxifen who were performed hysteroscopic polypectomy with endometrial ablation were evaluated more than 3 years after the procedure with recurrence of polyps, recurrent abnormal uterine bleeding and surgical re-intervention.

Results

Average follow-up period was 74.91 ± 20.84 months. No patient underwent hysterectomy, 7 of 76 patients had a surgical re-intervention representing a total of 90.8% avoidance of additional surgery during the follow-up period, and 4 patients had a recurrent endometrial polyp representing the recurrence rate was 5.3%. 3 of 41 patients with postmenopausal bleeding had a recurrent abnormal uterine bleeding representing symptomatic relief rate is 92.7%. The treatment failed in 7 patients who requested surgical re-intervention: 4 patients requested a repeat polypectomy and ablation, 1 patient requested a repeat ablation and 2 patients requested a repeat hysteroscopy with uterine adhesion. No malignant endometrial pathological result was found.

Conclusions

For postmenopausal patients suffering from endometrial polyps associated with tamoxifen, hysteroscopic polypectomy with endometrial ablation continues to be proven as a safe and effective minimally invasive treatment method. The high rate of surgical re-intervention avoidance, great symptomatic relief and low recurrence rate are very encouraging for this technology.     

Hysteroscopic endometrial ablation as a treatment for abnormal uterine bleeding in patients with renal transplants

STUDY OBJECTIVE: To assess the effectiveness and safety of hysteroscopic endometrial ablation as a surgical management of abnormal uterine bleeding that develops in patients with renal transplants. DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: Yonsei University Medical College, Severance Hospital. PATIENTS: Sixty-two women with abnormal uterine bleeding who had undergone renal transplantation. INTERVENTION: Hysteroscopic endometrial ablation. MEASUREMENTS AND MAIN RESULTS: Fifty-four out of 62 patients (87.0%) who had undergone hysteroscopic endometrial ablation reported decreased bleeding (95% CI: 0.76 to 0.94): amenorrhea in 25 (40.3%), spotting in 19 (30.6%), and eumenorrhea in 10 (16.1%). Mean follow-up duration was 6 months. No complications related to the procedure were reported. Levonorgestrel-releasing intrauterine systems (LNG-IUSs) were inserted into eight patients who experienced continuous bleeding, five of whom showed symptomatic improvement: spotting in three (4.9%) and eumenorrhea in two (3.2%). The three patients (4.9%) in whom the LNG-IUS had no effect had hysterectomies, and the resultant pathologic findings were two cases of adenomyosis and one case of simple endometrial hyperplasia without atypia. CONCLUSION: Hysteroscopic endometrial ablation as a surgical management of abnormal uterine bleeding that develops in patients with renal transplants is an effective and safe procedure.     

Hysteroscopic polypectomy in 240 premenopausal and postmenopausal women

OBJECTIVE: To ascertain the therapeutic efficacy and safety of hysteroscopic polypectomy in 240 premenopausal and postmenopausal patients. DESIGN: Retrospective study. SETTING: Tertiary university hospital. PATIENT(S): Two hundred forty patients with intrauterine endometrial polyps, who mostly suffered from abnormal uterine bleeding and infertility. INTERVENTION(S): Hysteroscopic polypectomy using various instruments including microscissors, grasping forceps, or electrosurgery either with a monopolar probe or a resectoscope. MAIN OUTCOME MEASURE(S): Operating time, amount of glycine absorption, complications, resumption of normal menstruation, cumulative pregnancy rate, and recurrent rate of polyps after hysteroscopic surgery. RESULT(S): Resectoscopic polypectomy needed more operating time, had more glycine absorption and complications, but less recurrence than other hysteroscopic techniques. The resectoscope had a 0% recurrence rate and that grasping forceps had a 15% recurrence rate. A total of 21 (8.7%) complications occurred, but no major complications were noted. After long-term follow-up of 9 years and 2 months, those with abnormal uterine bleeding resumed normal menstruation in 93.1% and those with infertility had a cumulative pregnancy rate of 42.3%. There was no statistical difference in reproductive outcome between patients having polyps < or = 2.5 cm and >2.5 cm. CONCLUSION(S): We found hysteroscopic polypectomy to be effective, safe, minimally invasive procedure with low rate and mild complications. Restoration of reproductive ability did not depend on the size of the removed lesion. Resectoscopic surgery is more preferable to prevent recurrence of polyps.     

Treatment of dysfunctional uterine bleeding: patient preferences for endometrial ablation, a levonorgestrel-releasing intrauterine device, or hysterectomy

OBJECTIVE: To investigate patient preferences for endometrial ablation and a levonorgestrel-releasing intrauterine device (IUD) as alternatives to hysterectomy in the treatment of dysfunctional uterine bleeding. DESIGN: Comparative study based on structured interviews. SETTING: A large teaching hospital with 500 beds in the Netherlands. PATIENT(S): Ninety-six patients who were scheduled for endometrial ablation, 25 patients who were scheduled for hysterectomy, and 23 patients who were scheduled for a levonorgestrel-releasing IUD were interviewed. All of the women had dysfunctional uterine bleeding. INTERVENTION(S): Patients were asked to state their most significant complaints and their reasons for choosing a particular treatment. Subsequently, the preference for endometrial ablation and a levonorgestrel-releasing IUD as alternatives to hysterectomy was assessed during a structured interview. Women were informed about the advantages and disadvantages of all three treatment options. Patients rated their preferences according to different hypothetical success rates. The success rates after endometrial ablation and levonorgestrel-releasing IUD were varied until patients found an acceptable treatment outcome. MAIN OUTCOME MEASURE(S): Patient preference of endometrial ablation and the levonorgestrel-releasing IUD over hysterectomy. RESULT(S): The main reason for the treatment of choice differed between the three groups. Most of the patients in the hysterectomy group wanted a definite solution to their problems, whereas patients in the levonorgestrel-releasing IUD group and in the ablation group put greater emphasis on a minimally invasive intervention with or without a short hospital stay. In women undergoing ablation, 70% of the patients preferred this treatment and the levonorgestrel-releasing IUD to hysterectomy in cases in which the success rate of noninvasive treatment was presumed to be 50%. In women having a levonorgestrel-releasing IUD inserted, 95% of the patients preferred this approach over hysterectomy in cases in which the success rate of this device was presumed to be 50%, whereas 35% of patients preferred ablation over hysterectomy in cases in which the success rate of ablation was presumed to be 50%. In women undergoing hysterectomy, 30% would have opted for ablation and 45% would have opted for a levonorgestrel-releasing IUD in cases in which success rates were 50%. Of patients who opted for hysterectomy, however, 60% stated that they would have preferred a noninvasive treatment if the success rate of this type of treatment were >80%. CONCLUSION(S): A majority of the patients who had dysfunctional uterine bleeding and who were scheduled for an endometrial ablation or a levonorgestrel-releasing IUD were inclined to take a risk of 50% likelihood of treatment failure to avoid a hysterectomy. As a consequence, research of treatment for dysfunctional uterine bleeding should focus on this 50% success level.     

Prevention of Benign Endometrial Polyp Recurrence Using a Levonorgestrel-releasing Intrauterine System in Premenopausal Patients: A Retrospective Cohort Study

Study ObjectiveTo evaluate the levonorgestrel-releasing intrauterine system (LNG-IUS) to prevent the recurrence of endometrial polyps (EPs) after hysteroscopic polypectomies in premenopausal female patients.DesignA retrospective cohort study.SettingA tertiary-care women's hospital.PatientsA total of 451 premenopausal female patients underwent hysteroscopic polypectomies between January 1, 2016, and December 31, 2017.InterventionsTreatment with LNG-IUS after hysteroscopic polypectomies.Measurements and Main ResultsAfter the hysteroscopic polypectomies and placement of LNG-IUS, transvaginal ultrasounds were performed every 6 months to measure the recurrence of EPs. Overall, 5 (3.47%) of 144 patients in the LNG-IUS cohort and 49 (15.96%) of 307 patients in the control cohort experienced EP recurrence within the follow-up period of up to 3 years. The recurrence exhibited a strongly negative correlation when LNG-IUS was inserted (relative risk, 0.218; 95% confidence interval, 0.089–0.535; p <.05), but this did not significantly correlate with age, polyp size, number of polyps, previous history of polypectomy, and abnormal uterine bleeding. For the LNG-IUS and control cohorts, the recurrence in the first postoperative year was 1.39% and 6.19%, respectively, and 5.41% and 19.23% in the second postoperative year, respectively.ConclusionLNG-IUS reduces the recurrence of postoperative EPs in premenopausal patients.     

Treatment of endometrial polyps

OBJECTIVE: To determine the effectiveness of different treatments for abnormal uterine bleeding in women with known endometrial polyps. METHODS: We retrospectively assessed the effectiveness of polypectomy and other treatments of women with abnormal uterine bleeding who had benign polyps detected by sonohysterography. Women with endometrial polyps diagnosed by sonohysterography between January 1997 and July 1998 were sent questionnaires on pretreatment and posttreatment uterine bleeding and satisfaction with their treatments. Charts were reviewed to validate questionnaire responses and determine treatments administered. RESULTS: Seventy-eight women had endometrial polyps by sonohysterography, and 60 of them (77%) responded to the questionnaire. Two with endometrial adenocarcinoma were excluded. The average age of the remaining 58 was 49 years; 37 (64%) were premenopausal and 21 (36%) postmenopausal. The average time from treatment to follow-up was 13 months (range 5-24 months). Participants were grouped according to the following treatments: polypectomy, polypectomy plus endometrial ablation, polypectomy plus hysteroscopic myomectomy, hysterectomy, D&C, and nonsurgical treatment. The most frequent treatment was polypectomy (n = 26). Polypectomy, polypectomy plus endometrial ablation, polypectomy plus myomectomy, and hysterectomy each resulted in at least a twofold decrease in the number of bleeding days per month and led to high satisfaction rates. CONCLUSION: Our results showed that simple polypectomy and more invasive surgical procedures led to subjective improvement in symptoms of menorrhagia and metrorrhagia and a high satisfaction rate in women with endometrial polyps.     

Long-Term Outcomes After Intrauterine Morcellation vs Hysteroscopic Resection of Endometrial Polyps

Study ObjectiveTo compare the long-term outcomes of intrauterine morcellation (IUM) of endometrial polyps vs a traditional operative polypectomy technique, hysteroscopic resection (HSR), and to identify factors predictive of recurrent abnormal uterine bleeding (AUB) after operative polypectomy.DesignRetrospective cohort study (Canadian Task Force classification II-2).SettingMinimally invasive gynecologic surgery practice in a tertiary care center.PatientsWomen who underwent operative hysteroscopic polypectomy between January 1, 2004 and December 31, 2009.InterventionsIntrauterine morcellation or HSR with evaluation and/or treatment of recurrent AUB after operative polypectomy.Measurements and Main ResultsOf 311 patients (IUM group, 139; HSR group, 172), 167 (53.7%) had at least 1 gynecologic follow-up visit and 57 (18.4%) had recurrent AUB. Subsequent gynecologic clinic visit rates were similar between the 2 groups (HSR, 58.1%, vs IUM, 48.2%; p = .08). Recurrence of AUB within the first 4 years of follow-up was similar between the IUM and HSR groups (hazard ratio for HSR vs IUM, 1.12; 95% confidence interval, 0.64–1.98; p = .59). However, recurrence of endometrial polyps approached statistical significance (hazard ratio, 3.3; 95% confidence interval, 0.94–11.49; p = .06). Premenopausal status, history of hormone replacement therapy, multiparity, and polycystic ovarian syndrome were independently associated with AUB recurrence. There were no reports of inability to establish a histopathologic diagnosis among all pathology specimens evaluated.ConclusionCompared with HSR, intrauterine morcellation may be associated with lower recurrence of endometrial polyps. However, the incidence of recurrent AUB is independent of polypectomy method.     

Dysfunctional uterine bleeding: advances in diagnosis and treatment

Dysfunctional uterine bleeding occurs during the reproductive years unrelated to structural uterine abnormalities. Ovulatory dysfunctional uterine bleeding occurs secondary to defects in local endometrial hemostasis; while anovulatory dysfunctional uterine bleeding is a systemic disorder, occurring secondary to endocrinologic, neurochemical, or pharmacologic mechanisms. Evaluation of patients with abnormal uterine bleeding and identifying those with dysfunctional uterine bleeding is achieved with a combination of the following: history; physical examination; and judicious use of laboratory evaluation, endometrial sampling and uterine imaging, with sonographic techniques and/or hysteroscopy. Coagulopathies should be considered as should the notion that intramural and subserosal myomas are unlikely to contribute to AUB. High-quality evidence suggests that medical therapy is frequently successful, and newer approaches, such as local delivery of progestins via intrauterine devices, appear to be particularly promising and devoid of systemic side effects. For those intolerant of medical therapy, and/or for whom fertility is no longer desired, a number of minimally invasive surgical options for hysterectomy now exist and are collectively termed endometrial ablation. Endometrial ablation may be performed with or without hysteroscopic guidance. There is an increasing body of evidence that suggests that nonhysteroscopic endometrial ablation may be at least as effective as hysteroscopic endometrial ablation, even when the hysteroscopic procedure is performed by experts.

目的：探讨子宫内膜非典型息肉样腺肌瘤（atypical polypoid adenomyoma,APA）患者的诊治方法。方法：回顾性分析2006年1月-2015年6月首都医科大学附属复兴医院收治的24例APA患者的临床特点、诊治情况及预后,总结经验指导治疗。17例（70.8%）患者临床表现为阴道异常出血,1例（4.2%）阴道排液,3例（12.5%）超声提示宫腔占位,3例（12.5%）原发性不孕。24例患者均行宫腔镜手术,术后病理确诊。结果：24例均经病理明确诊断。宫腔镜检查和阴道彩色超声检查子宫内膜息肉及子宫黏膜下肌瘤的检出率分别为61.1%、68.4%和11.1%、15.8%,差异均无统计学意义（P＞0.05）。手术时间5～40 min,平均为（23.7±8.6）min,术中出血5～20 mL,平均为（6.5±2.9）mL。术后随访1～10年,失访4例。3例患者宫腔镜子宫内膜息肉电切术后行全子宫切除术,术后随访无异常。1例3个月后复查仍为APA,再次宫腔镜手术,术后肌注促性腺激素释放激素激动剂（GnRHa）,复查病理正常后宫腔放置左炔诺孕酮宫内缓释系统,至今随访2年无异常。1例术后8年因子宫内膜上皮内瘤变行子宫切除术,余15例至今随访无异常;2例不孕患者术后妊娠并足月分娩。结论：宫腔镜电切术作为APA的一种有效的治疗方式,具有定位准确、手术创伤小、复发率低的优点,但因有病变复发及恶变可能,术后仍应密切随访。 【关键词】     

Pregnancy rates after hysteroscopic polypectomy depending on the size or number of the polyps

Objective To assess the reproductive benefits of hysteroscopic polypectomy in previous infertile women depending on the size or number of the polyps. Design and methods In this retrospective study, from February 2000 to September 2005, totally 83 selected women were included with: a) diagnoses of primary or secondary infertility, endometrial polyp/polyps and abnormal uterine bleeding. Endometrial polyps were diagnosed by transvaginal ultrasound followed by diagnostic hysteroscopy, to confirm diagnosis, and hysteroscopic polypectomy. All 83 subjects who consisted the study group, met inclusion criteria: age under 35 years, at least 12 months of infertility, from 3 to 8 months menstrual disorders (intermenstrual bleeding or spotting, menometrorrhagia or menorrhagia) and from 3 to 18 months of follow-up with attempts to conceive after hysteroscopic polypectomy. The endometrial polyp/polyps appeared to be the only reason to explain their infertility after infertility workup of the couples. There was a comparison of fertility rates after hysteroscopic polypectomy between patients having endometrial polyp ≤ 1 cm and patients with bigger or multiple polyps. Results Of the 83 subjects, all were found to have endometrial polyps in diagnostic hysteroscopy, confirmed at histologic examination after hysteroscopic polypectomy. Among patients of the study group, there were no significant differences in age, type or length of infertility, or follow-up period after the procedure. The mean size of the endometrial polyps was 1.9 ± 1.4.cm. Thirty-one patients had endometrial polyp ≤ 1 cm and 52 patients had bigger or multiple endometrial polyps. Following polypectomy, menstrual pattern was normalized in 91.6% of patients. Spontaneous pregnancy and delivery at term rates, in the total population of the study, increased after the procedure and were 61.4% and 54.2% respectively. There was no statistical difference in fertility rates between patients having polyps ≤ 1 cm and patients having >1 cm polyps or multiple polyps. Spontaneous abortion rate in the first trimester of pregnancy was 6% of the total number of patients and there was no statistical difference between patients with small or bigger/multiple polyps. Type of infertility did not affect fertility rates after hysteroscopic polypectomy. Complication rate after hysteroscopic polypectomy was as low as 2.4%, while recurrence rate of the procedure reached 4.9% of patients. Conclusion Hysteroscopic polypectomy of endometrial polyps appeared to improve fertility and increase pregnancy rates in previous infertile women with no other reason to explain their infertility, irrespective of the size or number of the polyps. Type of infertility of patients seems not to affect fertility rates after hysteroscopic polypectomy. Menstrual pattern was normalized in the majority of patients after hysteroscopic polypectomy. In addition, hysteroscopic polypectomy is a safe procedure with low complication rate.     

Levonorgestrel-releasing intrauterine system in the treatment of dysfunctional uterine bleeding: A French multicenter study

OBJECTIVE: To evaluate the levonorgestrel-releasing intra-uterine system as an alternative to surgical treatment in patients presenting with menorrhagia. PATIENTS AND METHODS: In the set of a prospective multicenter study, 49 patients with menorrhagia resistant to medical treatment and/or referred for hysterectomy or endometrial ablation were included. Medical visits were organized 3, 6, 12, 24 and 36 months after insertion of the levonorgestrel-releasing intra-uterine system. Visual score of menstrual bleeding and satisfaction index were noted on each visit. Transvaginal ultrasound, pap smear, endometrial biopsy, and clinical data were retrieved one month before and 12 months after inclusion for tolerance evaluation. RESULTS: Renouncement rate was 90.0% (95% CI = 80.7-96.6%). After a twelve months follow-up, 86.1% of patients were satisfied or very satisfied with their clinical state. We found a significant increase of hemoglobin rates from baseline (14,0 versus 12,9 g/dl; P < 10(-4)). Similar increases were also found in serum iron and ferritin. DISCUSSION AND CONCLUSION: This study confirms the efficacy of the levonorgestrel-releasing intra-uterine system in the control and reduction of menstrual blood loss in patients with dysfunctional uterine bleeding. The high rate of surgery cancellation is a proof of the potential role of the levonorgestrel-releasing intra-uterine system as an alternative treatment in these patients.     

Endometrial cancer following endometrial resection

Endometrial ablation has emerged as a viable alternative to hysterectomy in the treatment of medically intractable dysfunctional uterine bleeding. However, this procedure cannot guarantee complete removal of the entire endometrium. Cases of endometrial cancer after endometrial ablation have been reported in the literature. We reviewed the cases of patients who underwent hysteroscopic endometrial ablation by endometrial resection for abnormal uterine bleeding from 1994 to 2005 at the Department of Obstetrics and Gynecology, Polyclinique, Clermont-Ferrand University. Of the 3769 patients having had hysteroresections, four developed endometrial cancer after complete endometrial ablation (1.06 out of 1000). All four of these patients showed histological evidence of endometrial polyps at endometrial resection, and all of them presented risk factors for endometrial carcinoma, such as obesity and/or arterial hypertension. Endometrial cancer after hysteroscopic endometrial ablation is a rare but possible occurrence, even a long time after the operation. Close monitoring of patients who have undergone endometrial ablation for endometrial polyps and who present risk factors, such as obesity or hypertension, even after apparent total ablation of the endometrium is strongly recommended, independently of the presence of abnormal bleeding that can represent a late symptom of advanced endometrial cancer.     

Endouterine Eingriffe – Abrasio, Hysteroskopie und Endometriumablation

Uterine bleeding disorders may cause diagnostic intrauterine interventions such as hysteroscopy and curettage or therapeutic procedures such as hysteroscopic polypectomy, myomectomy, or endometrial ablation. Hysteroscopic myoma resection has excellent results, as the bleeding pathology is directly correlated with the submucous location of uterine leiomyomata. Endometrial ablation is an established procedure; nevertheless, it is still not performed often in German-speaking countries. The long-term results of three prospective randomized trials comparing endometrial ablation with hysterectomy show a decrease in the advantages of endometrial ablation over time. Currently, several new techniques for endometrial ablation are under investigation, which are standardized, easy to perform, and avoid the hysterocopic mode of access.     

Frequency of symptomatic cornual hematometra and postablation tubal sterilization syndrome after total rollerball endometrial ablation: a 10-year follow-up

OBJECTIVE: This study was undertaken to determine the frequency of symptomatic cornual hematometra and postablation tubal sterilization syndrome after total rollerball endometrial ablation and to describe methods for diagnosis, treatment, and prevention. STUDY DESIGN: Retrospective cases of 50 consecutive patients who received total rollerball endometrial ablation for dysfunctional uterine bleeding were followed up for 10 years. RESULTS: Symptomatic cornual hematometra or postablation tubal sterilization syndrome was diagnosed by ultrasound scanning and/or magnetic resonance imaging in 5 of 50 patients (10%) who had a total endometrial ablation. Two patients had cornual hematometra, and 3 patients had postablation tubal sterilization syndrome 4 months to 90 months after rollerball ablation. Subsequent gonadotropin-releasing hormone agonist treatment or hysteroscopic decompression of the hematometra was only partially successful, and recurrence of symptoms necessitated hysterectomy with salpingectomy. CONCLUSION: Uterine contracture, which obstructs bleeding from persistent cornual endometrium and leads to symptomatic cornual hematometra or postablation tubal sterilization syndrome, is not uncommon after total rollerball endometrial ablation, with an incidence of 10% in our series. Satisfactory treatment requires hysterectomy with salpingectomy, but modifications such as partial endometrial ablation can prevent these complications.     

Découvertes hystéroscopiques chez les femmes de 40 ans et moins avec saignement utérin anormal

Objective: describe hysteroscopic findings among women of 40 years old or less with abnormal uterine bleeding.Methods: this is a retrospective cohort study, using hospital and clinic files for the period of January 1988 to April 1997, where 191 patients 40 years old or younger had a diagnostic hysteroscopy for abnormal uterine bleeding. The rate of successful hysteroscopies, the type of anaesthesia, and hysteroscopic complications were listed. Type and frequency of intrauterine pathology, such as endometrial polyps, submucous myomas, hyperplasia and atrophy, were analyzed. Particular attention was devoted to the incidence of pathology which were not identified by endometrial biopsy (polyps and submucous myomas. Prior treatment before hysteroscopy was also assessed.Results: hysteroscopy was successfully completed in 95.8 percent of cases and the majority of the procedures 67.5% were done under local anaesthesia (paracervical block). No perforation or other major complication has been listed. Intrauterine pathology was diagnosed in 24 percent of patients and, among them, 9.8 percent had an endometrial polyp and 6.6 percent had a submucous myoma. About half of patients 45.9% had no treatment prior to hysteroscopy. Among those with previous treatments, 41 percent failed to respond to oral contraceptive therapy: in those patients, 13.3 percent had an endometrial polyp and 8.0 percent had a submucous myoma.Conclusion: hysteroscopy is a useful diagnostic approach for the investigation of patients 40 years old or less with abnormal uterine bleeding. In 24 percent of these patients, hysteroscopy enables the detection of intrauterine lesions. Most of which could not be detected by endometrial biopsy. According to this retrospective study, it seems preferable to recommend a diagnostic hysteroscopy rather than an endometrial biopsy for the investigation of abnormal uterine bleeding among women 40 years old or younger.     

Hysteroscopic resection of endometrial polyps: a study of 195 cases

OBJECTIVE: To ascertain the therapeutic efficiency of hysteroscopic resection for the treatment of endometrial polyps in women with abnormal uterine bleeding and postmenopausal metrorrhagia. SETTING: University hospital. DESIGN: Retrospective consecutive patient follow-up. MATERIAL AND METHODS: From 1987 to 1997, 195 patients with haemorrhagic endometrial polyps were treated with hysteroscopic resection in our department. RESULTS: Five complications occurred, but no major complications were noted. A total of 89.2% of the patients remained in contact after hospitalization. After long term follow-up (5.2 years), successful results were obtained in 80% of the patients with polyp resection without associated endometrial ablation. Further surgery (hysterectomy) was required in only five women. CONCLUSION: Transcervical resection is the gold standard for treatment of endometrial polyps.     

Utilidad de la histeroscopia en el manejo del sangrado uterino anormal

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.     

The impact of alternative treatment for abnormal uterine bleeding on hysterectomy rates in a tertiary referral center

Study ObjectiveThe purpose of this study was to estimate the influence of alternatives to hysterectomy for abnormal uterine bleeding (AUB) on hysterectomy rates.DesignRetrospective cohort study. Canadian Task Force II-2.SettingUniversity hospital.PatientsPremenopausal patients with AUB.InterventionsMedical records of all premenopausal patients treated for AUB in our university clinic between January 1, 1995, and December 31, 2004, were reviewed. Patients were identified based on (specific) diagnostic and therapy codes used in the registry system of the hospital. The total number of placements of levonorgestrel-releasing intrauterine device (LNG-IUD), hysteroscopic surgery, and hysterectomies performed/year was estimated. In addition, the course of treatment of each patient was assessed.Measurements and Main ResultsA total of 640 patients received surgery and 246 LNG-IUDs were placed. The proportion of endometrial ablations decreased significantly over time (p <.001), whereas hysteroscopic polyp or myoma removal (p =.030) and insertion of LNG-IUD (p <.001) both increased. The proportion of patients receiving hysterectomy for AUB as their first therapy decreased significantly (p =.005) from 40.6% to 31.4%, although the total number of patients receiving hysterectomy remained similar (p =.449). The 5-year intervention-free percentage for LNG-IUD was 70.6% (SD = 3.3%), for hysteroscopic polyp or myoma removal 75.5% (SD = 3.3%), and for endometrial ablation 78.0% (SD = 4.3%; p =.067).ConclusionDespite the introduction of alternative therapies, the total hysterectomy rate in the management of AUB did not decrease in our clinic.     

Post-Ablation Cavity Evaluation: A Prospective Multicenter Observational Clinical Study to Evaluate Hysteroscopic Access to the Uterine Cavity 4 Years after Water Vapor Endometrial Ablation for the Treatment of Heavy Menstrual Bleeding

Study ObjectivePatients who have undergone endometrial ablation may present a diagnostic challenge when they subsequently develop vaginal bleeding, pelvic pain, or postmenopausal bleeding. Extensive scarring of the uterine cavity often precludes evaluation and/or conservative treatment. For further research on this topic, we performed hysteroscopic examination in study subjects a mean duration of 4 years after they had undergone water vapor endometrial ablation.DesignProspective, multicenter, observational clinical study.SettingEight private practice or outpatient sites in the United States and Mexico.PatientsSeventy subjects who had completed their 36-month follow-up in the AEGEA Pivotal Trial.InterventionsDiagnostic hysteroscopy.Measurements and Main ResultsThe subjects were screened for general health and infection and underwent diagnostic hysteroscopy. Menstrual bleeding status was recorded. The video of the hysteroscopic examination was analyzed by an independent reviewer, who assessed uterine cavity access and visualization of the cornua and tubal ostia as well as characterized adhesions on the basis of the criteria by March et al. An independent reviewer also subjectively assessed whether Pipelle endometrial biopsy or intrauterine device placement would be feasible. Uterine cavity access was achieved in 90% (63/70) of subjects. Among subjects with cavity access, the cornua and ostia were visualized in 79% (50/63) and adhesions were absent in 75% (47/63), with only 2 women having severe adhesions (3%, 2/63). Biopsy was projected to be feasible in 86% (62/70) and intrauterine device placement in 60% (42/70) of all subjects. The subjects’ bleeding statuses were not correlated with uterine cavity access. The results were consistent for subjects with large uterine cavities and International Federation of Gynecologic and Obstetrics type II to VI myomas ≤4 cm.ConclusionWater vapor endometrial ablation preserved an accessible uterine cavity and visualization of the ostia in most subjects, with minimal incidence of severe adhesions, a mean of 4 years after the ablation procedure.     

Reoperative hysteroscopic surgery in the management of patients who fail endometrial ablation and resection

STUDY OBJECTIVE: To determine the safety and efficacy of reoperative hysteroscopic surgery for women who fail endometrial ablation and resection. DESIGN: Retrospective chart review and follow-up (Canadian Task Force classification II-2). SETTING: Private office practice. PATIENTS: Twenty-six women who had undergone endometrial ablation or resection and experienced failure characterized by intolerable pain, bleeding, or asymptomatic hematometra. INTERVENTION: Sonographically guided hysteroscopic endomyometrial resection. MEASUREMENTS AND MAIN RESULTS: Mean length of time from initial treatment for abnormal uterine bleeding and reoperative hysteroscopic surgery was 41.2 +/- 47.9 months. Five (19.2%) women required simple dilatation and 21 (80.8%) required endocervical resection to achieve access to the uterine cavity. There were no operative complications. Mean operating time was 20.3 +/- 9.5 minutes. Mean specimen weight was 6.7 +/- 4.9 g. Adenomyosis was present in 15 (57.7%) specimens. Women were followed for a mean of 23.2 +/- 22.7 months. Twenty-three (88.5%) achieved satisfactory results and avoided hysterectomy. Three women (11.5%) eventually required hysterectomy because of recurrent pain or bleeding. CONCLUSION: Reoperative hysteroscopy is useful in managing women after failed endometrial ablation and resection. It produces excellent results in achieving amenorrhea and relief of cyclic pelvic pain, thereby avoiding hysterectomy in most patients.
