Long-term results of hysteroscopic resection of endometrial polyps in 367 patients. Role of associated endometrial resection

OBJECTIVE: To assess the results of hysteroscopic resection of endometrial polyps and the eventual role of associated endometrial resection. PATIENTS AND METHODS: Retrospective study. Between 1998 and 2001, 367 patients had hysteroscopic resection of endometrial polyps, which were initially confirmed by diagnostic hysteroscopy. Fifty-four percent of these had associated endometrial resection. RESULTS: Five intraoperative complications and/or incidents were noted, but there was no major complication. 83% of patients were followed up and the median follow-up period was 40 months (range 17-66 months). The success rate in this study was 96.4%. This is higher in the group of patients that had associated endometrial resection: 98.3 vs 93.7%. DISCUSSION AND CONCLUSION: Hysteroscopic resection is the optimal method for treatment of benign endometrial polyps. Associated endometrial resection in older patients or in patients not desiring to conserve their fertility potential improves the success rate and decreases the rate of recurrences.     

Outcomes of endometrial-polyp treatment with hysteroscopy in operating room

To assess the results of using a resectoscope in the hysteroscopic resection of endometrial polyps that were previously diagnosed by office hysteroscopy and to demonstrate the necessity of extraction for histological study. A prospective long-term follow-up study (level of evidence II-2). University Hospital. 303 women presenting a hysteroscopic image of an endometrial polyp. Interventions: Office hysteroscopy, hysteroscopic resection of polyps by means of a resectoscope and an anatomopathological study of the polyps. Statistical analysis was performed. 303 diagnosed endometrial polyp formations were resected by means of hysteroscopy during surgery. In all cases, biopsies of the uterine cavity or of the polyp were negative. Resection of the polyps with hysteroscopy in the operating room using a resectoscope proved to be a safe technique. The anatomopathological study of the polyps showed hyperplasia with atypias in 10 cases (3.3%) and endometrial cancer in 9 women (3.0%). Our study data suggest that endometrial polyps should be resected because they may harbor malignant or premalignant lesions. Hysteroscopic surgery is recommended for its simplicity and scant complications.     

A randomized, prospective study of endometrial resection to prevent recurrent endometrial polyps in women with breast cancer receiving tamoxifen.

STUDY OBJECTIVE: To assess the role of endometrial resection in preventing recurrence of tamoxifen-associated endometrial polyps in women with breast cancer. DESIGN: Randomized, prospective study (Canadian Task Force classification I). SETTING: Tertiary university-affiliated medical center. PATIENTS: Twenty consecutive women (age range 43-61 yrs). INTERVENTIONS: Hysteroscopic removal of tamoxifen-associated endometrial polyps with or without simultaneous resection of the endometrium. MEASUREMENTS AND MAIN RESULTS: Patients were randomized to undergo (10 women) or not undergo (10) concomitant endometrial resection. They were followed for at least 18 months (range 18-24 mo), including transvaginal ultrasonography every 6 months and hysteroscopy when endometrial irregularity was noted. The main outcome variable was recurrence of endometrial polyps; occurrence of uterine bleeding was also noted. In women who underwent endometrial resection, only one had a 1 x 1-cm endometrial polyp diagnosed and removed during follow-up. Seven women remained amenorrheic, and three experienced spotting for a few days every month. In the control group, six women had recurrent endometrial polyps requiring hysteroscopic removal (two-tail Fisher's exact test p <0.06). CONCLUSION: Recurrence of endometrial polyps, one of the most common problems in patients with breast cancer receiving long-term treatment with tamoxifen, may be reduced by performing endometrial resection at the time of hysteroscopic removal of polyps. The possible risk of occult endometrial cancer is yet to be determined. (J Am Assoc Gynecol Laparosc 6(3):285-288, 1999)     

Long-term impact and risk factors for hysterectomy after hysteroscopic surgery for menorrhagia

The objective of this study was to assess the long-term impact of management and establish the incidence of hysterectomy, and to identify factors predictive of failure of the procedure among women who had undergone hysteroscopic endometrial resection with or without myomectomy for menorrhagia. Clinical history and data on additional treatment and follow-up status were obtained by medical record review and postal questionnaire for 279 women who had undergone hysteroscopic surgery. Follow-up data were available for 259 (93%) cases, and the mean follow-up was 6.0 years. Subsequent hysterectomy was the primary endpoint, and its incidence was calculated by survival analysis. Univariant analysis and Cox regression model were used to identify predictors of failure. Myomas, polyps, adenomyosis, or endometrial hyperplasia were found in 40.9% of hysteroscopic procedures. Perioperative complications occurred in 5.7% and late complications in 7.7%. During the follow-up period, 97 (37.5%) of 259 women underwent at least one gynecological procedure. The incidence of hysterectomy was 23.6% (95% confidence interval: 18.8–29.1%). Positive predictive factors for hysterectomy were long uterine cavity (≥9 cm) and tubal ligation. Most (82.8%) of the 198 women who did not undergo hysterectomy had postoperative oligo- or amenorrhea. Hormone replacement therapy was common (67%) among postmenopausal women after endometrial resection. Hysteroscopic resection of the endometrium and concomitant hysteroscopic resection of fibroids for the treatment of menorrhagia is a suitable alternative to hysterectomy and offers lasting results. A large uterine cavity indicating possible uterine pathology and tubal ligation associated with hematometra increase the risk of hysterectomy.     

A randomized prospective study of the use of endometrial ablation for prevention of recurrent endometrial polyps in breast cancer patients receiving tamoxifen

Objective: To assess the roles of endometrial ablation in prevention of recurrence of tamoxifen-associated endometrial polyps in breast cancer patients.Design: A randomized prospective study of tamoxifen-treated patients who underwent hysteroscopic removal of endometrial polyps with or without simultaneous resection of the endometrium.Materials and Methods: Twenty consecutive women (aged 43–61 years) undergoing hysteroscopic removal of tamoxifen-associated endometrial polyps were randomized via a computer-generated random table to undergo or not to undergo concomitant endometrial ablation. All patients had undergone endometrial sampling prior to the procedure. The patients were followed for at least 18 months (range 18–24 months). The follow-up included transvaginal ultrasonography every 6 months and hysteroscopy when endometrial irregularity was noted. The main outcome variable was recurrence of endometrial polyps while the occurrence of uterine bleeding was noted.Results: In the 10 study group women, who underwent endometrial ablation, only 1 patient had a 1 × 1 cm endometrial polyp diagnosed and removed during the follow-up period. Seven of the study women remained amenorrheic, and 3 experienced spotting a few days every month. In the control group, a recurrent endometrial polyp, necessitating hysteroscopic removal, was diagnosed postoperatively in 6 women (two-tailed Fisher’s Exact test; P < .06).Conclusion: Recurrence of endometrial polyps, one of the most common problems in breast cancer patients receiving long-term treatment with tamoxifen, can be significantly reduced by performing endometrial ablation at the time of hysteroscopic removal of the polyp. The possible risk of occult endometrial cancer is yet to be determined.     

Hysteroscopic resection of symptomatic and asymptomatic endometrial polyps

STUDY OBJECTIVE: To estimate the occurrence of malignancy and atypical hyperplasia in endometrial polyps in patients with and without symptoms. DESIGN: Retrospective registration of all patients who underwent hysteroscopic resection of endometrial polyps. Age, menopausal status, presence or absence of symptoms, any use of hormonal medication, as well as histologic diagnosis, complications, and eventual repeated surgery were documented (Canadian Task Force classification II-3). SETTING: Ullevaal University Hospital, Department of Gynecology. PATIENTS: All patients who underwent hysteroscopic resection of an endometrial polyp in our department from January 1, 2001 through March 1, 2005. INTERVENTIONS: Hysteroscopic resection of endometrial polyps. MEASUREMENTS AND MAIN RESULTS: Four hundred eleven patients were included. One hundred twenty-nine patients (31.4%) had no symptoms. The prevalence of malignancy or atypical hyperplasia was 3.2% in women with symptoms and 3.9% in those without symptoms. CONCLUSION: The prevalence of malignancy and atypical hyperplasia was found to be relatively high, indicating that symptomatic, as well as asymptomatic, endometrial polyps should be removed.

目的：探讨宫腔镜切除子宫内膜息肉（endometrial polyp,EP）的疗效及影响术后自然妊娠状态的因素。方法：选取2013年2月-2014年11月在天津市咸水沽医院妇产科宫腔镜电切治疗的60例EP合并不孕患者为研究对象。术后3、6、18个月随访患者的阴道不规则出血、EP复发率、自然妊娠率,并分析影响患者术后自然妊娠的因素。结果：术后阴道不规则出血发生率为3.33%,EP复发率为1.67%。术后3个月累积自然妊娠率为28.33%,术后6个月累积自然妊娠率为50%,术后18个月累积自然妊娠率为65.00%。单因素分析结果显示,不同年龄EP患者宫腔镜术后自然妊娠率差异有统计学意义（P＜0.01）;不同不孕年限、不孕类型及息肉大小的EP患者宫腔镜术后自然妊娠率比较差异无统计学意义（P＞0.05）。多因素分析显示,年龄＞30岁是EP患者宫腔镜切除术后自然妊娠率的影响因素（OR=11.00,95%CI：4.108~29.454,P=0.000）;原发性不孕、不孕年限＞3年、息肉＞1 cm或多发则不是EP患者术后自然妊娠率的影响因素（P＞0.05）。结论：对于EP合并不孕的患者,宫腔镜治疗具有良好的治疗效果,且患者年龄越小术后自然妊娠的成功率越高。     

Long-term results of hysteroscopic myomectomy in 235 patients

OBJECTIVE: To assess the efficacy of transcervical resection of submucous fibroids according to type and size. MATERIALS AND METHODS: Retrospective follow-up of 235 women with submucous fibroids at outpatient hysteroscopy who underwent a hysteroscopic transcervical resection. The main indications were the abnormal uterine bleeding and fertility problems. Thirty-seven percent of patients had an associated endometrial ablation and 32% had a polyp resection. Fifty-one percent of women were menopausal. In cases of incomplete resection a repeat procedure was offered. RESULTS: Intra-operative complications were rare (2.6%) and there was no major complication. Eighty-four percent of cases were followed-up. The median follow-up was 40 months (range 18-66 months). The procedure was classed as a success in 94.4% of patients. Among the cases that were classed as a failure, four patients had a repeated hysteroscopic procedure, three patients had a subsequent hysterectomy and four patients presented with abnormal uterine bleeding at follow-up. CONCLUSION: The hysteroscopic transcervical resection of submucous fibroids is a safe and highly effective long-term therapy for carefully selected women presenting with abnormal uterine bleeding and fertility problems. It produces satisfactory long-term results with few complications.     

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.     

Specific hysteroscopic findings can efficiently distinguish the differences between malignant and benign endometrial polyps

ObjectiveTo evaluate differences in hysteroscopic findings between benign endometrial polyps and endometrial cancer.Materials and methodsFrom January 2012 to December 2016, we extracted 179 cases with endometrial polyps from 3066 women who underwent hysteroscopy followed by dilatation and curettage or transcervical resection, with 154 and 25 cases of benign and malignant endometrial polyps, respectively. Clinical characteristics, histopathological and hysteroscopic findings of the women were evaluated retrospectively.ResultsThe hysteroscopic findings of malignant polyps were hyper-vascular (72%, 18/25), ulcerative (64%, 16/25) and polyps with irregular surfaces (24%, 6/25). In contrast, pedunculate small growths with smooth surfaces were usually seen in the benign endometrial polyps (38.3%, 59/154). Hyper-vascular (OR: 142.6, 95% CI: 25.98–783.4) and polyps with irregular surfaces (OR: 12.02, 95% CI: 1.765–81.83) in hysteroscopic findings were significant strong predictors of endometrial polyps with endometrial cancer. Hysteroscopic findings of ulcerative changes were most strongly associated with a diagnosis of malignant polyps, with sensitivity, specificity, negative (NPV) and positive (PPV) predictive values of 64.0%, 100%, 94.5%, and 100%, respectively.ConclusionWomen with hysteroscopic findings of endometrial polyps with hyper-vascular, ulcerative, and polyps with irregular surfaces had a high likelihood of endometrial cancer. A target biopsy of the polyps with these specific appearances should be performed to exclude malignant lesions.     

The malignant potential of endometrial polyps

OBJECTIVES: To determine the pre-malignant and malignant potential of endometrial polyps and to assess whether different clinical parameters are associated with malignancy in the polyps. STUDY DESIGN: Four hundred and thirty consecutive cases of hysteroscopic diagnosis of endometrial polyp were retrieved. The medical records, preoperative vaginal sonography results and histopathology findings were reviewed. Statistical analysis was performed. RESULTS: Hysteroscopy truly identified endometrial polyps in 95.7% of the cases. In 11.4% cases, hyperplasia without atypia was found in the endometrial polyp. In 3.3 and 3.0% of women pre-malignant or malignant conditions were found in the polyp. Older age, menopause status and polyps larger than 1.5 cm were associated with significant pre-malignant or malignant changes, although the positive predictive value for malignancy was low. All the malignant polyps were diagnosed only in postmenopausal women. The presence of postmenopausal or irregular vaginal bleeding, was not a predictor of malignancy in the polyp. CONCLUSIONS: Postmenopausal women with endometrial polyps are at increased risk of malignancy in the polyp. Those patients, whether symptomatic or not should be evaluated by hysteroscopic resection of the polyps. Asymptomatic premenopausal patients with polyps smaller than 1.5 cm can be observed.

Hysteroscopic evaluation of endometrial polyps.

OBJECTIVE: To establish the validity of hysteroscopy for predicting cancer in endometrial polyps based on their number, size and hysteroscopic appearance. METHOD: Retrospective observational study of 653 women diagnosed hysteroscopically as having endometrial polyps. After outpatient or surgical hysteroscopic resection or resection following hysterectomy, the diagnosis was confirmed by histological examination. The incidence of cancer in women who had polyps was determined in the light of menopausal status, symptoms, size, number and appearance of the polyps. RESULT: Carcinoma was found in only 3.9% of the women who consulted for menopausal metrorrhagia and were diagnosed as having a polyp. Hysteroscopy had a sensitivity of 36% and a specificity of 98% for a diagnosis of cancerous polyp or atypical hyperplasia. CONCLUSION: The appearance and number of endometrial polyps seen by hysteroscopy may be useful in predicting cancer in the polyps, although resection and histological examination will still be necessary to confirm the diagnosis.     

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.     

Hysteroscopic findings of endometrial carcinoma. Evaluation of 104 cases

PURPOSE OF INVESTIGATION: Retrospective evaluation of hysteroscopic findings in the accurate diagnosis of endometrial carcinoma. METHODS: A retrospective monocentric study from January 1995 to December 2004. One hundred and four patients with hysteroscopic aspects evocative of endometrial carcinoma confirmed by endometrial biopsy during diagnostic hysteroscopy, by surgical hysteroscopic resection pieces or by hysterectomy specimen were included. RESULTS: Among the 104 patients, diagnostic hysteroscopy pointed out endometrial features suggestive of endometrial carcinoma in 102 cases. In two women diagnostic hysteroscopy failed to diagnose endometrial malignancy which was identified on pieces of polyps by surgical hysteroscopic resection. DISCUSSION: Polypoid proliferations cerebroid in appearance, with ulceration and necrosis, friable and with irregular vessels, represent endometrial findings highly indicative of malignancy. The diagnosis may be missed in cases of focal neoplasias, within endometrial polyps or in conditions of unsatisfactory endouterine visualization.     

Resectoscopic removal of symptomatic intrauterine lesions

In order to avoid major surgical intervention in women who refused or were poor risks for hysterectomy or myomectomy, a hysteroscopic resectoscope was used for 90 women with uncontrollable uterine bleeding due to submucous fibroids or large polyps or with menorrhagia with normal endometria. Of those patients followed for more than three months, 90% of endometrial ablation patients had an improvement in menstrual flow, with 79% having scant or no periods. For patients with submucous fibroids or polyps, 91% had resumption of normal menses. For the 15 patients who were infertile and underwent submucous fibroid or polyp resection the term pregnancy rate is 33% to date. With only two complications in the series (perforation and endometritis), the conclusion is that resection of submucous lesions and endometrial ablation using the resectoscope is a safe and highly effective alternative to hysterectomy for those conditions.     

Perioperative predictors of successful hysteroscopic endometrial ablation

OBJECTIVE: To determine which perioperative factors influence the success of hysteroscopic endometrial ablation in patients with menorrhagia. STUDY DESIGN: A longitudinal study of 128 women who underwent hysteroscopic endometrial ablation or resection. Clinical data included age, uterine size, the presence of intramural or submucosal myomas and polyps, and length of follow-up from initial hysteroscopic ablation to re-ablation or hysterectomy ('failure'). Kaplan-Meier survival analysis, log-rank tests and Cox proportional hazard regression were used to evaluate the equality of survival distributions and to model the overall effects of the various predictor variables on surgical outcomes. RESULTS: Patients were followed for a median time of 44 months. Thirteen women (10.2%) underwent a second operative procedure. Multivariate analysis identified submucosal myoma as a statistically significant positive predictor of the risk of failure [hazard ratio (HR) 5.22, 95% confidence interval (CI) = 1.63, 16.73)]. Older age was associated with a marginally lower risk of subsequent surgery (HR 0.90 per additional year of age, 95% CI = 0.81, 1.00). CONCLUSIONS: The presence of submucosal myoma increases the risk of subsequent surgery in patients undergoing endometrial ablation.     

Five-year follow-up of endometrial ablation: endometrial coagulation versus endometrial resection

OBJECTIVE: A randomized, controlled trial was performed to compare the patient complication rate, effectiveness, and satisfaction rate of transcervical hysteroscopic endometrial coagulation versus endometrial resection in the treatment for heavy dysfunctional bleeding. METHODS: One hundred and twenty women requiring endometrial ablation for the treatment of heavy bleeding disorders entered the study. All patients were offered a clinical examination 24 months postoperatively and had a questionnaire by mail 5 years after the initial treatment. The number of complications during and after the operation, re-ablations, and hysterectomies were registered. A bleeding index and the patient satisfaction rate were stated. RESULTS: Sixty-one patients were treated by endometrial coagulation, and 59 were treated by endometrial resection. No differences between the two groups were observed concerning fluid absorption, bleeding, perforation, and infection. At the 5-year follow-up, 64% of the patients had only one ablation, 15% were treated twice, 15% had a hysterectomy, and 6% were lost to follow-up. After 5 years, the bleeding index was halved in patients with menses. Seventy-nine percent of the women would recommend the treatment to their best female friend. CONCLUSION: We found no significant differences in the frequency of complications. Only 15% of the women had a hysterectomy after 5 years. No significant difference was observed with respect to bleeding reduction and patient satisfaction in the two groups.     

Hysteroscopic Resection of Endometrial Polyps and Assisted Reproductive Technology Pregnancy Outcomes Compared with No Treatment: A Systematic Review

Endometrial polyps are frequently encountered in the uterine cavity of infertile women. There is much debate regarding the treatment of endometrial polyps in patients who are undergoing assisted reproductive technology (ART). A systematic review was performed by searching PubMed, Embase, and the Cochrane Library for retrospective or prospective studies that compared the effect of hysteroscopic resection of polyps with no treatment on pregnancy outcomes of patients who underwent ART. The primary outcomes were clinical pregnancy, live birth, miscarriage, and implantation rates after ART. Eight studies with a total of 2267 patients were included. The results showed that hysteroscopic resection of endometrial polyps (mean size <2 cm) was associated with an increased rate of clinical pregnancy in patients who underwent intrauterine insemination. No clear benefit was observed for clinical pregnancy, live birth, miscarriage, or implantation rates in patients who underwent in vitro fertilization/intracytoplasmic sperm injection cycles. In conclusion, the effect of hysteroscopic polypectomy on pregnancy outcomes of patients who have undergone ART remains unclear. More prospective, randomized controlled trials are warranted to determine appropriate treatment.
