The clinical significance of small endometrial polyps

Objective

Small endometrial polyps are relatively common in asymptomatic women and may regress spontaneously. In symptomatic women, the finding of a small polyp (<1 cm diameter) raises the question of the clinical pertinence and necessity of excision. Sparse data are available on the effectiveness of hysteroscopic excision of small polyps to manage abnormal uterine bleeding. The aim of this study was to assess outcome after hysteroscopic excision of small endometrial polyps in symptomatic patients.

Study design

This was an observational cohort study enrolling 255 premenopausal women presenting with abnormal uterine bleeding and a small endometrial polyp on office hysteroscopy, undertaken between January 2004 and February 2007. The study group was referred for polypectomy by operative hysteroscopy. The outcome of the procedure was reviewed 6–12 months later by a telephone interview to assess the pattern of uterine bleeding after the procedure and overall satisfaction.

Results

Significant improvement in the magnitude of bleeding was experienced by 70% of participants, but only 30% of them reported return to regular menses. Satisfaction with the procedure was reported by 80%. Younger patients reported a less favorable bleeding pattern and were found to be less satisfied with the outcome of the procedure.

Conclusions

Symptomatic women with small endometrial polyps can be treated safely and efficiently with hysteroscopic excision. In the younger age group of patients, however, the outcome of the procedure may be less favorable and may necessitate the addition of endometrial ablation to improve outcome and increase patient satisfaction.     

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.     

Feasibility of endometrial assessment after thermal ablation

Objective

To evaluate the feasibility of endometrial assessment after endometrial thermal ablation.

Study design

Prospective observational study. A total of 57 women (age 47–52 years), who had undergone endometrial thermal ablation as a treatment for heavy menstrual bleeding (HMB) 3–10 years (mean 6 years) earlier, were examined with transvaginal ultrasound and saline sonohysterography. Endometrial samples were collected with a Pipelle device. Visualisation of endometrium, access to uterine cavity, change in cavity length, success in outpatient endometrial sampling and success in sonohysterography were evaluated.

Results

Endometrial thickness was 4.5 mm in amenorrhoeic women (n = 17), 5.6 mm in eumenorrhoeic women (n = 37) and 6.6 mm in hypermenorrhoeic women (n = 3). An endometrial sample was successfully taken in 44 (77%) women, and in 13 (23%) women endometrial sample taking failed. The length of the uterine cavity compared to the length measured before endometrial thermal ablation was 0.5–5 cm (mean 2 cm) shorter in 34 women, unchanged in four women and longer in five women. The uterine cavity distended regularly in only nine (16%) women. In 14 (25%) women the cavity distended irregularly or only partly, and in 24 (42%) women the uterine cavity did not distend at all, but appeared as a narrow tube. In 10 (18%) women the sonohysterography catheter did not enter the uterine cavity at all.

Conclusion

Endometrial assessment is compromised after previous endometrial thermal ablation. Both endometrial sampling and sonohysterography fail quite often, causing problems in diagnosis of abnormal bleeding. Intrauterine adhesions may also decrease the reliability of the endometrial sampling.     

Incidence and predictors of failed second-generation endometrial ablation

Background

The need for any treatment following an endometrial ablation is frequently cited as “failed therapy,” with the two most common secondary interventions being repeat ablation and hysterectomy. Since second-generation devices have become standard of care, no large cohort study has assessed treatment outcomes with regard to only these newer devices. We sought to determine the incidence and predictors of failed second-generation endometrial ablation, defined as the need for surgical re-intervention.We performed a retrospective cohort study at a single academic-affiliated community hospital. Subjects included women undergoing second-generation endometrial ablation for benign indications between October 2003 and March 2016. Second-generation devices utilized during the study period included the radiofrequency ablation device (RFA), hydrothermal ablation device (HTA), and the uterine balloon ablation system (UBA).

Results

Five thousand nine hundred thirty-six women underwent endometrial ablation at a single institution (3757 RFA (63.3%), 1848 HTA (31.1%), and 331 UBA (5.6%)). The primary outcome assessed was surgical re-intervention, defined as hysterectomy or repeat endometrial ablation. Of the total 927 (15.6%) women who required re-intervention, 822 (13.9%) underwent hysterectomy and 105 (1.8%) underwent repeat endometrial ablation. Women who underwent re-intervention were younger (41.6 versus 42.9 years, p?<?.001), were more often African-American (21.8% versus 16.2%, p?<?.001), and were more likely to have had a primary radiofrequency ablation procedure (hazard ratio 1.37; 95%CI 1.01 to 1.86). Older age was associated with decreased risk for treatment failure with women older than 45 years of age having the lowest risk for failure (p?<?.001). Age between 35 and 40 years conferred the highest risk of treatment failure (HR 1.59, 95% CI 1.32–1.92). Indications for re-intervention following ablation included menorrhagia (81.8%), abnormal uterine bleeding (27.8%), polyps/fibroids (18.7%), and pain (9.5%).

Conclusion

Surgical re-intervention was required in 15.6% of women who underwent second-generation endometrial ablation. Age, ethnicity, and radiofrequency ablation were significant risk factors for failed endometrial ablation, and menorrhagia was the leading indication for re-intervention.

     

El potencial maligno de los pólipos endometriales

Objectives

To determine the pre-malignant and malignant potential of endometrial polyps, and to asses whether different clinical parameters are associated with malignancy in the polyps.

Material and methods

452 hysteroscopic resections of endometrial polyps were reviewed. Histological diagnosis and clinical characteristics (presence of abnormal uterine bleeding and polyp size) were analyzed. Statistical analysis was performed.

Results

The study included 203 pre-menopausal and 249 post-menopausal women. The mean age of pre-menopausal women was 44.3 ± 0,4 years, and 59.1 ± 0.5 years for postmenopausal women. The diagnosis of polyps was by ultrasound with or without hysterosonography, or by hysteroscopy. The main indication of hysteroscopy was abnormal uterine bleeding, which was 65.1% in the pre-menopausal group and 74.7% in the post-menopausal group. There were 23 cases (11.3%) of hyperplasia without atypia in the pre-menopausal group, and 8 cases (3.2%) in the post-menopausal group. Hyperplasia with atypia was found in 2 cases (0.9%) in the pre-menopausal group, and in 9 cases (3.6%) in the post-menopausal group. There were 16 cases of endometrial carcinoma (6.4%), all of them in post-menopausal women. In 1 of these 16 patients there was no abnormal bleeding, but an endometrial polyp was suspected in the ultrasound. Menopause status was significantly associated with pre-malignant or malignant changes. No significant association was found between the presence of abnormal uterine bleeding and polyp size with pre-malignancy or malignancy in the polyp.

Conclusions

Post-menopausal women with endometrial polyp, whether symptomatic or not, should be evaluated by hysteroscopic resection. Asymptomatic pre-menopausal patients, without any risk factor, should be followed up.     

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.     

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.     

Polypectomy in premenopausal women with abnormal uterine bleeding: effectiveness of hysteroscopic removal

STUDY OBJECTIVE: To estimate the effectiveness of hysteroscopic polypectomy in premenopausal women with abnormal uterine bleeding and to identify prognostic factors for persistence or recurrence of symptoms after polypectomy. DESIGN: Retrospective study (Canadian Task Force classification II-3). SETTING: University teaching hospital. PATIENTS: Premenopausal women with abnormal uterine bleeding. INTERVENTION: Hysteroscopic polypectomy, regardless of whether combined with endometrial ablation or insertion of a levonorgestrel-releasing intrauterine device. MEASUREMENTS AND MAIN RESULTS: Seventy-eight consecutive patients met the inclusion criteria and were followed over time. Data were retrieved from medical records or from additional questionnaires sent to the patients. Failure of treatment was defined as persistence or recurrence of abnormal uterine bleeding after polypectomy, requiring further treatment. The mean age was 44.2 years (SD 5.2, 95% CI 33.9-54.4 years). Intervention-free survival after polypectomy, as calculated by Kaplan-Meier survival analysis, was 41.1% (SE 8.3%, 95% CI 24.8%-57.4%) after 4 years for patients who underwent only hysteroscopic polypectomy and 54.7% (SE 13.6%, 95% CI 28.0%-81.4%) for patients who underwent a polypectomy combined with endometrial ablation or insertion of a levonorgestrel-releasing intrauterine device (p = .08). Cox regression analyses revealed no statistically significant predictors for persistence or recurrence of symptoms after polypectomy. CONCLUSION: Nearly 60% of patients required further treatment for persistence or recurrence of abnormal uterine bleeding 4 years after hysteroscopic polypectomy. Although not significant, outcome of treatment tended to improve by combining polypectomy with either an endometrial ablation or insertion of a levonorgestrel-releasing intrauterine device.     

Histeroscopia en consulta: análisis de 5.000 pacientes

Objective

To assess the reliability, feasibility and safety of outpatient hysteroscopy.

Material and method

We performed a retrospective study of 5000 outpatient hysteroscopies performed between June 2003 and April 2008. All hysteroscopies were performed using a vaginoscopic approach and saline to distend the uterus. The indications, type of surgery, and success, failure and complication rates were analyzed.

Results

The hysteroscopies were successfully performed in nearly 97% of the patients. Severe pain and vasovagal syndrome occurred in 4% and 1.4% of the women, respectively. The most common indication was abnormal uterine bleeding and the most common diagnosis was endometrial polyps. Outpatient hysteroscopy was carried out in 60% of the patients. The most frequent type of surgery was hysteroscopic polypectomy (64%). Perforation and inflammatory disease rates were 0% and 0.08%, respectively.

Conclusions

Outpatient hysteroscopy is a well tolerated, effective and safe procedure. The combination of small-diameter hysteroscope and bipolar energy allows intrauterine disorders to be treated in the office setting without anesthesia.     

Concurrent endometrial carcinoma following hysterectomy for atypical endometrial hyperplasia

Objective

To evaluate the prevalence of concurrent endometrial carcinoma in women diagnosed with atypical endometrial hyperplasia (AEH) by endometrial biopsy.

Study design

We retrospectively analyzed the medical records of 126 patients who underwent hysterectomies for AEH diagnosed by endometrial biopsy from 1999 to 2008. AEH was initially diagnosed by dilatation and curettage (98 cases) or endometrial biopsy with a Z-sampler (24 cases). The remaining four cases were diagnosed by hysteroscopic polypectomy. The results of the endometrial biopsies were graded on an ordinal scale and were compared with pathologic features obtained at the hysterectomy.

Results

In patients preoperatively diagnosed with AEH by biopsy, hysterectomy specimens revealed a rate of simple or complex endometrial hyperplasia without atypia of 27% with AEH and normal proliferative phases found in 54.7 and 7.9% of specimens, respectively. The incidence of endometrial carcinoma was considerably high (13/126, 10.3%). Eleven of 13 cases were confined to the endometrium and the remaining two were located at the adenomyosis without myometrial invasion. All patients with endometrial carcinoma displayed coexisting atypical complex hyperplasia following hysterectomy.

Conclusions

Biopsy specimens showing AEH, particularly atypical complex hyperplasia, are associated with a risk of coexisting endometrial carcinoma. When considering management strategies for women with a biopsy diagnosis of AEH, clinicians should take into account the considerable rate of concurrent endometrial cancer and the discrepancy with pathologic diagnosis. Treatment modalities may differ depending on population as the rates of concurrent endometrial cancer with AEH and myometrial invasion vary by geographical location.     

Feasibility of hysteroscopic endometrial polypectomy using a new dual wavelengths laser system (DWLS): preliminary results of a pilot study

Purpose

Currently, endometrial polyps may be successfully treated in an outpatient setting with 5 Fr mechanical and bipolar instruments. Our aim is to evaluate the benefits of minimally invasive techniques in hysteroscopy, focusing on the use of a new dual wavelengths laser system in the treatment of endometrial polyps in an outpatient setting.

Methods

Between September 2012 and December 2014, all consecutive patients of reproductive and menopausal age with ultrasound diagnosis of endometrial polyp with maximum diameter ≤2.5 cm were eligible to participate in a prospective study. They underwent a hysteroscopic procedure with excision of the polyp using a new dual wavelengths laser system. All procedures were performed on an outpatient basis without anesthesia.

Results

Laser polypectomy was successfully performed in 219 out of 225 (97.3%). Success of surgery was not influenced by the initial location of polyp. No main complications were reported during or immediately after the procedure. 6 and 12 months follow-up with ultrasound scan did not show any persistence or recurrence of the pathology.

Conclusions

Our preliminary findings seem to support the safety and the effectiveness of the laser hysteroscopic endometrial polypectomy. However, further studies are mandatory to validate its use in daily hysteroscopic practice.

     

Laparoscopic treatment of endometrial cancer: feasibility and results

Objective

The aim of this study was to compare laparoscopic and abdominal approach in the treatment of endometrial cancer in our department.

Study design

From January 1999 to November 2002, 77 patients underwent surgery for stages I–III endometrial cancer. The first group of 36 patients had abdominal hysterectomy as well as salpingo-oophorectomy, with or without lymphadenectomy. The remaining 41 patients received laparoscopic assisted vaginal hysterectomy as well as salpingo-oophorectomy, with or without lymphadenectomy.In this retrospective study, we have compared the surgical results, the short- and long-term morbidity and the outcome of the two patient groups.

Results

Body mass index (BMI) was significantly higher in the laparoscopic group (27.3 versus 24.6; p = 0.009). The average time for surgery was significantly longer for the laparoscopic group (143.6 min versus 109.7 min; p = 0.0001), but lymphadenectomy was performed in more patients (63.4% versus 25%; p = 0.001).Postoperative hospital stay was significantly longer in patients undergoing the abdominal approach (4.59 days versus 3.18 days; p < 0.0001). No blood transfusions were performed and the rates of complications were similar in the two groups. No differences were found in recurrence and survival rate.

Conclusions

In our experience, laparoscopic and abdominal surgery can achieve similar results in the treatment of endometrial cancer. In our series, even with the BMI and the number of lymphadenectomies being higher in the laparoscopic group, the rates of complications were similar in the two groups.     

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.     

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.     

Polycystic ovary syndrome and increased polyp numbers as risk factors for malignant transformation of endometrial polyps in premenopausal women

Objective

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 of premenopausal women.

Methods

The clinical records of operative office hysteroscopic and resectoscopic procedures for endometrial polyps in 417 premenopausal women who attended Baskent University were examined over a retrospective period of 30 months. Only premenopausal patients were included in the study.

Results

In 97.8% of women, histology showed benign endometrial pathology. In 2.2% of women, pre-malignant or malignant conditions were found in the polyp. Polycystic ovary syndrome (PCOS) and the presence of 2 or more polyps were associated with significant pre-malignant or malignant changes.

Conclusion

The presence of irregular vaginal bleeding was not a predictor of malignancy in the polyp. Premenopausal women with PCOS and those with 2 or more polyps had an increased prevalence of polyp malignancy. These groups of patients, whether symptomatic or not, should be evaluated by hysteroscopic resection of the polyps.     

Laparoscopic uterine nerve ablation versus vaginal uterosacral ligament resection in postmenopausal women with intractable midline chronic pelvic pain: a randomized study

Objective

To assess and compare the laparoscopic uterine nerve ablation (LUNA) and the vaginal uterosacral ligament resection (VUSR) in postmenopausal women with chronic pelvic pain (CPP).

Study design

Eighty postmenopausal women with intractable and severe midline CPP were randomized to undergo LUNA or VUSR. Costs of two surgical procedures were assesses. Cure rate, severity of CPP, and deep dyspareunia were also evaluated after 6 and 12 months from surgery.

Results

The mean cost of LUNA resulted significantly higher in comparison with VURS (2078 ± 637 versus 1497 ± 297, P < 0.001). The cure rate was not significantly different between the two groups at 6 (33/40, 82.5% versus 35/40, 87.5% for groups A and B, respectively; P = 0.530; RR 0.94, 95% CI 0.78–1.13), and 12 months (27/36, 75.0% versus 28/38, 73.7%, for groups A and B, respectively; P = 0.901; RR 0.90, 95% CI 0.78–1.33) of follow-up. At same times, a significant (P < 0.01) decrease in severity of CPP and deep dyspareunia was observed in both groups with no difference between them.

Conclusions

Both LUNA and VUSR are equally effective surgical treatments in postmenopausal women with central CPP but VUNR is significantly cheaper than LUNA.     

Tracer injection sites and combinations for sentinel lymph node detection in patients with endometrial cancer

Objective

The aim of the present study was to clarify the most effective combination of injected tracer types and injection sites in order to detect sentinel lymph nodes (SLNs) in early endometrial cancer.

Patients and methods

The study included 100 consecutive patients with endometrial cancer treated at Tohoku University Hospital between June 2001 and December 2012. The procedure for SLN identification entailed either radioisotope (RI) injection into the endometrium during hysteroscopy (55 cases) or direct RI injection into the uterine cervix (45 cases). A combination of blue dye injected into the uterine cervix or uterine body intraoperatively in addition to preoperative RI injection occurred in 69 of 100 cases. All detected SLNs were recorded according to the individual tracer and the resultant staging from this method was compared to the final pathology of lymph node metastases including para-aortic nodes.

Results

SLN detection rate was highest (96%) by cervical RI injection; however, no SLNs were detected in para-aortic area. Para-aortic SLNs were detected only by hysteroscopic RI injection (56%). All cases with pelvic lymph node metastases were detected by pelvic SLN biopsy. Isolated positive para-aortic lymph nodes were detected in 3 patients. Bilateral SLN detection rate was high (96%; 26 of 27 cases) by cervical RI injection combined with dye.

Conclusion

RI injection into the uterine cervix is highly sensitive in detection of SLN metastasis in early stage endometrial cancer. It is a useful and safe modality when combined with blue dye injection into the uterine body.
