Analysis of the therapeutic effects of hysteroscopic polypectomy with and without doxycycline treatment on chronic endometritis with endometrial polyps.

PROBLEM: We aimed to compare the therapeutic effects of hysteroscopic polypectomy with and without doxycycline treatment on chronic endometritis (CE) with endometrial polyps. METHOD OF STUDY: DESIGN: A cross-sectional study was conducted on 267 infertile patients, of whom 243 were recruited, who underwent hysteroscopic polypectomy between March 2019 and March 2020. During surgery, the endometrial specimens for the immunohistochemistry analysis of the plasma cell marker CD138 and for the intrauterine bacterial culture were obtained to diagnose CE, and the prevalence of CE was analyzed. Of the 222 women who were diagnosed with CE after polypectomy, we treated 62 women with doxycycline (antibiotic group) and did not provide antibiotics in 160 women (non-antibiotic group). RESULTS: Most of the infertile patients with endometrial polyps had CE (92.6%). The recovery rate from CE by hysteroscopic polypectomy was significantly higher in the non-antibiotic group than in the antibiotic group (88.8% and 58.1%, respectively, p < 0.0001). The duration of recovery from CE in the non-antibiotic group was shorter than that in the antibiotic group (42.6 ± 41.0 and 56.5 ± 32.3 days, respectively, p < 0.0001). The clinical pregnancy rate within 6 months in non-antibiotic group was higher than that in the antibiotic group (63.2% and 43.8%, respectively, p = 0.034). CONCLUSION: Endometrial polyps are significantly associated with CE. Most CE patients with endometrial polyps had been cured by polypectomy without doxycycline. Inappropriate antibiotic therapy may delay recovery from CE and decrease the efficacy of polypectomy on CE and pregnancy rates.

The Endometriosis Fertility Index Is Useful for Predicting the Ability to Conceive without Assisted Reproductive Technology Treatment after Laparoscopic Surgery, Regardless of Endometriosis.

OBJECTIVE: The endometriosis fertility index (EFI) is a novel index for predicting pregnancy after surgery. We investigated the utility of the EFI for predicting the ability to conceive without assisted reproductive technology (ART) treatment after laparoscopic surgery. METHODS: From July 2011 through December 2012, we recruited 133 infertile patients who underwent laparoscopy, and the EFI was calculated. After surgery, 55 of 133 achieved pregnancy without ART treatment. We evaluated the factors that predicted a naturally successful pregnancy and compared them between the pregnant and non-pregnant subjects. RESULTS: On a univariate linear regression analysis, we found that a younger age, shorter duration of infertility, and higher EFI were positively associated with a successful pregnancy without ART after laparoscopic surgery (p < 0.05). According to 50th percentile EFI, the cutoff EFI predicting a successful pregnancy without ART was 7, the pregnancy rate in the high-EFI group (EFI; 8-10) was significantly higher than that in the low-EFI group (EFI ≤7; p < 0.05), but the duration to natural conception after surgery was similar between the 2 groups. CONCLUSION: The EFI possesses greater predictive power for a successful pregnancy with natural intercourse or intrauterine insemination in infertile patients, regardless of endometriosis, than the Revised-American Society of Reproductive Medicine classification.

Frequency of endometrial cancer and atypical hyperplasia in infertile women undergoing hysteroscopic polypectomy.

AIM: We aimed to determine the frequency of endometrial cancer in infertile women undergoing hysteroscopic endometrial polypectomy for endometrial polyps. METHODS: A total of 1035 infertile patients who underwent office-based hysteroscopic polypectomy at Sugiyama Clinic Marunouchi between July 2011 and October 2015 were eligible for this retrospective study. All patients had been diagnosed with endometrial polyps via hysterofiberscopy prior to operation, and they underwent hysteroscopic endometrial polypectomy using a resectoscope with monopolar resection. Surgical specimens were examined histopathologically. Characteristics of patients diagnosed with endometrial cancer on histopathological examination were evaluated retrospectively. RESULTS: The median age of patients was 32 years (range, 19-44 years). On histopathological examination, endometrial cancer was found in 10 patients (0.97%). Each histological type of endometrial cancer was represented as follows: three cases of endometrioid adenocarcinoma G1; one of endometrioid adenocarcinoma G2; two of endometrioid adenocarcinoma G3; and four of atypical endometrial hyperplasia. The median age of endometrial cancer patients was 34 years (range, 28-41 years), and the median body mass index was 21.2 kg/m2 (range, 16.7-29.9 kg/m2 ). Nine endometrial cancer patients were nulliparous, and all had undergone infertility treatment, with only one woman having delivered a healthy baby. An ovulation disorder was noted in four patients, with obesity (body mass index > 25 kg/m2 ) in just two. Polycystic ovary syndrome was concomitantly observed in one patient. However, abnormal vaginal bleeding was not noted in any of these patients. CONCLUSION: Hysteroscopic polypectomy should be performed when endometrial polyps are detected on investigational screening, and surgical specimens should be checked for the presence of malignancy.

[Case of bilateral common carotid artery dissections due to localized dissection of the aortic arch].

We report a case of a 56-year-old man who had a localized dissection of the aortic arch presenting with left conjugate deviation, right homonymous hemianopsia, and right hemiparesis. Diffusion-weighted MRI revealed multiple fresh cerebral infarctions of the left cerebral hemisphere and the bilateral cerebellar hemispheres. The patient did not complain of chest pain, but thoracic computed tomography (CT) and three-dimensional CT angiography showed a localized dissection of the aortic arch at the bases of the brachiocephalic artery and left common carotid artery (CCA). He was diagnosed with embolic cerebral infarctions due to aortic dissection and treated with heparin and edaravone. However, without progressive symptoms and enlargement of the dissected aneurysm, we continued to follow the wait-and-scan policy for the aortic dissection. Neurological signs and symptoms gradually improved during his admission. The pseudolumen had yet to close and there has been no change in size and shape of the dissected aneurysm for about one year. It is necessary to carefully follow up the case and to keep in mind cerebral infarctions caused by aortic dissection.

The decrease of serum luteinizing hormone level by a gonadotropin-releasing hormone antagonist following the mild IVF stimulation protocol for IVF and its clinical outcome.

PURPOSE: While performing the mild ovarian stimulation protocol with a GnRH antagonist, the pregnancy rate was compared between the groups, which were divided by the degree that the luteinizing hormone (LH) level decreased. MATERIALS AND METHODS: Patients aged 27 to 42years (36.1 +/- 3.79) underwent 308 IVF cycles who opted for IVF via the mild ovarian stimulation protocol began clomiphene citrate on day 3 and recombinant FSH on day 5. A GnRH antagonist was administered when the dominant follicle reached 14mm. Serum LH was measured at the time of GnRH antagonist administration and at the time of hCG injection. The pregnancy rate and implantation rate were compared between 50 cycles in which the LH level dropped less than one-third and the control (LH level within 1/3). RESULT(S): The pregnancy rate for the group in which the LH level fell less than one third was 18%. Conversely, the pregnancy rate for the control group was 39%. The implantation rate was 18% for the less than one-third group and 26% for the control group. Both the pregnancy rate and the implantation rate for the group in which the LH level fell less than one-third were significantly lower than that of control (p < 0.02). CONCLUSION(S): When performing the mild ovarian stimulation protocol, serum LH should be followed. If the serum LH level is less than one-third at the time of hCG injection, both the pregnancy rate and implantation rate are significantly lower.

Location of endometrial polyp and pregnancy rate in infertility patients.

OBJECTIVE: To assess endometrial polyp location and abnormal endometrial findings and their impact on pregnancy rate. DESIGN: Retrospective study. SETTING: Reproductive clinic in Kanagawa, Japan. PATIENT(S): A retrospective study was conducted on 230 infertility patients who had an endometrial polyp, as suspected on the basis of ultrasound and as diagnosed by hysteroscopy. INTERVENTION(S): Polyps were excised by either polypectomy or curettage. All samples were examined for pathology. The endometrial cavity was subdivided into five area categories: uterotubal junction, anterior uterine wall, posterior uterine wall, lateral uterine wall, and multiple. The patients received < or =6 months of follow-up; pregnancy rates were compared between the five subdivisions. MAIN OUTCOME MEASURE(S): Pregnancy rates. RESULT(S): The incidence of endometrial polyps was as follows, by location: uterotubal junction, 8.0%; posterior uterine wall, 32.0%; anterior uterine wall, 15.4%; lateral uterine wall, 9.2%; and multiple, 35.4%. The pregnancy rate after surgery was as follows, by location: uterotubal junction, 57.4%; posterior uterine wall, 28.5%; anterior uterine wall, 14.8%; lateral uterine wall, 18.8%; and multiple, 40.3%. Endometrial hyperplasia was found in 6.9% of the cases. The pregnancy rate after surgery at the uterotubal junction was significantly higher than that of other locations. CONCLUSION(S): Endometrial polyps are commonly found on the posterior wall of the uterus; however, excision of polyps that were located at the uterotubal junction significantly improved the pregnancy rate. Endometrial polyps should be categorized by both size and location.
