Effects of endometrial versus non-endometrial suturing on isthmocele development; a randomized controlled trial.

OBJECTIVE: Incomplete healing after cesarean section (CS) can result in isthmocele formation. When suturing the uterus, fully folding the wound lips may embed the endometrial layer into the myometrium, leading to isthmocele development. Hence, this study aimed to compare the effects of endometrial and non-endometrial suturing on isthmocele development. MATERIAL AND METHODS: This randomized controlled trial included 274 patients. Women who underwent primary CS were randomly allocated to one of the two study groups: endometrial suturing and non-endometrial suturing. The primary outcome was isthmocele rate at postpartum 6 months. Secondary outcomes were the volume of the isthmocele, thickness of the residual myometrium, menstrual irregularities (intermenstrual spotting), and the relationship between the isthmocele and uterine position. RESULTS: A total of 159 patients (81 in the endometrial suturing group and 78 in the non-endometrial suturing group) were analyzed. The incidence of isthmocele was significantly lower in the non-endometrial suturing group than in the endometrial suturing group (12 [15.4%] vs. 24 [29.6%] patients; p = 0.032). Menstrual irregularities, such as intermenstrual spotting, were significantly higher in the endometrial suturing group than in the non-endometrial group (p = 0.019). CONCLUSION: Uterine closure with non-endometrial suturing was associated with significantly lower isthmocele development and less intermenstrual spotting compared to that with endometrial suturing.

Vaginal micronized progesterone versus the levonorgestrel-releasing intrauterine system for treatment of non-atypical endometrial hyperplasia: A randomized controlled trial.

OBJECTIVE: To compare the efficiency of vaginal micronized progesterone (VMP) with the levonorgestrel-releasing intrauterine system (LNG-IUS) in patients with non-atypical endometrial hyperplasia. A validated Menorrhagia Impact Questionnaire (MIQ) was used to assess the quality of life before and after the procedure. METHODS: In this prospective trial, 144 women were randomly assigned to the VMP or LNG-IUS group. The primary endpoint was the regression rate of endometrial hyperplasia after 3 months of treatment. The protocol was approved by the institutional ethics committee and registered at ClinicalTrials.gov (NCT03992937). RESULTS: In all, 138 patients were analyzed. The regression rate was not significantly different between the groups (95.8% with LNG-IUS vs. 90.8% with VMP; P = 0.194). Differences between pre- and post-treatment MIQ scores were similar, except that better scores were obtained in the VMP group for the perception of the amount of blood loss (P = 0.035). CONCLUSION: VMP is as effective as the LNG-IUS as a local treatment of endometrial hyperplasia without atypia. TRIAL REGISTRATION: https://clinicaltrials.gov/ct2/show/NCT03992937.

Extremely high anti-Mullerian hormone levels detected during infertility workup revealing sex cord tumor with annular tubules and underlying Peutz-Jeghers syndrome: A case report.

We report an infertile, but otherwise asymptomatic woman, whose extremely high anti-Mullerian hormone (AMH) level detected during infertility investigation led to the diagnosis of sex cord tumor with annular tubules (SCTAT) which is a very rare sex cord-stromal tumor (SCST) and eventually revealed a previously undiagnosed hereditary cancer syndrome, Peutz-Jeghers syndrome (PJS). A 33-year-old woman attended Kocaeli University ART Clinic for infertility evaluation. Her AMH level was 319.63 ng/ml. Detection of bilateral ovarian cysts required surgical evaluation. The histopathological examination of ovaries revealed SCTAT. The strong association of SCTAT with PJS raised the suspicion of this syndrome. Whole STK11 gene sequencing confirmed PJS diagnosis. AMH has become a widely used tool in the evaluation of infertile women. Clinicians dealing with infertility should be familiar with the utility of AMH measurement besides being a marker of ovarian reserve. Detection of high AMH concentrations should raise the suspicion of an SCST.

Metastatic and synchronous ovarian involvement in low-risk endometrial cancer; clinicopathological analysis with detection of DNA mismatch repair deficiency.

OBJECTIVES: This study aimed to investigate ovarian involvement in low-risk endometrial cancer, the associated risk factors, and impact on overall survival. We attempted to explore the differences in mismatch repair (MMR) deficiency between metastatic and synchronous ovarian tumoral involvement. MATERIAL AND METHODS: This was a retrospective study of patients with low-risk endometrial cancer who were treated at a tertiary center between January 2006 and December 2019. The primary outcome measures were the incidence and risk factors associated with metastatic and synchronous tumoral involvement of the ovary. Overall, survival data were also analyzed. Metastatic and synchronous tumors were compared with each other in terms of MMR deficiency with IHC staining. RESULTS: From a total of 360 low-risk endometrial cancer patients, 10 (2.8%) had ovarian metastasis and 12 (3.3%) had synchronous ovarian involvement. The median age of patients with metastasis was significantly lower than that of patients without ovarian involvement (49 vs 57 years, p = 0.004). Most patients in the metastatic group were in the < 50 age group (p < 0.001) and premenopausal period (p = 0.001). As a result of IHC staining performed on patients with ovarian involvement, MMR deficiency was found in six (60%) patients in the metastatic group and six (50%) patients in the synchronous group. No significant difference was found in overall survival between groups. CONCLUSIONS: Younger age and premenopausal status were risk factors associated with ovarian metastasis. Overall survival did not show differences between all groups, and MMR deficiency was similar between metastatic and synchronous groups.

The concordance between colposcopic biopsy and loop electrosurgical excision procedures in patients with known smear cytology and human papillomavirus results.

Objective: The objective of the study was to evaluate the concordance between colposcopic biopsy and loop electrosurgical excision procedure (LEEP) methods to diagnose cervical pre-invasive lesions and cervical cancer, and to calculate the low and high prediction rates of lesions for both methods. Methods: A total of 241 patients who underwent LEEP after colposcopic biopsy for different indications and also known cervical cytology and human papillomavirus test results were included in the study. Clinical variables such as age, gravida, parity, menopausal status, smoking, endocervical curettage results, and surgical margins were recorded. Results: The total concordance between colposcopic biopsy and LEEP was 41.9%. The rates of finding a more serious lesion than in colposcopic biopsy with LEEP (underestimation) for negative, Cervical Intraepithelial Neoplasia (CIN) 1, CIN 2, and CIN 3 were calculated as 100%, 12.8%, 14.8%, and 3.9%, respectively. Rates of finding a less serious lesion than detected in colposcopic biopsy with LEEP (overestimation) for CIN 1, CIN 2, and CIN 3, cervical carcinoma were calculated as 56.4%, 33.3%, 3.9%, and 0%, respectively. Underestimation was seen in a total of 28 patients, and overestimation was present in 113 patients. Parity was found to be the only associated factor that affected the final diagnosis for high-grade lesions in univariate logistic regression analysis (odds ratio=1.234, 95% confidence interval: 1.005-1.514). Conclusion: Discrepancies between colposcopically directed punch biopsy and subsequent histopathologic LEEP findings are common. New methods to reduce the inconsistency between colposcopic biopsy and LEEP are necessary to prevent patients from being under or over treated.

Application of thrombin gel matrix for the prevention of lymphocele in patients with endometrial cancer: A prospective randomized trial.

OBJECTIVE: To evaluate a thrombin gel matrix (TGM), Floseal, for the prevention of lymphocele in patients with endometrial cancer who underwent pelvic lymphadenectomy. METHODS: A total of 79 consecutive patients with endometrial cancer were randomly allocated to one of two groups: the TGM group and control group. After completion of the lymphadenectomy, 5 mL of Floseal was applied to the bilateral pelvic sidewalls, especially the femoral canal, obturator, and common iliac vessels areas. Computed tomography scans were obtained for lymphocele evaluation 2 months after the surgery. RESULTS: Three patients from the TGM group, and four patients from the control group were lost during follow-up, and data from 36 participants from each group were analyzed. As the primary outcome, lymphocele developed in 12 patients in both groups (33 %). There was no significant difference between the groups in terms of lymphocele and symptomatic lymphocele development. Lymphocele localization was also not different between the two groups, but the diameter of the lymphoceles detected in the TGM group was significantly greater (p = 0.021). The mean drainage days was significantly shorter in the TGM group (p = 0.015). The amount of drainage was also less in the TGM group, but the difference was not statistically significant. CONCLUSION: Thrombin gel matrix applied to the pelvic sidewalls does not reduce the incidence of symptomatic or asymptomatic lymphoceles after pelvic lymphadenectomy in endometrial cancer. However, it can reduce the amount of drainage and the number of drainage days so it can help to shorten hospitalization.

Branch retinal artery occlusion in a patient undergoing Methotrexate therapy for ectopic pregnancy: A case report.

Methotrexate is a commonly used agent in the treatment of an un-ruptured ectopic pregnancy. Thromboembolic events are rarely seen side effects of such a medicine. We report the case of the 22-year-old woman who underwent Methotrexate therapy for an un-ruptured ectopic pregnancy without any history of thromboembolic risk factors. A second dose (50 mg/m2) was administered to the patient showing a nondecreasing pattern of ß-HCG levels after an initial standard dosage of Methotrexate (50 mg/m2). On the 12th day of the treatment, a sudden onset of painless vision loss was seen in the right eye. Fundal imaging and fluorescein angiography revealed an occlusion of the superior temporal branch of the right retinal artery. After a month of hyperbaric oxygen therapy, complete recovery without loss of vision was achieved.

Cervical versus endometrial injection for sentinel lymph node detection in endometrial cancer: a randomized clinical trial.

OBJECTIVE: To evaluate the relationship between pelvic/para-aortic sentinel lymph node status and two different injection sites of 99m-technetium (99mTc)-labeled phytate in patients with endometrial cancer. METHODS: This was a randomized controlled trial involving 81 patients with endometrial cancer. In the cervical group (n=40), injections of 99mTc were performed at the 3 and 9 o'clock positions of the uterine cervix. In the endometrial group (n=41), 99mTc was injected into the fundal endometrium using a transcervical catheter. Sentinel lymph nodes were detected through pre-operative lymphoscintigraphy and intra-operatively using a handheld gamma probe. All patients underwent complete pelvic and para-aortic lymphadenectomy procedures. Pathologic ultra-staging was performed with immunostaining for cytokeratin in sentinel lymph nodes after routine hematoxylin and eosin histological examinations. The primary endpoint was the estimation of detection rates, sensitivity, false-negative rates, negative predictive value, and analysis of the distribution of pelvic and para-aortic sentinel lymph nodes. RESULTS: The rate of detection of at least one sentinel lymph node, sensitivity, and the negative predictive value was 80%, 66.6%, 96.6% for the cervical group and 85%, 66.6%, 96.9% for the endometrial group, respectively. False-negative sentinel lymph nodes were detected in one patient from each group . There was no significant difference between the groups in terms of total sentinel lymph node count, sentinel pelvic lymph node count, and pelvic bilaterality, but the para-aortic sentinel lymph node count was significantly higher in the endometrial group (p<0.001). Ultra-staging examination of the pelvic sentinel lymph nodes revealed isolated tumor cells in one patient from each group. CONCLUSION: Transcervical endometrial tracer injection in endometrial cancer revealed similar pelvic but significantly higher para-aortic sentinel lymph node detection.

Povidone-iodine vs chlorhexidine alcohol for skin preparation in malignant and premalignant gynaecologic diseases: A randomized controlled study.

OBJECTIVES: To compare povidone-iodine with chlorhexidine alcohol solutions for the prevention of surgical site infection (SSI) in malignant and premalignant gynaecologic diseases, and to evaluate the effects of temperature on SSI at 25 °C and 37 °C. STUDY DESIGN: This was a randomized controlled trial of a cohort of 220 patients undergoing surgery for malignant or premalignant conditions. Preoperative skin preparations were performed with 10% povidone-iodine at 25 °C (PI), 10% povidone-iodine at 37 °C (warm PI), 4% chlorhexidine gluconate with alcohol at 25 °C (CH) and 4% chlorhexidine gluconate with alcohol at 37 °C (warm CH) for each group. All women included in the study received 1 g intravenous cefazolin antibioprophylaxis 30 min before skin incision. The primary outcome was SSI within 30 days of surgery, and secondary outcomes were identification of the causative organism and clinical factors that may be associated with SSI. RESULTS: SSIs were detected in 24 (10.9%) patients. Except for two organ/space-specific SSIs, all were superficial SSIs. The frequency of SSI was significantly lower in the warm PI group than in the PI group (p = 0.032). There were no significant differences in the frequency of SSI between the groups in other binary comparisons. In addition, there was no significant difference between both povidone-iodine groups compared with both chlorhexidine alcohol groups in terms of the development of SSI (10.9% vs 11%, p = 1.00). SSI caused by micro-organisms was found in 18 patients, and Enterococcus faecalis was the most common reproducing organism in wound culture. Patients with SSI were significantly older (58.9 ± 11.4 vs 52.8 ± 12.3 years) and more likely to be readmitted to hospital [15 (62.5%) vs 9 (37.5%)] than patients without SSI. CONCLUSIONS: SSI rates can be reduced by warming povidone-iodine, but this effect could not be demonstrated with chlorhexidine solutions. When both groups of povidone-iodine were compared with both groups of chlorhexidine alcohol, no significant difference was found in the prevention of SSI in malignant and premalignant gynaecologic operations.

Transurethral excision and re-erosion of mesh material after transobturator tape surgery: A case report.

Bladder injury is a rare complication of transobturator tape surgery. Herein, we present a female case in whom intravesical mesh was excised using transurethral endoscopic scissors, and another floating mesh material with calculi formation was seen in bladder and excised with endoscopic forceps 2 months later.

Primary pulmonary sarcoma metastasising to the skin during pregnancy.

Lung cancer during pregnancy is a rare situation which is being increasingly reported during the past two decades due to a rising trend of cigarette smoking among young women and the tendency to delay pregnancy to a later age in life. We describe the case of a 32-year-old woman with primary pulmonary sarcoma, diagnosed at 31st week of pregnancy. X-ray chest and thoracic magnetic resonance imaging revealed a 9 x 6 cm mass in the left mediastinum, with tracheal shift, and pleural effusion. Biopsy performed during broncoscopy, was reported as mesenchymal tumour. She delivered a baby by Caesarean section at the 32nd week of gestation due to the development of superior vena cava syndrome. A skin biopsy taken 3 weeks later from the nodular lesion at the periumblical region was reported as a tumour metastasis. She received radiotherapy for 10 days, but died in the intensive care unit. Malignancies, even those as uncommon as a pulmonary sarcoma, should be considered in the differential diagnosis of pleural effusion during pregnancy.

Use of an aromatase inhibitor in patients with polycystic ovary syndrome: a prospective randomized trial.

OBJECTIVE: To compare the use of an aromatase inhibitor (letrozole) with the use of clomiphene citrate (CC). DESIGN: Prospective randomized study. SETTING: An infertility clinic in a university hospital. PATIENT(S): Seventy-four consecutive infertile patients with polycystic ovary syndrome were recruited. Thirty-eight patients were randomized to the letrozole group (99 cycles), and the remaining patients were recruited to the CC group (95 cycles). INTERVENTION(S): The aromatase inhibitor letrozole (2.5 mg/d) and CC (100 mg/d) were administered orally on days 3-7 of menses. MAIN OUTCOME MEASURE(S): Number of follicles, endometrial thickness, E(2) levels on hCG day, and pregnancy rates among both groups. RESULT(S): Ovulation occurred in 65.7% (65/99) of letrozole cycles and in 74.7% (71/95) of CC cycles. The median (minimum-maximum) number of follicles sized >15 mm in diameter on the day of hCG administration were 1 (0-4) and 1 (0-5) in the letrozole and CC groups, respectively. On the day of hCG administration, median serum E(2) concentrations in the letrozole and CC groups were statistically significantly different: 189 pg/mL (18-1,581 pg/mL) and 386 pg/mL (27-6,190 pg/mL), respectively. The median serum E(2) concentrations per follicle sized >15 mm in diameter on the day of hCG also statistically significantly differed between the letrozole and CC groups: 160 pg/mL (18-808 pg/mL) and 281 pg/mL (27-2,615 pg/mL), respectively. The median endometrial thickness on the day of hCG did not significantly differ between the CC and letrozole groups; it was 8 mm. Pregnancy was achieved in nine cycles (9.1%) of the letrozole group and in seven cycles (7.4%) of the CC group, which also was not a statistically significant difference. CONCLUSION(S): The aromatase inhibitor letrozole may be an acceptable alternative to CC as an ovulation-induction drug in patients with PCOS.
