Analysis of Hysterectomy Trends in the Last 5 Years at a Tertiary Center.

Objectives: This study aimed to assess trends by evaluating the types and complications of hysterectomies performed for benign gynecological reasons at our clinic, which is one of the largest hospitals in Turkey. Materials and Methods: Hysterectomies performed for benign reasons at our gynecology and obstetrics clinic between January 1, 2015 and December 31, 2020 were retrospectively reviewed and included in the analysis. Of the 4288 patients who had undergone hysterectomy, 888 patients were excluded some reasons. The data of the remaining 3400 patients were analyzed. Results: For the 3400 patients, the hysterectomy methods performed were as follows: Total Abdominal Hysterectomy (TAH (60%, n = 2055), Total Laparoscopic Hysterectomy (TLH), (27%, n = 948), Vaginal Hysterectomy (VH), (8.9%, n = 302), Conversion from laparoscopy to laparotomy (L / S > LT). (1.4%, n = 49), Robotic hysterectomy (RH), (1%, n = 33), and Subtotal hysterectomy (SH), (0.4%, n = 13). The length of hospital stay was statistically significantly lower in the TLH group than in the TAH group (P < 0.05). A statistically significant and moderate correlation was noted between the length of hospital stay and the duration of operation (r: 0.68 P = 0.00). Conclusion: The ratio of TLH group among hysterectomy modalities has increased over the years. There are many factors that affect the surgeon's decision in determining the hysterectomy method. TLH is the first option in patients who are not suitable for vaginal hysterectomy.

Comparison of relaxant effects of nifedipine and NS11021 on isolated umbilical arteries of healthy and preeclamptic pregnant women.

OBJECTIVES: Potassium (K+) channel openers and calcium (Ca2+) channel blockers are currently used to treat acute severe hypertension in pregnancy. We aimed to investigate the vasorelaxant effect of NS11021, a potent and specific big-conductance Ca2+-activated K+ (BKCa) channel activator, and to compare it with the vasorelaxant effect of nifedipine on human umbilical arteries (HUAs) isolated from healthy and preeclamptic pregnants. STUDY DESIGN: A total of 29 HUAs were isolated immediately after delivery from 14 healthy and 15 preeclamptic pregnant with severe features. The concentration-dependent relaxation responses were obtained to nifedipine and NS11021 on HUAs precontracted with endothelin-1 (ET-1) (10-8 M) in an isolated tissue bath. RESULTS: Both nifedipine and NS11021 caused concentration-dependent relaxation responses in HUAs from healthy and preeclamptic pregnants. While the maximum responses (Emax) and pD2 values of nifedipine did not change significantly in both groups, the Emax and pD2 values of NS11021 were significantly decreased in the preeclampsia group (Emax ± SEM; %75.57 ± 4.53 and %43.75 ± 14.00 and pD2 ± SEM; 6.92 ± 0.26 and 5.24 ± 0.53 respectively, p < 0.05). In addition, the pD2 value of NS11021 was not significantly different from that of nifedipine in the control group, but decreased significantly in the preeclampsia group (pD2 ± SEM 7.1 ± 0.41 and 5.2 ± 0.53, p < 0.05, respectively). CONCLUSIONS: Efficacy and potency of NS11021 decreased in HUAs from preeclamptic pregnants. Also, NS11021 is less potent than nifedipine in the preeclampsia group. BKCa channels may have a role in the pathogenesis of preeclampsia, however, further experimental studies are needed to elucidate that.

Prediction model for residual high-grade cervical intraepithelial lesions.

BACKGROUND: The aim of the study was to evaluate risk factors associated with high-grade cervical intraepithelial lesions (HSIL) in patients undergoing a second cervical excision procedure due to positive surgical margins and to create a prediction model for residual disease. METHODS: This study included patients with HSIL positive surgical margins following loop electrosurgical excision procedures (LEEP) between March 2015 and August 2019. HSIL in the second cervical excision pathology in these patients was accepted as residual disease. For residual disease prediction, a multivariate logistic regression and stepwise elimination analysis of 14 variables including demographic characteristics, clinical characteristics, pathology results and HPV genotypes of the patients was performed. RESULTS: Second cervical excision procedures were performed in 290 patients 85(29.4%) of these patients had CIN 2 (cervical intraepithelial neoplasia) and 205 (70.6%) had CIN 3. In the second excision procedure, 166 patients (57.2%) had ≤CIN 1, 124 patients (42.8%) had ≥CIN2. The prediction model of residual disease includes only 3 variables out of the 14 different clinical characteristics (AUC=0.605 [0.539-0.671]). These variables are gravida (adjusted OR: 1.15 [0.97-1.38], P=0.107), CIN2-3 presence in the endocervical canal in the first LEEP specimen (adjusted OR: 1.52 [0.94-2.47], P=0.091) and the presence of HR-HPV except 16/18 lesions (adjusted OR: 0.64 [0.38-1.06], P=0.083). CONCLUSIONS: A prediction model was designed with our data, from variables reported to be risk factors for residual disease in previous studies. While this model was statistically significant, it was poor at distinguishing residual disease. A prediction model can be designed to guide clinicians with future studies.

Comparison of transendometrial myomectomy versus conventional myomectomy in cesarean section.

OBJECTIVE: To compare the surgical results of transendometrial myomectomy (TEM) and conventional myomectomy (CM) procedures for fibroid in cesarean section. MATERIAL AND METHODS: This retrospective study was conducted with computer-based medical records of patients who underwent myomectomy during cesarean section between January 2013 and March 2019. During the study period, 41 patients underwent transendometrial myomectomy, and 52 patients with had conventional myomectomy. In all patients included in the study, myoma was single, intramural, and localized in the anterior of the uterus. RESULTS: The total duration of surgery was shorter in the TEM group than in the CM group (50,5 ± 10 min vs 63,6 ± 15,2, p = 0,001). There was no difference in terms of length of hospital stay, procedure-related hemoglobin difference, blood transfusion requirement and postoperative fever (respectively, p = 0,65, p = 0,81, p = 0,33 and p = 0,9). Patients who underwent TEM (0.58 ± 0.61) had significantly lower adhesion scores in their subsequent pregnancy compared to patients who underwent CM (1,76 ± 1,1) (p = 0,001). CONCLUSION: Transendometrial myomectomy technique seems to be more advantageous in selected patients compared to the conventional technique due to the shorter operation time.
