Item Importance of Laparoscopy in Predicting Complete Cytoreduction at Advanced Stage Ovarian Cancer(2022) Durdag, Gulsen Dogan; Alemdaroglu, Songul; Baran, Safak Yilmaz; Serbetcioglu, Gonca Coban; Ozmete, Ozlem; Ezer, Ali; Celik, Husnu; https://orcid.org/0000-0003-4335-6659Purpose Laparoscopy has been used in evaluation of ovarian cancer to assess the extent and surgical resectability of the disease, and to avoid futile laparotomy, where primary cytoreduction is not suitable. Aim of this study is to investigate the contribution of laparoscopy in predicting 'no gross residue' in advanced stage ovarian cancer. Methods Data of advanced stage ovarian cancer patients, who underwent diagnostic laparoscopy for prediction of complete cytoreduction due to an alternative model, are analyzed retrospectively. Accordingly, in the absence of obvious mesenteric retraction or extensive tumoral implants on small intestine in laparoscopic assessment, cases were deemed surgically resectable, and the operation was continued with laparotomy to achieve complete cytoreduction. Clinical features of the patients, surgical details, complete and optimal cytoreduction rates, and perioperative complications were evaluated. Results Out of 243 patients with advanced stage ovarian/tubal/peritoneal cancer, laparoscopy was performed at 93 patients, 77 of whom underwent primary cytoreduction subsequently. Complete cytoreduction (no gross residue) and optimal cytoreduction (< 1 cm residual tumor) rates were 75.3 and 100%, respectively. None of the patients had suboptimal surgery. Morbidity and mortality rates were acceptable. Conclusion Laparoscopic evaluation prior to cytoreductive surgery can highly contribute to prediction of complete or optimal cytoreduction in suitable patients. However, experience and skills of the surgeon, as well as technical equipment of the center, may affect surgery; therefore, the model to predict residual tumor should be individualized according to the set up and the surgical team of each center.Item Reappraisal of the relationship between 24-hour proteinuria and preeclampsia in terms of the maternal and perinatal outcomes(2020) Yilmaz Baran, Safak; Alemdaroglu, Songul; Durdag, Gulsen Dogan; Yetkinel, Selcuk; Yuksel Simsek, Seda; Kalayci, Hakan; Simsek, Erhan; 0000-0003-4335-6659; 0000-0002-5064-5267; 0000-0002-2165-9168; 32037908; AAK-7016-2021; AAK-7016-2021; AAK-7016-2021; AAK-7016-2021; AAK-7016-2021Objective: This study evaluated the association between proteinuria levels and maternal, and perinatal outcomes of preeclampsia patients and determined the cutoff values for predicting severe complications. Methods: We retrospectively evaluated the records of 412 patients with proteinuric preeclampsia. Results: Median proteinuria levels were significantly higher in patients with severe maternal and adverse perinatal outcomes than in those without such outcomes, except in cases of placental abruption and late preterm delivery. Conclusion: Proteinuria levels may aid in diagnosing preeclampsia and indicating early intervention. The revised guidelines do not suggest that proteinuria encountered during pregnancy is clinically insignificant.Item An analysis of 635 consequetive laparoscopic hysterectomy patients in a tertiary referral hospital(2020) Yuksel, Seda; Serbetcioglu, Gonca Coban; Alemdaroglu, Songul; Yetkinel, Selcuk; Durdag, Gulsen Dogan; Simsek, Erhan; Celik, Husnu; 0000-0002-5064-5267; 0000-0002-3285-5519; 0000-0003-4335-6659; 0000-0002-2165-9168; 31610294; AAK-7016-2021; AAI-9594-2021; AAI-9974-2021; AAI-8400-2021; AAL-1530-2021Objective: The objective of this retrospective observational study is to analyse the properties of laparoscopic hysterectomy cases that are performed for benign indications and also endometrial cancer indications. Operation time, postoperative complicaton rate, blood transfusion need, and hospitalization time are compared according to benign and malign indications and also body mass index of the patients. Material and methods: Patients who were operated between September 2012 and December 2017 are included in this study. Patients' age, body mass index, medical histories, operation indications, operation time, pathology reports, pre and postoperative hemoglobine values and postoperative complications are obtained from medical records.Body mass index is classified as underweight for <19 ; normal for 19-25 ; overweight for 25-30 and obese for >= 30. Results: Operation and hospitalization times were significantly higher for high BMI and malign gynecologic indication groups than lower BMI and benign gynecologic indication groups (p:0.0001). Complication rates and transfusion needs were similar in between malign and benign gynecologic disease groups (p :0.443; P:0.670 respectively) and also in between high and lower BMI groups (P:0.813 ; P:0.468 respectively). Conclusion: Laparoscopic approach for hysterectomy operations in high BMI patients and endometrial cancer patients seem to be safe in terms of postoperative complication and bleeding that necessitate transfusion.

We aim to compare the maternal, laboratory and perinatal characteristics of both groups. Materials and method: The records of 10,929 patients who gave birth in the center between October 2011 and July 2019 were analyzed retrospectively from the data processing system records. Maternal, laboratory and perinatal characteristics of 109 single pregnancies (spontaneous n: 91; IVF n: 18) diagnosed with ICP were compared. Findings: The maternal demographic data of both groups were similar (p: .05). In both groups, gestational week, gestational age at birth, birth weight, neonatal intensive care admission rate, meconium-stained amniotic fluid, umbilical cord pH, the 5-minute APGAR score, and the presence of pregnancy complications were similar (p > .05). Result: Although ICP is reported with a higher incidence in IVF pregnancies, ICP findings and prognosis are similar to those of spontaneous pregnancies.Item Lumbosacral discitis as a rare complication of laparoscopic sacrocolpopexy(2020) Durdag, Gulsen Dogan; Alemdaroglu, Songul; Durdag, Emre; Simsek, Seda Yuksel; Turunc, Tuba; Yetkinel, Selcuk; Baran, Safak Yilmaz; Celik, Husnu; 0000-0001-6939-5491; 0000-0002-2165-9168; 0000-0002-5064-5267; 0000-0003-4335-6659; 32500164; AAK-1734-2021; AAL-1530-2021; AAI-9594-2021; AAK-7016-2021; AAI-8400-2021; ABF-6439-2020Introduction and hypothesis Sacrocolpopexy is considered to be the gold-standard procedure for apical compartment prolapse. However, complications such as sacral hemorrhage, small bowel obstruction, port site herniation, mesh erosion, mesh exposure, and occasionally discitis may occur. The aim of this study is to show laparoscopic treatment of L5-S1 discitis 3 months following laparoscopic sacrocolpopexy. Methods Two surgical interventions of a case with narrated video footage is presented. Results Laparoscopic sacrocolpopexy following hysterectomy in the first part and re-laparoscopy because of a diagnosis of discitis refractory to medical treatment, and removal of mesh along with anterior L5-S1 discectomy for curative debridement in the second part is demonstrated. Conclusion Frequency of postoperative discitis has been increased by the widespread use of a laparoscopic approach. In order to reduce the complication rate, surgical technique allowing the needle to penetrate only the depth of the anterior longitudinal ligament and usage of monofilament suture for mesh attachment is recommended. In treatment, removal of the sacral mesh, and even extensive tissue debridement, may be necessary.Item Pregnancy and immune thrombocytopenia: New trends Response(2020) Kalayci, Hakan; Durdag, Gulsen Dogan; Baran, Safak Yilmaz; Simsek, Seda Yuksel; Alemdaroglu, Songul; Ozdogan, Serdinc; Kilicdag, Esra Bulgan; 0000-0002-5064-5267; 0000-0002-0942-9108; 0000-0003-4335-6659; AAI-9594-2021; AAK-8872-2021; AAI-8400-2021; AAK-7016-2021; ABF-6439-2020Item Role of prophylactic and therapeutic red blood cell exchange in pregnancy with sickle cell disease: Maternal and perinatal outcomes(2020) Baran, Safak Yilmaz; Kozanoglu, Ilknur; Korur, Asli; Durdag, Gulsen Dogan; Kalayaci, Hakan; Alemdaroglu, Songul; Asma, Suheyl; Kilicdag, Esra Bulgan; Boga, Can; 0000-0002-0942-9108; 0000-0002-5086-5593; 0000-0002-5268-1210; 0000-0003-4335-6659; 0000-0001-5335-7976; 0000-0002-5064-5267; 0000-0002-8902-1283; 0000-0001-5874-7324; 0000-0002-9680-1958; 32797735; ABF-6439-2020; AAK-8872-2021; AAD-5616-2021; AAD-6222-2021; AAE-1241-2021; AAI-8400-2021; AAI-7831-2021; AAI-9594-2021; AAD-5542-2021Background and Aim The incidence of fetomaternal complications during pregnancy is high for women with sickle cell disease (SCD), which is the most common hematologic genetic disorder worldwide. Prophylactic red blood cell exchange (pRBCX) has been shown to be efficient, safe, and feasible for preventing complications. The aim of this study was to observe maternal, perinatal, and neonatal outcomes of pregnancies in which pRBCX was. Method This was a single-center, retrospective, cross-sectional study, which recruited 46 consecutive adult pregnant women with SCD between January 2012 and June 2019. Obstetric features, SCD-related complications, and fetomaternal outcomes were compared between the 27 patients who received prophylactic exchange and the 19 who did not (therapeutic exchange was performed in 7 and was not performed in 12 cases). Results Painful crises, preeclampsia, and preterm birth rates were significantly higher in the group that did not receive prophylactic exchange (control group;P= .001,P= .024, andP= .027, respectively). There was one maternal mortality in the control group (P= .41). Incidence of adverse fetal or maternal complications was significantly higher in the control group (P= .044 andP= .007, respectively). Conclusions Our center's experience over a 7.5-year period, as described above, demonstrates that pRBCX in SCD affects the course of pregnancy positively by ameliorating negative fetomaternal outcomes.Item Does abnormal ductus venosus pulsatility index at the first-trimester effect on adverse pregnancy outcomes?(2020) Baran, Safak Yilmaz; Kalayci, Hakan; Durdag, Gulsen Dogan; Yetkinel, Selcuk; Arslan, Alev; Kilicdag, Esra Bulgan; 0000-0002-2165-9168; 0000-0002-5064-5267; 0000-0002-0942-9108; 0000-0003-4444-0027; 0000-0001-5874-7324; 32623067; AAL-1530-2021; AAI-9594-2021; AAK-8872-2021; V-1112-2019Aim: The ductus venosus pulsatility index for veins (DV PIV) has become a popular marker of the first-trimester scan. The aim of this study is to search for any difference between groups with normal and abnormal DV PIV values in terms of adverse pregnancy outcomes. Methods: We retrospectively evaluated 556 women whose first-trimester scan was performed. The ductus venosus pulsatility indices were examined at singleton pregnancies between 11 and 14 weeks of gestation. Patients were categorized as Group-I with normal DV PIV (DV PIV >= 0.73, <= 1.22) and as Group-II with abnormal DV PIV. Group-II was subgrouped as Group-IIA which composed of patients with DV PIV < 0.73 and as Group-IIB with DV PIV > 1.22. Results: There were 451 subjects in Group-I and 105 subjects in Group-II (Group-IIA = 32 and Group-IIB 73). The comparisons between major groups revealed a statistically significant increase about miscarriage (p = 0.002), stillbirth (p < 0.001), small for gestational age (p = 0.033), low birth weight (p < 0.001), fetal growth restriction (p = 0.048), and major congenital heart defect (p=<0.001) in Group-II. This difference is mainly due to Group-IIB. There is no difference in preterm delivery, preeclampsia and gestational diabetes between Group I and II. Conclusion: Routinely monitoring DIV PIV as a first-trimester screening should provide valuable information regarding adverse pregnancy outcomes such as miscarriage, stillbirth, small for gestational age, low birth weight, fetal growth restriction and major congenital heart defect.

Fetal magnetic resonance imaging (MRI) can be used to confirm the ultrasound diagnose or to detect additional anomalies. Aim of this study is to assess follow up and management of fetal ventriculomegaly shown by ultrasound, and to evaluate additional diagnostic contribution of MRI. Study Design: This study was conducted retrospectively including 89 patients who had fetal MRI subsequent to ultrasound diagnose of ventriculomegaly in between 2011-2017. Medical records of patients were investigated and accompanying anomalies, congenital infection. chromosomal examination, degree and progression of ventriculomegaly, neonatal imaging and diagnose, and neurodevelopmental findings on follow up were evaluated. Patients were classified in two groups as isolated and nonisolated ventriculomegaly, and subgroups mild, moderate, severe were formed according to their findings. SPSS 23.0 programme was used for statistical analysis. Results: Ultrasound and following MRI was performed in a range of 18-35 th gestational weeks, diagnoses were isolated ventriculomegaly for 56 patients and nonisolated ventriculomegaly for 33 patients. Progression and neurodevelopmental delay was higher in severe nonisolated ventriculomegaly group. There was not significant contribution of MRI in the follow up of isolated ventriculomegaly (p < 0.001), and diagnostic imaging findings declined in neonatal period with proceeding normal neurodevelopment in 92.7% of patients followed with diagnosis of isolated ventriculomegaly. Conclusion: When isolated ventriculomegaly is detected, ultrasound performed by an experienced team is mostly sufficient. MRI can be used in suspicious cases or when ventriculomegaly progresses.
