Could Birth Weight to Placental Weight Ratio Predict Postpartum Haemorrhage and Neonatal Intensive Care Unit Admission?

OBJECTIVE: To evaluate the usability of the ratio of birth weight to placental weight [fetoplacental ratio (FPR)] in predicting postpartum haemorrhage (PPH) and neonatal intensive care unit (NICU) admission. STUDY DESIGN: Prospective observational study. PLACE AND DURATION OF STUDY: Bursa Yuksek Ihtisas Training & Research Hospital, Bursa, Turkey, between July 2020 and July 2021. METHODOLOGY: Women who were supposed to have an uncomplicated delivery with a live, single, term pregnancy without any concomitant disease, were included in the study. Patients with PPH were accepted as the study group and patients without PPH were the control group. For NICU requirement, babies who were admitted to NICU were the study group, and babies who did not require NICU were the control group. The fetoplacental ratio was calculated by dividing the newborn weight to placental weight and evaluated in the prediction of NICU admission and PPH. RESULTS: The number of patients included in the study was 812. Approximately 7% of women had postpartum haemorrhage. The FPR was found as an independent predictor for PPH by nearly 3.5 fold. Women who experienced PPH had heavier placenta and lower fetoplacental ratio. Patients whose babies were admitted to NICU also had lower FPR with statistically significant differences. CONCLUSION: The fetoplacental ratio could be a promising predictor for PPH and NICU admission in the postpartum period. Since novel studies are needed using ultrasonographic measurements during antenatal surveillance to predict PPH or NICU admission. KEY WORDS: Birth weight, Neonatal intensive care unit, Placental weight, Postpartum haemorrhage, Cesarean birth, Vaginal birth, Fetoplacental ratio.

Short interdelivery interval in modern obstetrics: Maternal and neonatal outcomes.

Objective: To investigate the maternal, neonatal outcomes of the patients with short interdelivery interval (IDI) considering initial pregnancy outcomes. Materials and Methods: Women with two consecutive deliveries between 2016 and 2020 were included in the study. The maternal and neonatal outcomes of both pregnancies were reviewed. The time interval between consecutive deliveries was calculated. The patients were divided into two groups in terms of IDI either less or more than 24 months. Results: The number of patients with short IDI (≤24 months), and normal IDI was 1.915 and 1.370, respectively. About 15% of the women in both groups had at least one obstetric morbidity. The rates of uterine rupture, placenta previa, and peripartum hysterectomy were higher in women with short IDI. The number of patients with low birth weight, very low birth weight, and stillbirth was higher in the short IDI group. Conclusion: Patients with short interpregnancy intervals should be considered high-risk pregnancy. Adequate contraceptive methods should be used to prevent unintended pregnancies.

Comparison of perioperative outcomes between colpocleisis with hysterectomy and colpocleisis without hysterectomy.

STUDY OBJECTIVE: To evaluate the effect of concomitant hysterectomy on perioperative outcomes in patients who underwent obliterative pelvic organ prolapse (POP) surgery. MATERIAL AND METHODS: This retrospective study included 95 consecutive patients with no prior hysterectomy who underwent obliterative surgery for POP between February 2015 and April 2021. Perioperative outcomes of colpocleisis without hysterectomy (C) and colpocleisis with hysterectomy (CH) were compared. RESULTS: Of the 95 patients, 49 (51.6%) underwent C and 46 (48.4%) underwent CH. Patient characteristics including age, body mass index and history of prolapse surgery were comparable between the groups (P-values .367, .199, and .363, respectively). The rate per prolapse stage, from stage 2 to stage 4, was similar in both groups (P-values .709, >.999, and .838 for Stage 2, Stage 3, and Stage 4, respectively). The mean operating time was shorter in the C group than in the CH group (68.9 ± 25.7 minutes versus 94.7 ± 23.1 minutes, P-value < .001). Other perioperative outcomes including postoperative hemoglobin drop, duration of Foley catheter, rate of intraoperative complications, rate of patients with postoperative adverse events, reintervention rate and readmission rate were comparable in both groups (P-values .125, .362, .484, > .999, .495, and > .999, respectively). CONCLUSION: CH is associated with a longer operative time compared to C. However, concomitant hysterectomy does not appear to affect perioperative outcomes other than the operative time negatively.

Transvaginal natural orifice transluminal endoscopic surgery for ectopic pregnancy.

AIMS: This study aims to describe our transvaginal natural orifice transluminal endoscopic surgery (vNOTES) technique for ectopic pregnancy that can be performed using conventional laparoscopic equipment with the addition of a self-constructed pessary port and to evaluate the safety, feasibility, and outcomes of the technique. METHODS: This is a retrospective study evaluating outcomes of patients who underwent vNOTES for ectopic pregnancy (n = 21) between August 2019 and April 2021. RESULTS: Twenty-one patients underwent vNOTES as intended without any intraoperative complications. Three patients (14.3%) were nulliparous, 16 patients (76.2%) had no history of vaginal delivery, and 13 patients (61.9%) had a history of at least one cesarean delivery. Eight patients (38.1%) had a history of previous abdominal surgery other than cesarean section. The mean duration of surgery was 43.4 ± 12.6 min. The mean visual analog scale scores for pain were 2.45 ± 1.13 at 2 h after surgery, 0.45 ± 0.83 at 12 h after surgery, and 0.18 ± 0.36 at 24 h after surgery. The median duration of postoperative hospital stay was 1 day (range, 1-2). There were no postoperative complications within 30 days after surgery. CONCLUSIONS: vNOTES can be performed in an existing laparoscopy setup with the addition of a self-constructed pessary port. vNOTES is a safe and effective surgical treatment option for ectopic pregnancy, even in patients who have not had a vaginal delivery and have had multiple abdominal surgeries.

Impact of transvaginal natural orifice transluminal endoscopic surgery on hysterectomy practice.

STUDY OBJECTIVE: To evaluate the impacts of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) on the hysterectomy route and concomitant adnexal surgery at the time of vaginal hysterectomy (VH). MATERIAL AND METHODS: This retrospective study analyzed all hysterectomies performed for benign indications between 1 January 2017 and 31 December 2019. The period preceding the first case of VH and vNOTES BSO was considered as Pre-vNOTES. The period starting from the date of the first case was considered as Post-vNOTES. The rates per route of hysterectomy and the rate of concomitant adnexal surgery at the time of VH were compared between the two periods. RESULTS: In hysterectomies performed by surgeons who implemented vNOTES, the proportion of the vaginal route increased from 40.1% to 94.3% (P-value < 0.001); the abdominal route decreased from 37.4% to 3.2% (P-value < 0.001); and the laparoscopic route decreased from 22.5% to 2.5% (P-value < 0.001). The rates of concomitant adnexal procedures performed at the time of VH also showed significant changes. While 39.7% of patients did not undergo any concomitant adnexal surgery during the Pre-vNOTES period, this rate dropped to 8.1% after the implementation of vNOTES (P-value < 0.001). Similarly, the rate of bilateral salpingectomy dropped from 49.3% to 14.2% (P-value < 0.001), whereas the rate of BSO increased from 6.8% to 75% (P-value < 0.001). CONCLUSION: Implementation of vNOTES has led to a significant increase in the rate of VH and the rate of concomitant BSO at the time of VH.

Vaginal approach versus laparoscopy for hysterectomy in transgender men.

STUDY OBJECTIVE: To describe a vaginal approach combining vaginal hysterectomy (VH) with transvaginal natural orifice transluminal endoscopic surgery (vNOTES) bilateral salpingo-oophorectomy (BSO) for hysterectomy in transgender men and to evaluate the feasibility, safety, and surgical outcomes of this approach in comparison with laparoscopy. MATERIAL AND METHODS: Retrospective cohort study comparing outcomes of the vaginal approach (n = 45) and laparoscopy (n = 45) in transgender men undergoing hysterectomy between May 2017 and June 2020. RESULTS: There was one intraoperative complication (bladder injury) in the laparoscopy group, which was the reason for the only conversion from the initial surgical approach. All vaginal procedures were completed without any intraoperative complications or conversions. Patients in the vaginal approach group had shorter operative times compared to the laparoscopy group (median 60 [range, 30-130] vs median 85 [range, 63-179] minutes; P < 0.001). One patient in the vaginal approach group experienced late-onset intraabdominal bleeding and underwent reoperation on postoperative day 4 after failed expectant management. There were no reoperations in the laparoscopy group. Patients in the vaginal approach group experienced less pain at postoperative 12 h and 24 h (P values < 0.001 and < 0.001, respectively). Postoperative hospital stay was shorter in the vaginal approach group than in the laparoscopy group (median 2 [range, 1-7] vs. median 2 [range, 2-6] days; P < 0.001). There were no readmissions within 30 days after surgery in either group. CONCLUSION: The vaginal approach combining VH with vNOTES BSO is a feasible and safe alternative to laparoscopy for hysterectomy in transgender men.

Laparoscopic view of endosalpingiosis in a woman with dermoid cyst and endometriosis

Endosalpingiosis is, like endometriosis, the presence of cystic masses outside of the salpinx which contains fallopian tube epithelium. Endosalpingiosis can be seen on the surface of ovaries, tubal serosa, uterine serosa, myometrium, and also in the bladder. The main clinical features of endosalpingiosis are pelvic pain, adnexal mass which mimics cancer, and urinary symptoms. Herein, we present a surgical video of endosalpingiosis in a woman with endometriosis and a dermoid cyst.

Oxytocin and cabergoline alleviate ovarian hyperstimulation syndrome (OHSS) by suppressing vascular endothelial growth factor (VEGF) in an experimental model.

PURPOSE: Ovarian hyperstimulation syndrome (OHSS) is a life-threatening complication of ovarian stimulation in reproductive medicine. Here, we aimed to investigate the role of oxytocin (OT) and cabergoline in the prevention and alleviation of the OHSS in an animal model. METHODS: Thirty-five female immature Wistar rats were randomly assigned to five groups. The control group (n = 7) received saline only for five consecutive days. Remaining twenty-eight rats received 10 IU of pregnant mare serum gonadotropin (PMSG) followed by 30 IU of human chorionic gonadotropin (hCG) to induce OHSS. Group 2 (n = 7) was managed with no additional intervention after the induction of OHSS. Group 3 (n = 7) received 100 µg/kg cabergoline 2 h before the PMSG injection for four consecutive days and 2 h before the hCG injection on the fifth day. Group 4 (n = 7) and group 5 (n = 7) received 80 µg/kg and 160 µg/kg OT after induction of OHSS, respectively. Oxytocin was administered 2 h before the PMSG injection for four consecutive days and 2 h before the hCG injection on the fifth day. Body and ovary weight, vascular permeability (VP), VEGF expression in the ovaries, and levels of VEGF in the peritoneal fluids were examined in all animals. RESULTS: Cabergoline and OT reduced body weight, ovary weight, and VP compared to that of the OHSS group (p < 0.05). VEGF expressions in ovaries and peritoneal VEGF levels were decreased in cabergoline and OT groups compared to that of the OHSS groups (p < 0.001 for cabergoline and OT-80 µg/kg; p < 0.00001 for OT-160 µg/kg). However, there was no statistically significant difference in these parameters between the OT and cabergoline groups. CONCLUSION: Both OT and cabergoline were active in the alleviation of OHSS through suppression of VEGF and VP. Overall, we conclude that OT is effective for downregulation for VEGF and improvement in vascular permeability in OHSS.

Transvaginal Natural Orifice Transluminal Endoscopic Surgery for Tubal Stump Pregnancy.

OBJECTIVE: To demonstrate a case of left tubal stump pregnancy successfully treated using our 2-step technique for transvaginal natural orifice transluminal endoscopic surgery (vNOTES). DESIGN: Demonstration of the technique using surgical video footage. SETTING: Tertiary university hospital. INTERVENTIONS: A 27-year-old gravida 3 para 0 patient with a history of laparotomy, left salpingectomy owing to a ruptured tubal pregnancy, was referred to our hospital because of a pregnancy of unknown location. Her serum ß human chorionic gonadotropin level was 8400 U/L, and a transvaginal ultrasound revealed an ectopic pregnancy in the left tubal stump. After discussing medical and surgical treatment options, the patient underwent a 2-step vNOTES approach. First, a diagnostic vNOTES was performed using a 5-mm trocar with autoretracting blade. After confirmation of the diagnosis, the trocar was removed, and the incision was enlarged with blunt dissection. A self-constructed pessary port was then placed through the enlarged colpotomy, and the ectopic pregnancy in the left tubal stump was excised using an advanced bipolar device. The colpotomy was closed with running resorbable sutures. The duration of the surgery was 36 minutes, and the patient was discharged on postoperative day 1 without any complications. CONCLUSION: Tubal stump pregnancy is a rare form of ectopic pregnancy with an incidence of approximately 0.4% of all ectopic pregnancies [1]. Treatment options include conservative medical management using methotrexate and surgery. Successful surgical treatment using laparoscopy has been previously reported [1,2]. This case demonstrates that vNOTES may be a minimally invasive option for the surgical treatment of tubal stump pregnancy in selected cases.

Simplified two-step technique for transvaginal natural orifice transluminal endoscopic surgery.

OBJECTIVE: To describe our simplified two-step technique for transvaginal natural orifice transluminal endoscopic surgery (vNOTES) and to demonstrate the application of the technique. DESIGN: Step-by-step description of the technique and demonstration of its application using surgical video footage from two different cases. SETTING: Tertiary university hospital. PATIENT(S): Patient 1 was a 27-year-old G0P0 woman who presented with right lower quadrant pain. Transvaginal ultrasound scan revealed a right ovarian torsion. Patient 2 was a 25-year-old G3P2 woman. She presented with vaginal bleeding and left lower quadrant pain. Her serum ß-human chorionic gonadotropin level was 28,313 U/L, and transvaginal ultrasound scan revealed an ectopic pregnancy in the left tube. The decision to perform vNOTES was made for both patients. INTERVENTION(S): As the first step, patients underwent diagnostic vNOTES. The patient was placed in lithotomy position under general anesthesia. By use of a 5-mm trocar with autoretracting blade, a colpotomy was performed on the posterior vaginal wall. Pneumoperitoneum was achieved, and the patient was placed in a Trendelenburg position. A 5-mm 30° rigid endoscope was introduced, and the diagnosis was confirmed. After the confirmation of the diagnosis, we proceeded to the second step. The colpotomy was enlarged with blunt dissection by using Metzenbaum scissors. A self-constructed pessary port was placed through the colpotomy, and pneumoperitoneum was achieved. The therapeutic procedure was then performed. Patient 1 underwent ovarian detorsion with a 5-mm laparoscopic grasper. After the ovary was detorsioned, a 5-mm bipolar instrument was used to achieve hemostasis. Patient 2 underwent left salpingectomy with a 5-mm advanced bipolar device. Hemostasis was verified, and the specimen was extracted through the colpotomy. Procedures ended with the closure of colpotomy with running resorbable sutures. MAIN OUTCOME MEASURE(S): Description of the technique and demonstration of its applicability in two common gynecological emergencies. RESULT(S): Both patients were treated successfully by vNOTES. The operating times were 25 minutes and 38 minutes for patient 1 and patient 2, respectively. Patients were discharged on postoperative day 1 without any complications. CONCLUSION(S): Our simplified two-step technique described and demonstrated in this video article is a feasible and practical approach to perform vNOTES. The first step allows the confirmation of the diagnosis and facilitates the colpotomy. The use of the self-constructed pessary port enables to perform surgery with already existing equipment without the need for specialized equipment and without increasing the costs.

The Role of Ankaferd Blood Stopper and Oxytocin as Potential Therapeutic Agents in Endometriosis: A Rat Model.

To evaluate the potential effect of Ankaferd Blood Stopper (ABS) and oxytocin (OT) in an experimental endometriosis model, 18 female Sprague Dawley rats were used in this study. The animals were divided randomly into three groups after surgical induction of endometriosis: group 1: control group (isotonic NaCl, 1 mL/kg/day, intramuscular, n=6); group 2: OT group (OT, 80 U/kg/day, intramuscular, n=6); group 3: ABS group (ABS, 1.5 mL/kg/day, intraperitoneal, n=6). Each group was treated for four weeks (two times per week). Volumes of endometriotic explants were measured in biopsy samples for histopathological analysis. Vascular endothelial growth factor (VEGF), monocyte chemotactic protein-1 (MCP-1), and tumour necrosis factor (TNF-α) levels were measured in plasma and peritoneal fluid. Endometriotic explant volumes were significantly decreased after OT administration (P<0.0001). The epithelial score was significantly decreased in both treatment groups compared to the control group (P<0.05). TUNEL immunohistochemistry showed more apoptotic changes in the endometriosis foci (gland epithelium and surrounding tissue) in the OT group than in the control group (P<0.05). The levels of VEGF, MCP-1, and TNF-α were significantly reduced in the OT group (P<0.05), whereas no significant changes in protein levels were found in the ABS-applied group. The results indicate that OT has greater potential as a therapeutic agent in experimentally induced peritoneal endometriosis, where ABS, which is a VEGF modulator, appears to act through different mechanisms to show its palliative effects on a rat model of peritoneal endometriosis.

Effects of Methylene Blue on Ovarian Torsion-Detorsion Injury in a Rat Model.

STUDY OBJECTIVES: Methylene blue (MB) is an antioxidant that ameliorates ischemia-reperfusion injury in several tissues. We analyzed the effects of MB as an inhibitor of torsion-detorsion injury in rat ovaries. METHODS: Rats were randomly divided into 5 groups. Group 1 was the sham group, in which only laparotomy was performed. Group 2 was the torsion group, with 3 hours of ischemia. Group 3 was the torsion + MB group, with 3 hours of ischemia after MB administration. Group 4 was the torsion-detorsion group, with 3 hours of ischemia and reperfusion. Finally, group 5 was the torsion-detorsion + MB group, with 3 hours of ischemia and MB administration before detorsion/reperfusion. Ovary injuries were histopathologically scored. Malondialdehyde (MDA) and total protein levels in ovarian tissues were determined, and long pentraxin-3 (PTX3) levels were measured in ovarian tissue using an enzyme-linked immunosorbent assay. RESULTS: In comparing group 4 with group 5 and group 2 with 3, histopathological parameters reflecting injury were significantly increased in groups 4 and 2. Group 3 generated increased MDA levels when compared with group 2 (P < .05). However, there was no significant difference between groups 2 and 3 in terms of plasma PTX3 levels. MDA and PTX3 levels decreased in group 5 in comparison with group 4 for MDA (P < .000) and PTX3 levels (P < .01). CONCLUSIONS: MB alleviated ischemia-reperfusion ovary injury in our experimental model.

Protective effect of oxytocin on a methotrexate-induced ovarian toxicity model.

PURPOSE: Although cancer predominantly affects people at older ages, a substantial number of patients, like breast cancer patients, are diagnosed before they have completed their families or even before giving birth. Furthermore, cytotoxic chemotherapy may be required in addition to treat cancer survivors. The present study was conducted to investigate the protective effect of oxytocin (OT) on methotrexate (MTX)-induced ovarian toxicity in rats. METHODS: Eighteen adult female Sprague-Dawley rats were used in the study. All rats were divided randomly into three groups. The control group (n = 6) received no treatment. The remaining 12 rats received a single dose of 20 mg/kg of MTX. Half of the rats (n = 6) were treated with 1 mg/kg/day of saline, and the other half (n = 6) were treated with 160 µg/kg/day of OT for 21 days. Then, blood samples were collected for biochemical analysis, and an ovariectomy was performed for histopathological examination. RESULTS: Plasma malondialdehyde (MDA) and transforming growth factor-ß (TGF-ß) levels were significantly lower in the MTX + OT group compared to the MTX + saline group (p = 0.000036 for MDA; p = 0.0044 for TGF-ß). AMH levels were also significantly higher in the MTX + OT group than in the MTX + saline group (p = 0.000036). The ovarian fibrosis percent was also notably lower in the MTX + OT group than in the MTX + saline group (p = 0.000036). CONCLUSION: On the basis of these findings, OT is a promising agent for ameliorating harmful effects of MTX on rat ovaries in an experimental model.

Granulocyte Colony-Stimulating Factor Prevents Ischemia/Reperfusion-Induced Ovarian Injury in Rats: Evaluation of Histological and Biochemical Parameters.

Granulocyte colony-stimulating factor (G-CSF) is a glycoprotein commonly used in the field of medicine to treat neutropenia. Granulocyte colony-stimulating factor has also crucial roles in ameliorating the ischemia/reperfusion (I/R) injury in particular tissues. In this study, we aimed to investigate the protective effect of G-CSF on ovarian damage in experimental ovarian I/R injury. Thirty adult female rats were used. Rats were separated randomly into 5 groups; Group 1: sham group (abdominal wall was opened and closed surgically), Group 2: torsion group with 3-hour ischemia using vascular clips. Group 3: torsion + G-CSF group with 3-hour ischemia 30 minutes after the administration intraperitoneal (i.p.) of 100 µg/kg of G-CSF. Group 4: torsion-detorsion group with 3 hour ischemia and 3 hour reperfusion. Group 5: torsion-detorsion + G-CSF group with 3 hour ischemia followed by 100 µg/kg of G-CSF i.p. administration 30 minutes prior to 3 hour of detorsion/reperfusion. Ovarian tissue damage was scored on histopathology. Ovarian tissue malondialdehyde (MDA) was measured biochemically. In comparison with the sham group, both the torsion and torsion-detorsion groups had significantly higher scores for follicular degeneration, vascular congestion, edema, hemorrhage, and leukocyte infiltration (P < .05). When compared group torsion-detorsion + G-CSF to group torsion-detorsion, parameters aforementioned significantly decreased in group torsion-detorsion + G-CSF (P < .05). Granulocyte colony-stimulating factor has also decreased MDA levels notably both in the torsion + G-CSF and torsion-detorsion + G-CSF groups (P < .05, P < .01). Our experimental study suggests that G-CSF can be a novel agent for the treatment of ovarian I/R injury.
