- Abstract
Objective: The aim of the present study was to illustrate the outcomes of abnormally invasive placenta (AIP) cases managed in three leading centers in Lebanon., Methods: We conducted a retrospective multicenter cohort study. Patients managed conservatively (cesarean delivery with successful placental separation) or radically (cesarean hysterectomy) were included in the study. Data included patient characteristics, surgical outcomes (blood loss, operative time, transfusion, partial bladder resection), maternal outcomes (death, length of stay, ICU admission, postoperative hemoglobin level) and neonatal outcomes (Apgar score, neonatal weight, admission to neonatal intensive care unit, neonatal death)., Results: The study included 189 patients. In the radical treatment subgroup (141/189), patients were para 3 and delivered at 34 4/7 weeks in average, bled 1.5 L and were transfused with three packed red blood cells, with operative time averaging 160 min. A total of 36% were admitted to the ICU and patients stayed on average for 1 week despite partial bladder resection in 19% of cases. Unscheduled radical delivery occurred at a lower gestational age, was associated with more blood loss, higher rate and volume of transfusion, and risk of maternal and neonatal death. In addition, patients delivered in an unscheduled fashion experienced higher rates of partial bladder resection and longer interventions. In the conservative treatment subgroup, on average patients were para 2 and delivered at 36 weeks, bled 800 mL on average with low rates of transfusion (35%) and ICU admission (22.9%). With regard to neonatal outcomes, the average neonatal birth weight was 2.4 kg in the radical subgroup and 2.5 kg in the conservative subgroup. Neonatal death occurred in 5.4% of cases requiring radical management while it occurred in 2% of patients treated conservatively., Conclusion: Through their multidisciplinary approach, the three centers demonstrated that management of AIP in Lebanon has led to excellent outcomes with no maternal mortality occurring in scheduled radical treatment. By comparison of the three leading centers, pitfalls in each center were identified and addressed., (© 2024 International Federation of Gynecology and Obstetrics.)

- Abstract
Objective: To evaluate the efficiency of the Robson classification as an internal clinical audit and feedback of the high rate of cesarean delivery at Hotel Dieu de France, a tertiary referral hospital., Methods: A pre-post study was conducted, with a retrospective approach in 2018 and 2019, identified as the pre-period (before the implementation of the Robson classification), and with a prospective approach in 2020 and 2021, labeled the post-period., Results: The total number of deliveries during the study period was 2560; 1305 patients were included in the pre-period and 1255 patients delivered in the post-period. No significant differences between the two groups were found. No significant difference was found in the overall rate of cesarean delivery between the first and second periods (57.86% vs 56.72%; P = 0.2). However, a significant decrease in the absolute contribution of groups 3 and 4 (multiparous women without a previous uterine scar with a single cephalic pregnancy, ≥37 weeks of gestation, with spontaneous labor or induced labor) in the overall rate of cesarean delivery was remarked (P = 0.02 and 0.01, respectively)., Conclusion: The Robson classification seems to be appropriate to monitor and audit the rate of cesarean delivery, but not sufficient to decrease the rate and change the practice., (© 2022 International Federation of Gynecology and Obstetrics.)

- Abstract
Objective: To evaluate the cesarean section rate using the Robson Classification for the first time in Lebanon, at Hôtel-Dieu de France University Hospital, a tertiary referral center in Beirut., Methods: Routine medical record data that included all live births from January 1, 2018 to September 30, 2020 was investigated. The overall cesarean section rate was recorded, and the size, cesarean section rate, and absolute and relative contributions were calculated within each group., Results: The overall cesarean section rate was 56.8%. The highest relative contribution to this rate came from Robson groups 5, 2 and 10, respectively. A decrease in cesarean section rate was noted in 2020 among women admitted for induction of labor (groups 2 and 4) following the implementation of new department policies and the restrictions caused by the coronavirus disease 2019 pandemic., Conclusion: More than 50% of the deliveries in our department were by cesarean sections (CS). Strategies to reduce this rate should include stricter departmental policies for avoidance of unindicated primary CS and raising practitioners' and patients' awareness about trial of labor after cesarean section., (© 2021 International Federation of Gynecology and Obstetrics.)

- Abstract
We present the case of a 30-year-old lady who underwent a core needle biopsy for a BIRADS 4 lesion of her left breast and was diagnosed as having a cellular fibroadenoma. The final diagnosis after excision returned to be a periductal stromal tumor (PST). An extremely rare entity, the PST is actually classified as a subtype of phyllodes tumor, with specific criteria that are only found upon histological examination of the specimen. Care should be taken when considering the diagnosis of fibroadenoma based only on clinical, radiological, and biopsy findings. Any nonclassical, clinical, or radiological findings should prompt a wide excision. Prognosis is generally good when clear margins are obtained and in the absence of malignant heterologous elements., (© 2021 Wiley Periodicals LLC.)

- Abstract
Breast conservation rate is being increasingly used nowadays as a marker of breast cancer care among hospitals. Searching for the ideal technique to predict the feasibility of BCS is ongoing. For this matter, the preoperative MRIs of 169 patients operated with radical or conservative surgery were reviewed. We estimated the tumor volume (TV) and breast volume (BV) on enhanced 3D-MRI and compared the tumor-to-breast volume ratio (TV/BV) in both groups. The mean ratio was 9.5% in the mastectomy group and 1.7% in the BCS group. A tumor-to-breast volume ratio less than 4% seemed to favor the adoption of a conservative option. Our data suggest that preoperative 3D-MRI can orient the surgical approach by assessing the TV/BV ratio, increasing lumpectomy rates with clear margins and good cosmetic outcome., (© 2020 Wiley Periodicals LLC.)

- Abstract
To evaluate the diagnostic value of diffusion-weighted imaging (DWI) in combination with conventional MRI in predicting metastatic axillary lymph nodes (ALN) in breast cancer (BC). We reviewed pathological findings and clinical breast MRI examinations of 169 patients with invasive BC who were evaluated at the Hôtel-Dieu de France Hospital in 2009-2015. Morphological parameters and apparent diffusion coefficient (ADC) value were compared with pathological nodal status. Independent t-test/chi-square test and a Pearson correlation analysis were used. With pathological diagnosis as reference, MRI-based interpretations were 87.5% specific and 70.3% sensitive. On conventional MRI, the round shape of lymph nodes (LNs), loss of fatty hilum, irregular margins and hypo-intensity/heterogeneous intensity on T2-weighted sequence were statistically significantly different between metastatic and nonmetastatic groups (P < .001, each). Mean size of metastatic ALN was larger compared with negative ALN (13.9 mm vs. 10.9 mm, P < .001). LNs ≥ 12 mm were associated with higher risk of metastasis (P < .001). ADC value was not significantly different between both groups (P = .862). Conventional MRI using the ALN shape, signal intensity in T2-weighted sequences, loss of fatty hilum, regularity of the margins and size of the LNs can evaluate the axilla with high specificity. ADC value could not be used as a reliable parameter., (© 2020 Wiley Periodicals LLC.)

- Abstract
Objective: To report the outcomes of women with placenta percreta who were surgically treated by a specialized technique based on gynecologic oncology experience, and to demonstrate its safety in preventing ureteral lesions and reducing blood loss., Methods: In the present retrospective study, data from patients with placenta percreta radically treated at Hôtel-Dieu de France, Beirut, Lebanon, between December 2012 and January 2017 were reviewed. Demographic, pathology, and delivery data, medical history, per-operative and postoperative information, and neonatal data were assessed. Operative and postoperative outcomes were compared between emergency and scheduled cases., Results: Data from 35 patients were reviewed. Median gestational age at delivery was 34 weeks. Cesarean hysterectomy was scheduled in 20 (60%) cases. No ureteral lesions were noted. The median estimated blood loss was 1 L and a median of 3 units of red blood cells units was transfused. Emergency and scheduled cases presented comparable estimated blood loss, intra-operative transfusion, bladder injury incidence, and surgery duration (all P>0.05). The mean delivery weight was 2100 g; admission to the neonatal intensive care unit was needed for 30 (86%) neonates., Conclusion: The surgical technique developed for placenta percreta was found to be effective (operative and postoperative outcomes) and safe (prevention of ureteral lesions)., (© 2017 International Federation of Gynecology and Obstetrics.)

- Abstract
Purpose: To study the distribution of breast mammogram density in Lebanese women and correlate it with breast cancer (BC) incidence., Methods: Data from 1,049 women who had screening or diagnostic mammography were retrospectively reviewed. Age, menopausal status, contraceptives or hormonal replacement therapy (HRT), parity, breastfeeding, history of BC, breast mammogram density, and final BI-RADS assessment were collected. Breast density was analyzed in each age category and compared according to factors that could influence breast density and BC incidence., Results: 120 (11.4%) patients had BC personal history with radiation and/or chemotherapy; 66 patients were postmenopausal under HRT. Mean age was 52.58 ± 11.90 years. 76.4% of the patients (30-39 years) had dense breasts. Parity, age, and menopausal status were correlated to breast density whereas breastfeeding and personal/family history of BC and HRT were not. In multivariate analysis, it was shown that the risk of breast cancer significantly increases 3.3% with age ( P = 0.005), 2.5 times in case of menopause ( P = 0.004), and 1.4 times when breast density increases ( P = 0.014)., Conclusion: Breast density distribution in Lebanon is similar to the western society. Similarly to other studies, it was shown that high breast density was statistically related to breast cancer, especially in older and menopausal women.
