INTRODUCTION Chylous ascites is a rare form of ascites that results from accumulated lymph fluid in the peritoneal cavity caused by blocked or disrupted lymph flow through the major lymphatic channels. In the present study, our aim was to analyze the incidence, risk factors, diagnostic evaluation and management of chylous ascites after lymphadenectomy in gynecologic malignancies. METHODS A total of 458 patients who had undergone staging surgery for gynecologic malignancies at our institution between January 2010 and December 2013 were retrospectively reviewed. After the exclusion criteria were applied, 399 patients were divided into 2 groups based on the presence (n = 36) or absence (n = 363) of chylous ascites. RESULTS Among the 399 patients, 36 (9%) developed chylous ascites. The median time to onset was 4 days (range, 2-7 days). The analysis of the various features of lymphadenectomy showed that the number of para-aortic lymph nodes (PALNs) removed was significantly greater in the patients with chylous ascites (p < 0.001). A cut-off value of >14 PALNs was a good predictor of chylous ascites. In all patients, chylous ascites resolved with conservative management. CONCLUSIONS Postoperative chylous ascites was strongly associated with the number of harvested PALNs. According to our findings, we suggest that conservative treatment should be the first step in managing patients with chylous ascites. Using an abdominal drain after surgery seems to be an effective diagnostic tool and treatment method for chylous ascites.

OBJECTIVE Para-aortic lymph node dissemination in endometrioid endometrial cancer is uncommon, and systematic para-aortic lymph node dissection increases morbidity. The purpose of this study was to identify a subgroup of endometrioid endometrial cancer patients who did not require para-aortic lymphadenectomy. STUDY DESIGN All patients who had undergone surgery for endometrioid endometrial cancer between 1 January 1995 and 31 December 2012 were retrospectively reviewed. Patients with higher risk factors for nodal metastasis and inadequate lymphadenectomy were excluded. Para-aortic lymph node dissemination was defined as nodal metastasis when pelvic and para-aortic lymph node dissection was performed, when para-aortic lymph node recurrence occurred after negative para-aortic lymph node dissection or when para-aortic lymph node dissection was not performed. Multivariate logistic regression models were used to identify the pathological features as predictors for para-aortic lymphatic dissemination. RESULTS A total of 827 patients were assessed, 516 (62.4%) of whom underwent pelvic and para-aortic lymph node dissection. Sixty-seven (13%) patients (37 with only pelvic, 26 with pelvic and para-aortic, and 4 with only para-aortic metastasis) had positive lymph nodes in the pelvic and para-aortic lymph node dissection group. Multivariate analysis confirmed positive pelvic nodes (odds ratio 20.58; p<0.001) and lymphovascular space invasion (odds ratio 8.10; p=0.022) as independent predictors of para-aortic lymphatic dissemination. When these two factors were absent (in 83% of patients), the predicted probability of para-aortic lymph node metastasis was 0.1%. CONCLUSION Positive pelvic nodes and lymphovascular space invasion are highly associated with para-aortic lymph node metastasis. These markers may be useful for identifying those patients who require para-aortic lymph node dissection.

Purpose The purpose of this study is to evaluate the prognostic role of preoperative neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) and the need for para-aortic lymphadectomy in patients with primary fallopian tube carcinoma (PFTC). Materials and Methods Ninety-one patients with a diagnosis of PFTC were identified through the gynecologic oncology service database of six academic centers. Clinicopathological, surgical, and complete blood count data were collected. Results In univariate analysis, advanced stage, suboptimal surgery, and NLR > 2.7 were significant prognostic factors for progression-free survival, whereas in multivariate analysis, only advanced stage and suboptimal surgery were significant. In addition, in univariate analysis, cancer antigen 125 ≥ 35 U/mL, ascites, advanced stage, suboptimal surgery, NLR > 2.7, PLR > 233.3, platelet count ≥ 400,000 cells/mm3, staging type, and histological subtype were significant prognostic factors for overall survival (OS); however, in multivariate analysis, only advanced stage, suboptimal surgery, NLR > 2.7, and staging type were significant. Inclusion of pelvic and para-aortic lymphadenectomy in surgery showed significant association with longer OS, with a mean and median OS of 42.0 months and 35.5 months (range, 22 to 78 months), respectively, vs. 33.5 months and 27.5 months (range, 14 to 76 months), respectively, for patients who underwent surgery without para-aortic lymphadenectomy (hazard ratio, 3.1; 95% confidence interval, 1.4 to 5.7; p=0.002). Conclusion NLR (in both univariate and multivariate analysis) and PLR (only in univariate analysis) were prognostic factors in PFTC. NLR and PLR are inexpensive and easy tests to perform. In addition, patients with PFTC who underwent bilateral pelvic and para-aortic lymphadenectomy had longer OS.

[Purpose] The aim of this study was to evaluate whether the effect of pelvic floor exercises on pelvic floor muscle strength could be detected via ultrasonography in patients with urinary incontinence. [Subjects and Methods] Of 282 incontinent patients, 116 participated in the study and were randomly divided into a pelvic floor muscle training (n=65) group or control group (n=51). The pelvic floor muscle training group was given pelvic floor exercise training for 12 weeks. Both groups were evaluated at the beginning of the study and after 12 weeks. Abdominal ultrasonography measurements in transverse and longitudinal planes, the PERFECT scheme, perineometric evaluation, the stop test, the stress test, and the pad test were used to assess pelvic floor muscle strength in all cases. [Results] After training, the PERFECT, perineometry and transabdominal ultrasonography measurements were found to be significantly improved, and the stop test and pad test results were significantly decreased in the pelvic floor muscle training group, whereas no difference was observed in the control group. There was a positive correlation between the PERFECT force measurement scale and ultrasonography force measurement scale before and after the intervention in the control and pelvic floor muscle training groups (r=0.632 and r=0.642, respectively). [Conclusion] Ultrasonography can be used as a noninvasive method to identify the change in pelvic floor muscle strength with exercise training.

Abstract Objectives: To examine the effect of antenatal betamethasone administration on Doppler parameters of fetal and uteroplacental circulation. Methods: Seventy-six singleton pregnancies that received betamethasone therapy were prospectively evaluated. Doppler measurements of pulsatility indices (PI) in fetal umbilical artery (UA), middle cerebral artery (MCA), ductus venosus and maternal uterine arteries were performed before (0 h) and 24, 48, 72 and 96 h after the first dose of betamethasone. Women with positive end-diastolic flow (EDF) in UA and those with absent or reversed EDF in UA were evaluated separately. Results: Fifty-two women with EDF in UA and 24 women with absent or reversed flow in UA were examined. Administration of maternal betamethasone was followed by a significant decrease in the PI of the MCA at 24 h (P<0.05). Additionally, return of absent to positive, reversed to absent or from reversed to positive diastolic flow in UA was detected within 24 h in 19 (79.2%) fetuses with absent or reversed UA-EDF. All alterations were transient and maintained up to 72 h. Conclusions: Antenatal administration of betamethasone is associated with significant but transient changes in the fetal blood flow. Hence, intensive surveillance of fetuses with Doppler ultrasonography is warranted following betamethasone therapy.

Abstract Objective: To determine whether urea and creatinine measurements in vaginal fluid could be used to diagnose preterm premature rupture of membranes (PPROM) and predict delivery interval after PPROM. Methods: A prospective study conducted with 100 pregnant women with PPROM and 100 healthy pregnant women between 24 + 0 and 36 + 6 gestational weeks. All patients underwent sampling for urea and creatinine concentrations in vaginal fluid at the time of admission. Receiver operator curve analysis was used to determine the cutoff values for the presence of PPROM and delivery within 48 h after PPROM. Results: In multivariate logistic regression analysis, vaginal fluid urea and creatinine levels were found to be significant predictors of PPROM (p < 0.001 and p < 0.001, respectively) and delivery within 48 h after PPROM (p = 0.012 and p = 0.017, respectively). The optimal cutoff values for the diagnosis of PPROM were >6.7 mg/dl for urea and >0.12 mg/dl for creatinine. The optimal cutoff values for the detection of delivery within 48 h were >19.4 mg/dl for urea and >0.23 mg/dl for creatinine. Conclusion: Measurement of urea and creatinine levels in vaginal fluid is a rapid and reliable test for diagnosing and also for predicting delivery interval after PPROM.
