ABSTRACT

Objective:To investigate the significance of clinical factors combined with transvaginal ultrasound and contrast-enhanced ultrasound(CEUS) in guiding the choice of treatment plan for cesarean scar pregnancy(CSP).Methods:The clinical and transvaginal ultrasound and CEUS data of 120 patients with CSP from January 2016 to June 2021 in the First People′s Hospital of Foshan were retrospectively analyzed, and they were divided into ultrasound-guided curettage/ hysteroscopic group (Group A, 91 cases) and laparoscopic group (Group B, 29 cases) according to treatment option, and the differences in clinical and ultrasound factors between the two groups were compared, and to determine the relevant clinical and ultrasound indicators for the choice of treatment option.Results:There were statistical differences between the 2 groups in comparison of whether the gestational sac/mass protruded toward the plasma membrane, gestational sac/mass diameter, the main blood supply site of the gestational sac/mass, the site of the chorion/early placenta and scar thickness (all P<0.05). Logistic regression analysis indicated that CEUS showing major blood supply site of the gestational sac/mass ( OR=6.029, P=0.003) and uterine scar thickness ( OR=12.998, P=0.002) were independent risk factors for minimally invasive surgery for CSP. Conclusions:Ultrasound combined with clinical factors have a certain value in the selection of treatment options for CPS, and the thickness of the uterine scar and the main blood supply site of the gestational sac/mass showed in CEUS may be key factors affecting the minimally invasive surgical treatment of CSP.

ABSTRACT

Objective:To construct and evaluate a parotid mass malignancy risk model based on ultrasound image characteristics and clinical features of parotid masses.Methods:Ultrasound images and clinical features of 214 patients with parotid masses in the First People′s Hospital of Foshan were retrospectively collected from June 2018 to August 2020. The pathology results were taken as the golden standard. All the clinical features and ultrasound image features were first screened using regression analysis, and then the screened features were used to build a prediction model.Results:Malignant tumors of the parotid gland appeared on ultrasound as hypoechoic solid masses with or without abnormal cervicofacial lymph nodes with poorly defined borders and irregular morphology. Multifactorial analysis showed that facial nerve function, cervicofacial lymph node abnormalities, maximum diameter, morphology and borders of the mass were independent predictors of the risk of malignant parotid masses. A Nomogram prediction model was established using the above 5 indicators, and the results showed a concordance index(C-index) of 0.896 (95% CI=0.834-0.958) for Nomogram. The standard curve showed good agreement between the predictive effect of Nomogram and the actual situation of benign and malignant parotid swellings, with an internally validated C-index of 0.878. Conclusions:Ultrasound is of great value in identifying benign and malignant parotid tumors. The Nomogram model using ultrasound image features and clinical characteristics can assess the biocharacteristics of parotid masses, and the model shows high accuracy in predicting the risk of malignancy of parotid masses.

ABSTRACT

Objective:To investigate the feasibility of transperineal ultrasound in quantitative assessment of posterior compartment prolapse among Chinese women.Methods:The prospective multicenter study enrolled 485 women between January 2017 and January 2019. All patients underwent a standard clinical interview, pelvic organ prolapse quantification (POP-Q) examination and transperineal ultrasound examination. Volume data of transperineal ultrasound examinations were obtained at rest and in maximal Valsalva maneuver.Results:The higher POP-Q stage of posterior compartment, the lower rectal ampulla position in maximal Valsalva maneuver (POP-Q stage=0 vs POP-Q stage=1, P<0.001; POP-Q stage=1 vs POP-Q stage≥2, P<0.001), and the greater rectal ampulla hypermobility (POP-Q stage=0 vs POP-Q stage=1, P<0.001; POP-Q stage=1 vs POP-Q stage≥ 2, P=0.007). The rectal ampulla position at rest and in maximal Valsalva maneuver and rectocele depth were correlated with prolapse symptoms ( r=-0.200, P<0.001; r=-0.252, P<0.001; r=0.086, P=0.045). The corresponding cut-off values of rectal ampulla position in maximal Valsalva in diagnosing posterior compartment prolapse (POP-Q stage ≥1) and clinical significant posterior compartment prolapse (POP-Q stage ≥2) were 7.32 mm below the symphysis pubis and 12 mm below the symphysis pubis, respectively, with the area under the ROC curve as 0.75 and 0.85, respectively. Conclusions:The ultrasonic measurements by transperineal ultrasound is significantly associated with POP-Q examination in posterior compartment, and it is demonstrated as a useful tool in quantitative assessment of the severity of posterior compartment prolapse.

ABSTRACT

Objective:To investigate the association between levator hiatus area, pelvic organ prolapse quantification (POP-Q) examination and prolapse symptoms.Methods:The prospective multicenter study enrolled 996 female patients between January 2017 and January 2019. All enrolled patients underwent a standard clinical interview, POP-Q examination and transperineal ultrasound examination. Volume data of pelvic floor ultrasound examinations were obtained at rest, during contraction and during maximal Valsalva maneuver. The association between levator hiatus area, POP-Q examination and prolapse symptoms was analyzed. The performance of levator hiatus area on maximal Valsalva for assessing significant POP(POP-Q stage≥2) and prolapse symptoms were also evaluated.Results:There were significant differences of levator hiatus area at rest, during contraction and during maximal Valsalva among patients with different POP-Q stages (all P<0.001). Levator hiatus area during maximal Valsalva showed the highest correlation with abdominal dragging sensation ( r=0.277, P<0.001). The area under the ROC curve (AUC) of levator hiatus area during maximal Valsalva for significant POP (POP-Q stage≥2) was significantly higher than that for prolapse symptoms (AUC: 0.77 vs 0.69, P<0.001). Conclusions:Levator hiatus area on transperineal has moderate correlation with POP-Q examination and their association is stronger than the correlation between ultrasound findings and prolapse symptoms.
