Sharp Versus Electric Suction Curettage in Gynecologic Patients Undergoing Evaluation for Abnormal Uterine Bleeding.

STUDY OBJECTIVE: Suction curettage is preferred over sharp curettage in obstetric settings. We compare the quality of operative tissue sampling between sharp curettage and suction curettage using electric vacuum aspiration for nonobstetric abnormal uterine bleeding in reproductive-aged women. DESIGN: A retrospective cohort study. SETTING: Community hospital in Long Island, New York. PATIENTS: Women ages 21 to 45 years (n = 257) who underwent operative curettage procedure for nonobstetric abnormal uterine bleeding. INTERVENTIONS: Independent ratings of specimens from suction curettage using electric vacuum aspiration and sharp curettage by 2 pathologists blinded to method of tissue collection. MEASUREMENTS AND MAIN RESULTS: The primary outcome was percentage of organized tissue, indicative of a higher-quality pathology specimen. Specimens obtained by electric suction curettage (p <.001) had a significantly higher percentage of organized tissue (M = 66.28, SD = 20.33) than sharp curettage (M = 55.51, SD = 24.17). There were no differences between the curettage groups for operative time, blood loss, intraoperative complications, or pathology diagnosis. CONCLUSION: Specimens obtained with suction curettage contained more organized tissue with similar pathologist satisfaction and confidence scores than sharp curettage. We suggest clinicians consider electric suction curettage in the diagnostic workup of abnormal uterine bleeding in reproductive-aged women. In addition, patient-centered benefits include no increase in operative time, blood loss, or complication rate compared with sharp curettage.

Monomorphous angiocentric glioma: a distinctive epileptogenic neoplasm with features of infiltrating astrocytoma and ependymoma.

We present 8 examples of a neoplasm with features of both astrocytoma and ependymoma that may represent a distinct clinicopathologic entity. The cerebral hemispheric tumors occurred in patients that were 3, 4, 12, 14, 15, 26, 30, and 37 years of age. All presented with seizures that, with the exception of 2, began in childhood. Magnetic resonance imaging studies showed ill-defined, T2-hyperintense, generally noncontrast-enhancing lesions that, although centered on the cortex or amygdala, extended into the underlying white matter for a short distance. Histologically, the variably infiltrative tumors were distinctively angiocentric with well-developed perivascular pseudorosettes in some cases. Longitudinal and/or circumferential orientations of perivascular cells were common also. The cells were uniform in their cytologic features from case to case and were bipolar in all but one case. A glial nature was inferred from immunoreactivity for GFAP, and ependymal differentiation was suggested by positivity for EMA in three cases and ultrastructural features in one. Overall, the tumors were biologically indolent except for one that recurred and ultimately proved fatal.
