Does the introduction of new technology change population demographics? Minimally invasive technologies and XXXX .

@entity1 @entity1478 @entity548
OBJECTIVE: To determine if the characteristics of @entity1 with @entity1478 changed as minimally invasive modalities for diagnosis and surgical treatment were integrated to our clinical practice. MATERIALS AND METHODS: The pathologic reports of all @entity1 diagnosed with @entity1478 in 1990 (220 @entity1 ) and 1996 (386 @entity1 ) were reviewed. The respective medical records were reviewed for anthropomorphic factors, bleeding pattern, diagnosis, and modality of surgical removal. Comparisons of dichotomous data and analysis of nominal variables with two or more categories were carried out with the chi(2) test. RESULTS: Differences in @entity1 characteristics or pattern of bleeding were minimal. In both groups, @entity1478 were more frequent in @entity1 with @entity548 , reaching almost 80%. Diagnostic and therapeutic modalities were significantly different in 1990 vs. 1996. Diagnosis by ultrasound increased fivefold (3.6 vs. 16.8%) and operative hysteroscopy increased threefold (6.4 vs. 19.7). The frequency of incidental diagnosis of @entity1478 at the time of hysterectomy decreased significantly. The most frequent modality of surgery done in 1990 was dilatation and curettage (44.6%), followed in frequency by endometrial biopsy and abdominal hysterectomy. In contrast, the most frequent modality in 1996 was hysteroscopic resection (36.8%), followed by dilatation and curettage (12.8%). CONCLUSIONS: The introduction of minimally invasive methods of diagnosis and treatment of @entity1478 has not changed the overall @entity1 population with this lesion.
