RESUMO
BACKGROUND: The ideal vaginoplasty must be successful functionally as well as have a natural appearance, and also must retain its functionality and appearance over the long term. Conventional vaginoplasty techniques have functional limitations and are associated with recurrent complications, but rectosigmoid vaginoplasty is known to have a high satisfaction rate due to its functional similarity with the vagina. We conducted the present study to assess the usability of rectosigmoid vaginoplasty over the course of long-term follow-up. METHODS: From March 1992 to February 2014, 84 patients were treated with rectosigmoid vaginoplasty; 44 had gender identity disorder, 29 had vaginal agenesis, 8 had female pseudohermaphroditism, and 3 had gynecologic malignancies after radical pelvic surgery. This retrospective study was based on a review of the patients' records, clinical examinations, complications, and questionnaires about appearance, function, and sexual intercourse. RESULTS: All patients who underwent rectosigmoid vaginoplasty were discharged within 2 weeks without surgical flap loss. The early complications were partial flap necrosis, difficulty in defecation, mucous hypersecretion, and postoperative ileus. The late complications were vaginal introitus contracture, vaginal prolapse, and difficulty in urination. The mean length and diameter of the neovagina 3.4 years after rectosigmoid vaginoplasty were 13.2 cm and 3.8 cm, respectively. On questionnaires about satisfaction, 70% of patients reported excellent satisfaction, 11% good, 12% fair, and 7% poor. CONCLUSIONS: Rectosigmoid vaginoplasty is useful, safe, and well-accepted operative method with good functional and cosmetic results, such as natural lubrication and adequate vaginal length and width obtained without requiring the use of a dilator.
RESUMO
BACKGROUND: Acute pulmonary thromboembolism (APTE) is a life-threatening condition, often manifesting with chest pain, dyspnea, and increased cardiac biomarkers including cardiac troponin I (CTI) and D-dimer. Therefore, APTE is often misdiagnosed with classical non-ST elevation myocardial infarction (NSTEMI), resulting in unnecessary coronary interventions and a delay of therapy. OBJECTIVES: Our aim was to distinguish APTE from NSTEMI based on CTI and D-dimer levels. METHODS: Complete clinical and laboratory data sets from APTE patients (n = 123) were compared with matched NSTEMI patients (n = 123) who presented with chest pain. The APTE diagnosis was confirmed by chest tomography, angiography, or radionuclide ventilation-perfusion scan, while NSTEMI was established by clinical symptoms, cardiac biomarkers, and coronary angiography. Clinical characteristics, CTI (initial and peak), and D-dimer levels at presentation were retrospectively analyzed. RESULTS: The clinical characteristics were not different between APTE and NSTEMI patients. However, significantly lower initial CTI (0.2 ± 0.5 vs. 4.4 ± 9.5 ng/ml) and peak CTI (0.7 ± 2.7 vs. 17.1 ± 20.4 ng/ml), but higher initial D-dimer (9.8 ± 9.4 vs. 1.6 ± 3.6 ng/ml), distinguished APTE from NSTEMI. By receiver operating characteristic curve analysis, the cutoff values for initial CTI, peak CTI, and D-dimer were 0.25, 0.98, and 3.18 ng/ml, respectively. CONCLUSION: Patients with APTE exhibited lower initial and peak CTI but higher D-dimer levels than NSTEMI patients. Assessing cardiac biomarkers is useful for differentiating APTE from NSTEMI. Further large randomized biomarker studies are urgently needed to facilitate a better APTE diagnosis since clinical characteristics are not particularly helpful.
