RESUMO
AIM: The study objective was to compare intraoperative and early postoperative outcomes among patients who underwent hysterectomy via transvaginal natural orifice transluminal endoscopic surgery (and single-port lararoscopy for presumed benign gynecologic disorders). METHODS: We retrospectively reviewed 40 patients who underwent single-port laparoscopic hysterectomy and 20 patients who underwent hysterectomy via natural orifice transluminal endoscopic surgery. Patients' age, body mass index, history of previous delivery and surgery, total operation time (from skin incision to closure), intraoperative and postoperative complications conversion to another surgical procedure, drop of hemoglobin level, postoperative pain at 1 and 18 h, average hospital stay, and clinical outcomes were analyzed. RESULTS: Hysterectomy via transvaginal natural orifice transluminal endoscopic surgery was superior to single-port hysterectomy concerning the length of hospitalization (p < 0.001) and visual analog scale at 1 h (p = 0.024) and 18 h (p < 0.001). In transvaginal natural orifice transluminal endoscopic group, postoperative complications were lower than single-port laparoscopy group (p = 0.023). In transvaginal natural orifice transluminal endoscopy, group conversion to a standard vaginal hysterectomy occurred in two cases (10%). Four patients in the single-port laparoscopic hysterectomy group had umbilical herniation, three had port-site infections, and two patients had vaginal cuff hematoma. These patients required rehospitalization. CONCLUSIONS: Despite hysterectomy via transvaginal natural orifice transluminal surgery has not yet found its place in routine practice in gynecology departments, it could be a prominent alternative approach to other minimally invasive surgical procedures in selected patients with many advantages including lesser pain and lower complication rates compared with single-port laparoscopic hysterectomy.

OBJECTIVE: To determine the possible underlying cause of a false-positive first or second trimester biochemical Down syndrome screening test result by means of second trimester amniotic fluid cytokine level analysis. METHODS: A total of 74 consecutive patients undergoing amniocentesis for karyotype analysis at 16-20 weeks' gestation were included in this prospective age-matched case-control study. The study group (n=38) had abnormal first or second trimester screening test results and normal karyotype results, while controls (n=36) included those admitted for genetic amniocentesis for other reasons who had normal first or second trimester screening test and normal karyotype results. Four markers [interleukin (IL)-6, IL-8, tumor necrosis factor (TNF)-alpha, and ischemia-modified albumin (IMA)] were studied in amniotic fluid. RESULTS: The mean age of the women in the study and control groups was 34.0+/-5.6 and 33.6+/-7.2 years, respectively. The women in the study and control groups had similar clinical and laboratory characteristics. The mean amniotic fluid IL-6 (414.84+/-83.96 vs. 343.02+/-110.59, p=0.002) and IL-8 (377.61+/-243.31 vs. 261.90+/-201.29, p=0.029), TNF-alpha (24.91+/-5.78 vs. 21.60+/-5.55, p=0.014), and IMA (1.19+/- 0.10 vs. 1.05+/-0.12, p<0.001) values were significantly increased in the study group when compared to controls. CONCLUSION: The higher amniotic fluid cytokine and ischemia-modified albumin levels in patients with false-positive first or second trimester biochemical Down syndrome screening test may result from subclinical fetal membrane inflammation and/or ischemia.
