Minimally invasive vaginal hysterectomy using bipolar vessel sealing: preliminary experience with 500 cases.

The objective of our study was to evaluate surgical outcome of minimally invasive vaginal hysterectomy (MIVH), using the bipolar vessel sealing system (BVSS; BiClamp®). The design was a retrospective analysis (Canadian Task-force Classification II-3). The setting was a secondary care hospital. Records of patients who underwent vaginal hysterectomy for benign indications in our centre between November 2005 and March 2011 were reviewed. The demographic patients' data, indications for surgery, patient history with regard to previous surgery, duration of surgery, blood loss (postoperative hemoglobin drop '∆Hb'), perioperative complications, and length of inpatient stay were collected from the medical records. The intervention was vaginal hysterectomy using BVSS (BiClamp®). Results showed that the mean duration of surgery was 48.9 ± 15.3 min (95% CI, 49.2-52.5). The mean duration of hospital stay was 3.2 ± 1.2 days (95% CI, 2.8-3.2). The mean ∆Hb was 1.4 ± 1.8 g/dl. Overall, conversion to laparotomy was required in three cases (0.6%). Only one haemoperitoneum occurred (0.2%) and this is the only case who required blood transfusion. The main indication for VH was uterine prolapse in 52.0% (n = 260) of cases; uterine fibroids in 37.4% (n = 187); adenomyosis uteri in 4.2% (n = 21); cervical dysplasia in 22 patients (4.4%) and in 2% (n = 10) of patients, endometrial hyperplasia and other pathologies were the indications for VH. It was concluded that electrosurgical bipolar vessel sealing by (BiClamp®) can provide a safe and feasible alternative to sutures in vaginal hysterectomy, resulting in reduced operative time and blood loss, with acceptable surgical outcomes.

Chemically assisted dissection of tissues: an interesting support in abdominal myomectomy.

BACKGROUND: The aim of this study was to verify the efficacy of sodium-2-mercaptoethanesulfonate (mesna) in the chemical separation of tissues in abdominal myomectomies when used with the traditional mechanical separation techniques. STUDY DESIGN: In a prospective, randomized study, 58 women underwent abdominal myomectomy. In 29 of these, we used mesna for highlighting and separating tissues, and in the other 29 we used saline solution for the same purposes. The variables evaluated included the number of myomas removed, the volume of the biggest myoma, and the total volume of the myomas removed in every intervention. We also recorded operating time, the length of hospital stay, the degree of procedure difficulty, perioperative blood loss, operative complications, and cost. RESULTS: The operation was significantly shorter in the mesna group (p < 0.05) even though the volume and the number of myomas were larger. The degree of difficulty evaluated by the surgeon at the end of every operation was not significantly different in the two groups. The reduction in hemoglobin 24 hours after operation was significantly less in the patients treated with mesna (p = 0.006), but this difference was probably altered by the increase in hematocrit levels. CONCLUSIONS: Because of its ability as a chemical dissector, mesna may be a useful aid in this type of benign gynecologic operation. Larger studies to confirm this are needed.

Antenatal molecular diagnosis of X-linked ichthyosis by maternal serum screening for Down's syndrome.

A case of X-linked ichthyosis diagnosed antenatally by molecular analysis of fetal DNA is described. The diagnosis was made at 16 weeks gestation, following the finding of a maternal serum unconjugated estriol level lower than 0.1 MoM when performing a triple test. Fetal DNA was obtained from cultured amniocytes; two specific regions were amplified by polymerase chain reaction at 5' and 3' ends of the steroid sulfatase (STS) gene on Xp22.3 region. Analysis showed complete deletion of the STS gene on the distal tip of the X-chromosome short arm.
