Tissue thermal damage caused by bipolar forceps can be reduced with a combination of plastic and metal
No full textBackground: We created a new 5-mm bipolar forceps. Thermo-insulating plastic was used for the creation of the jaws, while the metal conductor is buried deep inside the plastic. Methods: A porcine model was used in experimental testing against a standard metallic 5-mm bipolar forceps at three different wattage settings (20, 40, 60 W). Histological sections were evaluated by a pathologist who was blind to the wattage and instrument tested. Results: The new instrument was shown to cause statistically significant reduced thermal damage. In addition, its lateral thermal diffusion is superior to standard bipolar forceps. Conclusions: Thermo-insulating plastics can reduce thermal damage to tissue during electrosurgery
Endometriosis
No full textINTRODUCTION: Ectopic endometrial tissue is found in 1.5% to 6.2% of women of reproductive age, in up to 60% of those with dysmenorrhoea, and in up to 30% of women with subfertility, with a peak incidence at around 40 years of age. However, symptoms may not correlate with laparoscopic findings.METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of hormonal treatments given at diagnosis of endometriosis? What are the effects of hormonal treatments before surgery for endometriosis? What are the effects of non-hormonal medical treatments for endometriosis? What are the effects of surgical treatments for endometriosis? What are the effects of hormonal treatment after conservative surgery for endometriosis? What are the effects of hormonal treatment after oophorectomy (with or without hysterectomy) for endometriosis? What are the effects of treatments for ovarian endometrioma? We searched: Medline, Embase, The Cochrane Library, and other important databases up to December 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).RESULTS: We found 40 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: combined oral contraceptives, danazol, dydrogesterone, gestrinone, gonadorelin analogues, aromatase inhibitors, hormonal treatment before surgery, hormonal treatment, laparoscopic cystectomy, laparoscopic removal of endometriotic deposits (alone or with uterine nerve ablation), laparoscopic removal plus presacral neurectomy, laparoscopic uterine nerve ablation, non-steroidal anti-inflammatory drugs, presacral neurectomy alone, and progestogens other than dydrogesterone
Inibitori dell’aromatasi nel trattamento dell’endometriosi profonda
No full textRecent case reports and pilot studies suggested that aromatase inhibitors might be effective in treating pain symptoms related to the presence of endometriosis. We present the case of a 32-year-old woman who suffered dysmenorrhea, dyspareunia, chronic pelvic pain, and dyschezia caused by rectovaginal endometriosis. Pain symptoms recurred after treatment with the oral contraceptive pill; the patient refused surgery.Therefore a double-drug regimen including letrozole (2.5 mg/day) and norethisterone acetate (2.5 mg/day) was offered to the patient. The scheduled length of treatment was six months. This double-drug regimen determined a quick and significant improvement in all pain symptoms. During treatment, the patient complained mild arthralgia. After the interruption of treatment, pain symptoms quickly recurred and at 6-month follow-up their intensity was similar to baseline values. Operative laparoscopy was performed, the presence of rectovaginal endometriosis was confirmed and all visible endometriotic lesions were excised. Aromatase inhibitors might be offered when pain symptoms caused by endometriosis persist during the administration of other hormonal therapies and the patient refuses surgery. However, women must be informed that these drugs determine only a temporary relief of pain symptoms and might cause adverse effects (such as arthralgia)
Aromatase Inhibitors in the Treatment of Endometriosis
No full textCurrent treatment of endometriosis is mainly based on surgery and ovarian suppressive agents. In the last 10 years, it has been demonstrated that aromatase P450, a key enzyme for estrogen biosynthesis, may have a pathogenic role in endometriosis because it is aberrantly expressed in endometriotic implants and in eutopic endometrium of women with endometriosis. Therefore, inhibition of aromatase activity may represent a new therapeutic option for endometriosis. Case reports and observational studies have shown that pain symptoms caused by endometriosis quickly improve after administration of aromatase inhibitors. Limited data are available on the long-term course of pain symptoms after completion of treatment with aromatase inhibitors; however, some recent studies suggest that symptoms may recur at short-term follow-up. A range of results are reported on the effects of aromatase inhibitors on endometriotic lesions, with some authors describing improvements and other authors reporting persistence of pelvic lesions at second-look laparoscopy after treatment. No severe adverse effect has been reported during treatment with aromatase inhibitors both in pre- and postmenopausal women. On the basis of the available data, administration of aromatase inhibitors should now be offered only to the small number of women who have severe pain despite previous surgical and hormonal therapies. Further research in the form of randomized controlled trials will be required before recommending the routine use of these agents
