腹主动脉球囊预置术与髂内动脉球囊预置术在植入型凶险性前置胎盘治疗中的比较研究

目的:比较研究腹主动脉球囊预置术与髂内动脉球囊预置术在植入型凶险性前置胎盘治疗中的临床疗效。方法:选择2014年1月至2015年4月住院治疗的植入型凶险性前置胎盘患者64例,随机分为两组,择期剖宫产术前行腹主动脉球囊置管32例(腹主动脉组)和双侧髂内动脉球囊置管32例(髂内动脉组),观察比较两组孕妇术中、术后情况及新生儿出生和婴儿期生长发育情况。结果:两组患者在手术时间、术中出血量、术后最高体温、输血率、子宫切除率、住院时间、球囊预置术后穿刺部位出血率、感觉障碍发生率、新生儿Apgar评分、新生儿身高、出生体质量等方面比较,差异均无统计学意义(P0.05);而腹主动脉组球囊预置时间、透视时间、放射剂量均显著低于髂内动脉组(P0.05)。术后1年内随访,两组婴儿在42天、3个月、6个月、1年的体质量及身高情况比较,差异均无统计学意义(P0.05)。结论:腹主动脉球囊预置术与髂内动脉球囊预置术在植入型凶险性前置胎盘的治疗中均能安全、有效减少术中出血。而腹主动脉球囊预置术X线暴露时间更短、预判效果无需造影剂,对母胎保护性更强,可在临床推广。     

Laparoscopic Morcellator-Related Complications

Morcellation at laparoscopy is a commonly used minimally invasive method to extract bulky tissue from the abdomen without extending abdominal incisions. Despite widespread use of morcellation, complications still remain underreported and poorly understood. We performed a systematic review of surgical centers in the United States to identify, collate and update the morcellator-related injuries and near misses associated with powered tissue removal. We searched articles on morcellator-related injuries published from 1993 through June 2013. In addition, all cases reported to MedSun and the FDA device database (MAUDE) were evaluated for inclusion. We used the search terms “morcellation,” “morcellator,” “parasitic,” and “retained” and model name keywords “Morcellex,” “MOREsolution,” “PlasmaSORD,” “Powerplus,” “Rotocut,” “SAWALHE,” “Steiner,” and “X-Tract.” During the past 15 years, 55 complications were identified. Injuries involved the small and large bowels (n = 31), vascular system (n = 27), kidney (n = 3), ureter (n = 3), bladder (n = 1), and diaphragm (n = 1). Of these injuries, 11 involved more than 1 organ. Complications were identified intraoperatively in most patients (n = 37 [66%]); however, the remainder were not identified until up to 10 days postoperatively. Surgeon inexperience was a contributing factor in most cases in which a cause was ascribed. Six deaths were attributed to morcellator-related complications. Nearly all major complications were identified from the FDA device database and not from the published literature. The laparoscopic morcellator has substantially expanded our ability to complete procedures using minimally invasive techniques. Associated with this opportunity have been increasing reports of major and minor intraoperative complications. These complications are largely unreported, likely because of publication bias associated with catastrophic events. Surgeon experience likely confers some protection against these injuries. Understanding and implementing safe practices associated with the use of the laparoscopic morcellator will reduce these iatrogenic injuries.     

Fístula cutáneo-uterina poscesárea

A fistula is an abnormal communication between two epithelial surfaces. Although fistulas that wrap around the uterus are not infrequent, uterocutaneous fistula is rare. The treatment of choice is abdominal hysterectomy with excision of the fistula up to the skin. We report two cases of uterocutaneous fistula requiring surgical treatment.     

宫腔镜下清宫术治疗剖宫产瘢痕妊娠前不同预处理方式的疗效分析

目的:探讨宫腔镜下清宫术治疗剖宫产瘢痕妊娠(CSP)前不同预处理方式的临床效果。方法:回顾性分析2014年10月至2015年10月本院住院中B超检查提示妊娠囊下缘距子宫切口小于1.0 cm行宫腔镜下清宫术并确诊为CSP的患者170例作为研究对象。其中直接行宫腔镜下清宫术的患者23例(A组);行米非司酮+米索前列醇药物治疗后在宫腔镜下行清宫术的患者29例(B组);行米非司酮+甲氨蝶呤+米索前列醇杀胚治疗后在宫腔镜下行清宫术的患者40例(C组);行子宫动脉灌注+介入栓塞术后在宫腔镜下行清宫术的患者78例(D组),比较4组患者治疗效果。结果:①所有患者手术顺利,无一例发生术中大出血和组织残留,4组患者治疗后血β-HCG较治疗前明显下降,术后血β-HCG、术中出血量、手术时间两两比较,差异无统计学意义(P0.05)。②A组和D组住院时间较短,B组和C组较长,A组与D组住院时间差异无统计学意义(P0.05),但其余两两比较,差异有统计学意义(P0.05)。③A组住院费用最少,D组最多,B组住院费用与C组比较差异无统计学意义(P0.05),但其余两两比较,差异均有统计学意义(P0.05)。④术后不良反应情况:A组术后无一例发生不良反应,B组术后有2例肝功能受损,3例恶心、呕吐等胃肠道反应,C组术后有3例肝功能受损,26例发生胃肠道反应;D组1例发生肝功能受损,16例发热,57例疼痛,对症治疗后好转。结论:CSP的治疗应根据患者病情、经济条件、个人意愿和医院的技术设备条件选择合适的治疗方案。     

The gynecologist and the melanoma: breast and endometrial metastases

Melanoma has an important metastatic potential and its incidence is greatly increasing. Even after many years of negative follow-up, gynecologists should be aware that a gynecological tumor might be a secondary location for a woman with a medical history of melanoma. Because of a poor prognosis and a reduced life expectancy, it is necessary to make a disease staging in order to offer a prompt diagnosis and a personalized strategy of treatment. Considering the increasing incidence of melanoma, gynecologists will face more frequently with this situation.     

Anticoagulación en gestantes portadoras de prótesis mecánicas

Objective

To study distinct anticoagulation regimens in pregnant women with prosthetic heart valves.

Subjects and methods

We performed a systematic review of the literature to determine the required levels of anticoagulation prophylaxis, timing of the introduction of oral anticoagulation and its substitution by heparins, and the maternal and fetal risks associated with different anticoagulation regimens.

Results

A target international normalized ratio (INR) of 2.5-3.5 should be achieved. Although consensus on the heparin of choice is lacking, heparin dose requirements should be based on anti-factor Xa levels (around 1.0 U/mL) or activated partial thromboplastin time (aPTT) (2-3 times control value). The risk of thrombosis in heparin-treated patients is approximately 7%, while the incidence of heparin embryopathy ranges from 1.6-7.4%. The switch from oral anticoagulation to heparin should be made no later than at weeks 35-36 of pregnancy.

Conclusions

The nticoagulation therapy of choice in the first trimester of pregnancy cannot currently be established. Prospective and randomized studies are required to determine the advisability of one treatment over the other     

Gestación multifetal yatrogénica

Multiple pregnancies spontaneously occur in one out of 90 pregnancies for twins and in one out of 8,100 for triplets. However, since the introduction of human reproduction units, there has been a 52% increase in twins, and a 404% increase in high-order pregnancies. Given the high perinatal and maternal morbidity and mortality in these pregnancies, selective embryo reduction was developed to increase fetal survival and reduce long-term morbidity in neonates. Although effective, this procedure represents a technical and ethical challenge for the practitioner. Consequently, we believe that the most effective approach to multifetal pregnancies is primary prevention.     

Retrospective study of 184 superior pedicle breast reductions without drainage

Background

The safety of non-drainage has already been proven on inferior pedicle breast reduction techniques while other authors said that the superior pedicle breast reduction techniques increase the risk of postoperative drainage. We want to prove that non-drainage of superior pedicle breast reduction techniques is as safe as the non-drainage of inferior pedicle breast reduction techniques.

Methods

We made a retrospective study of 184 superior pedicle breast reductions in the last 5 years at the hospital of Lille. The complications were compared with the review of inferior pedicle breast reduction on the previous studies.

Results

We observed: 1.35% of hematomas, 0.54% of fat necrosis, 0.27% of infections, 4.1% of wounds dehisences, 0.81% of nipple loss and no seroma. No significant statistical difference between the complication rate of these two breast reductions techniques was found.

Conclusion

Non-drainage in superior pedicle breast reduction techniques is as safe as the non-drainage in inferior pedicle breast reduction techniques and can be considered as reliable.     

微小RNA在子宫内膜异位症中的研究进展

子宫内膜异位症（endometriosis,EMs）是一种极具复发性和侵袭性的良性疾病,严重影响育龄女性的生活质量。目前临床上缺乏有效的生物标志物,是造成诊断延迟的重要原因之一。随着疾病的进一步进展,EMs给患者带来严重的健康损害和经济负担。目前,腹腔镜检查是确诊EMs的方法,但因其有创、手术并发症及费用昂贵等特点,限制了临床应用。探索敏感度和特异度均佳的生物标志物对于EMs的无创性早期诊断至关重要。微小RNA（microRNA,miRNA）是一类非编码小分子RNA,具有高度的组织特异性和稳定性,近年研究表明miRNA可作为EMs诊断的潜在生物标志物,早期识别有助于对患者的及时诊断和优化治疗。综述miRNA在EMs中的研究进展。     

Implante intratubárico en anticoncepción: ventajas e inconvenientes

This article aims to report our experience of the clinical application of a new procedure for permanent reproductive sterilization (Essure^®) and to discuss its unquestionable advantages and disadvantages. The mean time of the implantation procedure was approximately 10 minutes (range: 5 to 20) from the beginning of the introduction of the hysteroscope to its withdrawal. We were able to perform this procedure routinely in our hysteroscopy consulting room. Of 115 patients, successful placement was achieved in 112 (97.4% success rate). Of these 112 patients, placement was achieved at the second attempt in three. Placement was not achieved in three patients.     

Do screening-preventative interventions in asymptomatic pregnancies reduce the risk of preterm delivery--a critical appraisal of the literature

Recent research has suggested that women who experience preterm delivery (PTD) may be identified earlier in pregnancy and before onset of symptoms. Interventions commenced at this earlier asymptomatic stage may offer an opportunity to prevent PTD or lengthen gestation sufficiently to reduce adverse perinatal outcome. Our objective was to examine the evidence that supports or refutes this approach to preventing PTD. We therefore conducted a systematic search and critical appraisal of the identified literature. We found evidence that introducing screening-preventative strategies for asymptomatic pregnancies may reduce the rate of PTD. Evidence for screening and selective treatment exists for: asymptomatic bacteriuria; bacterial vaginosis in low-risk population groups; elective cervical cerclage in high-risk pregnancies; indicated cervical cerclage in women with short cervical length on ultrasound; prophylactic progesterone supplementation in high-risk pregnancies, and smoking cessation. However, for most other strategies, such as increased antenatal attendance, or routine administration of prophylactic micronutrients, the evidence is inconsistent and conflicting. Information on neonatal outcomes apart from PTD (such as serious neonatal morbidity and mortality) was found to be lacking in most studies. It was therefore not possible to establish whether preventing PTD or prolonging gestation would correlate to improved perinatal outcome, and this lessened the potential clinical usefulness of any proposed preventative strategy. No studies were found that evaluated the effectiveness of combining screening-preventative strategies. The review concludes with a suggested an antenatal management plan designed to prevent PTD based on current practice and the evidence presented in this article.     

Endocavitary surgical procedures, an alternative to myomectomy in patients with symptomatic fibroids

Endometrial ablation can be used in heavy menstrual bleeding due to symptomatic submucosal myomas in women without desire of pregnancy. Those methods used alone, lead to an improvement on bleeding but results are not as good as in women without myomas. They can be associated with hysteroscopic myomectomy and, then, the results on bleeding are better than myomectomy alone. Second generation endometrial ablation methods must be used preferentially as they present less surgical complications than first generation methods. As the pregnancies that may occur after endometrial ablation have high risk of complications, a contraceptive mean is highly recommended after surgery. Transcervical sterilisation by intratubal insert (Essure) can also be proposed, but for women with Essure placed before endometrial ablation, only Thermachoice and bipolar resection have proven their safety. Finally, economical outcomes of endometrial ablation in myomas haven't been assessed yet.
