Use of paracervical analgesia for outpatient hysteroscopic surgery: A randomized, double-blind, placebo-controlled study

Twenty-five women receiving sedation for outpatient hysteroscopic polypectomy were injected with 0.25% bupivacaine 10 mL (paracervical group) and another 25 received the same volume of saline (control group) at the cervical fornix. Both groups were given target-controlled propofol sedation during the procedure. More propofol (mg/min) was needed for adequate anesthesia in the control group compared to the paracervical group (6.5 versus 4.6). In addition, the postoperative pain scores were lower in the paracervical group than in the control group. Hemodynamic changes and postoperative side effects were similar in the two groups. This prospective, randomized, double-blind, placebo-controlled study confirmed the effective use of paracervical blocks. This approach has the effect of reducing the amount of intraoperative propofol and decreasing postoperative pain in outpatient hysteroscopic surgery.     

Transvaginal ultrasound and diagnostic hysteroscopy as a predictor of endometrial polyps: risk factors for premalignancy and malignancy

The aim of this study is to assess accuracy of transvaginal ultrasound (TVUS) and diagnostic hysteroscopy in diagnosing endometrial polyps and to determine premalignancy and malignancy rates in asymptomatic women. The study was designed to retrospectively analyze 438 women who underwent operative hysteroscopy in a day-care unit when endometrial polyp was suspected after TVUS and diagnostic hysteroscopy. Multivariate logistic regression modeling showed effects of age, previous breast cancer with tamoxifen treatment, and menopause with or without bleeding on pathologic results. The results indicate that positive predictive value of TVUS with diagnostic hysteroscopy was 79.9%. Premalignancy or malignancy occurred in 3.2% and was significantly related to menopause with abnormal bleeding (P < 0.001), which carried a 20-fold higher risk of pathology than any other group. Age was also a risk factor. It was concluded that TVUS with diagnostic hysteroscopy reliably evaluates endometrial polyps. The low incidence of endometrial tumors in asymptomatic (especially premenopausal) women suggests that their operative evaluation may not be cost effective. Larger studies are needed to support this tentative conclusion.

为比较宫腔镜辅助下分段诊刮术与单纯分段诊刮术在诊断子宫内膜癌中的临床意义 ,将经手术后病理证实的子宫内膜癌患者分为 2组 :宫腔镜辅助下分段诊刮组 (A组 ) 3 1例 ;单纯分段诊刮组 (B组 ) 3 9例。比较 2组术前诊断子宫内膜癌的准确性及开腹手术时腹水细胞学的检查结果。 2组患者的年龄、临床病理分期、病理分级及组织学类型差异无显著性。A组诊断宫颈受累的准确率为 96.77% (3 0 / 3 1 ) ,假阳性率为 3 .2 3 % (1 / 3 1 ) ;B组分别为 79.49%(3 1 / 3 9) ,1 5 .3 8% (6/ 3 9)。 2组准确率比较 ,差异有显著性 (P <0 .0 5 )。取腹水或腹腔冲洗液行细胞学检查。A组细胞学阳性率为 6.45 % (2 / 3 1 ) ,B组为 1 4.2 9% (3 / 2 1 ) ,2组间差异无显著性 (P >0 .0 5 )。提示 :宫腔镜辅助下分段诊刮术可提高术前诊断子宫内膜癌的准确性 ,从而避免不必要地扩大手术范围 ,而且不增加腹腔内播散的危险。     

An analysis of fluid loss during transcervical resection of submucous myomas

Objective: To determine the contribution of several variables to fluid loss during transcervical resection of submucous myomas.Design: An observational study using multiple linear regression analyses.Setting: A university-affiliated training hospital and a university department of clinical epidemiology and biostatistics.Patient(s): Patients with submucous myomas.Intervention(s): Transcervical resection of submucous myomas and monitoring of fluid loss.Main Outcome Measure(s): Patient age, uterine enlargement, treatment with GnRH analogues or 8-ornithine-vasopressin, type of anesthesia, number of myomas, intramural extension of the myoma (type of myoma), and operating time were tested as variables.Result(s): Only intramural extension of the myoma and operating time were obviously related to fluid loss. For the other variables, such a relation was weak at best. The relation between fluid loss and operating time was not modified by any of the other variables.Conclusion(s): Because fluid loss is an important limiting factor in the transcervical resection of submucous myomas, special attention should be paid to reduction of the operating time and preoperative assessment of the intramural extension of the myoma to guide appropriate patient selection.     

Current treatment options for abnormal uterine bleeding: an evidence-based approach

Heavy menstrual bleeding is the predominant complaint in women with abnormal uterine bleeding. Treatment options are drug therapy, and first- and second-generation endometrial resection. Many women will subsequently have a hysterectomy. Uterine fibroids are the most common solid pelvic tumours in women, and although many fibroids seem to cause no symptoms, they can have serious adverse effects and impact on quality of life. As women postpone having children, gynaecologists will have to manage fibroids and polyps in a conservative manner. The past decade has witnessed the development of highly sophisticated diagnostic and therapeutic technology for women suffering from menorrhagia, fibroids and polyps, including minimally invasive uterine therapy. The tools currently at our disposal permit greater management flexibility, which must be tailored to the individual clinical situation. This chapter reviews the evidence-based approach and minimally invasive therapy.     

宫腔镜手术的麻醉处理

目的探讨宫腔镜手术麻醉方式的选择及其对患者呼吸循环的影响以及对水中毒预防的体会。方法选取416例妇科宫腔镜手术患者,根据手术种类及难易程度分别采用静脉全麻,腰-硬联合阻滞麻醉及静-吸复合全麻。术中连续监测各项生命体征,观察麻醉前后对患者呼吸循环的影响。同时为防止水中毒的发生,凡是手术时间超过1h,膨宫液超过10000ml以上的宫腔镜手术,预防性地应用呋塞米20~40mg。结果静脉麻醉诱导后,全组病人的RR(呼吸频率),HR(心率),MAP(平均动脉压)均有不同程度降低,与诱导前比较有显著性差异(P<0.01)但仍在正常范围内,无需处理,术毕即恢复正常。在正常吸氧情况下SpO2(血氧饱和度)差异无显著性(P>0.05)。联合阻滞麻醉前后各时点的HR,MAP,RR,SpO2均无明显变化。结论虽然宫腔镜手术是微创手术,但潜在的危险性依然存在,对于麻醉来说,除了选择合适的麻醉方式,为手术提供良好的镇静和肌松条件外,还要进行一系列麻醉监测,密切观察患者的各项生命体征,适当地使用呋塞米可有效预防水中毒。     

子宫内膜息肉的宫腔镜诊断和治疗价值

目的：阐明官腔镜对子宫内膜息肉的诊断和治疗价值。方法：对行宫腔镜检查的1676例患者中360例子宫内膜息肉进行研究分析，对其中的56例行经宫颈子宫内膜息肉电切术(TCRP)，术后3个月常规复查。结果：子宫内膜息肉的患病率为21．5％(360／1676)，绝经后子宫出血患者阳性病例为186例，其中子宫内膜息肉43例(23．1％)。结论：(1)子宫内膜息肉的临床特征以不规则阴道出血为主，绝经期则以绝经后出血为主；(2)绝经后妇女体内仍有雌激素持续作用；(3)宫腔镜是子宫内膜息肉诊断和治疗的首选方法。     

Case report: Osseous metaplasia of the endometrium: a rare cause of infertility and its hysteroscopic management

This case report presents a very rare and long-standing causeof infertility, osseous metaplasia of the endometrium, and describesits successful management by hysteroscopy. A woman with a historyof induced abortion 12 years ago, failed to conceive from thattime on. The infertility work-up was unrevealing except forthe presence of intracavitary calcification on ultrasonography.After diagnostic hysteroscopy, solid bony spicules coveringthe posterior wall of the endometrial cavity were removed bywire loop resectoscope. Histology established the diagnosisof osseous metaplasia of the endometrium. The patient conceivedin her second spontaneous cycle and has an ongoing pregnancyat the time of writing. Hysteroscopy was an effective meansof extracting this heterotopic tissue, thereby re-establishingfertility even after a long period of infertility.
