Objective To assess the safety and effectiveness of laparoscopic hysterectomy (LH) for women with benign gynecological diseases. Methods Such databases as CENTRAL (The Cochrane Library, Issue 5, 2012), MEDLINE, EMbase, CNKI, WanFang Data, VIP and CBM were searched from the date of their establishment to May 2012, meanwhile the relevant gray literature was also retrieved to identify the randomized controlled trials (RCTs) about LH versus abdominal hysterectomy (AH) for benign gynecological diseases. The literature was screened according to the inclusion and exclusion criteria by two reviewers independently, and the methodology quality was evaluated after extracting the data, then RevMan 5.1 software was used for meta-analysis. Results A total of 22 RCTs involving 3 304 patients were included. The results of meta-analysis showed that, compared with AH, LH was shorter in the time of both hospital stay (MD=–2.31, 95%CI –3.03 to –1.60, Plt;0.000 01) and postoperative recovery (MD=−13.86, 95%CI −17.70 to −10.03, Plt;0.000 01), and lower in the incidences of both postoperative fever and other nonspecific infections (OR=0.72, 95%CI 0.54 to 0.95, P=0.02), but it was higher in the incidence rate of intraoperative urinary systematic injuries (OR=2.41, 95%CI 1.21 to 4.82, P=0.012), and longer in the operation time (MD=20.27, 95%CI 3.95 to 36.59, P=0.03). There were no significant differences between the two groups in the incidence of complications such as intraoperative intestinal injuries, vessel injuries, postoperative fistulizaion, postoperative urethral dysfunction, postoperative vaginal infection, etc. (Pgt;0.05). Conclusion This systematic review shows when treating benign gynecological diseases, LH is superior to AH in shortening the time of hospital stay and postoperative recovery, and in decreasing the incidence of operative fever and other nonspecific infections, but it results in a higher incidence of intraoperative urinary systematic injuries and longer operative time. Because there is no result regarding to the postoperative long-term life quality, so it expects to be further proved by more high quality RCTs.
Objective To assess the efficacy and safety of laparoscopic nerve-sparing radical hysterectomy (LNSRH) in treatment of early cervical cancer. Methods Such databases as CBM (1960 to September 2011), CENTRAL (1966 to September 2011), MEDLINE (1966 to September 2011), The Cochrane Library, EMbase (1974 to September 2011) and CNKI (1994 to September 2011) were searched on computer, and relevant magazines were also searched manually. Data were extracted and the quality was assessed after including studies according to exclusive criteria, then meta-analysis was conducted using RevMan 5.1 software. Results Total 7 studies involving 506 cases were selected, of which 255 cases were in the LNSRH group and the other 251 cases were in the laparoscopic radical hysterectomy (LRH) group. There were no differences between the two groups in age, body mass index, clinical stage, pathological type and histological grade. The results of meta-analysis showed that: a) The operative time of LNSRH was longer than LRH, with significant difference (P=0.02). But there was no significant difference in intraoperative bleeding between the two groups (P=0.69); b) The length of dissected parametrium of LNSRH was shorter than LRH with significant difference (P=0.02). But there was no significant difference in the length of dissected vagina (P=0.69); and c) The functional recovery of the bladder in the LNSRH group was better than LRH (Plt;0.000 01). Conclusion LNSRH is safe and feasible in effectively alleviating the postoperative dysfunction of the bladder in early cervical cancer as well as in improving the quality of life for patients. It is regarded as a new model of operation. Because it has just been put into practice within a short time, and there is lack of multi-center, large-sample, prospective controlled studies at present, so its radical effectiveness, long-term recurrence rate, survival rate, etc. have not yet been confirmed. More high quality studies are needed to provide important data of comparison between LNSRH and LRH.
Objective To evaluate the clinical effect and safety of nerve sparing radical hysterectomy(NSRH) for cervical cancer compared with radical hysterectomy (RH). Methods We searched the Cochrane Library (Issue 2, 2010), MEDLINE (1960 to March, 2010), EMbase (1960 to March, 2010), CBM (1960 to March, 2010), VIP (1960 to March, 2010) and CNKI (1960 to March, 2010), and hand searched related literatures. With a defined search strategy, both randomized controlled trials and controlled clinical trials of comparing NSRH with RH for cervical cancer were identified. Data were extracted and evaluated by two reviewers independently. The quality of the included trials was evaluated by Cochrane’s evaluation criterion. Meta-analysis was conducted with the Cochrane collaboration’s RevMan 4.2.2 software. Results Nine controlled clinical trials involving 742 patients were identified. The meta-analysis showed that: a) There was statistical significance in postoperative recovery of bladder function between two groups; compared with RH, NSRH was much better in aspects of the recovery time of post void residual urine volume (PVR) (WMD= – 5.80, 95%CI – 6.22 to – 5.37), the bladder dysfunction morbidity (RR=0.43, 95%CI (0.26 to 0.75), and the urodynamic study; b) The operation time of NSRH was longer than that of RH with a significant difference (WMD=37.23, 95%CI 12.84 to 61.61); c) There was no significant difference between two groups in bleeding amount (WMD=19.66, 95%CI – 51.57 to 90.90); d) There was no significant difference between two groups in both survival rate and recurrent rate (RR=0.79, 95%CI 0.17 to 3.58); e) There was no significant difference between two groups in resection extension and pathologic outcome, such as, infiltration around uterus and vessels; f) One trail showed a significant difference between two groups that NSRH seldom led to anorectal and sexual dysfunction. Conclusions Compared with RH, NSRH can quickly improve the postoperative recovery of bladder, anorectal and sexual functions, but haven’t larger quantity of operative bleeding, larger resection extension, lower survival rates and higher recurrence rates except longer operation time. NSRH can improve the quality of postoperative life and is safe. However, the trails available for this systematic review were limited, as well as non-randomized controlled trails. Some outcomes were only included by one trail. So there is no confirmed conclusion about these. The prospective randomized controlled trials are required for further investigation.
Objective To compare and assess the effectiveness between total vaginal hysterectomy (TVH), Laproscopical hysterectomy (LH) and minilaporotomy hysterectomy (MiniLPT). Methods We searched CBM, CKNJ, MEDLINE, EMbase, Cochrane DSR, ACP Journal Club, DARE, CCTR, CMR, HTA, and NHSEED to screen randomized controlled trials (RCTs) comparing one surgical approach to another of extrafascial hysterectomy (between TVH, LH and miniLPT) which were done to those women with benign gynecological diseases. As to economy assessment, studies of cost-effective analysis were also included. Those observational studies reporting rare or important long-term outcome were also included. The quality of the included studies was evaluated by GRADE (Grades of Recommendation, Assessment, Development and Evaluation) system and principle of Cochrane Reviewer Handbook 4.2.3 RCT. Results Finally, we identified 12 trials including 10 RCTs, 1 retrospective cohort study and 1 respective cohort study. Cost-effective analy- sis showed when in indication of VH, TVH was more cost-effective than LH. When TVH was less but still accessible, metaanalysis showed TVH had significant advantages than the other two approaches in many sides. Compared with LH arm, operation time was shorter at a WMD 47.2 min and 95%CI 32.2 to 62.3 min, blood loss was less at a WMD 158.7 ml and 95%CI – 190.9 to – 126.4 ml, hospital stay was shorter at a WMD 23.9 h and 95%CI – 25.4 to – 13.9 h, and the first stool or to break wind was quicker at a WMD – 8.1 h and 95%CI – 10.8 to – 5.3 h in TVH arm. But on the other side, the incidence rates of bad wound healing (such as vaginal cuff infection, abdominal wall infection, wound dehiscence, etc.), of secondary infection (such as UTI, URI, unknown infection, etc.), and of febrility were less common in LH arm than those in TVH arm with no significant difference. Meanwhile, ratio of sexual hypofunction, declined marital life quality and worse body image were more in TVH arm than those in LH arm, implying LH arm provided a better post-operation sexual life recovery. Operation time was longest in miniLPT arm at a WMD 37.0 h and 95%CI 13.5 to 60.5 h and blood loss was most at a WMD 208.5 ml and 95%CI 141.4 to 375.7 ml, too. The febrility rate was also the most common in miniLPT arm at a Peto OR 3.8 and 95% CI 1.1 to 12.6. The differences were significant. Conclusion TVH is the least invasive approach and better in cost-effectiveness when accessible. However, when inaccessible, the limitations remain unclear, depending on surgeons’ own techniques and experience as well as patients’ individual conditions. LH does better in improving quality of life and body image. Cost-effectiveness of LH may become much better by reducing blood loss during operation through improving techniques or instruments of hemostasis. Limited application of non-reproducible instrument or cost and promotion of their recycle may help a lot in bringing down LH operation cost, too. Owing to limited studies, the advantage of miniLPT should be evaluated more precisely by its technical development and more penetrating researches. There are huge gaps in standardized high-quality RCTs, performance and research of long-term outcomes and health economy comparing different approaches to total hysterectomy in China.
Objective To examine the length of hospital stay and expenses associated with hysterectomy in China and to compare the results with those from developed counties, so as to provide comparative information about hysterectomy in China. Methods Hospital discharge data on hysterectomies performed in Peking Union Medical College Hospital from 2002 to 2006 were retrieved. The cases were classified into 3 groups, namely abdominal, laparoscopic and vaginal hysterectomy. The length of hospital stay and expenses associated with hysterectomy were analyzed retrospectively. Results Records of 5975 women who underwent hysterectomies were analyzed, including 3295 cases (65.7%) of abdominal hysterectomy, 1543 (25.8%) cases of laparoscopic hysterectomy (25.8%) and 507 (8.5%) cases of vaginal hysterectomy. The median (mean) postoperative length of stay were 6 (6.4) days, 4 (4.8) days and 5 (5.6) days in the abdominal, laparoscopic and vaginal hysterectomy groups, respectively. These were approximately 2 days longer than those in developed countries. The median total expenses were 6109.0, 7296.3 and 5265.2 RMB in the abdominal, laparoscopic and vaginal hysterectomy groups, respectively. After adjustment for the differences in Gross National Income (GNI) per capita between China and developed countries, the expenses associated with hysterectomy in China were 8.7 and 1.8-4.9 times higher than those in UK and USA, respectively. Conclusion Compared with abdominal and vaginal hysterectomies, laparoscopic hysterectomy is associated with a shorter postoperative length of stay, but with higher hospital cost. Compared with developed countries, hysterectomy is actually more expensive and associated with a longer hospital stay in China.

Methods Form November 2008 to May 2009, fourty patients who had undergone hysterectomy were divided into preemptive analgesia (PA) group and control group, 20 patients in each. The PA and control group were intravenously injected with tramadol (3 mg/kg) and normal saline respectively. Twelve and 24 hours after hysterectomy, the Bolus times, consumption of fentanil, pain score and incidence of PONV were observed. Results Twelve and 24 hours after hysterectomy, the Bolus times and consumption of fentanil were both lower than those in control group(Plt;0.05), the difference of PONV incidences between two groups was not statistically significant (Pgt;0.05). Conclusion Intravenously injected with tramadol before hysterectomy can recduce the dosage of analgesic, and don′t increase the incidence of PONV.
目的:观察静脉应用小剂量氯胺酮超前镇痛法对接受腹腔镜下子宫切除手术患者术后疼痛及认知功能的影响。方法:38例择期接受腹腔镜下子宫切除术患者(ASA分级12)随机分为氯胺酮组和对照组。氯胺酮组于手术开始前5min静脉滴注氯胺酮015mg·kg-1,术中持续泵注3μg·kg-1·min-1至手术结束;对照组使用生理盐水。记录术中使用氯胺酮后心率,平均动脉压的变化;术后24h内静脉使用芬太尼的剂量,VAS疼痛评分,头晕、恶心、呕吐等不良反应,中枢神经系统症状以及术后2h患者认知功能。结果:两组患者在24h内静脉使用芬太尼的剂量,VAS疼痛评分,不良反应,中枢神经系统症状以及术后2h的认知功能方面没有统计学差异。〖HTH〗结论:〖HTSS〗静脉使用小剂量氯胺酮超前镇痛并不能减少术后芬太尼的用量,不能降低术后疼痛评分。尽管使用小剂量氯胺酮并没有增加患者术后的不良反应,也不影响患者术后认知功能障碍,不建议作为腹腔镜下子宫切除术患者常规使用。
