The objective of this study was to introduce the nerve plane-sparing radical hysterectomy technique and compare its efficacy and safety with that of nerve-sparing radical hysterectomy. Methods From September 2006 to August 2010, 73 consecutive patients with International Federation of Gynecology and Obstetrics stage IB to IIA cervical cancer underwent radical hysterectomy with two different nerve-sparing approaches. Nerve-sparing radical hysterectomy was performed for the first 16 patients (nerve-sparing radical hysterectomy group). The detailed autenomic nerve structures were identified and separated by meticulous dissection during this procedure. After January 2008, the nerve plane-sparing radical hysterectomy procedure was developed and performed for the next 57 patients (nerve plane-sparing radical hysterectomy group). During this modified procedure, the nerve plane (meso-ureter and its extens;ion) containing most of the autonomic nerve structures was integrally preserved. The patients' clinicopathologic characteristics, surgical parameters, and outcomes of postoperative bladder function were compared between the two groups. Results There were no significant differences between the nerve plane-sparing radical hysterectomy and nerve-sparing radical hysterectomy groups regarding age, International Federation of Gynecology and Obstetrics stage, pathological type, preoperative treatment, or need for intraoperative blood transfusion. The nerve plane-sparing radical hysterectomy group had a higher body mass index than that of the nerve-sparing radical hysterectomy group (P=0.028). The mean surgical duration in the nerve plane-sparing radical hysterectomy and nerve-sparing radical hysterectomy groups were (262_+46) minutes and (341+36) minutes (P 〈0.01). On the 8th postoperative day, 41 (71.9%) patients in the nerve plane-sparing radical hysterectomy group and nine (56.3%) patients in the nerve-sparing radical hysterectomy group had a postvoid residual urine volume of 〈100 ml (P=0.233). The median duration of catheterization was eight days (range 8-23 days) for the nerve plane-sparing radical hysterectomy group and eight days (range 8-22 days) for the nerve-sparing radical hysterectomy group (P=-0.509). Neither surgery-related injury nor pathologically positive margins were reported in either group. Conclusion Nerve plane-sparing radical hysterectomy is a reproducible and simplified modification of nerve-sparing radical hysterectomy, and may be preferable to nerve-sparing radical hysterectomy for treatment of early-stage invasive cervical cancer.展开更多

文摘目的比较传统的根治性子宫切除术和保留盆腔自主神经的根治性子宫切除术治疗宫颈癌的疗效。方法检索Pub Med、EMBASE、CBMdisc、CNKI和Wanfang数据库,收集符合纳入标准的随机对照试验。运用Stata software(version 11.0)对数据进行统计分析。结果纳入19项临床同期对照试验共计1 862例患者。分析显示,1术后膀胱功能比较:术后残余尿<50 m L及<100 m L的恢复时间分别为加权均数差=-6.62、95%可信区间(-7.00,-6.23)及加权均数差=-5.04、95%可信区间(-6.52,-3.56),膀胱功能紊乱的发生率比较的相对危险度=0.46,95%可信区间(0.29,0.71);2术后肠道功能比较:术后排气及排便时间分别为加权均数差=-12.02,95%可信区间(-16.20,-7.85)及加权均数差=-20.99,95%可信区间(-32.02,-9.96);3术后生存率及2年、4年、5年复发率差异无统计学意义,术后2年复发率比较相对危险度=1.21,95%可信区间(0.73,2.01),P=0.452;4单个研究提示与经腹根治性子宫切除术组相比,保留盆腔自主神经的根治性子宫切除术组患者的直肠功能紊乱、性功能紊乱发生率较低,且保留盆腔自主神经的根治性子宫切除术组术后生活质量较高。结论与传统根治性子宫切除术相比,保留盆腔自主神经的根治性子宫切除术具有术后膀胱、直肠及性功能恢复快的优点;保留盆腔自主神经的根治性子宫切除术提高了患者的生活质量,并不影响患者术后宫颈癌的复发率和生存率。本系统评价的结论需要随访时间更长的大样本随机对照研究加以验证。
