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.
目的 探讨腹腔镜下乙状结肠癌根治术保留盆腔自主神经的可行性及对术后泌尿、生殖功能的影响。 方法 选取2007年8月－2009年7月60例行腹腔镜下乙状结肠癌根治术患者，手术按标准腹腔镜下乙状结肠癌前切除手术方式操作。术后采用问卷调查方式对患者术后泌尿功能、男性勃起功能、女性性功能进行效果评价。生殖泌尿功能评估包含国际前列腺增生评分（IPSS）、国际勃起功能评分量表（IIEF）、女性性功能评估量表（FSFI）。 结果 58例患者成功保留自主神经，56例接受术后泌尿、生殖功能测定，置放尿管时间为1～7 d，平均3 d，拔除尿管后排尿功能良好（IPSS 0～7分）57例（95.0%），一般（IPSS 8～14分）2例（3.3%），差（IPSS 15～35分）1例（1.7%），术前、术后IPSS评分差异无统计学意义（P=0.075）。30例男性患者术后，射精良好27例（90.0%），一般2例（6.7%），差1例（3.3%）；但是勃起功能测定良好（IIEF 60～75分）28例（93.4%），一般（IIEF 44～59分）1例（3.3%），差（IIEF 5～43分）1例（3.3%），术前、术后IIEF差异无统计学意义。26例女性患者术后性功能评分，良好（FSFI 76～95分） 23例（88.5%），一般（FSFI 58～75分） 2例（7.7%），差（FSFI 4～57分）1例（3.8%）。盆腔神经保留成功的患者术前、术后差异无统计学意义（P=0.122）。 结论 多数腹腔镜下乙状结肠癌根治术患者能有效保留盆腔自主神经，且术后能保留泌尿、生殖功能。
ObjectiveTo investigate the effect of pelvic autonomic nerve preservation (PANP) with total mesorectal excision (TME) on sexual and urinary function in male rectal cancer patients. MethodsClinical data of eightyfour patients with rectal cancer from January 2008 to October 2010 in our hospital were analyzed. According to different operative techniques, all the patients were divided into two groups: PANP+TME group (n=41) and TME group (n=43). The sexual dysfunction, urination disorder rate, and local recurrence rate after operation of patients between two groups were compared. ResultsErectile dysfunction rate of patients in TME+PANP group and TME group was 29.3% (12/41) and 76.7% (33/43), ejaculation disorder rate was 26.8% (11/41) and 79.1% (34/43), and urination dysfunction rate was 24.4% (10/41) and 79.1% (34/43), respectively. The rate of sexual and urinary dysfunction of patients in TME+PANP group was significantly lower than that in TME group (Plt;0.05). Local recurrence rate of patients in TME+PANP group (9.8%, 4/41) was similar to that in TME group (11.6%, 5/43)， Pgt;0.05. ConclusionPANP based on TME can reduce effectively the rate of sexual and urinary dysfunction in male rectal cancer patients, which does not increase the local recurrence rate after operation.
