  • Short-Term Effectiveness and Safety of Laparoscopic versus Open Left Hepatectomy for Primary Cancer: A Systematic Review

    Objective To evaluate the short-term effectiveness and safety of laparoscopic versus conventional open left hepatectomy. Methods Databases including CENTRAL (Issue 1, 2012), MEDLINE/PubMed (1978 to 2012), EMbase (1966 to 2012), CBM (1978 to 2012), CNKI (1979 to 2012) and the Chinese Medical Association Figures Journal Systems (1990 to 2012) were searched to collect clinical trials on laparoscopic versus conventional open left hepatectomy. Relevant proceedings and references of the included studies were also retrieved manually. According to the inclusion criteria, two reviewers independently screened literature, extracted data and assessed quality. Then meta-analysis was conducted using RevMan5.0 software. Results No randomized controlled trials were collected, and a total of 5 clinical concurrent controlled trials involving 319 patients were included finally. The results of meta-analysis showed that, compared with the conventional open group, the laparoscopic group was longer in the operation time (WMD=40.89, 95%CI 29.39 to 55.38, Plt;0.000 01), and was lower in the intraoperative blood loss (WMD=−107.84, 95%CI −208.96 to −6.73, Plt;0.04); but there was no significant difference between the two groups in terms of hospital stays (WMD=−3.78, 95%CI −9.60 to 2.04, P=0.20) or postoperative complications (WMD=0.69, 95%CI 0.37 to 1.29, P=0.25). Conclusion As a minimally invasive technique, laparoscopic left hepatectomy has advantages of small abdominal incision and less intraoperative blood loss, and it is helpful to improve the quality of life for patients. Due to the limitation of quantity and quality of the included studies, it is hard to estimate the impact of bias on the reliability of this conclusion. We advise to perform more high quality, large scale and multicenter studies with adequate follow-up in the future.

  • Effectiveness and Safety of Different Laparoscopic Surgeries for Ovarian Endometrioma: A Systematic Review

    Objective To systematically review the effectiveness and safety of different laparoscopic surgeries for ovarian endometrioma (OE). Methods Such databases as The Cochrane Library (Issue 3, 2011), MEDLINE (1966 to November 2011), EMbase (1980 to November 2011), CNKI (1980 to November 2011), CBM (1980 to November 2011) and WanFang Data (1978 to November 2011) were searched on computer, and the relevant references of the included literature were also retrieved manually to collect the randomized controlled trials (RCTs) about laparoscopic cystectomy vs. laparoscopic coagulation for OE. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data and assessed quality. Then RevMan 5.1 software was used for meta-analysis. Results A total of 5 RCTs were included. The results of meta-analysis showed that, laparoscopic cystectomy for OE could reduce the reocurrence rates of dysmenorrhoea (RR=0.29, 95%CI 0.15 to 0.55, P=0.000 2), dyspareunia (RR=0.27, 95% CI 0.09 to 0.77, P=0.01) and non-menstrual pelvic pain (RR=0.19, 95% CI 0.05 to 0.76, P=0.02), decrease 1-year (RR=0.33, 95%CI 0.15 to 0.74, P=0.007) and 2-year (RR=0.49, 95%CI 0.26 to 0.95, P=0.03) postoperative reoccurence of OE, and lower the risk of short-term secondary operation (RR=0.25, 95%CI 0.07 to 0.85, P=0.03). However, it didn’t increase the 12-month (RR=2.82, 95%CI 1.44 to 5.50, P=0.002) and 24-month (RR=2.62, 95%CI 1.47 to 4.68, P=0.001) postoperative spontaneous pregnancy rates (SPR). In addition, although laparoscopic coagulation was superior to laparoscopic cystectomy in the 6-month postoperative ovarian reserve function (ORF), there was no significant difference in the 5-year postoperative ORF between the two groups (WMD=0.27, 95%CI −0.18 to 0.73, P=0.24). Conclusion Laparoscopic cystectomy for OE can reduce the reoccurence of dysmenorrhoea, dyspareunia, non-menstrual pelvic pain and endometriosis, decrease the risk of short-term secondary operation, and increase the postoperative SPR in women who had been diagnosed as infertility. Because of the quantity limitation of present clinical trials, this conclusion requires to be further proved by performing more high quality RCTs.

  • Effectiveness and Cost of Laparoscopic versus Traditional Abdominal Myomectomy in China: A Systematic Review

    Objective To systematically evaluate the effectiveness and cost of laparoscopic myomectomy (LM) vs. traditional abdominal myomectomy (TAM) in treating Chinese patients with hysteromyoma. Methods Such databases as The Cochrane Library (Issue 4, 2012), PubMed, EMbase, CNKI, CBM and WanFang Data were searched from their inception to September, 2012 to collect the randomized controlled trials (RCTs) about LM vs. TAM in treating Chinese patients with hysteromyoma, and the references of the included studies were also retrieved. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data and assessed the methodological quality. Then meta-analysis was conducted using RevMan 5.2 software. Results A total of 8 RCTs involving 1 000 Chinese patients were included. The results of meta-analysis showed that, LM was superior to TAM in postoperative exhaust time (WMD= ?15.21, 95%CI ?20.19 to ?10.24, Plt;0.000 01) and postoperative hospital stay (WMD= ?3.07, 95%CI ?4.25 to ?1.90, Plt;0.000 01), with significant differences. But it was inferior to TAM in operation time (WMD=28.33, 95%CI 18.07 to 38.59, Plt;0.000 01) and hospital costs (WMD=2 028.87, 95%CI 1 190.75 to 2 866.98, Plt;0.000 01), with a significant difference. There was no significant difference in intraoperative bleeding amount between the two groups (WMD= ?2.78, 95%CI ?41.56 to 36.00, P=0.89). Conclusion This study shows LM is superior to TAM in fastening postoperative recovery and shortening hospital stay, but it is longer in operation time and higher in cost. The intraoperative bleeding amount is similar in the two groups. Due to low methodological quality and small sample size of the included studies, this conclusion has to be further proved by more high-quality RCTs.

  • Clinical Effectiveness and Safety of Laparoscopy versus Laparotomy for Endometrial Cancer: A Meta-Analysis

    Objective To assess the clinical effectiveness and safety of laparoscopy versus laparotomy for endometrial cancer. Methods The databases such as The Cochrane Library, PubMed, EMbase, Ovid, CNKI, WanFang Data, and VIP were searched to collect the randomized control trials (RCTs) about the clinical effectiveness and safety of laparoscopy and laparotomy for endometrial cancer. The retrieval time was from January 1998 to September 2012. Two reviewers independently screened the literature according to the inclusive and exclusive criteria, extracted the data, and assessed the methodological quality of included studies. Then the meta-analysis was performed by using RevMan 5.0 software. Results A total of 10 RCTs involving 6 993 patients were included. Meta-analysis showed that, compared with laparotomy, laparoscopy had lesser amount of intraoperative bleeding, lower decrease of hemoglobin before and 1-day after operation, shorter time of both waiting for postoperative gas and hospital stay, lower incidence of postoperative complications, longer operation time, and higher incidence of intraoperative complications. Additionally, there were no differences between the 2 groups in the number of pelvic and para-aortic lymph nodes removed during operation, as well as the postoperative recurrence and mortality rates in 3-5 year follow-up. Conclusion Compared with laparotomy, laparoscopy shows lesser amount of intraoperative bleeding, lower decrease of hemoglobin before and 1-day after operation, shorter time of both waiting for postoperative gas and hospital stay, lower incidence of postoperative complications. But laparotomy shows lower incidences of intraoperative complications, and shorter operation time. Both operations are similar in the number of pelvic and para-aortic lymph nodes removed during operation, as well as the postoperative recurrence and mortality rates in 3-5 year follow-up. For quantity limitation and low methodological quality of included studies, this conclusion still needs to be further proved by performing more high-quality and large scale RCTs.

  • Laparoscopic Surgery versus Laparotomy for Women with Polycystic Ovarian Syndrome: A Systematic Review

    Objective To compare the efficacy and incidence of complications between laparoscopic surgery and laparotomy on women with polycystic ovarian syndrome (PCOS). Methods We did a systematic literature search for studies from Ovid Database, MEDLINE, EMbase, Cochrane Library (Issue 2, 2008), Chinese Biological Medicine Database, CNKI, Chinese VIP Database, and WANFANG Database on internet. The search time was from establishment of each database to December, 2008. Randomized controlled trials and non-randomized controlled trials were collected. The search was no limitation in language. We manually searched current and conference abstracts, and searched relevant reviews and their reference. RevMan 5.0 software was used for meta-analysis. Results Five non-randomized trials involving 417 patients were included. The results of meta-analyse showed that the short-term pregnancy rate in patients underwent laparoscopic surgery was significantly higher than that in patients underwent laparotomy (RR=1.42, 95% CI 1.13 to 1.80, P=0.003). The long-term pregnancy rate in patients underwent laparoscopic surgery and laparotomy was comparable (RR=0.85, 95%CI 0.68 to 1.07, P=0.17). The regular menstruation in patients underwent laparoscopic surgery and laparotomy was comparable (RR=0.91, 95%CI 0.79 to 1.05, P=0.18). The uterine adhesions in patients underwent laparoscopic surgery was significantly lower than that in patients underwent laparotomy (RR=0.02, 95%CI 0.00 to 0.18, P=0.000 2). The intra-abdominal adhesions of patients underwent laparoscopic surgery was significantly lower than that in patients underwent laparotomy (RR=0.02, 95%CI 0.00 to 0.13, Plt;0.000 1).Conclusions The limited evidence at present shows that the incidence and degree of pelvic adhesions occurred in patients with PCOS after laparoscopic surgery is much lower than those after laparotomy. It is not quite sure at this point about whether the pregnancy rate and regular menstruation of laparoscopic surgery are better than those of lararotomy or not. More evidence from high qualified multi-center studies is needed.

  • Liver Function Alterations and Its Influencing Factors after Laparoscopic-Assisted Radical Gastrectomy for Gastric Cancer

    Objective To evaluate the changes of liver function after laparoscopic-assisted radical gastrectomy for gastric cancer and analyze related impact factors. Methods Patients with gastric cancer or colon cancer, who underwent radical gastrectomy or hemicolectomy between Jun 2008 and Jun 2010 in General Hospital of PLA, were included in this study. These patients were divided into open gastrectomy (OG group, n=43), laparoscopic-assisted gastrectomy (LAG group, n=35), and laparoscopic-assisted hemicolectomy (LAC group, n=23). The serum AST, ALT, TB, and ALP levels of all patients enrolled on the preoperative day and post operative day (POD) 1, POD3, POD5, and POD7, and related impact factors were analyzed. Results Compared with the preoperative results, serum AST and ALT levels of patients increased until POD5 in both LAG and OG groups (P<0.05), and there was no changes in liver function after operation of patients in LAC group (P>0.05). In addition to that serum AST and ALT levels of patients in LAG group in POD1 were significantly higher than those in OG group (P=0.035 and P=0.041), and that serum ALT level of patients in LAG group was significantly lower than that in OG group in POD3 (P=0.048), serum AST and ALT levels of patients in two groups in the remaining time points were not statistically significant difference (P>0.05). The serum AST and ALT levels of patients in LAG group were significantly higher than those in LAC group during 5 d after operation (P<0.05).There was no significant changes of serum ALP and TB levels of patients in LAG and OG groups on the before and after operation (P>0.05). The increased serum ALT level of gastric cancer patients after operation related to body mass index (BMI, P=0.038), operative time (P=0.011), intraoperative hepatic injury (P=0.035), and abnormal ligation of hepatic artery (P=0.048), instead of the type of operation (OG vs.LAG, P>0.05). Conclusions Gastric cancer patients who underwent radical gastrectomy have transient liver dysfunction, which attributes mainly to direct liver manipulation or abnormal ligation of hepatic artery, but not CO2 pneumoperitoneum. Laparoscopic-assisted radical gastrectomy is feasible and safe to the patients without serious liver damage or other vital organs disorders.
