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.
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.
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.
ObjectiveTo evaluate the impact of video-assisted thoracoscopic surgery (VATS) esophagectomy and routine operation on the short-term quality of life in patients with esophageal cancer. MethodsFrom January 2012 through January 2014, 157 esophageal cancer patients were classified into a VATS group (n=42) and a routine operation group (n=115) in our hospital. All patients in the two groups completed the Chinese versions of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ)-C30 and QLQ-OES18 at one, six and 12 months after operation separately. ResultsAt the end of 6, 12 months after operation, the evaluation on global health status was higher in the VATS group(68.8±12.3 vs. 62.7±13.7, P<0.05; 76.2±10.4 vs. 68.6±8.8, P<0.05). At the end of 1, 6, 12 months after operation, the scores of symptom pain were less significantly in the VATS group than those in the routine operation group (P<0.05). One month after operation, the score of active ability in the VATS group was higher (P<0.05). At the end of 6, 12 months after operation, the score of emotional function and social role in the VATS group was higher (P<0.05). At the end of 12 months after operation, the score of role function and cognitive function in the VATS group was also higher (P<0.05). ConclusionVATS is of better effect on improving short-term quality of life of esophageal cancer patients compared with routine operation.
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.
Objective To systematically evaluate the effectiveness and safety of laparoscopic hepatectomy (LH) versus open hepatectomy (OH) for hepatocellular carcinoma (HCC). Methods Databases including PubMed, EMbase, MEDLINE, SCI, CNKI, CBM, WanFang Data and The Cochrane Library (Issue 3, 2012) were searched to collect the randomized controlled trails (RCTs) and non-RCTs about LH versus OH for HCC. The retrieval time was from inception to August 2012. The studies were screened according to the inclusion and exclusion criteria, the data were extracted and the quality was evaluated by 2 reviewers independently. Then the meta-analysis was conducted using RevMan 5.1 software. Results A total of 13 non-RCTs involving 701 patients were included. The results of meta-analysis showed that: Compared with OH, LH had lesser amount of intraoperative bleeding (MD=?144.09, 95%CI ?194.25 to ?93.94, Plt;0.000 01), shorter hospital stay (MD=?5.48, 95%CI ?7.10 to ?3.85, Plt;0.000 01), and lower postoperative complications (OR=0.43, 95%CI 0.27 to 0.66, P=0.000 1). But there were no differences between the 2 groups in operation time (MD=?0.64, 95%CI ?22.95 to 21.68, P=0.96), perioperative death rate, 3-5 year survival rate, and tumor free survival rate. Conclusion LH is superior to OH in treating HCC for it is associated with smaller wound, lesser operative blood loss, shorter hospital stay, and lower postoperative complications. And it is similar as OH in operation time, perioperative death rate and 3-5 year survival rate. So LH is safe and feasible for treating HCC when its indications are strictly controlled. However, for the quantity and quality limitation of the included studies, this conclusion still requires to be further proved by performing large scale and high quality RCTs. It suggests that doctors should choose a best therapy for HCC patients according to an integrative disease assessment.
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.
Objective To systematically review the effectiveness and safety of single-incision laparoscopic cholecystectomy (SILC) versus conventional multiport laparoscopic cholecystectomy (CMLC). Methods We electronically searched PubMed, EMbase, The Cochrane Library (Issue 1, 2013), CBM, CNKI, VIP and WanFang Data for randomized controlled trials (RCTs) on SILC versus CMLC from inception to January 1st, 2013. According to the Cochrane methods, the reviewers screened literature, extracted data, and assessed the methodological quality. Then, meta-analysis was performed using RevMan 5.2 software. Results Finally, 17 RCTs involving 1 233 patients were included. The results of meta-analysis showed that, compared with CMLC, SILC was lower in 24 h postoperative pain score (visual analogue scale, VAS) (SMD= –0.40, 95%CI –0.76 to –0.04, P=0.03), higher in cosmetic results score (SMD=1.56, 95%CI 0.70 to 2.43, P=0.000 4), and longer in operative time (MD=13.11, 95%CI 7.06 to 19.16, Plt;0.000 1). However, no significant difference was found in 6 h postoperative pain scores (VAS), postoperative complications, port-site hernia and hospital stay between the two groups. Conclusion SILC is a safe and effective technique for the treatment of uncomplicated benign gallbladder diseases, and it has certain advantages compared with CMLC, which is recommended in clinical application.
Objective To evaluate the efficiency and safety of laparoscopic hepatectomy (LH) and conventional open hepatectomy (OH) in patients with hepatocellular carcinoma (HCC). Methods We searched The Cochrane Library, MEDLINE (1966~2008.3), EMBASE (1966~2008.3), CBM (1979~2008.3), we also handsearched some Chinese journals. Using a defined search strategy, randomized controlled trails and controlled clinical trials of comparing OH with LH for hepatocellular carcinoma were identified. Data were extracted and evaluated by two reviewers independently. The quality of the included trails was evaluated by Deeks JJ’s evaluation criterion. Meta–analysis was done using the Cochrane collaboration’s Revman 4.2.10. Results Seven controlled clinical trials (309 patients) were included, The meta–analysis showed that: (1) Four studies (n=198) reported mortality, the mortality rate of the LH group was not significantly different from that of the OH group [OR=1.14, 95%Cl (0.15, 8.65), P=0.90]; (2) Two studies (n=91) reported blood transfusion. There were no significant differences between the two treatment groups in terms of the blood transfusion [OR=0.20, 95%Cl (0.03, 1.19), P=0.08]; (3) Four studies (n=165) reported operation time. There were significant differences in operating time between the two groups [SMD=1.05, 95%CI (0.72, 1.38), Plt;0.000 01]; (4) Four studies (n=165) reported intraoperative blood loss. There were significant differences in intraoperative blood loss between the two groups [SMD= – 1.56, 95%Cl (– 2.39, – 0.73), P=0.000 2]; (5) Five studies (n=210) reported the duration of hospital stay. There were significant differences in duration of hospital stay between the two groups [WMD= – 3.89, 95%CI (– 5.54, – 2.23), Plt;0.000 01]; (6) Two studies (n=248) reported complications. There were significant differences in complications between the two groups [OR=0.31, 95%Cl (0.13, 0.72), P=0.006]; (7) Two studies (n=97) reported ALT. There were significant differences in ALT between the two groups [SMD= – 1.54, 95%Cl (– 207, – 1.01), Plt;0.000 01]. Conclusion LH is associated with less postoperative complications, operative blood loss, duration of hospital stay and lower ALT, but longer operation time. However, the trails available for this systematic review are limited, so a prospective randomized controlled trial is warranted to fully investigate these and other outcome measures.
