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.
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 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.
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.
ObjectiveTo compare the advantages and disadvantages of transumbilical single port (TUSP) and conventional laparoscopic cholecystectomy (LC). MethodsThe clinical data of 45 patients underwent elective LC were analyzed, 20 patients with TUSP LC (TUSP-LC group), 25 patients with conventional LC (conventional LC group). The operation time, Child-Pugh score and painkiller application frequency within three days after operation, the first time of out of bed and hospital stay after operation, intraoperative blood loss, chronic pain within one month after surgery were compared between two groups. ResultsAll cases were operated successfully except one patient in the conventional LC group. The frequency of painkiller application within three days after operation and postoperative hospital stay in the TUSP-LC group were better than those in the conventional LC group (Plt;0.05). There were no significant differences on postoperative chronic pain of surgical area within 1 month and Child-Pugh score between two groups (Pgt;0.05). The operation time and intraoperative blood loss in the conventional LC group were less than those in the TUSP-LC group (Plt;0.05, Plt;0.01). ConclusionTUSP LC has the advantages of small wound, slight pain, and fast recovery.
Objective To discuss the pathogeny， treatment and prophylactic measures of postcholecystectomy syndrome (PCS). Methods The clinical data of 150 patients with laparoscopic PCS in our department from October 2000 to March 2009 were analyzed. Results Etiological factors were found in 131 patients: one hundred and twelve cases were due to the reasons of biliary system, including bile duct residual stones after cystic resection， the injury bile duct stenosis， a long residual cystic canal， nipple benign stricture, bile duct tumor etc; Nineteen examples were due to other reasons, including gallbladder stone merger reflux gastritis, gastroduodenal ulcer， diverticulum beside duodenal nipple, and so on, which resulted in the symptoms un-release after cystic resection. Nineteen cases were not found organic lesion. In ones whose etiological factors were definite, 117 cases were treated with different surgeries according to different etiological factors; another 33 cases were treated with conservative treatment. Total 145 cases were followed up, and 139 cases in them were cured or relieved at different degrees. Conclusion Careful preoperative examination, normalized operation avoiding damaging bile duct and leaving behind bile duct stones can effectively prevent laparoscopic PCS.
【Abstract】Objective To evaluate the operation of laparoscopic splenectomy（LS）, its safety and clinical effects.Methods Literature of the advances of LS were reviewed and analyzed.Results With the development of technology and surgical technique, the indications for LS were widened, the size of spleen plays an important role in the clinical outcome of LS.Conclusion LS has all the advantages of minimally invasive surgery.

【Abstract】Objective To investigate prophylactic measures for nontraumatic complications of laparoscopic cholecystectomy (LC).Methods The data of 13 000 patients who underwent LC in Kunming general hospital of PLA over 13 years(1991-2004) were retrospectively reviewed. Results Nine malignant tumors and 47 common bile duct stones were missed at LC. The 9 malignant tumors included hepatic cancer (n=1), gastric cancer (n=1), gallbladder cancer (n=2), pancreatic cancer (n=2) and right colon cancer (n=3). Of all the carcinomas, 3 patients with right colon cancer underwent colectomy, the other 6 patients couldn’t be cured radically. All the 47 patients with choledocholithiasis were cured successfully, among them 31 patients were performed with ERCP and 16 were reoperated on with cholangiotomy. Conclusion This study emphasizes the necessity to analyze carefully patients’ symptoms before operation and pay attention to pathological changes of gallbladder and intraabdominal situation intraoperatively. If necessary, laparoscopic ultrosonography can be used to avoid missing malignant tumors and biliary stones.
