ObjectiveTo systematically review the efficacy and safety of laryngeal mask versus endotracheal tubes for laparoscopic surgery.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect the randomized controlled trials (RCTs) about the efficacy and safety of laryngeal mask versus endotracheal tubes for laparoscopic surgery from inception to April, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 16 RCTs involving 1 593 patients were included. The results of meta-analysis showed that: there was no significant difference in the success rate of the first insertion (RR=0.99, 95%CI 0.96 to 1.02, P=0.55). The airway pressure of patients whose position were head higher than foot was significantly lower in the laryngeal mask group than in the tracheal intubation group (MD=–1.20, 95%CI –1.81 to –0.59, P=0.000 1), but there was no significant difference between two groups in reverse position patients (MD=0.48, 95%CI –0.90 to 1.87, P=0.49). The incidence of sore throat (RR=0.58, 95%CI 0.46 to 0.74, P<0.000 01), the incidence of blood stain (RR=0.48, 95%CI 0.30 to 0.77, P=0.002), the incidence of laryngeal spasm/bronchial spasm (OR=0.30, 95%CI 0.11 to 0.80, P=0.02) and the incidence of cough/hiccup (RR=0.10, 95%CI 0.07 to 0.15, P<0.000 01) in the laryngeal mask group were significantly lower than those in the tracheal intubation group.ConclusionThe current evidence shows that compared with tracheal intubation, laryngeal mask can effectively reduce airway pressure of patients whose position are head higher than foot. The risks of various complications are significant higher in tracheal intubation in laparoscopic surgery. Laryngeal mask can maintain patients' normal respiratory functions while reduce damage and do not increase the occurrence of reflux aspiration. Due to limited quantity and quality of the included studies, more high quality studies are needed to verify above conclusion.
From December 1995 to December 1997, 1 500 patients with gallstones or together with biliary duct stones accepted laparoscopic cholesystectomy (LC) or LC+laparoscopic common bile duct exploration (LCDE). There were 9 had serious complications (0.6%) occured . While the mean age was 54.9 years old. The sex ratio (female∶male) was 1∶1.25. Three cases had major biliary duct disruption, 1 case had stomach perforation, 2 cases had duodenal injuries, 1 bleeding case because cystic artery fail to clip, 1 case had postoperative cystic duct leak, and 1 case with T-tube dislodgement. All complications had been discovered during or shortly after operations. The injuries on the extrahepatic biliary duct with lengths of 0.2-0.4cm, and the gastrodenal injuries sized 0.5-1.0cm. All of the injuries had been sutured laparoscopically without sequela. The one who had postoperative cystic duct leak and jaundice accepted LCDE, proved to have a common bile duct stone. The bleeding cystic artery had been clipped well, and the dislodged T-tube replaced well. The results show if the complications which may be very serious or complex had been discovered shortly after or during the operations, its can be managed with laparoscopic technique safely by experienced operators.
ObjectiveTo investigate the feasibility and advantages of general laparoscopic cholecystectomy and gynecologic uterus and attachment surgery at the same time. MethodsSixty patients with gallbladder stones combined with ovarian cysts, benign gynecological disease or fallopian tube adhesions aged between 35 and 55 were chosen from the department of General Surgery and Gynecology and Obstetrics to be the study subjects between January 2009 and December 2013. The inclusion criteria included: gallbladder stones; gallbladder wall thickness <0.5 cm; non-acute inflammation; symptomatic gynecological diseases; and tumor size between 5.0 and 10.0 cm. Based on similar age, body mass, and histological type, the patients were divided into laparoscopic surgery (GLS) group and staging surgery group (control group) according to the will of the patients. The anesthesia time, surgery time, the number of abdominal perforations, length of hospital stay, and total costs were detected for comparison between the two groups. ResultsThe first-time operation was successful in all the patients in the CLS group, with two cases of abnormal liver function, which were cured within 5-6 days. In the control group, 2 cases of reoperation were transferred to laparotomy due to umbilical and peritoneal adhesions, and both of them were cured and discharged from hospital without incision infection or iatrogenic tissue and organ damage. CLS group had significant advantages in anesthesia time, surgery time, the number of abdominal perforations, length of hospital stay, and total costs over the control group (P<0.05). ConclusionThe combined gynecologic laparoscopic surgery is feasible, safe, mini-invasive, and economical.
ObjectiveTo summary the standard treatment for early gastric cancer. MethodsThe current early gastric cancer treatment guidelines around the world were analyzed and the standardized treatment patterns for early gastric cancer were concluded. ResultsThe accurate preoperative evaluation for early gastric cancer is the basis of standardized treatment which can be divided into staging evaluation and histological evaluation.The staging evaluation is focused on the gastric wall invasion and lymph node involvement of the tumor while the histologic evaluation emphasize the histological type and grading of the tumor.According to the precise evaluation for early gastric cancer, endoscopic surgery, laparoscopic surgery, open surgery, and multimodal therapy can be applied individually to the patients.Different treatment methods have their indications, but the indications of the therapies in different guidelines are suggested with slight differences. ConclusionIn clinical practice, the choice of treatment should be made with comprehensive consideration of diagnosis and individual characteristics of patients to achieve the most benefit on prognosis.
Objective To investigate the feasibility and safety of laparoscopic-assisted gastrectomy for distant gastric cancer. Methods All 18 patients with distant gastric cancer receiving laparoscopic-assisted gastrectomy were analyzed. Results Laparoscopic-assisted distal gastrectomy was performed successfully in all patients. The mean operation time was (291.33±19.61) min. The mean blood loss was (151.32±71.78) ml. The mean numbers of harvested lymph node were 14.57±3.11. The mean time of gastrointestinal function recovery was (3.46±0.93) d, the mean out of bed activity time was (1.75±0.45) d. All patients were followed up for 1-24 months, mean 11 months. No local recurrence, trocar implant or distant metastasis happened. Conclusion Laparoscopic-assisted gastrectomy is a feasible and safe surgical procedure combined with minimal trauma and fast recovery.
ObjectiveTo analyze the effect and prognosis of laparoscopic patch repair of esophageal hiatal hernia.MethodsFrom October 2014 to January 2019, 100 patients with gastroesophageal reflux disease undergoing laparoscopic esophageal hiatus hernia repair were randomly divided into the patch group and the non-patch group. All patients underwent laparoscopic repair of esophageal hiatal hernia plus fundoplication (Nissen’s method). On that basis, the patients in the patch group used special mesh for esophageal hiatal hernia repair, while the ones in the non-patch group did not. All the patients were followed up for a long time. The operative effect, postoperative complication rate, recurrence rate, and satisfaction rate of the patients between the two groups were compared.ResultsA total of 98 patients were successfully followed up for more than one year, including 68 in the patch group and 30 in the non-patch group. One year after surgery, the differences between the patch group and the non-patch group in the improvements of reflux attack, heartburn, dysphagia, and food intake were statistically significant (P<0.05); there was no significant difference between the patch group and the non-patch group in satisfaction rate (82.4% vs. 73.3%, P>0.05); the differences in recurrence rate (2.9% vs. 26.7%) and incidence of dysphagia (47.0% vs. 6.7%) between the patch group and the non-patch group were statistically significant (P<0.05).ConclusionFor the patients with gastroesophageal reflux disease caused by esophageal hiatal hernia, the laparoscopic repair of esophageal hiatal hernia + Nissen fundoplication on the basis of reasonable selection of special mesh for esophageal hiatal hernia can obtain satisfactory clinical effect.
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 systematically review the influence on ovarian reserve function by different hemostatic methods during laparoscopic cystectomy in treatment of ovarian endometrioma (OE). MethodsDatabases including The Cochrane Library, PubMed, EMbase, CNKI, CBM and WanFang Data were electronically searched, to collect relevant randomized controlled trials (RCTs) about laparoscopic electro coagulation vs. microscopically suture for OE from 1990 to Mar, 2014. Meanwhile, references of included studies were also retrieved manually. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the risk of bias of included studies. Then RevMan 5.2 software was used for meta-analysis. ResultsA total of 16 RCTs involving 1 236 patients were finally included. The results of meta-analysis showed that the luteinizing hormone (LH) levels after 1 month, 2 months, 6 months and 12 months and estradiol (E2) levels after 2 months, 6 months had no significant differences between the two groups and the E2 level after 12 month of the suture group was significantly lower than that of the electro coagulation group. The levels of follicle stimulating hormone (FSH), LH, E2, antral follicle count (AFC), mean ovarian stromal peak systolic blood flow velocity (PSV) and anti-Mullerian hormone (AMH) in the suture group were significantly superior to those in the electro coagulation group at other follow-up time. ConclusionCurrent evidence suggests that in treatment of ovarian endometriotic cyst by laparoscopic cystectomy, compared with electro coagulation hemostasis, suture hemostasis has less influence on ovarian reserve function. Due to limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusion.
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.
