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.
ObjectiveTo summarized the clinical experience on laparoscopic radical surgery in patients with advanced distal gastric cancer. MethodsThe clinical data of 26 patients with advanced distant gastric cancer undergoing laparoscopic gastrectomy were retrospectively analyzed. ResultsLaparoscopic distal gastrectomy was performed successfully in all patients. The operation time was (283.2±27.6) min (270-450 min) and the blood loss was (178.4±67.4) ml (80-350 ml). The time of gastrointestinal function recovery was (2.8±1.2) d (2-4 d), out of bed activity time was (1.5±0.4) d (1-3 d) and liquid diet feeding was (3.5±1.4) d (3-4 d). The hospital stay was (10.0±2.6) d (7-13 d). The number of harvested lymph nodes was 11 to 34 (17.8±7.3). The distance from proximal surgical margin to tumor was (7.0±2.1) cm (5-12 cm) and the distance from distal surgical margin to tumor was (5.5±1.8) cm (4-8 cm), thus surgical margins were negative in all samples. All patients were followed up for 3-48 months (mean 18.5 months), two patients with poorly differentiated adenocarcinoma died of extensive metastasis in 13 and 18 months, respectively, and other patients survived well. ConclusionsLaparoscopic radical gastrectomy with D2 lymphadenectomy for advanced gastric cancer is safe and feasible. However, the advantage of laparoscopic technique over the conventional open surgery requires further study.
Objective To investigate the feasibility and safety of laparoscopic operation of gastric and gastroesophageal junction diseases. Methods Between May 2004 and June 2009, 59 patients with gastric and gastroesophageal diseases were treated laparoscopically. The operative methods and maneuvers were evaluated and perioperative interventions, complications and efficacy of patients were analyzed. Results All operations were successfully completed laparoscopically except for one patient with gastric cancer who required a conversion to open surgery. No short-term complications occurred in all cases. No port transplant metastasis occurred for the patients with gastric cancer after an average of 36 months (1-60 months) follow-up. One patient died of liver metastasis 12 months after operation. The 3-year survival rate was 93.3% (14/15). Conclusion Laparoscopic surgery of the gastric and gastroesophageal junction diseases is feasible and safe with minimal invasiveness, which is worth popularizing.
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.
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 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.
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 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.
ObjectiveTo investigate the efficacy and safety of laparoscopic surgery for overweight/obese patients with acute perforated or gangrenous appendicitis. MethodsFrom January 2007 to December 2014, patients with acute perforated or gangrenous appendicitis underwent laparoscopic (152 cases) or open (60 cases) appendectomy were collected, who were retrospectively classified into overweight/obese group (BMI≥25 kg/m2, n=69) or normal weight group (BMI < 25 kg/m2, n=143). Conversion rate, operation time, hospital stay, readmission, reoperation, and postoperative complications such as incision infection, abdominal abscess, and lung infection were analyzed. Results①The rate of conversion to open surgery had no significant difference between the overweight/obese group and the normal weight group[4.2% (2/48) versus 6.7% (7/104), χ2=0.06, P > 0.05].②The operation time of laparoscopic surgery in the overweight/obese group was significantly shorter than that of the open surgery in the overweight/obese group[(41.6±11.7) min versus (63.1±23.3) min, P < 0.01], which had no significant difference between the laparoscopic surgery in the overweight/obese group and laparoscopic surgery in the normal weight group[(41.6±11.7) min versus (39.6±12.7) min, P > 0.05].③The total complications rate and incision infection rate of the laparoscopic surgery in the overweight/obese group were significantly lower than those of the open surgery in the overweight/obese group[total complications rate:16.7% (8/48) versus 52.4% (11/21), χ2=9.34, P < 0.01; incision infection rate:4.2% (2/48) versus 33.3% (7/21), χ2=8.54, P < 0.01]. Although the total complications rate of all the patients in the overweight/obese group was increased as compared with all the patients in the normal weight group[27.5% (19/69) versus 14.7% (21/143), χ2=5.02, P < 0.01], but which had no significant difference between the laparoscopic surgery in the overweight/obese group and laparoscopic surgery in the normal weight group[16.7% (8/48) versus 12.5% (13/104), χ2=0.45, P > 0.05].④The reoperation rate of all the patients performed laparoscopic surgery was significantly lower than that of all the patients performed open operation[1.3% (2/152) versus 10.0% (6/60), χ2=6.7, P < 0.01].⑤The abdominal abscess rate, lung infection rate, and hospital stay after discharge had no significant differences among all the patients (P > 0.05). ConclusionLaparoscopic appendectomy could be considered a safe technique for overweight/obese patients with acute perforated or gangrenous appendicitis, which could not increase the difficulty of laparoscopic surgery and the perioperative risk.
ObjectiveTo evaluate the safety and clinical effect of laparoscopic Miles and perineal anal recon-struction operation for patients with low rectal cancer. MethodsOne hundred and two patients underwent Mile's and perineal anal reconstruction operation for rectal cancer in this hospital from April 2006 to February 2010 were analyzed retrospectively, in which 58 patients underwent laparoscopic surgery (laparoscope group) and 44 patients underwent open surgery (laparotomy group).All these data such as the survival time, operative time, intraoperative blood loss, harvested lymph nodes, the first anal exhaust time and liquid diet recovery time after operation, postoperative hospitalization, and postoperative complications were collected and compared between the laparoscope group and laparotomy group. ResultsThe demography and clinicopathologic characteristics were similar between these two groups (P > 0.05).The operation was successfully performed in all the patients.There was no death associated with the operation.Compared with the laparotomy group, the intraoperative blood loss was less (P < 0.05), the first anal exhaust time and liquid diet recovery time after operation, postoperative hospitalization were shorter (P < 0.05), the harvested lymph node was more (P < 0.05) in the laparoscope group.There were no significant differences in the operative time, postoperative complications, and the survival curves between the two groups (P > 0.05). ConclusionsThe clinical effects of laparoscopic and open Miles and perineal anal reconstruction operation are similar for patients with low rectal cancer.But laparoscopic operation is a safe, feasible choice with quicker recover after the operation.
