RÉSUMÉ
Objective To evaluate the safety and efficacy of ligasure vessel sealing system (LVSS) and conventional ligation haemostasis in thyroidectomy.Methods Pubmed,EMBASE,Medline,and CNKI were performed to search for randomized controlled trial.Literature selection and data collection were completed by 2 researchers independently.The assessment of methodological quality was conducted with Cochrane Handbook 5.1.The Review Manager software 5.2 was used for Meta analysis.Results A total of 11 studies (934 patients) were involved.Meta-analysis indicated that the operation time was shorter in LVSS group [WMD=-12.47,95％ CI (-18.33,-6.61),P＜0.0001].No significant difference was found in intra-operative blood loss,incidence of hypocalcaemia,recurrent laryngeal nerve (RLN) injury,or hospitalization time between the 2 groups (P＞0.05).Conclusion LVSS can reduce the operation time without increasing intra-operative blood loss,incidence of hypocalcemia,RLN injury,or hospitalization time,which is a safe and effective haemostasis method.

Objective To investigate the value of LigaSure vessel sealing system for surgery in gastroenteric cancer. Methods From January to September 2009,44 cases of gastroenteric cancer were operated by using LigaSure vessel sealing system,including 13 cases of gastric cancer, 14 cases of colon cancer, 17 cases of rectum cancer. Laparoscopy was employed in 10 cases. Results All the cases were performed successfully. The operation time was 130-250 min, the blood loss was 50-250 ml, and the number of lymph nodes resected was 4-20. None of the cases had serious complications. Conclusion As an optimal hemostatic tool, LigaSure vessel sealing system is safe and feasible for gastroenteric cancer.

Objective To explore the value of Ligasure vessel sealing system(LVSS)during resection of retroperitoneal tumor.Methods Group 1 including 32 cases were performed resection of retroperitoneal tumor with LVSS and electrosurgical seapel from Jun.2004 to Oct.2008.group 2 including 26 cases were done with electrosurgieal seapel from Jan.2001 to Jun.2004.Operating blood loss,operating time,iatrogenic injury,postoperative blood loss and hospital stay were compared between the two groups.Results There was no significant difference in hospital stay[(11.7±0.7)d vs.(12.3±1.4)d)]and iatrogenic injury(9.38%vs.16.00%)between two groups statistically(P＞0.05),but the intraoperative blood lose[(403.1±37.1)ml vs.(704.0±129.0)m1)s,postoperative blood loss[(131.5±18.4)ml vs.(214.8±29.2)ml)]and operating time[(166.5±8.9)min vs.(186.8±15.4)min]were less in group 1 than that in group 2(P＜0.05).Conclusion Ligasure vessel sealing system has advantages of safe coagulation,shortening operation time in resection of retroperitoneal tumor.

Objective To explore the value of the LigaSure vessel sealing in laparoscopic nephrectomy surgery. Methods Laparoscopic nephreetomies were performed in 41 cases from May 2004 to December 2006 by using LigaSure, including simple nephrectomies, radical nephrectomies and nephroureterectomies. The operative time, estimated blood loss, open conversion rate, duration of postoperative drainage, total amount of postoperative drainage, postoperative hospital day as well as complication rate were recorded and analyzed retrospectively. Results All procedures were finished successfully without conversion to open surgery. No severe vascular complication or other serious complications happened. The mean operative time was 146min (range, 35-240 min) ; mean blood loss was 163ml (range, 30-450 ml); mean time for postoperative drainage was 3d (range, 1-6 d) ; mean amount of postoperative drainage was 229ml (range, 45-435 ml). The postoperative hospital staying was 6-21 d, with the average of 10 days. Conclusions The LigaSure vessel sealing system produees a consistent, reliable, permanent seal of veins, arteries, and tissue bundles. It could decrease operative time and blood loss. This new energy-based vessel-ligation device appears to be effective in advanced laparoscopic procedures.

Objective To investigate the clinical efficacy of LigaSure vessel sealing system(LVSS)in laparoscopic splenectomy(LS).Methods From August 2005 to September 2006,11 cases underwent LS with LVSS.LVSS was applied to cut off lienocolic ligament and gastrosplenic ligament,and separate splenic artery from the superior border of spleen tail and blocked by an absorbable clip,and then splenic stalk was separated and cut off near the hilum of spleen with LVSS.Results LS was successfully completed in 10 cases,in which 9 with LVSS entirely,and 1 case used Endo-GIA due to difficulties in splenic stalk separation.And one case was converted to laparotomy for close adhesion of spleen with the surrounding tissues.The operation time was 60-150 min,110 min in average;blood loss was 80-400 ml.No complications such as postoperative massive hemorrhage,pancreatic leakage,or gastric leakage occured.Conclusions Application of LVSS in LS is characterized by safety,reliable hemostasis,and leaving no internal foreign body.
RÉSUMÉ
Objective To explore the value of Ligasure and Ultracision in total laparoscopic hysterectomy (TLH). Methods From January 2002 to December 2006,totally 225 patients received total laparoscopic hysterectomy in our hospital. Among the cases,Ligasure was used in 152 patients,and Ultracision were employed in 72. The clinical data of the patients were reviewed. Results The mean operation time in the Ligasure group was significantly shorter than that in the Ultracision group [(104.9?29.2) min vs. (152.4?46.6) min,t=-9.329,P=0.000]. And the mean blood loss of the Ligasure group was significantly less than that in the other group [(32.9?14.9) ml vs. (126.4?12.1) ml,t=-46.710,P=0.000]. In both the groups,no patient was converted to open surgery or developed complications or surgical injuries. Conclusions Both Ligasure and Ultracision are safe and effective for total laparoscopic hysterectomy. Ligasure is superior in the management of uterine vessels,while the Ultracision is more effective in opening the vesicle and separating the cardinal ligament.
RÉSUMÉ
Objective To evaluate the usefulness of the LigaSure vessel sealing system for vascular control during transvaginal hysterectomy and compared it with suture group. Methods One hundred and sixty-one transvaginal hysterectomy were performed with LigaSure while 62 with traditional suture from Sept 2002 to Mar 2003. Meanwhile, the operating time, the estimated blood loss, the postoperative recovery and hospital stay were explored. Results All of the surgery were successfully performed with both LigaSure and traditional suture. Compared with suture group the LigaSure has many advantages in operating time, estimated blood loss and postoperative recovery. Conclusion For transvaginal hysterectomy LigaSure vessel sealing system is a more useful instrument and also an ideal option. It may be used safely in large, difficult uterus during transvaginal hysterectomy with less blood lose, short operating time, quick recovery after surgery.
