The Evaluation Of Fluid Absorption Monitoring Of Endoscopic Surveillance System The Effectiveness And Safety Of Laparoendoscopic Single-site Surgery For Varicocele:a Systematic Review

Objective Evaluating the accuracy and consistency of the endoscopic surveillance system regarding fluid deficit and hemorrhage monitoring in simulation trials, in order to provide a basis for clinical trials.Method We conducted the accuracy testing trial including repetition and increment experiments for irrigation fluid metering system and blood measuring system. Recorded and analyzed the measuring and standard values in order to verify the accuracy and consistency of the unit of the endoscopic surveillance system. In vitro simulation trials, we did the repetition and increment experiments for fluid deficit and hemorrhage detection by simulating the fluid absorption and hemorrhage in the operation, and recorded and analyzed the measuring and standard values in order to verify the the accuracy and consistency of the endoscopic surveillance system.Result The experiment shows that irrigation fluid metering system and blood measuring system is accurate and stabe for all sorts of flushing fluid, and variance exists between different flushing fluid. In vitro simulation trials,the accumulation of flushing fluid may have some effect on the accuracy and consistency of the endoscopic surveillance system,but the blood detecting probe has very excellent performance.Conclusion The endoscopic surveillance system can accurately and stably measure the amount of fluid absorption and blood loss in the endoscopic surgery, and support the surgery information for the surgeon in order to reduce the surgical complications. some improvements should be done to get a more precise measurement. Objective To systematically review the ef ectiveness and safety of laparoendoscopic single-site surgery (LESS) for varicocele.Method Such databases as The Cochrane Library, MEDLINE, EMbase, CBM, CNKI, and WanFang Data were electronically searched for studies about LESS and traditional laparoscopy for varicocele till March1st,2013. According to the inclusion and exclusion criteria, literature was screened, data were extracted, and the methodological quality of included studies was also assessed. Then, meta-analysis was performed using RevMan5.1sotware。Result Seven RCTs involving452cases were included. The results of meta-analysis showed that, there was no significant difference between LESS and traditional laparoscopy for varicocele on post-operational complications (RR=0.57,95%CI0.26to1.27, P=0.17), duration of hospital stay (MD=-0.30,95%CI-0.87to0.26, P=0.30), improvement of semen parameters, and blood loss. However, LESS had longer duration of operation (MD=11.26,95%CI3.62to18.90, P=0.004)Conclusion The effectiveness and safety of LESS and traditional laparoscopy for varicocele are similar, and LESS could achieve more beautiful and natural effects which has longer surgery time on account of non-proi ciency in surgery and equipment. Due to the limited quantity and quality of the included studies, the above conclusion requires to be proved by more high quality randomized controlled trials.
