ObjectiveTo systematically review safety and effectiveness of robotic Roux-en-Y gastric bypass (RYGB) and laparoscopic RYGB for morbid obesity.MethodsThe systematic literatures were conducted by a comprehensive search in the PubMed, Embase, Cochrane Library, WanFang data, CNKI, and CBM, etc. Two reviewers independently selected the literatures and extracted the data. The meta-analysis was performed using the R statistical program version 3.4.2.ResultsA total of 19 studies involving 177 766 patients with morbid obesity were included, of which 172 234 underwent the laparoscopic RYGB (laparoscopic group) and 5 532 underwent the robotic RYGB (robotic group). The operative time was longer [MD=27.84, 95% CI (12.85, 42.83)] and the rate of death was higher [OR=2.05, 95% CI (1.03, 4.08)] in the robotic group as compared with the laparoscopic group. The hospitalization time, intraoperative blood loss, conversion rate, rates of reoperation and readmission of 30 d after the operation, and postoperative complications had no significant differences between these two groups.ConclusionRobotic RYGB is a safe and effective surgical procedure, but it is not found to be superior to laparoscopic RYGB.
ObjectiveTo compare the clinical effects of two commonly used organ preservation solutions University of Wisconsin (UW) solution and histidine-tryptophan-ketoglutarate (HTK) solution in liver transplantation.MethodsThe PubMed, Embase, Cochrane Library, CNKI, CBM, VIP, and Wanfang Data were searched to collect the comparative studies of the UW solution and HTK solution in the liver transplantation. The data were extracted and evaluated by the RevMan 5.3 software.ResultsFinally, 16 articles with a total of 35 024 patients were included. The meta-analysis results showed that the HTK solution group had a lower incidence of postoperative biliary complications [RR=1.30, 95%CI (1.07 1.58), P=0.008] and lower aspartate aminotransferase peak level within 7 d after operation [MD=112.45, 95%CI (93.34, 131.56), P<0.01] as compared with the UW solution group. No significant differences were found in terms of the incidence of primary non-function [RR=1.07, 95%CI (0.52, 2.18), P=0.86], survival rates of patient and graft in different time points (P>0.05), incidence of retransplantation [RR=0.83, 95%CI (0.48, 1.45), P=0.51], incidence of acute rejection [RR=1.27, 95%CI (0.96, 1.68), P=0.33], alanine aminotransferase peak level within 7 d [MD=31.79, 95%CI (–161.84, 225.42), P=0.75] after operation, total bilirubin [MD=19.42, 95%CI (–10.83, 49.67), P=0.21], and prothrombin time [MD=1.75, 95%CI (0.01, 3.49), P=0.84] between these two groups.ConclusionsHTK solution is safe and effective for liver transplantation, and has similar effects as UW solution. Regarding effect of both on long-term survival rates of patient and graft, large-sample and high-quality RCT is still needed for systematic evaluation.
ObjectiveTo summarize the application status and related progress of robot-assisted technology in general surgery.MethodThe related researches about robot-assisted technology in general surgery in recent year were searched and reviewed.ResultsRobot-assisted techniques had similar safety and effectiveness to endoscopic surgery in general surgery. In addition, in rectal cancer, thyroid and pancreatic surgery, due to the narrow operation space, the advantages of robot-assisted surgery was more obvious.ConclusionsThe application of robot-assisted techniques in general surgery is safe and effective. With the decrease of the cost of robotic surgery, which has wide application value in general surgery.
