ObjectiveTo understand the current progress of diagnosis and treatment of accidental gallbladder cancer.MethodThe relevant literatures about diagnosis and treatment of accidental gallbladder cancer and gallbladder cancer were analyzed and summarized.ResultsDue to the lack of specific symptoms and signs in most patients with accidental gallbladder cancer at the early stage, appropriate imaging examinations and tumor marker examinations could improve the preoperative diagnosis rate. The radical resection was the most effective method for accidental gallbladder cancer, but there were still some controversies about the scope of resection according to different tumor stages, the choice of laparoscopic cholecystectomy or open cholecystectomy, and the timing of reoperation. The postoperative adjuvant therapy could improve the prognosis of patients, but most patients didn’t receive adjuvant therapy after surgery.ConclusionsMost patients with accidental gallbladder cancer are in the early stage, and most of them could obtain radical resection. If the first operation fails to achieve radical resection or postoperative pathological examination to confirm the diagnosis, comprehensive evaluation of the tumor stage and the patient’s general condition should be performed, and remedial treatment should be taken as soon as possible.
ObjectiveTo systematically review the efficacy and safety of robotic-assisted hepatectomy (RAH) versus traditional laparoscopic hepatectomy (TLH) for hepatic neoplasms.MethodsDatabases including PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang Data and CBM databases were electronically searched to collect cohort studies about the RAH vs. the TLH for liver neoplasms from inception to December 10th, 2016. Two reviewers independently screened the literatures, extracted data and assessed the risk of bias of the included studies. And finally, a meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 17 studies involving 1 389 patients were included. The meta-analysis results showed that: compared to TLH group, RAH group was associated with more estimated blood loss (WMD=39.56, 95%CI 4.65 to 74.47, P=0.013), longer operative time SMD=0.55, 95%CI 0.29 to 0.80, P<0.001), and later in the first nutritional intake time (SMD=1.06, 95%CI 0.66 to 1.45,P<0.001). However, there were no significant differences in the length of hospital stay, conversion to laparotomy, intraoperative blood transfusion, resection rate of tumor margin, complications and 90-day mortality between the two groups.ConclusionCurrent evidence indicates that TLH is superior to RAH in terms of operative time, intraoperative blood loss and the first nutritional intake time, but there are no statistically significant differences in the primary outcomes, suggesting that RAH and TLH have similar efficacy and safety for hepatic neoplasms. Due to the limitation of quality and quantity of the included studies, the above conclusions need to be verified by more high-quality research.
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.
