ObjectiveTo systematically review the efficacy and safety of laparoscopic versus open nephrectomy in the treatment of autosomal dominant polycystic kidney disease (ADPKD). MethodsWe searched databases including MEDLINE, EMbase, The Cochrane Library (Issue 1, 2015), Web of Science, CBM and WanFang Data to collect relevant clinical studies comparing the efficacy and safety of laparoscopic versus open nephrectomy for ADPKD from inception to Jan, 2015. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies. Then, RevMan 5.4 software was used for meta-analysis. ResultsA total of six retrospective cohort studies involving 182 patients were included. The results of the meta-analysis showed that:compared with the open nephrectomy group, the average hospitalization time was shorter (MD=-4.38 days, 95%CI -5.93 to -2.83, P=0.000 01) and the blood transfusion risk was lower (OR=0.25, 95%CI 0.10 to 0.62, P=0.003) in the laparoscopic nephrectomy group. However, there was no significant difference between two groups in the incidence of overall complications (OR=0.51, 95%CI 0.24 to 1.06, P=0.07). ConclusionThe application of laparoscopic nephrectomy for ADPKD can reduce the hospitalization time and blood transfusion risk when compared with the open nephrectomy, but the two operations have similar overall complication rate. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To summarize the current progress in diagnosis and treatment of polycystic liver disease, and provide ideas for further research direction and clinical practice of polycystic liver disease. Method The domestic and foreign literature about polycystic liver disease was reviewed, screened, and summarized. Results The diagnosis, evaluation, and classification of polycystic liver disease were mainly performed clinically by abdominal ultrasound and CT. Surgical treatment was the main treatment, including aspiration sclerotherapy, fenestration, segmental hepatectomy, and liver transplantation. Conclusions The classification and evaluation scheme of polycystic liver disease needs to be improved, and its medical treatment still needs further research. Estrogen receptor and gonadotropin-releasing hormone receptor are promising therapeutic targets.
