Objective To assess the effectiveness and safety of hand-suture vs. stapling anastomosis in esophagogastrostomy. Methods The following databases such as CBM (1978 to February 2012), VIP (1989 to February 2012), CNKI (1994 to February 2012), WanFang Data (1980 to February 2012), The Cochrane Library, PubMed (1966 to February 2012), EMbase (1974 to February 2012), and relevant webs of clinical trials were searched to collect the randomized controlled trials (RCTs) and quasi-RCTs about hand-suture vs. stapling anastomosis in the incidence of anastomotic leakage following esophagogastrostomy. Moreover, relevant references and grey literature were retrieved on web engines including Google Scholar and Medical Martix, and the Chinese periodicals e.g. Chinese Journal of Oncology were also handsearched. According to the inclusion and exclusion criteria, the literature, was screened, the data were extracted, and the quality of the included studies was assessed. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 9 RCTs involving 2 202 patients were included. The result of meta-analysis was as follows: the incidence of anastomotic leakage in the stapling anastomosis group was lower than that in the hand-suture anastomosis group (OR=0.43, 95%CI 0.26 to 0.71, Plt;0.01). Conclusion Stapling anastomosis is superior to hand-suture anastomosis in reducing the incidence of anastomotic leakage following esophagogastrostomy. For the limited quality and quantity of the included studies, this conclusion has to be further proved by more high-quality studies.
The announcement of the 9th edition of TNM staging system for thymic tumors was one of the highlights at the World Conference on Lung Cancer 2023. The revision, based on a larger and more detailed database, provides changes and confirmation from the last system. The 9th edition of TNM staging system aims to balance statistical significance and clinical feasibility. The birth of an improved TNM staging system heralds the changes that will follow in clinical practice and scientific research.
