RESUMO
Gastric cancer is one of the most common malignant tumors in the world, and its incidence and mortality are among the top of malignant tumors in China. Since Kitano et al com-plete the first laparoscopic radical gastrectomy for gastric cancer in the world in 1992, the laparos-copic technology has developed rapidly. After more than 30 years of exploration and practice, the clinical diagnosis and treatment of gastric cancer in China has also made considerable progress. A large number of clinical studies at home and abroad have confirmed that laparoscopic radical gas-trectomy is no less effective than traditional open surgery in the short and long term. Laparoscopic radical gastrectomy has the characteristics of less trauma, faster recovery of gastrointestinal func-tion, less postoperative pain, and shorter average hospital stay. It has gradually replaced open surgery as the mainstream surgical method for gastric cancer. As the concept of surgical treatment for gastric cancer continues to update, emerging minimally invasive technologies continue to emerge, including robotic surgery systems and indocyanine green tracing technology, which are increasingly used in gastric cancer surgery, making gastric cancer surgery more minimally invasive and accurate, the quality of perigastric lymph node dissection and the domestic gastric cancer surgery technology further improving. Based on the relevant research at home and abroad, the authors review and summarize the latest progress in recent years with the topic of minimally invasive surgery for gastric cancer, aiming to systematically describe the current situation and future prospects of gastric cancer surgery. It is believed that in the future, the clinical diagnosis and treatment of gastric cancer in China will be more standardized, minimally invasive and accurate, more high-quality multicenter clinical research will be carry out and the diagnosis and treatment of gastric cancer will be further improved in China.
RESUMO
Objective To investigate the correlation of right ventricular wall fatty infiltration or fibrosis degree and function and volume of right ventricle in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC).Methods Twenty ARVC patients were enrolled.Multi-sequences of MR scanning were performed,and the transverse diameter of outflow tract of right and left ventricle,end-diastolic dimension (EDD),ejection fraction (EF),end-diastolic volume index (EDVI),end-systolic volume index (ESVI),cardiac output index (CI),as well as right ventricular myocardial mass index (MASSI) and fat and fibrosis tissue characteristics were quantitatively evaluated.The correlation between right ventricular wall fatty infiltration or fibrosis and right ventricular function and volume were analyzed.Results The right ventricular outflow tract transverse diameter was (52.42±11.80)mm,and right ventricular EDD,EF,EDVI,ESVI,CI and MASSI was(50.13 ± 8.71) mm,(18.13± 6.71)％,(169.13 ± 72.11) ml/m2,(117.01 ± 67.31) ml/m2,(1.81±0.20) L/(min · m2) and (17.62 ±1.80)ml/m2,respectively.The right ventricular free wall/anterior wall involvement was observed in all 20 cases,while inferior wall involvement,apical involvement and right ventricular outflow tract involvement was noticed in 10,14 and 15 cases,respectively.The right ventricular wall fat infiltration or fibrosis index was (70.00±22.33) ％,correlated with right ventricular EF (r=-0.627,P =0.003),EDVI (r=0.695,P=0.001)) and ESVI (r=0.676,P=0.001).Conclusion The correlation of right ventricular wall fatty infiltration or fibrosis degree and function and volume of right ventricle may reflect changes of cardiac function in ARVC patients.
