BACKGROUNDTo study the significance of pneumonectomy via intrapericardial vascular management in the surgical treatment of lung cancer.

METHODSA total of 56 patients with central-type lung cancer underwent pneumonectomy via intrapericardial vascular management.

RESULTSThe incidence of postoperative complications was 8.93%(5/56). One patient died and the mortality rate was 1.97%. The postoperative follow up rate was 96.4%. The 1-, 3- and 5-year survival rates were 72.7%(40/55), 31.4%(11/35) and 17.4% (4/23) respectively.

CONCLUSIONSPneumonectomy via intrapericardial vascular management is safe and can improve the resection rate. It might provide a basis for the further treatment of lung cancer and should be widely applied.

Objective To explore the feasibility of gastroesophagostomy when patients with esophagus carcinoma com bined with stomach carcinoma.Methods In March 2011 to May 2016,our department completed with the method of genera tion of esophagus stomach in the treatment of esophageal cancer merger 18 cases of gastric cancer patients.Age 52-67,16 ca ses of esophageal lesions located in the middle section,2 cases located in the chest.4 cases were gastric lesions located in the proximal stomach,14 cases were located in the distal stomach Four kinds of surgical methods can be chosen from.Proximal or distal stomach could be used to replace esophagus and the blood supply came from left gastric artery or right gastroepiploic artery.Stomach tissue separation and reverse gastric tube were used if the length of stomach was insufficieut.Results When resection of esophageal and gastric carcinoma were accomplished simultaneously,residue stomach can be used as a replacement of esophagus if patients were rigidly selected.Conclusion Residue stomach was a good substitute after radical resection of esoph agus and gastric dual-source carcinoma.Patients chosen and surgery design were both important.

Clinical experiments are always used to evaluate the safety and validity of medical devices. The experiments have two types of clinical trying and testing. Ethic review must be done by the ethics committee of the medical department with the qualification of clinical research, and the approval must be made before the experiments. In order to ensure the safety and validity of clinical experiments of medical devices in medical institutions, the contents, process and approval criterions of the ethic review were analyzed and discussed.
