Objective To evaluate result of invaginative esophagogastroanastomosis to prevent the leakage,anastomotic stenosis and reflux esophagitis in esophagectomy.Methods A method of invaginative esophagogastroanastomosis with esophageal mucus to gastric mucus and gastric seromuscular to esophagic nuscular were done in 148 cases cardiac cancer and 120 cases esophageal cancers.Gastro-esophagus full-thickness anastomosis were done in the control group including 112 cases cardiac cancer and 98 cases.Standardized rate and standard error toanalysis the date were adopted.Results It had significant difference between the two groups.Conclusion This anastomosis could avoid the esophagogastroanastomotic leakage,anastomotic stenosis and reflux esophagitis effectively.

Objective To explore the efficacy of tentorium cerebelli hiatus incision for treatment of severe brain injury complicated with tentorial herniation. Methods Tentorium cerebelli hiatus incision was performed in 38 patients of severe brain injury with secondary brain stem damage resulted from tentorial herniation after intracranial hematoma evacuation and bone flap craniotomy decompression. The changes of four sides cistern, ambient cistern and interpeduncular cistern before and after operation were observed. Results There was a siginificant difference in the appearance ratio of four sides cistern, ambient cistern and interpeduncular cistern between the preoperation and postoperation(P
