objective:to investigate the therapeutic action of somatostatin in pancreatic leakage after pancreaticoduodenectomy.methods: to collect 100 patients with pancreaticoduodenectomy during 2003～2006,contrast 44 patients use somatostatin after pancreaticoduodenectomy as experimental group,and 56 patients with conventional therapy as control group.results:there were no pancreatic leakage case in the modified group of 44 cases.3 cases complicating pancreatic leakage occurd in control group,and the proportion of pancreatic leakage are different examined by statistic mathord.conclusions:use somatostatin after pd can restrain organism excrete diastase vera,and help anastomotic stoma to concrescent and decrease pancreatic leakage;pancreatic leakage should be treated by different grades,grade 1 can be cured by persistent drainage with somatostatin and nutritional support;grade 2 should be pay more energetic intervention.
