Abstract: OBJECTIVE: To investigate effects of ulinastatin in combination with metal biliary stent on pancreatic cancers which were caused by extrahepatic biliary obstruction. METHODS: A total of 92 pancreatic cancer patients with extrahepatic biliary obstruction were selected and ewually divided into control and observation groups according to the random number table method. The control group was treated with metal biliary stent implantation alone,and the observation group was treated in combination with ulinastatin for two weeks. Before and after the treatments,concentrations of liver function total bilirubin (TBiL) and aspartate aminotransferase (AST),and changes of blood uric acid (UA) and urea nitrogen (BUN) were determined. In addition,clinical efficacy and occurrence of adverse reactions after the treatment were compared between the two groups. RESULTS: After the treatment,AST and TBiL concentrations in the two groups were lower than before treatment (P<0.05),and AST and TBiL concentrations in the observation group were lower than control group (P<0.05). After treatment,blood UA and BUN concentrations in the two groups were reduced (P<0.05),and the observation group was lower than that in the control group (P<0.05). The total effective rates in the observation group (97.83%) was higher than that of the control group (82.61%) (P<0.05). During treatment,there was 1 case of nausea,1 case of vomiting and 1 case of diarrhea in the observation group,and the incidence of adverse reactions was 6.52% (3/46),while 2 cases of nausea and 4.35% (2/46) were in the control group,there was no difference in the incidence of adverse reactions (correction value χ2=0.211,P=0.646). After treatment,the concentration of inflammatory factors in the two groups was lower than that before treatment (P<0.05),and the concentration of inflammatory factors in the observation group was lower than that in the control group (P<0.05). CONCLUSION: Ulinastatin in combination with metal biliary stent implantation improved liver and kidney functions,enhanced efficacy and safety,reduced inflammatory factors,and improved immune functions among pancreatic cancer patients with extrahepatic biliary obstruction.
