Clinical application of endoscopic retrograde billiary drainage for obstruction of biliary tract caused by carcinoma of head of pancreas

Objective To evaluate the clinical efficacy of endoscopic retrograde billiary drainage （ERBD） for obstruction of biliary tract caused by carcinoma of head of pancreas. Methods Forty - six inpatients with biliary obstruction caused by carcinoma of head of pancreas were subjected to ERBD（ plastic or metal stent）and their clinical data were analyzed. Results Successful stent placement was performed in 39 cases of all. After ERBD,the serum total bilirubin of patients（ 104.67 ± 15.49）μmol/L was significantly decreased compared with that before ERBD （ 371.37 ±49.23 ） p, mol/L （ P 〈 0.01 ） and the liver function was improved before ERBD ： ALT（ 210.34 ± 27.25 ） U/L, AST （ 178.69 ± 19.79 ） U/L, r - GT （ 326.12 ± 25.96 ） U/L, ALP （ 489.77 ± 45.67 ） U/L）, after ERBD ： ALT （ 196.57 ± 19.29 ） U/L, AST （ 167.58 ± 18.97 ） U/L, r - GT （ 198.43 ± 20.86 ） U/L, ALP （ 298.56 ± 28.49 ） U/L ]. Occlusion of plastic stent occurred in 11 cases and the average time of occlusion were 162 days. Occlusion of metallic stent occurered in 4 cases and the average time of occlusion was 213 days. The survival rate for 6 months was 71.8% and 46.2% for one year. Conclusion ERBD may improve the conditions of patient with obstruction of biliary tract caused by carcinoma of head of pancreas. It is an alternative alleviative treatment for patients who cannot accept operation directly for carcinoma of head of pancreas or patients in terminal stage.
