Endoscopic biliary drainage efficiency on biliary decompression and drainage duration



Endoscopic biliary drainage efficiency on biliary decompression and drainage duration



Gastroenterological Endoscopy 29(11): 2429-2436



The effect of biliary decompression and drainage duration in endoscopic biliary drainage (EBD) were estimated on differences of methods or tube diameter (nasobiliary drainage: NB-D, duodeno-bilary drainage by 7.2 Fr tube: S-DB, by 10 Fr tube: L-DB or by combination of plural tubes: C-DB). The serum bilirubin values after biliary decompression in patients with obstructive jaundice are expected to decrease on an exponential curve. The values before and after each period should appear as linear regression on scattergram, and this regression coefficient means a reduction rate of jaundice. The values of total bilirubin at one week interval following EBD were examined in 46 cases (14 of bile duct cancer, 9 of gallbladder cancer, 16 of pancreatic cancer, 6 of cancer of papillar of Vater and one of gastric cancer). The correlation and regression analyses were made between the values before and after each period determining a regression coefficient as a "jaundice reduction index" of each group. Effect of reducing jaundice was estimated by analysis of covariance on each index. As a control, 20 cases of performed PTCD were also examined. Drainage duration of each drainage tube was estimated as the tube survival by Kaplan-Meier analysis and Generalized Wilcoxon analysis on 53 cases (17 of bile duct cancer, 10 of gallbladder cancer, 19 of pancreatic cancer, 6 of cancer of papilla of Vater and one of gastric cancer). "Jaundice reduction index" of each groups were NB-D=0.6152, S-DB=0.3596, L-DB=0.2297 and PTCD=0.6460. A statistically significant higher reduction rate was seen in L-DB and S-DB to PTCD, and also in L-DB to NB-D. On drainage duration, long term functioning of the endoprosthesis was not always shown in a large bore tube, and the result was poor in C-DB. As the tube survival in a short duration tends to be recognized in the same patient, we attempted a modified study by mean value in the same drainage in the same patient. A tube survival of C-DB turned to be long and we considered that the duration is influenced by patient's factor rather than drainage methods or tube diameter. In conclusion, internal drainage is more effective than external drainage on reduction of jaundice, and large bore endoprostheses may have higher reduction of jaundice. But in maintaining the patency, there are no remarkable differences between drainage methods or tube diameter.
