T-tube choledochostomy is a useful surgical therapeutic method of biliary tract stones and has been considered as standard therapy for choledocholithiasis and hepatoliasis.
Especially t present, as the success rate of residual stones removal through T-tube fistula tract is higher due to the development of the interventional radiologic treatment, T-tube choledochostomy is being considered as the more important
method.
Therefore, the author had retrospecive analysis for benign biliary tract disease 303 cases were treated with choledochostomy from January 1989 to June 1993 at out institution in order to inspect the several problematic points in performing T-tube
choledochostomy.
@ES The results are summarized as follows:
@EN 1) The sex ratio of male to female was 1 to 1.56, and the peak incidence was noted in the 6th decade(15.7%).
2) 291 cases(96.1%) were biliary tract stone diseases, and 12 cases(3.9%) were non-calculous benign biliary tract diseases.
3) The most common etiologic disease was CBD stone(28.6%).
4) The patients who revealed normal serum bilirubin level(less that 1.5mg/dl) at admission were 160 cases(53.8%), 1.6~5mg/dl were 93 cases(31.6%).
5) Positive bile culture was obtained in 234 out of 289 cases. and E.coli was the most frequent etiologic organism(35.6%).
6) The number of patients containing residual stones at postoperative T-tube cholangiography was 112 cases(38.9%).
All of these patients were treated by Dormia basket stone removal, and complete stone removal rate was 62.5%, relative stone removal rate was 18.7%.
7) The postoperative complication rate was 17.1%, and wound infection was the most frequent complication (4.9).
8) Mortality rate was 1.3%(4 cases).
