Is There Any Indicator to Predict the Difficulty of PTBD?
Abstract
- PURPOSE
A retrospective study was performed to find any indicator to predict the difficulty of percutaneous
transhepatic biliary drainage(PTBD) before the procedure and to evaluate correlationship between the chronological change of fluoroscopic time and the operator's experience.
MATERIALS AND METHODS
The materials included the consecutive 138 cases of PTBD of 120 patients with
obstructive jaundice. Under the presumption that the difficulty of procedure would be reflected on fluoroscopic
time, the correlation between fluoroscopic time and eight factors(i. e. ;sex, age, disease, approach, degree of
IHD dilatation, total bilirubin, alkaline phosphatase, and operator) were analysed. Also chronological change of
fluoroscopic time in three operators, who performed more than 25 procedures, were evaluated.
RESULTS
Statistically significant factors were operator (P=0.000), sex (P:0.028), approach(P=0.048), and total
billrubin (P=0.021). Good correlation between the chronological change of fluoroscopic time and the operator's
experience was found.
CONCLUSION
The significant factors could be used as an indicator to predict the difficulty before PTBD procedure. The chronological change of fluoroscopic time could be used as an indirect estimate in the stabilization
of the operator fechnigue.
