Incidence and Associated Factors of Percutaneous Transhepatic Biliary Drainage Complications in Samutsakhon Hospital

Abstract

The objective of this study aims to determine the incidence and associated factors of percutaneous transhepatic biliary drainage (PTBD) complications in Samutsakhon Hospital. A retrospective descriptive study was conducted on 108 patients at Samutsakhon Hospital from January 15, 2018, to November 21, 2023. Patients’data, procedure-related data, and complications were collected. The incidence of PTBD complications was analyzed, and classified as non-infection-related and infection-related. The associated factors with complications were also evaluated using the Chi-square or Fischer exact test for categorical data and the independent t-test for continuous data. Statistically significant associated factors were then evaluated for multivariable analysis. The overall incidence of PTBD complications was about 31.48%. The most common complication was catheter dislodgement (44.1%). There were no major or lethal complications. The incidence of complications was 34.4% undergoing PTBD placement due to cholangiocarcinoma, and 31.1% with left sided PTBD. There was no statistically significant difference between the associated factors and PTBD complications. In conclusion, PTBD is generally a safe procedure but may cause some minor complications. Close observation during every step of the procedure is recommended.
