Aim:
To compare the technical difficulty, safety, radiation exposure and success rates between right-sided and left-sided percutaneous transhepatic biliary drainage (RPTBD and LPTBD) in patients with malignant biliary obstruction (MBO).
Materials And Methods:
Fifty patients (28 males, 22 females; mean age 51.78 years) with MBO were randomized to undergo either RPTBD or LPTBD during the study period between June 2016 and May 2018. The procedure time, fluoroscopy time, radiation doses to the operators and patients, technical success, clinical success, complications and effect on quality of life were evaluated and compared between the two groups.
Results:
Twenty-five patients were included in each group. The technical success was 100% in both groups. There was no significant difference between RPTBD and LPTBD groups in terms of major complications [4% and 12%, respectively; p = 0.297] and minor complications [40% and 32%, respectively; p = 0.597]. Further, the average procedure time (37.80 ± 13.07 min vs 41.04 ± 14.94 min), fluoroscopy time (5.88 ± 4.2 min vs 5.97 ± 3.8 min), radiation doses to the operator (136.84 ± 106.67 μSv vs 130.40 ± 106.46 μSv) and to the patient (8.23 ± 5.80 Gycm2 vs 11.74 ± 11.28 Gycm2) were not significantly different between the groups. Clinical success was achieved in 21 patients (84%) of RPTBD group and 17 patients (68%) of LPTBD group with no significant difference (p = 0.416) between them.
Conclusion:
There was no significant difference between RPTBD and LPTBD with reference to the technique, safety, radiation dose, success rates and impact on quality of life suggesting no laterality advantage for biliary drainage in cases of MBO.
