Comparative study of the effect of U100 laser and pneumatic ballistic combined with percutaneous transhepatic cholangioscopic lithotomy in the treatment of intra-and extrahepatic bile duct stones and its effect on liver function

Abstract

Objectives: To compare the efficiency of U100 laser and pneumatic ballistics combined with percutaneous transhepatic cholangioscopic lithotripsy (PTCSL) in the treatment of intra-and extrahepatic bile duct stones and their effects on liver function. Methods: Medical records of 97 patients with intra-and extrahepatic bile duct stones treated in our hospital from May 2020 to May 2021 were selected for retrospective analysis. Of them, forty-three patients received pneumatic ballistic lithotripsy combined with PTCSL (Group-I), and 54 patients received U100 laser lithotripsy combined with PTCSL (Group-II). The therapeutic effects of the treatment in two groups and its effect on liver function were compared and analyzed. Results: There was no significant difference in the operation time and intraoperative bleeding (P>0.05) between the two groups. The postoperative pain duration and hospital stay of patients treated with U100 laser lithotripsy combined with PTCSL (Group-II) were shorter than those treated with pneumatic ballistic lithotripsy combined with PTCSL (Group-I), P<0.05. The biliary bleeding rate of patients in Group-II was lower (3.70%) than those in Group-I (16.27%, P<0.05), and the stone residue rate of patients in Group-II was also lower (1.85%) than those in Group-I (11.63%, P<0.05). The levels of total bilirubin (TBIL), alanine aminotransferase (ALT) and albumin (ALB) in Group-II patients were higher than in patients in Group-I.(P<0.05). Conclusion: Compared with pneumatic ballistics, U100 laser lithotripsy combined with PTCSL in the treatment of intra and extrahepatic bile duct stones has the advantages of less postoperative pain, shorter hospital stay, less biliary bleeding and stone residue, and less damage to liver function. doi: https://doi.org/10.12669/pjms.38.6.5903 How to cite this:Yin Z, Shen B.
