New Fiberoptic Choledochoscopy-guided Percutaneous Transhepatic Choledochoscope Lithotomy Combined with Dual-frequency Laser Lithotripsy for the Treatment of Intractable Hepatolithiasis.

OBJECTIVE

To investigate the clinical effects of new fiberoptic cholangioscopy-guided percutaneous transhepatic choledochoscope lithotomy (PTCSL) combined with dual-frequency laser lithotripsy for the treatment of intractable hepatolithiasis.

METHODS

Eighty patients with intractable hepatolithiasis who received treatment in the Second Hospital Affiliated to Zhejiang University School of Medicine from December 2020 to December 2022 were grouped according to the surgical methods. Forty-two patients who received hepatectomy were divided into the control group, 38 patients who received new fiber-optic choledochoscope-guided PTCSL combined with dual-frequency laser lithotripsy were divided into the observation group, and the treatment results of the two groups were compared.

RESULTS

The operation time, postoperative pain duration, and hospital stay of the observation group were significantly shorter than those of the control group, and intraoperative bleeding was significantly lower than that of the control group, with statistically significant differences (P < .05). Seven days after surgery, the total bilirubin (TBIL), alanine aminotransferase (ALT), and albumin (ALB) levels in the observation group were significantly lower than those in the control group (P < .05). The stone residual rate of 7.89% in the observation group was significantly lower than that of 26.19% in the control group (χ2=4.625, P < .05). The difference in biliary bleeding rate between the two groups was not statistically significant (χ2=0.427, P > .05).

CONCLUSION

Overall results of new fiber-optic choledochoscope-guided PTCSL combined with dual-frequency laser lithotripsy for the treatment of intractable hepatolithiasis.
