Abstract: Objective The aim of this clinical observation was to investigate the efficacy and safety of CT-guided percutaneous transhepatic choledochoscopic lithoteipsy (PTCSL) and dual-frequency laser lithotripsy (DFLL) combination in the treatment of patients with recurrent hepatolithiasis. Methods A total of 60 patients with recurrent hepatolithiasis were admitted to our hospital between September 2017 and February 2020, and 31 patients in group A received CT-guided PTCSL and DFLL and 29 patients in group B underwent open choledochofiberscope and DFLL. Serum cortisol (COR) and epinephrine (EP) were detected. Results The operation time, exhaust time, first defecation time and postoperative hospitalization stay in group A were(89.7±10.1)min, (30.3±3.6)h, (2.3±0.3)d and (6.9±1.1)d, all significantly shorter than [(101.9±12.2)min, (34.7±4.1)h, (2.7±0.4)d and (11.8±1.6)d, respectively, P<0.05], while blood loss was (40.2±8.8)ml, much less than [(97.4±10.6)ml, P<0.05] in group B; at the end of seven days after operation, the white blood cell counts, neutrophil percentage, serum COR and EP levels were (9.7±1.0)×109/L, (67.8±5.9)%, (310.1±30.7)mmol/L and (210.7±22.8)pg/mL, significantly lower than [(11.8±1.3)×109/L, (76.4±7.1)%, (385.5±34.4)mmol/L and (247.3±23.1), respectively, P<0.05] in group B; serum ALT, AST, ALP and bilirubin level were (39.7±3.7)U/L, (39.9±4.1)U/L, (80.1±8.5) and (19.4±1.8)μmol/L, significantly lower than [(45.6±5.1)U/L, (45.5±5.1)U/L, (85.9±6.8) and (23.0±3.4), respectively, P<0.05] in group B; the incidence of postoperative complications was 9.7%, significantly lower than 41.4% (P<0.05) and the stone residual rate was 6.5%, significantly lower than 31.0% in group B(P<0.05). Conclusion CT-guided (PTCSL) and DFLL combination could reduce surgical damage, accelerate postoperative recovery of gastrointestinal functions with low stone residual rate, which might be related to less oxidative stress and inflammatory reaction.
