Abstract:
Objective:To study minimally invasive treatment using percutaneous transhepatic choledochoscopic lithotripsy (PTCSL) to treat complicated hepatolithiasis.Methods:Patients with complicated hepatolithiasis who were treated at the Second Affiliated Hospital of Kunming Medical University from July 2017 to September 2021, were included into this study. There were 48 patients treated with PTCSL (the PTCSL group) and 150 patients treated with conventional open hepatectomy (the OH group). Propensity score matching (PSM) was used to match 40 patients in the PTCSL group with 40 patients in the OH group. There were 11 males and 29 females, aged 32 to 85 (59.3±12.7) years in the PTCSL group and 15 males and 25 females, aged 20 to 74 (55.4±10.9) years in the OH group. Theoperation time, intraoperative blood loss, hospitalization time, hospitalization cost, incidences of major complications (including pleural effusion, biliary bleeding), residual stone rates and recurrence rates were analyzed.Results:Baseline data were comparable between groups after PSM. For the PTCSL group, the operation time was (135.8±42.6) minutes, intraoperative bleeding volume 32.5(20.0, 50.0) ml, hospitalization time 13.5(11.0, 18.0) days, and hospitalization expense 3.4(2.9, 5.0) wanyuan compared with the corresponding figures in the OH group with operation time (350.7±113.8) minutes, intraoperative bleeding volume 475.0(200.0, 900.0) ml, hospitalization time 24.0(17.3, 28.8) days, and hospitalization expense 6.6(5.0, 8.9) wanyuan. The differences between the two groups were statistically significant (all P<0.05). The overall complication rate was 2.5%(1/40) in the PTCSL group and 22.5%(9/40) in the OH group (χ 2=7.31, P=0.007). The residual stone rate of 20.0%(8/40), stone recurrence rate of 17.5%(7/40), compared with the OH group with the stone residual rate of 27.5%(11/40), stone recurrence rate of 12.5%(5/40). There was no significant difference between the two groups in both the stone residual rates and stone recurrence rates (both P>0.05). Conclusion:In treatment of complex hepatolithiasis, the stone residual rate after repeated PTCSL was comparable to traditional open hepatectomy. PTCSL had the advantages of shorter operation time, less bleeding, lower hospitalization time, lower complication rate and lower hospitalization cost. PTCSL is worthy of wider application and popularization.
