Treatment of hepatolithiasis by hepatectomy and choledochoflberscopy

Objective To evaluate the effect of surgical therapy for hepatolithiasis by hepatectomy and choledochofiberscopy. Method We retrospectively analyzed hepatolithiasis patients in our hospital during the past 5 years, comparing the therapeutic effect of different surgical modality. Data were analyzed by chi-square test. Result A total of 469 patients underwent surgical treatment, 412(87.85%) cases were followed up for an average of 3 years and 6 months. The residual calculus rate was 5. 14% and 14. 81% (x2 =9.32,P0.01),the recurrence rate of calculus was 4.53% and 14.81%(x2=11.24, P 0.01),reoperation rate was 5. 14% and 16. 05% ( x2 = 11.48,P0.01) in hepatectomy group and non-hepatectomy group respectively; The residual calculus rate was 4.39% and 16. 13% (x=15. 17, P 0. 01) , the recurring rate of calculus was 3. 76% and 16. 13% ( x2 = 17. 98 , P 0. 01) , reoperation rate was 4. 08% and 18. 28% (X2=21. 52, P 0. 01 ) in patients undergoing choledochofiberscopy and without, respectively. Conclusion Use of choledochofiberscopy in combination with hepatectomy effectively improves therapeutic efficacy of surgical treatment for hepatolithiasis.
