Hepatic resection for hepatolithiasis and long-term results

Abstract

Background: Hepatic resection is an established procedure for treating patients with hepatolithiasis. The long-term results after hepatic resection for hepatolithiasis were appraised.

Study design: Of 127 patients with hepatolithiasis seen between 1973 and 1993, 43 patients underwent hepatic resection, and constituted the basis of this study.

Results: There was one operative death (operative mortality rate of 2.3 percent) and three deaths as a result of concomitantly associated cholangiocellular carcinoma. Of the remaining 39 patients, the complete stone clearance rate was 67 percent with operation alone, but reached 87 percent when cholangioscopy was used. Operative morbidity was recorded in five patients (12 percent), but they recovered with conservative therapy. Stones recurred in 15 percent of patients after a mean follow-up period of four years (range of three to six years). Eleven (28 percent) of 39 patients died after hepatectomy as a result of related diseases after a mean follow-up of 6.2 years. These 11 patients had associated biliary drainage procedures. They experienced a higher mortality rate (p < 0.05) than patients who did not have biliary drainage.

Conclusions: We conclude that hepatic resection is adequate treatment for hepatolithiasis. The patients having additional biliary drainage procedures had a higher mortality, but one cannot reach conclusions about the negative effect of the drainage procedures because the drainage procedures were done in a selected and not a randomized manner.
