Clinicopathological type of right lobular hepatolithiasis

Abstract

Objective To explore the distribution type of hepatolithiasis on right side and to provide foundation for surgical treatment. Methods One hundred and six patients suffering from hep-atolithiasis in right lobe underwent surgical treatment about distribution of stone during 1998-2005has been reported. Results The location of stones was the right hemihepatic type in 25 patients (23.8%), right hemihepatic associated with left lobe type in 33 (31.1%), right latter lobe type in 15(14.1%), right latter lobe with left lobe type in 9 (8.5%), right front lobe type in 4 (2.8%), right front lobe with left lobe type in 6 (5.7%), right latter inferior segment type in 3 (2.8%), right latter inferior with left lobe type in 6 (5.7%). The number of right hemihepatic type added with left lobe type was more than that of the right right latter lobe or right front lobe type added with left type (P 0.05). Conclusion The number of right hemihepatic type and right hemihepatic with left lobe type accounts for over 50% of right side hepatolithiasis about distribution type of stone. The right hemihepatic type and right latter lobe type added with left lobe type constitute the majority of distribution type of stone for right side hepatolithia-sis. The right hemihepatectomy and right latter lobectomy unite transcholedoscopy to draw stones from left side hepatic duct is the most common surgical operative pattern. This distribution type of stone has association with the anatomy of right hepatic duct and pathology of porta hepatic.
