Favorable outcomes of hilar duct oriented hepatic resection for high grade Tsunoda type hepatolithiasis

Figure 1 Schematic drawing of VHE procedure during left lobectomy. A: Hepatotomy commences vertically from the Cantlie’s line to the direction of the hilar bile duct (thick arrow); B: after reaching the hilum, the hepatotomy is continued along the pre-caudate plane (angled thick arrow); C: the ventral portion of the hilar hepatic duct is opened along its direction; D: after completion of the necessary ductal procedure.
