BACKGROUND/AIMS: Hyperamylasemia often occurs after hepatectomy, but the detailed mechanism of this phenomenon remains unclear. The aim of this study was to analyze factors that may be associated with the development of hyperamylasemia following hepatic resection. METHODOLOGY: The Pringle maneuver was performed in 12 patients (Pringle group), the hemihepatic vascular occlusion technique in 11 patients (Hemihepatic group). RESULTS: In the Pringle group, postoperative serum amylase levels were elevated significantly in comparison with the preoperative levels, but were not elevated in the hemihepatic group. CONCLUSIONS: It is suggested that portal congestion by portal triad interruption carries a potential risk of serum amylase elevation and pancreatitis after hepatectomy.
