    Abstract:
    BACKGROUND/AIMS: Pancreatic body cancer often involves the common hepatic artery and/or the celiac axis, and is regarded as an unresectable disease. Hepatic blood flow must be monitored while performing distal pancreatectomy with en bloc celiac axis resection (DP-CAR) for managing the progression of pancreatic body cancer. We first confirmed a safe level of blood flow by monitoring hepatic venous oxygen saturation (ShvO2) to prevent hepatic ischemia caused by occlusion of the common hepatic artery. However, this method is technically difficult and a long period of time is required to insert the catheter. Thus, we monitored hepatic arterial flow by using a transonic flowmeter in the hepatic artery during operation. METHODOLOGY: Between April 1992 and January 2011, 14 patients underwent DP-CAR. In 6 of these 14 patients we measured ShvO2. In 2 of the 14 patients, a transonic flowmeter was used for determining the hepatic arterial flow during operation. RESULTS: There were no complications during this operation. Operation time when the blood flow was monitored using a transonic flowmeter was less than that when ShvO2 was measured. CONCLUSIONS: Monitoring the transonic flowmeter hepatic artery is a useful and quick method for real-time evaluation of hepatic circulation during operation.
