Effect of cautery with irrigation forceps on the remnant liver after hepatectomy in rats.
Monopolar cautery with irrigation forceps (CIF) was devised for use in liver resection that does not require occlusion of inflow to the remnant liver. However, a high power output is required to divide the hepatic parenchyma which boils the irrigation water. This study was performed to investigate the effects of using CIF on the hepatic parenchyma. Histologic and biochemical examination was performed in rats which had undergone hepatectomy using the CIF, irrigating bipolar (IB), Pringle's maneuver with blunt dissection (group P), or a sham operation. A greater cautery distance was obtained with the CIF than the IB. There was no significant difference in the remnant liver function after the 1st postoperative day in any of the groups. CIF is an effective instrument for anatomic or nonanatomic hepatic resection.
