Abstract
• Liver resections were performed in 18 pigs with an inexpensive disposable plastic suction knife, an ultrasonic dissector, or a contact neodymium (Nd)–YAG laser. Technical aspects and intraoperative and postoperative data were compared. Intraoperative blood loss was less with the suction knife (112±28 mL) than with the ultrasonic dissector (149±45 mL) or Nd-YAG laser (174±25 mL). Operating time was similar in all groups. The number of ligatures used in the Nd-YAG laser group (12±1) was significantly less than in the ultrasonic dissector (27±2) or suction knife (32±2) groups. In the ultrasonic dissector group, there was an increase in postoperative white blood cell count and liver enzyme levels compared with the other two groups. Light microscopy revealed dilated bile ducts in the ultrasonic dissector resection group, which may reflect biliary stasis. There were no significant differences in mortality among the three experimental groups. Results indicated that the ultrasonic dissector and the contact laser method were not substantially better than an inexpensive, easily modified plastic suction catheter in performing a major nonanatomic liver resection in piglets.
