Application of cavitron ultrasonic surgical aspirator in hepatic resection

Objective To explore the value of Cavitron Ultrasonic Surgical Aspirator (CUSA) in liver resection. Methods Medical records of patients underwent liver resection in Anshan Central Hospital from June 2012 to June 2015 were retrospectively analyzed. There were 37 cases in CUSA group and 25 cases in conventional group. The difference in indicators of baseline information, postoperative recovery and the incidence of complications were compared between the two groups. Results There were no significant differences in gender, age, blood test results, tumor size and other indicators between the two groups (P< 0.05). The average operating time in the group of CUSA was (169.6±36.2) min which was longer than (154.8±25.3) min in conventional group, while the difference was not statistically significant. However, the average blood loss and blood transfusion in CUSA group were significantly lower than those in conventional operation group(295.8±52.6) ml vs (427.5±71.3) ml, (240.6±39.2) ml vs (380.4±65.2) ml, P< 0.05, while the hemoglobin (Hb) and serum albumin (ALB) in CUSA group were significantly higher than those in conventional surgery group(118.5±8.6)g/L vs (108.3±6.9)g/L, (33.7±1.6)g/L vs (32.9±1.3)g/L, P< 0.05. The butalanine aminotransferase (ALT) and aspartate aminotransferase (AST) were (369.1±62.7) U/L and (437.6±59.3) U/L in CUSA group which were lower than those in conventional surgery group(452.7±58.2) U/L and (476.3±66.1) U/L at 3 days after operation (P< 0.05). Meanwhile, hemoglobin (Hb) and serum albumin (ALB) in CUSA group were significantly higher than those of the conventional surgery group(121.4±7.2) g/L vs (114.7±8.3) g/L, (35.2±0.9) g/L vs (34.7±0.7) g/L, P< 0.05, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were (127.3±26.5) U/L and (162.1±10.7) U/L in CUSA group which were lower than those in conventional surgery group(169.2±38.6) U/L and (185.7±32.6) U/L at 7 days after operation (P< 0.05). And the incidence of postoperative complications in CUSA group was 21.6% that was significantly lower than 48.0% of the conventional surgery group (P< 0.05). Conclusion CUSA can significantly reduce the incidence of postoperative complications, which has great value for liver cancer treatment in clinical application.
