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.%目的 探讨超声吸引手术刀(cavitron ultrasonic surgical aspirator,CUSA)在肝肿瘤切除手术中的应用价值.方法 回顾性分析鞍山市中心医院普外一科2012年6月-2015年6月应用CUSA技术实施的肝肿瘤切除37例(CUSA组)及同期实施的常规肝肿瘤切除术25例(常规组)资料,比较两组患者手术情况、术后恢复及并发症发生率的差异.结果 两组性别、年龄、入院血液检验指标、肿瘤直径等差异无统计学意义(P＞ 0.05);CUSA组平均手术时间为(169.6±36.2) min,长于常规组的(154.8±25.3) min,但差异无统计学意义;CUSA组的术中平均出血量及平均输血量分别为(295.8±52.6) ml、(240.6±39.2),均低于常规手术组的(427.5±71.3)、(380.4±65.2)(P＜0.05).CUSA组患者术后第3天的Hb和ALB分别为(118.5±8.6) g/L、(33.7±1.6) g/L,均高于对照组的(108.3±6.9) g/L、(32.9±1.3) g/L(P＜0.05);ALT、AST分别为(369.1±62.7)U/L、(437.6±59.3) U/L,均低于对照组的(452.7±58.2) U/L、(476.3±66.1) U/L(P＜0.05).CUSA组患者术后第7天的Hb和ALB分别为(121.4±7.2) g/L、(35.2±0.9) g/L,均高于对照组的(114.7±8.3) g/L、(34.7±0.7)g/L(P＜0.05);ALT、AST分别为(127.3±26.5) U/L、(162.1±10.7) U/L,均低于对照组的(169.2±38.6)U/L、(185.7±32.6) U/L(P＜0.05);此外,CUSA组患者术后并发症发生率为21.6％,明显低于常规手术组的48.0％(P＜0.05).结论 CUSA大大降低了患者术后并发症的发生率,具有较好的临床应用价值.
