摘要:
目的 探讨完全腹腔镜解剖性肝切除治疗左叶肝细胞癌的可行性及其疗效。 方法 自2006年6月至2009年12月间, 总结南昌大学第二附属医院肝胆外科收治21例确诊为左叶肝细胞癌且已行完全腹腔镜解剖性肝切除(laparoscopic anatomic hepateetomy, LAH)患者的围手术期的临床资料, 构成LAH研究组。在同一时间段, 以患者年龄、手术方式、肿瘤大小、肝硬化程度为配对条件, 在开腹解剖性肝切除治疗左叶肝细胞癌的病例库中进行1:1配对抽选, 共21例纳入LAH配对组。 结果 LAH研究组的手术时间为(156.67±32.15)min, 术中失血量为(157.14±40.51)mL, 两者均少于配对组(P=0.036, P < 0.001)。LAH研究组术后患者平均镇痛剂使用时间为(2.19±0.51)d, 平均首次进食时间为(2.24±0.44)d, 平均首次离床活动时间为(2.71±0.78)d, 平均住院时间为(7.86±1.24)d, 均优于配对组(P < 0.05)。两组并发症及死亡率差异没有统计学意义。术后中位随访期为21个月, LAH研究组的1、3年总体生存率分别为86%、62%, 配对组的1、3年总体生存率分别为90%、67%, Log-rank比较两组肝癌患者生存曲线差异无统计学意义。 结论 完全腹腔镜解剖性肝切除术治疗左叶肝细胞癌是安全可行, 具有一定的近期优势, 且术后总体生存率与开腹肝切除术相比无差别。 Abstract:Objective To evaluate the surgical results and mid-term survival of the cases undergoing total laparoscopic anatomic hepatectomy(LAH) for hepatocellular carcinoma(HCC) in the left lobe. Methods From June 2006 to December 2009, clinical records of 21 patients with HCC in the left lobe who underwent a total LAH operation were included in the LAH study group.During the same period, data on the matched-pair group of another 21 patients who underwent open anatomic hepatectomy were included in the LAH matched-pair group.The two groups were compared in terms of age, type of resection, tumor size, and severity of liver cirrhosis. Results The laparoscopic approach resulted in shorter duration of surgery(156.67±32.15 min, P=0.036) and less blood loss(157.14±40.51 mL, P=0.000) in the LAH study group, compared to the LAH matched-pair group.Statistically significant differences were found in the primary-porta-hepatic surgery duration between the LAH study group and the matched-pair group(P=0.001).The mean duration of the secondary-porta-hepatic surgery was similar for the two groups(P=0.061).In the LAH study group, the mean time for required analgesic medication(2.19±0.51 d vs.3.10±1.04 d), food intake(2.24±0.44 d vs.3.81±0.40 d), first ambulation time(2.71±0.78 d vs.3.52±0.93 d), and average stay (7.86±1.24 d vs.10.95±1.40 d) were all better than those of the matched-pair group(P < 0.05).No statistical significance in the perioperative morbidity and mortality rate were found between the two groups.After a median follow up of 21 months, the 1 and 3-year overall survival rates after liver excision for HCC were 86%and 62%in LAH study group, respectively, and those in the matched-pair group were 90%and 67%, respectively.No significant differences were observed in the survival curves in the present study. Conclusion The total LAH of HCC in the left lobe is feasible and safe for the selected patients and may result in good surgical results, with similar benefits in the overall survival. -
