摘要:
目的 探讨3种腹腔镜肝切除术难度评分系统(DSS)评估手术难度和预测短期术后结果的准确性。 方法 选取2015年6月—2020年5月于兰州大学第一医院行腹腔镜肝切除术的患者142例,收集患者术前、术中和术后临床资料。根据术前资料,用DSS-B评分、Hasegawa评分和Halls评分3种DSS对每个患者手术的难度进行评分并分为低、中、高难度3组,比较各组间术中资料的差异,以验证3种DSS的准确性;用术后资料评估DSS对短期术后结果的预测能力。正态分布的计量资料多组间比较采用方差分析,进一步两两比较采用LSD-t检验;非正态分布的计量资料多组间比较及进一步两两比较均采用Kruskal-Wallis H检验。计数资料组间比较采用χ2检验或Fisher精确概率法,两两比较的P值用Bonferroni法校正。通过绘制受试者工作特征曲线(ROC曲线)并计算曲线下面积(AUC),评价DSS对术后并发症的预测效能。 结果 142例患者中,DSS-B评分低、中、高难度组分别有37、56、49例;Hasegawa评分低、中、高难度组分别有70、47、25例;Halls评分低、中、高难度组分别有46、62、34例。DSS-B评分、Hasegawa评分和Halls评分在低、中、高难度组之间手术时间、术中出血量、肝门阻断率均随难度评分的升高而增高(P值均<0.001);术中输血率方面,DSS-B评分仅在中难度与高难度组间差异有统计学意义(P<0.017),Halls评分在低难度与高难度组间差异有统计学意义(P<0.017),而Hasegawa评分低难度与中难度、高难度组比较,差异均有统计学意义(P值均<0.017);中转开腹率方面,DSS-B评分中难度与高难度组间差异有统计学意义(P<0.017),Hasegawa评分、Halls评分可区分低难度与高难度组间差异(P值均<0.017)。术后住院时间方面DSS-B评分和Halls评分均只能区分低难度与高难度组间差异(P值均<0.05),Hasegawa评分则可区分低难度与中难度、高难度的组间差异(P值均<0.05);术后并发症发生率方面仅Hasegawa评分可有效区分高难度与低难度、中难度的组间差异(P值均<0.017)。DSS-B评分、Halls评分和Hasegawa评分预测术后并发症的AUC分别为0.636(95%CI:0.515~0.758)、0.557(95%CI:0.442~0.673)、0.760(95%CI:0.654~0.866),其中Hasegawa评分的预测效能最大。 结论 DSS-B评分和Hasegawa评分可较好地评估腹腔镜肝切除术难度,Hasegawa评分在预测短期术后结果方面具有优势。 Abstract:Objective To investigate the accuracy of three laparoscopic liver resection (LLR) difficulty score systems (DSSs) in evaluating surgical difficulty and predicting short-term postoperative outcome. Methods The retrospective cohort study was conducted for 142 patients who underwent LLR in The First Hospital of Lanzhou University from June 2015 to May 2020, and their preoperative, intraoperative, and postoperative clinical data were collected. According to preoperative clinical data, DSS-B score, Hasegawa score, and Halls score were used to determine the difficulty score of surgery for each patient, and then the patients were divided into low, medium, and high difficulty groups. Intraoperative data were compared between the three groups to verify the accuracy of the three DSSs, and postoperative clinical data were used to evaluate the ability of DSSs to predict short-term postoperative outcome. An analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple or two groups. The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups, and the Bonferroni method was used for correction of P values between two groups. The receiver operating characteristic (ROC) curve was plotted and the area under the ROC curve (AUC) was calculated to evaluate the efficiency of each DSS in predicting postoperative complications. Results Among the 142 patients, there were 37 patients in the low difficulty group, 56 in the medium difficulty group, and 49 in the high difficulty group based on DSS-B score; there were 70 patients in the low difficulty group, 47 in the medium difficulty group, and 25 in the high difficulty group based on Hasegawa score; there were 46 patients in the low difficulty group, 62 in the medium difficulty group, and 34 in the high difficulty group based on Halls score. For the low, medium, and high difficulty groups based on DSS-B score, Hasegawa score, or Halls score, time of operation, intraoperative blood loss, and rate of hepatic portal occlusion increased with the increase in difficulty score (all P < 0.001); there was a significant difference in intraoperative blood transfusion rate between the medium and high difficulty groups based on DSS-B score (P < 0.017), between the low and high difficulty groups based on Halls score (P < 0.017), and between the low, medium, and high difficulty groups based on Hasegawa score (P < 0.017). There was a significant difference in the rate of conversion to laparotomy between the medium and high difficulty groups based on DSS-B score (P < 0.017), and Hasegawa score and Halls score identified the difference between the low and high difficulty groups (P < 0.017). For the length of postoperative hospital stay, DSS-B score and Halls score only identified the difference between the low and high difficulty groups (P < 0.05), while Hasegawa score identified the difference between the low difficulty group and the medium/high difficulty groups (P < 0.05); for the incidence rate of postoperative complications, only Hasegawa score effectively identified the difference between the high difficulty group and the low/medium difficulty groups (P < 0.017). DSS-B score, Halls score, and Hasegawa score had an AUC of 0.636 (95% confidence interval [CI]: 0.515-0.758), 0.557 (95% CI: 0.442-0.673), and 0.760 (95% CI: 0.654-0.866), respectively, in predicting postoperative complications, among which Hasegawa score had the highest predictive efficiency. Conclusion DSS-B score and Hasegawa score can better assess the difficulty of LLR, and Hasegawa score has an advantage in predicting short-term postoperative outcome. -
