目的

基于倾向性评分匹配(PSM)分析腹腔镜肝门部胆管癌根治术的安全性。

方法

回顾性分析2016年1月至2021年12月在重庆医科大学附属第一医院行肝门部胆管癌根治术的48例患者临床资料。其中男27例,女21例;年龄37~76岁,中位年龄67岁。患者均签署知情同意书,符合医学伦理学规定。根据手术方式将其分为腹腔镜组(10例)和开腹组(38例)。采用倾向性评分匹配(PSM)对腹腔镜组与开腹组进行1∶1匹配,匹配后两组各10例。比较两组患者围手术期情况。两组手术时间比较采用t检验;术中出血量、术后1 d视觉模拟评分(VAS)、术后住院时间比较采用秩和检验;术中输血率、严重并发症发生率比较采用Fisher确切概率法。

结果

PSM后腹腔镜组和开腹组平均手术时间分别为(429±100)、(364±97)min,差异无统计学意义(t=1.484,P>0.05)。两组术中出血量中位数分别为300(325)、250(225)ml,术后1 d VAS评分分别为2.5(2.0)、3.0(1.0)分,术后住院时间分别为16(6)、18(8)d,差异无统计学意义(Z=0.733,-0.457,-0.682;P>0.05)。两组术中输血分别为3、1例,术后胆漏分别为0、1例,差异亦无统计学意义(P=0.276,0.371)。

结论

在腹腔镜技术成熟及手术配合熟练的团队,腹腔镜应用于肝门部胆管癌根治术中是安全、可行的,与传统开腹手术围手术期安全性无明显差异。

Objective

To evaluate the safety of laparoscopic radical resection of hilar cholangiocarcinoma based on propensity score matching (PSM).

Methods

Clinical data of 48 patients who underwent radical resection of hilar cholangiocarcinoma in the First Affiliated Hospital of Chongqing Medical University from January, 2016 to December, 2021 were retrospectively analyzed. Among them, 27 patients were male and 21 female, aged from 37 to 76 years, with a median age of 67 years. The informed consents of all patients were obtained and the local ethical committee approval was received. According to the surgical pattern, all patients were divided into the laparoscopic group (n=10) and open surgery group (n=38). After 1∶1 PSM, 10 patients were assigned into the laparoscopic group and 10 in the open surgery group. Perioperative conditions were compared between two groups. The operation time between two groups was compared by t test. Intraoperative blood loss, visual analogue scale (VAS) score at postoperative 1 d, and the length of postoperative hospital stay were compared by sum-rank test. Intraoperative blood transfusion rate and the incidence of severe complications were compared by Fisher's exact probability test.

Results

After PSM, the average operation time in the laparoscopic and open surgery groups was (429±100) min and (364±97) min, and the difference was not statistically significant (t=1.484, P>0.05). In the laparoscopic and open surgery groups, the median intraoperative blood loss was 300(325) ml and 250(225) ml, the VAS scores at postoperative1 d were 2.5(2.0) and 3.0(1.0), and the length of postoperative hospital stay was 16(6) d and 18(8) d, and no significant difference was observed (Z=0.733, -0.457, -0.682; P>0.05). In the laparoscopic group, 3 patients received intraoperative blood transfusion and 1 in the open surgery group. No patient developed postoperative bile leakage in the laparoscopic group, and 1 case in the open surgery group, and no significant difference was observed (P=0.276, 0.371).

Conclusions

It is safe and feasible to perform laparoscopic radical resection of hilar cholangiocarcinoma for surgical teams with mature laparoscopic technique and intimate surgical cooperation. There is no significant difference in perioperative safety between laparoscopic and open surgeries.
