急性结石性胆囊炎腹腔镜胆囊切除中转开腹影响因素分析

Risk factors of conversion from laparoscopic cholecystectomy to laparotomy for acute calculous cholecystitis base on multivariate logistic regression analysis(a multicenter retrospective study)

目的:探讨急性结石性胆囊炎行腹腔镜胆囊切除术过程中转开腹的影响因素。方法:回顾性分析3191例急性结石性胆囊炎行腹腔镜胆囊切除术患者的临床资料,按术中是否中转开腹胆囊切除术分为中转组和非中转组,通过多元回归模式对患者性别、年龄、BMI、既往病史(糖尿病病史、高血压病史及既往腹部外科手术史)、术前实验室检查(WBC、PCT、CRP及INR)、术前胆囊B超特征(胆囊结石数量、胆囊壁厚度)及手术时间等因素进行统计学分析。结果:资料数据经多元logistic回归分析显示,BMI、糖尿病病史、术前白细胞计数、PCT、CRP、结石数量、胆囊壁厚度是影响急性结石性胆囊炎患者行腹腔镜胆囊切除中转开腹的因素(P<0.05);BMI(OR=1.784;95%CI:1.621~1.973;P<0.001)、糖尿病病史(OR=21.79;95%CI:13.49~34.90;P<0.001)、WBC(OR=1.330;95%CI:1.254~1.410;P<0.001)、PCT(OR=1.839;95%CI:1.631~2.079;P=0.004)、CRP(OR=2.025;95%CI:1.019~4.031;P=0.004)升高及胆囊壁增厚(OR=1.680;95%CI:1.520~1.859;P<0.001)为中转开腹的独立危险因素,而结石数量(OR=0.422;95%CI:0.273~0.643;P=0.0005)为中转开腹的保护因素。结论:急性结石性胆囊炎患者实施腹腔镜胆囊切除术时,对BMI超标、术前有糖尿病病史、术前WBC、PCT及CRP较高或B超显示胆囊壁增厚、结石单发的患者,应考虑术中中转开腹手术可能。

Objective: To investigate the risk factors of conversion from laparoscopic cholecystectomy transferring to laparotomy for acute calculous cholecystitis. Methods: Three thousand one hundred and ninety one patients with acute calculous cholecystitis who underwent laparoscopic cholecystectomy from Huadu District People’s Hospital of Guangzhou, Guangzhou First People’s Hospital, Guangzhou Red Cross Hospital, the First Affiliated Hospital/School of Clinical Medicine of Guangdong Pharmaceutical University, Guangzhou Nansha Central Hospital, Qingyuan Municipal People’s Hospital, People’s Hospital of Qianxi and the Second People’s Hospital of Huadu District of Guangzhou were analyzed retrospectively. Base on whether transferred to open cholecystectomy or not during the operation, all of the patients were divided into two groups: Conversion group and laparoscopic cholecystectomy group. And then the factors such as gender, age, BMI, previous medical history(diabetes, hypertension and previous abdominal surgery), preoperative laboratory examination(WBC, PCT, CRP and INR), preoperative gallbladder B-ultrasound characteristics(number of gallstones and thickness of gallbladder wall) were statistically analyzed by multiple logistic regression model. Results: Multivariate logistic regression analysis showed that BMI, history of diabetes, preoperative WBC, PCT, CRP, the number of stones and the thickness of gallbladder wall were the factors influencing the conversion from laparoscopic cholecystectomy transferring to laparotomy with acute calculous cholecystitis(P<0.05);High BMI(OR=1.784;95%CI: 1.621-1.973;P<0.001), diabetes history(OR=21.79;95%CI: 13.49-34.90;P<0.001), increase of WBC count(OR=1.330;95%CI: 1.254-1.410;P<0.001), PCT(OR=1.839;95%CI: 1.631-2.079;P=0.004) and CRP(OR=2.025;95%CI: 1.019-4.031;P=0.004) and thickness of gallbladder wall(OR=1.680;95%CI: 1.520-1.859;P<0.001) were the independent risk factors for conversion to laparotomy, while the number of calculi(OR=0.422;95%CI: 0.273-0.643;P=0.0005) was the protective factor for conversion to laparotomy. Conclusion: When laparoscopic cholecystectomy is performed in patients with acute calculous cholecystitis, the possibility of conversion to laparotomy should be considered for those patients with High BMI, preoperative diabetes history, preoperative high white blood cell count, high PCT and CRP, or gallbladder wall thickening and solitary stones shown by B-ultrasound.
