目的
2
探究CT影像学特征对复杂胆囊结石患者腹腔镜逆行胆囊切除术(LRC)中转开腹的预测价值。
方法
2
选取我院行LRC的1 500例复杂胆囊结石患者,按是否中转开腹分为中转开腹组(
n
=90)与非中转开腹组(
n
=1 410)。收集患者临床基线资料、术前血液学指标及手术相关指标。采用CT评估结石特征(数量、最大径、位置)、胆囊形态(是否增大、胆囊壁厚度)、局部粘连与积液(胆囊三角区粘连、胆囊周围积液)及解剖变异(胆管、血管变异)。通过多因素
Logistic
回归分析筛选LRC中转开腹的独立危险因素,构建临床因素模型及临床联合CT影像学特征模型,绘制受试者工作特征(
ROC
)曲线评估模型预测效能。
结果
2
Logistic
回归分析结果表明,胆囊颈结石、结石数量多发、胆囊增大、胆囊壁厚度≥5 mm、胆囊三角区及胆囊壁粘连、胆囊周围存在积液、胆囊管/胆总管解剖变异是LRC中转开腹的独立危险因素(
P
<
0.05)。

检验显示临床因素联合CT影像学特征模型拟合良好(

ROC
曲线验证提示临床因素联合CT影像学特征模型的曲线下面积(

)为0.896(95%
CI

P
<

结论
2
CT影像在预测复杂胆囊结石患者LRC中转开腹方面具有重要价值,有助于术前评估和手术决策指导。
Objective
2
To investigate the predictive value of CT imaging features for conversion to open laparotomy during laparoscopic retrograde cholecystectomy (LRC) in patients with complex gallstones.
Methods
2
A total of 1 500 patients with complex gallstones who underwent LRC in our hospital were enrolled and divided into the conversion-to-open group (
n
=90) and the non-conversion group (
n
=1 410) according to the operative methods. Clinical baseline data, preoperative hematological indicators and surgery-related parameters were collected. CT was used to evaluate stone characteristics (number, maximum diameter, location), gallbladder morphology (gallbladder enlargement, gallbladder wall thickness), local adhesion and effusion (adhesion in gallbladder triangle, pericholecystic effusion
), and anatomical variations (bile duct and vascular variations). Independent risk factors for conversion to open laparotomy during LRC were screened by multivariate
Logistic
regression analysis. A clinical factor model and a clinical factor combined with CT imaging feature model were constructed, and
receiver operating characteristic
(
ROC
) curve was drawn to evaluate the predictive efficacy of the models.
Results
2
Logistic
regression analysis showed that gallbladder neck stones, multiple stones, gallbladder enlargement, gallbladder wall thickness ≥5 mm, adhesion in gallbladder triangle and gallbladder wall, pericholecystic effusion, and anatomical variation of cystic duct/common bile duct were the independent risk factors for conversion to open laparotomy during LRC (
P
<
0.05). The
Hosmer
-
Lemeshow
test indicated that the clinical factor combined with CT imaging feature model was well fitted (
P
=0.42), with a determination coefficient
R
² of 0.56.
ROC
curve verification showed that the
area under the curve
(
AUC
) of the clinical factor combined with CT imaging feature model was 0.896 (95%
CI
: 0.847 to 0.962), which was significantly better than that of the clinical factor model (
P
<
0.05).
Conclusion
2
CT imaging has important value in predicting conversion to open laparotomy during LRC in patients with complex gallstones, and is helpful for preoperative evaluation and surgical decision-making.
