研究目的: |
本研究尝试建立一种成年男性患者腹腔镜下腹股沟疝修补术的疝囊处理决策模型,并通过前瞻性队列验证其临床有效性和安全性。具体目的包括: (1)整合患者临床特征(如年龄、BMI、疝囊大小、影像学评估等)、术中因素(如粘连程度、疝类型)等多维度变量,运用logistic回归开发预测模型,量化疝囊横断与完全剥离的适用概率,并评估模型的敏感性、特异性和AUC值 (2)在前瞻性队列中招募168例腹腔镜下腹股沟疝患者,根据模型推荐策略实施手术; (3)比较模型指导组与传统经验组的手术时间、术后并发症发生率(如血清肿、慢性疼痛),验证其临床有效性和安全性及在优化手术流程中的作用。 |

Objectives of Study: |
This study aimed to develop a decision-making model for hernia sac management in laparoscopic inguinal hernia repair in adult male patients, and to validate its clinical efficacy and safety through a prospective cohort study. The specific objectives were as follows: (1) to integrate multidimensional variables—including patient clinical characteristics (e.g., age, BMI, hernia sac size, imaging assessment) and intraoperative factors (e.g., degree of adhesion, hernia type)—to construct a predictive model using logistic regression that quantifies the probability of indication for hernia sac transection versus complete dissection. Model performance was evaluated based on sensitivity, specificity, and area under the receiver operating characteristic curve (AUC). (2) to enroll 168 patients undergoing laparoscopic inguinal hernia repair in a prospective cohort, with surgical strategy assigned according to the model’s recommendation; (3) to compare operative time, incidence of postoperative complications (e.g., seroma, chronic pain), and the model’s role in optimizing surgical workflow between the model-guided group and the traditional experience-based group, thereby validating its clinical efficacy and safety. |

随机方法(请说明由何人用什么方法产生随机序列): |
采用《医学统计学》(第3版)所附“随机数字表”进行分组。该临床试验预计入组168例研究对象,随机分为两组:研究组以及对照组,每组84例。具体分组方法为:首先将168例腹股沟疝患者从1开始编号到168;然后从随机数字表中的任一行任一列开始,如从第2行第5列开始,以此读取3位数作为一个随机数录入编号下面;再将全部选出的随机数从小到大进行编序号(随机数相同的按照先手顺序编号),记录在第三行;我们规定序号1-84为研究组,序号84-168为对照组。 |

Randomization Procedure (please state who generates the random number sequence and by what method): |
Group allocation was performed using the random number table provided in Medical Statistics (3rd edition). A total of 168 participants were enrolled in this clinical trial and randomly assigned to two groups: the study group and the control group, with 84 patients in each group. The specific randomization procedure was as follows: First, the 168 patients with inguinal hernia were sequentially numbered from 1 to 168. Beginning at a predetermined starting point in the random number table—for instance, row 2, column 5—three-digit random numbers were sequentially read and assigned to each corresponding patient number. All selected random numbers were then ranked in ascending order (with identical random numbers ordered by the sequence of their initial appearance) and recorded in the third row. Patients corresponding to ranks 1 through 84 were assigned to the study group, and those corresponding to ranks 85 through 168 were assigned to the control group. |
