探讨腹腔镜下经腹腹膜前疝修补术（TAPP）后慢性疼痛的危险因素，并建立预测TAPP术后慢性疼痛的风险列线图模型。

选取2015年2月2020年12月于蚌埠市第三人民医院进行诊治的179例行TAPP腹股沟疝患者作为研究对象，分析所选患者的临床资料，根据是否发生慢性疼痛将所选患者分为慢性疼痛组（30例）和正常组（149例），采用Logistic回归分析筛选TAPP后慢性疼痛的危险因素，并建立TAPP后慢性疼痛的风险列线图模型。

所选179例患者中，有30例（16.76%）患者发生了慢性疼痛。Logistic回归分析结果显示，年龄<40岁、机械性固定补片、术后切口感染、再次手术及手术时间≥100 min为TAPP后慢性疼痛的独立危险因素（P<0.05）。基于年龄、机械性固定补片、术后切口感染、手术次数及手术时间TAPP后慢性疼痛的独立危险因素，建立预测TAPP后慢性疼痛的风险列线图模型，C-index指数为0.771（95% CI：0.732~0.811），预测值和实测值基本一致，列线图受试者工作特征曲线下面积为0.751。

年龄<40岁、机械性固定补片、术后切口感染、再次手术及手术时间≥100 min为TAPP后慢性疼痛的独立危险因素，基于以上五项独立危险因素所建立的列线图有助于预测TAPP后慢性疼痛的发生风险。

To investigate the risk factors of chronic pain after laparoscopic preperitoneal hernia repair, and to establish a nomogram model for predicting chronic pain after laparoscopic preperitoneal hernia repair.

Selected 179 patients who were admitted to our hospital between February 2015 and December 2020 for diagnosis and treatment underwent laparoscopic transabdominal preperitoneal hernia repair as the research object, analyzed the clinical data of the selected patients, and selected them according to whether chronic pain occurred. Patients were divided into chronic pain group (n=30) and normal group (n=149). Logistic regression analysis was used to screen the risk factors of chronic pain after laparoscopic transabdominal preperitoneal hernia repair, and establish laparoscopic transabdominal peritoneum a nomogram model of the risk of chronic pain after anterior hernia repair.

Among the selected 149 patients, 30 (16.76%) patients had chronic pain. Logistic regression analysis showed that age<40, mechanical fixation patch, postoperative wound infection, reoperation and operation time ≥100 min were independent risk factors for chronic pain after laparoscopic transabdominal preperitoneal hernia repair (P<0.05). Based on the independent risk factors of chronic pain after laparoscopic transabdominal preperitoneal hernia repair, such as age, mechanical fixation patch, postoperative wound infection, number of operations, and operation time, a nomogram model for predicting chronic pain after TAPP were established, with a C-index index of 0.771 (95% CI: 0.732-0.811), the predicted value is basically the same as the measured value, and the area under the ROC curve (AUC) of the nomogram is 0.751.

Age <40 years, mechanical fixation patch, postoperative incision infection, reoperation and operation time ≥100 minutes are independent risk factors for chronic pain after laparoscopic transabdominal preperitoneal hernia repair, based on the above five independent risk factors. The established nomogram helps predict the risk of chronic pain after laparoscopic preperitoneal hernia repair.
