Objective To investigate the occurrence of chronic pain in patients with inguinal hernia after herniorrhaphy,analyze the risk factors of pain occurrence and establish a nomogram model.Methods Using the convenient sampling method,a total of 390 patients who underwent inguinal herniorrhaphy in Xinxiang Central Hospital from June 2021 to December 2022 were selected.They were divided into the chronic pain group and the non-chronic pain group based on whether postoperative chronic pain occurred.Logistic regression analysis was applied to identify risk factors for postoperative chronic pain,and the nomogram model was established using R4.2.3 software package and rms software package.Results Among 390 patients with inguinal hernia,a total of 73 patients experienced postoperative chronic pain,with the incidence of 18.72％.Logistic regression analysis showed that recurrent inguinal hernia surgery,hernia ring defect diameter less than or equal to 37.5px,incarceration,use of repair materials and postoperative incision infection were risk factors for chronic pain(P＜0.05).Based on the above factors,a risk prediction model was established.The area under the receiver operating characteristic curve for the test subject was 0.751(95％CI:0.612-0.753),the Hosmer-Lemeshow test results showed x2=5.572,P=0.473,and the correction curves were all close to the ideal curve.Conclusions Postoperative chronic pain is common in patients with inguinal hernia and there are many risk factors.The nomogram model established in this study can provide basis for formulating nursing strategies to some extent.
