The risk factors of bulging after hernia repair of ventral hernia

Objective To investigate the incidence and risk factors of bulging after herniorrhaphy for ventral hernia. Methods To analysis of the relationship between incidence and clinical case factors of 774 patients who underwent herniorrhaphy for ventral hernia from January 2008 to December 2017. Results After 3 to 18 months of follow-up, the postoperative hospital stay was (8.15±2.60) days, bulging was found in 58 cases (7.49%) of 774 patients postoperatively, which was correlated with body mass index (BMI), emergency cases, mesh position, surgical approach and defect closure. Conclusion The BMI, emergency cases, mesh position, surgical approach and defect closure were independent risk factors of bulging after herniorrhaphy for ventral hernia. In order to prevent and reduce the occurrence of bulging, we should strengthen the screening of preoperative cases, reduce the emergency operation rate, strictly control the weight of patients, select appropriate surgical methods and materials, close the defect facial and strengthen the management of incision after operation.
