分析腹股沟疝术后感染的原因，探讨临床治疗方法。

收集2018年1月至2022年1月，南京医科大学附属南京医院普外科收治的13例腹股沟疝术后感染患者的临床资料进行回顾分析。分析患者的感染情况，腹股沟疝手术采用的术式、补片、发病时间、感染的治疗方法、住院时间及伤口愈合情况。

13例患者中腹股沟疝术后浅部感染10例，深部感染3例。10例浅部感染患者腹股沟疝手术方式为，Lichtenstein术7例，网塞技术3例。均采用聚丙烯补片。发病时间（7.10±1.10）d。深部感染3例，腹股沟疝手术术式分别为，Lichtenstein术2例，TEP 1例。2例采用聚丙烯补片，1例为生物补片。发病时间（42.33±34.99）d。10例浅部感染患者经清创、闭式引流、二期缝合，伤口全部愈合，补片未取。3例深部感染患者经抗感染，取出补片后，临床治愈。13例患者术后随访4~6个月，未见复发。

腹股沟疝术后感染多数为浅部感染，应早期积极处理，可应用闭式负压引流，加速伤口愈合，减少住院时间。深部感染伴有补片感染相对复杂，经腹腔镜探查、适时取出补片等处理，获得满意疗效。

To investigate the etiology and clinical treatment of postoperative inguinal hernia infection.

Clinical data of 13 patients with postoperative inguinal hernia infection admitted to the Department of General Surgery, Nanjing Hospital Affiliated to Nanjing Medical University from January 2018 to January 2022 were retrospectively analyzed. The patient's infection situation, the surgical method used for inguinal hernia surgery, the type of patch, the onset time, the treatment method for infection, hospital stay, and wound healing status were analyzed.

Among the 13 patients with inguinal hernia, there were 10 cases of superficial infection after the operation and 3 cases of deep infection. The surgical methods of inguinal hernia in 10 patients with superficial infection were Lichtenstein in 7 cases and mesh plug technique in 3 cases. The meshes used all polypropylene mesh. The onset time was (7.10±1.10) days. There were 3 cases of deep infection, 2 cases of Lichtenstein operation and 1 case of TEP. The meshes used polypropylene mesh (2 cases) and biological mesh(1 case). The onset time was (42.33±34.99) d. After debridement, closed drainage and secondary suture after dressing change, the wounds of 10 patients with superficial infection were all healed without mesh removal. Three patients with deep infections were healed after the active operation to remove mesh. The 13 patients were followed up for 4-6 months, and no recurrence was observed.

Most postoperative inguinal hernia infections are superficial infections that should be treated early, especially with the use of closed negative pressure devices, which can accelerate wound healing and reduce hospital stay. The deep infection with mesh infection is relatively complicated, and the correct treatment, such as intraoperative laparoscopic exploration and timely mesh removal can obtain satisfactory clinical efficacy.
