探讨负压封闭引流与根治性感染网片切除在腹壁疝无张力修补术后感染中的应用。

选取2013年10月至2018年10月，川北医学院附属医院收治的腹壁疝无张力修补术后发生补片感染63例患者的临床资料，根据患者当时所给予的治疗方案不同，分为根治性感染网片切除组与负压引流组。根治性感染网片切除组采取常规感染补片切除术与腹壁重建术，负压引流组通过负压引流技术（VSD）材料进行负压封闭引流。

负压引流组未发现复发患者，根治性感染网片切除组患者中出现6例复发，差异有统计学意义（χ²=4.103，P=0.043）。根治性感染网片切除组治愈32例，无效1例；负压引流组治愈28例，无效2例。2组患者治愈情况比较，差异无统计学意义（96.97% vs 93.33%，χ²=0.007，P=0.933）。

与根治性感染网片切除术相比，VSD术具有同样的治疗有效性以及更低的治疗后复发率，同时手术操作简单，降低患者的手术风险以及手术费用，值得临床推广应用。

To compare the treatment of infection following ventral henria tension-free repair by vacuum sealing drainage (VSD) and radical infection mesh resection.

A total of 63 patients with mesh infection after ventral hernia tension-free repair in affiliated hospital of North Sichuan Medical College from October 2013 to October 2018 were selected. According to the treatment plan given at that time, the patients were divided into radical infection mesh resection group and VSD group. In the radical infection mesh resection group, conventional infection mesh resection and abdominal wall reconstruction were performed, while in the VSD group, VSD materials were used for vacuum sealing drainage.

No recurrence was found in the VSD group, and 6 recurrences occurred in the radical infection mesh resection group. The difference was statistically significant (χ²=4.103, P=0.043). In the radical infection mesh resection group, 32 cases were cured and 1 case was ineffective. While in the VSD group, 28 cases were cured and 2 cases were ineffective. There was no significant difference in the cure rate of the two groups of patients (96.97% vs 93.33%, χ²=0.007, P=0.933).

Compared with radical infection mesh resection, VSD has the same treatment effectiveness and lower recurrence rate after treatment. At the same time, the operation is simple and reduces the operation risk and operation cost of patients. It is worthy of clinical application.
