腹壁切口疝168例病因分析

目的探讨腹壁切口疝的发病原因。方法从切口类型大小、缝合技术、材料、切口感染、腹内压增高、年龄、体重、营养和发生时间等方面对168例切口疝进行回顾性分析。结果168例切口疝患者中51～70岁者135例（80．4％），发生于腹壁纵行切口者145例（86．O％），发生于术后2-6个月者84例（50．0％）．其他如切口过大、缝合技术欠佳、切口感染、腹内压增高、超重、低蛋白血症和糖尿病等因素的存在也易诱发切口疝。结论横向切口，严格操作，严密止血，正确使用抗生素，预防切口感染，防止腹内压升高，营养充足，减少体重和使用可吸收线可防止切口疝的发生。术后半年内是腹壁切口疝的高发期，需要注意防护。

Incisional hernia of abdominal wall: analysis of 168 cases

Objective To explore the etiology of incisional hernia of abdominal wall.Methods 168 cases with incisional hernia were analyzed retrospecitively in terms of incision type and size,technique of suture,suture materials,infection of incision,increase of intraabdomial pressure,age,body weight,nutrition and the time of occurrence.Results 135 cases were 51~70 years old among 168 cases with incisional hernia(80.4%).Abdominal longitudinal incision was performed in 145 cases(86.0%).84 cases with incisional hernia were on 2~6 months after operation(50.0%).Bigger incision,improper technique of suture,infection of incision,increase of intraabdominal pressure,heavy body weight,hypoalbumine mia and diabetes mellitus were also easily induced of incisional hernia.Conclusion Transverse incision,strict manipulation and hemostasis,right use of antibiotics,prevention of infection of the incision and increase of intraabdomial pressure,good nutrition supply,less weight and use of absorbable thread are effective in the prevention of incisional hernia.Postoperative half year is high incidence stage of incision hernia and needs to avoid the factors induced incision hernia.
