双管引流在坏疽穿孔性阑尾炎及阑尾周围脓肿手术中的应用

Application of double-tube drainage in patients with complicated appendicitis

目的比较坏疽、穿孔性阑尾炎及阑尾周围脓肿术后双管引流和非引流的临床疗效。方法选择2006年1月至2008年8月我院收治的坏疽、穿孔性阑尾炎及阑尾周围脓肿80例,随机分为两组:双管引流组38例,非引流组42例;比较两种方法的腹腔脓肿发生情况、伤口感染率和住院时间。结果非引流组发现1例腹腔脓肿,伤口感染率明显较双管引流组高(P<0.01);非引流组住院时间为(10.3±2.6)d,双管引流组住院时间为(7.2±1.9)d,两组比较差异有统计学意义(P<0.05)。结论对于坏疽、穿孔性阑尾炎及阑尾周围脓肿,双管引流可以缩短病人住院时间,有效避免腹腔脓肿形成和伤口感染发生。

Objective To compare the clinical effectiveness of double-tube drainage management vs non-drainage in patients with complicated appendicitis. Methods Hospital records of 80 patients who underwent appendectomy between Jan.2006 and Aug. 2008 were reviewed. Double-tube drainage management was done in 38 patients（double-tube drainage group）, and the remaining didn＇t receive drainage（non-drainage group）. Incidence of surgical wound infection（SWI）, and abdominal abscess and length of stay （LOS）were compared between two groups. Results Patients with non-drainage had a higher incidence of SWI（P〈0. 01）and longer LOS[（10. 3 ± 2. 6） days vs（7. 2 ± 1.9）days,P〈0. 05]. There was one case of abdominal abscess in non-drainage group. Conclusion Abdominal abscess and SWI can be avoided for complicated appendicitis with double-tube drainage management, and LOS was shorter.
