目的：观察阑尾炎腹腔镜微创手术切口感染情况。方法选取2014年1月－2016年4月在医院进行治疗的急性阑尾炎患者319例，根据治疗方案的不同将所有患者随机分为2组，其中对照组161例患者采用常规开腹手术进行治疗；试验组158例患者采用腹腔镜微创手术进行治疗。对手术过程中2组患者的术中出血量、手术时间及住院时间等相关临床指标进行对比分析。术后对患者进行为期4周的随访，统计2组患者在术后的感染发生率及不同阑尾炎病理类型切口感染率。结果2组手术时间比较无显著性差异（P＞0．05），但试验组患者的术中出血量少于对照组，住院时间短于对照组，切口感染发生率低于对照组，化脓性阑尾炎的切口感染率显著低于对照组，差异均有统计学意义（P＜0．05）。但2组单纯性阑尾炎及坏疽性阑尾炎的切口感染率无显著性差异（P＞0．05）。结论腹腔镜微创手术能显著降低阑尾炎手术患者术后切口的感染发生率，并且还显著减少术中出血量并缩短住院时间，减少治疗费用，值得临床推广应用。“,”Objective To analysis the influence of laparoscopic minimally invasive surgery on the incision infection of patients with appendectomy .Methods Selected 319 cases patients with appendicitis from January 2014 to April 2016.Accord-ing to the treatment programs,319 cases patients were divided into test group (158 cases) and control group(161 cases).Con-trol group was treated by conventional laparotomy .Test group was treated by laparoscopic minimally invasive surgery .After treatment,compared the intraoperative blood loss ,operation time,hospitalization stays and incision infection in 2 groups.Re-sults The operation time in 2 groups was no statistic significantly (P>0.05).The intraoperative blood loss and incision infec-tion rate were less than those in control group ,hospitalization stays was shorter than that in control group ,the difference were statistic significantly(P<0.05).The incision infection rate of suppurative appendicitis in test group was lower than that of control group,the difference was statistic significantly (P0.05).Conclusion Laparoscopic minimally invasive surgery in treatment of appendicitis can reduce the incision infection rate ,reduce the amount of bleeding patients ,shorten the patient′s hospital stay ,reduce treatment costs ,worthy of clinical application .
