Objective To explore the feasibility and treatment experience of children appendectomy assisted with single hole laparoscope through navel. Methods 70 cases of acute appendicitis were treated by appendectomy assisted with single hole laparoscope through navel. Made a curved incision about 1cm below the navel right margin , inserted 5mm Trocar and la-paroscope, inserted tooth grasping forceps in the same incision close to the Trocar, found the appendix and pulled it out of the abdominal cavity, treated with routine appendectomy and dealed with the stump. Results Operation time was 15~30min, av-erage time was (20 ±3.4)min. Appendix fractured in 4 cases caused by gangrenous appendicitis. 3 cases had more bleeding caused by firm adhesion during separation, and they were turned to conventional three hole laparoscopic appendectomy. Postop-erative anal exhaust time was 10~28h, average time was (15±6.2)h. The postoperative hospital stay was 5~7d, all cases were cured and discharged. No abdominal residual infection and intestinal adhesion happened. The incisions were Ⅰ-grade healing, and had no visible abdominal incision scar with follow-up time of 6 months. Conclusion Children appendectomy assisted with single hole laparoscope through navel is one of the effective methods of the operation treatment for pediatric appendicitis appendix and suppurative acute simple appendicitis, worthy of widespread development.%目的：探讨经脐单孔法腹腔镜辅助小儿阑尾切除术的可行性及治疗经验。方法对70例急性阑尾炎患儿采用经脐单孔法腹腔镜辅助阑尾切除术。脐部右下缘行弧形切口长约1cm，插入5mm Trocar并插入腹腔镜，紧邻Trocar同切口直接置入有齿抓钳，找到阑尾并将其从脐部提出腹腔外用常规方法切除阑尾并处理残端。结果本组70例阑尾炎患儿，手术时间15～30min，平均（20±3.4）min，4例因坏疽性阑尾炎钳夹阑尾时阑尾断裂，3例因粘连牢固分离出血较多术中转为常规三孔法腹腔镜阑尾切除术，术后肛门排气时间10～28h，平均（15±6.2）h。术后住院时间5～7d，均痊愈出院。未发生腹腔残余感染及肠粘连。切口均Ⅰ级愈合，随访半年后患儿腹壁无可见切口疤痕。结论经脐单孔法腹腔镜辅助小儿阑尾切除术对于急性单纯性阑尾炎及化脓性阑尾炎是确切有效的手术方法之一，值得普遍开展。
