目的   回顾分析高原地区儿童阑尾炎术后早期炎性肠梗阻的临床特征，总结治疗经验。方法   回顾分析青海省妇女儿童医院2019—2023年收治的49例儿童阑尾炎术后早期炎性肠梗阻病例资料。结果   纳入研究的49例患儿，阑尾炎发病时间3～8 d，平均（5.38±1.25）d，术后出现肠梗阻时间3~11 d，平均时间（4.81±1.70）d，其中48例经过保守治疗后梗阻解除，恢复排气、排便，肠功能恢复时间4~13 d，平均（5.93±2.49）d，1例经积极保守治疗后病情进展，最终经手术治愈。49例患儿均顺利治愈出院，住院时间10～26 d，平均（15.69±3.79）d。术后随访1～2年，患儿饮食、排便均无异常。结论   高原地区儿童阑尾炎术后早期粘连性肠梗阻预防是关键，采取保守治疗同样可获得较高的治愈率，若保守治疗无效或病情进展应及时积极采取手术治疗。

       Objective  To review the clinical characteristics of early postoperative inflammatory small bowel obstruction（EPISBO） in children with appendicitis in plateau area and summarize the treatment experience．Methods  The data of 49 cases of appendicitis EPISBO in children admitted to Qinghai Women and Children’s Hospital from 2019 to 2023 were  retrospectively analyzed．Results  The onset time of appendicitis was 3-8 days，with an average of（5.38±1.25）days，and the time of intestinal obstruction was 3-11 days after surgery，with an average of（4.81±1.70）days．After conservative treatment，48 cases were relieved of obstruction，resumed exhaust and defecation，and intestinal function recovered in 4-13 day，average（5.93±2.49）d，1 case had progression after conservative treatment，and was cured by surgery．All the 49 children were successfully cured and discharged．The length of hospital stay was 10-26 days，with an average of（15.69±3.79）days．Postoperative follow-up of 1 to 2 years showed normal eating and bowel movements．Conclusions  The prevention of EPISBO in children with appendicitis in plateau area is the key．Conservative treatment can also achieve a higher cure rate．If conservative treatment is ineffective or the disease progresses，timely surgical treatment should be provided．
