评价腹部超声引导内镜下逆行阑尾炎治疗术对急性非复杂性阑尾炎的临床疗效

Clinical Efficacy of Abdominal Ultrasound-guided Endoscopic Retrograde Appendicitis Therapy for Acute Uncomplicated Appendicitis

目的利用倾向性评分匹配,评估腹部超声引导内镜下逆行阑尾炎治疗术(endoscopic retrograde appendicitis therapy,ERAT)与腹腔镜阑尾切除术(laparoscopic appendectomy,LA)2种手术方式治疗急性非复杂性阑尾炎的临床疗效。方法收集2020年03月至2023年04月云南省第三人民医院收治的441例急性非复杂性阑尾炎患者的病史资料。根据治疗方式差异,将病例分为ERAT组(n=30)和LA组(n=411)。采用倾向性评分匹配(propensity score matching,PSM)均衡组间协变量后,比较2组患者的临床疗效。结果经过PSM,2组共有30对患者匹配成功,且2组基线资料满足可比性要求。ERAT组术后24 h白细胞、中性粒细胞计数、C反应蛋白水平低于LA组,数据差异均有统计学意义(P<0.05)。ERAT组手术时间及总有效率相较于LA组,差异无统计学意义(P>0.05),但ERAT组术中失血量少于LA组,疼痛缓解时间短于LA组,2组之间差异具有统计学意义(P<0.05)。结论腹部超声引导内镜下逆行阑尾炎治疗术效果显著、安全可行,可作为治疗急性阑尾炎切实可行的、有着良好发展前景的无创技术。

Objective To compare the clinical efficacy of abdominal ultrasound-guided endoscopic retrograde appendicitis therapy(ERAT)with laparoscopic appendectomy(LA)for acute uncomplicated appendicitis using propensity score matching.Methods The clinical data of 441 patients with acute uncomplicated appendicitis admitted to the Third People's Hospital of Yunnan Province from March 2020 to April 2023 were collected.The cases were classified based on the differences in surgical method and divided into the ERAT group(n=30)and LA group(n=411).The clinical efficacy of patients was compared between the two groups after reducing confounding bias by propensity score matching(PSM).Results After PSM,a total of 30 pairs of patients in the two groups were successfully matched,and the baseline data of the two groups met the requirements for comparability.At 24 hours after the operation,the ERAT group exhibited lower white blood cells,neutrophil counts,and C-reactive protein levels compared to the LA group,and these differences were statistically significant(P<0.05).There was no significant difference in the operation time and total effective rate between the ERAT group and the LA group(P>0.05).However,the ERAT group had lower intraoperative blood loss and shorter pain relief time compared to the LA group,and these differences were statistically significant(P<0.05).Conclusion Abdominal ultrasound-guided endoscopic retrograde appendicitis treatment is an effective,safe,and feasible technique with good prospects for the treatment of acute uncomplicated appendicitis.
