Abstract

Background and Aims

Efficacy and safety of endoscopic ultrasound (EUS)–guided placement of lumen-apposing metal stents (LAMSs) has been reported, but the advantage of using 15-mm LAMSs over 10-mm LAMSs has yet to be explored.

Methods

This was an international, retrospective, case-matched study of patients with intra-abdominal abscess who underwent EUS-guided drainage with 15-mm (case) and 10-mm (control) LAMSs from March 2019 through September 2022.

Results

Fifty-one patients underwent EUS-guided drainage using LAMSs (15-mm, 29 [57%]; 10-mm, 22 [43%]). The most common location of the abscess was peripancreatic 43%. Technical success rate was achieved in 97% of the case subjects and 100% of the control subjects (P = .412), and clinical success was achieved in 98% and 96%, respectively (odds ratio, 1.3; P = .089). Adverse events occurred in 7.8% of the case subjects. Patients with 15-mm LAMSs underwent fewer total endoscopic procedures (mean, 2.5 vs 3.6; P < .023).

Conclusions

Both sizes showed similar clinical success and safety profiles, with a significant trend of the need for fewer endoscopic procedures with the 15-mm LAMS.

内镜下超声引导下腹腔脓肿引流使用15毫米与10毫米腔内金属支架：一项国际病例匹配研究。

背景和目的：eus引导下放置腔位金属支架（LAMS）的有效性和安全性已有报道，但使用15毫米LAMS比10毫米LAMS的优势尚待探讨。方法：对2019年3月至2022年9月期间接受eus引导下15mm（病例）和10mm（对照）LAMS引流的腹腔内脓肿患者进行国际、回顾性、病例匹配研究。结果：51例患者行eus引导下LAMS引流术[15-mm 29 (57%), 10-mm 22(43%)]。最常见的脓肿部位是胰腺周围，占43%。病例的技术成功率为97%，对照组为100% (p=0.412)，临床成功率分别为98%和96% (OR 1.3；p = 0.089)。AE发生率为7.8%。15mm LAMS患者接受的内镜手术次数较少(平均2.5 vs.3.6；P < 0.023)。结论：两种尺寸的LAMS均具有相似的临床成功和安全性，且15mm LAMS需要更少的内窥镜手术的显著趋势。
