Endoscopic duodenal stenting is the current standard treatment for malignant gastric outlet obstruction (GOO) in patients with limited life expectancy. However, duodenal stenting is prone to stent dysfunction. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is a novel technique with potentially superior stent patency. We compared clinical success, safety, and stent dysfunction of EUS-GE and duodenal stenting in patients with malignant GOO using propensity score matching.
This international, multicenter, retrospective study analyzed consecutive patients undergoing EUS-GE or duodenal stenting for GOO between 2015 and 2021 in three European centers. Primary outcomes were clinical success (GOO scoring system [GOOSS] ≥ 2) and stent dysfunction (GOOSS ≤ 1 after initial clinical success). A propensity score matching (1:1) analysis was performed using age, sex, underlying disease, disease stage, ascites, and peritoneal carcinomatosis as variables.
214 patients underwent EUS-GE (n = 107) or duodenal stenting (n = 107). After propensity score matching, 176 patients were matched and compared. Technical success rates for EUS-GE and duodenal stenting were 94 % (95 %CI 89 %-99 %) vs. 98 % (95 %CI 95 %-100 %), respectively ( = 0.44). Clinical success rates were 91 % (95 %CI 85 %-97 %) vs. 75 % (95 %CI 66 %-84 %; = 0.008). Stent dysfunction occurred in 1 % (95 %CI 0-4 %) vs. 26 % (95 %CI 15 %-37 %) of patients ( < 0.001). Adverse event rate was 10 % (95 %CI 4 %-17 %) vs. 21 % (95 %CI 12 %-29 %; = 0.09).
EUS-GE had higher clinical success and lower stent dysfunction, with similar safety, compared with duodenal stenting, suggesting that EUS-GE may be preferred over duodenal stenting in patients with malignant GOO.
对于预期寿命有限的恶性胃出口梗阻(GOO)患者,内镜十二指肠支架置入术是目前治疗该病的标准方法。然而,十二指肠支架置入术容易出现支架功能障碍。内镜超声引导下胃肠造口术(EUS-GE)是一种新型技术,具有潜在的更好的支架通畅性。我们通过倾向评分匹配比较了 EUS-GE 和十二指肠支架置入术治疗恶性 GOO 患者的临床成功率、安全性和支架功能障碍。
这是一项国际多中心回顾性研究,分析了 2015 年至 2021 年期间在欧洲三个中心接受 EUS-GE 或十二指肠支架置入术治疗 GOO 的连续患者。主要结局是临床成功率(GOO 评分系统[GOOSS]≥2)和支架功能障碍(初始临床成功后 GOOSS≤1)。使用年龄、性别、基础疾病、疾病分期、腹水和腹膜癌病作为变量进行倾向评分匹配(1:1)分析。
214 例患者接受了 EUS-GE(n=107)或十二指肠支架置入术(n=107)。经过倾向评分匹配后,176 例患者进行了匹配和比较。EUS-GE 和十二指肠支架置入术的技术成功率分别为 94%(95%CI 89%-99%)和 98%(95%CI 95%-100%)( =0.44)。临床成功率分别为 91%(95%CI 85%-97%)和 75%(95%CI 66%-84%; =0.008)。支架功能障碍分别发生在 1%(95%CI 0-4%)和 26%(95%CI 15%-37%)的患者中( <0.001)。不良事件发生率分别为 10%(95%CI 4%-17%)和 21%(95%CI 12%-29%)( =0.09)。
与十二指肠支架置入术相比,EUS-GE 具有更高的临床成功率和更低的支架功能障碍,且安全性相似,提示 EUS-GE 可能优于十二指肠支架置入术,用于治疗恶性 GOO 患者。
