一次性成像导管辅助金属支架置入在胃十二指肠恶性狭窄中的应用价值

Application value of disposable imaging catheter-assisted metal stent placement in malignant gastroduodenal obstruction

摘要:

目的 探讨一次性成像导管辅助金属支架置入术用于胃十二指肠恶性狭窄的安全性及有效性。方法 回顾性分析2022年4月－2025年10月因胃十二指肠恶性狭窄在该院消化内镜中心行一次性成像导管辅助金属支架置入术治疗的17例患者的临床资料。评估技术成功率、临床成功率、手术时间、术后并发症、症状缓解所需时间和无住院生存期等指标。结果 17例患者均成功放置支架，技术成功率为100.00%（17/17）。1例术后因不能进固态食物，未完全缓解梗阻症状，临床成功率为94.12%（16/17）。手术时间为（17.8±4.4）min。所有患者术后无出血、穿孔、支架移位或脱落等情况。症状缓解所需时间为（19.8±9.2）h，无住院生存期为（12.2±7.3）周。结论 一次性成像导管辅助金属支架置入用于治疗胃十二指肠恶性狭窄，无放射线，是安全、有效的。

Abstract:

Objective To explore the safety and efficacy of disposable imaging catheter-assisted metal stent placement for treating malignant gastroduodenal obstruction.Methods A retrospective analysis was performed on patients diagnosed with malignant gastroduodenal obstruction who underwent disposable imaging catheter-assisted metal stent placement from April 2022 to October 2025. Technical success rate, clinical success rate, procedure duration, postoperative complications, duration until symptom resolution, and postoperative survival time were recorded and analyzed.Results 17 patients underwent the procedure, achieving a technical success rate of 100.00% (17/17). The clinical success rate was 94.12% (16/17), as one patient did not experience complete symptom relief due to an inability to tolerate solid food postoperatively. The mean procedure duration was (17.8 ± 4.4) min. No instances of postoperative bleeding, perforation, stent migration, or dislodgement occurred. The average duration until symptom resolution was (19.8 ± 9.2) h, and the mean postoperative survival time was (12.2 ± 7.3) weeks.Conclusion Disposable imaging catheter-assisted metal stent placement without radiation is safe and effective method for treating malignant gastroduodenal obstruction.
