BACKGROUND: Colonic stent placement in acute malignant obstruction has proven to be an alternative for emergency surgery. It has been associated with reduced stoma creation and postoperative morbidity. Concerns have risen that manipulation of the tumor and risk of perforation might result in lower disease-free survival. Therefore, we investigated the long-term outcomes of stenting as a bridge to surgery in these patients, with emphasis on clinical success of the stenting procedure. METHODS: We performed a comparative study in the Rijnstate Hospital in Arnhem, The Netherlands. Data were collected from patients who underwent colonic stenting procedures or acute surgical resection due to malignant obstruction performed between 2007 and 2015. Patients treated with palliative intent were excluded. RESULTS: We included 92 patients, 66 underwent stent placement and 26 had an acute surgical resection. Technical and clinical success rates of the stenting procedures were 94% and 82%, respectively. No significant differences in demographic, tumor or stenting characteristics were found for patients with clinically (un)successful stent placement or stent-related perforations. Patients with unsuccessful stent procedures or perforation had higher rates of open procedures and rescue colostomy. Survival rates were similar for patients who underwent stent placements compared with acute resection. We found no significant differences in survival between patients with successful compared with unsuccessful procedures or perforation. CONCLUSIONS: Survival rates of patients who underwent colonic stenting are similar to those of patients who had an acute resection. No negative effects on survival were observed for clinically failed stenting procedures or stent-related perforations.
背景:在急性恶性梗阻中放置结肠支架已被证明是急诊手术的一种替代方法。它与减少造口和术后发病率有关。人们越来越担心肿瘤的操作和穿孔的风险可能导致无病生存率降低。因此,我们研究了这些患者中支架作为手术桥接的长期结果,重点是支架手术的临床成功率。
方法:我们在荷兰阿纳姆的 Rijnstate 医院进行了一项比较研究。数据来自于 2007 年至 2015 年间因恶性梗阻而行结肠支架置入术或急性手术切除的患者。排除姑息治疗的患者。
结果:我们纳入了 92 例患者,66 例行支架置入术,26 例行急性手术切除。支架置入术的技术和临床成功率分别为 94%和 82%。在临床(非)成功的支架置入或支架相关穿孔患者中,支架置入术的人口统计学、肿瘤或支架特征无显著差异。支架操作不成功或穿孔的患者开放手术和抢救性结肠造口术的发生率较高。与行急性切除术的患者相比,行支架置入术的患者的生存率相似。我们发现支架置入术成功与不成功的患者之间以及支架相关穿孔与未穿孔的患者之间的生存率无显著差异。
结论:行结肠支架置入术的患者的生存率与行急性切除术的患者相似。临床失败的支架置入术或支架相关穿孔对生存没有负面影响。
