Colorectal stent insertion is an invasive endoscopic procedure. However, there are no reports regarding the incidence of bacteremia with colorectal stent.
This study was to evaluate the risk of bacteremia and infectious complications after stent insertion for colorectal obstruction.
Patients who underwent colorectal stent insertion were enrolled consecutively. Blood cultures were obtained before colorectal stent insertion and at 30 min after the procedure. Patients were monitored for 48 h after colorectal stent insertion to detect the development of infectious complications. Procedural data collected included location of obstruction, degree of bowel preparation, obstructive symptoms, and the time required for the procedure.
Of 64 patients undergoing colorectal stent, four (6.3%) had a positive post-stent blood culture. All patients, including those with positive cultures, remained asymptomatic during the 48 h after the procedure. Site of obstruction, degree of bowel preparation, age, and underlying disease were not different between the two groups. Development of bacteremia was associated with long procedure time (p < 0.05).
Colorectal stent insertion does not induce significant bacteremia in patients with colorectal obstruction. These findings suggest that the routine use of prophylactic antibiotics may not be necessary in colorectal stent insertion.
结直肠支架置入是一种有创的内镜操作。然而，目前尚无关于结直肠支架置入后菌血症发生率的报道。
本研究旨在评估结直肠梗阻支架置入后发生菌血症和感染性并发症的风险。
连续纳入接受结直肠支架置入的患者。在置入结直肠支架前和操作后 30 分钟采集血培养。在置入结直肠支架后 48 小时内监测患者，以检测感染性并发症的发生。收集的操作数据包括梗阻部位、肠道准备程度、梗阻症状以及操作所需时间。
在 64 例行结直肠支架的患者中，有 4 例（6.3%）支架后置血培养阳性。所有患者，包括培养阳性者，在操作后 48 小时内均无症状。两组患者的梗阻部位、肠道准备程度、年龄和基础疾病无差异。菌血症的发生与操作时间长有关（p < 0.05）。
结直肠支架置入不会引起结直肠梗阻患者明显的菌血症。这些发现表明，在结直肠支架置入时常规使用预防性抗生素可能没有必要。
