Abstract:
Objective To evaluate the conditions and risk factors of esophageal stent dys-seal phenomenon (ESDP) .Methods Ninety-eight patients with malignant esophageal obstruction underwent metallic stent placement and 7 patients with ESDP were analyzed.The possible contributing factors,including age,gender,obstruction segment,esophagorespiratory fistula,surgical intervention,radiotherapy,the degree of upper obstruction segment expansion,stent with bellmouth,application of covered stent were investigated.All factors mentioned above were analyzed with Logistic regression analysis.Results ESDP was observed in 7 patients (7/98,7.14%) and defined as a space between the esophageal wall and the proximal part of stent without contrast agent obstruction within stent.The clinical situations of patients with ESDP included dysphagia,bucking and constantly chest pain,especially at foodintake.The results of Logistic regression analysis indicated radiotherapy (P=0.005) and the degree of upper obstruction segment expansion (P=0.017) were significantly correlated with ESDP.Conclusion ESDP is one of the complications after esophageal stent placement.It is prudent to implant esophageal stent for those patients with radiotherapy and significant upper obstruction segment expansion.
