• W3033156308 abstract "Esophageal stents have traditionally been used for palliation of malignant dysphagia and are increasingly being applied in patients with benign pathology. The expanded use of esophageal stents is likely related to their generally favorable risk-benefit profile. Stent migration is one of the most common adverse events and one of the most common reasons for re-intervention. The goal of this study was to identify the incidence of stent migration and further elucidate factors associated with stent migration. A retrospective chart review was performed for all patients undergoing esophageal stenting for both benign and malignant indications at our institution between May 2008 and November 2018. Patients were excluded from further study if their index stent was not placed at our institution. Statistical analysis was performed using SPSS. A total of 351 index stents were placed during the study period. The majority were placed for a biopsy-proven malignant lesion (282/351; 80%). The median patient age was 68 [60 – 76] years with 270/351 (77%) of patients being male. Only 16/351 (5%) of stents were placed to treat dysphagia secondary to extrinsic compression (eg. mediastinal adenopathy). Stent migration requiring re-intervention occurred in 78/351 (22%) of patients. There was a statistically significant higher incidence of stent migration in cases where the stent was placed for benign disease (24/69; 35%) compared to malignant disease (54/281; 19%) (P = 0.018)). Interestingly, there was no difference in the incidence of stent migration when stents were placed for an intrinsic lesion (2/16; 13%) compared to extrinsic compression ((76/335;22%), (P = 0.338)). There was no difference in stent migration rate when stents placed in the first half of the study period were compared with stents placed in the second half of the study period (27/133; 20% vs 51/218; 23% (P = 0.597)). Patients should be counselled that stent migration remains a common complication requiring re-intervention after placement of an esophageal stent to manage dysphagia. The incidence of stent migration is higher when the stent is placed for a benign condition. In this study, stent placement to treat dysphagia secondary to external compression was not found to increase the risk of stent migration. Routine use of a lateral chest x-ray after placement of an esophageal stent to document the initial stent position could help identify this problem in patients that return with dysphagia after stent placement. In addition to appropriate patient selection, there remains a need for improved stent design and/or endoscopic techniques to mitigate the risk of stent migration." @default.
