Event Description

Zhou-2020 (evo-c): safety and efficacy of through-the-scope placement of colonic self-expandable metal stents without fluoroscopic guidance: a retrospective cohort study.Retrospective study carried out in patients undergoing endoscopic sems insertion with or without fluoroscopic guidance for malignant large-bowel obstruction in a single tertiary medical center.Sems placement was performed using a 1-channel endoscope with working channel = 3.7 mm diameter (cf-h260; olympus co., tokyo, japan).The stenting procedures are briefly summarized as follows: in the f group, a hydrophilic guidewire and a biliary dilation catheter (cook medical, winston-salem, nc) were inserted through the stricture.Then, the guidewire was removed and a water-soluble contrast agent was injected through catheter to insure proper entry into the proximal lumen and to evaluate the length of the stenosis under fluoroscopy.Then, after the guidewire was reinserted and the dilation catheter was withdrawn, the stent was advanced through the endoscope across the lesion and deployed under endoscopic and fluoroscopic guidance.In the nf group, procedures were otherwise the same as in f group, except that fluoroscopy was not used and contrast agent injection was omitted (off-label use).Guidewire and dilation catheter were considered across the stricture when they were easily advanced without resistance.When resistance was felt, the guidewire tip direction was adjusted.Insertion was retried until easy advance of at least 10 cm of both the guidewire and the catheter.The stent was deployed only under endoscopic monitoring.Stent length must allow for at least 2 cm of additional exposure to each end of the stricture.If one stent was not long enough to cover the obstruction, a second stent was used and at least 3 cm of overlap was obtained.1 patient in the fluoroscopy group experienced stent migration.Stent migration occurred 1 week after stent placement, and this was amended by endoscopic stent reinsertion.
