stentfix OTSC was used in five complex cases who already had experienced stent migration and were considered unfit for surgery. Placement of stentfix OTSC resulted in immediate technical success in all patients. Stent migration or fixation-related adverse events did not occur in any patient.
M Conio et al., Gastroenterology Department, General Hospital, Sanremo, Italy, published a case series describing the use of stentfix OTSC in five consecutive patients. All patients had been treated previously with a fully covered self-expandable metal stent (FCSEMS) and experienced FCSEMS migration. All patients were considered unfit for surgery and treated with the stentfix OTSC for fixation of the stent to prevent further migration.
Four patients were male, one patient female. Median age of the patients was 58 years (range 53 – 87 years). Indications for FCSEMS placement were esophageal perforation (n=1), trachea-esophageal fistula (n=1), broncho-esophageal fistula (n=1), advanced esophagogastric adenocarcinoma (n=1) and colorectal anastomotic stricture (n=1). In three patients one stentfix OTSC was placed, in the remaining two patients two stentfix OTSC were placed. Placement of stentfix OTSC resulted in immediate technical success in all patients. Stent migration or fixation-related adverse events did not occur in any patient. Stent and stentfix OTSC dwell time was 60 days (n=1), 90 days (n=1), 105 days (n=1), 150 days (n=1), and unknown (n=1).
The authors concluded that the stentfix OTSC System represents an effective, easy to perform, and safe endoscopic technique for endoluminal fixation of fully covered self-expandable metal stents. Further experience is, however, necessary.
