Abstract

Aim: To evaluate the safety and efficacy of partially covered self-expandable metallic stents (SEMSs) in benign pyloric obstruction.

Methods: We retrospectively analyzed data from 10 consecutive patients with peptic ulcer-related pyloric obstructive symptoms (gastric outlet obstruction scoring system (GOOSS) score of 1) between March 2012 and September 2013. The patients were referred to and managed by partially covered SEMS insertion in our tertiary academic center. We assessed the technical success, symptom improvement, and adverse events after stenting.

Results: Early symptoms were improved just 3 d after SEMS placement in all 10 patients. The GOOSS score of all patients improved from 1 to 3. There were no serious immediate adverse events. The overall rate of being symptom free was 90% at a median of 11 mo of follow-up (range: 4-43 mo). Five patients were managed by a rescue SEMS because of failure of previous endoscopic balloon dilatation. Among them, four patients had sustained symptom improvement after the SEMS procedure. During the follow-up period, migration of the SEMS was observed in two patients (20.0%), both of whom had previous endoscopic balloon dilatation before SEMS insertion.

Conclusion: Despite the small number in this study, partially covered SEMSs showed a favorable and safe outcome in the treatment of naïve benign pyloric obstruction and in salvage treatment after balloon dilatation failure.
