摘要

Background

The standard of care for gastrojejunal anastomotic stricture following metabolic bariatric bypass surgery is endoscopic balloon dilatation, with revisional surgery as a last line option. The use of lumen-apposing metal stents is expanding to include many gastrointestinal benign and malignant causes in selected cases. They may provide an additional treatment option for post-bypass strictures.

Methods

A single centre, retrospective outcomes analysis was performed over a 3-year period of patients with gastrojejunal anastomotic stricture following metabolic bariatric surgery that was treated with a lumen-apposing metal stent. Primary outcomes assessed were clinical success and perforation. Multiple secondary outcomes were assessed regarding safety and endoscopy use.

Results

Of 88 patients that had lumen-apposing metal stents placed, 20 satisfied selection criteria. Eleven patients (55%) had at least one balloon dilatation prior to stent placement. All patients achieved clinical success 20 (100%) with zero perforations. Technical success was achieved in 19 patients (95%). There were four (20%) recurrent strictures, two stent migrations (10%) (with no associated complication), and one in-stent food bolus obstruction (5%). One patient ultimately required surgical revision (5%). Three patients had endoscopy within 30 days of stent removal (15%), and five patients required unplanned endoscopy with the stent in situ (25%).

Conclusion

Lumen-apposing metal stents within our study show potential as another treatment option for gastrojejunal anastomotic stricture following gastric bypass.
