Abstract
26 patients with prior history of RYGBP for morbid obesity presented with symptoms of gastric outlet obstruction Symptoms included accelerated weight loss n = 22 nausea/vomiting n = 26 dehydration n = 5 and dysphagia n = 2 Endoscopic dilatation was performed using throughthescope dilating balloons 8–15 mm Following dilatation a steroid solution was injected to prevent restenosisPatients underwent 1–7 dilating sessions mean 27/patient at 2week intervals Estimated stoma diameter prior to dilation ranged from 1 mm to 8 mm mean 35 Following dilation diameter of the stoma increased to 10 to 15 mm mean 124 at final endoscopy In patients requiring a single dilating session n = 7 predilation stoma size was a mean 58 mm range 3–8 mm which increased to a mean of 127 mm range 10–15 mm In patients requiring multiple dilating sessions n = 19 predilation stoma size was a mean of 27 mm range 0–4 mm which increased to a mean of 122 mm range 10–14 mm 25 of 26 patients had good longterm response with followup of 6–38 months mean 26 No treatmentrelated complications occurred All had appropriate weight loss as determined at the bariatric clinic following endoscopic therapyOf the complications following bariatric surgery that are amenable to endoscopic therapy stomal stenosis appears to be relatively common Endoscopic balloon dilation is an effective nonsurgical method for treatment of stomal stenosis with no complications observed in this the largest reported series
