  • Title: Endoscopic therapy of benign pyloric stenosis and gastric outlet obstruction.
    Author: Yusuf TE, Brugge WR.
    Journal: Curr Opin Gastroenterol; 2006 Sep; 22(5):570-3. PubMed ID: 16891891.
    Abstract:
    PURPOSE OF REVIEW: To examine the short and long-term success rates of balloon dilation of pyloric stenosis. RECENT FINDINGS: Several large studies have demonstrated high rates of success for the relief of symptoms from pyloric stenosis using through-the-scope balloons. These dilating balloons readily increase the diameter of the stenotic pylorus on average from 6 to 16 mm. Patients who require more than two dilations are at high risk of endoscopic failure and the need for surgical intervention. Rapid re-stenosis rates are observed in patients with malignant pyloric obstruction. Since many patients with benign pyloric stenosis have underlying ulcer disease, helicobacter infection is a relatively common finding. Eradication of this infection at the time of balloon dilation will ensure higher long-term success rates. SUMMARY: In summary, benign pyloric stenosis can be readily treated with endoscopic balloon dilation and should be the first-line therapy.
