    Summary
    This summary is machine-generated.

    Angioplasty successfully dilated surgically created gastrointestinal tract stomata in patients. Procedures involving gastro-gastrostomy or gastro-jejunal bypass showed higher success rates than those with Marlex mesh wrapping.

    Area of Science:

    • Gastroenterology
    • Interventional Radiology
    • Surgical Oncology

    Background:

    • Surgically created gastrointestinal tract stomata can develop stenosis.
    • Angioplasty is a minimally invasive technique for dilating stenotic lumens.
    • Previous methods for managing stomal stenosis had variable success rates.

    Purpose of the Study:

    • To evaluate the efficacy of angioplasty in dilating surgically created gastrointestinal tract stomata.
    • To compare the success rates of angioplasty based on different surgical techniques used for stoma creation.

    Main Methods:

    • Angioplasty dilatation was performed on 23 gastrointestinal tract stomata in 21 patients.
    • Patients were categorized based on the surgical method used for stoma creation: gastric stapling with Marlex mesh wrapping, or gastric stapling with gastro-gastrostomy or Roux-en-Y gastro-jejunal bypass.

  • Success was defined by successful dilatation of the stoma.

    • Main Results:

    • An overall success rate was achieved in the dilatation of 23 surgically created gastrointestinal tract stomata.
    • A 44% success rate was observed in nine patients who underwent gastric stapling with Marlex mesh wrapping.
    • A higher success rate of 77% was achieved in 13 patients who had gastric stapling with either sutured gastro-gastrostomy or Roux-en-Y gastro-jejunal bypass.
    • Successful dilatation was also achieved in one patient with a jejunostomy.

    Conclusions:

    • Angioplasty is an effective technique for dilating stenotic gastrointestinal tract stomata.
    • Surgical techniques involving gastro-gastrostomy or gastro-jejunal bypass appear to yield better outcomes with angioplasty compared to Marlex mesh wrapping for stoma creation.
