Membranous duodenal stenosis in infants presents differently than duodenal atresia, often leading to delayed diagnosis. Early surgical intervention shows good outcomes, supporting its classification as a distinct entity.

Area of Science:

  • Pediatric Surgery
  • Gastroenterology
  • Congenital Malformations

Background:

  • Membranous duodenal stenosis is a rare congenital anomaly.
  • It can be misdiagnosed as duodenal atresia, delaying appropriate treatment.
  • Understanding its unique presentation is crucial for timely intervention.

Purpose of the Study:

  • To report the clinical experience of patients with membranous duodenal stenosis.
  • To analyze treatment strategies and outcomes.
  • To differentiate membranous duodenal stenosis from duodenal atresia.

Main Methods:

  • Retrospective analysis of 16 patients treated for membranous duodenal stenosis.
  • Review of presenting symptoms, associated malformations, surgical procedures, and postoperative courses.

  • Comparison of clinical presentation with duodenal atresia.

    • Main Results:

    • Non-bile-stained vomiting was the predominant presenting symptom.
    • Associated malformations, including Down syndrome, were common.
    • Surgical procedures included partial excision with duodenoplasty, duodenojejunostomy, or duodenoplasty alone.
    • No lethal complications occurred postoperatively; one late stricture was noted.

    Conclusions:

    • Membranous duodenal stenosis has distinct clinical features compared to duodenal atresia.
    • Misinterpretation can lead to delayed diagnosis.
    • It should be recognized and managed as a separate entity.
