Introduction

Duodenal obstruction is the second most common site of congenital intestinal obstruction [1]. In the early 1900’s very few patients survived high grade congenital intestinal obstruction. Now mortalities are uncommon and when they occur are typically related to the often serious associated congenital anomalies. Patients with congenital duodenal obstruction can be described by their

  • degree of obstruction whether complete or partially obstructed (fenestrated)
  • underlying etiology of intrinsic and/or extrinsic lesions

(see Classification)

Intrinsic lesions include duodenal atresia, stenosis or diaphragm such as a wind sock web.

Extrinsic duodenal obstruction is secondary to an annular pancreas, preduodenal portal vein, malrotation with Ladd bands and others.
