Duodenal Obstruction secondary to adhesions
Duodenal obstruction in adults may be secondary to chronic pancreatitis (5% of patients with chronic pancreatitis experience symptomatic duodenal stenosis), pancreatic cancer, annular pancreas, Crohn’s disease (2-4% of patient’s with Crohn’s), vascular compression (SMA syndrome), and hematoma secondary to trauma.
Duodenal obstruction in the pediatric or neonatal population is often secondary to a congenital anomaly. Malrotation with midgut volvulus and/or Ladd bands, duodenal atresia or stenosis, intraluminal diverticula (may manifest at any age), duplication cysts, and annular pancreas (also presents in adults) may present with duodenal obstruction.
Patients present with nausea, vomiting, abdominal pain, and weight loss. Diagnosis is confirmed radiologically with plain film, upper GI barium study, or CT, depending on the etiology. Treatment is often surgical.
