• Fig GI 23-1 Typical small bowel obstruction on (A) supine and (B) upright projections.

• Fig GI 23-2 Carcinoma of the jejunum causing small bowel obstruction. There is pronounced dilatation of the duodenum and proximal jejunum to the level of the annular constricting tumor (arrow).

• Fig GI 23-3 Gallstone ileus. Upper gastrointestinal series demonstrates the obstructing stone (white arrows) and barium in the biliary tree (black arrow).

• Fig GI 23-4 Impacted bezoar (arrows) causing small bowel obstruction.

• Fig GI 23-5 Intussusception. Coiled-spring appearance (arrow) in jejuno-jejunal intussusception.

• Fig GI 23-6 Meconium ileus. Massive small bowel distention with a profound soap-bubble effect of gas mixed with meconium.28

• Fig GI 23-7 Ileal atresia with microcolon. Barium enema examination shows the colon to be thin and ribbon-like. Note the markedly distended loops of small bowel extending to the point of obstruction in the lower ileum.
