Contrast radiography in small intestinal obstruction, a valuable diagnostic tool?
OBJECTIVE
To investigate the diagnostic and therapeutic potential of plain abdominal radiographs and contrast radiography in patients with suspected small intestinal obstruction.


METHODS
Retrospective study.


METHODS
General hospital, Sweden.


METHODS
2357 sets of plain abdominal radiographic casenotes.


METHODS
Analysis of plain abdominal radiographs for small intestinal obstruction. Establishment of the time that subsequent contrast radiography medium took to reach the caecum, and its success rate.


RESULTS
Of the 2357 plain abdominal films 1599 (68%) did not show small intestinal obstruction, 425 (18%) showed intermediate obstruction, and 333 (14%) showed small intestinal obstruction. The water-soluble contrast medium reached the colon in 394/591 (67%) of the cases with intermediate or complete small intestinal obstruction. Although the contrast medium passed to the colon there was remaining abnormality with dilated small intestine in 71/212 (33%) of the cases with intermediate obstruction and in 95/143 (66%) of the small intestinal obstruction group. The time for the contrast medium to reach the colon was 3.4 hours in the normal group, 5.5 hours in the intermediate group and 8.9 hours in the obstruction group.


CONCLUSIONS
The plain abdominal radiographs seem to predict the success of follow-through examinations. Contrast radiography is safe and may have a therapeutic potential in small intestinal obstruction.
