Pitfalls in the use of barium enema in early appendicitis in children.
Appendicitis remains the most common intraabdominal indication for surgery in children. Recently, barium enema has been helpful in increasing the accuracy of diagnosis in difficult cases. Experience with 202 barium enemas in children with abdominal pain entertaining the diagnosis of acute appendicitis revealed some of the problems encountered in using this procedure as a diagnostic tool. Of the 66 children who underwent surgery, there were 32 children who were felt to have a positive barium enema and 31 of these turned out to have acute appendicitis. In the group that had negative barium enemas, there were 3 false negatives and 2 of these children had early perforations by the time of their surgery. The third group were equivocal barium enemas and they pointed out the difficulty in obtaining a normal barium enema in a child who does not have appendicitis. It was felt that the use of barium enema as an adjunct was helpful especially if it were positive, but a negative barium enema could not be relied upon to delay surgery in the child with right lower quadrant peritoneal signs.
