Late-onset intestinal obstruction in cystic fibrosis--meconium ileus equivalent.

Four patients who suffered from cystic fibrosis and late-onset bowel obstruction (meconium 
ileus equivalent), and who were treated by surgery, are discussed. The 
importance of early correct diagnosis is stressed, since surgery may be 
prevented if bowel washouts and oral medications are given before the 
condition becomes complicated.
