The study has shown that the most common causes of chronic diarrhea were celiac disease (20%), Crohn’s disease (20%) & mass in ileum (5%). No significant complication was encountered in our studied group of patients apart from capsule retention which was passed spontaneously after several days. The results of our study suggest that capsule endoscopy is of value in the evaluation of chronic diarrhea in patients with previous negative endoscopic or radiologic workup as well as for those with no clinical or laboratory signs of acute or chronic inflammation, for an overall diagnostic yield of 45%.
