Background: Bowel diseases are relatively common in the pediatric age group that sometimes causes growth retardation due to malnutrition and vitamin deficiency. In addition to many bowel-related emergency situations which may cause serious complications in many cases. The main aim of this study was to determine the ability of ultrasonography to diagnose and follow up different cases of bowel diseases, either chronic or acute emergency conditions that may necessitate immediate surgical or medical intervention. Methods: sixty patients ranging between (Preterm up to 14 years) of age were examined in the Radiology department of   Benha children hospital (BENCH) using linear transducer high frequency (12-15 MHz) probe. Results: Through the scheduled study period, forty (60) patients were examined by conventional ultrasound linear transducer. Seventeen (27) of them were female patients and twenty-nine (33) were males, with age ranging from preterm to fourteen years  (neonate up to 2 months (19) , post neonate up to 1 years(15) and children from 1 years to 14 years (26). Validity of US in prediction of different bowel diseases in pediatric as sensitivity of US is 85, specificity is 100 and accuracy is 88.3. Conclusion: Ultrasound was proven to have a major role in different bowel diseases diagnosis in children; especially that it is considered a safe procedure that does not cause non-ionizing radiation exposure. Also, it helps rapid diagnosis without the need for prolonged special preparations.
