A newborn presenting with intestinal obstruction and constipation showed, on abdominal X ray, multiple air fluid levels. The diagnosis is not likely to be:: (A) Pyloric obstruction, (B) Duodenal atresia, (C) Ileal atresia, (D) Ladd's bands
Answer is A. In Pyloric obstruction there will be only single air fluid level. For multiple air fluid levels on X ray obstruction should be distal to duodenal bulb. Ref: Walker's Pediatric Gastrointestinal Disease: Physiology, Diagnosis and Management By Ronald E. Kleinman, 2008, Page 122
