A 2-year-old boy presents with a 2-day history of abdominal distension, vomiting, and failure to pass stools. He appears uncomfortable and intermittently cries. His mother reports that he has not had any recent illnesses or changes in diet. On examination, his abdomen is distended and tympanitic on percussion, with minimal bowel sounds. He has not passed any gas in the last 24 hours. There is no fever, and the rest of the examination is unremarkable.

Which is the most likely diagnosis?
