A newborn baby boy, delivered at full term via an uncomplicated vaginal birth, was noted to have abdominal distension and absence of stool passage within the first 24 hours of life. The baby was otherwise alert, with normal feeding and stable vital signs. However, on physical examination, the attending physician discovered that there was no visible anal opening.

Further assessment confirmed a diagnosis of imperforate anus. A nasogastric tube was inserted to relieve the abdominal distension, and the baby was started on IV fluids. A pediatric surgeon was consulted, and a contrast X-ray was performed to evaluate the level of obstruction and any potential associated anomalies.

Given the diagnosis, the baby was scheduled for a diverting colostomy as an initial step, with plans for future corrective surgery. Genetic and cardiac evaluations were also planned, as imperforate anus can be associated with other congenital abnormalities. The parents were counseled regarding the condition and the planned treatment approach, including the need for multiple surgeries and long-term follow-up.

The baby underwent a successful colostomy and was stable postoperatively. The family was discharged with instructions for colostomy care and scheduled for regular follow-ups to plan for definitive surgical repair in the coming months.
