Revealing handstand: an anal canal duplication

Key Points

• Anal canal duplication (ACD) is an exceptionally rare congenital anomaly in the gastrointestinal tract, indicating both clinical and surgical challenges.
• In ACD, a second anal or perineal orifice forms behind the native anus, resulting in a tubular tract that ends blindly without connecting to the anorectum.
• Assessment of ACD can involve imaging techniques and clinical examination to differentiate it from other similar anomalies, ensuring accurate diagnosis.
• Understanding ACD is crucial for proper management, as the condition can lead to various complications if left untreated.
