For neonates with imperforate anus, the recommended positioning is prone (on the stomach) with the pelvis elevated or in a frog-leg position, as this helps prevent meconium from tracking upward into the urinary tract and facilitates physical examination of the perineum 1. This positioning should be maintained until surgical evaluation and intervention can be performed, typically within the first 24-48 hours of life. The prone position with buttocks elevated is particularly important for female infants to prevent fecal contamination of the vagina through potential rectovaginal fistulas. While awaiting surgery, the neonate should be kept nil by mouth (NPO), have a nasogastric tube placed for decompression, and receive appropriate intravenous fluids. Broad-spectrum antibiotics may be initiated if there is concern for infection or if surgery is delayed, as highlighted in the study on wound infection after colostomy closure for imperforate anus in children 2. The prone positioning also facilitates physical examination of the perineum, allowing for better visualization of any external abnormalities, fistula openings, or the presence of a "bucket-handle" malformation. Some studies have reported rare associations of imperforate anus with other conditions, such as scimitar syndrome 3, but these do not alter the recommended positioning. Overall, the goal of this positioning strategy is to minimize complications while preparing for definitive surgical management, with the aim of achieving socially acceptable continence in the long term 4. Key considerations in the management of neonates with imperforate anus include:
- Prompt recognition and diagnosis of the condition
- Appropriate positioning to prevent complications
- Surgical evaluation and intervention within the first 24-48 hours of life
- Postoperative care, including bowel care and management of potential complications.
