# Triplication of the Sigmoid: A Rare Incidental Finding in Association With an Anorectal Malformation During Colostomy Closure

## TL;DR

A rare case of triplicated sigmoid colon was found in a child with an anorectal malformation during a surgical procedure.

## Contribution

The report highlights a rare congenital anomaly and its surgical management in the context of anorectal malformation.

## Key findings

- Triplication of the sigmoid colon was discovered during colostomy closure in a patient with anorectal malformation.
- Catheters were used to identify the native bowel lumen before excising the triplicated segment.
- The case illustrates the complexity of managing GI anomalies during anorectal malformation surgery.

## Abstract

This case report presents a rare occurrence of triplication of the sigmoid, an unusual congenital anomaly, in a nine-month-old male with a known history of anorectal malformation. The patient, previously diagnosed with anal atresia and a rectourethral (prostatic) fistula, was admitted for the closure of his divided sigmoidostomy as the final step in correcting his anorectal malformation. Unexpectedly, during the release of the distal stoma, the presence of three distinct bowel lumens was discovered. To discern the native bowel, catheters were introduced into each lumen before proceeding with the excision of the triplicated sigmoid and subsequent stoma closure. This case underscores the complexity of diagnosing and managing unusual GI anomalies in the context of anorectal malformations, emphasizing the challenges encountered during surgical interventions.
