What the experts said
Traditional teaching holds that divided colostomy should be performed for anorectal malformations to prevent stool flowing down that could cause urinary tract infection.
Dr. Robert Baird performed a meta-analysis of multiple studies comparing divided colostomy versus loop colostomy for anorectal malformations.
The meta-analysis found no statistically significant difference in urinary tract infection incidence between divided colostomy and loop colostomy.
Some individual studies within the meta-analysis showed a difference in UTI rates, but the overall meta-analysis showed no statistical difference.
Loop colostomies had a significantly higher stoma prolapse rate compared to divided colostomies.
Skin excoriation, stoma retraction, peristomal hernia, wound infection, and stoma stricture showed no statistical difference between loop colostomy and divided colostomy.
