Classic divided sigmoidostomy vs loop sigmoidostomy in anorectal malformations: time for change?

Topic overview

Key takeaways

• Loop sigmoidostomy shows no increased risk of prolapse or UTI compared to divided sigmoidostomy in ARM patients.
• Divided sigmoidostomy had significantly higher postoperative complications (48% vs 9%), primarily wound-related issues.
• Loop sigmoidostomy patients achieved faster oral intake and stoma function with shorter hospital stays (8 vs 36 days median).
• Laparoscopic loop sigmoidostomy may be preferable to open divided sigmoidostomy for ARM based on complication profiles.
• Traditional concerns about loop sigmoidostomy complications in ARM are not supported by this comparative study.
