The long-term post-surgical outcome of intermediate anorectal malformation in our department

Abstract

Abstract

Background

Posterior sagittal anorectoplasty and laparoscopic-assisted anorectal pull-through are preferred for anorectal malformation (ARM) today, while careful pull-through procedures with sacroperineal approach yield excellent outcomes. This study focuses on a pull-through procedure emphasizing continence mechanism preservation and compares outcomes with historical studies with various procedures.

Methods

Bowel function of patients with intermediate ARM followed up for over 10 years post-surgically was assessed. Data collected included ARM type with the Krickenbeck classification, comorbidities, complications, post-surgical examinations, follow-up, and bowel function at the latest clinic visit. The literature review collected original articles including more than 10 post-anorectoplasty cases which were followed for over 10 years.

Results

Eleven cases were identified, with a median age at anorectoplasty and follow-up length of 6.9 months and 14.4 years. Two fistula recurrences required surgical treatment. Long-term incontinence and constipation were observed in 9% and 45% of the cohort, respectively. Good rectal angulation and a positive rectoanal inhibitory reflex were confirmed in most cases examined. A literature review identified eight studies with various outcome-measuring instruments.

Conclusion

Outcomes of the introduced pull-through procedure were favorable, while the literature review highlights the variation in outcomes of various anorectoplasty.

Evidence Level

Level IV.
