Pre-operative risk factors for stomal stenosis with Malone antegrade continence enema procedures

Stomal stenosis remains a frustrating complication following creation of the MACE stoma. In the present series, neither a cecal wall flap, nor the stomal site location contributed to SS. Obesity was the only identified statistically significant risk factor that led to SS.Summary Table.
