Single institution review of Mini-ACE® low-profile appendicostomy button for antegrade continence enema administration.

ABSTRACT

PURPOSE: Malone antegrade continence enemas (MACE) provide a conduit in which the patient can achieve improved continence, be clean of stool, and gain independence in maintaining bowel function. The Mini-ACE® is a low-profile balloon button that is used to facilitate the administration of antegrade enemas. We sought to describe our practice and short-term outcomes. METHODS: This work is a retrospective review of the Mini-ACE® appendicostomy button from April 2019 to March 2021, with follow-up concluding in October 2021. Patient demographics, colorectal diagnoses, and outcomes were examined. RESULTS: Forty-three patients underwent Mini-ACE® placement; 22 (51%) were male. The average age at Mini-ACE® insertion was 9.2 years (range 3-20 years). The most common diagnoses were functional constipation in 19 (44%), anorectal malformation in 15 (35%), and Hirschsprung disease in 3 (7%), spinal differences 3 (7%). There were no intra-operative complications, but 5 (12%) required prolapse resection. The median length of stay was two days (IQR 1, 4). Patients achieved self-catheterization at 4.5 [3,7] months from MACE creation, with 38 children (88%) reporting excellent success in remaining clean of stool. CONCLUSION: The Mini-ACE® appears to be a safe and low-profile option for antegrade continence enema access. Further research is needed directly comparing complications and patient satisfaction rates between different MACE devices and overall quality of life. LEVEL OF EVIDENCE Level IV.
