Repurposing an ACE Malone Channel for Continent Intermittent Catheterization During Re-augmentation Cecocystoplasty: The MACEtrofanoff Procedure.

OBJECTIVE

To describe a surgical alternative option in select patients with neurogenic bladder and a history of Malone antegrade continence enema (MACE) who now require revision augmentation of the bladder, and/or creation of a new continent catherizable urinary channel (CCC).

METHODS

Herein, we describe a novel surgical approach for patients who have had prior MACE creation who subsequently require surgical revision and creation of a new CCC. Rather than the traditional approach of creating a new CCC utilizing bowel, we perform a cecocystoplasty and leave the previously created MACE intact. The prior MACE channel becomes repurposed as the new Mitrofanoff, which we have termed the MACEtrofanoff channel. Concomitant cecostomy tube placement for bowel management can be performed at the time of surgery.

RESULTS

We have successfully performed this procedure in 2 patients with good outcomes to date. This technique does not require the sacrifice of the prior appendix channel, nor require the formation of a new stoma and channel. Patients are able to adapt easily to clean intermittent catheterization through a channel they are already familiar with for their prior antegrade enemas.

CONCLUSION

In select patients, surgeons should consider the MACEtrofanoff procedure to avoid the added morbidity of further bowel mobilization.
