PURPOSE
When conservative treatments for chronic constipation fail, the Malone antegrade continence enema (MACE) is an
effective alternative surgical option. This study aims to identify surgical risk factors for complications of the MACE
procedure in children.
MATERIAL AND METHODS
We retrospectively reviewed patient charts from 97 pediatric MACE patients at four hospitals. Data collected included:
age, weight status ( obese vs non-obese), open vs. laparoscopic surgery, stomal location, use of a permanent stomal
button. Complications including stomal stenosis, leakage, and infection were analyzed. Two groups were compared. One
group had a permanent Mic-key button placed across the repair. The other group did not. 72 of 74 surgeries without
button use utilized traditional imbrication sutures. None of the 23 surgeries involving button use did.
RESULTS
Twenty two patients (23.7%) developed stomal stenosis and twenty seven patients (27.8%) experienced stomal
leakage. The placement of a stomal button resulted in: 24.8% greater chance of complication (p=.026); 31.9%
greater rate of stomal leakage (p=.003); 16% greater rate of stomal site infection (p=.011) and a 25.4% lower rate of
stomal stenosis (p=.012). In patients without button placement, 32.35% of patients with umbilical stomas experienced
stomal leakage, versus 9.09% of patients with RLQ stomas (p=.019).
CONCLUSIONS
The use of a permanent stomal button across a MACE repair decreases the risk of stomal stenosis but significantly
increases the risk of fecal leakage and infection. The use of imbrication sutures may reduce these risks. While an
umbilical stoma is more cosmetically appealing, it is associated with an increased risk of stool leakage.
