The antegrade continence enema procedure offers convenient enema administration for patients with fecal incontinence and can be performed by a minimally invasive approach that provides shorter hospital stay, less analgesia requirement, and better cosmesis. We present our experience using this approach for fecal incontinence patients and technical modifications to reduce complications.
Following successful management of fecal incontinence through bowel management using a daily rectal enema, 44 patients underwent a laparoscopic-assisted Malone appendicostomy procedure. We reviewed the diagnosis underlying the fecal incontinence, operative technique, duration of surgery, length of hospital stay, and postoperative complications.
The mean age at surgery was 8.6 ± 1.0 years. The diagnoses included anorectal malformations (31), idiopathic constipation (6), Hirschsprung disease (3), and others (4). All the patients underwent a V-V umbilico-appendicoplasty. The cecum was plicated around the base of the appendix in 34 patients (77%); this step was omitted in 10 (23%). The median follow-up was 21 months (range: 3-51 months). Twelve complications were recorded in 9 patients (20.5%)--leakage from the stoma in 1 (2.3%), stomal stenosis in 5 (11.4%), and a combination of both in 3 (6.8%)--with an overall stricture rate of 18.2% (8/44) and leakage rate of 9.1% (4/44). Strictures were managed with minor operative revision. Plicating the cecum was associated with a lower leakage rate compared with the nonplicated group (0/34, 0% versus 4/10, 40%; P = .002). All patients were consistently clean between enemas following their antegrade continence enema procedure.
The umbilical appendicostomy provides a convenient and cosmetic location for enema administration. Cecal plication, which is feasible using a laparoscopic-assisted approach, significantly reduces the leakage rate. Stomal stenoses remains a problem, may be lessened by a V-to-V umbilical to appendix anastomosis, and are easily fixed with a revision.
"Antegrade enema through an appendicostomy was introduced in the early 1990s as an alternative to the rectal enema . The main indication, besides fecal incontinence, has been to increase the child's autonomy in children who already have a good compliance to rectal enemas  . Problems with compliance in young children with incontinence have never been described as an indication for operation. "
[Show abstract][Hide abstract] ABSTRACT: Aim:
The aim of this study is to evaluate postoperatively bowel symptoms of antegrade colon enema through appendicostomies in preschool children with anorectal malformation (ARM).
164 children with ARM operated on with posterior sagittal anorectal plasty were included. The malformations were classified according to Krickenbeck classification. Seventeen children in preschool age had an appendicostomy. The bowel symptoms according to the Krickenbeck follow-up were analysed pre- and postoperatively. All complications were registered. A questionnaire on the use of the appendicostomy was answered.
The median age (range) at the time of the appendicostomy was 4 (1-6) years. The observation time was 5 (0.5-14) years. The main indications for appendicostomy were incontinence and noncompliance to rectal enemas. Postoperatively there was a significant decrease in soiling and constipation (P < 0.001). The total complication rate was 43% with infections (29%), stenosis (12%), and retrograde leakage (0). The median time required for giving enema in the appendicostomy was 45 minutes (range: 15-120) once a day varying from 2 times/week to 3 times/day. And: complications are less frequent than in older children.
Appendicostomy in preschool children with ARM is a way to achieve fecal cleanness before school start. The infection rate was high, but other complications are less frequent than in older children.
[Show abstract][Hide abstract] ABSTRACT: The Malone antegrade continence enema procedure improves quality of life for patients with bowel dysfunction. Stomal leakage has been reported, although no objective scale describes this type of incontinence. The value of cecal imbrication has not been fully elucidated on a large scale.
We retrospectively reviewed pediatric patients who underwent Malone antegrade continence enema by a single surgeon between 2000 and 2010. Detailed information regarding degree and frequency of stomal incontinence was longitudinally recorded and analyzed. A classification system was developed, with grade 0 defined as no stomal incontinence, grade 1 a drop at the stoma or spotting on clothes 1 time or less per month, grade 2 spotting on clothing 2 to 4 times per month and grade 3 any leakage greater than 4 times per month.
The Malone antegrade continence enema procedure was laparoscopic nonimbricated in 51 patients, open nonimbricated in 16 and open imbricated in 12. Mean followup was 3.5 years. Of cases where the appendix was not imbricated stomal incontinence was grade 0 in 69%, grade 1 in 19%, grade 2 in 7.5% and grade 3 in 4.5%. Two patients (3%) requested revision due to stomal incontinence. No patient who underwent Malone antegrade continence enema with imbrication had stomal leakage (p = 0.001).
We reviewed the spectrum of stomal incontinence following Malone antegrade continence enema in 75 patients and developed a new grading scale to help standardize this complication. Imbrication provided stomal continence in all patients. Without imbrication almost 90% had no stomal incontinence or grade 1 leakage after long-term followup.

[Show abstract][Hide abstract] ABSTRACT: The primary aim of this study was to determine if there is a change in the quality of life in pediatric patients with unremitting functional constipation and/or encopresis after undergoing a MACE procedure.
Patients, ages 5 to 18years with unremitting constipation and a normal evaluation, including anorectal manometry and colonic manometry, who opted to undergo a MACE procedure were contacted to participate in the study. Patients with congenital anorectal malformations as well as spinal cord disorders were excluded from the study. The patient's parent/guardian completed the PedsQL(TM) Generic Core Scales QOL survey prior to the operation, 6months, and 12months after the procedure.
A total of 15 consecutive patients meeting protocol criteria were recruited within a period of 20months. The mean age at the MACE procedure was 9.8years (range 7.0-11.1). 5 patients were female. The mean QOL score pre-MACE was 64.1. At 6months post-MACE the mean overall QOL score was 90.2, and it was 92.0 at 12months. All 15 patients at the 6month follow up had significant improvement in their QOL (p=1.9×10(-7)) and all subcategories of QOL were significantly improved as well.
A MACE procedure is of benefit to otherwise normal pediatric patients who have unremitting functional constipation with failure of medical treatment. Our patients had a significant improvement in all QOL categories and overall QOL.
