The Malone antegrade continence enema procedure: quality of life and family perspective

Outcomes of children with constipation and autism spectrum disorder treated with antegrade continence enemas

BACKGROUND

Treatment of functional constipation (FC) in children with autism spectrum disorder (ASD) is challenging due to sensory and behavioral issues. We aimed to understand whether antegrade continence enemas (ACEs) are successful in the treatment of FC in children with ASD.

METHODS

A single-institution retrospective review was performed in children diagnosed with ASD and FC who underwent appendicostomy or cecostomy placement from 2007 to 2019. Descriptive statistics regarding soiling and complications were calculated.

RESULTS

There were 33 patients included, with a median age of 9.7 years at the time of ACE initiation. The average intelligence quotient was 63.6 (SD = 18.0, n = 12), the average behavioral adaptive score was 59.9 (SD = 11.1, n = 13), and the average total Child Behavioral Checklist score was 72.5 (SD = 7.1, n = 10). Soiling rates were significantly lower following ACE initiation (42.3% vs. 14.8%, p = 0.04). Behavioral issues only prevented 1 patient (3.0%) from proper ACE use. Eleven patients (36.6%) were able to transition to laxatives. There were significant improvements in patient-reported outcomes measures and quality of life.

CONCLUSION

Placement of an appendicostomy or cecostomy for management of FC in children with severe ASD was successful in treating constipation and improving quality of life.

Psychosocial factors impacting antegrade continence enema outcomes in pediatric patients

BACKGROUND

Children with constipation and encopresis are often treated with medication and behavioral approaches. When constipation persists, surgical interventions such as antegrade continence enema (ACE) procedures are considered. Many children benefit from these procedures; however, some children continue to have incontinence, experience complications, or discontinue the use of the ACE stoma. There is some evidence in the literature to indicate that psychosocial factors can have an impact on ACE outcomes; however, standardized biopsychosocial guidelines related to ACE candidacy and surgery do not currently exist.

PURPOSE

The purpose of this review is to summarize the research to date on psychosocial factors related to ACE treatment outcomes and complications. Identifying what is known and what limitations remain can support future research to inform development of guidelines for pre-procedure evaluations. Psychosocial pre-procedure evaluations could help to inform eligibility for the procedure as well as interventions to enhance outcomes for children at increased risk for poor outcomes or complications from ACE. Age, psychiatric symptoms, and adherence to the ACE flush regimen were some of the factors identified in the literature as impacting ACE outcomes; however, there is limited research in this area.

People with spina bifida use their MACE on long-term follow-up: A single institutional retrospective cohort study

OBJECTIVE

While the Malone antegrade continence enema (MACE) facilitates bowel movements in patients with spina bifida (SB) and neuropathic bowel, little is known about its long-term use. We aimed to assess long-term MACE use and potential risk factors for disuse.

METHODS

All patients with SB who underwent MACE procedures at our institution were retrospectively reviewed. Main outcome was MACE disuse (no longer catheterizing the MACE for antegrade enemas) based on self-report on a clinic questionnaire, or medical record for patients last seen before introducing the questionnaire 5 years ago. Survival analysis used two timeframes: time after surgery (Analysis 1) and chronological age: accounting for older children reaching adulthood earlier (Analysis 2).

RESULTS

Overall, 411 patients (54% female, 78% shunted, 65% augmented) underwent a MACE procedure at median 7.9 years old (median follow-up: 8.4 years). Thirty-three (8%) patients no longer used their MACE. Most common reasons for doing so were channel/stomal stenosis (61%) and excision at colostomy or other abdominal surgery (12%). Bowel management afterwards included oral agents ± enemas (55%), Chait tube (30%), colostomy (12%). After correcting for differential follow-up, 90% of participants used their MACE at 10 years and 87% at 15 years after surgery. Based on chronological age, 97% used their MACE at 15 years old, 92% at 20 and 81% at 30 (Summary Figure). On multivariate analysis, umbilical MACEs were 2.4 times more likely to be disused than right lower quadrant MACEs (p = 0.04). Without correcting for chronological age (Analysis 1), patients undergoing MACE surgery at older ages were more likely to stop MACE use (p = 0.03). However, after accounting for chronological age (Analysis 2), patients undergoing a MACE procedure at older ages were no more likely to stop its use (p = 0.47, Figure). Gender, SB type, shunt status, mobility status, bladder augmentation or a urinary catheterizable channel were not associated with stopping MACE use (p ≥ 0.10).

COMMENT

Participants were regularly followed in multi-disciplinary SB clinics. We did not assess continence, satisfaction or long-term urinary channel use, making it premature to recommend optimal stomal locations.

CONCLUSIONS

Most patients with SB followed by a multi-disciplinary team continue using their MACE; 1% stopped MACE use annually, particularly after adolescence. This strongly suggests it is an effective bowel management method and transitioning to self-care plays a role in maintaining long-term MACE use. Umbilical MACEs may be at high risk of disuse, but all people with a MACE can benefit from support as they transition to adult care.

Simultaneous placement of fecal and urinary continent channel stomas in the umbilicus: Single-center experience

INTRODUCTION

In patients with urinary continent channel (UCC) and Malone Antegrade Continent Enema (MACE) procedures, two separate abdominal stomas are needed. The umbilicus is a preferred site for single channel stomas given the ability to conceal the stoma. However, there are no studies describing outcomes of both stomas being created in the umbilicus. We aimed to describe our experience in patients who underwent UCC and MACE stomas both placed in the umbilicus.

METHODS

A retrospective review from 2009 to 2020 was performed in our institution for patients who underwent the creation of UCC and MACE stomas simultaneously in the umbilicus. The variation in the technique involves two V-skin shaped flaps in the umbilicus; the MACE and UCC stomas are delivered from both flaps and placed at the right and left side respectively. Patients with greater than 3 months of follow-up were included in the study.

RESULTS

There were 17 patients identified with the median age of 13.5 years and a median follow-up of 32.8 months. The mean BMI percentile was 89.5%. Monti technique and split appendix with cecal extension were utilized in 8 (47.1%) and 7 (41.2%) patients respectively and 13 (76.5%) patients required concurrent urological procedures. All channel-related complications occurred within a mean time of 15.7 months. Skin-level stenosis in the MACE occurred in 5 (29.4%) events, and all were successfully managed by placing an indwelling catheter for up to two weeks. There were 2 (11.8%) complications related to UCC, which required subfascial minor surgical revision. The rate of patients with symptomatic UTI decreased 35.3% postoperatively, and no new onset of UTI occurred in patients without a prior history of UTI. During follow-up, all patients remained dry between CIC, however one had occasional leakage related to delay in catheterization. Total fecal continence was achieved in 14 (82.3%) patients. Additionally, 3 (16.6%) patients experienced improvement in fecal continence with sporadic soiling episodes.

COMMENTS

Placement of UCC and MACE stomas in the umbilicus demonstrate a percentage of complication of 7/34 (20.6%) with only 2 patients requiring surgical intervention, comparable to the standard. UTI rate decreased in patients with a prior history of UTI. We believe the patients' perspective and degree of satisfaction will fully determine the benefits of this technique.

CONCLUSIONS

Simultaneous UCC and MACE stomas placed at the umbilicus showed good functional outcomes and similar complication rates to traditional approach where stomas were placed separately in the abdominal wall.

Long-term usage pattern and satisfaction survey of continent catheterizable channels

INTRODUCTION

We investigated the long-term usage pattern and satisfaction of continent catheterizable channels (CCCs).

METHODS

From 2005 to 2018, CCCs, including Mitrofanoff and antegrade continent enema (ACE) channels, were made in 67 patients (Mitrofanoff in 21 patients, ACE channels in 43 patients, and both in three patients) in our institution. An online survey was conducted for these patients in order to assess usage pattern, continent status, difficulty in usage, and patient satisfaction.

RESULTS

Sixteen (66.7%) out of 24 patients with the Mitrofanoff channel and 39 (84.7%) out of 46 patients with the ACE channel completed the online survey. In the Mitrofanoff channel group, 10 (62.5%) patients had spina bifida, two (12.5%) had Hinman syndrome, one (6.3%) had posterior urethral valves, and three (18.8%) had urethral trauma or atresia. Additionally, the mean age of the patients at the time of surgery was 10.0 years, and the median follow-up duration was 10.9 years. All patients were using the Mitrofanoff channel to perform clean intermittent catheterization (CIC). Eleven patients (68.8%) had difficulty with catheterization, mostly at the stomal site. Most patients conducted CIC more than four times a day (13, 81.3%). Regarding urination status, seven patients (43.8%) responded that they were satisfied and nine (56.2%) responded they were neutral. In the ACE channel group, 35 patients (89.7%) had spina bifida, seven (17.9%) had cloacal anomalies, and 26 (66.7%) had anorectal malformations. The mean age of the patients at the time of surgery was 8.4 years, and the median follow-up period was 7.4 years. Two (5.1%) patients were no longer using their ACE channels, but 15 (38.5%) patients were still using their channels almost daily. Twenty-eight (71.8%) patients complained that performing enema was time-consuming, and seven (17.9%) patients reported pain when performing ACE and fecal incontinence. Most patients were satisfied with their defecation status (23, 59%), 15 (38.5%) were neutral, and one (2.6%) was dissatisfied.

CONCLUSIONS

While most patients who had either Mitrofanoff or ACE channels were still using their channels effectively, approximately half of the patients with CCCs demonstrated neutral satisfaction with their current status; this shows a poor result compared to previous reports. Considering the results of our patient-based study, thorough explanations should be provided to patients who are candidates for Mitrofanoff and ACE procedures; additionally, the discomfort related to the procedures should be comprehensively assessed during follow-up consults.

Troubleshooting problems with antegrade continent enema flushes: The Indiana university algorithm

INTRODUCTION

Antegrade continence enemas have transformed treatment and improved the quality of life in children with neuropathic bowel, refractory constipation and fecal incontinence. However, it can often be difficult to manage problems that arise with ACE flushes.

OBJECTIVE

We report the use of an online tool designed for nurses to help troubleshoot calls for problems associated with antegrade continence enema (ACE) flushes as well as update our algorithm for managing refractory constipation/fecal incontinence in a large single institution experience.

STUDY DESIGN

We developed an online tool based on our management protocol for managing refractory constipation/fecal incontinence (Summary Figure). Patient frequency and bother was assessed prior to the intervention and at one month after the intervention using 5- and 4-point Likert scales respectively. Patient demographics, MACE/Chait information, type of difficulty, volume of flush, and use of additives were recorded. Nurses were also interviewed prior to using the tool and 14 months after its development with regards to taking these phone calls and the helpfulness of the tool.

RESULTS

Over 14 months, the nurses received 22 patients calls via the nursing triage line regarding ACE flush problems and prospectively collected data. Half reported multiple episodes of fecal incontinence. Other complaints included no response to flush (8, 36.4%), occasional episodes of liquid fecal incontinence (2, 9.1%) and time of flush exceeding 60 min (1, 4.5%). While patients did not report decreased frequency of problems as a result of nurse troubleshooting using the ACE algorithm (2.5 vs. 2, p = 0.55), patients did report a significant improvement in their bother scores (4 vs. 2, p = 0.02). All but one patient reported that the recommendation was "some" or "a lot" helpful on follow up interview. The nurses all indicated that the tool helped "some" or "a lot."

DISCUSSION

The antegrade continence enema is valuable in managing neurogenic bowel, refractory constipation, and fecal incontinence, however, some patients experience problems with flushes that can often be difficult to manage.

CONCLUSION

Patients reported less bother with their bowel issues after using our algorithm for managing refractory constipation/fecal incontinence and nurses reported that the tool was helpful.

Usefulness of the Monti-Malone procedure as a reconstruction of the antegrade continence enema procedure: a case report

Background

The antegrade continence enema (ACE) procedure is effective for severe constipation in patients with spina bifida and can improve quality of life (QOL). The Monti–Malone procedure (MM), which is a method of creating an enema tract from the colon, has been reported as an alternative to the ACE procedure when the appendix cannot be used. We report the usefulness of MM as a reconstruction of the antegrade continence enema procedure.

Case presentation

Our patient was a 22-year-old man with congenital spina bifida and hydrocephalus. Ventriculoperitoneal (VP) shunt surgery was performed immediately after birth, and preventative appendectomy was carried out during VP shunt repair when 4 months old. At 5 years of age, the ACE procedure using a balloon-button gastrostomy tube was performed for intractable chronic constipation. Simple management was expected, but after 17 years of age, he experienced increased stool leakage around the gastrostomy tube and his QOL declined due to difficulty in managing the ACE. Therefore, reconstruction of the ACE procedure by MM was performed. After reconstruction, the ACE performed well without any complications. The patient is currently satisfied because management of the ACE is easier than before, and his QOL has markedly improved without stool leakage and dermatitis.

Conclusions

MM is less likely to cause complications and is useful as a reconstruction of the ACE procedure.

The impact of bowel management on the quality of life in children with spina bifida with overactive bladder and detrusor sphincter dyssynergia

OBJECTIVE

The aim of the study was to assess the impact of bowel management on the quality of life in children with spina bifida with overactive bladder and detrusor sphincter dyssynergia.

MATERIALS AND METHOD

The research was carried out over the 2014-2017 period, during which 70 patients with spina bifida with overactive bladder and detrusor sphincter dyssynergia were observed. The first group (group 1) consisted of 35 patients who were administered bowel management combined with anticholinergic medication therapy and CIC. The second group (group 2) consisted of 35 patients who were treated only with anticholinergic medication therapy and CIC. Bowel management included daily enema, laxative application, and a special diet, with a view of treating constipation and fecal incontinence that was estimated on the basis of Roma III criteria, the echosonographically determined transversal rectal diameter, and encopresis frequency. The effects of the administered bowel management on urinary incontinence were estimated on the basis of the average dry interval between two CICs. Regarding the quality of life, a KINDL questionnaire was used for children and parents to determine the overall quality of life, but also the various aspects of the quality of children's life (physical well-being, emotional well-being, self-confidence, family, friends, school, disease). The test score ranges from 0 to 100, where 0 is the lowest and 100 denotes the highest quality of life. The follow-up period of every patient was one year.

RESULTS

At baseline, there was no significant difference between the groups regarding demographic and clinical features (p > 0.05). After one year, treatment by bowel management demonstrated significant improvement for both fecal constipation/incontinence and urinary incontinence (p < 0.001). The bowel management group showed improved overall quality of life in contrast to the group without bowel management 88.9 ± 7.1 vs. 55.4 ± 11.4 (p < 0.001, assessed by parents) and 84.5 ± 8.9 vs. 53.4 ± 12.5 (p < 0.001, assessed by children), respectively. Moreover, the positive impact of bowel management on quality of life was confirmed for all domains of the quality of life (physical well-being, emotional well-being, self-confidence, family, friends, school, disease), (p < 0.001 for all), both by the parents' and the children's assessment.

CONCLUSION

Administering bowel management considerably alleviates the symptoms of fecal and urinary incontinence and considerably improves the quality of life. Bowel management should be considered as an integral part of treatment of children with spina bifida.

Malone Antegrade Continence Enemas vs. Cecostomy vs. Transanal Irrigation-What Is New and How Do We Counsel Our Patients?

PURPOSE OF REVIEW

No gold standard exists for managing neurogenic bowel dysfunction, specifically in individuals with spina bifida. Since the International Children's Continence Society published its consensus document on neurogenic bowel treatment in 2012, an increased focus on why we must manage bowels and how to improve our management has occurred. This review provides updated information for clinicians.

RECENT FINDINGS

A surge in research, mostly retrospective, has been conducted on the success and satisfaction of three types of management for neurogenic bowel. All three management techniques have relatively high success rates for fecal continence and satisfaction rates. Selection of which treatment to carry out still is debated among clinicians. Transanal irrigation is a safe and effective management option for neurogenic bowel that does not require surgery. Antegrade enemas can be carried out via cecostomy tube or Malone antegrade continence enema with similar fecal continence outcomes.

A comparison of Malone appendicostomy and cecostomy for antegrade access as adjuncts to a bowel management program for patients with functional constipation or fecal incontinence

BACKGROUND

Appendicostomy and cecostomy are two approaches for antegrade enema access for children with severe constipation or fecal incontinence as adjuncts to a mechanical bowel management program. Each technique is associated with a unique set of complications. The purpose of our study was to report the rates of various complications associated with antegrade enema access techniques to help guide which option a clinician offers to their patients.

METHODS

We reviewed all patients in our Center who received an appendicostomy or cecostomy from 2014 to 2017 who were participants in our bowel management program.

RESULTS

204 patients underwent an antegrade access procedure (150 appendicostomies and 54 cecostomies). Skin-level leakage (3% vs. 22%) and wound infections (7% vs. 28%) occurred less frequently in patients with appendicostomy compared to cecostomy. Nineteen (13%) appendicostomies required revision for stenosis, 4 (3%) for mucosal prolapse, and 1 (1%) for leakage. The rates of stenosis (33 vs. 12%) and wound infection (13 vs. 6%) were higher in patients who received a neoappendicostomy compared to an in situ appendicostomy. Intervention was needed in 19 (35%) cecostomy patients, 15 (28%) for an inability to flush or a dislodged tube, and 5 for major complications including intraperitoneal spillage in 4 (7%) and 1 (2%) for a tube misplaced in the ileum, all occurring in patients with a percutaneously placed cecostomy. One appendicostomy (1%) patient required laparoscopic revision after the appendicostomy detached from the skin.

CONCLUSION

Patients had a lower rate of minor and major complications after appendicostomy compared to cecostomy. The unique complication profile of each technique should be considered for patients needing these procedures as an adjunct to their care for constipation or fecal incontinence.

TYPE OF STUDY

Retrospective comparative study.

LEVEL OF EVIDENCE

Level III.

Malone antegrade continence enema: Is cecal imbrication essential?

INTRODUCTION

The Malone antegrade continence enema (MACE) procedure is effective in management of fecal incontinence and intractable constipation. Stomal incontinence and stenosis are the most common issues reported, and a recent large study of imbricated MACE procedures reports a surgical revision rate of 17%. The laparoscopic approach is now widely used and precludes imbrication. To date, few studies have reported revision rates in these patients who have undergone non-imbricated MACE creation.

OBJECTIVE

Our goal was to report the long-term outcomes of our non-imbricated patients focusing on complication rates and need for revision.

STUDY DESIGN

Records of patients younger than 18 years of age who underwent non-imbricated MACE between January 2000 and March 2016 at our institution were reviewed. Patients with less than 2 years of follow-up or non-compliance with MACE usage were excluded from analysis. Patient age, ambulatory status, surgical technique, stomal site, and complications including stomal leakage, stomal stenosis, and need for revision were evaluated. Stomal leakage was classified based on our previously reported system.

RESULTS

A total of 81 patients met inclusion criteria. Mean age at time of surgery was 8.4 years. Mean and median follow-up were 6.7 and 6.7 years, respectively. Overall revision rate, for stenosis or incontinence, was 16% with a mean time to any revision of 2.1 years (range 28 days to 7.8 years). Four patients required revision for stomal incontinence while others improved spontaneously without intervention. At the last follow-up, stomal leakage was grade 0 in 93.8% of patients, grade 2 in 2.4%, and grade 3a in 3.7% (summary Table). Stomal stenosis was noted in 11 patients, eight of whom required revision.

DISCUSSION

Our study is limited by its retrospective nature with some component of recall bias. A single surgeon experience is also not representative of others' experiences. However, our results indicate that incontinence improves spontaneously in a majority of patients without need for revision in this non-imbricated cohort.

CONCLUSIONS

Our series shows a similar long-term revision rate in line with that reported in the literature. While imbrication is still recommended during open surgery when the anatomy is suitable, equitable success without imbrication supports the laparoscopic approach and a more liberal approach during open surgery if the anatomy does not permit imbrication.

Long-term outcomes of a Malone antegrade continence enema (MACE) for the treatment of fecal incontinence or constipation in adults

PURPOSE

The aim of the study was to assess the long-term outcome of a Malone antegrade continence enema (MACE) procedure for fecal incontinence or constipation in adults.

METHODS

This retrospective single-center study assessed the long-term outcome and quality of life (QoL) of patients who underwent a MACE procedure between 2005 and 2014 at the Maastricht University Medical Centre. Success rate was quantified by using Malone's continence scale. Quality of life was assessed by validated questionnaires covering general quality of life (SF-36 and Karnofsky scale), current pain level (visual analog scale), fecal incontinence (Vaizey incontinence survey), or constipation (Cleveland Clinic Constipation Score).

RESULTS

Based on patients' records, 22 out of 30 patients (73%; 95% CI 54-87%) were still using their MACE. Mean follow-up was 43 months (SD 25.9) since time of surgery. According to the Malone continence scale, the overall success rate was 37% (95% CI 20.0-53.3). Nine patients developed a postoperative complication. Eighteen out of 22 patients (13 with constipation and 5 with fecal incontinence) returned the QoL questionnaires (82% response rate). Long-term quality of life of patients with a MACE did not differ from the general Dutch population.

CONCLUSIONS

In our cohort of patients with fecal incontinence or constipation, MACE resulted in a disappointed overall success rate of 37%. However, it may be indicated in patients who do not prefer more invasive surgical procedures or a definite stoma. The success and morbidity rate should be thoroughly discussed with the patients preoperatively.

No Appendix is Too Short-Simultaneous Mitrofanoff Catheterizable Vesicostomy and Malone Antegrade Continence Enema (MACE) for Children with Spina Bifida

OBJECTIVE

To present the results of simultaneous creation of both Mitrofanoff stoma and Malone antegrade continence stoma (MACE) using simple division of the appendix and a cecal extension method.

MATERIALS AND METHODS

Between June 2011 and November 2016, simultaneous Mitrofanoff and MACE was performed in 16 children (12 children-simple division of the appendix, 4 children-appendicovesicostomy and cecal extension of the appendix). Extension of the appendix was achieved by tubularization of the excised cecal flap next to the short appendicular stump. The new extended channel was then wrapped by cecal wall.

RESULTS

Follow-up was 40 months (10-74 months). Currently, in all children, both stomas are easily catheterizable. Obstruction of MACE occurred in 5 children (4 with split appendix, 1 with extended appendix); Mitrofanoff stomal stenosis occurred in 1 child. Endoscopic revision and prolonged catheterization of stenotic stomas were effective in all cases. Wound infection and dehiscence was noted in 2 children (both with split appendix). Drainage and intravenous antibiotics were effective. All Mitrofanoffs are continent. In 4 children there is incident minor leakage of the MACE (3 with split appendix and in 1 with extended appendix).

CONCLUSION

The split appendix procedure is feasible. Cecal extension of the appendix seems to be a good option when the appendix is too short for a simple split procedure.

Laparoscopic Appendicostomy Low-Profile Balloon Button for Antegrade Enemas in Children

INTRODUCTION

The Malone appendicostomy is a continent channel used for antegrade enemas. It requires daily cannulation and is susceptible to stenosis. We use an indwelling low-profile balloon button tube inserted through the appendix into the cecum for antegrade enemas. We hypothesized that this method is effective at managing constipation or fecal incontinence and is associated with a low rate of stenosis.

METHODS

Children who underwent laparoscopic appendicostomy balloon button placement at our institution from January 2011 to April 2017 were identified. The primary outcome was success in managing constipation or fecal continence as measured by the Malone continence scale. Postoperative complications were analyzed.

RESULTS

Thirty-six children underwent the procedure, 35 of which met the inclusion criteria. Thirty-one patients (88.5%) underwent the operation for idiopathic constipation, 3 patients (8.6%) for anorectal malformation, and 1 patient (2.9%) for hypermobility. Rate of open conversion was 3%. A full response was obtained in 24 patients (68.6%), partial response in 9 patients (25.7%), and 2 patients failed (5.7%). One patient developed an internal hernia requiring laparotomy and later developed mucosal prolapse. One patient developed a stricture noted at button change. Seven patients (20%) underwent reversal of their appendicostomy tube: 5 due to return of normal bowel function and 2 due to discomfort with flushes.

CONCLUSION

A laparoscopic appendicostomy with a balloon button tube is an effective means of addressing chronic constipation or fecal incontinence. The stenosis rate associated with tube appendicostomy may be lower than those reported for Malone antegrade continence enema procedures.

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

INTRODUCTION

The Malone antegrade continence enema (MACE) procedure remains an effective tool in providing independence to patients with refractory constipation. Appendiceal, ileal and colonic segments are all used depending upon the patient's individual anatomy and surgeon's preference. Unfortunately, MACE stomal stenosis (SS) remains a frustrating complication. It was hypothesized that SS is associated with the type of efferent limb used for MACE construction.

OBJECTIVE

To perform a retrospective risk analysis of the pre-operative factors that correlated with postoperative stomal stenosis.

MATERIALS AND METHODS

The study reviewed 39 consecutive patients treated with MACE by a single surgeon at the present institution. Collected data included: the type of channel construction, stoma site, pre-operative body mass index (BMI) z-score, pre-operative diagnosis, and development of SS. Stomal stenosis was defined as a documented inability to catheterize, requirement of a Chait tube, or a subsequent stomal revision. An odds ratio (OR) analysis was performed to evaluate the association with the development of SS.

RESULTS

Stomal stenosis developed in 19 patients (49%) with an average follow-up of 4.7 years. The majority of patients had a diagnosis of myelomeningocele (90%), and there was no significant difference in gender distribution (54% males, 46% females). The distribution types of MACE efferent limbs consisted of appendicocecostomy in 20 (51%), cecal-wall flap in 16 (41%) and ileocecostomy in three patients (8%). Neither type of efferent limb, nor stomal location were significant predictors of postoperative SS. Pre-operative obesity (BMI ≥95%), however, demonstrated a significant risk of SS compared to non-obese patients (OR 4.44, 95% CI 1.08-18.4, P = 0.04).

DISCUSSION

This was a single-institution study of a relatively small number of patients. However, examining consecutive patients with a common surgeon can minimize technique variability. Also, the rates of stenosis in this cohort were higher than most. This may have been due to a more broad definition (unable to catheterize). These findings complement recent literature showing an increased complication rate for the obese pediatric patient.

CONCLUSION

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.

Outcomes and satisfaction in pediatric patients with Chait cecostomy tubes

INTRODUCTION

Patients with spina bifida and other spinal dysraphisms commonly suffer from fecal incontinence and constipation, which can be treated with antegrade continence enemas. Currently, information regarding outcomes and satisfaction in children who have Chait cecostomy tubes is lacking. The aim of our study was to evaluate the effectiveness of Chait cecostomy tubes in management of constipation in children with spinal dysraphisms.

MATERIALS AND METHODS

A questionnaire was completed by patients and/or their families during office visits at the University of Iowa or Nationwide Children's Hospital during follow-up pediatric urology office visits. Two study groups completed the questionnaires: 1) Patients with neurogenic bowels who had a cecostomy tube in place (CT) and 2) patients with neurogenic bowels with no cecostomy tube (NCT). The survey used Likert scaled and nonrated questions to assess demographics, bowel continence, and satisfaction.

RESULTS

A total of 86 patients completed the questionnaire: 53 CT patients and 33 NCT patients. CT patients rated the effectiveness of their cecostomy tube in managing their constipation significantly higher than the NCT group rated the effectiveness of their conventional bowel management methods (p < 0.001). Within the CT group, 48% of patients had complete or near complete continence, 40% had partial fecal incontinence, while only 12% remained incontinent. Of the CT respondents, 88% were overall satisfied with the cecostomy tube (Figure) and 92% would have the cecostomy tube placed again. In addition, hygiene, independence, and social confidence were significantly improved compared with baseline. Complications associated with the Chait tube included granulation tissue that required treatment (60%) and pain with irrigation (24%).

CONCLUSIONS

CT patients reported significantly improved constipation management, fecal continence, and improved quality of life compared with NCT patients. Our pilot study demonstrates that the Chait cecostomy tube is a well-tolerated, effective means for treating constipation and achieving fecal continence with minimal side effects in patients with neurogenic bowels.

Managing fecal incontinence in patients with myelomeningocele in Sub-Saharan Africa: Role of antegrade continence enema (ACE)

BACKGROUND

Neural tube defects (NTDs) are among the major causes of sphincter dysfunctions. Fecal incontinence (FI) because of myelomeningocele (MMC) leads to problems with social acceptability and decreased quality of life (QOL), life satisfaction in addition to other morbidities. This is a report of experience with antegrade continence enema (ACE) in the management of FI in patients with MMC in an African set-up.

MATERIALS AND METHOD

A retrospective review of 23 children and young adults with FI because of MMC managed with ACE from October 2008 to September 2015 from African Specialist Hospital. The clinical outcomes have been analyzed.

RESULTS

From October 2008 to September 2015, a total of thirty-two n=32 patients underwent ACE procedure after repair of MMC associated with FI. Available data of 23 (71.87%) patients were reviewed retrospectively. Mean age at which ACE was created was 6.43±3.83years, range (3.5-17.8) years, median 5years. Follow-up after ACE creation was (0.5-6.9) years, median 2.6years. There were full continence in 13 (56.52%), partial continence in 8 (34.78%) and failure in 2 (8.69%). There were 16 (69.56%) complications and 4 (17.39%) minor post ACE surgery revisions. Mean PedQOL⁽™⁾ score before ACE and then 5, 10, and 15months after ACE were 47.86±13.83, range (20.4-66.0) vs 88.34±7.11, range (77.9-98.6); p=0.000, 88.9±6.44 range (76.9-98.5); p=0.000, 89.01±6.50, range (76.9-98.88) p=0.000 respectively. Mean parental/caregiver satisfaction score for 15 (65.21%) patients aged 6years and below using modified visual analogue scale (VAS) 1 to 10 before ACE and after were 3.06±0.79, range (2-4), median 3 vs 8.0±1.30, range (5-10), median 8; (p=0.000) while 8 (34.78%) patients aged above 6years were able to assess their satisfactions score before and after ACE creation with mean of 1.75±0.70, range (1-3), median 2 vs 7.75±1.03, range (6-9) median 8; (p=0.000).

CONCLUSION

ACE has satisfactory outcomes in an African set-up in patients with MMC associated with FI. Multidisciplinary approach to neurogenic FI should be encouraged in such set-ups.

Ambulatory patients with spina bifida are 50% more likely to be fecally continent than non-ambulatory patients, particularly after a MACE procedure

INTRODUCTION

While fecal incontinence (FI) affects many patients with spina bifida (SB), it is unclear if it is associated with ambulatory status.

OBJECTIVE

To determine if ambulatory status is associated with FI, and a potential confounding variable, in patients with and without a Malone antegrade continence enema (MACE).

STUDY DESIGN

This study retrospectively reviewed of patients aged ≥8 years with SB who were enrolled in an international quality of life study at outpatient visits (January 2013 to September 2015). Patients reported FI over the last 4 weeks (strict criteria: any FI/accidents vs no FI). Patients unable to self-report FI due to developmental delay were excluded. Those who were ambulating outdoors with/without braces/crutches were considered community ambulators. Non-parametric tests and logistic regression were used for analysis.

RESULTS

A total of 115 patients with a MACE and 57 without a MACE were similar in gender (P = 0.99), ventriculoperitoneal status (P = 0.15) and age (16.0 vs 15.4 years, P = 0.11). Median ages at MACE procedure and follow-up were 7.0 and 8.2 years, respectively, and all used the MACE ≥3x/week. They were less likely to be ambulators (54.8 vs 71.9%, P = 0.03). In patients with a MACE, 64 (55.7%) had total fecal continence, compared with 29 (50.9%) without a MACE (P = 0.62). In the MACE group, ambulators were more likely to be continent compared with non-ambulatory patients (65.1 vs 44.2%, P = 0.04) (Table). Although not statistically significant, a similar difference was observed in the non-MACE group (56.1 vs 37.5%, P = 0.25). In the MACE group, continent and incontinent patients, regardless of ambulatory status, had similar rates of MACE use, additive use and time for MACE completion (P ≥ 0.43). MACE ambulators were more likely to be continent than MACE non-ambulators on multivariate analysis (OR 3.26, P = 0.01).

DISCUSSION

This study reported higher than typical FI rates since: (1) it used a stringent definition of total fecal continence; (2) patients without FI were perhaps less likely to participate; and (3) it relied on patient-reported rather than clinician-reported outcomes. This cross-sectional study should not be interpreted as "MACE procedure is ineffective;" this would require a longitudinal study. The present findings may not apply to young children or those with significant developmental delay (patients excluded from the study).

CONCLUSIONS

Ambulatory patients with SB are 50% more likely to have total fecal continence on long-term follow-up, particularly after a MACE procedure. Ambulatory status is a significant confounder of FI and should be considered in future analyses.

All Incontinence is Not Created Equal: Impact of Urinary and Fecal Incontinence on Quality of Life in Adults with Spina Bifida

PURPOSE

We previously reported that the self-reported amount of urinary incontinence is the main predictor of lower health related quality of life in adults with spina bifida. In this study we sought to determine the impact of fecal incontinence on health related quality of life after correcting for urinary incontinence.

MATERIALS AND METHODS

An international sample of adults with spina bifida was surveyed online in 2013 to 2014. We evaluated fecal incontinence in the last 4 weeks using clean intervals (less than 1 day, 1 to 6 days, 1 week or longer, or no fecal incontinence), amount (a lot, medium, a little or none), number of protective undergarments worn daily and similar variables for urinary incontinence. Validated instruments were used, including QUALAS-A (Quality of Life Assessment in Spina bifida for Adults) for spina bifida specific health related quality of life and the generic WHOQOL-BREF (WHO Quality of Life, short form). Linear regression was used (all outcomes 0 to 100).

RESULTS

Mean age of the 518 participants was 32 years and 33.0% were male. Overall, 55.4% of participants had fecal incontinence, 76.3% had urinary incontinence and 46.9% had both types. On multivariate analysis fecal incontinence was associated with lower bowel and bladder health related quality of life across all amounts (-16.2 for a lot, -20.9 for medium and -18.5 for little vs none, p <0.0001) but clean intervals were not significant (-4.0 to -3.4, p ≥0.18). Conversely, health related quality of life was lower with increased amounts of urinary incontinence (-27.6 for a lot, -18.3 for medium and -13.4 for little vs none, p <0.0001). Dry intervals less than 4 hours were not associated with lower health related quality of life (-4.6, p = 0.053) but the use of undergarments was associated with it (-7.5 to -7.4, p ≤0.01). Fecal incontinence and urinary incontinence were associated with lower WHOQOL-BREF scores.

CONCLUSIONS

Fecal incontinence and urinary incontinence are independent predictors of lower health related quality of life in adults with spina bifida. Health related quality of life is lower with an increasing amount of urinary incontinence. Fecal incontinence has a more uniform impact on health related quality of life regardless of frequency or amount.

Fecal Incontinence: Etiology, Diagnosis, and Management

INTRODUCTION

Fecal incontinence is a debilitating condition affecting primarily the elderly. Many patients suffer in silence resulting in both underdiagnosis and undertreatment often culminating in an overall poor quality of life.

METHODS

We sought to review the etiology, diagnosis, and treatment of fecal incontinence based on current literature. Additionally, newer treatment methods such as Solesta will be evaluated.

RESULTS

There are many diagnostic modalities available to assess the degree and severity of the patient's incontinence; however, a thorough history and physical exam is critical. Initial attempts at treatment focus on medical management primarily through stool texture modification with the aid of bulking agents. Failure of medical therapy is often followed by a graded increase in the complexity and invasiveness of the available treatment options. The selection of the most appropriate surgical option, such as overlapping sphincteroplasty and neuromodulation, is multifactorial involving both surgeon and patient-related factors. Neuromodulation has received increased attention in the last decade due to its documented therapeutic success, and newer office-based procedures, such as the Solesta injection, are showing promising results in properly selected patients. Finally, diversion remains an option for select patients who have failed all other therapies.

CONCLUSION

The etiology of fecal incontinence is multifactorial, involving a complex interplay between stool consistency and anatomic integrity. The diagnosis and treatment of fecal incontinence continue to evolve and are showing promising results.

Antegrade continence enema (ACE): predictors of outcome in 111 patients

PURPOSE

The antegrade continence enema (ACE) is used as a means of managing faecal incontinence and constipation with varying outcomes. We aim to evaluate our outcomes of ACEs and identify predictors of outcome.

METHODS

A retrospective case-note review of patients ≤16 years of age undergoing an ACE (March 2000-September 2013) was carried out. Data collected included: patient demographics, functional outcomes and complications. Data are quoted as median (range) and compared using Mann-Whitney and Fisher's exact test. Univariate analysis was performed to identify predictors of successful outcomes. P < 0.05 is significant. Successful outcome = total continence/occasional leakage and failed outcome = regular soiling and/or constipation.

RESULTS

111 patients with complete data sets underwent an ACE [59% male, median age = 9.5 years (3.4-16 years)] and median follow-up = 48 months (4 months-11 years 4 months). Underlying diagnoses were idiopathic constipation (n = 68), anorectal malformation (n = 27), neuropathic bowel (n = 7), Hirschsprung disease (n = 5) and gastrointestinal dysmotility (n = 4). Social continence was achieved in 87/111 (78%). Fifteen percent of patients underwent reversal of ACE due to resolution of symptoms. There was no difference in outcomes related to diagnosis, gender, age or follow-up duration. Complication rate was 20.7% (23/111).

CONCLUSIONS

The ACE is safe and effective in the management of intractable constipation and soiling. No predictors of outcome were identified.

Use of Peristeen® transanal colonic irrigation for bowel management in children: a single-center experience

AIMS

Transanal colonic irrigation has been shown to be effective in bowel management program in adults. However, there exist limited data in children. We appraised the effectiveness of this technique in a series of children with incontinence or constipation and overflow soiling.

METHODS

Following ethical approval, a review of children with incontinence or constipation on a bowel management program with Peristeen® transanal colonic irrigation treated between 2007 and 2012 was performed. Irrigations were performed with a volume of 10-20 ml/kg of water with schedules depending on patient response. Data are reported as median (range).

RESULTS

Twenty-three patients were reviewed. Median age at commencement of irrigations was 7 (2-15) years. Median follow-up is 2 (0.7-3.4) years. Diagnoses include the following: spina bifida (n=11), anorectal anomaly (n=6), Hirschsprung's (n=1), and other complex anomalies (n=5). Sixteen (70%) patients had associated anomalies. Twelve (52%) had constipation and overflow soiling, and 11 (48%) had fecal incontinence. Twenty (87%) had associated urinary wetting. Sixteen (70%) children used alternate-day irrigations, 4 (17%) daily irrigations, and 3 (13%) every third-day irrigations. Nine (39%) patients were taking oral laxatives. Sixteen (70%) reported to be clean and 3 (13%) reported a significant improvement, although were having occasional soiling. Four patients (17%) did not tolerate the irrigations and underwent subsequent colostomy formation for intractable soiling.

CONCLUSIONS

In our experience, Peristeen® transanal colonic irrigation is an effective method of managing patients with focal soiling in childhood. Majority (83%) of children achieve social fecal continence or a significant improvement with occasional soiling. This was accompanied by high parental satisfaction. Peristeen® transanal colonic irrigation is a valid alternative to invasive surgical procedures and should be considered the first line of treatment for bowel management in children with soiling where simple pharmacological maneuvers failed to be effective.

Surgical approaches to fecal incontinence in the adult

Surgical treatment of anal incontinence is indicated only for patients who have failed medical treatment. Sphincterorraphy is suitable in case of external sphincter rupture. In the last decade, sacral nerve stimulation has proven to be a scientifically validated solution when no sphincter lesion has been identified and more recently has also been proposed as an alternative in cases of limited sphincter defect. Anal reconstruction using artificial sphincters is still under evaluation in the literature, while indications for dynamic graciloplasty are decreasing due to its complexity and high morbidity. Less risky techniques involving intra-sphincteric injections are being developed, with encouraging preliminary results that need to be confirmed especially in the medium- and long-term. Antegrade colonic enemas instilled via cecostomy (Malone) can be an alternative to permanent stoma in patients who are well instructed in the techniques of colonic lavage. Stomal diversion is a solution of last resort.

Current management of fecal incontinence: Choosing amongst treatment options to optimize outcomes

The severity of fecal incontinence widely varies and can have dramatic devastating impacts on a person’s life. Fecal incontinence is common, though it is often under-reported by patients. In addition to standard treatment options, new treatments have been developed during the past decade to attempt to effectively treat fecal incontinence with minimal morbidity. Non-operative treatments include dietary modifications, medications, and biofeedback therapy. Currently used surgical treatments include repair (sphincteroplasty), stimulation (sacral nerve stimulation or posterior tibial nerve stimulation), replacement (artificial bowel sphincter or muscle transposition) and diversion (stoma formation). Newer augmentation treatments such as radiofrequency energy delivery and injectable materials, are minimally invasive tools that may be good options before proceeding to surgery in some patients with mild fecal incontinence. In general, more invasive surgical treatments are now reserved for moderate to severe fecal incontinence. Functional and quality of life related outcomes, as well as potential complications of the treatment must be considered and the treatment of fecal incontinence must be individualized to the patient. General indications, techniques, and outcomes profiles for the various treatments of fecal incontinence are discussed in detail. Choosing the most effective treatment for the individual patient is essential to achieve optimal outcomes in the treatment of fecal incontinence.

Satisfaction after the Malone antegrade continence enema procedure in patients with spina bifida

STUDY DESIGN

Retrospective chart review.

OBJECTIVE

To evaluate the clinical outcomes and factors influencing patient satisfaction with Malone antegrade continence enema (MACE) in patients with spina bifida.

SETTING

Japan.

METHODS

We performed retrospective analysis of 21 patients with spina bifida who underwent surgical creation of an MACE stoma. Clinical outcomes were evaluated by medical records, operative notes and mailed questionnaires. Patient satisfaction scores (SSs) were measured on a modified visual analog scale (VAS) from 1 to 10, and the factors influencing the SS were analyzed.

RESULTS

A 100% return rate for the mailed questionnaires was achieved. All patients underwent in situ appendicocecostomy with cecal plication. There was only one complication that required surgical revision. Regarding fecal continence, the overall success rate was 90%. Although 4 patients (19%) had severe irrigation pain and 4 patients (19%) found the washout time intolerably long, 18 (85%) of them were satisfied with the MACE procedure. Age at operation, experience of retrograde colonic enema (RCE), experience of stomal leakage, increased comfort at school or workplace and increased comfort at sleepovers significantly influenced SSs.

CONCLUSION

MACE is a valuable option in achieving fecal continence in patients with spina bifida, with most patients being satisfied with the procedure. In our analysis, younger age at operation, previous experience of RCE, no stomal leakage and improvement of quality of life (enhanced comfort at school, workplace and sleepovers) significantly influenced the high satisfaction after MACE.

Outcome of antegrade continent enema (ACE) procedures in children and young adults

OBJECTIVE

Intractable incontinence affects a large number of children and young adults in the US. The goal of this study is to evaluate the long-term outcomes of surgical access for administration of antegrade continence enemas (ACE) in affected children and young adults.

METHODS

Patients who underwent surgical procedure to enable administration of ACE from 1994 to 2011 were retrospectively reviewed. Data collected included patient demographics, primary diagnosis, surgical technique, conduit used, complications, follow-up duration, and social continence.

RESULTS

Sixty eighty patients underwent surgery to enable ACE; mean follow up was 61 months. Enteral conduit (EC) was performed in 19 patients, tube cecostomy catheters (CC) in 49. Meningomyelocele was diagnosed in 60% of patients. Mean age was 11 (1.67-53) years. Complications included tube dislodgement (43%), granulation tissue (46%), site infection (13%), leakage (32%), break in the tube (6%) and tract stenosis (6%). Complete social continence was achieved in 68%, partial continence was achieved in 29%, and no benefit was achieved in 3% of patients. The rate of complications and incontinence resolution following CC was 78% and 66%, and following EC 89% and 74%. The differences were not statistically significant. CC patients developed granulation tissue more frequently (53%) and leaks of fecal material less frequently (20%) compared to EC patients (26% and 53%) (p < 0.05 and < 0.01). Although children 7 years or younger developed more overall complications (94%) than older patients (69%; p < 0.05), there was not a significant difference in the frequency of any one complication or in the rate of continence, between the two groups. Multivariate analysis showed that EC is three times more likely to be complicated by fecal leakage. CC patients are at greater risk to develop granulation tissue (p < 0.05).

CONCLUSIONS

Most patients achieved social continence and improved hygiene with the aid of ACE. Younger children also benefited greatly from institution of ACE. CC was associated with fewer major complications such as leak of fecal contents than EC but required regular tube changes.

Outcomes following Malone antegrade continence enema and their surgical revisions

BACKGROUND/PURPOSE

The Malone antegrade continence enema (MACE) channel is an effective means to manage patients with neurogenic bowel; however, complications may occur that may require surgical revision. Specific reports of the outcomes of these interventions are limited. We describe our clinical results following revision of MACE.

METHODS

We retrospectively identified patients undergoing MACE revision for at our institution between 1997 and 2009. Type of MACE (in situ appendicocecostomy (AC = 247), ileocecostomy (IC = 25), cecal flap (CF = 10)) performed was recorded, time from creation to revision, site of revision, and need for repeat surgical revision were recorded.

RESULTS

Of a total of 282 patients that underwent creation of MACE during the study period, 49 patients (17%) required surgical revision. Of these 49 patients, 42 had undergone AC, four had IC and three had CF. Mean time from MACE creation to revision was 19 months. Sixty-eight revision procedures were performed in the 49 patients. Skin level or endoscopic procedures accounted for 52/67 (78%) procedures. Sixteen patients (33%) required more than one revision and three patients (6%) required more than two procedures.

CONCLUSIONS

Skin level revisions accounted for over three-fourths of MACE revisions. In our series, two thirds of patients requiring revision required only a single procedure, but one third required more than one revision.

Management of pediatric patients with refractory constipation who fail cecostomy

BACKGROUND

Antegrade continence enema (ACE) is a recognized therapeutic option in the management of pediatric refractory constipation. Data on the long-term outcome of patients who fail to improve after an ACE-procedure are lacking.

PURPOSE

To describe the rate of ACE bowel management failure in pediatric refractory constipation, and the management and long term outcome of these patients.

METHODS

Retrospective analysis of a cohort of patients that underwent ACE-procedure and had at least 3-year-follow-up. Detailed analysis of subsequent treatment and outcome of those patients with a poor functional outcome was performed.

RESULTS

76 patients were included. 12 (16%) failed successful bowel management after ACE requiring additional intervention. Mean follow-up was 66.3 (range 35-95 months) after ACE-procedure. Colonic motility studies demonstrated colonic neuropathy in 7 patients (58%); abnormal motility in 4 patients (33%), and abnormal left-sided colonic motility in 1 patient (9%). All 12 patients were ultimately treated surgically. Nine patients (75%) had marked clinical improvement, whereas 3 patients (25%) continued to have poor function issues at long term follow-up.

CONCLUSIONS

Colonic resection, either segmental or total, led to improvement or resolution of symptoms in the majority of patients who failed cecostomy. However, this is a complex and heterogeneous group and some patients will have continued issues.

Review of organic causes of fecal incontinence in children: evaluation and treatment

Even though fecal incontinence (FI) in children is most commonly the result of functional constipation, there are organic conditions that can be associated with incontinence. FI has a major impact on the quality of life of those children who experience it. The general objectives of any bowel program are to achieve predictability and independence. This is achieved by manipulating colonic transit and stool consistency and by producing more controlled evacuations, usually with the use of rectal interventions. Dietary interventions and medications can be used to change stool consistency or to manipulate transit by accelerating or slowing it down. Biofeedback or other interventions that increase sphincter pressure can also be used to improve anorectal function. Enemas or suppositories can be used to empty the sigmoid colon in a more controlled manner. With the recent advent of the antegrade colonic enemas, the patient can have predictable bowel movements and become independent.

Quality of life in pediatric patients with unremitting constipation pre and post Malone Antegrade Continence Enema (MACE) procedure

OBJECTIVE

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.

METHODS

Patients, ages 5 to 18 years 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, 6 months, and 12 months after the procedure.

RESULTS

A total of 15 consecutive patients meeting protocol criteria were recruited within a period of 20 months. The mean age at the MACE procedure was 9.8 years (range 7.0-11.1). 5 patients were female. The mean QOL score pre-MACE was 64.1. At 6 months post-MACE the mean overall QOL score was 90.2, and it was 92.0 at 12 months. All 15 patients at the 6 month follow up had significant improvement in their QOL (p=1.9 × 10(-7)) and all subcategories of QOL were significantly improved as well.

CONCLUSIONS

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.

The distal left Malone antegrade continence enema--is it better?

PURPOSE

The Malone antegrade continence enema is used for refractory fecal dysfunction in the pediatric neuropathic population. While various locations along the colon have been described, the optimal site for achieving efficient enemas remains unknown. We reviewed our experience with the Malone antegrade continence enema procedure and investigated functional outcomes and complications associated with proximal and distal locations.

MATERIALS AND METHODS

We performed an institutional review board approved, retrospective chart review of 109 consecutive MACE procedures done by a single surgeon from 2000 to 2012. Preoperative patient characteristics, intraoperative techniques and postoperative outcomes were reviewed and statistical analysis was performed.

RESULTS

Included in analysis were 90 patients treated with a total of 109 MACE procedures. Average age at operation was 13.8 years. Myelomeningocele was the most common diagnosis. Most patients underwent simultaneous urinary reconstruction. Stomal complications were most common (49% of patients). We compared the outcomes of proximal (cecal) MACE in 48 cases and distal (sigmoid colon) MACE in 55. Location did not affect the overall efficiency of fecal continence. Flush time was shorter for distal than for proximal MACE stomas (37.2 vs 61.2 minutes, p <0.001). Of the patients 15 underwent a total of 20 complete MACE revisions, including 12 proximal and 6 distal MACEs. As a channel, appendix was associated with a higher but not statistically significant stomal complication rate compared to colon (42% vs 25%).

CONCLUSIONS

A cecal, transverse or colonic location for MACE results in acceptable outcomes. Distal MACE is associated with significantly shorter flush time and possibly fewer stomal complications. Stomal complications remain a frustrating reality of the MACE procedure.

Experience with glycerin for antegrade continence enema in patients with neurogenic bowel

PURPOSE

Malone antegrade continence enemas are used in the management of neurogenic bowel to attain fecal continence. Several different irrigation solutions have been described but glycerin, an osmotic laxative that promotes peristalsis, has rarely been mentioned or studied. We assessed clinical outcomes in our patients with a Malone antegrade continence enema using glycerin based irrigation.

MATERIALS AND METHODS

We retrospectively reviewed patients with neurogenic bowel who underwent a Malone antegrade continence enema procedure between 1997 and 2011. Glycerin diluted with tap water followed by a tap water flush is our preferred irrigation protocol. Bowel regimen outcomes examined included fecal continence, emptying time, leakage from stoma, enema volume, frequency and independence.

RESULTS

Of the 23 patients with followup greater than 6 months 19 used glycerin based irrigation. Average age at surgery was 8.8 years. Patients using glycerin instilled a median of 30 ml (mean 29) glycerin and 50 ml (131) tap water. Fecal continence rate was 95% and stoma leakage rate was 16%, and only 16% of patients required daily irrigation.

CONCLUSIONS

Glycerin is a viable and effective alternative irrigant for antegrade enemas of neurogenic bowel, with an excellent fecal continence rate. The volume of irrigant needed is typically less than 90 ml, which is much less than in published reports using tap water alone.

Ten-year experience using antegrade enemas in children

OBJECTIVE

To describe a single-center, 10-year experience with the use of antegrade enemas.

STUDY DESIGN

Retrospective analysis of 99 patients treated with antegrade enemas at Nationwide Children's Hospital.

RESULTS

Study subjects (median age 8 years) were followed for a mean time of 46 months (range 2-125 months) after cecostomy placement. Seventy-one patients had the cecostomy placed percutaneously and 28 by surgery. Thirty-five patients had functional constipation and 64 patients an organic disease (spinal abnormalities, cerebral palsy, imperforate anus, Hirschsprung's disease). While using antegrade enemas, 71% became symptom-free, in 20 subjects symptoms improved, in 2 subjects symptoms did not change, and in 7 subjects symptoms worsened. Poor outcome was associated with surgical placement of the cecostomy (P < .001), younger age (P = .02), shorter duration of symptoms (P = .01), history of Hirschsprung's disease (P = .05), cerebral palsy (P = .03), previous abdominal surgery (P = .001), and abnormal colonic manometry (P = .004). In 88%, successful irrigation solution included use of a stimulant laxative, and subjects who used a stimulant did significantly better (P < .001) than subjects who started without a stimulant. In 13 patients, the cecostomy was removed 49.7 months after placement without recurrence of symptoms. Major complications occurred in 12 patients and minor complications in 47.

CONCLUSIONS

Antegrade enemas represent a successful and relatively safe therapeutic option in children with severe defecatory disorders. Prognostic factors are identified.

The Malone antegrade continence enema procedure: the Amsterdam experience

BACKGROUND

The Malone antegrade continence enema (MACE) procedure has been previously described as a safe and effective option for the treatment of children with chronic defecation disorders when maximal medical therapy and conventional treatment have failed.

PURPOSE

To evaluate clinical success, complications, and quality of life of children with chronic defecation disorders with a MACE stoma.

METHODS

A retrospective analysis of 23 patients who underwent the construction of a MACE stoma was performed. Preoperative and postoperative data were evaluated. A specific questionnaire was used to assess patient satisfaction.

RESULTS

A significant increase was found in defecation frequency (1.0 [range, 0-4] pretreatment vs 5.5 [range, 0-28] posttreatment per week; P < .006) and a significant decrease in fecal incontinence frequency (10 [range, 0-14] pretreatment vs 0 [range, 0-14] posttreatment per week; P < .034). Postoperative complications of the MACE procedure were fecal leakage (43%), wound infection (52%), and stomal stenosis (39%). A total of 86% of the patients were satisfied with the results of the Malone stoma (n = 21).

CONCLUSIONS

The MACE procedure is an effective treatment in children with intractable defecation disorders. Postoperative complications are, however, not uncommon. Further refinement of the technique focused to reduce the complication rate is necessary to expand the application of this approach.

The appendix as a conduit for antegrade continence enemas in patients with anorectal malformations: lessons learned from 163 cases treated over 18 years

INTRODUCTION

The antegrade continence enema (ACE) has been shown to be a safe and effective method for managing fecal incontinence in the pediatric population. The purpose of this study was to examine our experience with the ACE procedure using the appendix as a catheterizable conduit in children with anorectal malformations (ARMs).

METHODS

We reviewed the charts of all patients who underwent an ACE procedure using the appendix as a catheterizable conduit between January 1992 and January 2010. Preoperative diagnosis (ARM type), operative details, functional outcomes, and postoperative complications were assessed. Technical modifications over time included selective cecoplication, implementation of the umbilical V-V appendicoplasty technique, and laparoscopy for cecal mobilization.

RESULTS

Mean age was 9.9 ± 0.6 years, and 67% were male. The most common preoperative diagnosis was rectourethral fistula in boys (39%) and persistent cloaca in girls (61%). Forty-five complications occurred in 41 patients with an overall incidence of 25.6% (stricture, 18%; leakage, 6%; prolapse, 4%; intestinal obstruction, 0.6%). The incidence of stomal leakage was lower in patients when a cecoplication was performed (2.9% [4/138] vs 29.4% [5/17]; P < .01), and the incidence of stricture was lower in patients when the umbilical anastomosis was created using the V-V appendicoplasty technique (11% [11/100] vs 30% [18/60]; P < .01). Successful management of incontinence was reported by 96% of all patients.

CONCLUSIONS

The ACE procedure using the umbilical V-V appendicoplasty provides an effective and cosmetically superior means for bowel management in children with ARMs. The rate of late complications is not insignificant however, and preventative strategies should focus on careful operative technique and ensuring compliance with catheterization protocols well past the initial postoperative period.

Objective measurement of quality of life changes after ACE Malone using the FICQOL survey

PURPOSE

There is little objective data demonstrating improved quality of life after a Malone antegrade continence enema (ACE) despite the dramatic subjective improvements seen by physicians and caretakers.

METHODS

We utilized the FICQOL survey, a reliable and valid instrument for measuring the impact of fecal incontinence and constipation on quality of life (FICQOL) of caregivers and children with spina bifida. Between 2002 and 2009, 23 families were evaluated prospectively before and after an ACE procedure. Items on the survey were compared with Wilcoxon rank sum or signed rank test.

RESULTS

After an ACE Malone the mean number of bowel movements (BM) per day decreased along with a decrease in number of accidents per week from 3.9 to 0.3. There was no change in the time committed to bowel care. The percentage of patients taking oral laxatives decreased from 44% to 6%. Both parent and child were less often prevented from leaving the house and the caretakers' bother, anxiety and depression due to bowel care decreased. Although factors regarding the child's social issues and parent's employment improved, the changes were not statistically significant.

CONCLUSIONS

Among patients with spina bifida and fecal incontinence who underwent the ACE procedure at our institution, a significant improvement in fecal incontinence and QOL scores was observed using a validated instrument, FICQOL. Without changing the amount of time necessary for bowel care, the ACE procedure decreases the families' worries and anxieties and allows them to leave home with the confidence that their child will not have leakage of stool.

Long-term follow-up of patients after antegrade continence enema procedure

BACKGROUND

Antegrade continence enema (ACE) has become an important therapeutic modality in the treatment of intractable constipation and fecal incontinence. There are little data available on the long-term performance of the ACE procedure in children.

METHODS

A retrospective review of patients who underwent the ACE procedure was conducted. Irrigation characteristics and complications were noted. Outcome was assessed for individual encounters based on frequency of bowel movements, incontinence, pain, and predictability.

RESULTS

One hundred seventeen patients underwent an ACE. One hundred five patients had at least 6 months of follow-up, and were included in the analysis. Diagnoses included myelodysplasia (39%), functional intractable constipation (26%), anorectal malformations (21%), nonrelaxing internal anal sphincter (7%), cerebral palsy (3%), and other diagnoses (4%). The average follow-up was 68 months (range 7-178 months). At the last follow-up, 69% of patients had successful bowel management. Of the 31% of patients who did not have successful bowel management, 20% were using the ACE despite suboptimal results, 10% required surgical removal, and 2% were not using the ACE because of behavioral opposition to it. Patients were started on normal saline, but were switched to GoLYTELY (PEG-3350 and electrolyte solution) if there was an inadequate response (61% at final encounter). Additives were needed in 34% of patients. The average irrigation dose was 23 ± 0.7 mL/kg. The average toilet sitting time was 51.7 ± 3.5 minutes, with infusions running for 12.1 ± 1.2 minutes. Stomal complications occurred in 63% (infection, leakage, and stenosis) of patients, 33% required surgical revision and 6% eventually required diverting ostomies.

CONCLUSIONS

Long-term use of the ACE gives successful results in 69% of patients, whereas 63% had a stoma-related complication and 33% required surgical revision of the stoma.

Total continence reconstruction using the artificial urinary sphincter and the Malone antegrade continence enema

PURPOSE

Surgical management of children with myelomeningocele addresses 2 aspects of the disease, neurogenic bladder and neurogenic bowel. Results of total continence reconstruction using an artificial urinary sphincter and Malone antegrade continence enema are presented.

MATERIALS AND METHODS

We performed a retrospective chart review of patients who underwent simultaneous artificial urinary sphincter placement and a Malone antegrade continence enema procedure. From 1997 to 2007 a total of 21 patients with myelomeningocele underwent total continence reconstruction using the artificial urinary sphincter. Mean patient age was 10.4 years (range 6 to 22) and mean followup was 4.7 years (range 0.66 to 11.7). Artificial urinary sphincter cuff was placed around the bladder neck. A Malone antegrade continence enema was performed using appendix in 19 patients and cecal based flaps in 2. Two patients underwent concomitant augmentation cystoplasty. Six patients had concomitant Mitrofanoff vesicostomy using split appendix in 4 and Monti tube in 2.

RESULTS

Immediate postoperative complications were observed in 5 patients, including prolonged ileus (2), urinary tract infection (2) and superficial wound dehiscence (1). Seventeen patients (81%) achieved complete urinary continence and 5 were voiding with sphincter cycling. Improvement in urinary continence with dry intervals greater than 3 hours was reported in 2 patients. There were 19 patients (90%) who reported fecal continence, with 2 reporting soiling 1 to 2 times a week. Malone antegrade continence enema stoma stenosis occurred in 3 patients and 2 required revisions. Sixteen patients (76%) achieved complete continence of stool and urine. During followup 2 artificial urinary sphincters were explanted and 8 patients (38%) underwent bladder augmentation.

CONCLUSIONS

Urinary and fecal continence in patients with myelomeningocele is achievable with a single total continence reconstruction procedure using the artificial urinary sphincter and the Malone antegrade continence enema with durable results.

Urologic management of spina bifida

The urologist plays an important role in the multidisciplinary team of physicians who provide care for patients with spina bifida. We review common strategies for managing the urinary tract in these patients. The primary objective in all phases of life is protecting kidney function by minimizing bladder hostility and establishing a good capacity, low-pressure urinary reservoir. Ensuring adequate bladder and bowel continence is also paramount for enhancing self-esteem and independence. Medical therapy incorporating clean intermittent catheterization and antimuscarinic medication is the cornerstone of neurogenic bladder management and often the only intervention required to achieve the above goals. Others may require formal lower urinary tract reconstruction to prevent urinary tract deterioration. As will be shown, current management, while effective, is not supported by strong evidence-based protocols; and the impact of any intervention upon quality of life, while subjectively seen as positive, does not have objective validation. These limitations are recognized and currently the subject of urologic investigation.

The role of the retrograde colonic enema in children with spina bifida: is it inferior to the antegrade continence enema?

OBJECTIVES

The aim of this study was to evaluate the efficacy of the retrograde colonic enema relative to the Malone antegrade continence enema.

METHODS

We retrospectively investigated 25 children with spina bifida and fecal incontinence. Thirteen children had started retrograde colonic enema and twelve had started Malone antegrade continence enema. Fecal continence, water volume, time to washout, procedure frequency, pain during procedure, performance independence and demographical data were compared between the two groups.

RESULTS

Fecal continence was achieved for 10 of 13 (76.9%) in the retrograde group and 9 of 12 (75.0%) in the antegrade group. In the antegrade group 8 of 12 (66.7%) performed procedure independently, while 3 of 13 (23.1%) did so in the retrograde group. Achievement of fecal continence did not differ between the groups, but procedure independence was significantly better in the antegrade group.

CONCLUSIONS

Our results suggest that retrograde colonic enema was not inferior to Malone antegrade continence enema on fecal continence. We recommend considering retrograde colonic enema prior to introduction of Malone antegrade continence enema in children with spina bifida.

The urologist's role in the management of spina bifida: a continuum of care

Caring for the child with spina bifida necessitates lifelong care by a coordinated team of health care providers, and the urologist plays a vital role in this team. The most important management goal of the urologist is the early establishment and consistent maintenance of a lower pressure urinary reservoir. Ensuring social continence along with its attendant social independence provides some of the greatest management challenges. In those patients who fail medical therapy, surgeons, caregivers, and patients must understand the scope of lower urinary tract reconstruction, the need for strict compliance, and the possibility of future surgery. In this article, we review the recent advances in spina bifida management.

After the honeymoon comes divorce: long-term use of the antegrade continence enema procedure

BACKGROUND

Having reported that 18% of children discontinue use of the antegrade continence enema (ACE) after 5 years, we aimed to determine long-term use after an ACE procedure.

METHODS

A postal/telephone questionnaire was conducted. Subjects were consecutive children undergoing an ACE between 1993 and 1999. Outcome measures were use of ACE, reasons for nonuse, complications, and overall satisfaction.

RESULTS

Of 84 eligible subjects, data were available on 61 (73%) aged 22.4 years (15.5-35.1 years). Underlying diagnoses included spina bifida (n = 27), anorectal malformations (n = 18), constipation (n = 11), Hirschsprung's disease (n = 1), sacral agenesis (n = 2), and trauma/tumor (n = 2). Follow-up was 11.02 years (8.34-14.39 years). Thirty-six (59%) of 61 patients were still using their ACE. Reasons for nonuse were lack of effectiveness (n = 14), complications (n = 5), psychologic issues (n = 2), and poor compliance (n = 2). There was no association between diagnosis and nonuse (chi(2), P = .63). In those still using ACE, the overall satisfaction score was 4.1 (1-5). Several individuals reported feeling abandoned on becoming adults and losing the support they had in childhood.

CONCLUSION

There is a late "failure" rate for the ACE procedure. However, satisfaction was high among those still using the ACE. This study further emphasizes the need for robust transitional care arrangements.

Tap water irrigation and additives to optimize success with the Malone antegrade continence enema: the Indiana University algorithm

PURPOSE

We report the long-term effectiveness of standard tap water for Malone antegrade continence enema irrigation as well as our algorithm for managing refractory constipation/fecal incontinence in a large single institution experience.

MATERIALS AND METHODS

We retrospectively reviewed the charts of 256 Malone antegrade continence enema procedures performed for chronic constipation and/or incontinence due to neuropathic bowel. Continence, type of fluid used to irrigate the colon, volume of flushes and the need for additives were recorded and a database was created. All patients were initially treated with tap water irrigation. Those in whom tap water irrigation failed underwent complete bowel cleanout with enemas and GoLYTELY via the Malone antegrade continence enema, followed by a gradual increase in irrigation volume. If this was unsuccessful, additives of mineral oil, MiraLAX or glycerin were added to the irrigant daily.

RESULTS

A total of 236 patients with at least 6 months of followup were included in this study. Mean age at surgery was 10.2 years (range 2 to 36) and mean followup in the entire cohort was 50 months (range 6 to 115). Mean volume of colonic flushes was 642 ml (range 100 to 1,000). Of the patients 196 (83.1%) achieved total fecal continence with tap water flushes alone. Using additives increased the overall continence rate to 93.6% (p <0.0001).

CONCLUSIONS

The Malone antegrade continence enema procedure has proved invaluable for treating children with refractory constipation. When additives are used in conjunction with water flushes, they can significantly improve the overall fecal continence rate in partially continent children.
