The Malone antegrade continence enema procedure in the management of patients with spina bifida

Pediatric Neurogenic Bladder and Bowel Dysfunction: Will My Child Ever Be out of Diapers?

CONTEXT

Managing patient and parent expectations regarding urinary and fecal continence is important with congenital conditions that produce neurogenic bladder and bowel dysfunction. Physicians need to be aware of common treatment algorithms and expected outcomes to best counsel these families.

OBJECTIVE

To systematically evaluate evidence regarding the utilization and success of various modalities in achieving continence, as well as related outcomes, in children with neurogenic bladder and bowel dysfunction.

EVIDENCE ACQUISITION

We performed a systematic review of the literature in PubMed/Medline in August 2019. A total of 114 publications were included in the analysis, including 49 for bladder management and 65 for bowel management.

EVIDENCE SYNTHESIS

Children with neurogenic bladder conditions achieved urinary continence 50% of the time, including 44% of children treated with nonsurgical methods and 64% with surgical interventions. Patients with neurogenic bowel problems achieved fecal continence 75% of the time, including 78% of patients treated with nonsurgical methods and 73% with surgical treatment. Surgical complications and need for revisions were high in both categories.

CONCLUSIONS

Approximately half of children with neurogenic bladder dysfunction will achieve urinary continence and about three-quarters of children with neurogenic bowel dysfunction will become fecally continent. Surgical intervention can be successful in patients refractory to nonsurgical management, but the high complication and revision rates support their use as second-line therapy. This is consistent with guidelines issued by the International Children's Continence Society.

PATIENT SUMMARY

Approximately half of children with neurogenic bladder dysfunction will achieve urinary continence, and about three-quarters of children with neurogenic bowel dysfunction will become fecally continent. Most children can be managed without surgery. Patients who do not achieve continence with nonsurgical methods frequently have success with operative procedures, but complications and requirements for additional procedures must be expected.

Incontinence affects health-related quality of life in children and adolescents with spina bifida

PURPOSE

Despite devoting many resources to managing urinary and fecal incontinence (UI and FI) in children with spina bifida (SB), it remains unclear whether either is associated with lower health-related quality of life (HRQOL). We sought to determine the impact of UI and FI on HRQOL in this population.

MATERIALS AND METHODS

Children with SB (8-17 years) living in the United States were surveyed online and in SB clinics (2013-15). We evaluated incontinence over the previous 4 weeks using a UI dry interval (<4 h, ≥4 h), FI clean interval (<1 week, ≥ 1 week), and self-reported amount of UI and FI (for each: a lot, medium, a little, none). HRQOL was assessed with QUALAS, a validated SB-specific instrument. Linear regression was used.

RESULTS

The mean age of 298 children was 12.5 years (52.0% male). Overall, 73.1% had UI, 52.3% had FI, and 43.6% had both. Adjusting for concurrent UI and FI, any UI was associated with lower HRQOL in 14-17 year olds (p < 0.0001) and 10-13 year olds (p = 0.048), but not 8-9 year olds (p = 0.98) (Figure). All age groups reported lower HRQOL with FI (p ≤ 0.0001). On multivariate analysis, UI and FI incontinence intervals were not associated with lower HRQOL for any age group (p ≥ 0.58 and p ≥ 0.10, respectively). Higher quantities of UI were associated with ever-lower HRQOL, particularly in 14-17 year olds (p ≤ 0.02). Any quantity of FI was associated with lower HRQOL in all ages. The findings did not change significantly on exploratory analysis correcting for demographic and clinical variables.

DISCUSSION

We report the first evidence that incontinence matters to children and adolescents with SB. Being a cross-sectional study, we were unable to track HRQOL over time. A prospective study is required to assess if HRQOL impact of UI indeed changes as a child grows up and if improving incontinence with treatments improves HRQOL. Findings are similar to those reported in adults with SB and suggest that the concept of "social continence" based on time interval has no HRQOL relevance in children, adolescents or adults with SB.

CONCLUSIONS

UI is negatively associated with HRQOL in children with SB in an age-dependent fashion: starting in 10 year olds and increasing until 14 years. FI correlates with lower HRQOL regardless of age. Similar to findings in adults with SB, HRQOL is lower with increasing amounts of UI and not the length of a dry interval. FI impacts HRQOL uniformly, regardless of frequency or amount.

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.

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.

Constipation and Outcomes of Cecostomy

Constipation, defined as delay or difficulty in defecation, present for 2 or more weeks, is a common problem encountered by both primary and specialty medical providers. There are no randomized controlled trials on the use of antegrade enemas in the pediatric population. Most published papers are based on the experience at a particular center. The aim of this article is to describe the pathophysiology of constipation, review the contribution of colonic manometry to the diagnosis of constipation, summarize the advancements in the management of constipation through the use of antegrade enemas, and study the outcomes of cecostomy at different centers. This study is a comprehensive literature review generated by computerized search of literature, supplemented by review of monographs and textbooks in pathology, gastroenterology, and surgery. Literature search was performed using the publications from 1997 to 2012. The search included publications of all types presenting or reviewing data on cecostomy. The antegrade continence enema is a therapeutic option for defecation disorders when maximal conventional therapy is not successful. Symptoms of defecation disorders in children with different underlying etiologies improve significantly after a cecostomy is created. In addition, there is a benefit on the patients' physical activity, healthcare utilization, and general well-being. Based on the review of published literature it seems that antegrade enemas are a successful therapeutic option in children with severe constipation and/or fecal incontinence. With the advent of cecostomy buttons, patient compliance and the overall cosmetic appearance have improved.

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.

The impact of transcutaneous electrical stimulation therapy on appendicostomy operation rates for children with chronic constipation--a single-institution experience

PURPOSE

Appendicostomy for antegrade continence enema is a minimally invasive surgical intervention that has helped many children with chronic constipation. At our institution, since 2006, transcutaneous electrical stimulation (TES) has been trialed to treat slow-transit constipation (STC) in children. This retrospective audit aimed to determine if TES use affected appendicostomy-formation rates and to monitor changes in practice. We hypothesized that appendicostomy rates have decreased for STC but not for other indications.

METHODS

Appendicostomy-formation rate was determined for the 5 years before and after 2006. Children were identified as STC or non-STC from nuclear transit scintigraphy and patient records.

RESULTS

Since 1999, 317 children were diagnosed with STC using nuclear transit scintigraphy with 121 during 2001 to 2005 (24.2/year) and 147 during 2006 to 2010 (29.4/year). Seventy-four children had appendicostomy formation. For 2001 to 2005, appendicostomy-formation rates for STC and non-STC children were similar: 5.4 per year (n = 27) and 4.8 per year (n = 24), respectively. For 2006 to 2010, appendicostomy-formation rates were 1.2 per year (n = 6) for STC and 3.2 per year (n = 16) for non-STC (χ(2), P = .04).

CONCLUSION

Since 2006, appendicostomy-formation rates have significantly reduced in STC but not in non-STC children at our institute, coinciding with the introduction of TES as an alternative treatment for STC. Transcutaneous electrical stimulation has not been tested on non-STC children in this period.

Management goals for the spina bifida neurogenic bladder: a review from infancy to adulthood

Patients with spina bifida require longitudinal urological care as they transition from childhood to adolescence and then to adulthood. Issues important to urological health, such as protection of the upper tracts and prevention of incontinence, need vigilant follow-up throughout the patient's life. As the child ages, additional issues such as sexual functioning also become increasingly important for social integration. Despite this need for regular assessment, many adult patients with spina bifida lose coordinated urological care after leaving specialized pediatric spina bifida clinics. Consequently, urologists frequently encounter an adult patient with spina bifida in practice and they need to understand the basic urological treatment goals and potential complications for this population.

Children with spina bifida: key clinical issues

Spina bifida is the most common of the neural tube defects, which include myelomeningocele, encephalocele, and anencephaly. Spina bifida is a complex and multisystem birth defect, in which one or more vertebral arches may be incomplete. This article discusses the sensory and motor impairments, neurologic disorders, orthopedic and cognitive impairments, and skin and other problems associated with spina bifida. This article also summarizes some of the key clinical issues in the care of children with this complex birth defect.

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 experience of finding an effective bowel management program for children with spina bifida: the parent's perspective

Many families who have a child with spina bifida identify establishing an effective bowel program as one of the major challenges they face; yet, we know little about a family's experience with this process. The purpose of this qualitative study was to describe the parent's experience. Seven parents were interviewed by telephone. Content analysis yielded four themes: (a) long complicated journey, (b) the impact of the journey on the child, (c) the family struggle, and (d) the promise of the future. The major contribution of this study is a compelling description of one of the most difficult areas for these children and their families. A better understanding of this issue enhances the health care providers' ability to deliver optimal health care.

Experimental antegrade enema. Effects on water, electrolyte and acid-base balances with different solutions

PURPOSE

To study the effects on the water, electrolyte, and acid-base balances in rabbits submitted to antegrade enema with different solutions through appendicostomy.

METHODS

Forty male New Zealand rabbits were submitted to appendicostomy, and distributed in 4 groups, according to the antegrade enema solution: PEG group, polyethylene glycol electrolyte solution (n=10); ISS group, isotonic saline solution (n=10); GS group, glycerin solution (n=10); SPS group, sodium phosphate solution (n=10). After being weighed, arterial blood gas analysis, red blood count, creatinine and electrolytes were measured at 4 times: preoperatively (T1); day 6 postop, before enema (T2); 4h after enema (T3); and 24h after T3 (T4).

RESULTS

In PEG group occurred Na retention after 4h, causing alkalemia, sustained for 24h with HCO3 retention. In ISS group occurred isotonic water retention and hyperchloremic acidosis after 4h, which was partially compensated in 24h. GS group showed metabolic acidosis after 4h, compensated in 24h. In SPS group occurred hypernatremic dehydration, metabolic acidosis in 4h, and hypokalemia, hypocalcemia, hypomagnesemia, and metabolic alkalosis with partially compensated dehydration in 24h.

CONCLUSIONS

All solutions used in this study caused minor alterations on water, electrolyte or acid-base balances. The most intense ones were caused by hypertonic sodium phosphate solution (SPS) and isotonic saline solution (ISS) and the least by polyethyleneglycol electrolyte solution (PEG) and glycerin solution 12% (GS).

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.

Impact of cecostomy and antegrade colonic enemas on management of fecal incontinence and constipation: ten years of experience in pediatric population

BACKGROUND

In childhood and adolescence, fecal soiling represents a psychologically devastating problem. Physical and emotional distress associated with daily rectal enemas is minimized by the introduction of a cecostomy tube for colonic cleansing with antegrade colonic enemas (ACEs).

PATIENTS AND METHODS

Over a period of 10 years (1997-2007), we performed "button" cecostomies in 69 pediatric patients with fecal soiling secondary to a variety of disorders; laparoscopic procedures were performed in 40 and open procedures in 29. Mean postoperative follow-up was 4.03 SD +/- 1.76 years. Cleansing protocols differed between patients.

RESULTS

We adopted a standardized questionnaire concerning management of incontinence/intractable constipation before and after button cecostomy insertion to assess the long-term impact of ACE on symptom severity and quality of life. Complications included tube dislodgement (n = 9), development of granulation tissue (n = 11), decubitus ulcer (n = 5), and infection (n = 3). Patient/parents satisfaction (appraisal scale 1-3) and improvement of quality of life achieved statistical significance for both (P < .001).

CONCLUSIONS

Since button cecostomy and ACE were introduced in our institution as a management option, the treatment of fecal incontinence and intractable constipation significantly improved in terms of efficacy and patient compliance and also resulted in greater patient and parent satisfaction.

Long-term functional assessment of antegrade colonic enema for combined incontinence and constipation using a modified Marsh and Kiff technique

PURPOSE

Constipation and fecal incontinence can severely affect quality of life for patients, particularly when simultaneously present. Malone antegrade colonic enema enables periodic colonic emptying, thus preventing uncontrolled passage of feces and constipation.

METHODS

Eleven patients with fecal incontinence and severe constipation or perineal colostomy after Miles' operation underwent a modified Marsh and Kiff ileostomy for antegrade colonic enema. Before and after surgery, the patients were fully evaluated for gastrointestinal functions, including gallbladder and stomach emptying time, H(2)-breath test, colonic transit time, dynamic defecography, and anorectal manometry. The severity of incontinence and constipation was scored preoperatively and postoperatively by using the American Medical System score and Cleveland Clinic Constipation scale, respectively, whereas the quality of life was measured by the Gastrointestinal Quality of Life Index. The surgical technique involved division of the terminal ileum 10 to 15 cm from the ileocecal valve, anastomosis and intussusception of the ileum with the cecum, narrowing of the ileal conduit with a linear stapler, and a small, introflexed ileostomy with an advanced skin flap.

RESULTS

During the postoperative period, the mean American Medical System score decreased significantly from 77 to 11 (P<0.01) and the mean Cleveland Clinic Constipation score from 23 to 8.5 (P<0.01) with a significant improvement of quality of life. Antegrade colonic enema did not affect gallbladder, gastric, or orocecal transit time, which remained comparable with baseline. Colonic scintigraphy showed that antegrade colonic enema was efficient to clean the whole colon and rectum, leaving only 24 (range, 6-40) percent of the initial radioactivity after 30 minutes. Ileal manometry confirmed the presence of a high-pressure zone, preventing accidental reflux.

CONCLUSIONS

Modified Marsh and Kiff technique is a safe and effective surgical option to treat patients with combined fecal incontinence and severe constipation and those with perineal colostomy after Miles. It should be recommended as a last option before colostomy.

Treatment of a leaking ACE conduit with Deflux injections

Faecal leakage from the catheter conduit can be troublesome and reduces the convenience of use of antegrade continence enema (ACE). We report the results of Deflux injection treatment for leaking ACE conduits in nine patients. From 1994 to the end of 2005, 81 patients underwent a procedure for ACE [appendicostomy with wrap (AW) n = 29, appendicostomy straight (AS) n = 44, Monti-Yang ileal tube (MY) n = 5, lateral caecal flap (LCF) n = 1, caecal tube (CT) n = 1, sigmoid tube (ST) n = 1]. Nine (11%) patients (AW n = 3, AS n = 1, MY n = 3, LCF n = 1, ST n = 1) had persistent stomal leak and underwent Deflux injections of the ACE conduit. With the patients in general anaesthesia, the conduit was visualised with CH10.5 cystoscope. At the junction of the conduit and colon, 0.5-1.0 ml of Deflux was injected submucosally at three sites to create intermingling mounds in order to narrow the conduit. After the injections, a balloon catheter was left in the conduit for 3-7 days. When necessary, the injections were repeated. The result was graded as no improvement, moderate improvement, significant improvement. Nine patients underwent a median of 2 (range 1-4) injections. No major complications occurred. The results after a median follow-up of 22 (range 3-53) months from the first injection were as follows: no improvement (n = 1), moderate improvement (n = 5), significant improvement (n = 3). Repeated injection of the ACE conduit with Deflux is a low invasive method and provides moderate to good results in the majority of the patients who suffer from faecal leakage from conduit.

Laparoscopic antegrade continence enema using a two-port technique

BACKGROUND

The antegrade continence enema is an effective method of treatment of fecal incontinence. We report our experience of a laparoscopic antegrade continence enema procedure and describe a simple approach to this procedure using a two-port technique.

MATERIALS AND METHODS

Over a 3-year period, 12 children with intractable constipation and fecal soiling underwent the antegrade continence enema procedure laparoscopically. All cases had full bowel preparation the day before surgery. This procedure was done through one 5-mm camera port and two 5-mm working ports in 8 cases, and using the camera port and only one additional 5-mm working port in 4 cases. The appendix was used in 5 cases and the cecum in 3 cases with the threeport technique while the appendix was used in all 4 cases with the two-port technique. The appendix or cecum was delivered extracorporeally through the 5-mm port site in the right lower quadrant. The mucocutaneous anastomosis was stented using a gastrostomy button.

RESULTS

Between 2001 and 2004, 12 children (10 male, 2 female) underwent a laparoscopic antegrade continence enema procedure at a median age of 10.5 years (range, 7-14 years). This procedure was easy to perform and no case required conversion to an open procedure. The wash-outs via the MIC-KEY gastrostomy button (MIC-KEY, Kimberly-Clark) were commenced at a median of 3.5 days (range, 1-5 days). Median postoperative hospital stay was 2 days (range, 1-5 days). This procedure was effective in completely resolving fecal incontinence in 9 cases and partially resolving it in 3 cases. There were no episodes of stomal stenosis, leakage, or herniation. However, one case required a revision of antegrade continence enema due to wound breakdown and leakage of irrigation fluid around the stoma. The median follow-up period was 15.5 months (range, 5-32 months).

CONCLUSION

The laparoscopic technique is a simple and effective approach in creating an antegrade continence enema. The use of a gastrostomy button can potentially reduce some of the complications commonly associated with an antegrade continence enema. We describe a procedure that incorporates the advantages of both laparoscopy and a button device, which is simple and easy to perform using just two ports.

Colonic manometry as predictor of cecostomy success in children with defecation disorders

PURPOSE

The aim of this study was to define the predictive value of colonic manometry and contrast enema before cecostomy placement in children with defecation disorders.

METHODS

Medical records, contrast enema, and colonic manometry studies were reviewed for 32 children with defecation disorders who underwent cecostomy placement between 1999 and 2004. Diagnoses included idiopathic constipation (n = 13), Hirschsprung's disease (n = 2), cerebral palsy (n = 1), imperforate anus (n = 6), spinal abnormality (n = 6), and anal with spinal abnormality (n = 4). Contrast enemas were evaluated for the presence of anatomic abnormalities and the degree of colonic dilatation. Colonic manometry was considered normal when high-amplitude propagating contractions (HAPC) occurred from proximal to distal colon. Clinical success was defined as normal defecation frequency with no or occasional fecal incontinence.

RESULTS

Colonic manometry was done on 32 and contrast enema on 24 patients before cecostomy. At follow-up, 25 patients (78%) fulfilled the success criteria. Absence of HAPC throughout the colon was related to unsuccessful outcome (P = .03). Colonic response with normal HAPC after bisacodyl administration was predictive of success (P = .03). Presence of colonic dilatation was not associated with colonic dysmotility.

CONCLUSION

Colonic manometry is helpful in predicting the outcome after cecostomy. Patients with generalized colonic dysmotility are less likely to benefit from use of antegrade enemas via cecostomy. Normal colonic response to bisacodyl predicts favorable outcome.

Cecostomy in children with defecation disorders

Administration of antegrade enemas through a cecostomy is a therapeutic option for children with severe defecation disorders. The purpose of this study is to report our 4-year experience with the cecostomy procedure in 31 children with functional constipation (n = 9), Hirschsprung's disease (n = 2), imperforate anus (n = 5), spinal abnormalities (n = 8), and imperforate anus in combination with tethered spinal cord (n = 7). Data regarding complications, antegrade enemas used, symptoms, and quality of life were retrospectively obtained. Placement of cecostomy tubes was successful in 30 of 31 patients. Soiling episodes decreased significantly in children with functional constipation (P = 0.01), imperforate anus (P < 0.01), and spinal abnormalities (P = 0.04). Quality of life improved in patients with functional constipation and imperforate anus. No difference in complications was found between percutaneous and surgical placement. Use of antegrade enemas via cecostomy improved symptoms and quality of life in children with a variety of defecation disorders.

THE COLON FLAP/EXTENSION MALONE ANTEGRADE CONTINENCE ENEMA: AN ALTERNATIVE TO THE MONTI-MALONE ANTEGRADE CONTINENCE ENEMA

PURPOSE

In situations where the appendix is not available for the Malone antegrade continence enema (MACE) procedure a Yang-Monti channel or a colon flap conduit can be created. We report our experience with colonic flap conduits used for the MACE.

MATERIALS AND METHODS

A total of 169 MACE procedures were performed between February 1997 and March 2003. In 11 patients 12 colon flaps or cecal extensions were used to construct the MACE conduit. Diagnoses included myelomeningocele (8 patients), caudal regression (1), sacral agenesis (1) and gunshot wound (1). Mean age at creation of MACE was 11.3 years (range 4.4 to 16.9). Seven cecal flaps, 1 descending colon flap and 4 cecal extension flaps were created.

RESULTS

Average followup was 22.8 months (range 2.6 to 34.6). Indications for colon flap MACE were appendicovesicostomy (6 patients), short appendix (2), shortened mesentery (1), retrocecal appendix (1), prior appendectomy (1) and right hemicolectomy (1). Initially all patients easily catheterized and flushed the MACE once daily. All 11 patients achieved fecal continence. Complications occurred in 3 cases. One obese patient could not visualize the umbilical stoma and it stenosed, requiring conversion to a spiral Monti-MACE. One patient with a cecal extension had development of a false passage, resulting in complete channel stenosis. One patient had development of stomal leakage, which was successfully treated with dextranomer/hyaluronic acid copolymer injection.

CONCLUSIONS

A colon flap MACE conduit is a simple technique to provide access to the colon for irrigation. When faced with situations were the appendix is not available for the MACE procedure the colon flap can be a good option.

Managing faecal incontinence or leakage: the Peristeen Anal Plug

Incontinence can be a devastating problem to many individuals. It is embarrassing and limiting socially, and prevents those with the problem from going about their day-to-day activities. People adopt coping strategies to manage the problem and those with urinary incontinence often look for containment products such as disposable pads or nappy-style products. These products have been developed using different absorbent materials and are accessible to sufferers in local supermarkets. Absorbency of the products has improved so that once wetted, they hold urine more easily. However, the same cannot be said for faecal incontinence management products and there are few that can be called upon to manage this devastating condition. The Peristeen Anal Plug, developed originally as the Conveen Anal Plug, stands alone in the search for a device to manage faecal incontinence or leakage.

IN SITU MALONE ANTEGRADE CONTINENCE ENEMA IN 127 PATIENTS: A 6-YEAR EXPERIENCE

PURPOSE

The initial description of the Malone antegrade continence enema (MACE) relied on a reversed, tunneled and reimplanted appendix. In 1999 we reported our in situ technique that uses windows developed in the appendiceal mesentery for imbrication. We present our long-term results.

MATERIALS AND METHODS

From 1997 to 2003, 168 patients were identified who had undergone a MACE procedure. An in situ technique was performed in 76 females and 51 males. Average patient age at the time of surgery was 9.6 years (range 2.9 to 28.4). Diagnoses included myelomeningocele in 116 cases, lipomeningocele in 6, spinal cord injury in 2, posterior urethral valves in 1, sacral agenesis in 1 and functional constipation in 1.

RESULTS

Cecal plication/imbrication was performed in 100 patients, appendix intussusception and imbrication in 24, and creation of tenia flaps in 3. The abdominal stoma was umbilical in 50 cases, right lower quadrant in 74 and periumbilical in 3. Concomitant genitourinary reconstruction was performed in 87% of patients. Mean followup was 26.9 months (range 0.7 to 68.1). Fecal continence was reported by 91% of the patients. Thirteen stomal revisions (stenosis 10, prolapse 2 and leakage 1) were required in 11 patients. Major complications included a cecal volvulus requiring a right hemicolectomy in 1 patient, small bowel obstruction in 2, and shunt infection and/or malfunction in 2. Four patients have elected to no longer use the MACE for non-technical reasons.

CONCLUSIONS

The in situ MACE procedure has reliable long-term results for treating fecal incontinence associated with neuropathic bowel.

COLONIC TUBES FOR THE ANTEGRADE CONTINENCE ENEMA: COMPARISON OF SURGICAL TECHNIQUE

PURPOSE

The Malone antegrade continence enema has revolutionized the management of intractable fecal incontinence and constipation. When the appendix is absent, surgical options are limited. Small series with short-term followup have demonstrated the feasibility but not the reliability of the continent colonic tube. We present our experience with a lateral based colonic tube. We also compared lateral based colonic tubes to medial based tubes.

MATERIALS AND METHODS

The medical records of patients treated with a continent colonic tube for intractable fecal incontinence were reviewed. We identified 8 patients who underwent the procedure between July 2000 and February 2003. The literature was reviewed to compare lateral vs medial based tubes.

RESULTS

Average followup was 28 months (range 10 to 41). Stomal stenosis developed in 4 patients (50%) within 3 to 6 months of surgery. Passive dilation at the clinic corrected the problem in 3 patients and 1 required operative stomal revision. All 8 patients reported almost complete relief of rectal incontinence and constipation. A literature review demonstrated a significantly higher rate of stomal stenosis in lateral vs medial based colonic tubes (40% vs 12%).

CONCLUSIONS

The continent colonic tube is a safe and effective alternative in patients with refractory fecal incontinence and constipation who do not have an available appendix. These results appear durable during the described period. We believe that this technique is an alternative to the cecostomy button and it should be offered to suitable patients. The lateral based colonic tube appears to have a higher rate of stomal stenosis than medial based colonic tubes, which may be attributed to the local blood supply of the colon.

Cecal volvulus: a report of two cases occurring after the antegrade colonic enema procedure

BACKGROUND

Many children with chronic constipation and fecal incontinence have benefited from the antegrade colonic enema (ACE) procedure. Routine antegrade colonic lavage often allows such children to avoid daytime soiling. This report describes 2 children in whom the ACE procedure was complicated by a cecal volvulus.

METHODS

A retrospective review of 164 children with an ACE procedure was conducted. Two instances of cecal volvulus were identified.

RESULTS

The first child presented with abdominal pain and difficulty intubating the ACE site. Over the subsequent day, his pain worsened, and radiographs depicted a colonic obstruction. At laparotomy, a cecal volvulus resulting in bowel necrosis was observed, and resection of the affected bowel and appendix (in the right lower quadrant) and end ileostomy was required. He subsequently had the stoma closed and a new ACE constructed with a colon flap. The second child presented with shock and evidence of an acute abdomen. At laparotomy, a cecal volvulus was noted, and ileocolic resection including the ACE stoma (located at the umbilicus) and an ileostomy and Hartmann pouch was performed. He had a protracted hospital course requiring ventilator and inotropic support. He currently is well and still has an ileostomy stoma.

CONCLUSIONS

A high index of suspicion for a potentially life-threatening cecal volvulus should be maintained in children undergoing an ACE procedure who present with abdominal pain, evidence of bowel obstruction, or difficulty in advancing the ACE irrigation catheter.

Left-colon antegrade continence enema (LACE) procedure for fecal incontinence

PURPOSE

Antegrade continence enemas (ACE) are an efficacious therapeutic option for patients with fecal incontinence. The authors review their institution's experience with a variation of the Monti-Malone ACE procedure using the left colon as a source of an intestinal conduit and enema reservoir.

METHODS

From 2000 to 2002, 18 patients with fecal incontinence or intractable constipation underwent left-colon ACE (LACE) procedure. Concomitant Mitrofanoff appendicovesicostomy was performed in 15 patients and bladder augmentation in 9. The majority of patients had neural tube defects. A segment of left colon was tubularized, tunneled into the muscular wall of the distal colon, and exteriorized through the left upper quadrant or midabdomen. Stomal catherization and enema installation were started one month postoperatively.

RESULTS

Fifteen patients (83%) achieved fecal continence, 2 remain incontinent of stool, and 1 experienced stomal closure (mean follow-up was 24 +/- 9 months). Two patients had stomal stenosis that required revision. The mean enema volume in patient's achieving continence was 360 +/- 216 mL, and the mean transit time was 18 +/- 12 minutes.

CONCLUSIONS

LACE is an efficacious procedure for fecal incontinence that can be performed safely at the time of major urologic reconstruction. Administration of enemas into the left colon has several physiologic advantages that result in predictable bowel evacuation.

Modified cecal flap neoappendix for the Malone antegrade continence enema procedure: a novel technique

PURPOSE

We report our experience with the creation of a tubularized cecal flap to construct a neoappendix. This flap effectively serves as an alternative means of creating a conduit for antegrade continence enemas in patients who have either an absent or an unusable appendix.

MATERIALS AND METHODS

We reviewed our results from our initial 4 patients in whom we used this technique. A neoappendix is created from a medially based flap of distal cecum that is tubularized over a catheter and then buried in a seromuscular tunnel to create an antireflux mechanism. A skin stoma is then created.

RESULTS

All stomas are continent, functional and without any evidence of stenosis or necrosis of the cecal flap with followup ranging from 3 months to 8 years.

CONCLUSIONS

A medially based cecal flap neoappendix is an easily created and reliable conduit for antegrade enemas. This procedure should be considered within the surgical armamentarium of urologists and pediatric surgeons when the appendix is absent, atretic or fibrotic.

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

PURPOSE

Since introducing the Malone antegrade continence enema (MACE) procedure into our practice, it has been our bias that social confidence and independence are significantly improved and satisfaction is overwhelmingly high. We objectively determine outcomes after the MACE to refine patient selection, and maximize the quality of perioperative counseling and teaching.

MATERIALS AND METHODS

An anonymous questionnaire was mailed to all patients who had undergone the MACE procedure within the last 4 years. Patient/parent satisfaction, impact on quality of life and clinical outcome were assessed with Likert scales. Demographic information, MACE specifics, preoperative expectations, and unanticipated benefits and problems were also recorded.

RESULTS

A total of 65 questionnaires were returned from our first 92 patients (71%). Myelodysplasia was the primary diagnosis in 88% of patients. Complete or near complete fecal continence was achieved in 77% of patients and all others had improved incontinence. The highest level of satisfaction was reported by 89% of patients. Social confidence and hygiene were significantly improved. Daily time commitment, pain/cramping, intermittent constipation and time for fine-tuning the regimen were cited as unanticipated issues.

CONCLUSIONS

The MACE procedure has received high praise from patients and families after years of battling constipation and fecal incontinence. Significant improvement rather than perfection is the realistic expectation. Objective feedback from patients and families will continue to improve patient selection and education.

Laparoscopic antegrade continence enema (Malone) procedure: description and illustration of technique

The antegrade continence enema (ACE Malone) procedure has improved the lives of many patients who struggle with intractable forms of constipation. We describe a laparoscopic approach to this technique and review the literature.

Appendicostomy for antegrade enema: effects on somatic and psychosocial functioning in children with myelomeningocele

OBJECTIVE

To assess changes in somatic variables, psychosocial functioning, mental health and self-esteem after appendicostomy for antegrade enema (MACE) in children with myelomeningocele (MMC).

METHODS

We performed the MACE procedure in 20 children, aged 6.3 to 17.0 years. Twelve patients had an open and 8 had a laparoscopic operation. Somatic function was assessed preoperatively and 6 and 16 months postoperatively. Psychosocial functioning and mental health were assessed preoperatively and 6 months postoperatively by a structured clinical interview and standardized questionnaires, Youth Self-Report, Child Behavior Checklist, and Harter's Self-Perception Profile for Adolescents.

RESULTS

Preoperatively, 9 patients had fecal leaks several times a week, 7 had leaks 1 to 4 times per month, and 4 were continent. The corresponding numbers 6 and 16 months postoperatively were 0, 6, and 14 and 0, 3, and 16. Six patients have had postoperative stoma complications that required surgery; 5 had a well-functioning stoma thereafter, and 1 had a colostomy 7 months later. Preoperatively, 14 patients reported considerable, 4 moderate, 2 minor, and 0 no psychosocial problems related to bowel control and emptying regimen. Six months postoperatively, the corresponding numbers were 1, 2, 6, and 11. The standardized questionnaires revealed substantial psychopathology in the MMC patients. The Child Behavior Checklist and Youth Self-Report scores were not significantly changed postoperatively, but global self-esteem score and close friends score from the Self-Perception Profile for Adolescents were significantly improved.

CONCLUSIONS

Fecal incontinence and constipation were greatly reduced by MACE. Children with MMC often have psychological and psychosocial problems, but important improvements in self-esteem and psychosocial function were observed 6 months after the MACE procedure.

Appendiceal versus ileal segment for antegrade continence enema

PURPOSE

To assess outcomes after the antegrade continence enema procedure, we present our results with an ileal segment or the appendix in children with severe bowel dysfunction.

MATERIALS AND METHODS

A retrospective review of 45 children who had undergone the creation of a continent cecostomy for severe chronic constipation and fecal incontinence was performed.

RESULTS

The appendix was used to create the continent cecostomy in 28 patients (group 1) and ileum 17 (group 2). Of 16 patients who underwent simultaneous construction of appendiceal Mitrofanoff neourethra, including continent catheterizable stoma, the appendix was split and used for the cecostomy and neourethra in 11. Overall, acceptable continence was achieved in 39 (87%) patients and total continence 31 (69%). No significant difference was noted in the rate of continence between groups 1 and 2. Nonstomal postoperative complications occurred in 5 patients in group 1 and 3 group 2. Complications that required reoperation related to the continent cecostomy occurred in 10 patients, including stomal stenosis in 8, with 6 group 1 and 2 group 2 (p >0.05), and stricture in 2, with 1 group 1 and 1 group 2. There were 2 patients who had previously undergone colostomy for intractable constipation who were undiverted at the time of the creation of continent cecostomy. Both were continent postoperatively. There were 3 patients, including those 2 who presented with chronic severe constipation of unclear etiology, who underwent colostomy for unrecoverable colonic dys-motility, of whom 1 subsequently required total colectomy.

CONCLUSIONS

The creation of a continent cecostomy for antegrade continence enema is a successful management option in children with debilitating fecal incontinence, and may enable undiversion of an existing colostomy. The appendix and ileal segment are viable options for the procedure, with no significant difference noted in continence or complication rates.

Outcome of the antegrade colonic enema procedure in children with chronic constipation

BACKGROUND

Chronic constipation and fecal incontinence in children related to pelvic trauma, congenital anomalies, or malignancy will eventually lead to significant social and psychologic stress. Maximal medical treatment (daily enemas and laxatives) can also be difficult to maintain in many children.

METHODS

At our children's hospital, 11 children with chronic constipation or fecal incontinence or both underwent the antegrade colonic enema (ACE) procedure. The operation involved constructing a conduit into the cecum using either the appendix (n = 8) or a "pseudo-appendix" created from a cecal flap (n = 3). We report our surgical results.

RESULTS

Mean child age was 9.6 (5 to 18) years. With a mean follow-up of 14 (6 to 24) months, 10 of the children (91%) had significant improvement and 7 children (64%) are completely clean with no soiling and controlled bowel movements after irrigation.

CONCLUSIONS

Regular colonic lavage after the ACE procedure allows children with chronic constipation and fecal incontinence to regain normal bowel habits and a markedly improved lifestyle. This procedure should be considered before colostomy in children and adults for the treatment of fecal incontinence from a variety of causes.

The Malone antegrade colonic enema isolated or associated with urological incontinence procedures: evaluation from patient point of view

PURPOSE

Fecal and urinary incontinence in patients with congenital or acquired spinal cord defects represents a handicap that impairs chances of integration in society. Associated with the management of urinary incontinence, the Malone antegrade colonic enema is a generally successful procedure for resolving refractory fecal incontinence. We report the results of the evaluation of this technique from the patient perspective.

MATERIALS AND METHODS

A survey was conducted among 19 patients who had undergone a Malone procedure, combined in 14 with urological surgical intervention for urinary incontinence. Patients completed a questionnaire either by mail or during an interview with a urotherapy nurse and/or a psychologist. Questions concerned patient opinion about the quality of preoperative information, perioperative period, stoma, functional result and overall satisfaction. The psychological impact of the procedure was also evaluated during the interviews. No complication occurred related to the Malone procedure or stomal stenosis, and a perfect functional result was achieved in 17 patients, 1 of whom had occasional leakage through the stoma.

RESULTS

Of the 19 patients in the study 2 who have abandoned using the Malone procedure, including 1 with a poor result and 1 with a good functional result, did not return the questionnaire. The remaining 17 patients believed they had received adequate preoperative information and expressed no specific complaint about the perioperative period. The 15 with the stoma in the umbilicus were satisfied, although 3 young patients were temporarily disturbed by catheterizing the umbilicus and 2 with the stoma in the right fossa iliaca were disappointed. The 15 patients who had a perfect functional result recognized great improvement in quality of life but 13 complained of pain (12) and/or excessive duration of the procedure (9). The patient with a poor functional result and the other with occasional stomal leakage would not consider the procedure again. These 2 patients had durable postoperative depression while 3 others who ultimately achieved a good functional result experienced temporary depression.

CONCLUSIONS

The Malone procedure generally meets the expectations of patients but it is considered by a majority as painful and lengthy. The umbilicus is the preferred stoma site but may prove to be disturbing in young patients. Abandonment of the procedure and postoperative depression experienced by some patients, despite a good functional result, deserve better prevention.

Abandonment of the procedure and postoperative depression experienced by some patients, despite a good functional result, deserve better prevention.

Percutaneous colonoscopic cecostomy for management of chronic constipation in children

BACKGROUND

Chronic constipation and encopresis are common problems in children with spina bifida and anorectal anomalies. Commonly used therapies include complicated bowel regimens and antegrade continence enemas delivered via surgically placed appendicostomies and radiologically placed cecostomies.

METHODS

A technique is described for percutaneous placement of cecostomies for the delivery of continence enemas or venting.

RESULTS

Percutaneous cecostomies were placed in 12 patients. Improvement in bowel management occurred in all patients.

CONCLUSIONS

Percutaneous endoscopic cecostomy is a safe and effective method for the treatment of intractable constipation.

Idiopathic Constipation and Fecal Incontinence

Patients with constipation or fecal incontinence have great potential for remediation. Both disorders warrant a thorough diagnostic evaluation to search for remediable causes, especially to identify defecation disorders. Constipation should be treated by relieving any impactions and then starting a course of fiber supplementation of at least 20 g per day. If not successful, other agents such as lactulose, polyethylene glycol solutions, or stimulants can be added. Biofeedback may be very helpful. If all else fails, several surgical procedures are available. Fecal incontinence should be treated by fiber supplements, encouragement of regularity, and enemas as needed. Kegel exercises and biofeedback are often helpful, but surgery may be needed and is most effective in recent onset or traumatically induced incontinence.
