RESUMO
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.

INTRODUCTION: Filum section (FS) has been used to treat tethered cord syndrome (on MRI or occult) in pediatric patients with refractory dysfunctional voiding (DV). While controversial, some groups have previously reported significant improvement in patients' symptoms after FS, even in the presence of a normal preoperative spinal MRI. Until recently, it was our practice to refer patients with DV to pediatric neurosurgery for evaluation, MRI, and possible FS. OBJECTIVES: We report our experience with sacral nerve stimulator (SNS) placement for pediatric patients with refractory DV after failed FS with the primary outcome being complications and explantations. The secondary outcome being change in quality of life. STUDY DESIGN: We retrospectively reviewed all consecutive patients <18 years old who underwent second stage SNS placement after FS at our institution between November 2012 and December 2019. We abstracted rate of 2nd stage implantation, complication, and explantation. We also collected age-appropriate preoperative and postoperative 15-question quality of life questionnaires (PedsQL™). The PedsQL scores ranged 0-100, higher numbers correlating with higher quality of life. A paired t-test was used for statistical analysis. RESULTS: Overall, 23 children proceeded to the second stage SNS due to persistent symptoms following FS. Median age at SNS implantation was 10.3 years (IQR 7.5-11.8 years), and 13 were female (56.5%). There were no intraoperative complications. Median follow-up was 2.8 years (IQR 1.1-3.7 years). One patient had the SNS removed due to a need for MRI, one for resolution of symptoms, and 4 patients underwent lead revision for lead fracture and return of symptoms (17.4%). All 15 patients who completed both preoperative and postoperative PedsQL reported significantly improved overall scores after SNS (Figure). Median scores improved from 61.7 to 86.7 (p < 0.0001). DISCUSSION: Symptom relief in the child with refractory DV using SNS is not new. However, we sought to review our results in those with previous FS for tethered cord syndrome. While our study is limited by its small size, we assessed both surgical and patient-reported outcomes. Our patients' marked improvement in quality of life is similar to that of other reported pediatric SNS cohorts. CONCLUSION: SNS placement after FS is feasible, safe, and can result in significant improvement in overall quality of life. Given these findings, we have changed our practice to offer SNS in patients with refractory DV with a normal lumbosacral spinal MRI. For those with MRI abnormalities, we seek neurosurgical evaluation for FS (if deemed necessary) prior to considering SNS.

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.

PURPOSE: We describe our experience with robot-assisted complex lower urinary tract reconstruction in patients with a history of open abdominal surgery. MATERIALS AND METHODS: Patients with any previous open abdominal surgery undergoing robot-assisted complex lower urinary tract reconstruction were included. Complex lower urinary tract reconstruction was defined as bladder neck reconstruction or continent catheterizable conduits or both, redo surgery at the bladder neck for persistent incontinence or any of these procedures with creation of a Malone antegrade continence enema. Ureteral and renal surgeries were excluded. Patient demographics, surgery performed, operative techniques, operative times and outcomes were assessed. RESULTS: A total of 36 patients met inclusion criteria, of whom 21 had undergone multiple laparotomies for ventriculoperitoneal shunt revision, 14 had undergone laparotomy with other adjunct procedures and 1 had undergone laparotomy with colostomy. No access injury occurred and there were 5 conversions. Mean operative time was 8.2 hours (range 4 to 12) and mean length of hospital stay was 74.9 hours (23 to 216). The first 18 cases took longer than the last 18 cases (mean 9.1 vs 7.5 hours, p = 0.002). Patients with multiple ventriculoperitoneal shunt revisions had higher conversion rates (p = 0.01) and longer mean operative times (p = 0.002). Patients with a history of multiple ventriculoperitoneal shunt revisions also had longer hospital stays (p = 0.02). CONCLUSIONS: Robot-assisted complex lower urinary tract reconstruction in patients with previous open abdominal surgery is safe and feasible. Longer operative times should be expected early in the experience of a surgeon. Patients with multiple prior ventriculoperitoneal shunt revisions had higher conversion rates and longer operative times compared to those with other indications for prior surgery.

PURPOSE: The need for mechanical inpatient bowel preparation (IBP) in reconstructive pediatric urology has come under scrutiny, secondary to literature demonstrating little benefit regarding outcomes. Starting in 2013, a majority of patients undergoing reconstructive procedures at our institution no longer underwent IBP. We hypothesized that outpatient bowel preparation (OBP) would reduce length of stay (LOS) without increasing postoperative complications after appendicovesicostomy surgery. MATERIALS AND METHODS: An institutional database of patients undergoing lower urinary tract reconstruction between May 2010 and December 2014 was reviewed. Starting in 2013, a departmental decision was made to replace IBP with OBP. Patients undergoing an augmentation cystoplasty or continent ileovesicostomy were excluded because of insufficient numbers undergoing OBP. Patients undergoing IBP were admitted 1 day prior to surgery and received polyethylene glycol/electrolyte solution. A personalized preoperative OBP was introduced in 2013. Cost data were obtained from the Pediatric Health Information System. RESULTS: Sixty-seven patients met the inclusion criteria, with 30 (44.8%) undergoing IBP. There were no differences with respect to gender, age, presence of ventriculoperitoneal shunt, body mass index, glomerular filtration rate, preoperative diagnosis, operative time, and prior or simultaneous associated surgeries (p ≥ 0.07). Patients undergoing an IBP had a longer median LOS (7 vs. 5 days, p = 0.0002) and a higher median cost (US$4,288, p = 0.01). Postoperative complications in both groups were uncommon and were classified as Clavien-Dindo grade 1-2, with no statistical difference (IBP 20.0% vs. OBP 5.4%, p = 0.13). No serious postoperative complication occurred, such as a dehiscence, bowel obstruction, or shunt infection. DISCUSSION: This is the first analysis of hospitalization costs and IBP, showing a higher median cost of US$4288 compared with OBP. The LOS was shorter with an OBP (figure), similar to a previous report. Similar complication rates between the groups add to the growing body of literature that avoidance of IBP is safe in pediatric lower urinary tract reconstruction. Being a retrospective review of a practice change, differences in care that influenced cost and LOS may be missing. Also, as the surgeons do not know if a usable appendix is initially present, our data may not extrapolate to all patients. Despite these potential limitations, our data support the safety of utilizing OBP in patients with a high likelihood of a usable appendix, including those undergoing a synchronous Malone antegrade continence enema via a split-appendix technique. CONCLUSION: In patients undergoing an appendicovesicostomy, preoperative IBP led to longer LOS and higher costs of hospitalization. OBP was not associated with increased risks of postoperative complications.

INTRODUCTION: Serum B12 deficiency is a known sequlae of enterocystoplasty. The complications of B12 deficiency include megaloblastic anemia, neuropsychiatric disease, and demyelinating diseases such as peripheral neuropathy. Some studies have suggested that underlying disease states may be more important than enteric absorptive capacity in predicting acquired B12 deficiency. A 38% incidence of low or low-normal serum B12 in patients who have undergone enterocystoplasty has previously been reported, and oral B12 supplementation has been demonstrated to be an effective short-term therapy; however, the long-term results remain unclear. AIMS: This study hypothesized that oral vitamin B12 supplementation in patients with B12 deficiency following enterocystoplasty is an effective long-term treatment. Additionally, it sought to determine if underlying disease state predicts B12 deficiency following enterocystoplasty. DESIGN: Children who underwent enterocystoplasty at the present institution prior to August 2007 were reviewed. Patients with non-ileal augment, insufficient follow-up or hematologic disorders were excluded. Patients with low or low-normal B12 levels were included. Treatment consisted of daily oral therapy of 250 mcg or monthly parenteral therapy of 1000 mcg IM. Separately, the institutional database of 898 patients who underwent enterocystoplasty was searched and patients with at least one post-operative B12 level were highlighted. The indication for enterocystoplasty was classified as neuropathic or non-neuropathic. RESULTS: Twenty-three patients met inclusion criteria. The mean follow-up was 49 months (range 5-85) following initial abnormal B12 level. On the last follow-up, 4/23 (17%) patients had normal serum B12 levels. No patients reported sequelae of long-term B12 deficiency. In the secondary investigation, 113 patients met inclusion criteria. A total of 101 had neuropathic indications for enterocystoplasty, and 12 had non-neuropathic indications. At any time during follow-up, 48/101 (47.5%) neuropathic patients had low or low-normal B12 levels, and 4/12 (33.3%) non-neuropathic patients had low or low-normal B12 levels during follow-up (P = 0.54) (Figure). DISCUSSION: The initial success of oral B12 deficiency treatment following enterocystoplasty does not persist over time. This contradicts previous results with short duration follow-up. Underlying disease as the indication for enterocystoplasty did not predict B12 deficiency risk. The study was limited by the small number of patients with B12 deficiency who were started on treatment, as well as by the small number of patients with non-neuropathic indications for enterocystoplasty. CONCLUSION: The aims of the study were met. Further investigation is required to assess predictors of B12 deficiency following enterocystoplasty.
