Surgery for chronic idiopathic constipation: pediatric and adult patients - a systematic review.

BACKGROUND: Chronic idiopathic constipation (CIC) is a substantial problem in pediatric and adult patients with similar symptoms and workup; however, surgical management of these populations differs. We systematically reviewed the trends and outcomes in the surgical management of CIC in pediatric and adult populations. METHODS: A literature search was performed using Ovid MEDLINE, Embase, Scopus, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov between January 1, 1995 and June 26, 2020. Clinical trials and retrospective and prospective studies of patients of any age with a diagnosis of CIC with data of at least 1 outcome of interest were selected. The interventions included surgical resection for constipation or antegrade continence enema (ACE) procedures. The outcome measures included bowel movement frequency, abdominal pain, laxative use, satisfaction, complications, and reinterventions. RESULTS: Adult patients were most likely to undergo resection (94%), whereas pediatric patients were more likely to undergo ACE procedures (96%) as their primary surgery. Both ACE procedures and resections were noted to improve symptoms of CIC; however, ACE procedures were associated with higher complication and reintervention rates. CONCLUSION: Surgical management of CIC in pediatric and adult patients differs with pediatric patients receiving ACE procedures and adults undergoing resections. The evaluation of resections and long-term ACE data in pediatric patients should be performed to inform patients and physicians whether an ACE is an appropriate procedure despite high complication and reintervention rates or whether resections should be considered as an initial approach for CIC.

Endoscopic retrieval of migrated Foley catheter: A clinical case series.

Use of Foley catheter in patients with ileostomy, for the decompression of large bowel distal to stoma or for the administration of large bowel enema through colostomy, either to treat constipation or for bowel preparation prior to colonoscopy, is a common practice. Accidental migration of catheter during bowel irrigation through stoma can take place if it is not secured externally to the skin. We present 2 such cases with intra-colonic migration of Foley catheter that occurred during bowel irrigation and were retrieved endoscopically. To our knowledge, this is the first case report of endoscopic removal of Foley catheter that migrated internally through the stoma.

Sacral Neuromodulation for defecation disorders after non oncologic pelvic surgery.

PURPOSE: Defecation disorders (DD) can sometimes affect the outcomes of pelvic or colorectal surgery. The aim of the present study is to evaluate the role of sacral neuromodulation for the treatment of constipation and other evacuation disorders after surgery. METHODS: A retrospective analysis in all the consecutive patients that underwent sacral nerve modulation (SNM) for DD arisen or worsened after pelvic or colorectal surgery was performed from January 2010 to December 2020. DD were defined starting from Rome IV Criteria, and according to manometric results, all patients were further divided into the two subgroups: inadequate defecatory propulsion and dyssynergic defecation. Cleveland Clinic Constipations Score (CCCS) and SF-36 have been evaluated in the time. RESULTS: Thirty-seven patients have been included in the study. Twenty-seven out of thirty-seven (73.3%) patients had experienced sufficient benefits to implant the definitive device, and 22 patients (59.4% of tested and 81.5% of permanently implanted) still had the device functioning after a mean follow-up of 6.3 years. The most represented manometric pattern was inadequate propulsive function (59% of patients). CCCS at preoperative assessment for all patients was 17.5 with a reduction to 10.4 at the first year of follow-up (p < 0.001). CONCLUSION: SNM appears to be a feasible, safe, and well-tolerated procedure with durable benefit in the long-term treatment of defecatory dysfunction after pelvic or colorectal surgery for benign diseases.

The impact of antegrade continence enemas on bladder function in patients with neurogenic bladder and bowel.

INTRODUCTION: In neurologically intact children with constipation and lower urinary tract symptoms, treatment of constipation frequently results in improved or resolved lower urinary tract symptoms. The impact of treatment of constipation on bladder function in children with a neurogenic bowel and bladder is not well studied. The objective of this study was to evaluate the impact of antegrade continence enemas (ACE) via Chait tube on urodynamic study (UDS) parameters and urinary continence in patients with neurogenic bowel and bladder (NGB). We hypothesized that following ACE some patients would demonstrate improved UDS parameters and improved urinary continence. MATERIALS AND METHODS: A review of patients with NGB who underwent a cecostomy was performed. Inclusion criteria required UDS within 12 months before and after Chait tube placement and no change in clean intermittent catheterization or anticholinergic medications. UDS parameters assessed included bladder capacity, bladder compliance, and bladder stability. In addition, the frequency of antegrade continence enemas and encopresis were reviewed as was the frequency of UTIs before and after the surgery. RESULTS: 8 children met inclusion criteria, including 5 girls and 3 boys, with a mean (range) age of 8.5 years (5-13). All children were on clean intermittent catheterization and 7 were on anticholinergic medications. The patients demonstrated a significant improvement in constipation and encopresis (p < 0.05). All but 1 patient had resolution of encopresis, and 6 of 7 patients who had constipation before ACE management had a resolution of constipation. 2 patients (25%) developed urinary continence (i.e., dry between CIC), and 2 others had improvement in continence. 3, 2, and 2 patients had urodynamic improvement in bladder capacity, compliance, or stability, respectively. However, no significant improvement in urinary incontinence or UDS parameters was demonstrated for the group overall. DISCUSSION: Our data demonstrate that some children with neurogenic bowel and bladder will have improvement in continence and UDS parameters following the initiation of ACE. Despite significant improvement in constipation and encopresis, the frequency of bladder improvement in this population appears less than that reported in neurologically intact children following treatment of constipation. Confirmatory studies with a larger number of children are needed. However, since constipation appears to negatively impact bladder function in some children with neurogenic bowel and bladder, it is reasonable to try to eliminate significant constipation in these patients before increasing pharmaceutical management of their neurogenic bladder.

Long-Term outcomes of cecostomy tube insertion for patients with bowel dysfunction: A retrospective review.

BACKGROUND: Constipation is common in the pediatric population and in severe forms it can lead to debilitating fecal incontinence which has a significant impact on quality of life. Cecostomy tube insertion is a procedural option for cases refractory to medical management, however there is limited data investigating the long-term success and complication rate. METHODS: A retrospective review was performed evaluating patients at our centre undergoing cecostomy tube (CT) insertion between 2002 and 2018. The primary outcomes of the study were the rate of fecal continence at 1-year, and the incidence of unplanned exchanges prior to annual scheduled exchange. Secondary outcomes include the frequency of anaesthetic requirements and length of hospital stay. Descriptive statistics, t-test, and chi-square analysis was performed where appropriate using SPSS v25. RESULTS: Of 41 patients, the average age at the time of initial insertion was 9.9 years with the average length of stay in hospital being 3.47 days. The most common etiology of bowel dysfunction was spina bifida, which was present in 48.8% (n = 20) of patients. Fecal continence was achieved in 90% (n = 37) of patients at 1 year and the average rate of cecostomy tube exchange was 1.3/year with an average of 3.6 general anaesthetics being required by patients and the average age of no longer requiring one being 14.9 years. DISCUSSION: Analysis of patients undergoing cecostomy tube insertion at our centre has further supported the use of cecostomy tubes as a safe and effective option for management of fecal incontinence refractory to medical management. However, a number of limitations exist in this study including its retrospective design and failure to investigate changes in quality of life using validated questionnaires. Additionally, while our research provides greater insight to practitioners and patients what degree of care and types of complications or issues they may encounter with an indwelling tube over the long-term, our single-cohort design limits any conclusions that could be made regarding optimal management strategies for overflow fecal incontinence through direct comparison with other management strategies. CONCLUSIONS: CT insertion is a safe and effective method for managing fecal incontinence due to constipation in the pediatric population, however, unplanned exchange of tube due to malfunction, mechanical breakage, or dislodgment occurs frequently and may impact quality of life and independence. LEVEL OF EVIDENCE: IV.

Functional constipation refractory to medical management: The colon is the problem.

BACKGROUND: Management of refractory constipation in children has not been standardized. We propose a protocolized approach which includes a contrast enema, anorectal manometry and exclusion of Hirschsprung disease (HD). For those without HD or with normal sphincters, an assessment of the colonic motility may be needed. The subgroups of dysmotility include (1) slow motility with contractions throughout, (2) segmental dysmotility (usually the sigmoid), or (3) a diffusely inert colon. We offered a Malone appendicostomy in all groups with the hope that this would avoid colonic resection in most cases. METHODS: Patients with medically refractory constipation were reviewed at a single institution (2020 to 2021). For patients without HD or an anal sphincter problem, assessment of colonic motility using colonic manometry was performed followed by a Malone appendicostomy for antegrade flushes. RESULTS: Of 196 patients evaluated for constipation refractory to medical management, 22 were felt to have a colonic motility cause. These patients underwent colonic manometry and Malone appendicostomy. 13 patients (59%) had a slow colon but with HAPCs throughout, 5 (23%) had segmental dysmotility, and 4 (18%) had a diffuse colonic dysmotility. 19 (86%) responded well to antegrade flushes with 17 reporting no soiling and 2 having occasional accidents. 3 patients (14%) failed flushes and underwent a colon resection within 6-month following Malone procedure. CONCLUSION: We propose a protocol for medically refractory constipation which provides a collaborative framework to standardize evaluation and management of these patients with antegrade flushes, which aids in avoidance of colonic resection in most cases. LEVEL OF EVIDENCE: Level IV.

Fecal continence disparities in patients with idiopathic constipation treated at referral institutions for pediatric colorectal surgery.

PURPOSE: Fecal continence is a concern for many patients with idiopathic constipation and can significantly impact quality of life. It is unknown whether racial, ethnic, and socioeconomic disparities are seen in fecal continence within the idiopathic constipation population. We aimed to evaluate fecal continence and associated demographic characteristics in children with idiopathic constipation referred for surgical evaluation. METHODS: A multicenter retrospective study of children with idiopathic constipation was performed at sites participating in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC). All patients >3y of age with idiopathic constipation diagnosis were included. The primary outcome was fecal continence, categorized as complete (no accidents ever), daytime (no accidents during the day), partial (occasional incontinence day/night), and none (incontinent). We evaluated for associations between fecal continence and race, sex, age, insurance status, and other patient-level factors, employing Kruskal-Wallis and trend tests. RESULTS: 458 patients with idiopathic constipation from 12 sites were included. The median age of diagnosis was 4.1 years. Only 25% of patients referred for surgical evaluation were completely continent. Age at the visit was significantly associated with fecal continence level (p = 0.002). In addition, patients with public and mixed public and private insurance had lower levels of continence (p<0.001). Patients with developmental delay were also more likely to have lower continence levels (p = 0.009) while diagnoses such as anxiety, ADD/ADHD, autism, depression, obsessive-compulsive disorder were not associated. Approximately 30% of patients had an ACE operation (antegrade continence enema) at a median age of 9.2 years at operation. Black patients were significantly less likely to undergo ACE operation (p = 0.016) when compared to white patients. CONCLUSION: We observed data that suggest differences in fecal incontinence rates based on payor status. Further investigation is needed to characterize these potential areas of disparate care. LEVEL OF EVIDENCE: Level III.

Do preoperative factors predict success of antegrade continence enemas in children?

INTRODUCTION: Antegrade continent enemas (ACE) procedures are one treatment option in children with medically refractory constipation or encopresis and predicting success is difficult. We hypothesize that there are preoperative factors that can be identified to help with patient selection and family counseling. METHODS: We conducted a retrospective study of children who underwent a cecostomy or appendicostomy for an ACE program between 2015 and 2021. Underlying diagnosis, pre-operative bowel regimen and imaging were analyzed. Patients were reviewed for success at 3-, 6- and 12-months post-procedure. Data was analyzed with Fisher's Exact, Kruskal-Wallis and logistic regression where applicable with significance defined as p < 0.05. RESULTS: Forty-three children were identified; 28 were male, 15 were female, mean age at time of operation was 8 years old. 76% were considered successful at 3-months, 86% at 6-months, and 87% at 12-months post- procedure. Univariate analysis showed that a pre-ACE retrograde enema program predicted success at 3-months (94% vs. 64% p = 0.03) but no difference at 6- or 12-months. At one year after ACE procedure there was a significant reduction in number of enteral medications (2 to 0, p < 0.01) and 94% of patients were on one or fewer at one year follow-up. Age, gender, weight at time of operation, contrast enema, anorectal manometry and colonic transit time results were not predictive of outcomes. CONCLUSION: In this study, we characterized expected time to success in our population as well as identified use of a pre-operative retrograde enema program as a potential predictor of success at 3-months in children undergoing an ACE procedure. LEVEL OF EVIDENCE: IV. TYPE OF STUDY: Prognosis study.

Procedimiento de malone videoasistido en pediatria: primeros dos casos en Uruguay / Laparoscopic malone procedure in pediatrics: first cases in Uruguay / Procedimento de malone videoassistido em pediatria: dois primeiros casos no Uruguai

El procedimiento de apendicostomía continente para la realización de enemas anterógrados ha sido publicado ya hace varios años para el tratamiento de la incontinencia fecal y del estreñimiento de muy difícil manejo. Otra indicación del mismo incluye el estreñimiento severo, en el cual se agotaron las medidas farmacológicas y el único tratamiento efectivo es la realización de enemas. El objetivo principal del procedimiento es ofrecer a los niños y sus familias una alternativa a la hora de realizar los enemas, logrando una mayor adherencia al tratamiento y buscando alcanzar una mejor calidad de vida que permita adecuarse a las actividades con sus pares. Por otra parte permite al niño ir logrando cierta independencia gradual a medida que crezca, preparándolos para el futuro y haciéndolos participes activos de su cuidado. Se describen los primeros casos en donde utilizamos en nuestro medio el abordaje laparoscópico, sus indicaciones, la técnica quirúrgica y los resultados iniciales. Hemos constatado como ventaja principal los beneficios del abordaje mínimamente invasivo, como la exploración completa de la cavidad abdominal, el menor dolor postoperatorio, cicatrices más pequeñas, menor creación de adherencias.

The appendicostomy procedure for performing antegrade enemas has been published several years ago for the treatment of fecal incontinence and constipation that are very difficult to manage. The Malone procedure is performed in our setting, especially in patients with fecal incontinence secondary to neurological disorders such as myelomeningocele using a conventional approach. Other indications of it is severe constipation, in which pharmacological measures have been exhausted and the only effective treatment is enemas. The main objective of the procedure is to offer children and their families an alternative when performing enemas, achieving greater adherence to treatment and seeking to achieve a better quality of life that allows them to adapt to the activities of their peers. On the other hand, it allows the child to achieve a certain gradual independence as they grow, preparing them for the future and making them active participants in their care. The first cases in which we use the laparoscopic approach, its indications, the surgical technique and the initial results are described. We think that its main advantage is the benefits of the minimally invasive approach, such as complete exploration of the abdominal cavity, less postoperative pain, smaller scars, and less creation of adhesions.

Long term outcome of antegrade colonic enema (ACE) stoma for treatment of constipation and fecal incontinence in children.

AIM: To determine the long term outcome of antegrade colonic enema (ACE) stoma for treatment of chronic constipation and soiling in children. METHOD: We reviewed patients prospectively who underwent formation of ACE stoma after failure of maximum medical treatment of chronic constipation and soiling from September 2008 to October 2020. All patients had anorectal manometry, endosonography and colonic transit study. A validated symptom severity (SS) score questionnaire was used pre operatively and during follow up. The sum of SS score ranged between 0 (best) and 65 (worst). Data was expressed as median(range) and Wilcoxon rank sum test was used and p value < 0.05 was considered significant. RESULTS: 58 patients had formation of ACE stoma, laparoscopic appendicostomy 56, cecostomy 1, and open procedure 1. The main indications for the ACE stoma were chronic functional constipation (FC) 50(86%), anorectal malformations (ARM) 6(11%) and Hirschsprung disease (HD) 2(3%). 41(71%) of patients had previous intrasphincteric botulinum toxin (BT) treatment. Age at operation was 11(range 4-15) years and follow up was 36(3-84) months. 47(81%) patients were continent of stool within three months postoperatively. The preoperative SS score improved from 34/65 (26-47) to 8/65 (4-12) at 12 months and 5/65 (2-11) at 24 months follow up, p ≤ 0.05. OVERALL: complication rate was 15(26%), wound infection 5, granulation tissue 4, stoma prolapse 4, retraction 1, abscess formation and fistula 1. 15 (26%) adolescents had transition of their care to adult services. CONCLUSION: There is a significant improvement of constipation, soiling and general health of patients following formation of ACE stoma. Adolescents benefits an orderly transition of their care to adult services. LEVEL OF EVIDENCE: Level 2, Therapeutic study.

Antegrade continence enemas in children with functional constipation and dyssynergic defecation: Go or no go?

OBJECTIVE: To assess outcomes of children with functional constipation after antegrade continence enemas (ACEs) and determine if pre operative anorectal manometry (AMAN) findings, including dyssynergic defecation, are associated with outcomes. METHODS: A retrospective review of pediatric patients with functional constipation who received a Malone appendicostomy or cecostomy after failed medical management was conducted. Patients were included if they had AMAN data prior to their operation. Patients that underwent colonic resection were excluded. Demographics, clinical characteristics, manometry results, and post ACE outcomes were obtained. Descriptive statistics were performed. RESULTS: Thirty-nine patients were identified with median age at ACE of 8.9 years (IQR: 7.2-12.6) and median follow-up of 2.5 years (IQR: 1.8-3.2 years). Twenty patients (51%) were female and most (35, 92%) were White. All patients had severe constipation prior to ACE and 59% had fecal incontinence. Thirty-four patients (87%) received a Malone and 5 (13%) received a cecostomy. Post ACE, 35 (90%) were clean with daily flushes and 6 (15%) eventually successfully transitioned to laxatives only. Awake AMAN and balloon expulsion test were performed in 15 patients, with 14 (93%) displaying evidence of dyssynergic defecation. Twelve of 14 of patients (86%) with dyssynergia were clean with ACE at follow-up. because of the majority of patients being clean post ACE, there was limited power to detect predictors of poor outcomes. CONCLUSIONS: ACEs are successful treatment options for patients with severe constipation and fecal incontinence, including those with dyssynergic defecation. Larger studies are needed to identify factors predictive of poor outcomes. LEVEL OF EVIDENCE: III.

Transition and reversal: long-term experience of the MACE procedure in children.

PURPOSE: Analysis of outcomes and follow-up of children who underwent the Malone antegrade continence enema (MACE) procedure in a UK tertiary paediatric surgery unit. METHODS: Children who underwent a MACE procedure from 1998 to 2020 were identified. Demographic and clinical data were obtained from contemporaneous records. Outcomes were categorised as full (success), partial or failure. RESULTS: Ninety-five children were identified for inclusion (chronic idiopathic constipation (CIC, 59), anorectal malformations (ARM, 23) and Hirschsprung's disease (HD, 13)). Mean age at surgery was 9.4 years (3-19 years) and mean follow-up time was 6 years (0.3-16.8 years). Outcomes were successful in 69% of CIC patients, 78% in ARM and 69% in HD. Twenty (21%) underwent MACE reversal after developing independent continence, with a significant difference between groups (CIC 19%, ARM 9%, HD 54%, p = 0.0047). 50% of patients > 16 years old were transitioned to adult services. CONCLUSION: We report a success rate of 72% for MACE procedures in our unit, with a significant difference in reversal rate between diagnostic groups. Long term, a fifth of patients no longer required their MACE. When these patients reach adolescence, those who require ongoing support outside of the paediatric surgery setting should be safely transitioned to adult services.

Comparing quality of life improvement after antegrade continence enema (ACE) therapy for patients with organic and functional constipation / encopresis.

BACKGROUND: We compared patient- and family-reported overall and stool-related quality of life (QoL) before and after an antegrade continence enema (ACE) procedure (cecostomy tube insertion) for refractory chronic constipation or fecal incontinence (CCFI). We hypothesized that patients with functional diagnoses experience similar improvements in QoL compared to those with organic diagnoses. METHODS: This is a cross-sectional study of patients undergoing cecostomy tube insertion for CCFI at a tertiary pediatric hospital from 2012 to 2019. Patients and/or primary caregivers completed validated stooling and overall QoL surveys based on three time points: before surgery, three months after surgery, and at the time of survey / date of last follow-up. Repeated measures analyses compared scores over time between subjects and within the diagnostic groups. RESULTS: The response rate was 65% (22/34 patients, 12 organic and 10 functional diagnoses). Mean age was 8.3 years and 32% of the participants were female. Organic diagnoses were: spina bifida (6), anorectal malformation (5), and Hirschsprung Disease (1). There was substantial improvement in stool-related and overall QoL at three months post-ACE procedure (both p<0.001) for all patients; both scores continued to improve significantly until the date of last follow-up (median 4.1 years, IQR 2.3-5.6, p<0.001). There was no statistically significant difference in scores between patients with organic and functional diagnoses. CONCLUSIONS: Caregivers perceive a significant, sustainable improvement in stooling habits and QoL following ACE therapy. The improvement is comparable between patients with a functional diagnosis and those with an underlying organic reason for their CCFI.

Laparoscopic-asisted percutaneus endoscopic cecostomy (LAPEC) in the treatment of severe constipation of adults - single center study.

INTRODUCTION: Effective treatment for chronic constipation is a real clinical challenge, especially in patients with severe symptoms. If conservative measures do not help, usually subtotal colectomy with ileorectal anastomosis has been used as the treatment of choice for refractory slow-transit constipation, but consequences may unfavorably affect quality of life. Percutaneous endoscopic caecostomy (PEC) with antegrade colonic enema (ACE) is a minimally invasive alternative to avoid radical surgery in order to improve bowel movement. Recently, of various catheter placement techniques, a laparoscopic-assisted percutaneous endoscopic cecostomy has been applied in clinical praxis. METHODS: We performed retrospective analysis of 5 patients with Chait Trapdoor catheter placed for purpose of ACE by LAPEC. Main outcome was to assess clinical success of PEC defined by an improvement of at least 50% of baseline KESS at 6M. Secondary outcomes were: procedural parameters and safety of procedure. RESULTS: Since may 2019 to march 2021, LAPEC was performed in 5 patients. Median follow-up was 14 months (7V12). All PECs were placed successfully in cecum. Treatment success reached 60% (3/5) of patients. Postoperative complication occurred in three patients. CONCLUSION: LAPEC provides both endoscopic and laparoscopic visualization, thereby, significantly decreasing potential risks by ensuring precise and safe access to the cecum. Antegrade colonic enema through PEC provides improvement of bowel movement in highly selected patient with severe symptoms.

The Macedo-Malone antegrade colonic enema: A minimal invasive technique that precludes appendix use.

INTRODUCTION: Antegrade continence enema (ACE) is recommended for patients with fecal incontinence/constipation refractory to conservative management. The Malone ACE utilizes the appendix as a catheterizable channel whereas the Macedo-Malone (MM) precludes the use of the appendix. We aimed to illustrate the MM procedure. METHODS: The left colon is brought out through a small transverse incision on the upper left abdomen and a 3-cm transverse flap in a tenia is created. A 12-Fr silicone Foley catheter is placed on the mucosal surface of the flap to allow creating a tubular conduit. After closure of the anterior wall colonic, the continence valve mechanism is produced by embedding the tube over a serous lined tunnel created by interrupted sutures. The distal portion of the tube is anastomosed into a V shape to the skin flap to avoid stoma stenosis. DISCUSSION: The advantage of this technique is the all-the time availability for not requiring the appendix which some authors prefer to use for urinary reconstruction. In a previous study, we have shown that the MM produces a high rate (89%) of fecal continence (Mean follow-up: 75 months). CONCLUSION: We are convinced that this procedure can be incorporated into fecal incontinence/constipation armamentarium.

Reducing Constipation-Related Admissions: The Effectiveness of Antegrade Continence Enema Procedures in Children.

INTRODUCTION: Constipation in pediatrics remains a common problem. Antegrade continence enema (ACE) procedures have been shown to decrease the distress of daily therapy. Patients are able to administer more aggressive washouts in the outpatient setting. Therefore, we hypothesize that patients following an ACE procedure would have reduced admissions for constipation. METHODS: Patients who underwent an ACE procedure at a large children's hospital from 2015 to 2018 were included. Demographics, diagnosis, procedure, and preoperative/postoperative hospital admissions were analyzed. RESULTS: Forty-eight patients were included in the study. Over half were diagnosed with idiopathic constipation. Majority of patients underwent an appendicostomy (88%, n = 42). Preoperatively, 26 patients were admitted for a combined total of 63 times for constipation. Postoperatively, 4 patients were admitted for a total of 5 visits (P = .021). Twenty-eight patients required a nonscheduled appendicostomy tube replacement. CONCLUSION: This study demonstrates ACE procedures can improve constipation-related symptoms in children and are associated with decrease hospital admissions.

Transumbilical laparoscopy-assisted Malone procedure for fecal incontinence in children.

BACKGROUND: Transumbilical laparoscopy-assisted Malone procedure (TULAM) is a single-incision laparoscopic procedure in which the appendicostomy is made at umbilicus. The aim of this study is to evaluate the outcomes of TULAM. METHODS: With IRB approval, the medical records of the patients who underwent TULAM were retrospectively reviewed between July 2013 and December 2018. The data collected included ages, gender, underlying diseases, operative techniques, complications, stoma continence, parental satisfaction and follow-up duration. RESULTS: Fifteen patients underwent TULAM at the median age of 5.0 years (2.9-10.7 years). There were 4 girls and 11 boys. Thirteen patients had anorectal malformations or cloaca; the other two patients had spina bifida. All patients presented with fecal incontinence; 9 of them had concomitant constipation. TULAM was successfully accomplished in 14 patients; one patient required conversion to the three-port procedure. The median follow-up period was 1.7 years (0.5-3.2 years). One patient required tube replacement under endoscopy guidance in the operation room. One patient required surgical revision because the appendix was disrupted after an episode of enterocolitis. All patients were socially continent with antegrade enemas. 12 patients were stoma continent, and 3 patients had minor leaking less than once a month. The stoma cosmesis was satisfactory. All parents expressed satisfaction with TULAM. CONCLUSION: TULAM is effective in the management of fecal incontinence and constipation, and provides a continent stoma with excellent cosmesis.

Preservation of superior rectal artery in laparoscopically assisted subtotal colectomy with ileorectal anastomosis for slow transit constipation.

BACKGROUND: Slow transit constipation (STC) has traditionally been considered as a functional disorder. However, evidence is accumulating that suggests that most of the motility alterations in STC might be of a neuropathic etiology. If the patient does not meet the diagnosis of pelvic outlet obstruction and poorly response to conservative treatment, surgical intervention with subtotal colectomy may be effective. The most unwanted complication of the procedure is anastomotic leakage, however, preservation of the superior rectal artery (SRA) may reduce its incidence. AIM: To evaluate the preservation of the SRA in laparoscopically assisted subtotal colectomy with ileorectal anastomosis in STC patients. METHODS: This was a single-center retrospective observational study. STC was diagnosed after a series of examinations which included a colonic transit test, anal manometry, a balloon expulsion test, and a barium enema. Eligible patients underwent laparoscopically assisted total colectomy with ileorectal anastomosis and were examined between January 2016 and January 2018. The operation time, blood loss, time to first flatus, length of hospital days, and incidence of minor or major complications were recorded. RESULTS: A total of 32 patients (mean age, 42.6 years) who had received laparoscopic assisted subtotal colectomy with ileorectal artery anastomosis and preservation of the SRA. All patients were diagnosed with STC after a series of examinations. The mean operative time was 151 min and the mean blood loss was 119 mL. The mean day of first time to flatus was 3.0 d, and the mean hospital stay was 10.6 d. There were no any patients conversions to laparotomy. Post-operative minor complications including 1 wound infection and 1 case of ileus. There was no surgical mortality. No anastomosis leakage was noted in any of the patients. CONCLUSION: Laparoscopically assisted subtotal colectomy with ileorectal anastomosis and preservation of the SRA can significantly improve bowel function with careful patient selection. Sparing the SRA may protect against anastomosis leakage.

Ileal Neoappendicostomy in the Treatment of Fecal Incontinence in Children.

INTRODUCTION: An antegrade colonic enema (ACE) via an appendicostomy has been shown to be effective in the management of functional bowel problems. In cases with a missing appendix, a neoappendicostomy may be considered. MATERIALS AND METHODS: A retrospective review of clinical outcomes in children who underwent ileal neoappendicostomy for ACE. Medical records were reviewed for data on demography, intra- and postoperative complications. A follow-up questionnaire on stoma problems, ACE-related problems, bowel function, patient satisfaction, well-being, and effect on daily activities was performed. RESULTS: Ten patients were included at an average age of 10.6 years at surgery. In half of the patients, minor postoperative complications (Clavien-Dindo grade 2 or less) were found. Nine patients answered the questionnaire with a mean follow-up of 57 months. Despite complaints of stomal leakage, difficulties with catheterization, and pain during irrigation, they reported a high grade of satisfaction, improvements in well-being, and bowel function and the achievement of continence. CONCLUSION: Ileal neoappendicostomy may be an alternative to ACE in children with severe and medically intractable constipation and or/and fecal incontinence where the appendix is missing or not available.
