Abstract
BACKGROUND Constipation that is prolonged and does not resolve with conventional therapeutic measures is called intractable constipation. The treatment of intractable constipation is challenging, involving pharmacological or non-pharmacological therapies, as well as surgical approaches. Unresolved constipation can negatively impact quality of life, with additional implications for health systems. Consequently, there is an urgent need to identify treatments that are efficacious and safe. OBJECTIVES To evaluate the efficacy and safety of treatments used for intractable constipation in children. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, and two trials registers up to 23 June 2023. We also searched reference lists of included studies for relevant studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing any pharmacological, non-pharmacological, or surgical treatment to placebo or another active comparator, in participants aged between 0 and 18 years with functional constipation who had not responded to conventional medical therapy. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were symptom resolution, frequency of defecation, treatment success, and adverse events; secondary outcomes were stool consistency, painful defecation, quality of life, faecal incontinence frequency, abdominal pain, hospital admission for disimpaction, and school absence. We used GRADE to assess the certainty of evidence for each primary outcome. MAIN RESULTS This review included 10 RCTs with 1278 children who had intractable constipation. We assessed one study as at low risk of bias across all domains. There were serious concerns about risk of bias in six studies. One study compared the injection of 160 units botulinum toxin A (n = 44) to unspecified oral stool softeners (n = 44). We are very uncertain whether botulinum toxin A injection improves treatment success (risk ratio (RR) 37.00, 95% confidence interval (CI) 5.31 to 257.94; very low certainty evidence, downgraded due to serious concerns with risk of bias and imprecision). Frequency of defecation was reported only for the botulinum toxin A injection group (mean interval of 2.6 days). The study reported no data for the other primary outcomes. One study compared erythromycin estolate (n = 6) to placebo (n = 8). The only primary outcome reported was adverse events, which were 0 in both groups. The evidence is of very low certainty due to concerns with risk of bias and serious imprecision. One study compared 12 or 24 μg oral lubiprostone (n = 404) twice a day to placebo (n = 202) over 12 weeks. There may be little to no difference in treatment success (RR 1.29, 95% CI 0.87 to 1.92; low certainty evidence). We also found that lubiprostone probably results in little to no difference in adverse events (RR 1.05, 95% CI 0.91 to 1.21; moderate certainty evidence). The study reported no data for the other primary outcomes. One study compared three-weekly rectal sodium dioctyl sulfosuccinate and sorbitol enemas (n = 51) to 0.5 g/kg/day polyethylene glycol laxatives (n = 51) over a 52-week period. We are very uncertain whether rectal sodium dioctyl sulfosuccinate and sorbitol enemas improve treatment success (RR 1.33, 95% CI 0.83 to 2.14; very low certainty evidence, downgraded due to serious concerns with risk of bias and imprecision). Results of defecation frequency per week was reported only as modelled means using a linear mixed model. The study reported no data for the other primary outcomes. One study compared biofeedback therapy (n = 12) to no intervention (n = 12). We are very uncertain whether biofeedback therapy improves symptom resolution (RR 2.50, 95% CI 1.08 to 5.79; very low certainty evidence, downgraded due to serious concerns with risk of bias and imprecision). The study reported no data for the other primary outcomes. One study compared 20 minutes of intrarectal electromotive botulinum toxin A using 2800 Hz frequency and botulinum toxin A dose 10 international units/kg (n = 30) to 10 international units/kg botulinum toxin A injection (n = 30). We are very uncertain whether intrarectal electromotive botulinum toxin A improves symptom resolution (RR 0.96, 95% CI 0.76 to 1.22; very low certainty evidence) or if it increases the frequency of defecation (mean difference (MD) 0.00, 95% CI -1.87 to 1.87; very low certainty evidence). We are also very uncertain whether intrarectal electromotive botulinum toxin A has an improved safety profile (RR 0.20, 95% CI 0.01 to 4.00; very low certainty evidence). The evidence for these results is of very low certainty due to serious concerns with risk of bias and imprecision. The study did not report data on treatment success. One study compared the injection of 60 units botulinum toxin A (n = 21) to myectomy of the internal anal sphincter (n = 21). We are very uncertain whether botulinum toxin A injection improves treatment success (RR 1.00, 95% CI 0.75 to 1.34; very low certainty evidence). No adverse events were recorded. The study reported no data for the other primary outcomes. One study compared 0.04 mg/kg oral prucalopride (n = 107) once daily to placebo (n = 108) over eight weeks. Oral prucalopride probably results in little or no difference in defecation frequency (MD 0.50, 95% CI -0.06 to 1.06; moderate certainty evidence); treatment success (RR 0.96, 95% CI 0.53 to 1.72; moderate certainty evidence); and adverse events (RR 1.15, 95% CI 0.94 to 1.39; moderate certainty evidence). The study did not report data on symptom resolution. One study compared transcutaneous electrical stimulation to sham stimulation, and another study compared dietitian-prescribed Mediterranean diet with written instructions versus written instructions. These studies did not report any of our predefined primary outcomes. AUTHORS' CONCLUSIONS We identified low to moderate certainty evidence that oral lubiprostone may result in little to no difference in treatment success and adverse events compared to placebo. Based on moderate certainty evidence, there is probably little or no difference between oral prucalopride and placebo in defecation frequency, treatment success, or adverse events. For all other comparisons, the certainty of the evidence for our predefined primary outcomes is very low due to serious concerns with study limitations and imprecision. Consequently, no robust conclusions could be drawn.

Abstract
OBJECTIVE Assess the effectiveness of sacral neuromodulation (SNM) versus personalized conservative treatment (PCT) in patients with refractory idiopathic slow-transit constipation (STC). BACKGROUND Evidence on SNM for idiopathic STC is conflicting and of suboptimal methodological quality. METHODS The No.2-Trial was a multicenter, open-label, pragmatic, randomized trial performed in 2 Dutch hospitals. Sixty-seven patients with idiopathic STC, a defecation frequency <3 per week and refractory (ie, unresponsive) to maximal conservative (nonoperative) treatment were included. Exclusion criteria included outlet obstruction, rectal prolapse, and previous colon surgery. Patients were randomized (3:2) to SNM (n=41) or PCT (n=26) with randomization minimization between February 21, 2017 and March 12, 2020. In SNM patients, an implantable pulse generator was implanted after a successful 4-week test stimulation. PCT patients received conservative treatment such as laxatives or retrograde colonic irrigation. The primary outcome was treatment success (defined as average defecation frequency ≥3 per week) after 6 months. Secondary outcomes included constipation severity, fatigue, quality of life, and adverse events. Analysis was according to intention-to-treat. RESULTS After 6 months, 22 (53.7%) patients were successfully treated with SNM versus 1 (3.8%) patient with PCT (odds ratio 36.4, 95% CI 3.4-387.5, P =0.003). At 6 months, SNM patients reported lower constipation severity and fatigue scores ( P <0.001) and improved quality of life compared with PCT ( P <0.001). Eight serious adverse events (6 SNM, 2 PCT) and 78 adverse events (68 SNM, 10 PCT) were reported. CONCLUSIONS SNM is a promising surgical treatment option in a homogeneous group of adults and adolescents with refractory idiopathic STC. No.2-Trial registered at ClinicalTrials.gov NCT02961582.

Abstract
Background Up to 30% of children have constipation at some stage in their life. Although often short-lived, in one-third of children it progresses to chronic functional constipation, potentially with overflow incontinence. Optimal management strategies remain unclear. Objective To determine the most effective interventions, and combinations and sequences of interventions, for childhood chronic functional constipation, and understand how they can best be implemented. Methods Key stakeholders, comprising two parents of children with chronic functional constipation, two adults who experienced childhood chronic functional constipation and four health professional/continence experts, contributed throughout the research. We conducted pragmatic mixed-method reviews. For all reviews, included studies focused on any interventions/strategies, delivered in any setting, to improve any outcomes in children (0-18 years) with a clinical diagnosis of chronic functional constipation (excluding studies of diagnosis/assessment) included. Dual reviewers applied inclusion criteria and assessed risk of bias. One reviewer extracted data, checked by a second reviewer. Scoping review: We systematically searched electronic databases (including Medical Literature Analysis and Retrieval System Online, Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature) (January 2011 to March 2020) and grey literature, including studies (any design) reporting any intervention/strategy. Data were coded, tabulated and mapped. Research quality was not evaluated. Systematic reviews of the evidence of effectiveness: For each different intervention, we included existing systematic reviews judged to be low risk of bias (using the Risk of Bias Assessment Tool for Systematic Reviews), updating any meta-analyses with new randomised controlled trials. Where there was no existing low risk of bias systematic reviews, we included randomised controlled trials and other primary studies. The risk of bias was judged using design-specific tools. Evidence was synthesised narratively, and a process of considered judgement was used to judge certainty in the evidence as high, moderate, low, very low or insufficient evidence. Economic synthesis: Included studies (any design, English-language) detailed intervention-related costs. Studies were categorised as cost-consequence, cost-effectiveness, cost-utility or cost-benefit, and reporting quality evaluated using the consensus health economic criteria checklist. Systematic review of implementation factors: Included studies reported data relating to implementation barriers or facilitators. Using a best-fit framework synthesis approach, factors were synthesised around the consolidated framework for implementation research domains. Results Stakeholders prioritised outcomes, developed a model which informed evidence synthesis and identified evidence gaps. Scoping review 651 studies, including 190 randomised controlled trials and 236 primary studies, conservatively reported 48 interventions/intervention combinations. Effectiveness systematic reviews studies explored service delivery models (n = 15); interventions delivered by families/carers (n = 32), wider children's workforce (n = 21), continence teams (n = 31) and specialist consultant-led teams (n = 42); complementary therapies (n = 15); and psychosocial interventions (n = 4). One intervention (probiotics) had moderate-quality evidence; all others had low to very-low-quality evidence. Thirty-one studies reported evidence relating to cost or resource use; data were insufficient to support generalisable conclusions. One hundred and six studies described implementation barriers and facilitators. Conclusions Management of childhood chronic functional constipation is complex. The available evidence remains limited, with small, poorly conducted and reported studies. Many evidence gaps were identified. Treatment recommendations within current clinical guidelines remain largely unchanged, but there is a need for research to move away from considering effectiveness of single interventions. Clinical care and future studies must consider the individual characteristics of children. Study registration This study is registered as PROSPERO CRD42019159008.

Abstract
Most children with functional constipation (FC) improve with conventional treatments. However, a proportion of children have poor treatment outcomes. Management of intractable FC may include botulinum toxin injections, transanal irrigation, antegrade enemas, colonic resections, and in some cases sacral nerve stimulation (SNS). SNS is surgically placed, not readily available and expensive. Posterior tibial nerve stimulation (PTNS) allows transmission of electronic impulses and retrograde stimulation to the sacral nerve plexus in a portable, simple and non-invasive fashion. To assess the efficacy and safety of transcutaneous PTNS for the treatment of FC in children. Single-center, prospective interventional study. Children 4-14 years with Rome IV diagnosis of FC received ten daily PTNS (30 min/day) sessions. Electrodes placed over skin of ankle. Strength of stimulus was below pain threshold. Outcomes were assessed during treatment and 7 days after. Twenty-three subjects enrolled. Two children excluded (acute gastroenteritis, COVID-19 contact). Twenty completed the study (4-14 years), (8.4 ± 3.2 years, 71.4% female). We found significant improvement in the consistency of bowel movements (BM) (p = 0.005), fecal incontinence (FI) (p = 0.005), abdominal pain presence (p = < 0.001) and intensity (p = 0.005), and a significant for improvement in blood in stools (p = 0.037). There was 86.3% improvement in abdominal pain. 96.7% reported treatment satisfaction. Only one child required rescue therapy. CONCLUSION We found significant improvement in stool consistency, FI, abdominal pain, and hematochezia. This suggests that transcutaneous PTNS could be a promising noninvasive treatment for FC in children. Large studies are needed. WHAT IS KNOWN • Functional constipation is one of the most common disorders in children. • Current management of functional constipation consists of an integrative approach that includes medications, diet and behavioral strategies. WHAT IS NEW • Posterior tibial nerve stimulation is a novel noninvasive and easy to use therapy that can improve stool consistency, fecal incontinence and blood in stools.

Abstract
OBJECTIVE To explore the effect of stapled trans-anal rectal resection (STARR) on constipation symptoms and inflammatory reaction in patients with outlet obstructive constipation (OOC). METHODS From January 2019 to June 2020, a retrospective analysis was conducted on the medical data of 124 patients with OOC admitted to our hospital. According to the different surgical methods, sixty patients were assigned to the control group (CG) treated with Bresler operation, and sixty-four patients were included in the research group (RG) receiving STARR. The total effective rate of treatment, the incidence of postoperative complications, and mid- and long-term recurrence rate were observed between the two groups. The anorectal dynamic indexes, the constipation scoring system (CSS), obstructive defecation syndrome (ODS), visual analogue scale (VAS) scores, and the changes of inflammatory cytokine [tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)] were compared between the two groups, and the perioperative indexes were observed. RESULTS After operation, a remarkably higher total effective rate was observed in the RG as compared to the CG. The RG obtained lower results in terms of the incidence of postoperative complications, 3-year recurrence rate, operation cost, and intraoperative blood loss than CG. Compared with patients in the CG, those in the RG had shorter operation time, first exhaust time, time of leaving bed, and hospitalization time. Moreover, a shorter defecation time of patients in the RG was also obtained 14 days after treatment. In addition to rectal rest pressure that was similar between the two groups, the anal maximal contraction pressure, anal longest contraction time, anorectal relaxation pressure, and anal rest pressure were significantly higher in the RG than in the CG. After operation, remarkably lower CSS and ODS scores of patients were obtained in the RG than in the CG. The RG yielded lower VAS scores after operation and 24 hours after operation, and lower levels of TNF-α and IL-6 1 day after operation in contrast to the CG. CONCLUSION STARR can effectively improve the clinical efficacy, ameliorate the symptoms of postoperative constipation, reduce the long-term recurrence rate, relieve postoperative pain, and better protect the anorectal function and mitigate inflammatory reaction for patients with obstructive constipation.

Abstract
BACKGROUND The aim of the present study was to compare sacral nerve stimulation (SNS) for constipation (SNS-C) with SNS for idiopathic faecal incontinence (SNS-IFI) regarding explantation rate, additional visits, and improvement of patient satisfaction 5 years after implantation. METHODS From our prospective database (launched in 2009), we extracted all SNS-C patients 5 years post-implantation, and the SNS-IFI patients implanted just before and just after each SNS-C patient. We retrospectively evaluated the explantation rate, number of additional visits, and patient satisfaction using a visual analogue scale (VAS). We hypothesized that compared with those in the SNS-IFI group: (1) the explantation rate would be higher in SNS-C patients, (2) the number of additional visits would be higher in SNS-C patients, and (3) in patients with an active implant at 5 years, the improvement in VAS would be the same. RESULTS We included 40 SNS-C patients and 80 SNS-IFI patients. In the SNS-C group 7/40 (17.5%), patients were explanted, compared to 10/80 (12.5%) patients in the SNS-IFI group (p = 0.56). The mean number of additional visits in the SNS-C group was 3.5 (95% CI 2.8-4.1)) and 3.0 (95% CI 2.6-3.6)) in the SNS-IFI group (p = 0.38). Additional visits due to loss of efficacy were significantly higher in the SNS-C patients (p = 0.03). The reduction in VAS score (delta VAS) at 5 years was 37.1 (95% CI 20.9-53.3) in the SNS-C group, and 46.0 (95% CI 37.9-54.0) in the SNS-IFI group (p = 0.27). CONCLUSIONS No significant difference was found regarding explantation rate, number of additional visits, or improvement of VAS at 5 years after SNS implantation between SNS-C patients and SNS-IFI patients.

Abstract
BACKGROUND There has been some controversy regarding the efficacy of sacral nerve stimulation (SNS) for the treatment of chronic constipation, due to less positive outcomes and concerns about cost-effectiveness in the long term. The aim of the present study was to evaluate the long-term outcomes of SNS in patients with chronic constipation. METHODS A retrospective study was conducted on patients who had SNS for chronic constipation in 2008-2017 at our institution. Clinical factors, profile of constipation, physiology studies, and patient satisfaction with SNS therapy were investigated during a follow-up period up to 10 years after the implantation. RESULTS Twenty-nine patients [86% female, median age 49 years (range 17-86)] were tested for SNS, and 24 received implants after a positive test phase [median 47 days (range 21-56 days)]. There were 27 bilateral and 2 unilateral implants, in S3 or S4 depending on best response. Mean follow-up was 59 months. Efficacy was considered as a score > 5 (on a scale of 1-10) in general symptom improvement. Nine (37.9%) implanted patients had a satisfaction score > 5. In 6 cases (25%), patient satisfaction was higher than 9. Due to the small sample size, there were no statistically significant variables considered as predictors of response. CONCLUSIONS Our results agree with current studies which describe around a 30% response of SNS for refractory constipation. However, there is a small group of patients highly satisfied with SNS therapy. More studies are needed to better understand this profile and optimize outcomes.
