Abstract
Constipation is a common childhood problem, but an anatomic or physiologic cause is identified in fewer than 5% of children. By definition, idiopathic constipation is a diagnosis of exclusion. Careful clinical evaluation and thoughtful use of imaging and other testing can help exclude specific causes of constipation and guide therapy. Medical management with laxatives is effective for the majority of constipated children. For those patients unresponsive to medications, however, several surgical options can be employed, including anal procedures, antegrade colonic enemas, colorectal resection, and intestinal diversion. Judicious use of these procedures in properly selected patients and based on appropriate preoperative testing can lead to excellent outcomes. This review summarizes the surgical options available for managing refractory constipation in children and provides guidance on how to choose the best procedure for a given patient.

Abstract
Implantable functional electrical stimulation (IFES) has demonstrated its effectiveness as an alternative treatment option for diseases incurable pharmaceutically (e.g., retinal prosthesis, cochlear implant, spinal cord implant for pain relief). However, the development of IFES for gastrointestinal (GI) tract modulation is still limited due to the poorly understood GI neural network (gut⁻brain axis) and the fundamental difference among activating/monitoring smooth muscles, skeletal muscles and neurons. This inevitably imposes different design specifications for GI implants. This paper thus addresses the design requirements for an implant to treat GI dysmotility and presents a miniaturized wireless implant capable of modulating and recording GI motility. This implant incorporates a custom-made system-on-a-chip (SoC) and a heterogeneous system-in-a-package (SiP) for device miniaturization and integration. An in vivo experiment using both rodent and porcine models is further conducted to validate the effectiveness of the implant.

Abstract
PURPOSE OF REVIEW Constipation is a very common problem in pediatrics with both the severity of presentations and treatments varying across a broad spectrum. The majority of children with functional constipation are managed successfully without the need for specialized testing and surgical intervention. Those who present with intractable constipation, with or without fecal soiling, require referrals for motility testing that helps determine both medical and surgical management, and interventions. The literature was reviewed for publications on surgical approaches to children with severe constipation, including assessing the quality and levels of evidence and the use of objective measures to determine outcomes. RECENT FINDINGS There is very little in the way of recent studies evaluating surgical indications or treatment approaches for functional constipation, apart from one systematic review and one recent expert review. Although the systematic review was published in the last year, most of the studies it analyzes are older. The vast majority of studies comprise level 4 and 5 evidence. SUMMARY The indication for most surgical procedures is 'failed' medical management, yet no standardized definition for this exists. Many surgical procedures are proposed with little evidence to show outcomes. We recommend that the surgical evaluation and treatment of children with constipation needs to be protocolized and studied in a prospective manner using validated outcomes measures. Our center's current protocol is described.

Abstract
The prevalence of functional constipation in children is almost 10%. The etiology is multifactorial and not fully understood. In the majority of cases, there is no organic explanation for the symptoms. However, it is very important to exclude organic causes, particularly in neonates and infants. There are warning symptoms, such as delayed passage of meconium, bilious vomiting and abdominal distention that should prompt further investigations. Fecal incontinence is a very common symptom secondary to fecal impaction. The first-line treatment for both disimpaction and maintenance is use of laxatives. Parental education is extremely important. There are very limited data on surgical approaches for functional constipation.

Abstract
BACKGROUND Antegrade continence enema (ACE) is a recognized therapeutic option in the management of pediatric refractory constipation. Data on the long-term outcome of patients who fail to improve after an ACE-procedure are lacking. PURPOSE To describe the rate of ACE bowel management failure in pediatric refractory constipation, and the management and long term outcome of these patients. METHODS Retrospective analysis of a cohort of patients that underwent ACE-procedure and had at least 3-year-follow-up. Detailed analysis of subsequent treatment and outcome of those patients with a poor functional outcome was performed. RESULTS 76 patients were included. 12 (16%) failed successful bowel management after ACE requiring additional intervention. Mean follow-up was 66.3 (range 35-95 months) after ACE-procedure. Colonic motility studies demonstrated colonic neuropathy in 7 patients (58%); abnormal motility in 4 patients (33%), and abnormal left-sided colonic motility in 1 patient (9%). All 12 patients were ultimately treated surgically. Nine patients (75%) had marked clinical improvement, whereas 3 patients (25%) continued to have poor function issues at long term follow-up. CONCLUSIONS Colonic resection, either segmental or total, led to improvement or resolution of symptoms in the majority of patients who failed cecostomy. However, this is a complex and heterogeneous group and some patients will have continued issues.

Abstract
Constipation is a common problem in children. It is also a long-term problem persisting for many months to years in children. Approximately 95% of childhood constipation is functional in nature without any obvious cause. Evaluation of a child with constipation requires a thorough history and physical examination. Hirschsprung's disease is an important cause of constipation arising in infancy and requires a thorough diagnostic evaluation and surgical treatment. Treatment of functional constipation in children requires a well-designed plan and a team approach involving the child, parents, and a health care provider. Treatment involves education of the family about constipation and encopresis, fecal disimpaction, and long-term maintenance therapy of laxatives and behavioral modification. Laxatives such as magnesium hydroxide, lactulose, and mineral oil have been used in children for a long time. A new laxative, polyethylene glycol 3350, has been used successfully in children with constipation and encopresis. Several novel therapeutic interventions have been tried for children presenting with intractable constipation, refractory to conventional treatment.

Abstract
PURPOSE Intractable constipation in children is an uncommon but debilitating condition. When medical therapy fails, surgery is warranted; but the optimal surgical approach has not been clearly defined. We reviewed our experience with operative management of intractable constipation to identify predictors of success and to compare outcomes after 3 surgical approaches: antegrade continence enema (ACE), enteral diversion, and primary resection. METHODS A retrospective review of pediatric patients undergoing ACE, diversion, or resection for intractable, idiopathic constipation from 1994 to 2007 was performed. Satisfactory outcome was defined as minimal fecal soiling and passage of stool at least every other day (ACE, resection) or functional enterostomy without abdominal distension (diversion). RESULTS Forty-four patients (range = 1-26 years, mean = 9 years) were included. Sixteen patients underwent ACE, 19 underwent primary diversion (5 ileostomy, 14 colostomy), and 9 had primary colonic resections. Satisfactory outcomes were achieved in 63%, 95%, and 22%, respectively. Of the 19 patients diverted, 14 had intestinal continuity reestablished at a mean of 27 months postdiversion, with all of these having a satisfactory outcome at an average follow-up of 56 months. Five patients underwent closure of the enterostomy without resection, whereas the remainder underwent resection of dysmotile colon based on preoperative colonic manometry studies. Of those undergoing ACE procedures, age younger than 12 years was a predictor of success, whereas preoperative colonic manometry was not predictive of outcome. Second manometry 1 year post-ACE showed improvement in all patients tested. On retrospective review, patient noncompliance contributed to ACE failure. CONCLUSIONS Antegrade continence enema and enteral diversion are very effective initial procedures in the management of intractable constipation. Greater than 90% of diverted patients have an excellent outcome after the eventual restoration of intestinal continuity. Colon resection should not be offered as initial therapy, as it is associated with nearly 80% failure rate and the frequent need for additional surgery.

Abstract
A descriptive review of 12 patients who underwent appendicocecostomy or caecostomy for antegrade colonic lavage from January 2002 to February 2008. There were 9 appendicocecostomies performed patients from 3 to 13 years suffering from myelomeningocele, of which 8 of them had a very good outcome, with one case withdrawn due to poor use by the family. Three caecostomies were performed in non-mentally retarded constipated children. One was an otherwise healthy 7 year-old boy with hard stools since he was 10 months old, in spite of multiple laxative treatments, with normal morphology and function. He had a percutaneous caecostomy five years ago, with some improvement and a good quality of life, but still some occasional partial impactions. Another healthy 12 year-old boy with daily constipation associated faecal incontinence since he was 3 years old (normal manometry and rectal biopsy with signs of mild neuronal dysplasia) had a percutaneous caecostomy performed three years ago, with improvement in the faecal incontinence and better psychological outcome. The last caecostomy patient was an 8-year-old boy, with a similar clinical history and good progress in last three years after placing a Chait's button using an endoscopic procedure. Stubborn constipation continuing into adult life has a negative impact on the social and emotional adaptation of the paediatric patient, affecting family interactions. Antegrade colonic lavage allows independence and improves the quality of life in patients affected by recurrent faecal impactions. This technique needs to be performed on more patients to find out its true effectiveness.

Abstract
PURPOSE Idiopathic chronic childhood constipation (ICCC) includes children who are severely constipated and who are resistant to behavioral or medical treatments. These children are distinguished from those with Hirschsprung's disease (HSCR) by the presence of enteric ganglia in rectal biopsy specimens. We investigated potential autonomic dysfunction by examining nerves in rectal mucosa. METHODS Immunostaining, confocal microscopy, and nerve analysis were performed on formalin-fixed and on Zamboni-fixed rectal biopsy specimens from children who were severely constipated. A computer-assisted neuron tracing technique was used to determine mucosal nerve density in Zamboni-fixed biopsy sections. RESULTS Nerves in Zamboni-fixed biopsy specimens were better stained than in formalin-fixed biopsy specimens. Regardless of fixation method, a deficiency of mucosal nerves was observed in ICCC when compared to children who are not constipated. Analysis of autotraced mucosal nerves confirmed the deficiency in ICCC biopsy specimens. Mucosal nerves were also severely deficient in patients with HSCR, even in transitional segments that contained ganglia. CONCLUSIONS Most patients with ICCC had decreased innervation of the rectal mucosa. Because mucosal nerves are critical for the peristaltic reflex, water secretion, and absorption, their deficiency can be related to patient constipation. Mucosal nerve density provides a pathologic basis for diagnosis of dysfunction in children who do not have HSCR but are chronically constipated. The study validates the neuron tracing method for objective evaluation of mucosal innervation.

Abstract
Patients with constipation and fecal incontinence usually come to the attention of the surgeon when conservative measures have failed to alleviate sufficiently severe symptoms. Following detailed clinical and physiologic assessment, the surgeon should tailor the procedure to specific underlying physiologic abnormalities to restore function. This article describes the rationale, indications (including patient selection), results, and current position controversies of surgical procedures for constipation and fecal incontinence, dividing these into those regarded as historical, contemporary, or evolving. Reported surgical outcome data must be interpreted with caution because for most studies the evidence is of low quality, making comparison of different procedures problematic and emphasizing the need for better designed and conducted clinical trials.
