Abstract
PURPOSE This study aimed to analyze our radiologically supervised bowel management program (RS-BMP) outcomes in patients with chronic idiopathic constipation (CIC). METHODS A retrospective study was conducted. We included all patients with CIC who participated in our RS-BMP at Children´s Hospital Colorado from July 2016 to October 2022. RESULTS Eighty patients were included. The average time with constipation was 5.6 years. Before our RS-BMP, 95% had received non-radiologically supervised treatments, and 71% had attempted two or more treatments. Overall, 90% had tried Polyethylene Glycol and 43% Senna. Nine patients had a history of Botox injections. Five underwent anterograde continence procedure, and one a sigmoidectomy. Behavioral disorders (BD) were found in 23%. At the end of the RS-BMP, 96% of patients had successful outcomes, 73% were on Senna, and 27% were on enemas. Megarectum was detected in 93% of patients with successful outcomes and 100% with unsuccessful outcomes (p = 0.210). Of the patients with BD, 89% had successful outcomes, and 11% had unsuccessful. CONCLUSION Our RS-BMP has been proven to be effective in treating CIC. The radiologically supervised use of Senna and enemas was the appropriate treatment in 96% of the patients. BD and megarectum were associated with unsuccessful outcomes.

Abstract
OBJECTIVE This study aims to discuss the treatment of congenital recto-vestibular fistula and recto-perineal fistula, and the effect of the megarectum on defecation. BACKGROUND Congenital recto-vestibular fistula or recto-perineal fistula is the most common type of anorectal malformation, and surgical methods include posterior sagittal anorectoplasty, anterior sagittal anorectoplasty, and mid-sagittal anorectoplasty, which can be performed at stage one or stage two after the ostomy. In the later stages of a recto-vestibular fistula, constipation is a common complication. Rectal dilatation is frequently associated with constipation, and the effect of rectal dilatation on defecation should be discussed for patients with congenital recto-vestibular or recto-perineal fistula who had rectal dilatation prior to surgery. Rectal dilatation may be one of the causes of constipation for congenital recto-vestibular fistula and recto-perineal fistula. METHODS The patients in this study were 67 children with congenital recto-vestibular fistula or recto-perineal fistula treated in our hospital from March 2013 to February 2017. All patients underwent an MRI of the spine and a barium enema. Six patients with myelodysplasia and sacral agenesis were excluded from this study. There were 18 patients with rectal dilatation (ages: 4-month-old to 1 year old, male: 3, female: 15). Seven of them had anterior sagittal anorectoplasty (group A), and 11 had anorectoplasty with dilated rectum resection (group B). Forty-three patients (ages: 3- to 10 months old, male: 6; female: 37) without a dilated rectum underwent anterior sagittal anorectoplasty (group C). RESULTS All patients were followed up for 1 year to 5 years. Among the 50 patients who had undergone an anoplasty, 5 out of 7 patients with rectal dilatation developed post-operative constipation, and 3 of them had normal defecation after the second resection of the dilated rectum. Only two out of 43 patients without rectal dilatation developed post-operative constipation. One out of 11 patients with rectal dilatation who underwent anoplasty and resection of the dilated rectum developed post-operative constipation. CONCLUSION Patients with congenital recto-vestibular fistula or recto-perineal fistula complicated by rectal dilatation are more susceptible to post-operative constipation. Resection of the dilated rectum at the same time can reduce the incidence rate of constipation. A barium enema should be performed pre-operatively for patients with congenital recto-vestibular fistula or recto-perineal fistula. If the dilated rectum is found, it can be resected at the same time.

Abstract
BACKGROUND/PURPOSE Congenital megarectum (CMR) is sometimes associated with anorectal malformations (ARM), although there is no established therapeutic strategy. This study aims to clarify the clinical features of ARM with CMR, and to demonstrate the effectiveness of a surgical treatment, namely laparoscopic-assisted total resection and endorectal pull-through technique. METHODS We conducted a review of the clinical records of the patients with ARM with CMR treated at our institution between January 2003 and December 2020. RESULTS Seven of 33 cases of ARM (21.2%) were diagnosed with CMR, four males and three females. The types of ARM were 'intermediate' in four, and 'low' in three patients. Five of the seven patients (71.4%) required resection of megarectum for intractable constipation and underwent laparoscopic-assisted total resection and endorectal pull-through technique. Bowel function was improved after resection in all five cases. All five specimens showed hypertrophy of the circular fibers, and three of them showed abnormal location of ganglion cells within the circular muscle fibers. CONCLUSIONS CMR often causes intractable constipation and requires resection of the dilated rectum. Laparoscopic-assisted total resection and endorectal pull-through technique for ARM with CMR considered to be an effective, minimally invasive treatment for intractable constipation.

Abstract
PURPOSE Megarectum in anorectal malformation (ARM) causes severe morbidity. To compare conservative management (CM) of megarectum with excision (EX), to propose a new classification and to analyse management strategies. METHODS Between 2000-2016, we reviewed all ARM to identify megarectum, defined by radiological recto-pelvic ratio > 0.61. A new classification was proposed: primary megarectum (PM) pre-anorectoplasty, and secondary megarectum (SM) post-anorectoplasty, with sub-types. Complications and Krickenbeck bowel function were compared between CM and EX. RESULTS Of 124 ARM, 22 (18%) developed megarectum; of these, 7 underwent EX. There was no difference in functional outcomes when comparing CM vs EX-voluntary bowel movement (both 86%), soiling (40% vs. 57%) and constipation (both 86%). However, EX was associated with major complications (43%) and the requirement for invasive bowel management, compared to CM (85% vs. 27%, P = 0.02). 6/7 EX needed antegrade continence enema (ACE), one of these has a permanent ileostomy. With strategic changes, incidence of megarectum reduced from 20/77 (26%) to 2/47 (4%) after 2013 (P = 0.002). CONCLUSION EX did not confer benefit in the functional outcome but carried a high risk of complications, often needing ACE or stoma. By adhering to strategies discussed, we reduced the incidence of megarectum and have avoided EX since 2013.

Abstract
Background The role of surgery in treating children with functional constipation (FC) is controversial, because of the efficacy of bowel management programs. This case series is comprised of failures: 43 children, spanning 25 years' practice, who had megarectosigmoid (MRS) and unremitting constipation. Purpose To determine whether these children were helped by surgery, and to contribute to formulating a standard of care for children with megarectum (MR) and/or redundancy of the sigmoid colon (MS) who fail medical management. Method We describe our selection criteria and the procedures we utilized – mucosal proctectomy and endorectal pull-through (MP) or sigmoidectomy (SE) with colorectal anastomosis at the peritoneal reflection. The internet (social media) allowed us to contact most of these patients and obtain extremely long follow-up data. Results 30/43 patients had MP and 13/43 had SE. Follow-up was obtained in 83% MP and 70% SE patients. 60% of MP and 78% of SE patients reported regular evacuations and no soiling. 20% MP patients had occasional urgency or soiling or episodic constipation. 12% MP and 22% SE patients required antegrade continence enemas (ACE) or scheduled cathartics and/or stool softeners. 4% MP had no appreciable benefit, frequent loose stools and soiling, presumably from encopresis. Conclusion MR is characterized by diminished sensation, poor compliance and defective contractility. Patients with MR do better with MP, which effectively removes the entire rectum versus SE, where normal caliber colon is anastomosed to MR at the peritoneal reflection; furthermore, MP reliably preserves continence; whereas total proctectomy (trans-anal or trans-abdominal) may cause incontinence. Intestinal peristalsis stagnates in a dilated segment. Megarectosigmoid (MRS) may present during infancy or later in life. It may occur in association with anorectal malformations or as an isolated abnormality. Unlike dilatation secondary to outlet dysfunction, MRS persists even after a diverting colostomy. MRS does not respond to bowel management programs. Intestinal peristalsis improves following extirpation of MRS.

Abstract
PURPOSE Internal rectal prolapse is common and correlates with age. It causes a plug-like physical obstruction and is a major cause of defecation disorder. The progressive distortion of the prolapsing rectum likely causes secondary defects in the rectal wall, which may exacerbate rectal dysfunction. We undertook a prospective observational study to detect and quantify the neurologic and histopathologic changes in the rectal wall. METHODS We examined dorsal and ventral rectal wall specimens from consecutive patients with internal rectal prolapse undergoing stapled transanal rectal resection (STARR). We subjected specimens to histopathologic and neuropathologic assessment, including immunohistochemistry. We also recorded patients' clinical and demographic characteristics and sought correlations between these and the pathologic findings. RESULTS We examined 100 specimens. The severity of rectal prolapse and the extent of descent of the perineum correlated significantly with age. Concomitant hemorrhoidal prolapse was noted in all male patients and in 79 % of female patients. Muscular and neuronal defects were detected in 94 and 90 % of the specimens, respectively. Only four specimens (4 %) were free of significant structural defects. CONCLUSION Rectal prolapse traumatizes the rectum causing neuromuscular defects. The tissue trauma is due to shearing forces and ischemia caused by the intussusception. This initiates a self-reinforcing vicious circle of physical and functional obstruction, further impairing rectal evacuation and causing constipation and incontinence. The correlation between extent of prolapse and age suggests that internal rectal prolapse can be considered a degenerative disorder. Neural and motor defects in the wall of the rectum caused by rectal prolapse are likely irreversible.

Abstract
BACKGROUND Primary posterior sagittal anorectoplasty is recommended to repair anorectal malformations with rectoperineal or rectovestibular fistula. The aim of this study was to identify the impact of the presence of megarectum on the relative frequency of complications related to posterior sagittal anorectoplasty. METHODS We performed a cross-sectional retrospective study including patients with anorectal malformation, preoperative rectogram and surgically treated with primary or staged posterior sagittal anorectoplasty. Only complications related to anorectoplasty were analyzed and compared with the presence of megarectum. RESULTS Thirty patients aged 1 day to 7 years were included, 60% had megarectum. Sixteen patients had primary repair: 6 with megarectum and 10 without megarectum; complications occurred in four of the six with megarectum, 66.7%, and no complication were observed in the 10 patients without megarectum (F p=0.008). Fourteen patients had staged repair and no complications related to posterior sagittal anorectoplasty occurred in these patients. CONCLUSIONS Comprehensive preoperative evaluation in patients with anorectal malformation with rectoperineal or rectovestibular fistula could include a rectogram. Awareness of the presence of megarectum could be useful information in the decision to create a colostomy or perform a primary posterior sagittal anorectoplasty.

Abstract
AIM: Chronic constipation is a frequent finding in children. In this age range, the concomitant occurrence of megarectum is not uncommon. However, the definition of megarectum is variable, and a few data exist for Italy. We studied anorectal manometric variables and sensation in a group of constipated children with megarectum defined by radiologic criteria. Data from this group were compared with those obtained in a similar group of children with recurrent abdominal pain.
METHODS: Anorectal testing was carried out in both groups by standard manometric technique and rectal balloon expulsion test.
RESULTS: Megarectum patients displayed discrete abnormalities of anorectal variables and sensation with respect to controls. In particular, the pelvic floor function appeared to be impaired in most patients.
CONCLUSION: Constipated children with megarectum have abnormal anorectal function and sensation. These findings may be helpful for a better understanding of the pathophysiological basis of this condition.
