Transanal proximal rectosigmoidectomy: a single-center experience in surgically treated severe medically refractory idiopathic constipation.

PURPOSE: To present the functional results after a transanal proximal rectosigmoidectomy in patients with severe idiopathic constipation in which medical treatment has failed. METHODS: Patients with severe idiopathic constipation who underwent transanal proximal rectosigmoidectomy (TPRS) at Children's Hospital Colorado between June 2019 and March 2024 were included in the study. We compared multiple pre- and post-operative outcome measures and the patient's bowel regimen before and after resection. RESULTS: Fourteen patients underwent TPRS, 10 of whom were male. The average age at the time of surgery was 10.1 years (range 5-19). Seven patients have moderate to severe autism. Constipation-related clinic visits, family calls, procedural intervention, emergency room visits, and hospitalizations notably decreased frequency after TPRS. Laxative dosages and enema volume requirements were also reduced after surgery. Before surgery, all the patients suffered from daily fecal accidents, while post-operatively, all were completely free of stool accidents. CONCLUSION: In our experience, for patients who suffer from severe medically refractory idiopathic constipation, TPRS has provided improvement in their symptoms and decreased the complications inherent to this chronic disease. Parents and patients attest to a profound positive transformation in their quality of life after surgery.

Predictors of medical adherence following a bowel management program for youth and young adults with Spina Bifida.

PURPOSE: To evaluate individual and community sociodemographic factors that predict bowel regimen adherence in youth and young adults with Spina Bifida (SB) following participation in a bowel management program (BMP). METHODS: Participants were drawn from clinical cases seen through an International Center for Colorectal and Urogenital Care. Area deprivation index (ADI) scores were extracted from participant addresses and bowel regimen adherence data were collected from the electronic medical record (EMR). RESULTS: Participants' mean age was 8.06 years old, 51.7% were male, 72.4% white, 37.9% Hispanic, 56.9% government insurance, 89.7% myelomeningocele, 15.5% non-adherent. Average neighborhood disadvantage was 5.19 (SD:2.83, range:1-10). After controlling for variables correlated with adherence (p < .20), every one decile higher neighborhood disadvantage score was associated with a 48% decrease in the odds of being adherent (OR = 0.52, p = .005, 95% CI: - 101.90, - 0.21). CONCLUSION: Our results suggest that neighborhood disadvantage is a strong predictor of medical adherence following a BMP, more so than other sociodemographic and health-related variables. These results may assist with identifying which individuals may be at higher risk for poor health outcomes due to neighborhood socioeconomic disadvantage and help health care systems intervene proactively.

Urological outcomes in adult females born with anorectal malformation or Hirschsprung disease.

INTRODUCTION: Women born with anorectal malformation (ARM) or Hirschsprung disease (HD) may have impaired urologic function resulting in sequelae in adulthood. This study assessed and compared self-reported urinary outcomes in adult females born with ARM or HD to a reference population. METHODS: This was an IRB approved, cross-sectional study of female-born patients with ARM or HD, who completed surveys between November 2021 and August 2022. Female patients between the ages of 18 and 80 years were included. Lower Urinary Tract Symptom Questionnaires were administered through REDCap and the responses were compared to a reference population using Chi-squared or Fisher's exact tests. RESULTS: Sixty-six born female patients answered the questionnaires, two of them identified as non-binary. The response rate was 76%. Median age was 31.6 years. The majority were born with cloaca (56.3%), followed by other type of ARMs (28.1%), complex malformation (9.4%), and HD (6.3%). A history of bladder reconstruction was present for 26.6%. Catheterization through a channel or native urethra was present in 18.8%. Two had ureterostomies and were excluded from the analysis. Seven had chronic kidney disease or end-stage renal disease, three with a history of kidney transplantation. Patients with cloaca had significantly higher rates of urinary incontinence, urinary tract infection, and social problems due to impaired urological functioning, when compared to an age-matched reference population (Table 3). CONCLUSION: This study emphasizes the need for a multi-disciplinary team that includes urology and nephrology following patients with ARM long term, especially within the subgroup of cloaca. LEVEL OF EVIDENCE: III.

Identifying predictive factors for bowel control in patients with spina bifida and spinal cord injuries.

PURPOSE: This study aimed to assess our bowel management program (BMP) and identify predictive factors for bowel control in patients with Spina Bifida (SB) and Spinal Cord Injuries (SCI). Additionally, in patients with SB, we examined the impact of fetal repair (FRG) on bowel control. METHODS: We included all patients with SB and SCI seen in the Multidisciplinary Spinal Defects Clinic at Children's Hospital Colorado from 2020 to 2023. RESULTS: 336 patients included. Fecal incontinence was present in 70% and bowel control in 30%. All patients with urinary control also had bowel control. Fecal incontinence prevalence was higher in patients with ventriculoperitoneal (VP) shunt (84%), urinary incontinence (82%), and wheelchair users (79%) compared to those who did not need a VP shunt (56%), had urinary continence (0%) and non-wheelchair users (52%), respectively (p = < 0.001 in all three scenarios). After completing BMP, 90% remained clean for stool. There was no statistical significance when comparing bowel control in FRG with non-fetal repair group. CONCLUSIONS: Urinary continence predicts bowel control in patients with SB and SCI. Risk factors for fecal incontinence were the need for a VP shunt, urinary incontinence, and wheelchair usage. We did not find any positive impact of fetal repair on bowel and urinary control.

Gastrointestinal quality of life and bowel function in adults born with anorectal malformation and hirschsprung disease.

PURPOSE: To assess the quality of life and disease-specific functioning of adults with anorectal malformations (ARM) or Hirschsprung disease (HD) compared to healthy reference scores. METHODS: Patients with the diagnosis of ARM or HD from the Adult Colorectal Research Registry completed the Short Form 36 Health Survey (SF-36), the Gastrointestinal Quality of Life Index (GIQoLI), and the Bowel Function Score (BFS) between October 2019 and August 2022. One-sample Wilcoxon test compared the results to reported healthy references with a significance level of < 0.05. RESULTS: The response rate was 67%. All three surveys were completed by 133 adults with a slight preponderance of males (51%). Median age was 31 years, 117 were born with ARM and 16 with HD. All subgroups had significantly lower BFS than healthy references. ARM patients scored significantly lower than the healthy reference population when assessed for GIQoL. All showed significant impairment with the mental component summary (MCS) of SF-36. Patients with a successful bowel management had significantly higher scores on all three questionnaires than those with fecal accidents. CONCLUSION: Our results emphasize the importance of a successful bowel management and its impact on the quality of life and bowel function. Long-term follow-up is recommended with attention to mental health.

Radiologically supervised bowel management program outcome in patients with chronic idiopathic constipation.

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.

Fertility concerns and outcomes in females with anorectal malformations.

PURPOSE: To assess fertility concerns and to describe pregnancy outcomes in patients with anorectal malformations (ARM). METHODS: This is an IRB approved, cross-sectional study of patients in the Adult Colorectal Research Registry who completed reproductive health surveys between November 2021 and August 2022. Patients assigned female at birth with age 18 or older and ARM were included. RESULTS: Sixty-four patients with ARM, age 18 or older, were included. Fertility concerns were reported in 26 (40.6%) patients, 11 of which had seen a fertility specialist, including four who had not yet tried to conceive. Fertility concerns were highest amongst cloaca patients who had not yet tried to conceive (37.5%). 26 (40.6%) patients had tried to conceive, of which 16 (25%) reported fertility problems, most frequently uterine abnormalities and damaged or blocked fallopian tubes. 22 (34.4%) participants were able to conceive and 18 (28.1%) had at least one live birth. Patients with ARM who had concerns of fertility, had better FertiQoL when compared to published reference scores for patients experiencing fertility issues. CONCLUSION: Providers should be aware of fertility concerns in patients with ARM. Proactive counseling with referrals to a fertility specialist should be considered in patients who desire future fertility.

Stricture rate in patients after the repair of anorectal malformation following a standardized dilation protocol.

PURPOSE: The aim of this study was to determine and analyze the stricture rate in patients who underwent a PSARP or PSARVUP and followed a postoperative protocol of anal dilation (Fig. 1). METHODS: A retrospective review of patients with anorectal malformation (ARM) who underwent a primary PSARP or PSARVUP from February 2016 to October 2021 was performed. Data collected included patients' demographics, type of ARM, age at the time of operation, postoperative complications, with emphasis on whether there were any strictures or any difficulties during dilations, and on follow-up. During the surgical repair, emphasis was placed on preserving the blood supply of the bowel and performing a tension-free bowel-to-skin anastomosis. RESULTS: Eighty-four patients met the inclusion criteria. Forty-four patients were females: 21 recto-perineal fistula, 12 cloaca, 9 recto-vestibular fistula, one imperforate anus without fistula, and one patient had a complex anorectal and vaginal malformation with an anal stricture and a rectovaginal fistula. Forty patients were males: 14 recto-perineal fistula, 11 recto-urethral bulbar fistula, 6 recto-urethral prostatic fistula, 6 imperforate anus without fistula, and 2 bladder neck fistula. One patient had an anal stenosis with sacral agenesis, without a presacral mass. Patient ages ranged from 0 to 79 months (mean 7.5 months, median 5 months) at the time of surgery. Follow-up time ranged from 7 to 73 months (mean 38 months, median 35 months). No patient suffered of a postoperative anal stricture. Six patients suffered of a rectal prolapse that required a surgical repair. CONCLUSION: Post-operative anal stricture after PSARP and PSARVUP can be avoided with proper surgical technique and postoperative care. Namely, by preserving adequate blood supply of the bowel and avoiding tension at the anoplasty, and by adhering to a structured protocol of anal dilations.

Considering the value of online support groups for colorectal conditions: perspectives from caregivers and adult patients.

PURPOSE: To evaluate the benefits of participating in an online support group for caregivers of children with a colorectal condition or adult patients with a similar condition. METHODS: An electronic survey was administered to members of an international online support group (18 items for caregivers; 15 for patients). Items included demographics, medical diagnosis, potential benefits, and overall experiences in the group. Quantitative results were summarized as descriptive trends, while qualitative responses were summarized thematically. RESULTS: Respondents (102 caregivers, 6 patients) were primarily female, 35-44 years old, Caucasian, and resided in the United States. Most respondents learned about the support group from medical providers or online search. Cited benefits included learning information, gaining support, forming connections through shared experience, and utilizing a unique resource. Being a member of the group was helpful to respondents, improved their mental health and access to health information, and they would recommend the group to others. CONCLUSION: Participation in online support groups offers educational and emotional benefits to patients/caregivers which complements the medical support from their colorectal teams. Thus, colorectal providers need to be aware of the availability and potential benefits of these groups, and encourage their patients/caregivers to be actively involved.

Is the appendix a good organ to diagnose total colonic aganglionosis?

PURPOSE: The use of the appendix for diagnosis of Total Colonic Aganglionosis (TCA) remains controversial. This study aimed to categorize the presence of ganglion cells in the appendix and determine its reliability as a histological specimen for the diagnosis of TCA. METHODS: This was a combined retrospective and prospective study. Permanent histological specimens of normal appendices removed during appendectomy for malrotation or falsely presumed appendicitis, and from patients with short segment Hirschsprung's disease (HD) or TCA were included. Permanent specimens of the appendix tip from Malone procedures were prospectively collected. All specimens were independently reviewed by two experienced pathologists in a standardized manner to assess for the presence of ganglion cells. RESULTS: A total of 112 appendices were evaluated. Nine came from patients with a diagnosis of TCA, and five from patients with HD. Ganglion cells were present in all specimens from patients with diagnoses other than TCA and were absent in all specimens from patients with TCA. CONCLUSION: In the correct clinical setting, the absence of ganglion cells in the appendix can allow for a reliable diagnosis of TCA.
