Bridging the Gap: The Impact of Bowel Management Programs on Daily Life in Pediatric Colorectal Disease.

BACKGROUND: This commentary discusses the social impact of bowel management programs (BMPs) on children with colorectal diseases, including anorectal malformations (ARM), Hirschsprung disease (HD), functional constipation (FC), and spina bifida. Previous studies focused on functional outcomes, but this study bridges the gap to daily life experiences. METHODS: The study examined children's experiences in BMPs, focusing on school participation, vacation ability, and overall patient experience. Cleanliness, defined as fewer than one stool soiling episode per week, was achieved by 70% of participants. RESULTS: Positive patient experiences were linked to achieving stool cleanliness, regardless of the management method. Invasive methods like enemas did not negatively affect experiences if cleanliness was maintained. Validated patient-reported experience measures (PREMs) and patient-reported outcomes measures (PROMs) were used, though the median age of 8.9 years posed limitations. CONCLUSION: The commentary highlights the significance of stool cleanliness in improving patient experiences and supports the effectiveness of various BMP methods. Future research should include longitudinal follow-ups to assess BMP durability and gather data from older children.

Qualitative inductive analysis of the lives of women with persistent cloaca based on their narratives.

PURPOSE: The study aimed to explore and describe the lives of patients with persistent cloaca (PC) from childhood to adulthood. METHODS: Semistructured interviews were conducted with nine adult patients with PC. Their experiences and thoughts regarding this disease were analyzed qualitatively and inductively. RESULTS: After classifying the experiences and thoughts of patients with PC, 13 categories were extracted. The following five themes emerged from these categories. (1) Difficulties with excretion and vaginal management because of the disease. (2) The degree of understanding of those around them and society has a huge effect on their way of life. (3) The inferiority of a woman who is not a "normal woman." (4) A "never-ending disease" in which problems continue even after the transition period. (5) Differences in the central point of the narrative depending on the age group. CONCLUSIONS: In this study, qualitative and inductive analyses of data from semistructured interviews with patients with PC revealed their experiences and thoughts. The results will provide a guide for young patients and the medical professionals who treat them. Accordingly, monitoring their lives until adulthood is necessary.

Congenital Risk Factors for Chronic Kidney Disease in Patients With Persistent Cloaca: Results From a Nationwide Survey in Japan.

BACKGROUND: We conducted a nationwide survey of persistent cloaca (PC) to investigate the renal function outcomes and factors affecting chronic kidney disease (CKD) in patients with PC. METHOD: Information from 466 patients with PC was obtained via a questionnaire in this study. The 290 patients (62.2%) with renal function data were classified into 2 groups based on their estimated glomerular filtration rate: advanced CKD group (<30 mL/min/1.73 m2 [or post-renal replacement therapy]) and non-advanced CKD group (≥30 mL/min/1.73 m2). Univariate and multivariate analyses were performed to identify risk factors for CKD that may affect the renal function, including renal and urinary tract malformations, associated anomalies, and urinary tract treatment. The advanced CKD group was divided into two groups based on age to evaluate age-related differences (younger- and older-age CKD groups). RESULTS: A regression analysis revealed that congenital renal malformations (odds ratio [OR]: 14.06, 95% confidence interval [CI]:3.07-131.65, p < 0.0001), urinary tract obstruction (OR:4.28, 95%CI:1.12-24.23, p < 0.05), and sacral agenesis (OR:4.54, 95% CI:0.84-30.67, p < 0.05) were significantly associated with advanced CKD. In the univariate analysis of factors affecting the renal prognosis, clean intermittent catheterization (CIC) (OR:4.18, 95%CI:1.21-16.45, p = 0.015), vesicostomy (OR:3.65, 95%CI:1.11-12.98, p = 0.019), and surgery for vesicoureteral reflux (OR:5.43, 95%CI:1.41-22.73, p = 0.006) were significantly associated with advanced CKD. Based on the univariate analysis, hydrometrocolpos was significantly more prevalent in the older-age CKD group compared to the younger-age CKD group (p < 0.05). CONCLUSION: CKD development in patients with PC is influenced by a complex interplay of factors, including renal malformations and neurogenic bladder dysfunction due to spinal anomalies. LEVEL OF EVIDENCE: III (Study of Diagnostic Test, Study of nonconsecutive patients, and/or without a universally applied "gold" standard).

Persistent Cloaca and Cloacal Variants in Males: Qualitative Review of a Neglected Anomaly.

Context: Cloacal malformations are rare and are typically reported in females. There are a few scattered reports in males. It is not clear why they are so rare in males since both sexes negotiate this stage of embryonal development. Aims: The present study aims to share our experience and review all the cases of persistent cloaca and cloacal variants in males reported in the literature. Materials and Methods: The male cloaca is defined as a single common channel of varying lengths with separate inlets for the urinary tract (urethra) anteriorly and the rectum posteriorly at its cranial end and with a solitary perineal orifice/opening for external drainage. We also carried out an electronic literature search for cloaca, persistent cloaca, common cloaca, cloacal dysgenesis, cloacal malformation, cloacal membrane agenesis, urorectal malformation sequence, rectourinary perineal fistula, sirenomelia, and caudal regression syndrome. Results: After eliminating other cloacal anomalies and persistent cloaca in females, we found a total of 22 males with persistent cloaca or cloacal variant reported in the literature. In addition, we are adding two cases we have managed since our previous report. Conclusions: An effort should be made to search for the presence of the common channel in male patients with a single perineal opening. Recognition of the anomaly, width of the common cloacal channel, location of the rectal pouch with relation to the sacrum or pubis, status of the spine and sacrum, and nature of the anal sphincter are vital pieces of information to successfully manage the anomaly. It would be worthwhile if future reports on the subject also include long-term information about urinary and fecal functions and continence.

A Systematic Review of Telehealth Utilization for Bowel Management Programs in Pediatric Colorectal Surgery.

Recent advancements in pediatric surgery have embraced telehealth (TH) modalities, transitioning from traditional in-person consultations to virtual care. This shift has broadened access to healthcare, potentially enhancing affordability, patient and caregiver satisfaction, and clinical outcomes. In pediatric colorectal surgery, telehealth has been effectively utilized to support Bowel Management Programs (BMPs) for children suffering from constipation and fecal incontinence. A systematic review was conducted to assess the effectiveness of virtual BMPs, analyzing studies from January 2010 to December 2023, sourced from MEDLINE (via PubMed), Embase, and the Cochrane Library, with five studies included. Remote BMPs, implemented through video or telephone consultations, reported satisfaction rates exceeding 75% among families, indicating a strong preference for virtual interactions over traditional visits. Significant findings from the studies include improvements in Vancouver and Baylor scores, reductions in the duration of multidisciplinary consultations, enhancements in pediatric quality of life and Cleveland scores, and decreased frequency of laxative treatments. The implementation of TH has facilitated patient-led care, enabling timely adjustments in treatment and efficient distribution of medical supplies. The findings suggest that virtual BMPs are a viable and effective alternative to conventional approaches, yielding high caregiver satisfaction and superior clinical outcomes while promoting patient independence.

The postoperative renal function of persistent cloaca patients treated by posterior sagittal anorecto-urethro-vaginopalsty: results of a nationwide survey in Japan.

PURPOSE: We investigated the postoperative renal function in persistent cloaca (PC) patients who underwent posterior sagittal anorecto-urethro-vaginopalsty (PSARUVP) and factors influencing the renal functional outcomes. METHODS: A questionnaire survey was distributed to 244 university and children's hospitals across Japan. Of the 169 patients underwent PSARUVP, 103 patients were enrolled in the present study. Exclusion criteria was patients without data of renal prognosis. RESULTS: The present study showed that renal anomalies (p = 0.09), vesicoureteral reflux (VUR) (p = 0.01), and hydrocolpos (p = 0.07) were potential factors influencing a decline in the renal function. Approximately half of the patients had a normal kidney function, but 45.6% had a reduced renal function (Stage ≥ 2 chronic kidney disease: CKD). The incidence of VUR was significantly higher in the renal function decline (RFD) group than those in the preservation (RFP) group (p = 0.01). Vesicostomy was significantly more frequent in the RFD group than in the RFP group (p = 0.04). Urinary tract infections (p < 0.01) and bladder dysfunction (p = 0.04) were significantly more common in patients with VUR than in patients without VUR. There was no association between the VUR status and the bowel function. CONCLUSIONS: Prompt assessment and treatment of VUR along with bladder management may minimize the decline in the renal function.

The Influence of Male Biostimulation on Cloacal Anatomy and Egg-Laying Behavior in Young Female Muscovy Ducks (Cairina moschata forma domestica).

The importance of Muscovy ducks in industrial poultry production is growing; however, little is known about the physiology of their reproductive cycles. This study investigated the influence of male biostimulation on female ducks before the commencement of the laying phase. A total of 30 muscovy ducks, hatched in the same year at 289-341 days of age, were divided into two groups of 15 birds each and kept with and without contact with a male duck until the day of first egg-laying-319 ± 14 and 335 ± 13, respectively. Before reaching egg-laying maturity, the cloacae of 29 adult ducks were subjected to daily clinical assessments. The evaluations yielded four unique categories of outcomes, determined by assessing factors such as the degree of redness and protrusion of the mucous membrane, the moisture level, and swelling of the cloacal sphincter muscle. The results of this study on biostimulation revealed that, on average, female ducks that had contact with males laid their first egg 16 days earlier, weighing 78.7 ± 3.0 g, compared to the isolated female ducks, weighing 79.1 ± 7.0 g. Furthermore, there was no significant difference observed in the mean initial egg weight between the groups (p = 0.841). The cloacal morphology indicated significant morphological changes 25-26 days before laying. Efforts to improve Muscovy production and develop biotechnological techniques to modify these ducks' reproductive cycle will benefit from these advancements.

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.

MR Imaging of the Fetal Genitourinary Tract.

Fetal MR imaging overcomes many of the technical barriers of ultrasound and is an important diagnostic tool for fetal genitourinary (GU) anomalies. It is suited for evaluation of GU anomalies because of the fluid-sensitive sequences and superior soft tissue contrast. Often GU malformations are part of a multisystem genetic or congenital condition, and imaging the entire fetus with MR adds additional clarity about the extent of disease. It adds confidence to diagnoses of renal agenesis, urinary tract dilation, cystic disease, and tumors. It is particularly useful to delineate anatomy in complex GU malformations. This additional information guides counseling.

Utilization of Indocyanine Green (ICG) Fluorescence in Patients with Pediatric Colorectal Diseases: The Current Applications and Reported Outcomes.

In pediatric colorectal surgery, achieving and visualizing adequate perfusion during complex reconstructive procedures are paramount to ensure postoperative success. However, intraoperative identification of proper perfusion remains a challeng. This review synthesizes findings from the literature spanning from January 2010 to March 2024, sourced from Medline/PubMed, EMBASE, and other databases, to evaluate the role of indocyanine green (ICG) fluorescence imaging in enhancing surgical outcomes. Specifically, it explores the use of ICG in surgeries related to Hirschsprung disease, anorectal malformations, cloacal reconstructions, vaginal agenesis, bladder augmentation, and the construction of antegrade continence channels. Preliminary evidence suggests that ICG fluorescence significantly aids in intraoperative decision-making by improving the visualization of vascular networks and assessing tissue perfusion. Despite the limited number of studies, initial findings indicate that ICG may offer advantages over traditional clinical assessments for intestinal perfusion. Its application has demonstrated a promising safety profile in pediatric patients, underscoring the need for larger, prospective studies to validate these observations, quantify benefits, and further assess its impact on clinical outcomes. The potential of ICG to enhance pediatric colorectal surgery by providing real-time, accurate perfusion data could significantly improve surgical precision and patient recovery.

Bladder Management and Continence in Girls With Cloacal Malformation After 3 Years of Age.

BACKGROUND: Multiple factors impact ability to achieve urinary continence in cloacal malformation including common channel (CC) and urethral length and presence of spinal cord abnormalities. Few publications describe continence rates and bladder management in this population. We evaluated our cohort of patients with cloacal malformation to describe the bladder management and continence outcomes. METHODS: We reviewed a prospectively collected database of patients with cloacal malformation managed at our institution. We included girls ≥3 years (y) of age and evaluated their bladder management methods and continence. Dryness was defined as <1 daytime accident per week. Incontinent diversions with both vesicostomy and enterovesicostomy were considered wet. RESULTS: A total of 152 patients were included. Overall, 93 (61.2%) are dry. Nearly half (47%) voided via urethra, 65% of whom were dry. Twenty patients (13.1%) had incontinent diversions. Over 40% of the cohort performed clean intermittent catheterization (CIC), approximately half via urethra and half via abdominal channel. Over 80% of those performing CIC were dry. In total, 12.5% (n = 19) required bladder augmentation (BA). CC length was not associated with dryness (p = 0.076), need for CIC (p = 0.253), or need for abdominal channel (p = 0.497). The presence of a spinal cord abnormality was associated with need for CIC (p = 0.0117) and normal spine associated with ability to void and be dry (p = 0.004) CONCLUSIONS: In girls ≥ 3 y of age with cloacal malformation, 61.2% are dry, 65% by voiding via urethra and 82% with CIC. 12.5% require BA. Further investigation is needed to determine anatomic findings associated with urinary outcomes. LEVEL OF EVIDENCE: IV.

OIES complex diagnosed by in utero ultrasound a case report.

INTRODUCTION AND IMPORTANCE: OEIS complex is a rare and complex anomaly of the genitourinary and intestinal tract. It includes Omphalocele, Exstrophy of cloaca, Imperforate anus and Spinal defects. PRESENTATION OF CASE: We are reporting a case of OEIS complex. CLINICAL DISCUSSION: Cloacal exstrophy is considered the most severe ventral abdominal wall defect. Diagnosis is primarily antenatal based on the presenting features on ultrasonography. Management requires initial resuscitation and stabilization followed by either single staged closure or multistage procedures by multi-disciplinary surgical team. CONCLUSION: The introduction of better diagnostic techniques and the detection of fetal malformations during pregnancy is it's the cornerstone of care.

Discrepancies Between Imaging Reports and Operative Findings in Patients With Cloaca: A Call for Expansion of the Mullerian Anomalies Classification.

BACKGROUND: There is wide variation in the language used to describe Mullerian structures. To standardize terminology, the American Society of Reproductive Medicine (ASRM) created the Mullerian Anomalies Classification (MAC) in 2021. The objective of this study was to evaluate the applicability of the MAC nomenclature to pediatric patients with cloaca. METHODS: A retrospective review of all patients with cloaca was performed at a single institution. Descriptions of Mullerian structures were evaluated and compared to the ASRM MAC categories. Descriptive statistics were used to report findings. RESULTS: 36 patients with cloaca were identified, 13 (36%) of whom had congenital Mullerian structures that could not be adequately described by the MAC terminology. All 13 patients had two hemiuteri that were not connected in the midline and were not accurately described as uterus didelphys. Additionally, 5 of these 13 patients had reproductive anatomy that was connected by a fistula or ectopic connection to other pelvic structures. CONCLUSION: Despite the ASRM expansion of the Mullerian anomalies nomenclature, more than a third of our patients with cloaca could not have their Mullerian structures accurately described. Describing anatomy with accurate and consistent language can improve communication between healthcare providers and may allow patients and families to better anticipate fertility options.

Novel autopsy and genetic findings in an acardiac twin: case report and literature review.

Twin reversed arterial perfusion (TRAP) sequence is a rare complication of monochorionic twinning whereby a donor twin perfuses an acardiac twin via aberrant vascular anastomoses. The resulting paradoxical retrograde blood flow supplying the acardiac twin is oxygen-poor, leading to some of the most severe malformations encountered in humans. Though the first descriptions of acardiac twins date back to at least the 16th century, the pathophysiologic processes which underpin the development of TRAP sequence are still being elucidated. Theories on the pathogenesis of TRAP sequence include deficiencies intrinsic to the embryo and primary abnormalities of the placental vasculature. Autopsy studies continue to provide clues to the underlying pathogenesis of TRAP sequence, and the characterization of the spectrum of manifestations that can be observed in acardiac twins. Herein, we present the clinical, autopsy, and molecular findings in a unique case of TRAP sequence. Novel findings include a primitive cloaca-like structure and chromosomal aberrations involving 6q11.1 and 15q25.1.

Genome sequencing of drake semen micobiome with correlation with their compositions, sources and potential mechanisms affecting semen quality.

Artificial insemination (AI) technology has greatly promoted the development of the chicken industry. Recently, AI technology has also begun to be used in the duck industry, but there are some problems. Numerous researchers have shown that microbes colonizing in semen can degrade semen quality, and AI can increase the harmful microbial load in hen's reproductive tract. Different from the degraded external genitalia of roosters, drakes have well-developed external genitalia, which may cause drake semen to be more susceptible to microbial contamination. However, information on the compositions, sources, and effects of semen microbes on semen quality remains unknown in drakes. In the current study, high-throughput sequencing technology was used to detect microbial communities in drake semen, environmental swabs, cloacal swabs, and the spermaduct after quantifying the semen quality of drakes to investigate the effects of microbes in the environment, cloaca, and spermaduct on semen microbiota and the relationships between semen microbes and semen quality. Taxonomic analysis showed that the microbes in the semen, environment, cloaca, and spermaduct samples were all classified into 4 phyla and 25 genera. Firmicutes and Proteobacteria were the dominant phyla. Phyllobacterium only existed in the environment, while Marinococcus did not exist in the cloaca. Of the 24 genera present in semen: Brachybacterium, Brochothrix, Chryseobacterium, Kocuria, Marinococcus, Micrococcus, Rothia, Salinicoccus, and Staphylococcus originated from the environment; Achromobacter, Aerococcus, Corynebacterium, Desemzia, Enterococcus, Jeotgalicoccus, Pseudomonas, Psychrobacter, and Turicibacter originated from the cloaca; and Agrobacterium, Carnobacterium, Chelativorans, Devosia, Halomonas, and Oceanicaulis originated from the spermaduct. In addition, K-means clustering analysis showed that semen samples could be divided into 2 clusters based on microbial compositions, and compared with cluster 1, the counts of Chelativorans (P < 0.05), Devosia (P < 0.01), Halomonas (P < 0.05), and Oceanicaulis (P < 0.05) were higher in cluster 2, while the sperm viability (P < 0.05), total sperm number (P < 0.01), and semen quality factor (SQF) (P < 0.01) were lower in cluster 2. Furthermore, functional prediction analysis of microbes showed that the activities of starch and sucrose metabolism, phosphotransferase system, ABC transporters, microbial metabolism in diverse environments, and quorum sensing pathways between cluster 1 and cluster 2 were significantly different (P < 0.05). Overall, environmental/cloacal microbes resulted in semen contamination, and microbes from the Chelativorans, Devosia, Halomonas, and Oceanicaulis genera may have negative effects on semen quality in drakes by affecting the activities of starch and sucrose metabolism, phosphotransferase system, ABC transporters, and quorum sensing pathways that are associated with carbohydrate metabolism. These data will provide a basis for developing strategies to prevent microbial contamination of drake semen.

T2-based magnetic resonance genitography in children with complex anorectal malformations: experience at a tertiary pediatric hospital in Latin America.

In children with anorectal malformations (ARMs), it is essential to have a diagnostic imaging method that helps with the evaluation of the internal anatomy. In patients with a persistent cloaca, an ARM variant, in which the measurement of the urethral channel and common channel determines surgical management, there are multiple options for imaging. Magnetic resonance imaging (MRI) is an excellent method for this purpose, from which accurate measurements of channel length can be obtained. Additionally, the use of volumetric/isotropic sequences allows multiplanar reformatting. We present our experience with pelvic MRI and intracavitary non-paramagnetic contrast (MR genitography). This method uses volumetric T2-weighted images and the instillation of saline solution as a contrast agent to distinguish the common channel, length of the urethra, anatomy of the vagina, and presence and location of the rectal fistula. We believe this technique to be particularly useful for those working in settings with limited MRI resources.

Endoscopy and rectal enema for fecal collection in wild sea turtles (Chelonia mydas, Eretmochelys imbricata) in a field setting.

Forty-seven free-ranging sea turtles (46- Chelonia mydas, 1- Eretmochelys imbricata) were examined via novel use of an endoscopy combined with a rectal enema to obtain large fecal sample volumes. The cloaca was insufflated using an endoscope, after which the bladder and rectum separated, allowing access to the colon. Environmental conditions and location influenced the performance of the procedure initially, but after several attempts the procedure was successfully initiated. In all cases, fecal samples were obtained, and the animals were released to their respective locations. Fecal sample collection using this approach enhances the ability to obtain diagnostic information and perform other scientific analyses of sea turtles.

How we select our surgical approach for cloacal reconstruction.

During cloacal reconstruction, we consider both common channel (CC) and urethral length when deciding between total urogenital mobilization (TUM) and a urogenital separation (UGS). Our concern about TUM in the case of a short urethra is resultant bladder neck incompetence, while conversion to UGS after completing the TUM dissection may result in urethral injury. Use of an interposition flap harvested from the ischiorectal fossa is another measure we use to prevent potential complications.

Sex identification in Australian skinks (Egernia stokesii, E. hosmeri, E. striolata) using cloacoscopy.

Thirteen adult healthy captive skinks, six Gidgee spiny-tailed skinks (Egernia stokesii), three Hosmer's spiny-tailed skinks (Egernia hosmeri) and four tree crevice-skinks (Egernia striolata), were submitted to the study. The weight of the animals ranged from 28 g to 146 g. All skinks were explored during their putative mating season, which is December. Lizards were restrained manually and positioned in ventral recumbence. Cloacoscopy was performed with the rigid endoscope, protecting channel, endocamera and recording system Telepack-Pal (Karl Storz Endoskope, Tuttlingen, Germany). While the endoscope was gently introduced into the cloaca and advanced into the coprodeum sterile saline was flushed into the cloaca through the protecting channel. The endoscope was then slowly withdrawn to allow visualization of the main structures of the urodeum and proctodeum. Male skinks are characterized by the presence of urethral papillae and only one horizontal septum which divides the chamber of the urodeum into two subchambers. Female skinks are characterised by the presence of two septa. The central-dorsal fold that divides the urodeum into two pouches in female skinks is absent in males. Cloacoscopy proved an effective method of sex identification and can be considered a valuable method for breeding and conservation in monomorphic skink lizards.
