RESUMO
Although 40 years have passed since the first case of DiGeorge's syndrome was described, and the knowledge about this disorder has steadily increased since that time, 22q11.2 deletion syndrome (DS) remains a challenging diagnosis because its clinical presentation varies widely. We describe an infant with 22q11.2 DS who presented with annular pancreas, anorectal malformation, Morgagni-type congenital diaphragmatic hernia, and ventricular septal defect. This constellation of anomalies has never been described in DiGeorge's syndrome. Here, we provide a case presentation and a thorough review of the literature.
RESUMO
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.
RESUMO
Background and Objective: Although more frequent in the adult population, rectal prolapse is a common anorectal condition that can occur in children and adolescents. While many cases spontaneously resolve without the need for intervention, the advent of newer minimally invasive procedures and operations have provided options for pediatric patients. Here, we review the pathophysiology, etiology, presentation, diagnosis and principles of management of rectal prolapse in the pediatric population as it has evolved over the past several decades. Methods: The literature was queried from free databases available to the public including the National Institute of Health National Library of Medicine MEDLINE and PubMed for manuscripts published from January 1, 1975 to December 1, 2023. Manuscripts without an accompanying English translation or those written entirely in foreign languages were excluded. Key Content and Findings: Numerous conditions contribute to rectal prolapse in children, including constipation, gastrointestinal infectious and non-infectious etiologies, cystic fibrosis, malnutrition, neurogenic, anatomic, lead points, and abuse. Initial management of rectal prolapse is medical management, addressing the underlying condition associated with rectal prolapse along with attempted manual reduction. For patients with recurrent rectal prolapse, a variety of noninvasive and procedural management options are available including injection sclerotherapy and anal encirclement in addition to surgical rectopexy by open and newer minimally invasive methods. Conclusions: Despite significant advances in the evaluation, procedural and surgical management of pediatric anorectal conditions in the last few decades, there continues to be substantial variation in clinicians' and surgeons' practice for the treatment of rectal prolapse in children and adolescents. Much remains to be studied in the future to improve clinical outcomes for this patient population.
RESUMO
PURPOSE: Early post-operative fever (< 48 h) is common in adults and children and seldom indicative of an infection. Guidance to limit excessive evaluation in adults is well-characterized but similar studies for the pediatric population is scarce. This study was performed to better clarify which infants should undergo investigation for post-operative fever after colorectal reconstructive surgical procedures. METHODS: We performed a retrospective chart review of all infants under one year of age who underwent elective reconstruction for anorectal malformations (ARM) and Hirschsprung Disease (HD) between June 2018 and April 2020 at a single institution. Patient and perioperative characteristics were analyzed to evaluate for possible factors associated with infection. RESULTS: Sixty-eight infants met study criteria - 38 (55.9%) had HD and 30 (44.1%) had ARM. Twenty-two infants (32.4%) had early post-operative fever. A definitive infectious cause was identified in only two infants. The presence of a colostomy pre-operatively and longer operative times were associated with increased risk of post-operative fever (62.5% vs. 22.7% and 175 min vs. 150 min respectively, p < 0.05). CONCLUSION: Early post-operative fever in infants after colorectal surgery is common and rarely associated with an infection. Further research is needed to determine which infants require further work-up and which can be safely observed.

INTRODUCTION AND HYPOTHESIS: Standardized digital rectal examination (DRE) correlates with anorectal manometry (ARM) measures. However, less is known about the relationship between DRE/ARM measures and patient-reported outcomes (PROs), especially among women with fecal incontinence (FI). Our aims were to evaluate associations between DRE and ARM measures and compare PROs with diagnostic evaluation measures for women with FI. METHODS: We analyzed data from the parent clinical trial, Controlling Anal incontinence by Performing Anal exercises with Biofeedback or Loperamide (CAPABLe). We pooled data from randomized women who completed standardized ARM, DRE, and validated PROs at baseline and 12 and 24 weeks post-treatment initiation. PROs included FI severity, impact on quality of life, and bowel diary data. We analyzed ARM pressure and volume data and DRE using the Digital Rectal Examination Scoring System (DRESS) resting and squeeze mean scores. We used Spearman Rank Correlation to measure associations between the ARM measures and mean DRESS scores, and between PROs and ARM/DRESS scores. RESULTS: Among 291 randomized women with ARM and DRE data, the correlation between DRESS and ARM resting measures was 0.196 (p<0.001) and between squeeze measures was 0.247 (p<0.001). At most timepoints, PROs more consistently correlated with squeeze ARM pressures and squeeze DRESS scores than resting measures. CONCLUSIONS: We found weak correlations between ARM and DRE measures and between those measures and PROs. Although DRE and ARM are commonly used diagnostic measures among women with FI, the weak correlations with patient-reported symptoms raises questions about their utility in clinical care.
RESUMO
It has not yet been proven whether sepsis affects the tissue around the anal canal. To address this issue, we established three-dimensional models for various types of anorectal abscesses and utilize 3D reconstruction of Magnetic Resonance Imaging scans to assess the extent of muscle damage caused by anorectal abscesses. Patients diagnosed with anorectal abscess, selected from January 2019 to January 2022 underwent pre- and post-operative scanning of pelvic floor and perianal tissues. The aforementioned structures were segmented for the reconstruction of a three-dimensional visual model and measurement of volumes for the abscess as well as the internal and external sphincters and levator ani muscle. The study included a total of 42 patients. Three-dimensional visualization models were created for different types of anorectal abscesses, including perianal, intersphincteric, ischiorectal, and supralevator abscesses. No statistically significant differences were observed in the volume of the internal sphincter, external sphincter, and levator ani muscle between pre- and post-operative patients. The 3D model of anorectal abscess, reconstructed from MRI data, offers a precise and direct visualization of the anatomical structures associated with various types of anorectal abscesses. The infection did not result in any damage to the internal and external anal sphincter and levator ani muscle.

Background: The present study attempted to evaluate the effect of oral gabapentin and acetaminophen for postoperative analgesia in anorectal surgery. Methods: This double-blind clinical trial was carried out on 144 patients who were candidates for anorectal surgery. The patients were randomly assigned into three groups of control, acetaminophen 500 mg, and gabapentin 300 mg for two hours before the surgery. Data on pain severity based on the visual analog scale (VAS) were evaluated and analyzed. Results: The results of the current study indicated that in patients taking acetaminophen and gabapentin tablets before surgery, the amount of postoperative pain decreased, and the amount of decrease in postoperative pain in the patients who received acetaminophen and gabapentin tablets compared with the placebo group was significant (P<0.001). Also, an evaluation was done using a proposed fuzzy logic model. Conclusion: Taking acetaminophen and gabapentin tablets one hour before the operation causes a significant reduction in postoperative pain in patients who are candidates for anorectal surgery. The results are promising and encourage one to pay attention to more studies with the goal of possibly using them as a decision-support model in the future.
RESUMO
Parenting starts much before the baby is born. It always comes with mixed feelings during parenting. Therefore, it is of interest to report the quality of life and caregiver burden for Indian children with post-operative congenital anorectal malformations. We recruited total 56 caregivers for the present study. Data shows that the highest caregiver burden in economical and the lowest in psychological. Quality of life (QOL) was highest in physical domain and there was moderate negative correlation among caregiver burden, psychological health, and social relationship.
RESUMO
BACKGROUND: Postoperative urinary retention (POUR) is a common complication of anorectal surgery. This study was to determine the incidence of POUR in anorectal surgery for benign anorectal diseases, identify its risk factors, and establish a nomogram for prediction of POUR. METHODS: A nested case-control study was conducted. The clinical data of patients were collected, and the incidence of POUR was analyzed. Univariate analysis was used to identify the risk factors associated with POUR, and multivariate logistic regression analysis was used to determine independent risk factors for POUR. A nomogram for the preoperative prediction of POUR using a logistic regression model was developed (n = 609). RESULTS: The incidence of POUR after anorectal surgery for benign anorectal diseases was 19.05%. The independent risk factors for POUR were: female (P = 0.007); male with benign prostatic hyperplasia (BPH) (P = 0.001); postoperative visual analogue scale (VAS) score > 6 (P = 0.002); patient-controlled epidural analgesia (PCEA) (P = 0.016); and a surgery time > 30 min (P = 0.039). In the nomogram, BPH is the most important factor affecting the occurrence of POUR, followed by a postoperative VAS score > 6, PCEA, surgery time > 30 min, and sex has the least influence. CONCLUSION: For patients undergoing anorectal surgery for benign anorectal diseases, preventive measures can be taken to reduce the risk of POUR, taking into account the following risk factors: female or male with BPH, severe postoperative pain, PCEA, and surgery time > 30 min. Furthermore, we developed and validated an easy-to-use nomogram for preoperative prediction of POUR in anorectal surgery for benign anorectal diseases. TRIAL REGISTRATION: China Clinical Trial Registry: ChiCTR2000039684, 05/11/2020.

BACKGROUND: Spastic pelvic floor syndrome (SPFS) is a refractory pelvic floor disease characterized by abnormal (uncoordinated) contractions of the external anal sphincter and puborectalis muscle during defecation, resulting in rectal emptation and obstructive constipation. The clinical manifestations of SPFS are mainly characterized by difficult defecation, often accompanied by a sense of anal blockage and drooping. Manual defecation is usually needed during defecation. From physical examination, it is commonly observed that the patient's anal muscle tension is high, and it is difficult or even impossible to enter with his fingers. AIM: To investigate the characteristics of anorectal pressure and botulinum toxin A injection combined with biofeedback in treating pelvic floor muscle spasm syndrome. METHODS: Retrospective analysis of 50 patients diagnosed with pelvic floor spasm syndrome. All patients underwent pelvic floor surface electromyography assessment, anorectal dynamics examination, botulinum toxin type A injection 100 U intramuscular injection, and two cycles of biofeedback therapy. RESULTS: After the botulinum toxin A injection combined with two cycles of biofeedback therapy, the patient's postoperative resting and systolic blood pressure were significantly lower than before surgery (P < 0.05). Moreover, the electromyography index of the patients in the resting stage and post-resting stages was significantly lower than before surgery (P < 0.05). CONCLUSION: Botulinum toxin A injection combined with biofeedback can significantly reduce pelvic floor muscle tension in treating pelvic floor muscle spasm syndrome. Anorectal manometry is an effective method to evaluate the efficacy of treatment objectively. However, randomized controlled trials are needed.
RESUMO
Congenital pouch colon (CPC) is a rare congenital abnormality, in which a pouch-like dilatation partially or completely replaces the colon, creating a fistula with the urogenital. Congenital colonic pouch is an extremely rare congenital disease mainly reported in India, and to date there are no reported cases in Lebanon. In this paper, we present a case of full-term male neonate diagnosed with a congenital colon pouch in Lebanon. A full-term neonate presented with imperforate anus, abdominal distention, and vomiting. Diagnostic assessments revealed a well-encapsulated mass compressing the intestines and ureter. Surgical intervention identified a type I CPC with a meconium-filled pouch directly connected to the small intestine, and an absent ileocecal valve, prompting an ileostomy. Following the surgery, no postoperative complications were noted. Early imaging can help address the diagnosis to start the appropriate management, plan for surgery to prevent the development of a megacolon and therefore, perforation. The objective is to be aware and consider congenital colonic pouch diagnosis after encountering newborns with such clinical presentation in order to direct clinical investigations toward the diagnosis and treatment of the case early, thus reducing the risk of complications and improving the patient's quality of life.
RESUMO
OBJECTIVE: Endoscopic submucosal dissection (ESD) is a specific procedure that uses an electrosurgical knife for en-bloc resectioning large tumors. However, no study has examined the effect of ESD on the defecation function of patients with rectal tumors. We aimed to investigate the potential effects caused by ESD by analyzing changes in the morphology and movement of the anorectum pre- and post-ESD. METHODS: This prospective observational study included 11 patients with anorectal tumors who underwent ESD between April 2020 and February 2022. Pre-ESD assessments included anorectal manometry and defecography. Post-ESD assessments were conducted 2 months later, including anorectal manometry, defecography, and proctoscopy for ulcer and stenosis evaluation. RESULTS: The median patient age was 73 years, including seven males and four females. Eight patients (73%) had a tumor in the lower rectum, and the extent of resection was less than 50% of the rectal lumen. Resection reached the dentate line in six cases (55%). In the patients with post-ESD mucosal defects involving the dentate line, the median of functional anal canal length significantly decreased from (3.4 cm pre-ESD to 2.8 cm post-ESD, p = 0.04). Defecography revealed one case with incomplete evacuation (<50%) and incontinence post-ESD. Interestingly, patients with pre-existing rectoceles noted resolution of lesions post-ESD. None of the patients reported daily constipation or fecal incontinence. CONCLUSIONS: While rectal ESD is unlikely to cause significant real-world defecation difficulties, alterations in rectal and anal canal morphology and function may occur if the dentate line is involved in the resection range.
RESUMO
PURPOSE: Surgical procedures for anorectoplasty for anorectal malformations (ARMs), particularly rectourethral fistula (RUF), depend on the institution. We investigated the diagnosis and treatment of RUF in male patients with ARMs in Japan using a questionnaire survey. METHODS: An online survey inquiring about the diagnosis and treatment (diagnostic modalities, surgical approaches, fistula dissection devices, and fistula closure techniques) of each type of ARM in male patients was conducted among institutional members of the Japanese Study Group of Anorectal Anomalies. Fisher's exact test was used to compare surgical methods between posterior sagittal anorectoplasty (PSARP) and laparoscopy-assisted anorectoplasty (LAARP). RESULTS: Sixty-one institutions (100%) completed the survey. LAARP was the preferred approach for high-type ARM (75.4%). PSARP was preferred for intermediate-type ARM (59.0%). Monopolar devices were most commonly used (72.1%) for RUF dissection. Blunt dissection was more frequent in the PSARP group (PSARP vs. LAARP: 55.6 vs. 20.0%, p < 0.005). Cystoscopy/urethroscopy to confirm the extent of dissection was used more frequently in the LAARP group (70.0% vs. 25.0%, p < 0.005). Clips and staplers were used more frequently in the LAARP group (p < 0.05). CONCLUSION: Distinct fistula management strategies for PSARP and LAARP were revealed. Further studies are needed to investigate the postoperative outcomes associated with these practices.

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.
RESUMO
Introduction: Reconstruction of a cloacal defect in a girl is often difficult and complicated.[1] This is most often done either by the sacro-perineal route or through the posterior sagittal route.[2] The procedures may involve total mobilization of the cloaca with or without the creation of a lower vagina with the help of a loop of vascularized bowel.[3] In our approach, such defects can be corrected using the lower anorectum for the creation of a lower vagina and abdominoperineal pull-through of the proximal divided bowel. This method can be used both in short and long common channel cloaca. Materials and Methods: We have used this procedure in one patient of posterior cloaca and four patients of anterior cloaca. These operations were done in patients of 1 year and 6 months to 4 years. Only one patient is waiting for the closure of the colostomy. Results: In all the cases, the urethra, the vagina, and the anus were successfully separated. Conclusion: This operation restores normal pelvic anatomy and physiology with minimal mutilation of the pelvic floor.
RESUMO
This is a case series of three patients who presented with complex anorectal fistulas. Each patient underwent repair of complex anorectal fistulas with biologic mesh. We will discuss each case and our institution's experience with this relatively new technique. This case series demonstrates the use of biologic mesh for the repair of complex anorectal fistulas. Three patients are discussed who underwent repair of perianal fistulas using ACell mesh by two separate surgeons. We will discuss the rationale for offering this treatment, as well as the advantages and disadvantages. The use of biologic mesh in perianal fistulas is a relatively new topic that needs further investigation. Perianal fistulas can be difficult to manage for both patients and surgeons. There are many options for repair, ranging from simple to complex. Biologic mesh for complex fistulas may be a useful option to avoid the morbidity of more complex repairs, such as flaps.
RESUMO
INTRODUCTION: Anorectal malformations (ARMs) may be associated with congenital anomalies affecting other body parts namely vertebral, anorectal, cardiac, tracheoesophageal, renal, and limb (VACTERL) with varying incidences of 7%-60% . Genitourinary defects might occur approximately in 50% of all patients with anorectal malformations hence patients should be evaluated from birth to rule out these defects. OBJECTIVE: To identify urological anomalies associated with anorectal malformation in southwestern Uganda. STUDY DESIGN: This was a descriptive retrospective cohort study conducted at our regional referral hospital in Southwestern Uganda involving patients who have undergone surgical correction of ARMs between June 2021 and July 2023. RESULTS: The overall prevalence of renal anomalies in our study patient population was 18.05%. Of those with ARM-associated renal anomalies, Specific anomalies included; renal agenesis (6.8%), hydronephrosis, (4.5%), duplex collecting system (3.8%), crossed fused kidney (1.5%), and ectopic kidney (0.75%). (Table) DISCUSSION: We found that the prevalence of ARM-associated renal anomalies was 18.05%, and the commonest anomaly was unilateral agenesis (6.8%) similar to other studies. Previous data have shown renal anomalies are common anomalies in ARM. While the exact values vary across studies, they all concluded that the rate of associated anomalies is extremely high in ARMs and warrants a thorough preoperative investigation once the ARMs are detected. This finding therefore underscores the importance of thorough evaluation and a multidisciplinary approach of care and follow-up system for ARM management including urologists even when the children are asymptomatic now. The main limitation of our study was missing information on patients' charts, we were not able to get the diagnosis since most patients didn't have their discharge forms at the time of evaluation. CONCLUSION: ARM associated with renal anomalies may remain undiagnosed and asymptomatic. Those identified as asymptomatic need to be followed in a multidisciplinary fashion including pediatric urologists.
RESUMO
OBJECTIVES: To use three-dimensional anorectal ultrasonography (3D-US) to evaluate the outcome of ligation of the intersphincteric fistula tract (LIFT) in patients with crypto-glandular transsphincteric fistula and describing the patterns of healing, failure, and recurrence rate. METHODS: After classifying the fistula and determining the length of the sphincter muscle to be transected, the patients were submitted to LIFT. The accuracy of pre- and postoperative 3D-US with 360° endoprobe (16 MHz) with automatic scanning and clinical findings was evaluated against surgical findings. Three outcomes were considered: healing, failure (persistent anal fistula through the original external opening or intersphincteric), and recurrence (reappearance of the anal fistula). RESULTS: Sixty-three patients of both sexes were evaluated. The 3D-US assessment revealed primary healing in 50 (79.3%) patients, although in 6 (9.5%) cases healing was delayed and the cavity was without communication with the anal canal. The procedure failed in 9 (15.9%) and fistula recurred in 4 (6.3%), all of whom underwent a second surgery based on a new 3D-US, resulting in a 92.3% (12/13) healing rate on 3D-US. CONCLUSIONS: A 3D-US was found to be useful in the preoperative assessment of fistulas by quantifying the percentage of muscle to be transected, and in the postoperative assessment by identifying healing, types of failure, and recurrence. The 3D-US was accurate and consistent with surgical findings.
RESUMO
Background: Observational studies have indicated that obesity is a risk factor for anorectal abscess (ARB). However, it remains unclear whether a causal genetic relationship exists between obesity and ARB. Methods: Univariate and multivariate Mendelian randomization (MR) were conducted using data from a large, published genome-wide association study (GWAS) of European ancestry to infer a causal relationship between obesity and ARB. Inverse variance weighted (IVW) analysis served as the primary analysis method, with results reported as odds ratios (OR). Results: MR analysis revealed that body mass index (BMI) positively affects ARB (OR 1.974, 95% confidence interval (CI) 1.548-2.519, p = 4.34 × 10-8). The weighted median method (OR = 1.879, 95% CI 1.248-2.829, p = 0.002) and Bayesian model averaging (BMA) (OR = 1.88, 95% CI 1.477-2.392, p = 2.85 × 10-7) also demonstrated consistent results. Subsequently, the impact of several obesity-related characteristics on ARB was assessed. Body fat percentage (BF), whole body fat mass (FM), waist circumference (WC), and hip circumference (HC) were found to be causally associated with an increased risk of ARB. However, these associations vanished after adjusting for BMI effects. Conclusion: The study confirms a positive causal effect of obesity on ARB, highlighting that reasonable weight control is an important strategy to reduce the incidence of ARB.
RESUMO
Background and aims: Crohn's disease (CD)-associated intestinal cancers are characterized by their high incidence, particularly at the anorectal site in the Japanese population. Accumulating evidence revealed that younger-onset sporadic colorectal cancer may exhibit unique biological features. To the best of our knowledge, few previous articles reported clinicopathological features in patients with CD-associated anorectal cancer (CDAAC). Therefore, we aimed to clarify the relationship between the younger onset of cancer and clinicopathological characteristics and prognosis, and the efficacy of cancer surveillance in patients with CDAAC. Methods: CD patients who had been diagnosed with intestinal cancers from 1983 to 2020 were collected from 39 Japanese institutions in this study. Of 316 patients with CD-associated intestinal cancers, we analyzed 211 patients with CDAAC. We divided the patients into two groups according to the median age at cancer diagnosis (45 years old). Results: Younger-onset CDAAC (YO-CDAAC) patients were significantly more likely to have a poor outcome than those with older-onset CDAAC (OO-CDAAC) in terms of both disease-free survival (DFS) (p = 0.0014) and overall survival (OS) (p = 0.023). Multivariate analysis showed that age under 45 years old at diagnosis of cancer was one of the independent factors for poor DFS and OS (hazard ratios: 2.15, 95% confidence interval: 1.09-4.26, p = 0.028, hazard ratios: 1.95, 95% confidence interval: 1.05-3.60, p = 0.033, respectively). Patients detected via surveillance showed significantly better DFS and OS rates than symptomatic patients in YO-CDAAC (p = 0.012 and 0.0031, respectively). Conclusions: YO-CDAAC may have a poorer prognosis compared with OO-CDAAC. Surveillance could be important to improve cancer prognosis, especially in young CD patients with anorectal disease.
