RESUMO

BACKGROUND: Long-term urinary outcomes after anorectal malformation (ARM) repair are affected by surgical approach and sacral anomalies. This study aimed to compare laparoscopic-assisted anorectoplasty (LAARP) and posterior sagittal anorectoplasty (PSARP) in terms of urinary complications. METHODS: Between 2001 and 2022, 45 patients were treated with LAARP or PSARP. The rectourethral fistula and inflow angle between the fistula and rectum was confirmed by preoperative colonography. The incidence of urinary complications and treatment were compared between the two groups. RESULTS: Four patients (14%) had remnant fistula and five patients (17%) had neurogenic bladder dysfunction in LAARP group, while three patients (18%) had urethral injury in PSARP group. All patients with remnant fistula were asymptomatic and followed without treatment. The incidence of remnant fistula improved between earlier decade and later decade. In all cases with urethral injury, suture repair was performed and no postoperative leakage was noted. All five patients with neurogenic bladder dysfunction had spine abnormalities that required clean intermittent catheterization (CIC) and two were free from CIC finally. CONCLUSIONS: It is important to check inflow angle preoperatively to prevent remnant fistula. For PSARP, meticulous dissection is required when separating fistula from urethra because they create common wall. The most contributing factor to neurogenic bladder is sacral anomalies. Preoperative evaluation and postoperative urinary drainage are important.

RESUMO

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.

RESUMO

OBJECTIVE: To present a unique series of children with previously repaired anorectal malformations (ARM) with subsequent urethral pathology repaired via a posterior sagittal exposure and highlight the associated technical advantages. METHODS: Using a retrospective review of all procedures performed in our pediatric colorectal and pelvic reconstruction program from January 2020 through December 2022, we compiled a case series of patients with a history of ARM and prior posterior sagittal anorectoplasty (PSARP) who had urethral pathology and concurrent indication for redo-PSARP. Clinical features, operative details, and postoperative outcomes were collected. RESULTS: Six male patients presented at a median age of 4.3 years, all born with an ARM of recto-urinary fistula type, of which 3 were recto-prostatic, 1 recto-bladder-neck, and 2 unknown type. In addition to redo-PSARP, 2 underwent remnant of the original fistula excision and 4 had urethral stricture repair. One required post-operative Heineke-Mikulicz anoplasty. Patients underwent cystoscopy 4-6 weeks post-reconstruction, and none showed urethral stricture requiring treatment. Post-procedurally, 5 patients were able to void urethrally and 1 required additional bladder augmentation/Mitrofanoff. CONCLUSION: Redo-PSARP completely mobilizes the rectum, thereby providing excellent exposure to the posterior urethra for repair. This approach also allows the option of a rectal flap for augmented urethroplasty as well as harvest of an ischiorectal fat pad for interposition.

RESUMO

BACKGROUND: In recent decades, magnetic resonance imaging (MRI) has gained prominence as a standard diagnostic method for preoperative assessment in patients with anorectal malformations and a colostomy, with the potential to replace the classic fluoroscopic distal pressure colostogram (FDPC). Three MRI techniques are available: MRI-distal pressure colostogram with gadolinium (MRI-DPCG) or saline (MRI-DPCS) instillation into the colostomy and native MRI without colostomy instillation. OBJECTIVE: To evaluate and compare the diagnostic accuracy of MRI (native MRI, MRI-DPCG and MRI-DPCS) in the preoperative workup of boys with an anorectal malformation and a colostomy and to compare it to FDPC. MATERIALS AND METHODS: Sixty-two boys with preoperative MRI using one of the three approaches and 43 with FDPC met the inclusion criteria for this retrospective study. The presence and localization of rectal fistulas according to the Krickenbeck classification were evaluated and compared with intraoperative findings. RESULTS: The accuracy of fistula detection for MRI in general (regardless of the technique), MRI-DPCS, MRI-DPCG, native MRI and FDPC was 95% (59/62, P<0.001), 100% (12/12, P=0.03), 100% (30/30, P<0.001), 85% (17/20, P=0.41) and 72% (31/43, P=0.82), respectively. The accuracy of describing fistula type in patients with a correctly detected fistula using these methods was 96% (45/47, P<0.001), 100% (9/9, P<0.001), 100% (23/23, P<0.001), 87% (13/15, P<0.001) and 67% (13/21, P=0.002), respectively. CONCLUSION: MRI is a reliable method for detecting and classifying fistulas in boys with an anorectal malformation and a colostomy and can be considered the modality of first choice for preoperative workup.

RESUMO

AIM: Compare the laparoscopic treatment (LT) and the posterior sagittal anorectoplasty treatment (ST) of the rectovaginal fistulas (RvaF) in a single center. We have previously reported feasibility and results of LT in this rare variety of anorectal malformations (ARM) [1-3]. MATERIAL AND METHODS: 19 patients were treated between February 2000 and November 2020. Nine underwent a LT and 10 a ST. Both surgical techniques were previously described. [2][4][5] The distal posterior wall of the vagina was kept intact in the LT. A technical change was introduced in the ST for that purpose. The fistula was treated from the inside of the rectum, avoiding the opening of the distal vagina as described for the treatment of a urethra rectal bulbar fistula in males. Age at operation, associated anomalies, sacral ratio index (SR), complications, urinary continence, presence of spontaneous intestinal movements, constipation, soiling and requirements of bowel management program (BMP) were analyzed. RESULTS: Associated anomalies occurred in 17 patients (89.5 %), 63 % of which were urological. Five (26 %) had a SR below 0.4; 4 in the LT group and 1 in the ST group. The mean age at the time of operation was 23.2 (8-59) in ST and 17.6 months (4-32) in LT. Average operative time was 190.4 min for ST (120-334) and 195.8 min (90-270) for LT (p 0.13). One patient in the LT group presented a mild rectal prolapse and 2 a partial wound dehiscence after the ST. Only 15 patients were evaluable for functional results (8 in ST and 7 in LT). Mean follow up was 83 months (12-197). All patients are clean with a bowel management program. Five of the 7 patients undergoing a LT had a bad prognosis (SR < 0,4). Three (43 %) are clean with diet or any treatment, 3 (43 %) using laxatives or enemas and 1 (14 %) with a trans anal irrigation system. Only 1 of the 8 patients in the STgroup had a bad prognosis. Six (40 %) needed a diet; 4 (50 %) laxatives or enemas and 1 (10 %) a cecostomy button for antegrade enemas. CONCLUSIONS: Patients with RvaF had a high index of associated anomalies. The difference of operative time was not statistically significative. No differences in functional results between both groups were observed. LT is a valid option to treat RvaF.

RESUMO

BACKGROUND: Assessment of postoperative bowel function in anorectal malformation (ARM) patients is crucial for benchmarking outcomes. We compared existing bowel function scoring systems in various aspects in patients with ARM. METHODS: With ethical approval, this was a cross-sectional study involving 5 paediatric surgery referral centres in Malaysia, comparing the Kelly, Japanese Study Group of Anorectal Anomalies (JSGA), Holschneider and Krickenbeck bowel function questionnaires. We recruited patients aged 4-17 years, who had completed definitive surgery & stoma closure (where relevant) > 12 months prior to participation. We standardised outcomes of each scoring system into categories ('good', 'fair', 'poor' and 'very poor') to facilitate comparison. Parents & patients were surveyed and asked to rate the ease of understanding of each questionnaire. The difference in protocol scores rated between parents and patients were compared. Association of each bowel function scoring protocol with type of anomaly was assessed. Statistical significance was p < 0.05. RESULTS: Thirty-nine parents (21 mothers, 18 fathers) and 23 patients were included in this study. Fair agreement was found between Kelly and Krickenbeck protocols (κ = 0.343; p < 0.001), between JSGA constipation and Holschneider protocols (κ = 0.276; p = 0.002); JSGA constipation and Krickenbeck protocols (κ = 0.256; p = 0.004); and between Holschneider and Krickenbeck protocols (κ = 0.273; p = 0.003). Only the Kelly protocol showed significant correlation between parents and patients' answers (ρ = 0.459, p = 0.028). Krickenbeck demonstrated the best negative correlation of patients' scores with ARM types (ρ = -0.401, p = 0.001). The Kelly protocol ranked highest when comparing ease of understanding. CONCLUSION: All the questionnaires appeared comparable in assessing postoperative faecal continence in ARM patients. The Kelly questionnaire performed best in 3 key areas of assessment. LEVEL OF EVIDENCE: Level III Cross-Sectional Study.

RESUMO

Due to the controversy on the feasibility of laparoscopic-assisted anorectoplasty (LAARP) for the treatment of the anorectal malformation (ARM) with rectobulbar fistula (RBF), this study aimed to compare the outcomes of LAARP and posterior sagittal anorectoplasty (PSARP) for ARM with RBF. Demographic data, postoperative complications, and bowel function of RBF patients who underwent LAARP and PSARP at 2 medical centers from 2016-2018 were retrospectively reviewed. Eighty-eight children with RBF were enrolled, including 43 in the LAARP group and 45 in the PSARP group. There were no significant differences in the sacral ratio (P = .222) or sacral agenesis (P = .374). Thirty-seven and 38 patients in the LAARP and PSARP groups were followed up for a median of 4.14 years. The postoperative complications were comparable between the groups (P = .624), with no cases of urethral diverticulum. The urination of all cases was normal and no evidence of cyst formation was found on MCU or MRI during the follow-up period. The incidence of rectal prolapse was similar between the 2 groups (9.3% vs 17.8%, P = .247). The groups had equivalent Bowel Function Score (15.29 ± 2.36 vs 15.58 ± 2.88, P = .645), but the LAARP group had better voluntary bowel movement (94.6% vs 84.2%, P = .148) by Krickenbeck classification. The intermediate-term outcomes of LAARP show that the urethral diverticulum was rare by the intraluminal incision of the fistular and the bowel function was comparable to that of PSARP in ARM with rectobulbar fistula. However, LAARP was associated with smaller perineal wounds.

RESUMO

Currarino syndrome is characterized by a triad of anorectal malformations, sacral defects, and presacral masses. Although it is not extremely rare, this report presents a surgical case of Currarino syndrome with syringomyelia and discusses related literature. The patient is a girl, aged 2 years and 2 months, who presented with marked constipation, chronic cystitis, and lower limb weakness. After examining the patient through magnetic resonance imaging, we diagnosed her with rectal compression due to meningocele and syringomyelia. The base of the meningocele was detached, and the spinal cord was untethered. One week after surgery, her lower limb weakness and constipation improved. Following up on symptoms and performing imaging is essential to determine a treatment plan for Currarino syndrome. (Received 28 February, 2023; Accepted 22 March, 2023; Published 1 August, 2023).

RESUMO

PURPOSE: To assess the number, characteristics, and functional short-, and midterm outcomes of patients with rectal atresia (RA) and stenosis (RS) in the ARM-Net registry. METHODS: Patients with RA/RS were retrieved from the ARM-Net registry. Patient characteristics, associated anomalies, surgical approach, and functional bowel outcomes at 1 and 5-year follow-up were assessed. RESULTS: The ARM-Net registry included 2619 patients, of whom 36 (1.3%) had RA/RS. Median age at follow-up was 7.0 years (IQR 2.3-9.0). Twenty-three patients (63.9%, RA n = 13, RS n = 10) had additional anomalies. PSARP was the most performed reconstructive surgery for both RA (n = 9) and RS (n = 6) patients. At 1-year follow-up, 11/24 patients with known data (45.8%, RA n = 5, RS n = 6) were constipated, of whom 9 required stool softeners and/or laxatives. At 5-year follow-up, 8/9 patients with known data (88.9%, RA n = 4, RS n = 4) were constipated, all requiring laxatives and/or enema. CONCLUSION: RA and RS are rare types of ARM, representing 1.3% of patients in the ARM-Net registry. Additional anomalies were present in majority of patients. Different surgical approaches were performed as reconstructive treatment, with constipation occurring in 46% and 89% of the patients at 1 and 5-year follow-up. However, accurate evaluation of long-term functional outcomes remains challenging.

RESUMO

BACKGROUND: The incidence and optimal management of rectal prolapse following repair of an anorectal malformation (ARM) has not been well-defined. METHODS: A retrospective cohort study was performed utilizing data from the Pediatric Colorectal and Pelvic Learning Consortium registry. All children with a history of ARM repair were included. Our primary outcome was rectal prolapse. Secondary outcomes included operative management of prolapse and anoplasty stricture following operative management of prolapse. Univariate analyses were performed to identify patient factors associated with our primary and secondary outcomes. A multivariable logistic regression was developed to assess the association between laparoscopic ARM repair and rectal prolapse. RESULTS: A total of 1140 patients met inclusion criteria; 163 (14.3%) developed rectal prolapse. On univariate analysis, prolapse was significantly associated with male sex, sacral abnormalities, ARM type, ARM complexity, and laparoscopic ARM repairs (p < 0.001). ARM types with the highest rates of prolapse included rectourethral-prostatic fistula (29.2%), rectovesical/bladder neck fistula (28.8%), and cloaca (25.0%). Of those who developed prolapse, 110 (67.5%) underwent operative management. Anoplasty strictures developed in 27 (24.5%) patients after prolapse repair. After controlling for ARM type and hospital, laparoscopic ARM repair was not significantly associated with prolapse (adjusted odds ratio (95% CI): 1.50 (0.84, 2.66), p = 0.17). CONCLUSION: Rectal prolapse develops in a significant subset of patients following ARM repair. Risk factors for prolapse include male sex, complex ARM type, and sacral abnormalities. Further research investigating the indications for operative management of prolapse and operative techniques for prolapse repair are needed to define optimal treatment. TYPE OF STUDY: Retrospective cohort study. LEVEL OF EVIDENCE: II.

RESUMO

BACKGROUND: Anorectal malformations (ARM) are associated with neurogenic bladder. The traditional surgical ARM repair is a posterior sagittal anorectoplasty (PSARP), which is believed to have a minimal effect on bladder dynamics. However, little is known about the effects of reoperative PSARP (rPSARP) on bladder function. We hypothesized that a high rate of bladder dysfunction existed in this cohort. METHODS: We performed a retrospective review of ARM patients undergoing rPSARP at a single institution from 2008 to 2015. Only patients with Urology follow-up were included in our analysis. Data was collected regarding original level of ARM, coexisting spinal anomalies and indications for reoperation. We assessed urodynamic variables and bladder management (voiding, CIC or diverted) before and after rPSARP. RESULTS: A total of 172 patients were identified, of which 85 met inclusion criteria with a median follow-up of 23.9 months (IQR, 5.9-43.8 months). Thirty-six patients had spinal cord anomalies. Indications for rPSARP included mislocation (n = 42), posterior urethral diverticulum (PUD; n = 16), stricture (n = 19) and rectal prolapse (n = 8). Within 1 year following rPSARP, 11 patients (12.9%) had a negative change in bladder management, defined as need for beginning intermittent catheterization or undergoing urinary diversion, which increased to 16 patients (18.8%) at last follow-up. Postoperative bladder management changed in rPSARP patients with mislocation (p < 0.0001) and stricture (p 0.005) but not for rectal prolapse (p 0.143). CONCLUSIONS: Patients who undergo rPSARP warrant especially close attention for bladder dysfunction as we observed a negative postoperative change in bladder management in 18.8% of our series. LEVEL OF EVIDENCE: Level IV.

RESUMO

PURPOSE: To provide a high-fidelity, animal tissue-based model for the advanced surgical simulation of a Posterior Sagittal Anorectoplasty (PSARP) for rectovestibular fistula in anorectal malformation (ARM). MATERIALS AND METHODS: A chicken cadaver was used to assess the feasibility of simulating a PSARP for rectovestibular fistula in ARM. No modification was required to implement the surgical simulation. RESULTS: A detailed description of the high-fidelity surgical simulation model is provided. The PSARP can be simulated while providing realistic anatomy (e.g. common wall between rectovestibular fistula and vagina), adequate rectal size, location and placement of the rectovestibular fistula, and proximity to the vagina. Haptic conditions of the tissue resemble human tissue and operative conditions as well. DISCUSSION: Concerning the decreased exposure of index cases of pediatric surgical trainees and pediatric surgeons in practice, simulation-based training can provide means to acquire or maintain the necessary skills to perform complex surgical procedures [1-5] Surgical simulation models for ARM are limited. Few low-cost trainers are available with predominant artificial and mostly unrealistic tissue [6-8] Animal models have the advantage of realistic multilayer tissue haptic feedback [6]. CONCLUSION: We provide a low-cost, high-fidelity model for correcting a rectovestibular fistula in a child with ARM, a complex operative procedure with low incidence but high-stake outcomes. The described tissue model utilizing the chicken cloaca anatomy provides a high-fidelity model for operative correction of rectovestibular ARM. For simulation purposes in the treatment of ARM, this model appears to be promising in terms of providing realistic pathology and haptic feedback in pediatric dimensions. LEVEL OF EVIDENCE: V.

RESUMO

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. LEVEL OF EVIDENCE FOR CLINICAL RESEARCH PAPERS: Level Ⅳ. TYPE OF STUDY: Treatment study.

RESUMO

Introduction: Anal dilation with Hegar dilator is recommended as part of the post-operative management following surgical correction of anorectal malformation (ARM) in children to prevent strictures. Parents usually continue dilation at home with a personal set of dilators. However, in low-resource settings, many parents cannot afford the Hegar dilator. Devices that have been improvised as dilators include appropriately sized candles, spigot from Foley catheter, rounded ball pen ends and mothers' fingers. We aimed to report our preliminary experience with the use of candle as an improvised anal dilator following surgeries for ARM in our practice. Materials and Methods: A review of records of children who had surgery for ARMs and commenced on candle dilation between February 2018 and July 2019 at our centre was done. Relevant demographic information, type of anomaly, duration of dilation, availability of health insurance coverage, complications and parents' acceptance of improvised dilator (evaluated during scheduled follow up visits) were retrieved. The data were analysed using SPPSS version 21 (Chicago, Illinois). Results: Nineteen patients underwent anal dilation with improvised candles during the period. Rectobulbar and rectovestibular fistulas were most frequent anomaly in boys and girls, respectively. The median age at surgery was 6 months. The median duration of dilation (completed in 9 patients) was 7 months. Candle dilation was well tolerated, and all parents were comfortable using the device. Conclusion: The candle as an improvised anal dilator following anorectal surgeries in children is a useful alternative to the conventional dilator. It is more affordable and gives satisfactory results.

RESUMO

OBJECTIVE: To study the influence of gene methylation in the Shh/Bmp4 signaling pathway on the enteric nervous system in the rectum of rat embryos with anorectal malformations (ARMs). METHODS: Pregnant Sprague Dawley rats were divided into three groups; two groups treated with either ethylene thiourea (ETU induce ARM) or ETU+5-azacitidine (5-azaC inhibit DNA methylation) and a normal control group. The levels of DNA methyltransferases (DNMT1, DNMT3a, DNMT3b), the methylation status of the Shh gene promoter region and the expression of the key components were detected by PCR, immunohistochemistry and western blotting. RESULTS: The expression of DNMTs in the rectal tissue of the ETU and ETU+5-azaC groups was higher than that of the control. The expression of DNMT1, DNMT3a and methylation level of the Shh gene promoter in the ETU group was higher than in the ETU+5-azaC group (P < 0.01). The methylation level of the Shh gene promoter was higher in the ETU+5-azaC group than in the control. The Shh and Bmp4 expression in the ETU and ETU+5-azaC groups were lower than in the control, and their expression in the ETU group was also lower than in the ETU+5-azaC group. CONCLUSION: The methylation status of genes in the rectum of the ARM rat model may be changed by intervention. The low methylation level of the Shh gene may promote the expression of key Shh/Bmp4 signaling pathway components.

RESUMO

Anorectal malformations (ARMs) are a spectrum of congenital anomalies where there is abnormal development of the anus and rectum. With an incidence of 1:5000 live births and affecting both males and females, these anomalies vary in their appearance and presentation, lack features enabling antenatal detection and should be detected at birth by the examining midwife or within 72 hours through the newborn and infant physical examination (NIPE) screening programme. However, it is recognised that the diagnosis of ARMs can be missed or delayed leading to morbidity and mortality. In the UK, despite the existence of the NIPE screening programme and NICE guidelines, published literature shows that nearly a quarter of ARMs are not diagnosed at birth. This review takes a critical look at the frequency of missed/delayed diagnosis of ARMs at birth, the implications of delayed diagnosis, and the possible reasons for this related to education and training of healthcare professionals involved in newborn examination, focusing on the UK national screening programme for NIPE. We propose a strategy for enhancing detection of ARMs in a timely manner through the existing framework of the NIPE screening programme.

RESUMO

INTRODUCTION: Rectal atresia is a rare subtype of anorectal malformations in which the patients are born with a normal anal canal but have complete atresia located few centimeters proximal to the dentate line. We present the transanal end-to-end rectoanal anastomosis as a surgical technique for the management of these patients, highlight the outcomes, and emphasize on some clinical tips. METHODS: Four patients were diagnosed as having rectal atresia on clinical and radiological basis. All of them underwent single loop low sigmoid colostomy in the first 24 h. After 6 months, transanal end-to-end rectoanal anastomosis was performed followed by closure of the stoma 3 months later. RESULTS: The 2 cases that are older than 3 years demonstrated normal continence and are clean between bowel movements, while the other two showed good anal tone and passing stools between 1-3 times daily, being dry in between. CONCLUSION: Transanal recto-anal anastomosis allows a safer route of anatomical reconstruction of the anorectum, therefore avoiding the potential complications associated with the other more invasive approaches.

RESUMO

Anorectal malformations (ARM) in females are identified by abnormal location of the anal opening. Management is guided by clinical examination to find the number of perineal openings. Two openings in the perineum of a female may be seen in cases of imperforate anus without fistula, vaginal agenesis with vestibular fistula or imperforate anus with recto-vaginal fistula (RVF). We present a case series of ARM with RVF and discuss their diagnosis and management.
