Abstract
INTRODUCTION Postoperative constipation (PC) in patients with imperforate anus and perineal fistula (PF) has been reported in up to 60%. Histological studies of PF revealed innervation anomalies which seem to be one of the reasons for PC. Perioperative histologically controlled fistula resection (PHCFR) allows appropriate resection of PF and pull-down normoganglionic rectum at the time of posterior sagittal anorectoplasty (PSARP). MATERIALS AND METHODS A total of 665 patients with anorectal malformations underwent surgery between 1991 and 2021. Of these, 364 presented PF; 92 out of them (41 F) were studied. Patients with sacral and spinal cord anomalies, neurological disorders, and cut-back anoplasty were excluded. PSARP was done on all patients. Hematoxylin-eosin staining and NADH Tetrazolium-reductase histochemical method were used. Four and more ganglion cells in the myenteric plexus represented a sufficient length of the resection. The continence was scored according to the modified Krickenbeck scoring system. Final scores ranged from 1 to 7 points. Values are given as median. RESULTS A total of 65 (70.7%) patients presented an aganglionic segment in PF, and 27 patients presented hypoganglionosis. The median length of the resected fistula was 25 mm (interquartile range [IQR]: 20-30). The median total continence score was 7 (IQR: 6-7). Post-op constipation was observed in 6/92 (6.5%) patients. CONCLUSION PHCFR diminished PC to 6.5% of patients.

Abstract
Anorectal malformation (ARM), a common congenital anomaly of the digestive tract, is a result of insufficient elongation of the urorectal septum. The cytoplasmic protein Receptor of Activated C-Kinase 1 (Rack1) is involved in embryonic neural development; however, its role in embryonic digestive tract development and ARM formation is unexplored. Our study explored the hindgut development and cell death mechanisms in ARM-affected rats using spatial transcriptome analysis. We induced ARM in rats by administering ethylenethiourea via gavage on gestational day (GD) 10. On GDs 14-16, embryos from both normal and ARM groups underwent spatial transcriptome sequencing, which identified key genes and signalling pathways. Rack1 exhibited significant interactions among differentially expressed genes on GDs 15 and 16. Reduced Rack1 expression in the ARM-affected hindgut, verified by Rack1 silencing in intestinal epithelial cells, led to increased P38 phosphorylation and activation of the MAPK signalling pathway. The suppression of this pathway downregulated Nqo1 and Gpx4 expression, resulting in elevated intracellular levels of ferrous ions, reactive oxygen species (ROS) and lipid peroxides. Downregulation of Gpx4 expression in the ARM hindgut, coupled with Rack1 co-localisation and consistent mitochondrial morphology, indicated ferroptosis. In summary, Rack1, acting as a hub gene, modulates ferrous ions, lipid peroxides, and ROS via the P38-MAPK/Nqo1/Gpx4 axis. This modulation induces ferroptosis in intestinal epithelial cells, potentially influencing hindgut development during ARM onset.

Abstract
OBJECTIVE Wound dehiscence after posterior sagittal anorectoplasty (PSARP) or anorectal vaginal urethroplasty (PSARVUP) for anorectal malformation (ARM) is a morbid complication. We present a novel anoplasty technique employing para-U-stitches along the anterior and posterior portions of the anoplasty, which helps buttress the midline U-stitch and evert the rectal mucosa. We hypothesized that, in addition to standardized pre- and postoperative protocols, this technique would lower rates of wound dehiscence. MATERIALS AND METHODS A retrospective review of patievnts who underwent primary PSARP or PSARVUP with the para-U-stitch technique from 2015 to 2021 was performed. Wound dehiscence was defined as wound disruption requiring operative intervention within 30 days of the index operation. Superficial wound separations were excluded. Descriptive statistics were calculated. The final cohort included 232 patients. RESULTS Rectoperineal fistula (28.9%) was the most common ARM subtype. PSARP was performed in 75% and PSARVUP in 25%. The majority were reconstructed with a stoma in place (63.4%). Wound dehiscence requiring operative intervention occurred in four patients, for an overall dehiscence rate of 1.7%. The dehiscence rate was lower in PSARPs compared with PSARVUPs (0.6 vs. 5.2%) and lower for reconstruction without a stoma compared with a stoma (1.2 vs. 2.0%). There were additional six patients (2.6%) with superficial wound infections managed conservatively. CONCLUSION We present the para-U-stitch anoplasty technique, which is an adjunct to the standard anoplasty during PSARP and PSARVUP. In conjunction with standardized pre- and postoperative protocols, this technique can help decrease rates of wound dehiscence in this patient population.

Abstract
Aims and Objectives Complications following posterior sagittal anorectoplasty (PSARP) for ARM are well known. In this article, we present our experience of managing five patients who required major redo surgeries for complications resulting from previous attempts to correct ARM. Materials and Methods We reviewed all patients who underwent major redo surgeries in our hospital for complications from previous repairs for ARM, from June 2013 to June 2019. Data was obtained from hospital records and analysed. Results Five patients whose ages ranged from 5 months to 14 years were included in the study. Four were boys and 1 was a girl. All patients had undergone PSARP in other hospitals. The presentations were retained distal bowel causing urinary retention and constipation (n=1), pulled through proximal urethra and bladder neck presenting as passage of urine from neo-anus (n=1), retained common channel (of cloaca) causing a 'H' type configuration (n=1), mispositioned neo-anus (n=1) following a primary PSARP and lastly undivided recto-urethral fistula causing fecaluria (n=1). All of them underwent redo repairs by posterior sagittal approach with documented improvement in their symptoms. Two of them required total bowel management to remain clean. Conclusion All the complications reported here have been described in literature nevertheless, this report will add to the body of experience. Posterior sagittal approach (PSA) has proved to be very successful technique in correcting these complications.

Abstract
Anorectal malformations (ARMs) comprise a broad spectrum of congenital anomalies involving both anorectal and urogenital tracts. After diagnosis, urological problems should be evaluated in addition to surgical correction of ARMs. Commonly encountered urological problems in patients with ARMs are recurrent urinary tract infections, vesicoureteral reflux, and chronic kidney disease. Therefore, the proper timing of urination and appropriate defecation habits are essential for preserving renal function in patients with ARMs. Here, we report a case of acute hydronephrosis by severe stool impaction in a patient with a history of congenital ARMs and neurogenic bladder. In this case, the physicians should consider properly managing chronic constipation and urination in patients with ARMs despite successful surgical corrections.

Abstract
Congenital anorectal malformation (ARM) is a diverse group of anomalies affecting the development of the anal and rectal regions, with an estimated incidence of one in every 5000 live births. The colostomy is commonly performed as part of the staged management of children with ARM to prevent complications. However, the presence of acute watery diarrhea in children with ARM and colostomy poses significant management challenges due to the altered anatomy and physiology affecting stool regulation and absorption, exacerbated by various factors including infections, dietary issues, medication side effects, and underlying gastrointestinal complications.This case study explores the complexities involved in managing acute watery diarrhea in children with congenital ARM and colostomy. A comprehensive literature review was conducted to examine the existing evidence on the subject. The study highlights the multidisciplinary approach required, involving pediatricians, surgeons, and other specialists, to provide comprehensive care and support for these children. Effective management of acute watery diarrhea in children with congenital ARM and colostomy necessitates collaboration between pediatricians and surgeons. Pediatricians play a crucial role in assessing hydration status, monitoring electrolyte balance, and providing appropriate fluid and nutritional management. Surgeons address the surgical aspects of care and coordinate interventions with the management of acute diarrhea. The study underscores the importance of a multidisciplinary approach to deliver comprehensive care, optimize outcomes, and improve the quality of life for affected children. The management of acute watery diarrhea in children with congenital ARM and colostomy presents significant challenges due to the complex interplay of anatomical, physiological, and clinical factors. A multidisciplinary approach involving pediatricians, surgeons, and other specialists is vital for providing comprehensive care and support. This case study emphasizes the need for further research, guidelines, and collaborative efforts to enhance the management strategies for this vulnerable population.

Abstract
Purpose Prone cross-table lateral x-ray (CTLxR) and colostogram aid surgical planning for anorectal malformations (ARMs) without perineal fistulas. We suggest objective imaging tools to classify ARMs. Methods Three observers prospectively evaluated CTLxR and colostograms of male ARM patients (2012-2022) without perineal fistulas. The level of the rectal pouch was estimated with pubococcygeal (PC) and ischiatic (I) lines. On CTLxR, we described the "pigeon sign", defined as the rectal pouch ending with a beak-like image, suspicious for a rectourinary fistula. ARM was defined as rectobulbar when the rectal pouch was below the I line, rectoprostatic when between PC and I lines, and rectovesical when above the PC line. Concordance was assessed with Fleiss' kappa. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the "pigeon sign" were calculated. Results Thirteen patients were included in this study. The interobserver agreement on CTLxR was 69.2% (k = 0.54) on pouch ending, 84.6% (k = 0.69) on the "pigeon sign", and 76.9% (k = 0.69) on diagnosis; concordance between observers and intraoperative diagnosis was 66.6% (k = 0.56). The "pigeon sign" had 75% sensitivity, 100% specificity, 100% PPV, and 50% NPV. The interobserver agreement on colostograms was 84.6% (k = 0.77) on pouch ending and 89.7% (k = 0.86) on diagnosis; concordance between observers and intraoperative diagnosis was 92.3% (k = 0.90). Conclusion PC and I lines and the "pigeon sign" are useful tools in examining CTLxR and colostograms. Adequate CTLxR interpretation may modify surgical strategy.

Abstract
Background We aimed to evaluate the function of the reconstructed anal canal in postoperative anorectal malformations (ARMs) patients through three dimension (3D) high-definition anorectal manometry. Methods From January 2015 to December 2019, 3D manometry was performed as a postoperative functional assessment of patients with ARMs divided into age subgroups based on the time of manometry. Manometric parameters, such as the length of the anorectal high-pressure zone (HPZ-length), the mean resting and squeeze pressure of HPZ (HPZ-rest and HPZ-sqze), recto-anal inhibitory reflex (RAIR), and strength distribution of the anal canal, were collected and compared with age-matched controls. Their functional outcomes were analyzed with SPSS 23.0 software for statistical analysis. Results 171 manometric measurements were performed on 142 postoperative patients (3 months∼15 years). The HPZ-rest in all patients was significantly lower than in age-matched controls (p < 0.05). HPZ-sqze was notably decreased in patients older than 4 years, whereas other age groups were comparable to controls (p < 0.05). The proportions of asymmetric strength distribution and negative RAIR were higher in ARMs patients. The type of anorectal malformations and lower HPZ-rest were the impact factors affecting postoperative functional outcomes. Conclusions The majority of the ARMs patients had acceptable functional outcomes. 3D manometry can objectively assess the reconstructed anal canal function. The patients with fecal incontinence had a high proportion of extremely low HPZ-rest and HPZ-sqze, negative RAIR, and asymmetric strength distribution. The manometric details will help the clinicians explore the causes of defecation complications and guide further management.

Abstract
INTRODUCTION The objective of this study is to assess the postoperative outcomes of single-stage repair of anorectal malformations with vestibular (VF) or perineal fistula (PF) and early initiation of postoperative feeding. METHODS A retrospective review of patients undergoing single-stage repair of isolated low anorectal malformations (VF and PF) from 2017 to 2020 was conducted. All patients underwent an anterior anoplasty with complete mobilization of the rectal fistula, or posterior sagittal anorectoplasty (PSARP), without protective colostomy. The variables examined include age, timing of postoperative feeding initiation, length of stay (LOS), and complications. RESULTS Nineteen patients with VF or PF underwent a single-stage repair. 12/19 (63%) patients were female. All 7 males and 9/12 females had a PF. The range of age at surgery was 2 days to 3 years with median age of 92 days [IQR 1,3: 9,193]. The median postoperative day for initiation of feeds was day 0 [IQR 1,3: 0,1] and median LOS was 1 day [IQR 1,3: 1,4.5]. 18/19 (95%) patients were evaluated in follow-up and there were no wound infections, wound dehiscences, or recurrent fistulas. Within 90 days postoperatively, no patients were seen in the emergency department for postoperative issues. Within 6 months, 2/19 (11%) patients required an unplanned return to the operating room for anal dilation. CONCLUSION In single-stage repair of isolated low anorectal malformations, VF and PF, early initiation of postoperative feeding is safe, results in a short length of stay, and does not lead to increased wound complications. Early enteral feeding eliminates the need for parenteral nutrition and central venous access, and their associated complications. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND End stage renal disease (ESRD) requiring kidney transplant (KT) remains an important cause of morbidity in anorectal malformations (ARM) patients. Current literature is scarce on defining the risk factors for ESRD and the outcomes of KT in ARM patients. OBJECTIVE This study aimed to identify predisposing factors to ESRD in ARM patients and verify if the long term outcome of KT in these patients differs from pure urological anomalies (UA). STUDY DESIGN Databases of ARM and KT patients treated at our center between 2000 and 2016 were used for comparing characteristics of ARM cases which developed ESRD and those who did not, and the outcome features of MAR-KT vs UA-KT. RESULTS Out of 117 ARM patients, 9 developed ESRD. All of them had a complex ARM. Association with UA were significantly higher in ARM-KT compared to other ARM patients (100% vs. 52%, p = 0.001). The most common UA associated to KT in ARM patients was renal dysplasia. During the same period 23 patients underwent KT as a sequelae of pure urological anomalies (UA-KT group). The most represented UA were primary vesico-ureteral reflux (65.2%) and posterior urethral valves (14%) in UA-KT (table 2). ARM-KT patients required more often hemodialysis before KT (50% vs. 8.7%, p = 0.05) and an aorto-caval anastomosis at the transplant (75% vs. 30%, p = 0.04) compared to UA-KT. Moreover ARM-KT patients experienced more often graft failure and and the need for a second KT (50% vs. 8.6%, p = 0.02). DISCUSSION To our knowledge, this is the first study describing the differences in terms of risk factors and outcomes of KT in ARM patients. We observed a need for KT in 7% of ARM, which is at the higher end of the range reported in the literature. Bilateral dysplasia and cloaca malformation seem the leading cause to ESRD for ARM patients compared to vesico-ureteral reflux and posterior urethral valve in UA-KT. Our experience showed that KT has worst outcome in ARM vs pure UA patients. CONCLUSION Patients with complex ARM are more frequently associated to renal dysplasia which lead to KT. Graft in ARM patients seems to be the more vulnerable and prone to failure.

Abstract
Anorectal malformations (ARMs) are the most common gastrointestinal malformations. miR-141-3p was obtained from whole-transcriptome sequencing, and Ub domain-containing protein 2 (Ubtd2) was predicted as the target gene. An ARM rat model was induced using ethylenethiourea. Fluorescence in situ hybridization and immunofluorescence were used to detect the spatiotemporal expression of miR-141-3p and Ubtd2, respectively. A dual-luciferase reporter assay confirmed their targeting relationship, and cell proliferation and apoptosis were investigated after transfection in the intestinal epithelium (IEC-6). Additionally, western blotting and co-immunoprecipitation were used to examine the protein levels and the endogenous binding relationship. miR-141-3p was downregulated in the ARM group, whereas Ubtd2 increased and colocalized with TUNEL-positive cells. After miR-141-3p inhibition, protein expression of USP5 and β-catenin was affected via Ubtd2, and USP5 could bind to both Ubtd2 and β-catenin. Flow cytometry analysis and caspase 3/7 staining demonstrated that downregulated miR-141-3p promoted cell apoptosis through Ubtd2. In summary, targeting Ubtd2 decreased in miR-141-3p and promoted apoptosis of intestinal epithelium and regulated β-catenin expression. This may cause aberrant apoptosis during hindgut development and mediate the imbalance of β-catenin signaling in the cloaca, further affecting the occurrence of ARMs.

Abstract
Purpose The aim of the study is to explore the impact of perioperative pain care management on patients' pain, comfort, and defecation in anorectal surgery. Methods From January to December 2021, 126 patients who underwent anorectal surgery in our department were selected for the study and were randomly divided into a study group and a control group of 63 patients each after consent was obtained from the patients. The control group was given the usual care protocol and the study group was given the perioperative pain care management on top of the usual care. The two groups of patients were compared in terms of postoperative anal pain rating, comfort score, time to first bowel movement and time spent in bowel movement, the Pittsburgh sleep quality index (PSQI) scores at night, related complications, and satisfaction with care. Results ① Postoperative anal pain was less severe in the study group than in the control group (P < 0.05). ② Postoperative comfort scores were higher in the study group than in the control group (P < 0.05). ③ The time to first bowel movement and its duration after surgery were shorter in the study group than in the control group (P < 0.05). ④ Patients in the study group had lower postoperative night-time PSQI scores than the control group (P < 0.05). ⑤ Patients in the study group had a lower rate of postoperative complications than the control group (P < 0.05). ⑥ Patients in the study group had higher postoperative care satisfaction scores than the control group (P < 0.05). Conclusion The application of perioperative pain care management to patients undergoing anorectal surgery plays an important role in reducing anal pain, improving treatment comfort, and relieving difficult defecation symptoms, with significant improvement in postoperative sleep quality and reduction in complications. It is worthy of clinical reference and promotion.

Percutaneous Anorectoplasty (PARP)—An Adaptable, Minimal-Invasive Technique for Anorectal Malformation Repair. CHILDREN 2022; 9:children9050587. [PMID: 35626764 PMCID: PMC9140123 DOI: 10.3390/children9050587] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 04/13/2022] [Accepted: 04/19/2022] [Indexed: 12/18/2022]
Abstract
Background: Anorectal malformations comprise a broad spectrum of disease. We developed a percutaneous anorectoplasty (PARP) technique as a minimal-invasive option for repair of amenable types of lesions. Methods: Patients who underwent PARP at five institutions from 2008 through 2021 were retrospectively analyzed. Demographic information, details of the operative procedure, and perioperative complications and outcomes were collected. Results: A total of 10 patients underwent the PARP procedure during the study interval. Patients either had low perineal malformations or no appreciable fistula. Most procedures were guided by ultrasound, fluoroscopy, or endoscopy. Median age at PARP was 3 days (range 1 to 311) days; eight patients were male. Only one intraoperative complication occurred, prompting conversion to posterior sagittal anorectoplasty. Functional outcomes in most children were highly satisfactory in terms of continence and functionality. Conclusions: The PARP technique is an excellent minimal-invasive alternative for boys born with perineal fistulae, as well as patients of both sexes without fistulae. The optimal type of guidance (ultrasound, fluoroscopy, or endoscopy) depends on the anatomy of the lesion and the presence of a colostomy at the time of repair.

Abstract
Reconstructive techniques for complex anorectal malformations (ARMs) require intestinal pull-through on vascular pedicles. Traditionally, the visual inspection of the intestinal perfusion is the sole modality adopted to assess tissue viability. In this article, we report the case of a child with a rectourethral prostatic fistula, who had a Peña's descending colostomy with distal mucous fistula in the neonatal period and a posterior sagittal anorectoplasty at 6 months of life. The ARM repair was guided by indocyanine green (ICG), which was intravenously administered to evaluate the blood flow of the intestinal pull-through using the EleVision IR system (Medtronic Ltd, U.K.). ICG-based fluorescence-guided surgery helped to define the proximal resection margin, impacting intraoperative decision making, and no postoperative complications occurred. We envisage that this technology will become part of the armory of pediatric surgeons soon, by reducing the risk of intra- and postoperative complications.

Abstract
Currently accepted primary repair of congenital anorectal malformations (ARMs) includes a posterior sagittal incision, which allows for optimal visualization and identification of important pelvic structures and anatomical features. Reconstructive surgery involves meticulous dissection and separation of pelvic structures, and careful reconstruction can result in good functional outcomes for many patients, who live without ongoing sequelae from their malformation. However, some patients may require reoperative procedures for anatomic or functional reasons. Males and females present with slightly different symptoms and should be approached differently. Males are most likely to require reoperations for anorectal or urethral pathologies, but the urinary system is often spared in females-they instead must contend with Mullerian duct anomalies, of which there are many varieties. Depending on the original malformation and severity of symptoms, redo surgery may be needed to optimize function and quality of life. Surgical management with reoperative surgery in ARMs ranges from straightforward to complex, depending on the issue. One must weigh the risks of reoperative surgery and potentially creating more scarring against the need for a better anatomical and functional outcome. Current management trends and practice patterns with regards to reoperative surgery in ARM patients are not widely studied or standardized but we provide an overview of the more common pathologies, preoperative evaluation and workup required to identify the issues, and options for reoperative repair in these patients.

Abstract
PURPOSE To report the sequelae of and preventive strategies for selected lower urinary tract (LUT) complications, i.e., posterior urethral diverticulum (PUD), intraoperative LUT injuries, postoperative dysuria, and fistula recurrence in male imperforate anus (IA) with rectourethral/rectovesical (RU/RV) fistula after laparoscopy-assisted anorectoplasty (LAARP) or posterior sagittal anorectoplasty (PSARP). METHODS 153 boys with IA and RU/RV fistula treated 1986-2019 by LAARP (n = 56) or PSARP (n = 97) at two unrelated institutes were studied retrospectively. RESULTS After mean follow-up of 17.0 years (range: 36.5 days-32.0 years), the overall incidences of LUT complications were: LAARP (6/56; 10.7%); PSARP (7/97; 7.2%); p = 0.55, comprising PUD: LAARP (n = 5), PSARP (n = 0); p = 0.006; injuries: LAARP (n = 0), PSARP (n = 5); p = 0.16; dysuria: LAARP (n = 1), PSARP (n = 1); p>0.999; and recurrence: LAARP (n = 0), PSARP (n = 1); p>0.999. Mean onset of PUD was 5.1 years (range: 1.0-15.1 years). TREATMENT PUD: surgery (n = 2/5), conservative (n = 3/5); injuries: intraoperative repair (n = 5/5); dysuria: conservative (n = 2/2), and recurrence: redo PSARP (n = 1/1). CONCLUSIONS Strategies devised to improve dissection accuracy resolved the specific technical issues causing LUT complications (remnant RU fistula dissection in LAARP and blind posterior access in PSARP). Currently, the incidence of new cases of PUD and LUT injuries is zero. LEVEL OF EVIDENCE Level III.

Abstract
Anorectal malformation includes various types of anomalies. The goal of definitive surgery is achievement of fecal continence. Twenty years have passed since laparoscopically assisted anorectoplasty (LAARP) was reported by Georgeson. Since LAARP is gaining popularity, its long-term outcomes should be evaluated. Presently, there is no evidence regarding the optimal method of ligating and dividing the fistula correctly and creating the pull-through canal accurately. Rectal prolapse and remnant of the original fistula (ROOF) tend to develop more often in LAARP patients than in posterior sagittal anorectoplasty (PSARP) patients; however, robust evidence is not available. Prolapse may be prevented by suture fixation of the rectum to the presacral fascia; however, if prolapse occurs, the indication, timing, and the best method for surgical correction remain unclear. Most patients with ROOF are asymptomatic, and there is controversy regarding the indications for ROOF resection. This article aimed to detail the various modifications of the LAARP procedures reported previously and to describe the surgical outcomes, particularly focusing on rectal prolapse, ROOF, and fecal continence, by reviewing the literature. Functional outcomes after LAARP were almost similar to those noted after PSARP, and we have demonstrated that LAARP is not inferior to PSARP with respect to fecal continence. Although there is controversy regarding the application of LAARP for recto-bulbar cases, we believe that LAARP is still evolving, and we can achieve better outcomes by improving the procedure.

Abstract
Vaginal agenesis is a complex pediatric condition that lead to long-term urinary, gastrointestinal, and sexual dysfunction. A meticulous physical examination and in-depth diagnostic investigations are necessary to determine the appropriate surgical management. Reconstruction of neovagina can be retrieved from the ileum.
Vaginal agenesis with anorectal malformations is a complex pediatric condition that adversely affects various physiological processes in the body. It may cause disturbances in defecation and urination, abnormalities in the urinary and gastrointestinal tract, dysfunction of the genital and reproductive organs, and sexual function disorders. The complexity in the surgical management of vaginal agenesis includes the selection of a functional reconstruction technique for anal and vaginal formation, timing of the reconstruction, and management of complications in the associated organ system. Herein, we describe a patient with Mayer–Rokitansky–Küster–Hauser syndrome accompanied by a rectovesical fistula. Other abnormalities, such as microcephaly, polydactyly, long urethral abnormalities resembling the male urethra, and complications in the kidney and urinary tract, were observed in the patient. The associated complications included recurrent urinary tract infections, urinary overflow incontinence, vesicoureteric reflux, hydroureter, and left renal hydronephrosis. The patient underwent posterior sagittal anorectoplasty surgery and vaginal reconstruction. The long-term vaginal physiological development of patients with this condition remains unknown.

Abstract
Aim: To clarify the characteristics of patients with rectal prolapse after laparoscopically assisted anorectoplasty (LAARP), estimate the causes, and evaluate its impact on postoperative bowel function. Methods: The medical records of patients who underwent LAARP for high- or intermediate-type anorectal malformation between 2000 and 2019 were retrospectively reviewed. Clinical data were compared between patients with (Group P) and without prolapse (normal, Group N). Fecal continence was evaluated using the clinical assessment score for fecal continence developed by the Japanese Study Group of Anorectal Anomalies. For patients who underwent pelvic magnetic resonance imaging (MRI) before LAARP, atrophy, or asymmetry of the anal sphincter and levator ani was evaluated by a radiologist. Results: Of the 49 patients, 29 (59%) had rectal prolapse after LAARP (Group P) and 20 did not (Group N). We found no significant difference in gender, type of malformations, incidence of associated spinal or lumbosacral anomalies, procedure time, and postoperative bowel function at ages 4, 8, 12, and 16 years. However, LAARP was performed significantly earlier in Group N (median [range], 180 [123-498] days) than in Group P (210 [141-570] days). In Group P, 18 patients (62%) developed prolapse before colostomy takedown. Eight of 26 patients who underwent surgical prolapse repair required redo procedures. Twenty-five patients who underwent preoperative pelvic MRI showed no significant relationship between the muscular abnormalities and the incidence of postoperative rectal prolapse. Conclusions: Although recurrence is common, performing LAARP at a younger age might prevent postoperative prolapse development.
