Meta-Analysis Review
OBJECTIVE
The laparoscopically-assisted anorectal pull-through (LAARP) for recto-bladderneck and recto-prostatic anorectal malformations (RB/RP-ARMs) is believed to improve patient outcomes. We performed a systematic review of the effect of LAARP on postoperative mucosal prolapse and defecation dysfunction.
METHODS
A comprehensive search of MEDLINE, EMBASE, CENTRAL, and grey literature was performed (2000-2014). Full-text screening, data abstraction and quality appraisal were conducted in duplicate. Included studies reported a primary diagnosis of RB/RP-ARM and compared LAARP versus open repair (OPEN).
RESULTS
From 3681 retrieved articles, 7 studies enrolling 187 patients were analyzed. One was a randomized control trial, 6 were retrospective observational studies, and all were single-centre. The majority were of poor-moderate quality (MINORS scores: mean 16.42 (SD 2.225) out of 24). Mucosal prolapse was not significantly different after LAARP versus OPEN (p = 0.18). Defecation outcomes were inconsistently reported but were no different between LAARP and OPEN for either children >3 years old (p = 0.84), or all ages combined (p = 0.11).
CONCLUSION
We found no significant difference in rates of mucosal prolapse or defecation scores for LAARP compared to OPEN for children with RB/RP-ARMs. However, studies are small and of poor-moderate quality and results are heterogeneous. Comprehensive, standardized, reliable reporting is necessary to guide practice and inform postoperative guidelines.

Review
BACKGROUND
Children with anorectal malformations may experience constipation and fecal incontinence following repair. The contribution of altered anorectal function to these persistent symptoms is relatively intuitive; however, colonic motility in this cohort is less well understood. Manometry may be used to directly assess colonic motility.
PURPOSE
The purpose of this systematic review was to synthesize the available evidence regarding post-operative colonic motility in children with anorectal malformations and evaluate the reported equipment and protocols used to perform colonic manometry in this cohort. This systematic review was conducted in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We conducted a systematic review of four databases: Embase, MEDLINE, PubMed, and the Cochrane Library (1 January 1985-22 July 2021). Studies reporting colonic manometry performed in children following anorectal malformation repair were assessed for eligibility. Data were extracted independently by two authors. Four studies were eligible for inclusion. Of the combined total cohort of 151 children, post-operative colonic manometry was conducted in 35. Insufficient reporting of medical characteristics, bowel function, and manometric outcomes restricted comparison between studies, and limited clinical applicability. No results from high-resolution colonic manometry were identified. Despite the prevalence of post-operative bowel dysfunction in children with repaired anorectal malformations, this systematic review highlighted the markedly limited evidence regarding post-operative colonic motility. This cohort may benefit from assessment with high-resolution techniques; however, future work must emphasize adherence to standardized manometry protocols, and include robust reporting of surgical characteristics, bowel function, and manometric outcomes.

Review
INTRODUCTION
Laparoscopic-assisted anorectal pull-through (LAARP) is becoming an increasingly common procedure to correct high and intermediate anorectal malformations (ARMs). The aim of this review was to evaluate worldwide experiences with LAARP with regard to indications, outcomes, and quality of reporting.
METHOD
A systematic review was conducted. The search was limited to studies reported in English and performed in humans. In addition to Medline and PubMed, a manual search of the Journal of Pediatric Surgery, Pediatric Surgery International, Surgical Endoscopy, and the Journal of Laparoendoscopic & Advanced Surgical Techniques published between June 2000 and April 2008 was conducted.
RESULTS
Seventeen studies were included in the final analysis. Of the included studies, none were randomized, 2 were prospective in nature, and 4 compared outcomes of posterior sagittal anorectoplasty and LAARP. The studies included 124 patients (96 males, 28 females) with 80% reported as having high/intermediate malformations. All studies reported short-term outcomes. Reported outcomes included continence, rectal prolapse, the position of the rectum (7 studies using Kelly score), manometry (1 study), contrast enema (1 study), postanal endosonography (3 studies), and postoperative magnetic resonance imaging (3 studies). Outcomes varied widely between reports precluding a meta-analysis.
CONCLUSION
The number of studies dealing with LAARP is low. There is a need for both a standardization and improvement in the quality of reporting in LAARP research. This will ultimately allow for evidence-based surgical decision making.

Short and Long-Term Outcomes of PSARP versus LAARP and Single versus Staged Repair for Infants with High-Type Anorectal Malformations: A Systematic Review and Meta-Analysis.
BACKGROUND
We aimed to compare among patients with high-type anorectal malformations (ARM): (i) short- and long-term outcomes of laparoscopic-assisted anorectoplasty (LAARP) compared to classic posterior sagittal anorectoplasty (PSARP) and (ii) the results of single-stage versus staged PSARP.
METHODS
Using a defined search strategy, two independent investigators systematically reviewed the English literature. PRISMA guidelines were followed, and meta-analysis was performed using RevMan5.3.
RESULTS
Of 567 abstracts screened, 7 papers have been included (254 pts; 121 PSARP, 133 LAARP) in the first systematic review and meta-analysis. The length of hospitalization was shortened in LAARP versus PSARP (10.9 versus 14.4 days; < 0.0001). PSARP and LAARP were comparable in terms of early postoperative complications (28.9% versus 24.7%; = ns) and rectal prolapse (21.6% versus 17.5%; = ns). At long-term follow-up, the presence of voluntary bowel movements (74.0% versus 83.5%; = ns) and the incidence of soiling (45.5% versus 47.6%; = ns) were similar in both PSARP and LAARP. Six papers (297 pts) were included in the second systematic review, with three comparative studies included in the meta-analysis (247 pts; 117 one-stage, 130 staged procedures). No significant difference in terms of presence of voluntary bowel movements after single-stage versus staged procedures (72.6% versus 67.3%; = ns) has been detected.
CONCLUSIONS
LAARP seems to be a safe and effective procedure, showing short- and long-term outcomes similar to PSARP. One-stage PSARP could be a safe alternative to the classic three-stage procedure, even for those infants with high-type ARM. Further and larger comparative studies would be needed to corroborate these partial existing data.

BACKGROUND
There is wide variation in the clinical use of diagnostic tools for children with chronic constipation and functional/structural fecal incontinence (CCFSFI). Anorectal manometry (ARM) is a well-recognized technique to assess the function of the anorectum.
PURPOSE
Our aim was to perform an up-to-date review on ARM in pediatric patients with CCFSFI, with specific focus on the indication of use and protocol. Variation of its use in pediatrics will be explored.
METHODS
A systematic search was conducted for empirical studies utilizing ARM with a pediatric sample. A keyword search of literature published in English before July 2018 was conducted and updated to October 2019. Data on demographics, clinical information, study aims, ARM parameters and use of sedation/anesthesia were collected.
KEY RESULTS
A total of 227 studies were included in this systematic review. The age of study participants at the time of ARM ranged from birth to 18 years. ARM was most commonly used in patients with organic conditions (65%) compared to functional constipation (41%). In almost half [108/227 (48%)] of the studies, ARM was performed awake. The ARM parameters most frequently assessed were the rectoanal inhibitory reflex, which was evaluated in 198/227 studies (87%) and the anal resting pressure [166/227 studies (73%)].
CONCLUSIONS AND INFERENCES
This systematic review has highlighted the vast variation of ARM use within pediatrics and the need to strive toward standardization and use of consensus guidelines. We anticipate this will further advance our understanding of the pathophysiological mechanisms involved in children with defecation disorders.

Review
PURPOSE
This systematic review aims to give an overview of available evidence concerning the influence of anorectal malformations (ARM) on fertility.
METHODS
We conducted a search in PubMed, EMBASE and Cochrane Library conformed to the PRISMA standards. All studies reporting on fertility and ARM were included.
RESULTS
2,905 studies were identified. Based on title, abstract and full text, nine articles on 429 patients remained to answer the research question. Childbirth rate was the only reported outcome parameter to describe fertility. An overall childbirth rate of 27 % (range 0-57 %) was found. Mean age at time of study ranged from 23 to 35 years. There was no statistical significant difference in childbirth rate between female and male patients, based on seven studies (p = 0.45). Patients with a more complex type of ARM (imperforated anus without fistula, rectourethral bulbar and prostatic fistulas, rectobladderneck fistulas and cloacal malformations) had a lower childbirth rate compared to healthy controls, whereas in patients with a less complex ARM (rectoperineal or rectovestibular fistula) the childbirth rate was similar to healthy controls. Patients with a more complex type of ARM had a significant lower childbirth rate than patients with a less complex type of ARM (18 vs 47 %, respectively) (p = 0.0001). When further dividing these patients by gender, this difference was only seen in female patients (p = 0.04).
CONCLUSION
In patients with a more complex type of ARM a lower childbirth rate was found compared to healthy controls and patients with a less complex type of ARM. The latter was only seen in female patients. However, conclusions concerning fertility in ARM patients have to be taken with caution due to limited quality of the studies. Further investigation is recommended.

Gastroenterology Report Aug 2016Heterotopic gastric mucosa (HGM) is the most reported epithelial heterotopia, but it is very rare in the rectum and anus. (Review)
Review
BACKGROUND
Heterotopic gastric mucosa (HGM) is the most reported epithelial heterotopia, but it is very rare in the rectum and anus.
METHODS
The first case of an asymptomatic adult male with a large nonpolypoid HGM in the low rectum underwent complete resection by endoscopic submucosal dissection (ESD) is reported. The systematic review was based on a comprehensive search of MEDLINE, EMBASE and Google Scholar. Studies on humans were identified with the term 'heterotopic gastric mucosa in the rectum and /or anus.'
RESULTS
The search identified 79 citations, and 72 cases were evaluated comprising the present report. Congenital malformations were observed in 17 (24%) patients; rectal duplication accounted for most of the cases. The HGM was located in the anus and perineal rectum in 25 cases (41%) and low, middle and proximal pelvic rectum in 20 (33%), five (8%) and 11 cases (18%), respectively. Morphology was nonpolypoid in 37 cases (51%), polypoid in 26 cases (36%) and ulcerated in nine cases (13%). Specific anorectal symptoms were reported by 50 (69%) patients of the whole study population, and by 33 (97%) of 34 patients ≤ 18 years. Complications were observed in 23 cases (32%). The HGM was excised in 50 cases (83%). Endoscopic resection was performed in 17 cases (34%); resection was piecemeal in five of 12 lesions ≥15 mm, required argon plasma coagulation in two cases and was associated with residual tissue in two (17%). Intestinal metaplasia and an adenoma with low-grade dysplasia were described in three adults (4%).
DISCUSSION
This systematic review shows that the HGM in the rectum and anus may be associated with specific rectal symptoms and serious complications, mainly in the pediatric population, and a risk of malignancy in adults. Its complete excision should be recommended, and the ESD can overcome the technical limits of conventional endoscopic snare resection and avoid unnecessary surgery.

Review
BACKGROUND
Anorectal malformations are a spectrum of congenital anomalies of the rectum with high infantile survival rates and variable outcomes. Long-term (>10 years old) active problems associated with this condition have been poorly investigated.
OBJECTIVE
The purpose of this review was to systematically define the prevalence of the most common active long-term problems in patients with a history of anorectal malformation repair.
DATA SOURCES
MEDLINE, EMBASE, and the Cochrane Library were searched electronically using the OVID search platform.
STUDY SELECTION
Original articles from August 1, 1994, to October 20, 2015, that included outcome data for patients aged ≥10 years with anorectal malformation. Cloaca was excluded from the study.
INTERVENTIONS
Prevalence estimates of anorectal malformations were obtained from published articles. CIs were ascertained in the logit scale after transforming prevalence into log odds and were then transformed into the original scale. The same method was used for subgroup analysis investigating high and low anorectal malformations.
MAIN OUTCOME MEASURES
The overall prevalences of fecal, urinary, and sexual dysfunction were analyzed.
RESULTS
Twelve studies including 455 patients with a history of anorectal malformation repair were included for analysis. The range of reported prevalence of long-term active problems was as follows: fecal incontinence, 16.7% to 76.7%; chronic constipation, 22.2% to 86.7%; urinary incontinence, 1.7% to 30.5%; ejaculatory dysfunction, 15.6% to 41.2%; and erectile dysfunction, 5.6% to 11.8%.
LIMITATIONS
The study was limited by its retrospective, small size; multiple complex associated anomalies often not reported; and heterogeneous composition of patients with limited stratification analysis.
CONCLUSIONS
There is an overall high prevalence of active long-term issues in adolescents and young adults with anorectal malformations. Additional multicenter research is needed to define characteristics and predictors of long-term outcome, to implement effective follow-up, and to transition to adult health care.

Review
BACKGROUND
Reconstructive surgery is performed in patients with cloacal malformations to achieve anorectal, urological, and gynecological function. The aim of this study was to evaluate the functional outcome of cloacal malformation repair as reported in literature.
METHODS
A systematic literature search was conducted according to PRISMA guidelines using PubMed, EMbase, and Web-of-Science. Records were assessed for the reporting of functional outcomes, which was divided into anorectal, urological, or gynecological function. Studies were used in qualitative (Rangel score) and quantitative syntheses.
RESULTS
Twelve publications were eligible for inclusion. Voluntary bowel movements were reported in 108 of 188 (57%), soiling in 146 of 205 (71%), and constipation in 31 of 61 patients (51%). Spontaneous voiding was reported for 138 of 299 patients (46%). 141 of 332 patients (42%) used intermittent catheterization, and 53 of 237 patients (22%) had a urinary diversion. Normal menstruations were reported for 25 of 71 patients (35%). Centers with limited experience reported similar outcome compared to centers with more experience (≥1 patients/year).
CONCLUSION
In this review we present functional outcome of the largest pooled cohort of patients with cloacal malformations as reported from 1993 to 2012. Functional disturbances are frequently encountered in anorectal, urological, as well as gynecological systems. Reporting of functional outcome in these patients should improve to increase knowledge about long-term results in patients with this rare malformation and to reach higher study quality. Especially, sacral and spinal anomalies should always be reported given their impact on functional outcome. Specialized care centers may be of great importance for patients with rare and complex conditions.

AIM
The optimal surgical treatment for anatomical anal stenosis (AS) remains to be determined. The aim of this study was to determine the rates of complications and recurrence after anoplasty for anatomical AS and, wherever feasible, compare the outcomes for the various techniques.
METHOD
A PROSPERO-registered systematic review was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Medline, PubMed, Embase, Cochrane Library of Systematic Review, Scopus and Web of Science were searched for articles published up to May 2021. Studies that assessed the outcomes of anoplasty in adult patients with anatomical AS were selected. The primary outcomes were complications and recurrence. The methodological quality of studies was appraised using the Joanna Briggs Institute critical appraisal tools.
RESULTS
From the total of 2705 unique screened records, 151 were assessed for eligibility. Only 29 studies (two prospective) met the inclusion criteria, reporting data on 556 patients [mean age 53 (18-83) years, 46% female]. Previous history of surgery for haemorrhoidal disease accounted for three quarters of cases. A total of 14 types of anoplasty were found, with the Y-V flap being the most performed technique [27% of cases (n = 149)]. Complications frequently occurred, with a pooled prevalence of 10.2% (95% CI 3.9%-24.1%) after Y-V flap and 11.5% (5.3%-23.0%) after rhomboid/diamond flap. Patients undergoing house flap achieved better results in terms of clinical improvement, satisfaction and quality of life compared with Y-V flap and rhomboid/diamond flap. When considering only studies with at least 12 months of follow-up, the pooled prevalence of recurrence was 4.7% (2.2%-9.8%), with significantly higher rates observed in the prospective versus retrospective series [pooled prevalence 18.9% (11.5%-29.5%) vs. 3.6% (1.7-7.8%), respectively; p < 0.001].
CONCLUSION
Both complications and recurrence were significantly lower after house flap compared with rhomboid/diamond and Y-V flap. Better designed multicentre studies with longer follow-up are needed to confirm these findings.
