ARM in ARM? Investigating the co-occurrence of anorectal malformations and labioscrotal anomalies.
Anorectal malformations (ARMs) are known to be associated with other defects, however there is no evidence addressing the co-occurrence of ARMs with anomalies of structures derived from the labioscrotal folds. We performed a systematic review (Prospero: CRD420251013945) aiming at investigating correlations and patterns between ARMs and labioscrotal anomalies (LSAs), when presenting simultaneously. Our search identified 1642 articles. After abstract screening, 344 full texts were assessed and 144 met the inclusion criteria. In total, these reported on 319 individual cases with both ARM and LSA. Individuals with complex ARMs had proportionally the most LSAs associated with their ARM - 58.4% of these were associated with only a single LSA. For 'high' and 'low' ARMs, 66.0% and 77.0% of cases were associated with a single LSA respectively. As data reporting prevalence of each type of ARM lacks information about LSAs, the potential to predict the presence of LSAs according to type of ARM is limited. Nevertheless, this review demonstrates a frequent association of ARMs with LSAs, that has not been previously described. This evidence highlights the importance of early screening and timely management of LSAs in patients with any type of ARM, with close collaboration between paediatric surgeons, urologists and other clinicians.

Surgical management of anterior sacral meningoceles: a case series and systematic review
PURPOSE: Anterior sacral meningoceles (ASMs) are rare forms of spinal dysraphism caused by anterior herniation of meninges through a sacral defect. Surgical management is the treatment of choice, yet the optimal approach remains debated. This study compares outcomes of three main surgical approaches-anterior transabdominal, posterior transsacral, posterior sagittal (PSARP-type)-focusing on the efficacy and safety of the PSARP-type. METHODS: A retrospective single-center analysis was conducted on eight patients treated for ASM between 2008 and 2025. Demographic, clinical, radiological, functional data were reviewed. Outcomes included recurrence, reoperation, sac size reduction, bladder function; complications were categorized as early or late. A systematic literature review was performed according to PRISMA guidelines. RESULTS: Eight patients (6 females, 2 males; mean age 19.4 years) underwent surgery (five anterior Pfannenstiel incision, two posterior sagittal, one posterior transsacral). All were symptomatic, 87.5% had associated malformations. Sac reduction was achieved in 87.5% of cases, with no new neurological deficits. Complications were mild and self-limiting, including transient urinary retention and cerebrospinal fluid fistula managed with lumboperitoneal shunt. The literature review (49 studies, 68 patients) confirmed female predominance (81%), association with Marfan and Currarino syndromes (35%), preference for posterior approaches (70%), which showed lower morbidity and recurrence rates. One postoperative death (1.4%) was reported. CONCLUSIONS: Posterior approaches-particularly the PSARP-type-provide safe, effective, and functionally favorable alternatives to anterior surgery for ASM, offering optimal exposure, precise dural closure, superior cosmetic outcomes with minimal morbidity. The anterior route should be reserved for large or high-lying lesions. Further multicenter studies with longer follow-up are warranted.
