Review
Complex perianal fistula is a highly debilitating and difficult to treat condition. Local mesenchymal stem cell (MSC) therapy for perianal fistula has shown considerable promise but still remains controversial. Therefore, we performed the meta-analysis to evaluate the efficacy and safety of local MSC therapy for complex perianal fistula. PubMed and Embase databases were searched for published randomized clinical trials (RCTs) that reported local MSC therapy for complex perianal fistulas. The effectiveness and safety data analysis was conducted using RevMan5.3. Subgroup analyses were performed based on the characteristics of the studies. Seven RCTs with 730 participants were included. Local MSC treatment showed significantly higher healing rate (HR) of perianal fistulas compared to control (odds ratio (OR) = 2.03; 95% confidence interval (CI) 1.50, 2.74; < 0.00001). MSCs combined with fibrin glue therapy can improve the HR compared with fibrin glue alone (OR = 3.27; 95% CI 1.15, 9.28; = 0.03). Subgroup analyses showed that local therapy can improve the HR in patients with perianal fistulas associated with Crohn's disease (CD) (OR = 2.05; 95% CI 1.41, 3.00; = 0.0002) and cryptoglandular origin (no-Crohn) (OR = 2.98; 95% CI 0.86, 10.29; = 0.08). The pooled OR for studies that combined reepithelialization of the external opening with pelvic magnetic resonance imaging (MRI) to evaluate the healing of fistulas was 1.77 (95% CI 1.28, 2.45; = 0.0006). The pooled OR for studies where fistula healing was defined as complete reepithelialization of external openings was 5.92 (95% CI 1.34, 26.15; = 0.02). Both autologous MSCs (OR = 3.19; 95% CI 1.05, 9.65; = 0.04) and allogeneic MSCs (OR = 1.97; 95% CI 1.34, 2.91; = 0.0006) can obtain higher HR for perianal fistula compared with control. The adipose-derived MSC group can obtain higher HR than the control group (OR = 2.29; 95% CI 1.38, 3.79; = 0.001). There were no significant differences in adverse events (AEs) (OR = 1.06; 95% CI 0.71, 1.59; = 0.77). None of the adverse events was judged to be related to MSCs. Our study supported that local MSC therapy alone or combined with fibrin glue is safe and efficacious for complex perianal fistula. In the future, more RCTs are needed to confirm this conclusion.

Case Reports in Dermatology 2024A peculiar spongy appearance of the perianal skin was observed in a patient who underwent wide excision surgery for inguinal and gluteal hidradenitis suppurativa (HS).
INTRODUCTION
A peculiar spongy appearance of the perianal skin was observed in a patient who underwent wide excision surgery for inguinal and gluteal hidradenitis suppurativa (HS).
CASE PRESENTATION
This peculiar appearance was observed in a 62-year-old male patient. It included multiple orifices and cavities forming the spongy aspect of the perianal skin with multiple cysts and giant comedones. The perianal lesions were asymptomatic and the patient had never received any perianal treatment for the comedones or cysts. Histopathology was performed and demonstrated dilated hair follicles with flaky keratin and loose hair shafts in the center. The spongy appearance was most likely the result of spontaneous shedding of the cystic contents.
CONCLUSION
We suspect that the "cystic sponge anus" might be associated with HS, smoking, the male gender, and may yet be another expression of an occlusive follicular disease. Future studies will be needed to clarify the prevalence and comorbidities of the "cystic sponge anus."

Perianal fistulae are commonly complicated by abscesses and ramifications, which have well-recognized imaging morphology. Less commonly, atypical findings of solid enhancing mass-like lesions with no fluid component are associated with chronic and recurrent fistulae, the etiology of which includes inflammatory masses as well as locally aggressive malignancy. The latter predicts poorer prognosis and warrants extensive surgical resection. The reading radiologist must identify the unusual appearance, be aware of the possible etiologies, and if appropriate recommend prompt tissue sampling to exclude malignancy. This is pertinent as it determines surgical management, which is crucial in achieving a potential curative outcome.

Review
Perianal fistulas and abscesses may be cryptogenetic or associated with inflammatory bowel disease (IBD), specifically Crohn's disease. Proper identification and classification of these lesions are paramount for correct therapeutic management. Current diagnostic modalities include MRI (magnetic resonance imaging), EUS (endoscopic ultrasound), EUA (exam under anaesthesia) and recently, transperineal ultrasound (TPUS). The latter has been proposed as a noninvasive, easily available and cost-effective technique to diagnose, assess and follow up perianal disease particularly in IBD patients. This pictorial review focuses on the role of TPUS in clinical practice, highlighting the features of fistulas and abscesses.

BACKGROUND
Perianal fistulae can undermine physical, emotional, and social well-being in patients with Crohn's disease and are challenging to manage. Social media offers a rich opportunity to gain an in-depth understanding of the impact of perianal fistulae on patients' daily lives outside of controlled environments. In this study, we conducted social media analytics to examine patients' experiences with perianal fistulae and assessed the impact of perianal fistulae on patients' behavior and overall well-being.
METHODS
We used a mixed-method approach to examine 119 986 publicly available posts collected from 10 Crohn's disease forums in the United States between January 01, 2010 and January 01, 2020. Discussions related to Crohn's perianal fistulae were retrieved. We randomly selected 700 posts and qualitatively analyzed them using an inductive thematic approach. We then applied a latent Dirichlet allocation probabilistic topic model to explore themes in an unsupervised manner on the collection of 119 986 posts.
RESULTS
In the qualitative analysis, 5 major themes were identified: (1) burden of perianal fistula; (2) challenges associated with treatment; (3) online information seeking and sharing; (4) patient experiences with treatments; and (5) patients' apprehension about treatments. In the quantitative analysis, the percentages of posts related to the major themes were (1) 20%, (2) 29%, (3) 66%, and (4) 28%, while the topic model did not identify theme 5.
CONCLUSIONS
Social media reveals a dynamic range of themes governing patients' perspectives and experiences with Crohn's perianal fistulae. In addition to the biopsychosocial burden, patients frequently express dissatisfaction with current treatments and often struggle to navigate among available management options.

Review
Perianal Crohn's disease remains a challenging condition to treat and can have a substantial negative impact on quality of life. It often requires combined surgical and medical interventions. Anti-tumor necrosis factor (anti-TNF) therapy, including infliximab and adalimumab, remain preferred medical therapies for perianal Crohn's disease. Infliximab has been shown to be efficacious in improving fistula closure rates in randomized controlled trials. Clinicians can be faced with a number of questions relating to the optimal use of anti-TNF therapy in perianal Crohn's disease. Specific issues include evaluation for the presence of perianal sepsis, the treatment target of therapy, the ideal time to commence treatment, whether additional medical therapy should be used in conjunction with anti-TNF therapy, and the duration of treatment. This article will discuss key studies which can assist clinicians in addressing these matters when they are considering or have already commenced anti-TNF therapy for the treatment of perianal Crohn's disease. It will also discuss current evidence regarding the use of vedolizumab and ustekinumab in patients who are failing to achieve a response to anti-TNF therapy for perianal Crohn's disease. Lastly, new therapies such as local injection of mesenchymal stem cell therapy will be discussed.

Observational Study
Infantile perianal protrusion is characterized by a skin fold located in the perianal area. It is a relatively recent reported condition and affects both infants and prepubertal children with a clear female predominance. Three types are recognized: constitutional/congenital, acquired, and associated with lichen sclerosus et atrophicus. We report eleven new cases, three of whom have the defect in locations that have been reported only once before. We would like to increase the awareness of this condition to avoid erroneous diagnostic and therapeutic procedures.

Clinical and MRI Evolution After Local Injection of Bone Marrow-Derived Mesenchymal Stem Cells in Perianal Fistulae in Crohn's Disease: Results From a Prospective Monocentric Study.
BACKGROUND
Local injection of adipose tissue-derived mesenchymal stem cells [MSCs] is effective in fistulizing perianal Crohn's disease [CD]. Less is known about bone marrow-derived MSCs and little is known about predictive factors of response and magnetic resonance imaging [MRI] evolution of the fistulae after MSC injection. Our aims were to evaluate the safety and clinical outcome of bone marrow-derived MSC injection for perianal fistulizing CD, to evaluate the MRI evolution of the fistulae and to identify factors associated with fistula closure.
PATIENTS AND METHODS
All CD patients with perianal fistula and appropriate drainage with a seton without abscess at MRI were eligible. Clinical examination, biomarkers and pelvic MRI were performed at weeks 0, 12 and 48. The clinical outcome was assessed by closure of the treated external openings at clinical examination and MRI exploration.
RESULTS
Sixteen patients with a median age of 49 years and a median duration of perianal CD of 8 months were included. No unexpected safety event occurred. At weeks 12 and 48, 9/16 and 8/16 patients had complete fistula[e] closure, respectively, whereas 11/16 patients had at least partial closure. At MRI, the degree of fibrosis increased significantly after MSC injection. In total, 86% of patients with >80% of fibrosis of the fistula tract at week 48 had fistula closure. Fistula closure at week 12 was predictive of fistula closure at week 48. The MAGNIFI-CD did not change significantly over time.
CONCLUSION
Open-label injection of bone marrow-derived MSCs was safe and was effective in half of the patients in fistulizing perianal CD and induced significant MRI changes associated with favourable clinical outcome.

Stool specimens are frequently used to detect gastrointestinal tract colonization with antimicrobial-resistant enteric bacteria, but they cannot be rapidly collected. Perianal swab specimens can be collected more quickly and efficiently, but data evaluating their suitability as a specimen type for this purpose are sparse. We performed selective culture for extended-spectrum β-lactamase-producing (ESBL-E) and fluoroquinolone-resistant (FQRE) using paired perianal swab and stool specimens that were collected within 1 day of each other from hematopoietic cell transplant recipients and patients with acute leukemia. Nineteen (7.6%) of 251 stool specimens yielded ESBL-E and 64 (26%) of 246 stool specimens yielded FQRE. The positive percent agreement of perianal swab specimens compared to stool specimens was 95% (18/19; 95% confidence interval [CI], 74% to 100%) for detecting ESBL-E and 95% (61/64; 95% CI, 87% to 99%) for detecting FQRE. The concordance between specimen types was 98% (95% CI, 97% to 100%). Perianal swabs are a reliable specimen type for surveillance of the gastrointestinal tract for ESBL-E and FQRE.

OBJECTIVES
The diagnosis of fecal incontinence is challenging and complex. One of the most significant causes of fecal incontinence is trauma in the perianal area. The most important cause of such trauma is birth trauma. It is hard to evaluate patients and plan treatment. Surgical method is determined by the severity of sphincter damage and injuries formed in the organs in the perianal area. The aim of this study, therefore, was to analyze the cases of patients who had undergone sphincter repair because of acute injuries in the perianal area.
MATERIAL AND METHODS
The cases of 15 patients with perianal area injuries who had presented to Necmettin Erbakan University Meram Medical School's General Surgery Clinic between 2010 and 2015 were retrospectively analyzed. Data on age, sex, form of injury, severity of injury, time of first response, form of repair, injury problems, and post-operative complications of the patients were investigated. The patients' long-term results were analyzed.
RESULTS
While 5 of the patients were male, 10 were female. 9 of the female patients had birth trauma, while one had injury during sexual intercourse. While all of the patients received sphincteroplasty, 10 had levatoroplasty. All the female patients received vaginoplasty.
CONCLUSION
We are of the opinion that it is significant to have surgical intervention before tissue edema develops.
